How to Convert ROG Phone 2 Tencent Edition to Global Edition (CN ROM to WW ROM)

How to Convert Asus ROG Phone 2 Tencent Edition (CN ROM) to Global Edition (WW ROM)

In this guide, I have provided step-by-step instructions on how to convert ROG Phone 2 Tencent Edition (with CN ROM) to Global Edition ( with WW ROM), or vice-versa. This could be done by properly installing the global ROM on your phone and changing its fingerprint from ‘CN’ to ‘WW’. The same method could also be used to install CN ROM and convert your phone back to the Tencent edition.

Asus released its second gaming smartphone in 2019 as the ROG Phone 2, but its availability was limited to China for months. In September 2019, the Taiwanese manufacturer released the ROG Phone 2 in the US and Indian markets, labeled as the ‘Global edition’ (Also known as the ‘STRIX edition’). Apart from minor differences in specs, the only major difference between the two editions was the pre-installed ROM (software).

There are a couple of reasons why you would want to convert your phone and install the Global ROM on it. For starters, the Global ROM offers much quicker software updates, it supports more themes and gamer profiles in the ROG Armoury Crate software, and also comes with the least amount of pre-installed system apps (bloatware). Moreover, if you purchased the Tencent Edition of the phone from the grey market and had it shipped to you outside China, you might face software issues like video recording errors, etc.

So, for whatever reason that you might want to do it, this guide will take you through the complete process in a step-by-step manner.

If you own the ROG Phone, then you could follow my recent tutorial to convert the ROG Phone 3 Tencent to the Global edition.

Properly Converting ROG Phone 2 Tencent Edition to Global Edition (or Vice-versa)

Asus does provide firmware files for both the editions for the purpose of manual flashing/upgrading. And while you can use the provided firmware to flash the Global WW ROM on a Tencent ROG Phone 2, or vice-versa, it will not properly convert your phone. This will also result in things like not being able to re-lock the bootloader, take OTA updates, SafetyNet issues, and thus not being able to use apps (like banking and password apps) that rely on SafetyNet.

That’s because the firmware (ROM) files provided by Asus lack the ‘recovery’ partition, where the device’s ‘Product ID’ and ‘Fingerprint’ are stored. So, in order to properly convert your ROG Phone 2 Tencent Edition to Global Edition, you must change the phone’s Product ID and Fingerprint from ‘WW’ to ‘CN’.

So, how can this be done? According to XDA Senior Member JasonX, you can install Global WW ROM on your ROG Phone 2 Tencent Edition or China CN ROM on Global Edition by using the RAW firmware file. These files are basically used by Asus internally or in their authorized service centers. Flashing this RAW firmware file will forcibly overwrite all the device partitions.

In order to fully convert the phone, it is VERY IMPORTANT to also change the device’s fingerprint from ‘CN’ to ‘WW’ (or vice-versa) manually. To do this, you will need to root the phone and use a root file manager app. Once everything is done, you can unroot the phone and relock the phone’s bootloader.

Now without any further ado, let us get to the instructions.

Before You Begin

Take a look at some important pre-requisites and notes listed below.

  • Make sure to take a complete backup of all your important data including apps, music, videos, photos, contacts, messages, etc. Your phone will be completely formatted while performing the conversion. If you need it, you can also follow our detailed guide on backing up Android devices.
  • Charge your ROG Phone 2 to a sufficient battery level. This shall dismiss any possibility of your phone suddenly shutting down in the middle of the process.
  • Log out of your Google account on the phone to prevent locking out of your device after the conversion due to Google’s FRP (Factory Reset Protection).
  • Use a Windows PC with x64/64-bit architecture. Certain users have reported that their device bricked because the RAW firmware was not compatible with x86/32-bit PCs.
  • When asked to connect your phone to the PC, use a good quality USB-C cable and connect it to the side of the phone (not the charging port on the bottom).
  • In order to convert your phone to Global Edition (or back to Tencent Edition), you will need to unlock the phone’s bootloader (as mentioned in the instructions). In doing so, your phone will lose its official limited warranty offered by Asus. So, make sure that you understand this completely before you proceed.

How to Convert ROG Phone 2 Tencent Edition to Global Edition

Converting the ROG Phone 2 Tencent Edition and installing Global ROM on it is a five-step process.

The first step is to unlock your phone’s bootloader. Once that is done, the second step is to flash the RAW firmware file via Fastboot. Then, the third step is to root the phone via Magisk and install the Root Explorer app. This is followed by the fourth step, where you have to use the root explorer to manually change the device’s fingerprint. Once everything is done, the fifth and last step is to unroot the phone and relock the bootloader so that you can receive OTA updates.

I have split the instructions into these five (5) major steps so that it’s easier for you to understand the procedure. The instructions below will take you through each of these steps in detail. Let’s begin.

Note: These same instructions can also be used to convert your phone back to Tencent Edition. If you want to do it, simply use the China CN RAW firmware file instead of the Global one.

Step 1: Unlock the Bootloader

In order to flash the RAW firmware and convert your phone, the first step is to unlock the bootloader of your ROG Phone 2. Unlocking the bootloader is quite easy and could be done by using the official unlock tool provided by Asus.

Start by downloading the official Asus Unlock Tool (in APK file format) according to the Android version installed on your phone.

A newer version of the unlock tool has been released that supports both Android 9 Pie and Android 10. Thanks, Trinugo!

Once you have downloaded the APK file, install it on your phone. If you’re new to Android and don’t know how to install an APK file, then please refer to the instructions in this tutorial.

After the app has been installed, go to the app drawer and launch the ‘Unlock Device Tool‘ application on your phone. In the app’s window, scroll until the end and check ‘Agree‘. Then press on ‘Tap to unlock your device‘ option to unlock the bootloader on your ROG Phone 2.

Unlock Bootloader on Asus ROG Phone 2

Your phone will automatically reboot and erase all your data. The bootloader should now be fully unlocked. Once it is, you will see a bootloader unlocked warning message on the screen and your phone will reboot into the system (OS).

Step 2: Flash Global WW ROM on ROG Phone 2 Tencent Edition

Now that your phone’s bootloader is unlocked, it can accept fastboot commands for flashing the partitions (RAW firmware).

  1. First, turn off your ROG Phone 2 completely and boot it into Fastboot Mode. To do so, hold the Volume Up and Power keys simultaneously while the phone is powered off.
  2. Connect the phone to the PC via a USB cable while it’s in Fastboot Mode.
  3. Now, download the RAW Firmware file of the Global WW ROM on your PC.
  4. Once downloaded, extract the contents of the ZIP file using an archive utility like 7-Zip.
  5. The extracted files should contain the required Android SDK tools, the flashing scripts, and the actual RAW firmware file that will be flashed onto your phone.

  6. Finally, double-click on the ‘flashall_AFT.cmd‘ flashing script to flash the RAW firmware on your ROG Phone 2.

As soon as you launch the script, you should see a command-line (CMD) window on your PC’s screen. The complete flashing process could take a couple of minutes to finish. During this time period, do not disrupt the connection between the phone and the PC and also do not close the CMD window.

Flash RAW Firmware on Asus ROG Phone 2

Once the flashing finishes, your ROG Phone 2 will automatically reboot into the OS.

Step 3: Root your Phone and Install Root Explorer App

At this point, your phone has the Global WW ROM installed. However, it’s not fully converted until you change the device’s fingerprint from ‘CN’ to ‘WW’. To do this, you must root your phone and use the Root Explorer application.

  1. First, download the latest version of the Android SDK platform-tools from here. Once downloaded, extract the file (e.g. platform-tools_r29.0.6-windows.zip) to the C:\ drive of your Windows PC. The extracted folder (platform-tools) should contain all the Android tools including the fastboot tool that you’ll need for flashing.
    • Note: From here onwards, all the files are to be flashed from this ‘platform-tools’ folder where the Android SDK tools are installed
  2. Next, download the Magisk pre-patched boot image for your ROG Phone 2 from below, according to the firmware version you have installed. For example, if you have installed ‘WW-17.0210.2001.60’, then you must use the ‘WW-17.0210.2001.60’ boot image only. Using a boot image from a different firmware version can result in a soft brick.
  3. Once downloaded, extract the ZIP file to get the ‘magisk_patched.img‘ file and copy it file to the ‘platform-tools‘ folder in the C:\drive. Then while holding the SHIFT key, right-click on any empty space inside the folder. Select the ‘Open PowerShell window here‘ option from the contextual menu that appears on the screen. A blue-colored PowerShell window should open up on your PC.
    Copy Patched Boot Image to the Platform-tools Folder
  4. Now, power off your ROG Phone 2 completely and boot it into Fastboot Mode by holding the Volume Up and Power keys together. Then connect your phone to the PC via a USB cable.
  5. Issue the following command to ensure that your phone is properly detected by the PC over fastboot:
    .\fastboot devices
  6. Enter the following command in the PowerShell window to flash the patched boot image and root your ROG Phone 2:
    .\fastboot flash boot magisk_patched.img

    Flash Magisk Patched Boot Image to Root Asus ROG Phone 2

  7. After flashing the boot image, reboot your phone into the system by entering the following command:
    .\fastboot reboot
  8. Your phone should now be rooted. To confirm, go to the app drawer and launch the Magisk Manager application. If you do not see the Magisk Manager app in the app drawer, then download the latest APK from here and install it.
  9. Now, download the APK file of the Root Explorer app from here and install it on your phone.

Step 4: Change Device Fingerprint from ‘CN’ to ‘WW’

Now comes the actual part where you have to manually change the device’s fingerprint from ‘CN’ to ‘WW’. This step is extremely important to fully convert your Tencent edition ROG Phone 2. Without doing this step, even though you will have the Global WW ROM installed, but you will still not receive FOTA updates. That’s because your phone still has the ‘CN’ fingerprint that will mismatch with the installed Global WW ROM.

To do this, go to the app drawer and launch the ‘Root Explorer‘ application that you installed during the previous step. As soon as the app is launched, it will prompt you to grant superuser permissions. So, press ‘Grant‘ to grant the request.

Grant Superuser Permissions to Root Explorer on Asus ROG Phone 2

Next, press on the ‘ROOT‘ tab to access the root storage of your phone. Navigate to ‘/Vendor/Factory‘ folder and find the file with the name ‘COUNTRY‘. Tap on the file and open it with the ‘Text Editor‘. Now, change the fingerprint by renaming ‘CN‘ to ‘WW‘ (in caps). Once you have made the change, tap the 3-dot buttons on the top right and press ‘Save Changes‘. Editing and saving this file will create a backup of this file in the same directory as ‘COUNTRY.bak‘. Simply delete this backup file.

Change Device Fingerprint from 'CN' to 'WW' on Asus ROG Phone 2

Now, the next thing you have to do is enable the hidden Armoury Crate themes and wallpapers. To do this, navigate to ‘/System/etc/AsusTheme/themes‘ and delete the file that’s named ‘hidden‘. That’s it! You have successfully changed your device’s fingerprint from ‘CN’ to ‘WW’ and also enabled the hidden themes and wallpapers available in the Global WW ROM. For the changes to take effect, simply reboot your phone.

Step 5: Unroot and Relock the bootloader on your ROG Phone 2

Although the conversion is complete, your ROG Phone 2 is still rooted at this point. If you wanted to root, you wouldn’t need to follow this step and can always install updates manually. But if you’d like to continue receiving OTA updates, you’d need to unroot and relock the bootloader on your phone. To do this, follow the instructions listed below.

  1. Power off your ROG Phone 2 and boot it into Fastboot Mode by holding the Volume Up and Power keys simultaneously while the phone is powered off.
  2. Connect the phone to the PC via a USB cable while it’s in Fastboot Mode.
  3. Now, download the stock boot image on the PC, according to the firmware version currently installed on your phone.
  4. Extract the downloaded ZIP file and copy the extracted ‘boot.img‘ file to the ‘platform-tools‘ folder in the C:\ drive where the Android tools are present.
    Copy Stock Boot Image to the Platform-tools Folder
  5. While holding the SHIFT key, right-click on any empty space inside this folder, and select the ‘Open PowerShell window here‘ option.
  6. Now, enter the following command to flash the stock boot image file and unroot your ROG Phone 2:
    .\fastboot flash boot boot.img

    Flash Stock Boot Image to Unroot Asus ROG Phone 2

  7. Your phone is now unrooted, to further relock the bootloader, enter the following command:
    .\fastboot oem asus-csc_lk

Your ROG Phone 2 should now be unrooted and the bootloader should be locked. At this point, it will still be in the Fastboot Mode. Simply press the volume keys until you see ‘Start‘ in Fastboot Mode, then press the power key to confirm. This will boot your phone directly into the stock recovery and you will see the “Can’t load Android system. Your data may be corrupt…“. To fix this, press the power key to select ‘Factory data reset‘ and then select ‘Yes‘ to confirm and perform a factory reset.

After doing this, your ROG Phone 2 will reboot into the system (OS) with the Global ROM installed, along with the ‘WW’ fingerprint. To verify that the fingerprint was changed successfully, just download the ‘Device Info HW‘ app on the phone and run it. Under the ‘System’ tab of the app, you can verify that the device’s fingerprint shows as ‘WW’ instead of ‘CN’.

That’s it! You have successfully installed Global WW ROM, changed the fingerprint, and converted your ROG Phone 2 Tencent Edition to Global Edition. You should now be able to receive OTA updates directly from Asus.

If you have any questions regarding the method shared here or face any issues while performing the instructions, please feel free to comment below and let me know. I will try to the best of my knowledge to help you.

  1. Hi, thanks for your help, I have followed the above steps to complete CN to WW, how long does it take to receive the OTA? (Not manual update)

  2. Hi !

    I’m experiencing a problem , my ROG2 bootloader is unlocked , and PC recognized my device by using fastboot command fastboot devices since it return my serial.

    i run the flashall_AFT.cmd then after a while my phone automatically reboots and it is stuck in ROG Logo. i checked at the bottom of this post to do a factory reset via recovery. so i go to bootloader and scroll to Recovery when i choosed it , it only reboots and goes back to ROG Logo and stuck there.

    i redo the steps but still meeting the same issue. any help?

    1. Hi, are you trying to convert the Tencent into Global edition or Global-to-Tencent?

      Which RAW firmware file did you use?

    2. Hi, are you trying to convert the Tencent into Global edition or Global-to-Tencent?

      Which RAW firmware file did you us

      Hi Dhananjay Bhardwaj ,

      yes , i’m trying to convert the CN tencent version to WW global version.. bootloader is unlock using APK from ASUS since i see the bootloader unlock message before starting up.

      i used the 2009.49 RAW version.. now i can’t do anything about it.. i tried 5x already and always stuck at ROG Logo.. i tried to flash TWRP for ROG2 android 10 , both official and unofficial but every time i send the command ‘ fastboot boot twrp10.img ‘ the phone reboots but not in twrp but it will stuck on ROG Logo. also in fastboot mode scrolling to recovery after selecting it will reboot and stuck at the Logo agian…

    3. Okay, that’s a first for me.

      Have you tried another RAW firmware from the list?

      If nothing works, try flashing the firmware through EDL mode. Here’s the link to the guide: https://www.thecustomdroid.com/rog-phone-2-unbrick-guide/

      Yes , i tried different version of Raw File with no avail , it all ends up being stuck on ROG Logo

      i also follow your unbrick guide via EDL everything was a success in xiaomiflashtool also in qfil but both i can’t go to recovery it will just stuck in ROG logo as well :/

      on the other hand i manage to boot the phone using a different QFIL file , although it’s like intended for debugging since in build ‘ OPEN_phone-userdebug 9 PKQ1.190414.00116.0601.1903.41-0-F release Keys ‘

    4. Oh. Could you share the source of the QFIL firmware you used?

      Have you tried flashing the CN RAW firmware and check if that makes any difference?

    5. Hi ,

      yes this is the source for that qfil , but again it is intended for debugging since most functions are not working and kinda clunky..

      https://gsmraid.com/firmware/asus/asus-rog-phone-2-i001-zs660kl/505/qfil-flash-file-firmware-asus-rog-phone-2-i001-zs660kl-zs660klfactorymp16-0501-1903-41_m1-9-23/

      so what i did when i flashed that qfil i used a stock rom v1910 and manage make it work , i was greeted with the rog logo animation the bar with different colors and the setup wizard like an Xmode. and now i’m facing a problem :/

      i was locked out with FRP :/ and my phone can’t connect to wifi.. pressing the ON/OFF is not working it’s like always off , no signal reception with simcard and data.

      maybe u have an idea how to fix such problem?

      Thank !

    6. I don’t have much knowledge about that factory software.

      Have you tried if you could boot the TWRP recovery image using the ‘fastboot boot’ command?

    1. Thanks for pointing it out. I cross-verified it and according to Asus, this latest unlock tool works on both Android Pie and Android 10. I will update the links right away.

    1. Hi Eric, I am not sure if I know what ‘B28’ means. Could you please explain?

    2. Yes, indeed it is. I went through this thread you linked and I think users over there are already trying to find out a way to renable that specific cellular band.

    1. I have added the stock boot image for WW-17.0240.2009.49. Please check and use that.

  3. hi im stuck at endless bootloop. also i cant turn it off to go to fastboot mode. how to fix this. im so screwed

    1. At what step did this happen exactly? Which RAW firmware did you use? Please provide more details.

      As for the loop, hold the Power button for 8-12 seconds to forcibly turn off the phone, then reboot into Fastboot.

  4. Please Sir! I have a problem to delete the “hidden” from “THEMES”.The system show “Delete failed” alert.
    How to do I solving this problem? Help me sir!

    1. Deleting the “hidden” file from the “THEMES” folder is probably the most tricky part. You’d need to close the root explorer and try deleting again. Some users even had to repeat this as much as 15 times.

  5. Olá Dhananjay

    Fiz o procedimento de conversão utilizando a “ROM WW_ZS660KL_17.0240.2004.9_M3.23.44.9-ASUS_1.1.185_Phone-user.raw.zip” acredito que tenha corrido tudo ok, porém essa ROM não está mais para download no site da Asus, aí vem a pergunta qual é a ROM seguinte para atualização ?
    A WW-17.0230.2004.60 ou WW-17.0240.2007.27, também percebi que o Android 10 consome mais bateria que o Android 9, quanto as atualizações são efetuadas na sequência ou pode ser instalada a última versão WW-17.0240.2009.49 ?
    Quem está na última versão relata algum tipo de problema ou está estável rodando liso…..
    Desde já obrigado.

  6. Would love if you could do a ROG 3 Tencent to WW version of this guide. A lot of people are looking one.

    Thank you!

    1. Matts, I am myself looking for the same. I will dig in deeper and if I end up finding something that really works, I will surely post a guide on it.

  7. Hello
    Searching for help with upgrading my ASUS ROG II from Android 9 to Android 10. When I try to run the firmware update downloaded from ASUS it stalls and then gives an error message – and will not complete the install. My phone says WW_16 version but ASUS tells me it is Tencent and upgrade not available. I have tried both WW and CN versions – neither works. And ASUS will not support here in NZ. The shop I purchased it from is denying all knowledge and help!
    Are you able to offer any suggestions?

  8. I was stuck on the unlock bootloader, which always mention unkown error, please try again later.
    Do you have any solutions? I did try to do it manually with EDL but it was not successful..

    I have downgraded the firmware from android 10 to android 9, also no hope.

    Could anyone help on this?

  9. hallo brother … I have succeeded in changing the Chinese ROM into a global ROM, but the problem is the system cannot update via FOTA :'( please help me brother . thank you very much

  10. Hello, im using a tencent one with ww rom installed. Can i just skip to step 3 ?
    And also my phone is currently on 16.031.1908.12, do you habe the boot inage for that ?

    1. Hi Andro. I would still suggest following from step #1 to ensure that the firmware doesn’t have any other trace of CN firmware.

      As for the firmware to use, you can use the latest one “WW-17-0240.2004.9”. In flashing this, your phone will automatically be updated to the most recent WW firmware.

  11. Hello! I did Steps 1 ~ 5 [Firmware: WW-16.0631.1910.64: / WW-16.0631.1910.64 Patched Boot Image / WW-16.0631.1910.64 Stock Boot Image ] but after step 5.7, the system said ” Slot_b is unbeatable, error verifying image” Is there a way for me to troubleshoot this? I thank you for taking the time to handle my concern.

    1. Hello. After locking the bootloader, you might have to perform a factory data reset via the stock recovery before you can boot into the system (OS).

      What caught my eye is the error it shows about the slot being unreachable. That’s not common.

      Just to confirm, you did flash the stock boot image, right? And when you flashed it, to which slot did it write to?

  12. The application to unlock boot loader fails with “Unknown Error” looks like ASUS rejects the request

    1. Hi Milind. Is your ROG Phone 2 running Android 10 or Android Pie? Also, which unlock app did you download exactly?

  13. Buen dia Dhananjay tengo un telefono rog phone 2 tecent games que ya esta con una version global la cual es : ww_16.0631.1910.44_0 quiero actualizar a android 10 baje este firware : UL-ASUS_I001_1-ASUS-17.0230.2004.60-1.1.162-user.zip pero al queres instalar me sale fallo de instalacion por favor si me pueden ayudar gracias .

    1. Hello Carlos. Please download and install the Device Info HW app from the Play Store on your phone. Once installed, launch the application and go to the ‘System’ tab. Then check and report the exact information you see right in front of “Fingerprint”.

    2. Thank you very much for your help. You are a master in telephone software, I want to congratulate you for the personalized attention and for your interest in us.

    3. You’re most welcome, Carlos! If you have got any further questions, please feel free to reach back to me.

  14. Hello Dhannanjay

I can not shut it down or enter the fastboot mode. and i m a compleate noob . is there anything u can help me with?
    thanks in advance
    Rolin

    1. Hi Rolin, was the firmware flash successful and your phone booted automatically?

      If so, then please power off your phone by holding the Power button for about 10 seconds. As soon as the screen turns off, quickly hold the Volume Up and Power buttons together. This will boot your ROG Phone 2 into Fastboot Mode.

      In Fastboot Mode, tap either of the Volume buttons until you see “Recovery mode” in red color highlighted on the top of the screen. Then press the Power button to confirm and boot your phone into the stock recovery.

      After your phone gets into the stock recovery mode, you have to perform a factory data reset. To do this, use the Volume keys to move the selector to “Wipe data/factory reset” and press the Power button to confirm the selection.

      After performing the factory reset, select ‘Reboot system now’ in the stock recovery. This should boot your phone into the OS.

    2. hola un favor instale el gestor de arranque como esta en el paso uno se me reinicio todo el telefono de fabrica , pero no entra a fast boot ayuda por favor

  15. HI, I Received my tencent CN version already converted to global rom android 9. However in safety net it says CTS profile match: failed.
    Please what steps do I need to follow to correctly upgrade to the android 10 firmware. I would really appreciate your help.

    1. Hi Bola. CTS profile will not pass anymore because Google has implemented hardware-based attestation for SafetyNet. So, there’s no possible way to pass it anymore. The same was informed by Magisk developer topjohnwu on this Twitter handle.

      For upgrading to Android 10, you will need to download the latest Android 10 full firmware zip from here and follow the provided instructions in the same post to install it. Make sure that you download and use the WW Android 10 ROM, not the CN one.

  16. Hy ,, Is it necessary to open the bootloader before installing firmware file of the latest WW-17.0230.2004.60 (Android 10-based April 2020 security update) ? Because my firmware lock to ww rom 9 pie . I’m user ROG phone Tencent.

    I help u answer ?

    1. Hi. Have you already converted on Recent ROG phone 2 to Global edition previously?

    2. Yeah ,, i’m convert with Flash EDL mode and now my Rom/fingerprint WW ( Global Rom) . I’m running in android 9 WW.16.0631.1910.35_0 lock bootloader.
      Is it necessary to open the bootloader before installing firmware file of the latest WW-17.0230.2004.60 ??

    3. Hi again, Fandy. If you have properly converted your phone to WW edition earlier, then installing Android 10 update is really easy. Please visit this post, download the latest Android 10 full firmware and install it using the provided instructions.

      There’s no need to unlock the bootloader to install the update using the method provided in the post I have linked. But do keep in mind that it will ONLY WORK if you have PROPERLY CONVERTED TO WW GLOBAL EDITION.

  17. After holding power and volume i managed to get inside recovery mode. Then it erased things and now it works;)

    Now it works again.

    1. Hi Tom, after relocking the bootloader, it’s important to perform a factory reset. Normally, the system will prompt you automatically. If it doesn’t, it needs to be done manually, just like you did it.

    1. Hi again, Pete. Can you confirm which RAW firmware you installed and exactly which patched boot image did you use? Please mention the full filenames.

    2. Hi Dhananjay,

      I have Tencent edition and followed your steps for WW-17.0230.2004.60. however after rooting, i am unable to access the Wifi and UI keeps on freezing.

      Any solution for that?

    3. Hi Harry. That indicates using a boot image from a different software version. I checked the boot images and found that I upload the stock boot image for “WW-17.0210.2001.60” instead of “WW-17.0230.2004.60” (The RAW firmware file you used). I have uploaded the correct boot image and updated the link. Please download the one for “WW-17.0230.2004.60” and repeat step #3 and further.

      Sorry for the inconvenience.

    4. Thank you for the reply, I am able to perform the flash but unable to perform fastboot thing,

      it doesn’t list any devices on the prompt.

      Can you help me on this 🙂

    1. Hi Pete. That could be because the app couldn’t mount the system partition as R/W (Rewritable) properly. Please fore-close the app, then open it and try again. In some cases, people had to do that about 5-10 times to get it to work.

    2. Hello, I did what you explain and the same thing keeps happening. I can’t erase Hidden folder.

      Thans!

    3. Hi Franco. You will need to keep trying, it will be deleted. Close the app, restart the phone, try deleting, and if it doesn’t work then repeat the same.

      Or, you can try performing the steps from the start. That might help.

  18. hola, yo tengo la version ww_16.0631.1910.44_0. Que debo hacer para actualizar a android 10? necesito tu ayuda

  19. Soy de argentina. Cómo puedo hacer para que me ayudes más personalmente? Necesito enviarte capturas de pantalla. Gracias

    1. Hello Luis. If you need to share screenshots, please upload them to hosts like imgur[dot]com and share the link with me here.

  20. hi, im now in CN 2004.60. i want to flash WW but your version is 2001.60. is this ok to donwgrade to a previous version of android 10?

    1. Hi Pierce. Yes, there would be no problem in doing that. Once you have successfully converted the phone, you can install the latest WW-17.0230.2004.60 update (April 2020 update released on 12th May) through this post.

    2. No problem, Pierce. Please let me know if you have any more questions. Also, do let me know how the process goes.

    3. Hi, again Pierce. I have just added the links for the RAW firmware file of the latest WW-17.0230.2004.60 (Android 10-based April 2020 security update).

  21. Hello, I have unlocked the bootloader and flash Android 10 Raw firmware. After flashing, the phone is stuck on loading screen and I can not do anything. How to fix this? Thank

    1. Hi. Which ROM did you have installed prior to trying this? Also, which RAW firmware file did you use?

      One more thing, was the process shown as completed in the black-colored DOS window (The window that opened when you launched the ‘flashall_AFT.cmd’ file)?

    2. I have the same thing….keeps loading when i do the last steps of locking the bootloader (step 5)
      The update and all went great.

    3. Hi Peter. Please boot your phone into the stock recovery and perform a factory reset.
