Custom ROMs are an integral part of the developer community at XDA-Developers. These third-party firmwares provide an extended experience to the users and help them get the best from their devices. All these ROMs differ from each other in terms of their purpose. A few like LineageOS focus on intensive features and performance. While those like ParanoidAndroid and OmniROM are meant for extreme stability, along with a few added features.

The 5T has marked itself to be the fastest Android device to receive support for TWRP. But even then it wasn’t much of significance when you don’t have many chances to use it, except for rooting and installing mods like ViPER4Android.

Today, the users have got the chance to put TWRP into use and install OmniROM on OnePlus 5T. Up until now, only the Nexus and Pixel devices have had the privilege to enjoy Android 8.1 Oreo. But you can now experience the latest Android version on your OnePlus 5T too.

 

XDA Senior Member – darkobas has taken the time to compile OmniROM from the official sources. The team is already working out the code based on the “android-8.1.0_r1” tree. It seems like the developers will officially add support of for the OnePlus 5T, but there is still time before the ROM is available officially.
