Redmi Note 4 LineageOS 15.1 ROM with Project Treble Support
Android Oreo introduced Project Treble to represent a major re-architecture of the Android Framework. It has been introduced to facilitate easier and faster OS updates for Android devices. Google has been able to modularize the OS, by drawing a line between silicon/OEM code and the normal Android Framework. As a general rule of thumb, all devices shipping with Oreo out-of-the-box must support Project Treble. It not only affects the official firmware updates but also has a drastic effect on the custom ROM development scene. With added support, Treble-enabled devices will be eligible to install a generic ROM without having to wait for the OEM/Silicon manufacturer to update the dedicated drivers.
Now before you install Redmi Note 4 LineageOS 15.1 ROM, let us talk a bit more about how XDA senior member – abhishek987 was actually able to achieve this. According to Mishaal Rahman (XDA), the developer converted the unused ‘CUST’ partition to ‘Vendor’, which is approximately 830 MB in size. The partition originally contained stuff related to MIUI. But it had no significance on the AOSP-based build. With some help from phhusson, the lead developer of the phh-Treble project, abhishek987 was finally able to boot the ROM.
