Here is the recommended recovery build, a fork from TWRP, which is highly recommended to flash custom Android ROMs such as AEX. This recovery has similar main function to its official build.
TWRP is basically a custom recovery developed by Team Win Developer Team. This custom recovery has been around years ago.
Its popularity among third-party Android developers and flashing maniacs proves itself as world’s best recovery.
Many Android devices have flashed TWRP. On top of that, there have been a number of its forked / customized variants.
Including the one available below.
This build is a customized version of TWRP by Atman.
This TWRP is necessary if you want to get AOSP Extended ROM (AEX) installed on your Xiaomi Redmi Note 7 Pro (codename Violet).
Redmi Note 7 Pro boasts Qualcomm SDM675 Snapdragon 675 SoC. This chipset sports Octa-core Kryo CPUs and Adreno 612 GPU. On top of that, the phone has a super awesome dual-camera setup.
It ships with MIUI 10 Android 9.0 Pie on board. MIUI is cool but this ROM may not satisfy flashing maniacs all over the world.
Anyway, it is better for you to download and use the twistloop TWRP if you want to flash AOSP Extended ROM on your Redmi Note 7 Pro.
Flashing the TWRP is similar to the way you flash any official builds of TWRP.
General rules apply: bootloader unlocked, USB debugging enabled, etc.
