UMIDIGI A5 Pro

UMIDIGI A5 Pro

Helio P23 (MT6763V)

Works pretty good. Some issues here and there, some missing features, but mostly usable day-to-day.

Steps to install

Three possibilities :

Install using TWRP or PBRP (Doesn't require unlock) [RECOMMENDED]

1. Install TWRP or Install PBRP into recovery using SPFT method
2. Boot into TWRP : Shut down the phone, press power + vol up. It will bring a menu, you can navigate using vol+ and select using vol-
3. Use "install image" to install system.img into system
4. Use install image to install vendor_treble_encryptable_a5PRO.img into vendor
5. Clear data partition in TWRP

Install using SPFT (Doesn't require bootloader unlock)

1. Download SP Flash Tool
2. You'll also need the stock ROM for it's scatter file (maps areas in the phone's eMMC)
3. Run SPFT, Download tab, select the scatter file, untick everything except system, vendor_1.4_treble_encryptable_a5PRO and userdata (userdata will format data partition) and on the right, you can click on the path to choose the correct GSI instead of the stock ROM's system.img .
4. Press Download an plug your phone which in powered down state (not booted, not in recovery).

Install using fastboot

Unrecommended, shorter to do, but requires a bootloader unlock. [Needs documentation !]

Recommended mods

If you choose to format data, before first boot of the GSI, you might want to install disable-forceencrypt-treble to be able to access data with TWRP. Link to it (flashable .zip in TWRP)

You can install Magisk if wanted https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
