I suggest you to make a backup before to format Data.

DO NOT reboot your device onto System !

Consideration about "Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip" :

Many thanks to @Zackptg5 for this zip.
This zip disable Dm-Verity, Forced Encryption, and Disc Quota Disabler.
Like Zackptg5 says :
"This zip should be flashed after anything that modifies your boot img (like a custom kernel) but before magisk/supersu since this zip creates the files that tells magisk/supersu to not encrypt".

27) Tap on Magisk.zip
28) Tap on Busybox.zip
29) Swipe to confirm Flash.
30) Tap on Reboot (into System) and tap on Do Not Install.
31) Be patient.
32) Set up as new.

EXTREMELY VITAL :

Which A3 pro are these roms for?

A3 pro comes in two versions. Build number with an N and build number without an N. For which build number are these roms for? Thank you dev for your work!

TWRP 3.3.1 For 8.1 N 1.4_20190425?

Would it be a big effort to adapt TWRP 3.3.1 for N1.4_20190425?
Unfortunately, 3.2.3 is unable to decrypt > 8.0, so at the moment either run unencrypted or lose Nandroid :(
On the other hand, is it worth downgrading to V1.3_20190304? Whats the difference between 1.3 and 1.4?


UPDATE - NEW TWRP 3.3.1-0

Hi @Cleopatra Bianchi
Thank you for your work. Unfortunately, there is no lite version for A3_Pro V1.4 (N version) Android 8.1
However, could you list the apps safe to freeze and then safe to remove
The comparative screenshots of RAM memory usage (stock version vs. lite version) are really impressive :cool:
I started slowly with the easiest ones: Google music, Google Movies, Google drive etc ... But it quickly becomes tricky for me :p

Good News :D
UMIDIGI_A3_Pro_N_V1.2_20190910 .zip
Original Post from Russia
I don't speak russian. Here is what the translation of the end of the Russian tutorial (description section) gives: A little cleaned of garbage, twrp. magisk. [Немного почищена от мусора,twrp. magisk.]
Maybe I'm wrong, I guess the dev has cleaned some bloatwares from the original rom.
Have you noticed that?

I just installed it also

I have the firmware installed on my android 8.1 mobile phone, except for the finger sensor, the firmware works great, twrp and supersu are included. just flashing by SPF

You gave me the nerve to install it also and it really works good. I never use the fingerprint scanner and so I do not miss it. Everything installed perfect and the phone is faster and smoother.

This is how the phone should be. At least for me it is perfect now...
