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

30) Tap on Reboot (into System) and tap on Do Not Install.
31) Be patient.

33) Tap on Settings --> System --> About phone
34) Tap seven times on Build number
35) Then, tap on Developer options.

Following the OP directions, got the update, v1.3, installed.
Steps:
1. Restore stock (v1.2) recovery using SPFlash Tool.
2. Boot to ROM, take OTA update
3. Boot to ROM.
4. Install TWRP (A3_P-NEW-twrp_04.rar).
5. Boot into Recovery (TWRP), install Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip, then Magisk 18.1 and Busybox).
6. Reboot system.
Done. :good:
Thank you, again, @cleopatra_Bianchi for all your efforts.

Anyone...

Anyone having issues with Magisk and the new 304 ROM? Magisk stops working and I have to reboot the phone to get it to respond no more than two times and it stops working again.

Actually I am not sure if it is Magisk and or simply the ROM has issues after using it for a few days? It seems that I have had the same issue (slowing down and no Magisk or TWRP at all installed) after a few days with a non-rooted ROM...

Just wondering. I have tried a dozen times and tried different ways to set everything up, no help, so I keep going back to the light ROM...

No, I do not have a problem with Magisk on the 304 ROM. Are you using the latest version of Magisk (18.1) with the correct recovery? Maybe re-trace your steps installing it... Other than that, I have no other suggestion, sorry.
The phone is working as it should, here, no issues whatsoever. And based on the lack of activity in this sub, I guess that's is the case for just about everybody else...

is there any custom rom for A3 PRO?

Kylesvet · May 2, 2019

None except the light ROM in this thread...

I consider the Light ROM custom as it has been modified to a point and very easy to install. But as far as something like LineageOS or so, not that I can find and I have looked long and hard. Project Treble is being somewhat promoted by 4PDA with the A3 Pro and I am getting ready to try that. They have half a dozen ROM's to use...

I was also hoping that someone would build a custom ROM for this phone...

Project Treble still confuses me...

But then that is not a hard thing to do...

I am using a v1.4

WelldonePL · May 10, 2019

Hi guys!
First of all, thanks OP for this thread!

I wanted to root my device, but I'm on v1.4 rom. So have I downgrade to stock v1.2? And then install OTA again to 1.4 and after that TWRP?
Sorry for noob q

Hi,

Umidigi has produced two different models of A3 Pro.
I mean, an A3 Pro without N letter (inside Build number) and an A3 Pro with N letter.
If your A3 Pro contains the v1.4 rom, it means that you own an A3 pro with N letter.
It is because Umidigi has released the 1.4 firmware only for the A3 pro with N letter.

Take a look at the following post :
https://xdaforums.com/showpost.php?p=78876483&postcount=54

For your information, you can NOT install any OTA updates when your phone is rooted.

I own an A3 Pro without N letter.
However, I will try to make a twrp recovery reserved exclusively for 1.4 N letter firmware (as soon as possible).

Regards

Grazie mille amico, grazie!

Cleopatra Bianchi · May 18, 2019

Hi Enrico9800,

Umidigi really did tell you about Pie firmware for A3 Pro ?
They really did tell you that they do not know when it happens ?
This is good news for all owners of this device.
Then, we look forward to see a Pie firmware posted onto Umidigi official website.

Hi, I did root my phone on the 1.4 version. Thanks for the guide! Unfortunately, later I made a mess in the system so I wanted to do a new installation. I forgot to mark
enable OEM unlocking & USB debugging and I did format via recovery. Now the system is not loading, but I can enter the recovery TWRP. How to restore the system? Can I copy the original ROM to the SD card and upload it via recovery? Greetings!

You have to mark OEM unlocking & USB debugging before to install the twrp recovery.
I suggest you to flash once again the stock firmware via SP Flash Tool.
Then, to flash once again the twrp recovery.

WelldonePL · May 22, 2019

Thank You Cleo

Can I flash via SP Flash Tool without enabling OEM unlocking & USB debugging? Because I can't boot phone right now to mark those options

Miko36110 · May 22, 2019

I just ordered the phone! arriving in a few hours
can't wait to flash the Light Rom you built!
