Hello!
Just received my Umidigi A3 - MT6739.
Firmware is Android 9, latest release: N Android 9.0 V1.3_20190610 ROM
I would like to flash a custom recovery (TWRP) and flash a custom ROM - like Lineage OS or Stock Android.
This is not the first time I root and flash an android device, however I am having difficulties finding the right files.
I tried to install custom TWRP recovery both through ADB tool and with SP flash tool.
I initially unlocked the OEM and bootloader using ADB tools, then I tried to flash a TWRP recovery image I found online but it turned out to be for Android 8.1 and not Android 9.
The phone switches on and boots normally - however I still don't have a custom recovery nor the possibility to install a custom ROM.
Here's a list of threads I already looked at and tested:

Did anyone who has the same phone manage to do such?
Thanks!
A3 TWRP Recovery
Hi,
It sounds like you have tried all the available options and since I have Android 8.1 mine is not the same. I can tell you that just in case you haven't seen this page yet, it may help, as it worked perfectly for me.

I found some TWRP for that mobile, and inserting a GSI ROM is easy, I have everything in my telegram group t.me/umidigi_es
All GSi I have tested are running into bootloop. Does anyone has get GSI or any Android9 or 10 custom rom running on A3 ?

Hey guys, I'm trying to install LineageOS GSI (arm64 A/B) on my Mi A3 and seem to be having some trouble getting the GSI to actually boot successfully.
I have already done my research both on XDA and elsewhere online, yet most threads focused on the device seem to be of little to no use and/or filled with spam replies that only serve to confuse people looking into this.
A quick note regarding the aforementioned threads:
I don't mean to sound disrespectful to the community, but honestly, bashing somebody over why they'd rather install anything but your own fav piece of software is completely ridiculous.
Without further ado, my case goes as follows:
I'm starting fresh with the latest stock firmware, after having unlocked my bootloader ofc (critical too), I've successfully installed TWRP, wiped, installed the system image and yet after rebooting I'm just greeted with good ol' Fastboot, at which point I either directly flash the stock firmware and try again or wipe my data and whatnot (through TWRP, if reinstalled) and still end up with Fastboot.
Therefore, I have to ask you guys:
Has anyone previously successfully installed any GSI rom on the Mi A3?
Did you flash the system img while on stock firmware or a previously flashed custom rom (ie Pixel Experience)?
Is there any need for any special patch similar to the ones used for MIUI based Xiaomi phones?
Did you face any other issues while trying to flash a GSI?
My intention is to eventually install microG using Nanodroid.
Thanks for asking. I was trying to flash Havoc, crDroid and MSM-Xtended Android 10 GSIs but I can't boot the phone.
I have flashed lots of GSIs in the past, but this is really intriguing me, I can't boot on Mi A3. Wiping or formatting data does not solve, neither Permissiver or Disable Dm-verity zips did the job... :crying:
I successfully bootet the LineageOS GSI yesterday. I was not coming from stock though. I think this process should work assuming you already bootet to TWRP:
1. flash the GSI image to system partition using TWRP
2. flash the TWRP installer to keep your recovery
3. (not sure if needed) flash no fde patch
4. optional: flash some other stuff like Magisk and gapps
5. wipe data and dalvik
I think it rebooted to recovery on my first try but worked after flashing everything again. I probably made some mistake on my first attempt but just make sure to try again before giving up.
Also there's this tutorial but it's not at all what I did to get it working:

Hi all, my first post here.
I recently bought this phone thinking it was customizable. Every tutorial I have tried has failed and required a re-flash to stock ROM using MIFlash.
I have tried custom ROMs, GSI ROMs, 64 bit, 32 bit, etc. I tried using Magisk 21.0 to root, it appears to work, but I believe the boot.img patching isn't currently working on this particular phone.
Most tutorials I have tried are very simple and use TWRP to flash the OS img file, then reboot and enjoy. Some suggest flashing vbmeta.img to prevent boot loop, but, boot loop happens anyway. I have TWRP installed and working, so far, that is all I have had success with.
Can this phone still be customized at all?
Update: I achieved root on the stock ROM. If anyone is interested I'll post the exact instructions.

Your bootloader needs to be unlocked and USB debugging enabled first of course. TWRP Recovery should be installed.
To do this, you need the adb and fastboot binaries installed on a PC/Laptop. I use Ubuntu and installing these is trivial via apt package manager:
Debian based:
Code:
sudo apt install adb fastboot
RedHat based:
Code:
yum install adb fastboot
If you use Windows, the install and use of these binaries is a little different. I don't use Windows so you'll have to do a quick search to find out how to install and use these binaries. The commands listed below will work no matter what OS you use.
Connect your phone to your PC/Laptop via it's USB cable and reboot it to TWRP Recovery:
Power off the phone, then power on while holding the volume up button until you see the TWRP logo. Log into TWRP to decrypt.
Next, you need to pull the current boot.img from your ROM to patch it for root access:
Code:
adb shell dd if=/dev/block/by-name/boot of=/sdcard/boot.img
There should be a boot.img on your phone's internal storage, copy it to your PC/Laptop. From TWRP, reboot your phone to fastboot.
Now, we'll use this most excellent, free resource to patch the boot.img file which will give root access:
https://patcher.yaalex.xyz/
Check the 'Include Magisk' checkbox on the website before submitting image.
Important: After you upload your boot.img file to the website, be patient. This could take 10 minutes or more to complete, just wait until you get a prompt to download the patched image. You will be provided a patched_boot.img file from the website once it is finished.
Finally, all you need to do is flash the patched_boot.img to your phone:
Code:
fastboot flash boot patched_boot.img
Boot your phone to the ROM:
Code:
fastboot reboot
Install Magisk Manager if you haven't already, and enable Magisk Hide in the settings. Magisk Manager should report root access is available and SafetyNet test should pass.
I typed all this up from memory so if you run into trouble or are confused by any step, let me know and I will gladly clarify/fix the steps.
I hope this helps others achieve root on this phone. Let me know how it goes and happy de-bloating!
Rollback instructions:
If your phone fails to boot don't panic. You can restore your original boot.img if needed to regain access. Reboot your phone to fastboot:
Boot phone while holding the down volume button until you see the fastboot logo.
Next, flash the original boot.img to the boot partition:
Code:
fastboot flash boot boot.img
Now just reboot to ROM and all should be restored:
Code:
fastboot reboot

Iirc redmi 8a is an ab device, and yes this device is as customisable as any other Qualcomm. What gsi image are you flashing?
Actually he is not way off ..... i am NOT able to find a Custom Non MIUI ROM with full VoLTE support. VoLTE fix for GSI's ( if at all it worked ! ) does not work for Havoc. twrp root is all good. I want a NON MIUI ROM that can regional variants ( Europe and Asia ) and supports VoLTE
I recently flashed linage os 18.1 on my Xperia TX (Hayabusa). my problem is I can't flash gapps with TWRP (and stock linage recovery). I can't flash magisk and I can't flash any of those with sideload.
root access is only available for adb.
is there anyway to install gapps with adb only or somehow flash magisk?
(I know this device is from stone age. I even got a newer phone but I need this device too)
I've tried both a patched recovery with fastbootd as well as the recently released unofficial TWRP and have had no luck flashing any GSI with the device just restarting before it enters the GSI boot animation. Has anyone has any luck?
