[Xiaomi Mi A3 Questions & Answers] MrEuro:
Hey there,

first of all thank you for your reply :)

Unfortunately those steps were not working for me or i am misunderstanding something.

So i followed your steps:

1. Flash the latest Android 10 fastboot rom (search in XDA) - found that here https://xdaforums.com/mi-a3/how-to/fastboot-rom-android-10-v11-0-8-0-march-t4069077

Unzipped the files to my platform-tools folder and started the "flash_all.bat" file. No errors so far -> after the last command "fastboot reboot" device automatically booted up and it stucked on the "mi" logo. In the thread which i have mentioned above a few people had the same problem and they were told to execute an factory reset.

So i went back to fastbood mode and typed in "fastboot erase userdata" - but nothing happended. So i was stuck at the "mi" logo.

Then i thought i will go on and follow the next steps:

2. Download this modified boot image: - downloaded that

3. On fastboot, execute: fastboot getvar current-slot (make sure you are on slot A)

3. If not on A, execute: fastboot set_active a

4. Execute: fastboot flash boot (image name).img

5. Fastboot reboot (make sure to press volume + before hitting enter)

6. You are now booted to TWRP Endresult: NO TWRP was booting straight away back to fastboot mode

What am i doing wrong? I just want to go back to my Androis OS with latest March Security Patch and Install TWRP permanently,so after that i can root it with Magisk.

Edit# 1: I was not using your modified boot image, i took that one: https://xdaforums.com/showpost.php?p=82087765&postcount=3 and could boot into TWRP after that.

But anyways it seems that there is nothing on my phone, i still stuck at the "mi" logo and when i go to TWRP, everything is empty on the storage device. I mean if i go to the Button "Wipe" --> "then Swipe for factory reset" i get the following errors.

"Could not mount /data and unable to find crypto footer."

"unable to mount storage"

Current state of the device:

Booting normally: Stucks on "Mi" Logo

Holding Volume Down + Power: boots to "FastBoot Mode"

Holding Volume Up + Power: boots to "TWRP"

Edit# 2: Phone is alive again :)

Followed these steps below and managed to install TWRP permanently and get back my Android OS.

If you have fastboot, simply flash TWRP, boot to TWRP recovery, do a full wipe, including formatting using data. Reboot to TWRP ( check boxes to install TWRP manager - if you see that screen)

Once rebooted to TWRP Recovery, Flash Rom of Choice, Gapps if needed, Flash Magisk again. Boot to system and setup.

The only issue i am having at the moment, everytime i Install the Magisk.zip over TWRP my A3 stucks at "mi" logo. So just need to figure that out.

But hey i´m almost done! :D

Edit# 3: Tried to install Disable_Dm-Verity_ForceEncrypt package, before Magiskv20.4 installation, but still getting bootloop after flashing the .zip file.

Final Update: Everything is working :) Oh god, that was my first day with an Android Phone and i really learned a lot about it. Even if i figured out everything by myself, i hope that this thread helps someone out, who is facing similiar issues.

Final Steps:

1. downloaded MiFlash and flashed my Mi A3 with the latest ROM - laurel_sprout_global_images_V11.0.8.0.QFQMIXM_79d650b0da_10.0 -

2. Device booted up with an error that the Android OS is corrupted and i had to reset it to factory settings

3. Device booted up to the Android OS.

4. Downloaded my stock boot.img and copied that to my Downloads folder

5. Installed Magisk Manager on my device and patched my stock boot image. If everything is done an new magisk_patched.img will be created under the same path.

6.Used following command to copy the .img file from my device to my PC "adb pull /sdcard/Download/magisk_patched.img"

7. Opened CMD --> navigated to my adb tools and typed in following code: adb reboot bootloader --> Enter --> fastboot flash boot magisk_patched.img --> Enter --> fastboot continue

8. Done, device booted up and Magisk was successfully installed.

Thank you. ;)
