Xiaomi Mi A1 - Rollback to Stock 8.1 HELP! - Xiaomi Mi A1 Questions & Answers

Hello first of all sorry for my bad english,
I update to Android Pie (From Netherlands VPN) and works fine but when i tried to install stock rom 8.1 with Mi Flash Tool my phone freezes, when i tried to flash the Nougat official firmware from Mi Flash tool my SIM CARD IS LOCKED, the only way to get my phone working is Android Pie BETA via Fastboot. What i need to do to bring my phone to stable stock rom 8.1 ?

I saw a tutorial with someone said to flash the nougat with EDL but i dont know what EDL is...

Mate, I'm going to say this just once. Please search for your question BEFORE posting a duplicate.

Sorry for that mate, but i am a bit confused and i dont know what can i do to rollback official to stock OREO, because i am on Android Pie BETA

Have you turned on the OEM unlock option? If not, just search for "fastboot oem unlock" command

Maybe the pie rom has ARB and cannot rollback easily.

So i need to flash the Stock ROM via EDL mode and then flash it with Mi Flash Tool?

What have you done? eager to update to pie and you experience bug and want to roll back? that's just a douchebag move imo.

Flashing original firmware

Hi, Can somebody tell me if its necessary to unlock the bootloader before flashing the official firmware. My device is not rooted and has a locked bootloader but as I wanted to flash the original firmware to refresh it, I was wondering if I can do it without unlocking the bootloader.
Thanks in advance.
Check this thread for EDL Mode https://forum.xda-developers.com/an.../guide-how-to-reboot-to-edl-fastboot-t3394292. Reboot to EDL Mode and flash using MI Flash Tool. This flashing not reuqires bootloader unlock.

Sorry but that is not correct, the A1 uses just fastboot, we don't use EDL.
Anyway just follow this guide

You just need to install miFlash or use fastboot commands if your more advanced, reboot to bootloader

Bootloop, stock Pie fastboot image needed.

Hi there, let me explain...
I f*ckup re-installing the latest Oreo stock fastboot image onto my Lineage 16 December firmware, and guess what, without paying attention I choose "Flash all and lock".
So now I am bootlooping, I cannot flash anything (twrp/rom or other) through fastboot.
I can EDL flash, but since December Pie beta brought us rollback protection, flashing the latest stock Oreo fastboot with EDL image won't fix my problem.
I guess my one and only solution is to flash a Pie Fastboot image through edl. I tried with this one (https://www.theandroidsoul.com/how-to-download-mi-a1-android-pie-update/) but unfortunately mi flash tool gives my this error: "programmer file not found", I looked into the " flash_all.bat provided" and everything look fine...
So I am seeking you help. And maybe someone over here might be able to provide me a stock pie fastboot image?
Thanks in advance, cheers
I also faced this problem bro!!!
I enterd in fastboot mode and boot into twrp recovery then flashed only linegeOs 15.1 that means 8.1 then my mobile boots into system ?
i was also searching for pie fastboot image,,, but right now its not availabe,, so can you try this.. i am also using this pie https://forum.xda-developers.com/mi-a1/development/twrp-stock-8-1-0-t3856328
@Manojyaligar @taran181
Thanks for replying, my problem is I cannot flash anything through Fastboot as my phone's bootloader is actually locked.
So the only way I have to flash anything is through EDL, and I don't think that you can boot into TWRP from EDL.

You can try flashing a nougat fastboot image. That might allow you to boot up and enable unlocking the bootloader.

I had to downgrade to nougat, and write back imei on nvram.

MI 9T soft bricked, how to go back to Global Stable

After install to EU dev. 9.7.18
NO recovery more and no access to the System, only bootloop, just Soft bricked my phone.
So I decided to install into fastboot mode the global stable 10.3.6 tgz and modified the anti rollback error.

If your device is 1 (anti rollback enabled) the TGZ rom must be 1 or major.
Open flash-all.bat in a text editor like Notepad++ and look for the following line: set CURRENT_ANTI_VER=#
That number (#) is the rollback index of the MIUI version you want to flash. If that number is equal to or greater than your current rollback index, then it’s safe to flash in TWRP, Mi Flash, etc. If that number is less than your current rollback index

Friend, I also have the same question ... Is something concrete modified? My software was the global version 10.3.9 and now I can not repair with the fastboot version 10.3.6 ...
What I can do?
How did you solve it?
I did something different, easier in my opinion:
• Downloaded a fastboot rom and uncompress it
• extracted the files: system.img, recovery.img and boot.img
• Flashed them with CMD/Terminal
• Erased data
• Rebooted

I was on Developer beta, bootlooping without recovery, Only fastboot continue was working
I flashed this fastboot rom from the OP https://mifirm.net/model/davinci.ttt#fb-mif
Download fastboot rom > Extract > use Miflash( Download here https://www.xiaomiflash.com/download/ ) > flash Fastboot rom
I have mi9t and i use OSX, dont have windows. when installing xeu dev 9.7.18 twrp gone, i downloaded 10.3.6 stable global fastboot rom. i unpack rom and edited flash_all file as in osx comad for fastboot is not as on windows in os x is ./fastboot
so in any fastboot writen on flash_all i had to put prefix ./ and in terminal i flash fastboot rom, no problems about antiroll back.
Any way on how to change the Region? it got locked to China
solved by flashing cust.img

There is no anti roll-back in our phone. You can safely flash everything for our davinci I think. I flashed 10.3.7.0 and all was working fine.

relock bootloader

I have Mi 9T Global version Rom ; i unlocked the bootloader and flash Rom EEA european
all work fine now i need help relockin bootloader
If you relock your bootloader, it will format all your data.
You only have to type this fastboot command:
Code:
fastboot oem lock
And if the phone doesn't reboot itself:
Code:
fastboot reboot
