Hey guys,
can someone tell me if it's possible to downgrade the stock android pie version to stock oreo without rooting my device or unlock the bootloader?
I read some threads and posts but i'm not sure, because the information is disputed.
So can i flash the old stock android without getting a brick or getting stuck in edl-mode?
Thank you for your answers

Hello,
I think that it's not possible without unlocking bootloader. The unique solution is to enter in edl-mode but this is more dangerous than unlock the bootloader. Unlock bootloader is very simple and not dangerous, you are just going to loose all of your data but with a backup this is not a problem.
Root is not necessary for that, if you need help to do your downgrade with bootloader unlocking tell me !
I'm here if you have any question or if you need help !

Flashing via EDL Mode only works with unlocked bootloader!
Unlock Bootloader will erasing all data (reset system)!

I don't now the link but I can explain you the process.
/!\ This will erase all of your data !!
1) Enable developer options by going to Settings > About Phone, scroll down to Build number and tap 5-7 times to enable developer option.
2) Once you enabled the Developer Options. Returned back to Settings > Developer Options > USB Debugging and OEM Unlock. Just Enable there options.
At that time you have 2 option, official option and non-official version.
- Official Version,
This method require some days because you have to ask xiaomi to send you an unlock code.
You need Windows it doesn't work on Linux.
1) Go to http://en.miui.com/unlock, click on Unlock button on the webpage now you have to login and then proceed to tap on Download Mi Unlock from the resulting page.
2) Now, proceed to put your Xiaomi Mi A2 Lite into Fastboot mode by powering it on while holding Volume Down and Power buttons simultaneously. Hold until you see your phone is booted into Fastboot mode.
3) After the successful login, the validation process will start on your phone, and for the first time, you will get a message that “You don’t have the permission to Unlock the device”
4) Now click on the “Go” button or use Go to MIUI Unlock page to receive the unlocking permission.
5) Now click on the Unlock Now and log in with your Mi account details and fill all details.
6) You will get OTP for confirmation use it to complete the process.
7) Now wait until your application gets approved, you will receive the OTP password on your phone number once it’s approved.
8) Now Open the Mi Flash tool click on unlock and pass the two pop-up. Your device will be unlocked
Non-Official but simple version :
1) Proceed to put your Xiaomi Mi A2 Lite into Fastboot mode by powering it on while holding Volume Down and Power buttons simultaneously. Hold until you see your phone is booted into Fastboot
mode.
4) Download Miniamal ADB and fastboot in you are on windows, https://forum.xda-developers.com/showthread.php?t=2317790
If you are on linux use
Code:
sudo apt-get install fastboot
Code:
sudo apt-get install adb
3) On Windows in Minimal ADB and fastboot or on Linux on the terminal enter this command
Code:
fastboot oem unlock
4) Your phone will reboot, it's unlock !
PS: Sorry for my bad English

Actually you could avoid the erasing data
When you get in to fastboot mode
hold to volume down button before and write "fastboot oem unlock" code
dont release until phone shows mi logo at the startup
i have a xiaomi note 5
[whyred] which I can only get fastboot I have tried to
flash with the latest MiFlash and the 28 may 2018 Miflash
can see the device - it goes through the flash and
everything seems to be doing fine until after 30 seconds it says error
:FAILED ( remote: Flashing is not allowed in Lock State )
im trying to flash in edl but need a mi account
And im forget my mi account
any ideas ?
You can Flash any Rom over ADB search in YouTube ??
Even if you flash rom it will ask you at beginning for mi account. You can easily recover the password by going on site and select a recover password and use the email that you were using before.
You need No Password you have to do it with ADB Fastboot and Flash a new Rom on your device??
My Mi A2 Lite suddenly do not boots. When it starts, the screens are: "Android One", Mi logo and "Shutting down".
It can access Recovery Mode and Fastboot.
THE PROBLEMS:
1) It has the bootloader locked
2) I am afraid it has no Mi account.
I have tried almost everything:
a) Mi unlock app ==> Couldn't unlock. Please add your account in MIUI's settings > Developer options > Mi unlock status
b) Mi Flash ==> error as bootloader is locked0
c) EDL mode: I have tried several times, but with no success. I think because bootloader is blocked.
d) Fastboot commands and systems answers.:
fastboot oem edl ==> FAILED (remote: device is locked! no edl)
fastboot oem unlock ==> FAILED (remote: oem unlock is not allowed)
The last thing I can try is the EDL cable, but I am afraid it will no work as it cannot access EDL mode with the locked bootloader.
Any ideas or alternative solutions?
Thanks indeed.
Try to change partition slot using adb
Search on how to do that on Google I hope it works
Finally I have flashed it trough EDl mode ==> even if you hace the bootloader locked, you can flash it through EDL mode

Bricked with a locked bootloader - "This MIUI version can't be installed on this device"
I can get to "adb sideload" and fastboot, but the bootloader is locked
Can I unlock the bootloader with EDL? Can I access EDL with an EDL-cable? Or do I need to open the phone and short the EDL pins?
Can I recover the phone from a Linux computer? Or do I need Windoze?
Is it even possible to un-screw this phone?
Any help appreciated.

1- Checking if this problem is still a problem with custom ROMs; it is, and thus I believe it to be a hardware fault.
2- Done testing, re-install stock stock ROM, lock bootloader via adb; bricked phone.

ok, you can run edl mode but its no good for you, its already locked by xiaomi, ( go ing to fastboot mode and give commands something like this " fastboot boot edl")
* do you see padlock lock sign when you go to fastboot mode
* try to flash vbmeta in fastboot mode
* try again to flash correct version miui fastboot rom with mi flashing tool with out selecting lock bootloader
I can get to fastboot by holding power+vol-down. There's no lock icon.
On Ubuntu, I don't think fastboot is compiled to support rebooting into edl. I tried editing the source, and I'm not sure if I did it right, but the binary I built did not boot the phone into edl.
Using these commands:
Code:
fastboot flash vbmeta /tmp/platform-tools/vbmeta.img
Code:
fastboot --disable-verity flash vbmeta /tmp/platform-tools/vbmeta.img
Code:
fastboot --disable-verity --disable-verification flash vbmeta /tmp/platform-tools/vbmeta.img
They all give the same result:
Code:
target reported max download size of 804274176 bytes
sending 'vbmeta' (4 KB)...
OKAY [ 0.006s]
writing 'vbmeta'...
FAILED (remote: Flashing is not allowed in Lock State)
finished. total time: 0.007s

1- That requires access to a working phone.
2- All I'm finding is instructions for how to type "fastboot oem unlock" on a Windoze computer.

Did you found a way to fix the phone or unlock bootloader?
You have 2 ways to get out of this situation.
1. Try to unlock the bootloader with the Mi account you used last time.
2. If couldn't unlock, then switch to EDL mode. Use a no auth programmer to flash the correct variant fastboot ROM and the device should boots up. Then add account again and wait for 168 hours for unlocking.
Since we've got no auth programmer for Sm6125 we could use EDL mode freely.
Hi there @go vegan , have you already fix your phone again? because i also got the same situation on my redmi 6. or is there anybody who can help? thanks
Hi all add me to the list with a k20pro.
The device was unlocked at the start, i got MIUI 12.5 global and flashed with miflashtool.
but wipe and lock was active.
now the phone comes up to the recovery menu and says the miui version is not for this device.
When I try to flash to another version, miflashtool says the device is locked,
when I try to unlock while using the account the device is registered in, miunlock says go to settings >developer options> mi unlock status.
Gave it to a repair shop for 1.5 months and nothing. I live in Iran so no authorized service centers here.
I have access to fast boot mode and recovery.
I tried xiaomitoll V2 which had a specific question asking if my device would show This MIUI version can't be installed on this device in phone is bricked option. It goes to get china official Rom but then errors.
I'm a noob here so any help would be great, tnx.
I have encountered the same problem a few hours ago with my beloved Redmi K20 Pro. My heart became gloomy thinking that I have no way left other than having to take to an authorized service centre where they will rip off the back cover. But then I stumbled upon this simple solution that took me a minute or two. This is how I solved it:
Entered the fastboot mode
Connected the phone to my laptop using the USB cable
Opened the official Mi Unlock Tool and logged in with my Mi account, and
Clicked on the beautiful UNLOCK button!
Boom! The phone is back to its vibrant life! I'm just happy again!

Apply for permissions to unlock Mi devices

The solution to the problem is simple.
into fast boot mode,
Run unlock again!! Obviously it's locked. When unlocking is executed,
the same screen may appear again. Please do a reboot. You will definitely see the MIUI installation screen.
Device: Redmi note 7S
I found a solution and it worked for me:
1.Download the bat file and execute in your windows pc : https://drive.google.com/file/d/1NqPotx06yRuhPsOdEAdS4JNsk7qWWchF/view
2. After that use the MI unlocker tool to unlock the device.
3, Use mi flasher to flash the Rom.
After the hours of research in the internet i found the solution.
Thanks

Install Minimal ADB & Fastboot, reboot your phone to fastboot if you can and then type "fastboot devices", if your phone is detected it should show then "fastboot continue", your phone should boot up to the version you had before
