Hello,
I have a mi8 bought at GeekBuying. It had a open bootloader and a "Global Rom". I tried to update to the eu Rom. Now I have a bootloader locked and the phone only goes into safe mode and fastboot mode. I tried to go back to the official Chinese firmware which did not work as the phone is bootlocked. Also can not do the unlock process using the Xiaomi homepage as I can not access the dev settings...
Any suggestions? Send back to China?
How is it possible to lock the bootloader? Did u use fastboot lock bootloader? Or using Mi flash?
Normal u can flash Xiaomi.eu rom without a problem with a unlocked bootloader it isn't possible to lock a bootloader by flash the eu rom in Twrp.
By the way, I never and I mean never seen so much ppl with bricked phones.

I used fastboot flash. With the official unzipped Rom from the official site. There was also no option to lock or unlock. Old rom had unlocked written on the bootscreen, now shows nothing about it anymore?
Maybe has to to do with a modified firmware by the shop I bought? I myself did not unlock the phone... Came like this.
I bought it also from Geekbuying. I told them that I want to sent it back, cause the box was not a new one, the box was not sealed and the boot loader was unlocked. I have also a bricked phone and I can't use Mi unlock since my account is not bound to this phone.
i bought a mi 9 lite and it came with the russian rom.
I wanted to unlock the bootloader and install the official globlal ROM with mi flash. can i lock the bootloader again with me flash when i install an official global rom?
or
is there a guide to install a global rom without unlocking the bootloader? and without using tools?
You need to first unlock your bootloader in order to fastboot flash the global rom (using MiFlash). After that in the MiFlash tool there is an option to "Flash all and lock" which will lock your bootloader again. Unfortunately there is not a way of doing it to my knowledge without unlocking your bootloader.
Here's the official guide here: https://c.mi.com/oc/miuidownload/detail?guide=2
Never, ever re-lock your bootloader as this will result in a hard brick that can only be resolved with EDL/authorized account!

Not to my knowledge. I have done it before with my device. Sure if you want to use custom roms/recoveries you will need to unlock your bootloader again which you can do if you are using an authorised account. However, if you are really worried about this happening, you might as well just keep your bootloader unlocked.
I bought a mi cc9 lite that came with a russian rom.
Before i could unlock my device, i was able to flash a global rom with a non official tool which name i can't remember.
Global rom was the only one i was able to flash. So yes it's possible.
ok
On which ROM and Device you CAN and CAN'T Lock Bootloader!

Hello

I think the most important acronym in the firmware. EU. Flashing the RKBEUXM should therefore not be a problem. Even without the bootloader unlock. OR only means that provider-specific functions are built in. If you don't know them or are unimportant, the XM works just as well.

If you had to unlock the bootloader to flash the XM, I wouldn't relock again. That would surely lead to a brick.

Hello! Can you tell me what method you used to do it? I have a Mi 11 lite 5G, the ROM that came from the factory was a Vodafone EU and I changed it for a Global EU ROM, specifically this one: renoir_eea_global_images_V12.0.8.0.RKIEUXM, but in the process with My Flash Tool the bootloader had to be open, now I have this ROM working perfectly, but I want to close the bootloader to use Google Pay etc. So I am very interested in your method to achieve it.

Don't relock your bootloader with EU rom. Your chinese phone will be bricked.
I am on MIUI 12.5.1.0.RJOINXM. My bootloader is locked. I don't have prior experience in flashing roms. Please help me to downgrade to MIUI 12.0.8. Thank you
No way. You must unlock bootloader then flash the older version with official Mi flash tool.
You can downgrade to any version using spflashtool easily, securely and safely.

Oh, okay.
If you flash in DOWNLOAD MODE, bootloader will keeps SAME, locked or unlocked.
If you flash in FIRMWARE UPGRADE MODE, bootloader will be LOCKED again.
If you flash in FORMAT ALL MODE, bootloader will be LOCKED again and you will lose all identications of the device like IMEI, BLUETOOTH MAC, WIFI MAC.
You can downgrade MIUI safely and securely using download mode.
Thank you, but what is DOWNLOAD MODE?

Dear VD171, i've just downgraded using MiFlashToolV2. The process was simple and the bootloader is still unlocked, so far so good.
But now it refuses to boot to system. It keeps restarting and shows the initial "Redmi", with the unlocked icon in the top.
I tried to Wipe data in xiamoi recovery, but the result is the same.
Please advice
