Hi guys,

I unlocked my bootloader and flashed latest Xiaomi.eu 21.3.31on my Mi11.

I have to send pack the phone and want to flash stock rom and re-lock bootloader.

Can you explain me how can I do this? What about anti-version check?

I download latest venus_eea_global_images.

Thanks,

Davide

After you have flashed to original stock rom, you will have to re-lock your bootloader in fastboot mode.
In windows via commandline type:

"fastboot oem lock"

The smartphone will then reset to factory settings and your bootloader is locked again.
I've done that yesterday with my Redmi Note 10 Pro.

If I use xiaomi flash tool I can flash and lock together.

which tool/rom you used? no issue with anti rollback protection?

I flashed original EU rom from Mi download website for RN10P with TWRP (unofficial for sweet) installation via TF Card. Then tiped the Fastboot command in cmd, rebooted to Fastboot and it worked for me. Sorry I dont know how to flash with xiaomi flash tool. :( No issues with anti rollback protection during lock nor after.

Mi 11 does not have TWRP :-(

So, we have a common understanding we can transform a C device into a G one by flashing global Rom and re-lock the Bootloader?

Im going to try that in 2 weeks, edl rescue remains an option if i fail, right?

Dont know if this will work. My device is EU, I flashed Xiaomi.eu and tried official Global, too and then back to EU where I locked the bootloader again. Dont know if it is possible to lock the BL in another Rom.

Usually in typical fashion you can still unlock your device if you're flashing stock rom and lock your bootloader in GLOBAL ROM on CHINA SET device using Mi Unlock Tools. It still remember that the devices is bound to your Mi Account that you're registered in the developer option and theoretically you can unlock the device's bootloader back.

Why does it not connect to 5g? Is this something common? What model are you using?

I have the same issue with the eu rom and the Mi 10 ultra. I'll hold off when my Mi 11 Ultra arrives!

Have you tried the official Global and EEA roms to see if 5G works?

So, I'm still puzzled whether I brick my M2011K2C after flashing global Rom if I re-lock the Bootloader...

Does someone know for sure it's working?

Eu stable would be another option but I don't feel good passing it on with custom FW..

Internet says don't relock Chinese device if using global.. Damned, please assist..

I don't think you can lock the bootloader with anything other than the stock firmware it came with.

Download the stock rom of your phone (e.g. China or EU or etc..) and everything will be ok.
