poco m3 clean & lock bootloader after region change from global rom - POCO M3 Questions & Answers

is that true statement?
after converting global rom to any other region we can relock bootloader?
it is only not allowed to install a different region MIUI ROM on China devices, global devices do not have this limitation.

yesterday I installed the European version on my citrus that had the Global ROM. I didn't get to re-lock bootloader, but everything worked perfectly

Source from other forum (website) : China default firmware to other region or any global rom can't be re-lock and vice versa. But as long as not china rom, you can re-lock as you like. I tried with my EU rom by default and unlocked the boatloader then to Indonesia rom and re-lock it, done and worry no more.

You mean EU or xiaomi.eu ROM ?
If I understood well, CN version phones can't relock into any other region MIUI stock rom nor xiaomi.eu (even if it's CN-based).
But most OEM allow relocking into different firmware region(e.g. OnePlus allows changing EU, GLO & IN versions and relocking afterwards).

Does this global rom work in the chinese version of lavender?

Yes it does. I bought a Chinese version, waited for 15 days to unlock bootloader, then installed EU rom. You can choose to install official global but EU Global is an slightly improved version of the Global. Either one works fine.
I had no problem flashing the ROM. Just make sure you follow all the steps as explained.

Xiaomi EU is based in MIUI chinese version and comes with ARB disabled. It's not recommended to flash a global ROM in the chinese version because it could brick the device.

Change ROM from China to Global

Hello,
I just got a Redmi Note 7 Chinese variant but I live in India and the Chinese MIUI isn't that great. I want to change it to the global ROM. I have the fastboot ROM downloaded and even the recovery ROM. I'm hoping that someone has already addressed the issue but I'm posting this because I'm not able to find any. My phone is currently running MIUI China 10.2.13 and it has received the 10.3.4 update. I haven't updated it since it might increment the arb index. Can anyone give me a confirmed, safe and working method to change my software from China to Global? I understand the risks of bootloader unlocking and all.

Switch firmware from Russian to Global

Hi guys.
I am new in Xiaomi devices and a little confuse about region firmware, lock and unlock bootloader in Xiaomi phones.
My Mi 9T firmware is latest russian firmware (QFJRUXM) and bootloader locked now (I do unlock bootloader before, but re-locked and back to official FW)
Can i unlock bootloader again, install global firmware with MiFlash Tool, then re-lock bootloader?
I hear only relock after switch from china to global or reverse can break device. Is this true?

Using Global ROM - Can i lock bootloader and install EU rom?

1. lock bootloader
2. and install fastboot EU rom v12.0.7

No, you can't, because the locked bootloader will detect which ROM is installed, so if a different ROM is installed with locked bootloader, it will only boot into the recovery and show "This MIUI version can't be installed on this device" error, then you will need to unlock the bootloader again.
Edit: According to @Eam31961, you can relock the bootloader with a different region of ROM installed on M3. I have also tried it, it works.

To use it with unlocked bootloader, you can install Magisk, and make sure to use Magisk hide, and also hide the Magisk manager with a random pacakge name in Magisk's settings.

For me is different from your experience may be. My POCO M3 default ROM was JFEUXM which means EU Global Version then I switched to JFIDXM for Indonesian ROM with features of AutoCall Recording and Mi Message and bootloader reLocked and now it's Locked. With no problem.

Maybe POCO M3 is different, I didn't test a different region ROM on it.
Thank you for letting me know.
I got the error when I tried to install Indian ROM on my China version of Redmi 6 Pro.

Okay, bro, I got you. I read from another forum that accordingly, China ROM can't be re-lock to other Region ROM but you can revert back to China ROM and re-lock it.
I have now installed the Taiwan ROM (QJFTWXM) on my M3 which came with a global ROM (QJFMIXM), yes it works, I chose the option clean all and lock.
Now with the Taiwan ROM, I have MIUI dialer and message apps, call recording also works, and it does not have any issues.
Thank you @Eam31961 !
