Yes you can, you need to flash the fastboot version with MiFlash. Just make shure to keep the bootloader unlocked, because locking the bootloader on an other rom than the one that came on the phone will result in a brick.
In MiFlash in the right bottom corner you have a couple of options, you need to choose 'Clean all'.

You can try to use Mi Flash to install the fastboot ROM, but you need to choose "clean all", do not choose lock, the phone will not boot if the bootloader is locked and detects a ROM of a different region.

If it boots successfully after installing the official EEA ROM, you need to always keep the bootloader unlocked.


Edit: I have installed Taiwan ROM on my M3 that came with global ROM, using Mi Flash Tool, the phone still works after locking bootloader (clean all and lock).

So it is only not allowed to install a different region MIUI ROM on China devices, global devices do not have this limitation.

Yes, it is certified after locking bootloader.
Hello, so you went from a Global rom (MI) to a Taiwan rom (TW)? I personally have a Redmi Note 10 Pro (in version 12.0.6.0, RKFEUOR), and I would like to change to a version 12.5.4.0 in RKFEUXM.

Logically, I will be in the same region since I am going from an EEA (EU) rom to an EEA rom (also EU), I simply remove the overlay from my Orange operator by switching from RKFEUOR to RKFEUXM. Will it be a problem if I lock my bootloader by doing "Clean All and lock"? I would like to keep the certifications.

Thank you !

The phone should still work without problems after relocking bootloader with that option, and it will still pass the certification.

But to flash the fastboot ROM you will still need to unlock bootloader, you can't update it with the recovery ROM method since they are different versions (OR and XM).

Okay, so to recap: I unlock with Mi Flash Unlock (there is a week left), then I flash my ROM for my Redmi Note 10 Pro "12.5.4.0 RKFEUXM" with Mi Flash while selecting "Clean All and Lock" , and the flash should go smoothly with the bootloader locked again after reboot? In short, the only ones who are affected by this problem are the Chinese who would like to move to another region (MI, or EU, TW ...), or those of Russian origin too, I guess ?

Yes, that is correct, make sure that the file you download is the fastboot ROM in the tgz format, not the recovery ROM.

Then you need to extract the tgz file into a folder, make sure there is no space in the path of the folder, so it's better to extract it to C:\ or D:\ on the computer, then select that folder in Mi Flash.

To unlock bootloader, you need to use the latest version of Mi Unlock (version 5.5), because there is an older version of it that already does not work.

Yes, at least in my own experience, the problem only exists when installing the official global ROM (or another region of MIUI) on a phone (after Redmi Note 5) that came with China ROM pre-installed. The phone will not boot until the bootloader is unlocked again.

I have tried installing the global ROM on the China versions of both Redmi 4X and Redmi 6 Pro, on Redmi 4X, I could lock the bootloader with global ROM installed and it would still boot, but Redmi 6 Pro wouldn't boot with locked bootloader, and it would show "This MIUI version can't be installed on this device".

The global phones I used (POCO M3 and Redmi 9T) do not have this problem, I have installed Taiwan ROM (TWXM) on both phones that came with the global ROM (MIXM) pre-installed, with re-locked bootloader, after more than 6 months, the phones still work well without software problems, they just feel the same as the phones that are from Taiwan.

Oh okay. So if I am able to switch from one EEA version to another EEA version without a mobile operator in order to have the updates in advance, I can also switch if I want from an EEA to a rom Taiwan, for example, or from EEA to an MI (global) ?

And another question, I had heard that as the phone was reset beforehand by unlocking the bootloader, then doing a flash clean and lock, some were blocked because for they asked for a Mi account, on restart, except that like the phone was reset (thanks to bootloader unlock), well the person was stuck because the phone no longer had the account registered. But I guess it's a minority, or it's a specific problem. Normally it doesn't ask to reconnect after doing "Clean all and lock" ?

Yes, you can install any other region of MIUI and lock bootloader as long as it's an official ROM for your device, not a custom ROM.

I chose to install the Taiwan version of MIUI because it has the MIUI dialer, while all other regions of MIUI except Taiwan and Indonesia only have the Google dialer which I don't like.


some were blocked because for they asked for a Mi account,
That is because MIUI's find device is enabled, if the phone had a different account signed in with find device enabled, after a factory reset, it will ask for the password of that account.

I think that usually happens when people buy used phones that the original owners did not remove their Mi accounts before selling.

I think if you are the only person who used the phone, it should be safe as long as you remember the password of your Mi account.

By unlocking bootloader, Mi unlock will erase the data on the phone, also when you flash the fastboot ROM, the data still needs to be wiped again.

So you will always need to type the password when the phone boots for the first time after data is wiped, if you have find device enabled, you will need to have an Internet connection to be able to type the password.

I am not sure what will happen if you disable find device before unlocking bootloader.

But when I tried to unlock bootloader of my phone without enabling find device, I had to wait for 15 days instead of 7 days.

Okay, so the only thing to do is to put the password of the Mi account with which I unlocked the bootloader (if asked at startup)? Anyway, I'm the sole owner, I bought it in June, it's just in case. Another thing, once I unlock the bootloader with Mi Unlock, and my data is erased, and therefore I end up with the phone's first setup screen, can I turn it off right away? I do not need to reconnect to my Mi account: I unlock the bootaloder, then I turn off immediately once it is well started and I flash in fastboot?

Yes, the password of your Mi account.

After unlocking bootloader, data will be erased and the phone will reboot, but you can just reboot the phone to bootloader (fastboot mode) by long pressing the power button and the volume down button, then flash the fastboot ROM in Mi Flash, and go through the setup after flashing the ROM, since data will be wiped again during flashing.

I received at the moment 12.5.1 (still under Orange operator rom) just before I unlock and flash, as if by chance. But I will still unlock the bootloader and flash, so I will have the latest version and then above all, I will have the updates faster.

    Would this work on Mi 11 Lite 5G as well?
    It should also work on your phone.


    If it doesn't boot after flashing with "Clean all & lock", am I out of options or is there a way to still put back the EU ROM that came on my phone?
    If your phone came with the EEA version (EUXM) installed, you should be able to install Taiwan ROM (TWXM) with the "clean all and lock" option.

    If you want to go back to the EEA version, you can just unlock the bootloader again, and flash the EEA fastboot ROM with the "clean all and lock" option.

    After unlocking, do I need to boot up the system and re-add my Mi account in developer/unlock status?
    No, even after re-locking bootloader, you can still unlock bootloader again with the same account without waiting, but there is a limit, you can only unlock bootloader 2 times in a month, if I remembered it correctly.


    So even if I brick it I can unlock again and flash EU back.
    Yes, if you do all the steps correctly, the phone shouldn't be bricked, but even if it doesn't boot, you can unlock bootloader and flash official MIUI again.

    I have never tried EDL flashing, but as I said, if you do it correctly, and your phone is not the domestic version for the China market, you should be able to re-lock bootloader and the phone will still work.
