Flashing A Global Rom

[niktoo]

Hi all,

I have a redmi4 prime (bought from goldway HK), it came with Stable 8.0.5.0 (MBECNDG), bootloader is not unlocked.

If I understood everything, if I want to flash to a global stable ROM from Xiaomi over the actual ROM here are the steps (from miui.com flashing guide)

-get the global ROM from en.miui.com (it's a .zip file)
-put it on the phone via USB in a folder named ‘downloaded_rom’
-launch "updater", select ‘Choose update package’, and select the ROM previously copied

First, I'd like to know if my understanding is correct.

And Lastly, do I need to unlock the bootloader in order to flash a global ROM ?

Thanks for your answers.

you can flash global ROM directly via EDL mode from your current ROM. no need to unlock. thats what i did

i dont know about flashing via updater (like your explanation)

Thanks for your answer.
If I want to flash via EDL, I should use another package format for the rom ?
If I remember the ROM should be in a tgz archive format and not zip

Do you know where i can find these ?

you can download fastboot ROM it here: http://en.miui.com/thread-534756-1-1.html
it should be .tgz file format. if not, rename it
