Going back to Indian stock from Global - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I have an Indian Redmi K20 which was on 11.0.3 India rom. I unlocked the bootloader, rooted and installed the global 11.0.5 because I wanted to try a custom rom. Now I would like to go back to Indian rom but I'd like to keep the unlocked bootloader (assuming it doesn't mess with official ota updates).
I tried flashing the Indian 11.0.3 with miflashtool but got an anti rollback error, so I had to flash 11.0.5.
How do I go about it?

How to rollback to stock?

Hi there, im currently on the leaked oreo beta on my A2017G but since this month there should be the official oreo out i wish to rollback to stock. Do i just need to flash latest rom on it? Do i need to relock the bootloader and remove twrp to get new ota updates?

EEA 10.3.30 to 10.3.2.0 = anti rollback brick?

Hello.
Hope you can help because I'm kinda confused atm
My device is redmi note 7 lavender, came stock with EEA (european global) rom.
I recently unlocked the bootloader, installed twrp, tried a few roms (xiaomi.eu, crdroid, phh-treble gsi, etc). Currently using crdroid without issues.
Previous to all this I was using stock EEA 10.3.2.0 firmware and then sideloaded ota for 10.3.3.0.
According to this post this phone has ARB
What I'm wondering is if I were to go back to stock firmware, would I brick my device? Because the only available fastboot version for EEA is 10.3.2.0 which is older I guess, but I'm not sure exactly how ARB works and it that would trigger it.
Thanks in advance
I recommend that you do not return to the previous version, sometimes the ota bring changes in the bootloader, and you can leave it hardbrick as it happened with several Motorola, even with devices that have a Qualcom processor. Expect that someone else has done it or that the software is released to an equal version.
start to investigate the changes that were added
I leave this link you fence to interest move from the EEA to the global version

If you're asking specifically about turning back from 10.3.3 to 10.3.2, then there is no problem (I went from 10.3.3 to 10.3.2 to 10.3.3 again and everything is ok).

My RN7 is global, came with 10.2.3.0 as stock, I updated via OTA to 10.3.5.0, and I was wondering if I try rolling back to 10.2.7.0 (As I didn't find any rom of 10.2.3.0 for global PFGMIXM) it will trigger the ARB? thanks in advance (both have lvl 4 in adb query)

Sorry to bother but, did you bricked going from which-to-rom, using TWRP or the mi-flashtool?

Rolling back firmware only through twrp, trying to get previous drivers for international version which bug less on proximity sensor.
As the phone is unlocked I might have found a way to restore from brick without physically opening the phone. Will keep you updated.
Edit/Update: yipeee!!
Need to completely flash the phone based on the procedure detailed here. And reflash whatever custom ROM afterwards as you get back to stock.
Just rolled back from Global 10.3.5.0 to 10.2.7.0 with MI Flash Tool (fastboot rom type). 0 problems, seems you can rollback from your MIUI 10 ROMS of the same version(EEA with EEA, Global with Global, etc, and of course that these roms have same ARB 4), at least worked for me, posting this future records.
Actually firmware tool (as opposed to twrp) is the way I reset ARB.

Relock bootloader and back to Global ROM

I'm on weekly EU ROM (Xiaomi Mi 9T). I want back to stabile Global ROM and I want relock bootloader. How can I do that? Please give me step by step guide with downlaod links. I tryed with MiFlash tool but without success. Thanks in advanced
just for info, why would you go from .eu to global if global is noticeably worse(based on opnions ofcourse)?

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.

poco m3 clean & lock bootloader after region change from global rom

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).

Yes, the original firmware and not the mode one.
