How to Unlock Bootloader, Unbrick and Install correctly MIUI 11 on MI9T (9.9.26 to 20.1.21)

[Poney70]

how can this be correct if OP said we had to install Xiaomi.eu 10.3.15 Stable and only after weekly beta (with no wipe or format in between)?

OP said to install stable .EU ROM first to potentially avoid "problems with the initial configuration and you could have a black screen with no solution on the Google Login so you can't continue configuring." But no issue with latests weekly/beta ROMs.

Oh ok, I thought it had something to do with needing a"stavke base rom" before needing to install (hence the weekly install without wiping).
I'm having major Android system battery drain, can't have more than 5h SoT in 1.5days with low usage so should I wipe system data and cache and reflash latest weekly to see if it solves it? Or should I do anithing else?

Wait next weekly update and wipe Dalvik/Cache if you want, but how and from which ROM did you install latest weekly?

Hello guys,

I have a Redmi 5 Plus with the lastest official Global ROM installed (MIUI V11.0.2.0).

However, yesterday, while i was playing a game, the phone has just stopped responding, i could still hear the sound but the picture was completely frozen, making the phone stop responding.

So, i have pressed the Power button for a few seconds until the phone restart. After that, my phone has been stuck in the boot logo, it doesn't load the system.

My main problem is that i have the bootloader locked and i have already searched and tried the following:

1) In FASTBOOT mode, i tried to flash the same ROM (Global) with MiFlash Tool - (NO SUCCESS: it keeps having the same error "ACK count don't match")
2) In FASTBOOT mode, i tried to flash the Chinese ROM with MiFlash Tool - (NO SUCCESS: it keeps having the same error "ACK count don't match")
3) In EDL Mode, tried flash both ROMs (Global and Chinese) with MiFlash Tool - (NO SUCCESS: it keeps having the same error "ACK count don't match")
4) In EDL Mode, tried flash several ROMs (Global, Chinese and also more older ROMs) using the MiFlash Tool BETA - With this tool i have succefully flashed several ROMs, however, the phone is still in the same situation, stuck in "Boot Logo"; So, NO SUCCESS;

At this point, i'm running out of ideas and i would appreciate if someone could help me.

Used "Format Data" in TWRP so? New 9.12.12 update is available, try it.

Didn't understand :/
After installing global rom, I formated in twrp and wiped system cache and Dalvik and then flashed weekly.

Hi
Thanks a lot for your OP : work great for me with the official twrp.
Glad to be back on xiaomi.eu roms

I've started using .EU yesterday for the first time and the difference from Global Stable is brutal. Android 10, bunch of new features, improved smoothness.. so much better! Thanks for all the hard work devs!

In case there's still someone wondering how to install latest weekly, that's how I did it:

Coming from latest Global Stable MIUI 11:

- flash LRteam 3.3.1-1109 TWRP
- reboot to recovery
- format data > type yes
- reboot to recovery
- copy ROM from PC to phone
- install latest weekly EU
- wipe dalvik/cache
- reboot system

LRteam 3.3.1-1109 TWRP is from the .eu post (https://androidfilehost.com/?fid=4349826312261630584) or is other?

3.3.1-1109 twrp is the latest for android 9 rom and move to android 10.
TWRP_davinci_10.img here is the new one official TWRP for android 10 rom.

It is automaticly installed when installing EU rom.
No risk.

from stable official you must format data and 1109 twrp. twrp-10 will be installed at reboot.
no bother.lol
EDIT
WAIT UNTIL TOMORROW THE NEW WEEKLY WILL OUT.
This week it is buggy at Netflix and some other details.
just follow the topic.

hmm
i thought that i just need to download the twrp-10, do a format data, reboot pass the .eu to internatl, reboot install by twrp and its done
i need to do a format data with twrp 1109 first of all (this one is from your post, right -TWRP-3.3.1-1109-REDMI_K20-CN-wzsx150.img )?

EDIT: thanks for helping...used the TWRP-3.3.1-1109-REDMI_K20-CN-wzsx150.img to move from global 11.0.1 stable directly to the eu 9.12.19
and works all great, already updated to the last one 9.12.26
much better than the global one (the global my battery was draining a lot...was only 3 to 4 h SOT in one charge...now i have 4h and 55% remaining...

The updates of this year seems to have worst battery...if I had done a backup I would go back to the last one of the last year...

Hello,
I have try to install this rom but i failed...
I was on 11.0.3.0 (PFJEUXM), it's android 9.
I had install TWRP (greek version) then directly 20.1.9
But i stuck on loading (mi screen with dots) wait more than 30 min, no way.

I try to install other custom rom (pixel for example), same stuck.

I tried to flash back with miflash, but i had rollback error.

To bypass it, i have edited the flash_all.bat file and i successfully flash the flashboot rom (10.3012 EU).

NOw i have antirollback set to 1.

How can i flash this rom?
Any one can give me a guide?

Thanks a lot!

If you don't "Format Data", that's why it can't work...
And use Official TWRP instead.

Bonjour
Pour débloquer le bootloader il y a pléthore de tutos, ici ou chez Google search.
Ensuite il suffit de flasher le TWRP officiel dispo en téléchargement sur la page de la rom stable:

STABLE RELEASE RULES WHEN POSTING 1. If a ROM is not published DONT ASK ABOUT ITS ETA 2. If a ROM is not published DONT ASK why! 3. If a ROM is available, download it and use it 4. If a ROM has bugs, post the bug to the bug section if the BUG is not already listed 5. If you use any form of...

xiaomi.eu

Tout y est expliqué très simplement et pour le mieux.
-------------------------------------------------------------------
Written English is mandatory:

So:
Hello
To unlock the bootloader there are a plethora of tutorials, here or at Google search.
Then just flash the official TWRP available for download on the stable rom page:

Yesterday I was trying if is possible to install directly the last beta version 20.1.21 without stable version, just making a format data and flashing, and the result was good, to install last version just make a format data, download 20.1.21 and flash it. It works for me.
Download it on your computer, make a format data and reboot the phone on TWRP other time, connect the phone to the computer and transfer the rom to your phone, and flash it. Wait 10-15 min and the phone is going to start without any problem.
NFC works and GPay works too.

Hello, I'm technically new to this for this phone, it wasn't exactly a problem for past phones. Since you just stated that this update is a bit outdated, I want to know what I need to do to get the xiaomi.eu ROM successfully after I unlock my bootloader for my mi 9t. Thanks.

I just updated it to install the last beta version directly just with 4 easy steps.
