Redmi note 9 (Merlin): How to Downgrade from Android 12 ( MIUI 13.0.1) to android 10 - Redmi Note 9 Guides, News, & Discussion

Please how do I flash/downgrade my Redmi note 9(3/64gb) Merlin to android 10 (maybe to MIUI 12.0.4 or 12.0.6). I'm already on Android 12 MIUI 13.0.1.
My phone hangs alot, apps force closes after minimizing. Please help me out. What do I do and how do I go about it?

Did you try to allow apps to keeps open on developer settings?
If you really want to downgrade, so:
First, backup data.
Then, just flash MIUI version you want.
If the device got bootloop, just format data.

Please what's the procedure to flash MIUI, I have not flashed any Redmi device before. I'm new to flashing of phones or if you can refer me to a thread

First, backup data.
Then, unlock bootloader, enter in fastboot and flash any MIUI version you want.

Ok thanks. Which of the tools should I use in flashing, Sp flash tool?

Did you try to do a factory reset? Most of the time, when you change the version of MIUI, if it is not done, it slows down and gives errors as it happens to you.

Yes i have done factory reset but still experiencing it...
I just don't know which tool i will use to flash it

I flashed custom recovery on my note 9 Merlin and downgraded to 11.0.4 (A10) from 13.0.1 (a12), now I'm getting OTA update of 12.0.8, can I install the update with custom recovery and unlocked bootloader?
Note: I want to install another version of MIUI on Android 10 because my proximity sensor started having issues after the downgrade.

Just flash ROM and gapps and don't flash firmware while flashing custom ROM
While flashing stock MIUI ROM use fastboot ROM to flash and there won't be any chances of brick. MiFlash software checks bootloader index before flashing a ROM so it is safer way

So Finally installed GCAM after unlocking the bootloader , installed Redwolf recovery & rooted with Magisk & its working good. Will i be able to upgrade to MIUI 10 with OTA or have to follow some other process?
Also, which ROM & kernel setup do you use.
Thanks in advance!

Install Global ROM, Revert Stock Recovery afterwards

Good Day all,
I was wondering, is it possible to revert to the stock recovery after installing the Global ROM on the mi mix 3 China Version?
Reason I am wondering is because when I/We receive a OTA update from Xiaomi while using the Global ROM, will the phone be able to update or will it just freak out on me/us and die?
Currently I am waiting for my Bootloader to be unlocked (ETA 70HRS), I have all files necessary files downloaded (TWRP, Global ROM, Magisk v17.1)
Help/Advice would be appreciated :good:
Kind Regards

I find you very helpful in the forum and I would like to ask you few questions, I am thinking about buying the device but only chinese version is available here and I cant wait for the global to arrive
my questions are:
1- global version only released with 6GB RAM , if I got chinese version with 8GB , will it be able to run the global ROM ?
2- I have never flashed a ROM before , but I have strong knowledge in linux and command lines, will this be a hard task for me to do ? is it risky to brick the device ?
3- After flashing the Global ROM , will I receive official OTA updates directly from xaiomi without any problems ?

1. Yes no problem, I'm on 8GB model and worked fine
2. Really hard to hard brick, soft brick possible but easily fixable via fastboot to flash new system, boot etc
3. I believe so, not tested as there isn't a 2nd global update out?

After ! have put the Global ROM on the phone, i want to:

1. Yes

3. Only relock the bootloader on the ROM base it came with. So if your phone came with the Chinese ROM do not relock bootloader with global. If you do it's goodbye phone
Stock ROM will install stock recovery once phone has booted up

You'd have to use the Xiaomi EU rom with or without magisk as the global ROM has a CTS mismatch so won't pass safety net.

No, flashing the ROM will keep TWRP installed as it's a custom miui ROM.
OTA works and will automatically flash the update via TWRP for you.

Just a quick update for you all that I have successfully, unlocked the Bootloader and installed the ROM.
Just a quick note to mention that after you do:
fastboot flash recovery TWRP_perseus.img
DO NOT put in the command:
fastboot boot TWRP_perseus.img
After flashing TWRP just take your phone (either connected or disconnected from PC) and hold vol up and power. It will reboot in TWRP.
I tried rebooting into the recovery using the above command line and it just rebooted into MIUI Recovery.
Hope this helps :good:

Hello everybody,

It doesn't allow me to downgrade.
Can you help me please?

To come back to miui from AOSP you must use miflash tool to flash an official fastboot version of miui. It's necessary because miflash restores some partitions that are altered by flashing AOSP roms. Just remember not to relock the bootloader because miflash can do that.

You must bind your mi flash to your account to be able to use it to flash a rom on your phone. Note that mi flash will recognize your phone even if you had flashed a different rom on it.

Saw some bullying against you but glad this came out well. I will be testing soon. Just wanted to understand if we need to reflash stock before moving to this from Arrow. How about OTA implementation, is it implemented or will be implemented?

first download the fastboot rom for your phone from this link
Xiaomi Firmware Updater
The ultimate script that provides firmware packages for Xiaomi devices.
xiaomifirmwareupdater.com
and then extract the rom file .
download miflash from this link
Xiaomi Flash Tool - Official Mi Flash Tool
Download the latest and Official Xiaomi Flash Tool from the Official Xiaomi Flash Tool Website.
xiaomiflashtool.com
open miflash and click on select then choose the extracted stock fastboot rom folder. this folder will contains images. then connect the phone in fastboot mode. at the bottom right of mi flash app choose " clean all". be careful NOT to click on " clean all and lock" in mi flash tool, and then click refresh your phone should be displayed. check screenshot. then click flash. it will flash stock rom. at the end there will be a error dont worry about it. it is giving error because we are not locking bootloader. now you are in stock rom. let it boot into rom. after that just follow the instrutions mentioned in OP . this is the method i follow and it works fine for me.
anyone flashed the new build? i just flashed it and i am stuck in setup wizard. its not responding.

i tried restarting and i didnt use twrp or magisk. its a clean flash.
Flashed this rom and been using it for an hour only. So far not good. Setup wizard took solid 5 mins to open up. After setting up the phone and installing the necessary apps I found out that the apps are not opening . Either they crash or take 3 to 5 min to open up. Am I missing something? What about others? Pls do share your experiences. Anyway I believe the dev is very capable and will release a better build later on. Has lot of customisations though.
it does not matter its initial build
