So far as I know, you can't downgrade the Binaries. But still u can manage to find someway to leave A11 and back to whatever A u want since customs ROMs ( based on stock ) are seems enough

Hi, thanks for answering. I found an A9 rom for my phone, but when i flash it in TWRP 3.6.1 A11 it gets stuck in bootloop. Tried flashing multidisabler afterwards and wiping it but still nothing. Any ideas?

Flashing Custom Recovery and/or ROOT on A50 is quite different with few extra steps. Do the searching in our forum, u'll find the information u need.
P/S : Always read carefully ROM's Install Instructions, it cover all the info u may need!

For custom roms, not official (Oxygen), you need custom recovery eng-stk, first.

No, flashing a kernal won't result in a different twrp. BUT inside the kernal downloads he also has a few Twrp releases. You will need this one https://forum.xda-developers.com/devdb/project/dl/?id=22806

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!

Yes you can upgrade to MIUI10.. but you have to flash full recovery ROM, still you will get OTA update from xiaomi but its always recommended to flash complete recovery ROM

Downgrade MIUI 12

Hi guys, did anybody try to back MIUI 11 from a safe method ? Via fastboot or recovery?

No, no one was ever THAT stupid. Why on earth would you roll back that amount of security fixes and upgrades? Is it because your spirit guide told you so or are you just not right in the head?

You can say whatever you want fellow.. but in my perspective, the phone just came worst about battery and performance, im getting lag that in MIUI 11 was not present. You are so polite, have a nice day

Sorry for bothering with more questions. I've not flashed a rom since many years before.
First i need to unlock the bootloader, then use Miflash with the flash and erase data option (without locking bootloader), am i right?
Is there an specific tutorial? Or any recommended Miflash versión for MIUI12? Further, do i need to root device?
Thanks for your attention. Regards

you should unlock the bootloader if using twrp, Miflash mostly will erase your data (without locking bootloader), u r right
mi flash would be easy for u. but only official MIUI12 ones you can flash.not need root to flash。

i didn't try them all (maybe 6 builds if i remember correctly)
they all sux compared to aosp (they use more resource "cpu" & "ram") so inreturn they use more battery life ...
I rolled back to MIUI 11 as 12 was poor.. Battery life being biggest issue.. Yea I go back to August security but I don't care.. Please go ahead and hack me lol.. We may get MIUI 12.5 in the future so I may try that if Xiaomi can be bothered to check it before release.. I'm happy staying on MIUI 11..

Im not satisfied even with xiaomi.eu thus im going to give a try to RRos as you recommend. But, despite im in xiaomi.eu 11.0.6 which are the steps to get a good flash?
First do i need to wipe phone then flash MIUI 12.0.3.zip, right? After all i flash the RR.zip
Have you tried RROS-Q-8.6.7-20210308-ginkgo-Milestone ? Comes with sixteen kernel?

Copy all your important data (on internal storage) to a pc or external storage
if you are rooted make a backup of your apps+data (to restore after instaling rros)
reboot to recovery
wipe data/cache/dalvik/system/vendor
Flash RRos
Flash sixteen
Flash DFE
Format data : yes (not wipe) (this will erase internal storage)
reboot to recovery
reboot to system
I'm currently using RROS-Q-8.6.7-20210308 (it does not come with sixteen)

It is... Flash it via TWRP after wiping your device and profit. Think about that´s a factory image with own recovery, lost root etc... And sorry for my ignorance - but as a senior XDA member you should know how to flash original firmware...

Redmi note 9 (Merlin): How to Downgrade from Android 12 ( MIUI 13.0.1) to android 10

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.

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.

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.
