Downgrading MIUI version

I need someone to check my understanding of the Fastboot process and some of the utilities.
Is MiFlash a complete overwrite of the device firmware?
Is a backup taken through QPST software download the NVRAM settings ONLY?
Can I downgrade from 9 to 8.5 using only MiFlash?
There appears to be an issue with 3G data connections dropping in MIUI 9, which is reported on a few other models as well. This is my wife's phone and she is not capable of dealing with most technical issues, so I want to stick with MIUI instead of LineageOS or something.

Yes you can downgrade from MIUI 9. Flash 8.5.9 fastboot using Miflash it is much better than other ways...

Missing WiFi MAC and IMEI - Mi 9

First off - Mods, I have the original box and sticker IMEIs if needed as proof.
I have been flashing between AOSP and Stock trying to fix a Microphone bug on my phone (see previous posts), when all of a sudden my phone will no longer connect to Network (IMEI unavailable error)
I went through every QCN backup + editing I could think of, even using my friends Mi 9 that we both bought from the same place in China as a QCN backup + my IMEI edits.
Everytime I edit the QCN and load it, the phone just boot loops immediately shutting down upon OS load. Using MiFlash back to stock didn't work, and I had to flash Evo X rom to get it to boot normally now, but I"m also missing WiFI MAC onto of my IMEIs.
I seriously have no idea what to do. I've tried every IMEI editing tool or Hex Editor in the book to put my original IMEIs back in to no avail. What am I doing wrong that cases it to restart loop when I push my updated QCN file?
Thanks in advance - Can provide whatever else you need.

As i understand you have China version of Mi 9, saying: "MiFlash back to stock didn't work" you meаn you have flashed official xiaomi china FASTBOOT ROM and it did't work?
Then i afraid the problem is deeper then in the ROM. Because by flashing stock fastboot ROM you flash everything that possible to flash, ROM and all images, with all setting like it was from the store.

Correct. Reflashing China ROM in Fastboot does not fix the problem. It fixes the bootlooping but not the IMEI issue.

Redmi 8 lost imei when miflash rom Global???

my redmi 8 running global rom then i have UNLOCK installed TWRP to load EU rom .. Today i mmlash on global rom everything is fine .. But my Redmi 8 has lost my IMEI, i can't use SIM application ... Someone help me fix it .. I need help ... Thanks

If you have not backed up the IMEI partition, I think it's the EFS, there's not really much you can do other than send your phone back to Xiaomi and hope they'll restore it for you.
Always do a full backup of all partitions right after flashing TWRP.

If you mean you can't talk on 13.0.2.0, and you got the camellia (Redmi note 10 5g china/india) it's a glitch on Global MIUI 13 and camellia version. Probably an issue w/ google's permissions update, it's glitching with unintended models running Miui 13 + Google Services.
You have to wait until (if) Xiaomi updates the Camellia model to miui 13.
Oddly enough, GSIs seem to be exempt of this issue.

Any update on this issue ?
Thanks

I have the same issue.
smartphone that can't make calls from it.
flashed the global version via fastboot...no luck
flashed the Indonisian version via fastboot ....no luck
the last thing I will flash the chinese version.

Has either of you tried flashing back to a past version - if so, did that resolve the issue?

Thanks, I just flashed indian rom, and it runs without any problem in system. But a small problem occuring at startup is that the first seconds of boot audio is not played.It seems that boot audio is played from the middle. Am I the only one with this problem?

im getting terrible call quality since updating to miui 13 its completely useless any idea whats causing this?

Dont flash the Chinese rom if you have the camellian. Only the camellia.
On camellian, it will probably brick it. I have tried it, it went to recovery instead. I havent wiped data but you could try, but chances that wont boot normally.
If you have the camellia, its good to go.

I have the same problem with my redmi note 10 5 G, miui 13.0.2
how can i fix it i have tried everything.
please a solution, thanks

Thanks a lot,
I've already tried to downgrade, but it's not possible, I'll try again, hope it works.
I don't know if I use camellia or camellian, what a difference, I'm confused!!!

camellia or camellian?
I suggest trying Android 11, Android 12 has an unstable 5G network signal.
Redmi Note 10 5G GlobalStableFastbootV12.5.6.0.RKSMIXM11.05.0 GB2022-07-05Download
In fact, I have brushed the rom of several countries, but still brushed back to the original CN region Android 11 latest stable package as the base package, and then brushed into linegaeos GSI
The main thing is signal stability

"it's clear" reminded me of platform tools. Sorry if you actually dont know how to do the procedure, anyways, download adb here > https://developer.android.com/studio/releases/platform-tools
Boot your phone into fastboot mode, then, open the folder of platform-tools (should not be compressed or i winrar, extract all the files to a folder), in the search bar of the folder type in "cmd" and now type:
fastboot getvar product
then it should either appear camellia or camellian

Try searching up online and on youtube you will get alot of results.
If we could support TWRP we could flash Magisk GApps easily but Im not sure if any of the TWRP builds we got on the forum even work for flashing if a/b devices dont support recoveries.

Question IMEI issue

Hello,
I have rooted my device and installed the original android 12 from this forum and now i am getting IMEI 0 issue, i tried a bunch of stuff on the internet how to fix it, but i just can't restore it. Can anyone help me how can i change the IMEI ?
Thank you.

I'm not sure anyone is going to help you with that, as it is usually associated with criminal activity. I'm not suggesting that's your intent, but I wouldn't expect any assistance beyond 'google'.

You bought a used device, correct? Android 12 wasn't the original OS for the S21 Ultra, it was Android 11. Was the IMEI 0 issue there before you rooted the device? Since you've rooted it's highly unlikely you can revert to Android 11 plus XDA isn't the appropriate forum for manipulating your IMEI.

You have 3 options:
1. Head to the nearest samsung service center and tell them you want to fix the internet issue and don't mention root (act dumb) if they said its out warranty say y'll fix it on your bill but as long it's software fix.
2. Replace the motherboard at any professional repairer with a used one that has a valid IMEI and baseband.
3. If neither method works... Get rid of the phone and buy a new one, cause it's just a "6.8 inch calculator" and it'll take a lot of your time and effort unresolved.
edit:
4. Maybe there is a way to write the IMEI & Baseband back on the protected partitions using root permissions or ADB, try termux with the root but i dont know for sure.

Thank you for your answers.
I will do as you said. Because i updated to the latest version, i can't re-roll Android 11 and this issue is not fixable at the moment on android 12.
