Question how to fix unknown baseband in xiaomi 12 CUPID - Xiaomi 12

Hello , my xiaomi 12 has just lost imei and unknown baseband , does anyone know how to fix it ? Previously I have tried flashing to the enginering rom and doing the fastboot erase modemst1 command but it hasn't worked either, please help

If the bootloader is unlocked, use Miflash with the same rom that was on the phone when it was purchased.

Did you use Miflash and then no base band?
Which model is the phone Global or CN?

warranty is void because the phone has rooted

So it didn't happen by chance.
the only important point is that there is a Xiaomi rom on it., try with this tool if you manage to find the file.

Never tried. I don't think it's possible with the Bootloader locked.

Yes, This will wipe data.
You would receive this firmware by OTA already.
I shared the files mainly to get System dumps and other support to port apps.

You'll probably end up with a soft brick if you flash this on anything other than a C185 LIO-L29

Alternate region files won't cause a brick. Alternate models will cause a brick.
C185 Files can be flashed on C432/C636 etc. The device region will always remain untouched.

Hi Bro, try, only android 9 to android 8 you need other procedure.
It works... If bootloader is unlocked.
I have done it countless times, to check what is causing the volte problem.
Yes you can do it with stock recovery, because it doesn't matter!
You have to download fastboot rom, (download 10.3.3.0 or 10.3.5.0 if you want dual 4g option) (do not download recovery rom)
Extract the .tgz fastboot rom file and place it in your desktop folder (if you place it in any other folder, it may cause location not found error.)
enable usb debugging in settings and enter fastboot mode in redmi y2/s2 and connect to pc.
Launch mi flash in your PC, click select and select extracted rom folder, then click refresh.
 @THE bottom right corner, Change option to "clean all"
Then click on flash, reboot when complete.
If volte doesn't work, flash baseband firmware via fastboot!
Gud luck

You might have to downgrade to the version you were using before. Older phones just don't run well with newer Android updates

You are probably going to need to unlock your boot loader and root your phone, then use Odin to flash your stock firmware..

ODIN? Are you joking? This is a Xiaomi Phone, which has antirollback protection and no download mode (neither EDL)!
