Hi guys.
I have been using stable ROM .EU V13.0.18.0.SLECNXM on my 12s PRO. After release, i flashed MIUI 14.0.22.12.5.DEV BETA version.
After short usage i discovered some issues, mostly with Banking apps not working because they see this as unsecure ROM.
I decided to flash V13.0.18.0.SLECNXM back.
On my surprise, after flashing stable MIUI 13, i discovered that my SIM card can not be discovered. Tried other SIM, no difference.
Than i tried to flash back again to MIUI 14.0.22.12.5.DEV. And SIM card worked again.
Can somebody tell, where is the problem? IS it solvable? Or should i wait for stable .EU MIUI 14 for my banking apps to start working again?

Thank You in advance.

After back to MIUI 13, do factory reset from your phone (not from TWRP). Hope this can use full

If you want to use banking app on MIUI 14 . Rename TWRP directory with different name or delete it.

Thanks for advice, but it did not help. After initiating factory reset, phone restarted in TWRP and showed error. Than i tried to flash original China ROM via Miflash tool. Again, no SIM card detected. Tried to Factory reset from there. After restart, reseting process just crushed after 2 %. Dunno if it did a thing or not. After restarting, no improvement. The SIM can not be detected in MIUI 13. Any other guess? Thank You.

Hello, everybody.
I found a beautiful Sam Beckman's youtube video which solved me safetynet issues for banking apps for Miui 14 Beta.
Thanks to everybody for help. Hopefully this also helps to others:

How to use banking apps on rooted devices
look here…

And check if safetynet is green/ok

Google Playstore "Play Protect certification" - Device not certified
  • clear Data "Google Play store", "Google Play services", "Google Service Framework"
  • reboot

I have had the same issue with my SIM on a 12s ultra. Flashed the A13, had to go back, then no SIM.
The way to get SIM back is to extract modem image from the v14 ROM and flash it in twrp to both a and b slots of the modem. Reboot and SIM is back. Hope it helps.

It is super easy . if you downgrade from Miui 14 to Miui13, the base will be lost to cause your SIM can't be read.
you can dial *#*#25327337#*#* , and the phone will restart automatically .
then you will find that your phone alived !!!
