Samsung s4 mini (gt-i9190) sim card not working after ROM install.

[Alirezab806]

Hello,
I have installed a new custom ROM (lineage OS 14.1) on my android phone plus a micro Gapps, now my device doesn't recognize sim cards, because the baseband version is i9192 instead of i9190.
i didn't find any firmware in for this problem, so I need help.
PS: my imei is fine I checked it and i'am new to this plus I am sure that I installed a lineage OS that is compatible, thank you!

The baseband (modem) is separate from the custom ROM it does not change when you flash a custom ROM (but will if flashing a stock ROM) , if you did NOT flash a separate modem file then your phone is probably what it says in the baseband. You need to check what the sticker says under the battery (if you suspect someone has changed the main board you can remove inner plastic cover to see model number on main PCB board)

If wrong you need to check which phone model of TWRP you installed. Now you need to check which ROM you installed. Download correct ones if they are wrong.

(Make a back up of imei & efs. Use this app
In case TWRP doesn't work properly https://play.google.com/store/apps/details?id=ma.wanam.efs
Now also back these up with TWRP if you don't already have a backup of efs /imei)

Revert back

I went back to stock ROM and everything works fine, I reinstalled different ROMs but neither work. Thank you!
