Is it normal that my baseband is "Unknown" ?
NO SIM
Hi thanks for this. Flashed but SIM card is no longer detected. Tried multiple wipe/flashes and no go. LOS16 was working prior. What have I done wrong? Thanks!
Exactly the same Problem
Only thing left to try is flashing back to newest stock via odin and doing everything from there again
I experienced the same problem. Simply reflashing Current Stock and going from there did not work for me.
It seems the data on /EFS got scrambled and the IMEI can no longer be properly read by Custom Roms, which results in no service - Current Stock didn't have issues with this though... (I switched quite a number of times between the two investigating this) Here is how I fixed it:
Backup EFS (As far as I read messing with EFS could go quite wrong...)
Mount & Delete EFS using a Custom Recovery.
Boot to Bootloader and re-flash Current Stock (This will restore EFS; Flashing BL might be enough - didn't test that, as I already spent hours trying to resolve the issue...)
From here on I was able to Flash TWRP/Repartition/OrangeFox/LOS17/GAPPS and cell service was working again.
