Bootloop with broken recovery S7 G930F plz help !!

[issam30]

Hello , when I tried to unlock s7 on oreo 8.0 UK , on z3x It cant and It says try to downgrade modem , after rebooting the phone it was without baseband and IMEI , so when I tried to repair all that I Occurred in a deep hole
My phone recently got stuck in a recovery bootloop where it instantly boots to recovery mode. I tried getting into recovery mode via power + volume up + home command, but the recovery mode is not accessible (options to factory reset, clear cache, etc are not available), but instead says E: Unable to mount cache (Invalid argument) and proceeds to reboot after 30-40 seconds . I can however still properly boot into download mode.

After two days of working till now no solution I treid many roms and combinitions I am On u3 protection , any help

[issam30]

Also I flashed a TWRP in order to do hard reset , I did it but also dont work

install again the rom 8.0 the 4 files and the problem will be corrected but if you want to unlock it there is still no solution for u3

Your DRK is lost, Is FRP lock on in download mode? A solution would be to flash a No-DMVerity boot image. It will work fine then.

@ issam30

if your phone don't have any H/W issue for the Unknown Baseband, just apply this method your OG IMEI will be restored.

After completed the previews procedure, flash with 4 file official ROM, after flash if you get DM verification failed just write 6.0.1 CF auto root.

hopefully your phone will be OK.

I can see your post log, your phone CSC & CP is missing that's why your phone has Unknown Baseband problem.
