After this operation phone lost its baseband and imei (shows Baseband unknown), writing first security backup (Security-SM-G935T-RF8H30789SM-06-12-2017_23-53-51-.asec file) doesn't solve problem. Reflashing stock 4-file fw also didn't help. Please Octoplus team, provide me how to revert phone to its initial state and after that unlock it.

Hello.

Writing Security backup should return the phone to it's initial state. Also after writing Security backup try to write Android 7.x firmware.

Please Octoplus team, check my backups and logs from the first post. I have a suggestion that software have read damaged first backup, and after writing it back to phone, baseband was lost.
I've already tried to flash 7.0 firmware, but with damaged baseband phone hangs on logo on 7.0 fw, it can boot to system only on 6.0.1 now. As you can see from logs, baseband was ok before operations. What shouls I do now?
