Circle problem (no recovery boot, dev is unauthorised for PC)

AL10 was flashed to kangvip b170 L29 eu. All fine few month but emergency calls for my region (UA) not work properly (call to police and listen fire dept answer). I think that problem was in location and try to flash from TWRP ru location file. But after this i see next problems:
- changes ROM ver from b170 to b152 (NXT-C900B152) //only locale file was flashed//
- cant boot now to TWRP (was 3.0.2)
- during boot red letters warning "your device has failed verification and may not work properly"
- when i try to run italian knife (sometime earlier i fix this problem with it) - it looong booting (yellow letters WAIT), and as i detect problem: "device is unauthorised" (see after run a cmd <<adb devices>>). So problem is dual :
1) on phone - i see red letters during booting "your device has failed verification and may not work properly"
2) on PC - device is unauthorised (earlier all was fine), i try to reinstall adb, nothing changed. I try to delete adb keys with their folders, on/off USB debugging switch...
Phone is unlocked and rooted, bootloader shows "phone unlocked".
Trying flash firmware using sdcard upgrade, flash stock recovery but device is rebooting and stops - because probably link path to recovery is broken. Few tools i try stops on <<waiting device>> because dev is unauthorised and i cant receive authorisation by on/off USB debugging
How fix this problems ?
