If You've made a Security backup manually (via "Read Security") before processing the phone - write that backup back into the phone, with help of "Write Security" button.
Otherwise - write Security backup, which was created during first "Unlock" operation.

Please do the next:
1. Perform "Read Security" operation and upload received Security backup to any file-sharing service.
2. Upload first Security backup to any file-sharing service.
3. Upload *.log and *.logx of "Unlock" operation.

Post here download link for these files, we will check what causes the problem.
