ERROR!! Install attestation key fail, SPMETA_DLL::META_FAILED

aocab

If anyone can shed any light on this error message please let me know.
I'm getting this error message when trying to recover fingerprint functionality.

I'm just not finding anything helpful that I understand.

Thank you

Flashing stock ROM with SPFlash works.
Restoring lost IMEIs with SNWriter works.

Trying to recover a dead fingerprint scanner (after a FormatAll+Download in SPFLash) with SNWriter fails.

I'm not finding much of anything helpful when searching for various entries in the log files.

Could someone in the know take a look at the log files for me and let me know if they see anything obvious that might me the cause of my issue?
