FlashPro License Corruption After Firmware Update
Posted: Mon Jun 01, 2026 9:50 am
Hi,
FP SN: 21152
Connected VIN: SHHFN2***5017
The customer has already contacted you multiple times through the feedback system regarding this issue but has not received a resolution yet.
The FlashPro was functioning normally before the firmware update. After updating, the device now reports:
FlashPro Vendor: Unknown
Dealer FlashPro: Yes
Corrupted VIN data in the license section
Serial number displayed with a "?-" prefix
At the same time:
EEPROM Memory Test: OK
Flash Memory Test: OK
Firmware Checksum: OK
ECU communication is working correctly
This strongly suggests that the firmware update corrupted the internal license information while the hardware itself remains functional.
So the big question is how to proceed to fix this type of issue? I have no idea.
- Could you please review this case and advise on a recovery procedure or RMA process?
- Replacing the device would be difficult to justify when the issue appeared immediately after an official firmware update.
Additionally, can you clarify why new user registrations on the Hondata forum will not be activated?
=> Shady0286 = New User which reported the issue...
The car need further tune updates from me - I hope this issue will be fixed soon.

Thanks for help.
