I hope you can help, I updated my liton ihas624 b media code with media code edit but when written to the drive caused it to stop working. I managed to restore with a backup of the firmware and its working again, but can't seem to update the media code.
I did the following
1: open with mediacodeedit ATAPI.iHAS624_B.GL27.stock
2: updated/replaced dvd+9 media code with new code
3: save updated file
4: write to firmware speedpatched.stock to drive
5: drive locks
6: write backupfirmware using flash to restore
