Mine stock firmware version was HL03 and I wanted to do upgrade to HL09 patched so I readed many posts and did EEPROM backup. After successful firmware upgrade I tryed to run SMARTBURN application but it couldnt recognize mine drive. So I did downgrade to HL03 stocked, did EEPROM restore and SMARTBURN still refused to recognize mine drive. So I tryed to crossflash mine drive to Benq DW1810 <- to use qSuite instead but EEPROM Utility after claiming that upgrade was successful actualy didnt do notting at all and I was unable to flash drive with Benq firmware.
So I concluded that in mine case EEPROM Utility doeasnt write anything to the drive including restore EEPROM - no matter it says it does.
I used latest software version 3.7.2, and I did computer restart after every single operation I did.
Any known bugs in this issue or any suggestions? Thanks.
