Great, I'm going to cross-flash my 324 to 524 to enable labelTag.
Is there anything I should take into consideration when cross-flashing or is it straight forward like below instructions?
Update drive firmware, backup Firmware and EPROM, Select 524 instead of 324 when flashing C4eva's Max burn firmware.
I'm pretty sure that's not how you do it.
Try the following at your own risk - I'm only saying this because I don't want to be blamed if you brick your drive! This is the method I used and it worked fine. Make sure that if you have multiple burners in your PC that you select the correct drive in the drop-down list of any of the applications you use for converting/flashing, or you could end up flashing the wrong drive and bricking it.
1. Back up firmware and EEPROM.
2. Download the descrambled firmware for the drive you want to convert to from the codeguy's site (http://codeguys.rpc1.org/firmwares.html), so in your case you want the AL27 stock firmware for the 524. They don't have AL2A (the latest for that drive), but that's not an issue as you can update once the drive is converted.
3. Update the firmware using the file you just download, then fire up EEPROM Utility, click on the CrossFlash tab and hit the "Convert Drive" button.
4. Shut down your PC to power cycle the drive, then when you turn it back on it should detect the "new" drive and it'll show as a 524 in Device Manager.
5. Update the drive's firmware to AL2A (the latest for that drive) either using the exe file that comes with Burner Max, the exe file from Firmware HQ or Lite-On's SmartPack utility.
6. Back up firmware and EEPROM again.
7. Flash with the Burner Max firmware for the 524.
