[QUOTE=memory;2657134][B]use at your own risk.[/B]
The second generation 1.03 firmware included in the above pack is invalid (the others are OK).
Use this dump instead: http://www.mediafire.com/file/efcl29ffbbg2sva/PX-LB950SA_2nd_generation_1.03_dump.rar
Be very careful when crossflashing a 1st or 2nd generation drive to a 2nd generation drive! This is more risky than usual.
If your burner is a 2nd generation one, or once your drive has been crossflashed to a 2nd generation firmware, then you will no longer be able to correctly dump its firmware using the current Firmware Utility (FU) or any other publicly available tool (the FU will appear to work OK, it will produce an output file of the correct size but unfortunately the content of the file is just random garbage if you look at it with a HEX Editor). The current available 3rd party tools (FU, EEPROM Utility, etc) are a bit old now and they do not work properly (or work only partially) with 2nd generation drives.
The problem is that once you flash the firmware (using the unlocked flasher method for example, which should ensure a correct flash) the Convert Drive function of the EEPROM Utility might not work properly. If it doesn’t work, you’ll be stuck with a blinking drive. Make sure you’ve got a valid dump of your current firmware (check with a HEX Editor to make sure) before attempting to crossflash, so you can return back your drive to its original state if the Convert Drive function fails to work.
Also to be on the safe side, make sure that you backup your original EEPROM before you attempt a crossflash (the EEPROM Utility can create valid backups even for 2nd generation drives) and keep it safe just in case.
