Hi, and welcome to our forums!
Yes, you could flash the firmware to one for the 52x model, but I doubt that a firmware flash will fix any problems. Sometimes it might solve a problem of this nature, but oftentimes it will not.
1/ You said that this is a refurb? Maybe the drive was dead to begin with.
2/ Could you be more specific as to what you mean by "not working"? Could you describe the symptoms and any error messages that you got?
3/ Check the usual suspects first. If the drive is old (used a lot by a previous owner before the computer was returned for refurbishing where the people doing the refurbishing may have not bothered with checking the drive), maybe it has a buildup of dust on its lens. Check to make sure that all the wires and connectors are secured. Etc.
4/ If you do decide to go the route of firmware, there are two things that you should do:
- First, make a back up of your drive's original firmware. There are not many 4832K firmwares floating around out there, so unless you have a backup copy, it'll be hard for you to revert back if you decide that you want to (and if your current firmware is anything but OPK3, we won't mind getting a copy of it in our inbox, either ).
- Second, you will need to use FlashFix on the 52x flasher in order to get it to flash your drive. See the tools collection sticky.
