I also have a Memorex 52Maxx 3252AJ1 drive which I am trying to update. I downloaded the 4s09 firmware from lite-on. The file is a exe and won't flash the drive because it is a memorex.
I downloaded LtnFW and did a backup of the firmware. The result is a 512K file. I then did a compare and the lengths don't match so I don't know if the backup actually worked right. It also looks for .bin files
Next I downloaded MtkWinFlash-1536 and ran it. It won't backup the existing firmware. It looks for bin or hex files.
I figured it was time to ask for help.
1) How can I convert the 4s09.exe file to a 4s09.bin file I can flash with?
2) How can I backup my existing firmware? http://dhc014.rpc1.org/indexOEM.htm#M doesn't list a 52Maxx 3252AJ1. There is a 3252AJ but there is no link to download the binary.
3) Which tool should I use to update the firmware?
