After a couple of years of ownership of an off-brand player with a critical flaw (down button functions like a second up button), I found this site and decided to try some firmware updates. Now I have a truly dead player (not recognized by windows any longer and screen only flickers black on power up) I ask for help.
Before the attempted upgrade I learned this much from settings:
ctw500_s75
9.0.43
website where item was purchased:
http://www.geeks.com/details.asp?invtid=SV-1620-2GB
manufacturer website:
http://www.seal-usa.net/Eng/products/mp4/1620/1620.htm
I am using amv convert tool 4.0 for the firmware updates. The last update I performed using a file I more or less guessed at compatibility (I opened the player and the board has no ID number on it, the chip says CTW500 with a N or Z written across the chip in grease pen).
I'm hoping one of you guru's will bail me out. I'm planning to try tadad1's reset technique for the next firmware attempt, but I need help identifying the correct firmware.
