Does anyone know where I can find a new battery for this MP3 player (which is not available anymore, except at 100$ on Ebay (WTF!!!)) ?

Thanks a lot for your help

There are lots of audio recordings, and other audio files I would like to recover, but all the players are completely unresponsive. They won’t power on or do anything.

I have tried multiple times to connect them to my computer using several USB connectors (to ensure It isn’t the cable) but nothing happens. My computer won’t even register them being connected.

Using a multimeter, I tested the + and - solder points while one player was plugged in, and there is voltage flowing to the battery—not that that would make a difference one way or the other. The batteries will charge, but that’s about it.

I have watched multiple tutorials, trying everything possible, but so far nothing has worked, and the Mp3 players are still unresponsive.

At this point, I think the only thing that might work would be to desolder the 48-pin NAND flash memory chips (whatever they are called) from my Sandisk Clip Zips, and transfer each to a Sandisk USB drive with the same gig. I saw a few videos where someone was able to recover files from a cracked USB stick by desoldering the memory chip using a reworking station and transferring it to another identical USB drive. They were able to connect it to a computer that way.

I think you can buy 48-pin USB socket/adapters or buy parts from eBay and rig together a USB reader of sorts, but I’m not sure how to do that.

If you happen to know what would be the best way to recover the audio from these players, I would be very grateful.

Also, can all 48-pin chips work on different gig USB sticks? I mean, my Sandisk Clip Zips are 4gb, and my Agptek is 16 gb. Could I transfer the 16gb memory chip from my Agptek to a 4gb Sandisk USB drive so I could use the same USB drive for all (assuming that method works)? Or do the chips strictly work on boards meant for the same gig/manufacturer?

Any input would be appreciated.

Thanks.

Because of that I couldn't increase or decrease the volume, traverse through the menu item list etc.

Originally I connected through Rhapsody, but that doesn't work anymore.

Which means that I can't add or delete music or update.

Is there some other program that will enable the connection? Does anyone else have this problem? Is there anyone who can help?
