Hello.
I have the mp3, no name, only that I found in the booklet is Audio Digital Player - 4 Gb, Battery 3,7 V 250MAh.
Problem is the following.
Originally mp3 was working normally. After a while he would not turn and run as mp3, but they involve a mp3 on your computer, the computer recognize it.
Assumed that the battery has run and changed the battery with battery 3,7 V 150MAh, but the problem remained only as a flash drive to use it, I decided it might be of firmware, I formated it , then do not think I put the correct firmware and now even the flash memory can not I use it. Computer does not detect at all to try to do another test.
When I opened it some of chip wrote
Ali DRA M5661P B1 0730 TG05
and the other manage to read only
Samsung
If anyone knows how to revive, please share.
Thanks !
