CM70048 didnt work for me. I get an error when i that file. The MP3 utility rejects it saying the firmware protocol is not the same as previous firmware. I could into U Disk mode with 3 - 4 firmwares but nothing really seems to be working. I didnt get the hour glass or anything on the screen. Still workinf and downloading firmwares.
Thanks for following up.
I think by the time i finish with this mp3 player, i might start making my own brand
