Okay...let's try an other fix....open the...Open the comercial product tool recomended on topic begining.

conect the ADFU device.....click in DONWLOAD....

after this process, the mpx is disconected and re-recognized how an flash disk....the rest is the same..... format and upgrade....

The problem occurs when the memory chip (the biggest one) is not pressed. So you have to put a piece of paper (or what you think is better) on it and put the back cover back on, so there is pressure on it. After that try to recover the player with the full firmware. I tried it with my player a few hours ago and now its revived!!! I hope that this fix helps who need!!! Thanks to the user "Jesper" who discovered the fix! Thanks to all!

im having problems like read/write device info failed but im running XP already,ive tried so many versions of upgarde tools even product tools but the erase flash is inactive.what should i do?
