i uploded the frimware the buttons don t work how do i delete the frimeware ?

Search for another *.rfw-file and try to upload it again with the ConsumerUpdate (=Refresh Firmware 3.1.20). The wrong firmware will be overwritten - thats's all ...

no don t work i tryd the new frimware is so stupid i cant uplod how to i delete the frimware?

Theire isn't any chance to get the old firmware back by deleting the wrong firmware. You have to search for another firmware and upload it to your player until you've found the well working firmware.

ok . but i just want to delete the frimware i want the screen white then i will uplod the frimware , the curent frimware is broke no uploding and when i try to open the mp4 and conect the mp4 the broke frimware will not work

You're caught in a Mission Impossible: deleting the firmware is only possible by uploading another firmware!

If this upload didn't work anymore, like you said, its time to think about buying a new player ...
