Firmware update program hang-up
My player was updated with wrong firmware.
After that it was detected like "USB DISK DRIVE", but I cant format it in any option of format tool and player wasnt work. Method like "Push all button" cant help. So firware update program says somthing like "Write protected".
I short pins on NAND and windows detect "USB 2.0 (HS) ADFU Device".
And now when I try to recover firmware update program hang-up below half of progress bar with task "Downloading the restorable main program".
At first I wait about 2 hours... after unplag device.
Thanks for the answers!!!
