Hi, I have bought the MP4 Player:
ATJ2091H
(Samsuns 643 - K9G8GD8U0M).
This player always goes in "USB 2.0 (HS) ADFU Device" mode.
I got no original dump of my firmware and I've tried to flash it with every 9.0.x firmware available without success: the screen is always blue.
What should I do for recovering the player? Could you explain the steps to me?
I use MP3 Player Utilities v4.07.
Thanks in advance
