Dead ipod clon [QS27C21]

[Funt]

Can anyone help me?
During testing my player with H2testw after writing of 2Gb data message that player is disconnected appeared. After that PC can't recognize it. Moreover, after few attempts I can't power on the player.
I just see greeting screen after that player going to power off. After few times I can only see clock and it going power off, then again power on and it constantly restarting
