I have exact the same problem, did you solve your problem?
If you do please let us now how you did it??

@gutemine

Thank you for the reply!

I already have the latest second stage bootloader #84 flashed to the device.
The firmware is: experimental-dm500hd_20120502.nfi

So the problem stil exist.

Can Dream Multimedia repair my box do you think?

The box is not under waranty anymore!

I now this is an older post but did someone even nows what causes this problem?

Some technical information would be nice

But it's impossible to flash the newer ones.

He report that the flash is successfuly but you see it's an older image or loader thats inside!

So I guess it's not so simle after all or do you have any suggestions?

In my case I see this in my terminal:

*** 002 checking CRC... 
CRC check skipped. 
nand-set-pen 
oob: ff 
start flashing... 
00e08000 bad 
01ed0000 bad 
029d0000 bad 
finished.

Seems to me that the NAND FLASH chip is gone bad or having no stable power or have loosing legs from the PCB that might be also have a short circuit as resulting in not programmable chip.

Does someone have any idea's?
