C760 Problems, boot, service and reflash fail Options

[louigi600]

I just recieved today (from a user on this forum) a c760 that I was planning to use for developement/testing but I'm having a few problems:

The device did turn on (and was running cacko 1.22 or 1.23) but when I followed the procedure (ok+on) to flash xpdarom I noticed that the power led did not light when I inserted the wall charger.
I attempted anyway the procedure but it did not boot into the flash menu.
I then attempted a normal boot but that failed too.
Next I tried the service menu procedure (D+M)but that failed too.
So I then tried to see if I could get the power led to light with a sync/charge cable but still no luck.
I also tried with a fully charged battery from my c860 but still no luck.

Anyone have any ideas ?

Regards
David

I found somewhere on this forum a description that got my Z to go into service menu (all other descriptions failed on my device):
Take out the batery and leave it out,
Take at least a 5 second pause,
Press and keep holding D and M keys on keypoard,
Push in the power chord while pressing the keys,
Let the keys go and wait a few seconds the service menu should come up shortly,
Put the battery back in close cover and lock.

I then attempted to restor original nand flash backup that can be downloaded from
http://trisoft.de/en_slc760.htm

But after having nand flash restored the device it still fails to boot.

I restarted the service menu to do a flash cksum only to finf out that :
ROFLSYS is in state NG
PRESET is in state NG

Anyone have any ideas how to fix this ?

Hopefully that "ROFLsys" is a typo. Otherwise your machine might be making funny at you (G).
