Dreambox keeps losing flash

Everytime i flash my mates dreambox when i restart it i get the no ca error found again?

It flashes ok everytime but its as if it losing the flash

come up bios no ca found

do you reckon it could be the L800?

Are you sure of the sim in the box ? As to me it seems that the sim is loosy. Which sim is on his box and which image do you flash (we need the exact filename and even where you downloaded it/Link) ?

And.. if it's a hardware issue.
Maybe if you measure the Nand flash chip I/O pins it could say something.
They should be in the x.xx Mohm range.
Also check the CE pin (Chip Enable), if it's connected to ground, if not, it disable the nand flash chip, but you are still be able to flash the chip.

Some info about the Nand flash chip see the picture on this topic.
