iLiad issues with MMC and SD card

[maxmin]

Hello!

I auctionned an Iliad v2 on ebay and I've got some issues.
1.) The iLiad doesn't read the CF-card properly. I can see (sometimes) the folders but can't open any files.
2.) I have to reset the iLiad regularly because it doesn't stop. It crashes almost always when I put the CF/MMC-card with new files before booting.
I already flashed it but it didn't seem to serve anything. I can't really locate if it's a hardware or a software problem.

I can use the iLiad, but only with the 128MB MMC card and I have to put the MMC card always out before I boot it and put it in after. It works but it's annoying. :/
Probably I'll need to buy a MMC/SD-card.

Is it worth to try to format the iLiad? Is it still possible to get updates afterwards (still now)?
