[Upgrading, Modifying and Unlocking] p1ceus:
Hello all :)

I just bought Archos Arnova 10 G2 few days ago and till now I would say I kinda satisfied with the device. But since we are here on XDA, enjoyment from this device could be even better ;)

I tried to put a custom rom (here) to my device but unfortunatelly I'm not a lucky guy and device didn't boot at all. So I ask uncle Google for help and found this great tool that allowed me to root the tablet easily and put some extra apps into /system/app. I then encounter endless problems with Maket to even get it to work and found a way here (download the attached .zip, copy it to the device and install .apk's in order posted, reboot the device and you have Market and Google apps up and running ;)). And this is where my problems started to appear...

Market in that .zip is veeery old (v1.82) so I put there new version (3.3.11) and it seems to work well too but just until I try to install some app from Market => FC.

I read something about permisions set wrong or some another component/app is not installed or incompatible with Market 3+ (btw, only version working is 1.82 and 3.3.11 -with problems. Another version give my FC during loading).

So, now to the point :) I managed to get some feedback from LogCat when Market FC:

Can somebody advice me in which direction should I look to fix these errors?

Or another thing, /system is not RW on this device, so every change I do I have to flash whole ROM again :/

I tried these command in Terminal Emulator but without luck:

su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock4 /system

Thanks anyone for kick :)
