help with RBM2

[Guest]

Hi!

I have a big problem with my rbm2!

when I try to boot it stucks at splash screen, and when I boot from fastboot into recovery mode it says "E: can't find cache" and "E: can't mount cache"

It doesnt let me flash new roms onto it, cause after package verification, when it starts to copy new files it gets aborted.

what can I do now?

thanks
