Everything seems to be ok - the problem was in rmt-storage service.
I'll post working recovery in another thread.
P.S. Great to hear you've returned, Sebastian404. Thought you've suicided according to http://android.podtwo.com/ <- change that depressive s*** to something more optimistic=) could you please share your v9plus configs on github, so I could understand how have you fixed usb mount? for now I've used binary from your b2-recovery - please look here - https://github.com/s.../device-v9plus
Interesting, I believe that rmt_storage is something to do with communicating with the modem, I can only assume something in the kernel is looking for that... I dont have a device to play with..
what is your problem with the usb mount?
I'm recovering from a bout of encephalitis, I've been very ill for the last few weeks, but I'm getting better, hopefully be able to do more stuff soon
on, that's a quote from the Matrix Reloaded btw, I've never used the www domain for anything, and that quote has been there for 9 years now
