Hello, I need help,

I tried to install your ROM but it stoppet in the middle, here is the log:

20:06:13 042    **********Upgrade Done Success<0> Fail<1> Time<31964>ms**********

and now I am not able to run the tablet, there is dead android logo with red triangle on it, when I push volume+ power button I go to Android system recovery but nothing there is runing, when I push "wipe data/factory reset, it went through it and then nothing.

When I put apply update from external storage it asks for package to install

/mnt/external_sd

.../

but it is empty, I tried to make such folder on SD card, and also put it in the top of the SD card but nothing is working ...

when I update rkimage... it write E:failed to mount /mnt/external_sd (invalid argument)

please can you suggest something to me or I can throw away the tablet?

thank you ...
