PocketBook 623 Touch Lux - frozen

[pilak]

I have PocketBook 623 Touch Lux and it is frozen... I can turn it on and see menu, but i can do nothing. List of latest actions is empty, LED is on through all the time - i suppose that some process is working in background. I can connect device to PC, choose between synchronize data and battery loading, and see all files on SD card and internal storage ( i removed all books and audio files ). I downloaded firmware 4.4, copied into internal storage and successfully (manually) updated (i don't know what version there was before update) - but after that reader is still frozen after turning on. What else can I do, except sending back to guarantee repair? I bought reader yesterday as a christmas gift, everything worked nice. He froze after second or third PC connect, when i was saving books through Calibri.

Ok, I resolved my problem
I had to browse system catalog (hidden by default) and delete some state, temp and cache files. I don't know which delete was important but i deleted, among other things:
- wall.cache
- journal.log
- temp files with names of deleted books

Thread can be closed.


EDIT:
OK, got it second time. I had to delete only 1 file:
- system\config\widgets\config\wall.cache
Problem was some damaged epub file I think.
