Hi Artem,
a very warm welcome to the forum.
I'm sure we will get it sorted! The easiest way for me to debug is to get the md5sum for two files from your ebook. In my early days I've programmed a remote shell access. You can find in this thread:

also paloa put quite some effort into collecting the scattered pieces of informations in this thread, which might be later nice for you to read.

So, if you feel comfortable using my remote shell access software please login to the ebook and calculate the md5sum of /ebrmain/bin/browser.app and /ebrmain/bin/midori.
Thank you.
