Android. ERROR_COULD_NOT_MOUNT while mounting complex ciphered obb file

view story

http://stackoverflow.com – I develope Android app, which uses ciphered obb file. This obb file consists of 3 files (I created it with jobb tool). On the most devices all is ok, but on the three devices there is ERROR_COULD_NOT_MOUNT. And I don't understand how to fix it. I want to distribute app without any errors :) Please, help me to do it! :) That I have tryed: 1) Unmount and mount obb file; 2) Create obb file from the folder without "read-only" attribute. But all of it won't work. Steps to reproduce the problem (including sample code if appropriate). 1) Create folder, put into it 3 different files. 2) Create obb (HowTos)
