Hello ,

i have the model of the title and the installed version of android is 4.1.1 . I bought in the past other 2 same models but these had installed 4.1.2 that is more stable.

At the site of i-onik has 3 downloads for this model on section previous models. i download all of them but nothing update my version of android. The big one i do not know what is it and how i can install it, or something else. Any help will be great.

Thanks
