All right, finally I found a compatible rom for my android tablet “Dicra Tab 307”: it was almost impossible to find the original rom, none has it!

So, I found this:

and it works perfectly!

It is a fast rom, better than the original one.

Istructions:

 

-prepare an sd-card with the tool “Phoenixcard”

-burn  the .img firmware file on the sd-card

-turn off the tablet, insert the sd-card and turn on the tablet.

-a progress bar appears on it

-wait for finish

-turn on again the tablet

that’s it!
