Hi
My tablet micromax P300 is corrupted and I need firmware image file for my tablet, please tell me where I can download it ?

Giving a quick search on internet, found this :

https://mega.co.nz/#F!cF0TECxI!dX-V0mtG1-Z9iXajdBV7Qg , download allwinner 4.1.1 version, that will work great with your tablet.

Thanks, that one worked great and I think its better than stock ROM.
