Sons 2 in 1 tablet pc duel sim 6 weeks after warranty expired has had a software crash. I cant even say that its stuck boot looping as all I've got is backlight flicks on stays on for 20 seconds no logo no anything then flicks off for 5 seconds then repeats that same cycle over and over and over and..... you get the picture.. The only access i can gain is the to the boot menu, Power + Vol Down and that consists of 3 options, Recovery, Normal or Fast. All 3 options have been tried and the result across all 3 options results in nothing more then the above cycle. Need a steer Root Flash ROM etc ..
