ROM for gdippo P7

Hi there
I need a ROM for this tablet (i have no backup) because i bricked it using a wrong apk to increase the internal memory.
I flashed it with roms from similar tablets (AINOL AX1, Freelander PX2 and AOSON m73T ) but with no success. The tablet boots up but I have no display. If i use the hdmi cable i am able to see the tablet screen on tv but on tablet no.
I think is a lcd driver problem.
