It appeared the happy owner of this device S820. Pulled me it flash... moreover not to make backup, now I can not find a suitable firmware. The problem, probably, in drivers of the screen, bodies is stitched, but the image is distorted (on different firmware on a miscellaneous, all the rest works, as far as it was possible to check.)

Give me, please, youк backup or at least boot.img, uboot.img recovery.img is should help, as settings of the screen somewhere in these files.
it is possible to lay out where - a thread or on mail [email protected]
Thanks in advance.
