I have problem with firmware loop on logo.
Now when i upload new firmware on lcd have some strange stripes and loop at logo.
My old firmware was : "mt83x2_mr100z_mr100z1h1cw2.2015012216", can't find that one and i try upload
"MT83X2_MR100Z_MR100Z1H1CW2.2014122517" form .
Some one in comment write "Preloader file is broken" but i find second one "preloader_mr900" and try upload but nothing change.
Any one have that tablet and can upload for me firmware or preloader ?
