White screen problem make me crazy too.. It's no way to resolve the problem even I recently bought a new LCD screen and replace it, the white screen problem still persist. I hv tried many thing like previously what I was done, Erased Region 5, 43 and 48, unfortunately it can be erased but unable to write.
Does anyone know why region 5,43 and 48 unable to write ? does it has other way to write this region ?
