fastboot flash partition gpt.bin

For those who are stuck at bootlogo, the problem is the same as the one when we tried before downgrading from 4.4.4 to 4.4.2 it is with the partition table, the version in the ota is older that the one we have on our devices, I dunno how the hell is that but it is what happened to most of us, though the easy fix, flash the attached gpt through fastboot command:Hope this fixed everything
