I had purchased a bricked c760 (2 bad NAND blocks) for the screen. I did swap out the screen to use for my c700 and I put this one aside..
I found out how to fix the screen so I put it on the bricked c760. I decided to tinker around with it and I did a NAND erase and was able to flash it back. So now the c760 that I thought was bricked is working!
This is great! the c760 works so much faster than my c700 (stupid PXA250 processor.. )
