After I flash back nand.bin, I got 0020 RROD. I found out that when I was flashing, another tiny wire came out from the wire soldered on the front board(which power button,light riing are on). and that tiny wire touch the next solder point on the right. I think this cause the problem. My board is Zephyr. Actually, It powered on and was once working fine, but I took another read nand.bin and compare the one I put in, there are not exactly the same, So I took another flash. It got 0020 RROD as I explained the wire condition. Any one have any idea?
