Hi
I have a bricked motherboard Gigabyte z170 Gaming 7 with Dual Bios chipsets MXIC MX25L12873F M2I-10G.
After of a wrong Intel ME firmware upadate I have continues boot loop (monitor never wake up-always off) with the last post (before loop) motherboard error code "b2".
I try everything to backup main bios from back up but never worked out.
Before i try anything with programmer …If i manage to solder Backup bios chip in Main bios chip position it will boot up?
@bloodmaster - Do you still need help with this? Sorry I missed your post until now 
No soldering is needed to fix this, you can do it all with FPT program. Tell me your MAC ID and I will send you BIOS and info how to fix with FPT
exact same problem. Please help.
Dont solder a new CMOS chip in there, solder a socket so it doesn’t happen again, gigabyte gaming series motherboards are well know for self bricking themselves.
