Hello!
Your bios chip is rewrite protected.
It can be bypassed by 3 ways.
1.Sleep Bug .Downgrade bios version to one of oldest versions.Set your laptop to suspended mode and wake up it after few seconds.
Then run tool again and look at result81.png. Red text still here?
2.Recovery mode. Very dangerous method, because user make all operations, one mistake so laptop is bricked.
3.HW SPI Programmer+Pomona Clip. Give 100% result, you can recover laptop after bad flash easy in every causes.

Please,do not post requests me in PM.Bios modding is very dangerous work.If i provide you confirmed modded bios, please donate for my dangerous work https://goo.gl/98BgtO.Thank you!
