You have Error 280 into your result file so Eeprom Chip Write Protect and not
moddable, only chance is to DOWNGRADE your Bios to version Previous and hope
that Eeprom came back unlocked so then You can flash Bios Mod !
Here You go :

So file you sent is one I would install after downgrading? How would I know if EEPROM becomes unlocked or not? What should I use to see if it is unlocked? Thanks

Cant find older bios to download and try to downgrade.. So Im stuck unless someone knows where to find older BIOS and knows a workaround that doesnt require soldering..

Ok I redone your Bios Mod so this is yours definitely :

P.S. I think W can try only to Recover your Bios Mod using Recovery Procdure
I will upload a Recovery Bios Mod based on your Bios Backup !

I am willing to try anything to unlock bios. Just need to know what to do.. I mostly mod desktop, laptops I just started. Laptops seem to be locked up too much!

Tomorrow . . .
