Hi everyone,

Thanks

[CammyTier1]

Please post your dump for someone to be able to unlock it

[tonipat01]

what do you mean by "dump", i forgot the bios password, now i cannot update the bios anymore, because the system required a bios password, i need help to unlock it. Which informations do you need please ?

You will need to read the bios firmware from the chip using a programmer and post the dump that u have done with the programmer here and someone will unlock the file for you
CH341A USB Programmer is a cheap option

Ok i see.

only flash this main do not touch the EC to avoid endpoint security controller problem.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
after following my instructions. flash back the original main and it's good to go.

Thanks for the help., @rex98 & @hoaca388., Now I simply am puzzled. @rex98 you are saying not to touch the EC Rom where as @hoaca388 gave me a updated copy of EC Rom. Kindly inform me what to program back again. The Main SPI ROM or the EC Rom??? Get me out of this confusion. Thanks dear.
