      Sorry i didn't see you already did upload ...ok here are the steps now password is gone no need to do anything else with your file just reflash it and follow my steps after you do so or the cloud will reset it again once you go online.
      steps:Make sure to do this steps after reflash:
      Resetting NVRAM
      i) Shut down your Apple Mac.
      ii) Locate the following keys on the keyboard: Command, Option, P, and R.
      iii) Turn on your Mac.
      iv) Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
      v) Hold these keys until the computer restarts and you hear the startup sound for a second time.
      vi) Release the keys.
      And after that... reinstall the OS is a must to have no other problems.

                    by unionjam
                    Hi friends,

                    Please could someone help me with my BIOS lock ?

                    I unsoldered MX25L6473E bios chip from 2015 board and read data trought CH341.
                    Now I have bios dump hex.

                    SN: C02R3XZHFVH5

                    Can someone send me working bios please?
                    Thank you so much.
                    Tom....

                    ASUS TP500LA BIOS request/repair/merge?
                    by jbonavita
                    Hi, my laptop wont boot at all
                    With original bios no POST, only LED lights
                    With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                    Some issues
                    A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                    B- If updated from 500LN version 203 to 300, the battery stops being recognized

                    Things I tried

                    1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                    by zenius
                    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
