    The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
    first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
    use BCU and put your original DMI.

                      For two days i am trying to get the notebook to work as it should. the password is gone for sure but i am getting constnt errors. it boots every other time. when it doesn't, it seems like it doesn't see the ssd. in device manager i had an I2C "cannot start" error, after that "intel smart sound technology OED" with "FW did not sent FW ready notification" and when i try to update the bios, it doesn't do it. the boot fails, restarts then enters windows. i even wrote the original bios file back but still same errors. what to do next please?

                                        Hello,

                                        I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                        But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                        I'm trying to reset my bios without success.

                                        I tried :

                                        -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                        by Nopslide
                                        Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                        My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                        Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                        1. I bought this laptop from flea market, and the seller said that he had never set a password, however here is a password required when pressing F2 to enter BIOS.
                                        2. And after entering incorrrect password 3 times, there is no any useful information like "recovery code"
                                        3. I used universal bios backup tool, and dumped 8MB bin file, but hex code after "SystemSupervisorPw" is...
