        thank you for your help, however after I finished recording, the machine could not boot, the fan did not spin, everything was silent. I looked carefully again and discovered that this laptop EC ROM and SPI ROM are separate, the file I uploaded before was EC ROM, now I will upload both EC and SPI files, hope you can help

            SPI file is corrupted.

                            Hello!
                            I wanted to post on the forum with a question about unlocking the BIOS, but during soldering, one of the EC ROM pins was torn off. The original EC ROM dump is permanently lost. I only have the original SPI ROM dump.

                            I replaced the original EC ROM GD25B256DYIG with a Winbond 25Q256JVEQ and flashed the dump from this thread. However, the laptop blinks 7 times and does not turn on.
                            I kindly ask for help in restoring the laptop’s functionality.

                                @Keg85 : Your version is T70, please find the correct version.

                                    Maybe someone has a suitable version for EC (bid T70)? I've tried many files from this thread, so far without success.

                                        Hi Everyone,

                                        I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                        The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                        the Computer is a Unowhy small pc

                                        My first attempt was to get the bios dump from windows...

                                        Hello,😇😇😇
                                        I need help unlocking the BIOS password on my HP ProBook 11 G2 laptop.

                                        🔒 BIOS Status: Locked with password

                                        The laptop is no longer under warranty and HP refused to help me.
                                        I’m looking for a custom SMC.bin file.

                                        I don't have a CH341A programmer, so it's difficult for me to provide a BIOS file.

                                        Thanks a lot for your help!🙏🙏🙏...

                                        Lenovo P14s Gen 5 SVP unlock
                                        by Syseng
                                        This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.

                                        The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...

                                        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....
