Could someone please help remove the password from the attached files?
I've attempted using the unlock tool, but it still prompts me for the password.
Attached are the files from both ICs and the unlock files as well.

Thank you for your help. I followed your instructions but encountered an issue. I received a message indicating that the BIOS blocks don't match and that I need to update the BIOS. However, when I reached the battery screen (the battery capacity error message due to the battery not being connected), the system froze.
Upon restarting the laptop, I observed six orange flashes and then nothing happened. I removed the chip again and compared the files, noting that some changes had been made.
Do you have any suggestions on how to proceed?Comment

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
Hi everyone,
I’m a student currently locked out of the BIOS on my HP EliteBook 830 G6. I bought the laptop second-hand, and the previous owner didn't provide the password. I really need access to the BIOS to change storage settings and boot orders for my studies.
System Details:- Model: HP EliteBook 830 G6
- Processor: Intel Core i5 (8th Gen)
- Serial Number: 5CG0080LKD
- Halt Code (from 3rd fail): qeh11u1kst
I'm hoping someone here can help me generate an SMC.bin file or provide a master password that works for this generation. Any guidance on how to get back... -
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,... -
Hello Hello,
I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!
I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.
