Re: HP BIOS unlock tool
Hello, I tried the tool for an HP 470 G5. I flashed with a CH341A into the chip (25B127DSIG I find no datasheet about it), but the Power-on Authentication still appears on log in.
Could you give a look to my original bios bin?
Thanks in advance

Re: HP BIOS unlock tool
Hello again, I read through this thread and came up with all of your comments. You are right, this section also needs to be replaced from a Non-locked bios to remove the Power-On Authentication. For my bios dump I did the following:
1. Use the HPUnlocker_v1 tool to create an unlocked .bin.
2. Open this unlocked bin file with HxD Editor.
3. Search (Ctrl+F) for the keyword "UserCred" as Unicode. Note: In my case this appeared three times, but only one of them is the section needed.
4. Select from the beginning (Starting in 55 00 73 00 65 00 72 00) until the flag "AA 55" appeared. This was of length "DE6" (hex) or 3558 (dec).
5a. Open the empty file provided by peste and select/copy exactly the same section as in the previous step.
5b. To make it easier for anyone, I attached the template as "empty-user-power-on-template.bin", so you only need to copy it directly, instead of doing step 5a.
6. Paste write (Ctrl+B) the template into the selected section from step 4.
7. Double check that the file has the same size as before replacing the template. (Ctrl+A), in my case the length was 1000000 hex.
8. Save it as a new bin file.
9. Flash this file into your chip. (I used flashrom in Linux, I can really recommend it)
10. On booting i found a "Post Error" saying the memory size is different from last time, i pressed enter. Now there is no password on boot nor on bios!
11. Just to make sure, go to bios > security and reset the security to default.
I hope that is helpful for someone in the future. If more people can confirm this method it could be possible to automate this process inside the HPUnlocker tool, right?
Thanks to RethoricalCheese for his tool and to all the guys posting here!Attached FilesComment

Re: HP BIOS unlock tool
we ask you if there is another bios chip on the motherboard, apart from the 33MB one, it is usually on the other side of the motherboard compared to the 33 mb one and it has 16mb..if you don't have another chip try this. ..if the password does not disappear, then the password is in the I / O chip ..Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
Hi all.
I'm looking for a BIOS file for an Asus N550JK.
I have a Asus R552J, which I believe is identical to the Asus N550JK.
I downloaded the latest BIOS (210) for the R552.
It is named N550JKAS.210.
The BIOS file is however only 6mb in size.
I've read the chip with a CH341A programmer and verified the file.
That file is actually 8mb in size.
I'm wanting to remove the BIOS password from this unit.
It prompts you to input the password when turned on, so its sort of behaving like a power on password rather than... -
I have a problem with the BIOS for a HP Pro X2.
What I try to do is to load a new file to the MX25L12873F chip.
I'm using the RaspberryPi to read/write to the BIOS.
I connect the BIOS to the RPI as below, I have succesfully used this setup many times before.
Before I started I saved the current BIOS three times and compare the checksum, without any problems. Then I downloaded and extracted the new BIOS bin file. But the new file was smaller than the original one.
Error: Image size (9437184 B) doesn't match the expected size (16777216 B)! So i added some... -
Hello,
I updated my pc, from Evga z270 itx to Asus b660-i itx motherboard. In my old z270 motherboard everything whas easy because everything in bios was unlocked (fd, me etc), and could do everything I want.
Now in my Asus b660 everything is locked (except main bios region). I dont mind so much but I want to unlock bios so I can flash a new splash screen (I have done it with my old motherboard).
I made a bios dump with FPT (fptw64 -d mod.rom -bios), I modded it and I tried to flash back
(fptw64 -f mod.rom -bios). I got Error 167: Protected Range Registers are currently...
