HP SpareKey issue with my HP Spectre x360

Re: HP SpareKey issue with my HP Spectre x360

Oh, well, I read scancode and explained the scancode method didn't even look at where that password came from. Good job!

Edit: Yup, this is the AMITSESetup method, which I've explained somewhere else before. I've quickly made myself a tool before fir AMITSESetup but would gladly take a look at yours.

Re: HP SpareKey issue with my HP Spectre x360

You would need to find where the password is (I don't really know how to explain how to find it so you would need to find it yourself). It is in hex, first character is the length of the password (for example 0A would be 10 characters long). Next characters are the password itself, except the last character, which is checksum.

Password is in scancode format. Google for a scancode table so you can "decrypt" the password.

This is an example:
05080606030BD9
Password lenght 0x05 = 5 characters
Password 080606030B = 75520
Checksum = D9

I think you may have confused your explanation in this algorithm a bit, but that's okay... The important thing is to be nice, this quality is not lacking in you. Congratulations!

Because spectre is not probook/elitebook/zbook.

Your password is prot8200

@RethoricalCheese
How to get this result, could you explain this scancode to the community?

Re: HP SpareKey issue with my HP Spectre x360

Hi,

I am new here.

Need your help with similar situation.

I am using EZP2019+ programmer.

The bios chip is 25B64CSIG, assume the manufacturer is Gigadevice since the "CSIG" type keywords come after their produces.

However in the EZP2019+ this is not listed under their brand. How can I add the missing chip in it's library. could someone please help.

Or the compatible chip ID from the below list.

Re: HP SpareKey issue with my HP Spectre x360

I don't think HP sets any passwords. Only on demand by whoever orders these laptops. I just read it from your bios dump.

Re: HP SpareKey issue with my HP Spectre x360

I can't thank you enough.

Is this HP's default Administrator password ? because it doesn't look like anything I've used in the past

Anyways, it worked perfectly well, and I was able to reset both the Administrator and Power On passwords successfully.

Thank you all for your help and support. This is a wonderful community.

Re: HP SpareKey issue with my HP Spectre x360

Hi @SMDFlea

I have an update to share.

So I used the HP Unlock Tool to generate an unlocked version of my bios.bin file. I erased the chip, wrote the unlocked bios.bin, and verified that the image was identical to the chip's memory.

This is what happened when I switched the laptop on:

- Caps Lock button blinks 3 times quickly;
- then laptop powers off and powers on;
- then Caps Lock button blinks 5 times slowly;
- then Caps Lock button blinks 3 times quickly;
- and continues looping the blinking sequence on and on.

During this whole process, the screen's backlight is always off and never powers up.

Luckily I had made several verified backups of my original BIOS, which I was able to successfully restore and get it to start up again but unfortunately the laptop continues to ask for the password.

This tells me that the BIOS reading / writing process works, but it seems the HP Unlock Tool somehow messes up or corrupts the BIOS image.

If you could help, I'd really appreciate that.

Thanks again.

Hi @SMDFlea

Quick question, I'm trying my luck with the HP Unlocker Tool, and it seems to have successfully generated an unlocked version of my bios.bin file. Do I need to erase the chip using AsProgrammer first before writing the unlocked bios.bin file ? Or can I just overwrite the chip as is ?

Thanks

Re: HP SpareKey issue with my HP Spectre x360

I just got my new CH341a and was able to run three read / verify tests to ensure that the chip is detected and read correctly. Here are the results:

Current programmer: CH341
ID(9F): C84017
ID(90): C816
ID(AB): 16
ID(15): 2020

AsProgrammer automatically identifies the chip as GD25Q64B, but as instructed, I manually set the chip type to MX25L6473E

1st Read
Execution time: 0:01:07
CRC32 = 0x45897089

2nd Read
Execution time: 0:01:07
CRC32 = 0x45897089

3rd Read:
Execution time: 0:01:06
CRC32 = 0x45897089

I've attached the BIOS dump as requested. Appreciate your help in removing the Administrator / Power On passwords from it. Please let me know if you require anything else.

Thanks again for all your help and support with this.

Re: HP SpareKey issue with my HP Spectre x360

ok , no problem .

Re: HP SpareKey issue with my HP Spectre x360

I tried resoldering all the pins on the ch341a hoping it would fix it, but it still doesn't work.

In fact, if I leaving my ch341a plugged in my PC's USB port for 20 seconds or more, it gets super hot, you can literally fry an egg on the pcb.

I don't want to damage my desktop's USB port or short its motherboard. I'll wait for the new ch341a to arrive before I continue with the BIOS dump.

I can't thank you enough for all your help and support.

I'll report back once I've successfully dumped my BIOS.

Re: HP SpareKey issue with my HP Spectre x360

Its better to desolder it if you can. I`ve got three ch341a`s ,one with a blue pcb,the other two green.Both green ones were DOA ,resoldering all the pins brought them both back to life .

Re: HP SpareKey issue with my HP Spectre x360

The CH341A doesn`t support the 25B64CSIG .Use AsProgrammer software instead. That doesn`t support the 25B64CSIG either but does support MX25L6473E, its cross compatible, change the hardware to CH341A,then choose the (MXIC) MX25L6473E from the list .

Thank you for the instructions. I just found out my CH341A is damaged. I ordered another one which should arrive in a week. Will post my dump as soon as I get the new CH341A adapter. Do I need to de-solder the chip prior to dumping it ? Or can I just dump it using the Pomona Soc8 clip while it's still soldered to the motherboard ?

Re: HP SpareKey issue with my HP Spectre x360

Ok great. So we've been able to identify which chip needs to be dumped. So now, I just need to attach a dump of this chip ? Or are there other chips I need to dump as well ?

[SMDFlea]

Re: HP SpareKey issue with my HP Spectre x360

Please find hi res photo of requested chip.

It's:

BH61A
25B64CSIG
P13192

Thanks for your help.

Thats the one !

Added datasheet.
