Re: RCUnlocker

Attempted on a HP Probook 6450b. (2009/2010)
Able to read many exact checksum files from chip
Chip: MX 25L3205D

note about the error those are hardcoded paths not on my pc, is there an updated version of the tool or source I can compile from?

Any help is greatly appreciated.


Error dialog when running the unlocker:


zip with both before and after bins attached

Re: RCUnlocker

Your bios file unlocked.

Re: RCUnlocker

Your bios file unlocked.

I rewrote the new file and it still has the password on it for me. I'm using a CH341A with 8pin SPI clip.

Re: RCUnlocker

for chromebox unlock, changing the dev mode and enrollment set to 0 will not work. the only change is "requisition.remora.gbind. " to ".none.ubind.."


tried on chromebox 2 and 3 ASUS. both works.

hi! HP EliteBook x360 1030 G3 writes that it does not support(" Wrong chip try reading and unlocking 16mb chip"), in previous posts it says that it supports(Unlocking HP - ProBook, EliteBook, ZBook (including 32MB models) and Usage: Drag and drop .bin file to .exe file). Help please!

Maybe you have 2 SPI chips, usually it's on the other side of the motherboard, post both here.

Re: RCUnlocker

It was user error. I was able to get it working after another erase/flash cycle. Thanks Cheese

You are right, there are two SPI chips! The question is, is it possible to flash the firmware without full soldering? I understand, the program removes the bios password or something else? what are the capabilities of the program, what can it do? did not find information anywhere. Thanks!
I have two hp 1030. One has a password, the other has no password. Where there is no password, the program erases a certain area after analyzing before and after, the question is what did it erase if there was no password? ) Sorry for the large number of questions, I'm just learning)

Re: RCUnlocker

Anyone want to clue me in on how to use these probes I purchased from Ali Express?

Re: RCUnlocker

@Raiderman
Please upload one or a few good picture(s) of the probes, as it seems like we all left our crystal balls at home.

I will, its a page or two back that we discuss the using the probes for wson8 chips

[Raiderman]

Re: RCUnlocker

Yes thats a WSON8 chip, don`t use the clip on that,you risk damaging the chip,shorting the surrounding components and cutting through traces.

Your options are to desolder it,use a WSON8 pogo pin adapter,or try to solder some thin wires to the protruding solder or traces caps and resistors

These are the probes linked by SMDFlea that I purchased

Re: RCUnlocker

@Raiderman
I suggest to take a look at YouTube, use these keywords "pogo pin WSON8", I do get a few results there showing how to use the probe. I don't include the links here as some videos have advertising.

Re: RCUnlocker

how to remove computrace for HP elitebook 840 G6?

[AAAC]

Re: RCUnlocker

@ogre4273
Use UEFITool NE version and check UEFI Variables, there's usually one named AbtState, that one contains information if Absolute Computrace is Active.
Then use an hex-editor and search for AbtState, a few bytes before the string you will find the header AA553F(h), to invalidate that variable make it AA553C(h), save changes.

Re: RCUnlocker

A general question about flashing an image to the EC. Instead of patching the image in the ROM is it not sufficient to flash the ROM with the manufacturer's copy of the BIOS binary?

[RethoricalCheese]

Re: RCUnlocker

HP doesn't offer EC. Only main and even that is without ME region.

There is a way to make EC out of main but it needs some knowhow. I've succeeded a few times but would avoid it if possible.
