[REQUEST] HP ProBook 4525s Whitelist Removal

[BDMaster]

All ProBook series Laptops are Blinded by RSA Internal Check !
I am trying on a ProBook 6440B and none modify is possible I just tried a text mod
and produce a Brick !
Now We are going to check where is placed the RSA control as It has a PEI different
than Donovan6k exposed !

Thanks for the answer. I saw an active thread with Probook 6440b. I programming available, my laptop is an exploded view, and I also can serve as a guinea pig, if it will help the process of breaking RSA.

With best regards ))

Ok mate,
Your Bios is rewritebale only using an SPI Programmer + Clip, but the Bios Mod is been
tested and so working !
If You get the Tools then I will help You !
Let me know

So SPI programming is available on weekdays to me once a day)). This means that now I can try to flash the BIOS-MOD in the traditional way. If there is a brick, then September 21 I can use SPI programmer and put the BIOS version F.09 dump again. Immediately I could try the following BIOS mods, and in case of failure to return immediately dump F.09. Next time I will be able to use SPI programmer September 22, etc.

I'm ready ... I'm waiting for further instructions))

Ok mate,
You have to read the Firmware from your laptop Eeprom Chip then upload It here and I will
patch for You !
So You now can do this . . .
Use this tool run It as Admin and upload here the result file :

http://rghost.net/7GBZt7FVt

http://rghost.net/53128665

Use AIDA64 tool too (cracked version to get FULL REPORT) and upload a Report too

let me know
Regards

In this way I will look your Bios Region and version then I have got time to patch about RSA
and NWL too !
When You will upload the firmware relative to this Bios version I will patch It quickly and
reupload in few minutes !
Let me know
Regards

P.S. tested one all Others will works surely !

Dear BDMaster!
I already have a dump with my laptop BIOS version F.50 (last from site HP), read using SPI programming. However, according to HP:

Provides improved security for UEFI EDK2. HP strongly recommends transitioning
promptly to this updated BIOS version.

NOTE: After this BIOS update has been installed, previous BIOS versions cannot
be reinstalled.

So I would like to know whether it is possible to patch this version of the BIOS or better to use as the basis of an older version of BIOS F.0A? F.0A easily recorded patched HPQFlash.exe utility version 4.30 ...

If an older version of the work will be easier, I'll update the BIOS to version F.09 to F.0A. And then, to dump and a full report with the help of the program AIDA64.

Is there a difference in how to do the dump, the program that you have offered to me or directly by SPI programmer?

My dump F.50 (by Programmer):

Update to F.0A:
F.0A Full Report and Dump, made by your utilities and AIDA64:

No I think It's same thing so let's try with your last Bios !
we can Downgrade to any version using SPI PGM I will prepare the Firmware
and You can rewrite going to any version do You want to try !
If You have the version F.0A read by Programmer then let I get too !
Can You let me know which Eeprom Chips are on your MoBo ?
You posted a Firmware which is only Bios Region so missing Descriptors and ME !
Let me know

I can update to F.50 again, if it need. And then I do this reports again.

Here You go v.F.50 RSA Patched + NWL :

I will donate to you, dear BDMaster, but a little later, when I get a salary (a few days)))). In any case, I spread the same report and dump, but for version F.50, then update ... Maybe something will change ...

I can test the firmware on Monday, when I will have a programmer, and be sure to tell you about the result.

I am very glad that there are such wonderful and helpful experts in their field, like you!
