Hi Klem! I've linked to my T440p binary---any help you can give me would be greatly appreciated. I got stuck when trying to patch the file, so I was glad to see that this thread was still active. :)

I'm hoping to remove the wireless card whitelist and enable overclocking/undervolting.

 

Thanks!

Hi,

I'm Brazilian, so I'm using a translator.

 

I have a ThinkPad T440p, with bios version 2.55.

 

I would like to remove the Whitelist in order to change the wireless card. can you help me?

Would I be able to provide a bios without the whitelist for me to rewrite here?

 

Thank you very much in advance.

Hi!

As first step, you need to read your bios chip with hardware SPI-programmer and get your bios dump. Just read the first post of this thread.

Hi, thanks for the reply.

I backed up my notebook's bios. I read and saved the bin file.

Could you unlock whitelist so I can change the wireless card? If possible, unlock the advanced menu.

I put on mediafire the link to download.

thank you so much.

Hi!

Ok. As first step, you need to read your bios chip with hardware SPI-programmer and get your bios dump.  You need to read your bios dump from your bios chip (using hardware SPI programmer, how to do it, read the first page of this thread), may be multiple times and compare in any hex editor (for example HxD), all dumps should be identical.

If you will meet with some problems with read bios dump from your bios chip, then try to use different software version.

All software versions for Ch341A programmer I placed into this link:  https://files.fm/u/vchnhg37k

I recommend you use software AsProgrammer_1.4.1

Hi!

To unlock your bios, you need bios dump from chip named MX25L3273E only. But I recommend you to read and save the dumps from both chips, just in case.

Ok. Check PM.

Klem.  I was using an unlocked BIOS from you on my T440P without issue.  However, I somehow updated my BIOS firmware on accident and now its locked again.  Would you be so kind as to help me unlock it again?

      Clevo P150SM(-A) Prema Mod
      By Zauih840
      Hello, as the title states, I would be very happy if someone could give me the link to the mod, apart from that, what version should I install?, as I've seen that some models have v1 and v2.
      My other questions are: what do I have to do to install a new GPU?, (9xx series)
      And what mods do I have to use to have a 10x0 series (and which are compatible).
      I have the Clevo P150SM(model)/P150SM-A(product code) (2 models on the sticker) with stock bios (it says copyright 2012, so I guess it's the 1st version) with a 4710MQ and 870M.
       
      I would be very pleased if someone could hand me the link.
      Many thanks in advance.

      Lenovo B570e - help with unlocking the whitelist
      By biuro74
      Hi,
       
      So I've landed here to get some help with unlocking my old laptop. I must confess I've done few mods before, but it was on PCs, so was a piece of cake - adding Xeon to supported CPU models, or updating OROM to get a system boot from RAID SSDs. But now I'm trying do "the same" with laptop first time and this is a nightmare, mostly due to multiple BIOS vendors/methods, each of which requires own tools, some works with older revisions, some don't, some require 32-bits, some don't, and all YT examples being done using various configs = so in the end: a mayhem.
       
      My laptop config is:
      Lenovo B570e, i5-2520M, 10GB RAM
      BIOS: 44CN43WW (latest, unmodified), SMBIOS 2.6
      Phoenix/EFI SLIC Mod indicates it is an EFI/Insyde BIOS, but entering the BIOS I've got "Phoenix SecureCore Tiano" info
      WLAN: original damaged, a replacement (by chip) doesn't allow laptop to start - Error 104 Unsupported wireless network device...
       
      All I've found so far was:
      * Universal BIOS Backup Toolkit 2.0 - to make a BIOS dump file (succees)
      * UEFI Tool - to load dump file, search required module and extract it (success)
      * WinHex - to search an assembler code boundaries, and extract it (WinHex will not save edits = unregistered version), so semi-success
      * Hex Editor Neo - to disassembly code, and probably make changes (so far: in progress:))
       
      And I've stopped at searching the JZ/JNZ mnemonics, probably this is because I've got wrong code boundary (from WinHex), which gives improper disassembled program in preview pane. What I'm looking for is a loop, which I try to obey - regarding to some "popular" links describing this method (unfortunately I can't follow these instructions 1:1 as some programs don't work as supposed and crash - like WinHex, yup, some don't work at all and I need to use different tool).
      One more frustrating thing is I can't find proper tool for final stage - which is good (working) flasher. I can't remember how I've reflashed BIOS previously - must have been years ago - but now PhoenixUEFIWinFlash makes a BSOD (original, executable BIOS downloaded from Lenovo support website uses this program, which shows its GUI for a moment and makes BSOD), and "external", latest Phoenix UEFI WinFlash program doesn't want to work properly at setting up stage. Probably I will have to use phlash16 and FreeDOS, but will see at the end, when I have modded BIOS completed.
       
      Any suggestions (or even better - some ready, modded file), please ?
       
      Thanks in advance for any help, I appreciate any clue.
