I can't find switch option from TPM 1.2 to 2.0 in Secure Chip Tab. I have installed Windows 11 on original Bios, some time ago, but on UNLOCKED I just can't find this option. I checked ME CONFIGURATION, but this way made changes doesn't save. I put orginal BIOS again, and BETA version works fine. Regards

Hi!

Ok. I checked your file bios dump, unfortunately it's not correct. You need to read your bios dump from your bios chip again, 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/w4kvs2pqa

I recommend you use software AsProgrammer_1.4.1

I tried 3 different programmers and all the saved files look identical.

Thank you in advance.

 

Keep up the good work.

Hi, do you know how to downgrade Thinkpad X240 the BIOS from 2.49 ? It seems reflash via programmer is the only option, isn't it ?

I installed 2.49 (lastest BIOS) and battery significantly reduced. The uncore power was very high (almost 3W), I found noway to reduce this uncore power to normal (< 1W).

But when I try to downgrade BIOS via Windows, it does not work. I tried to run command Winflash64 /sd /file but it does not work either - it works on x230, not x240.

Sorry for my English, it is not my native language.

Hi!

Try to use this instruction:  

 

Also, try to disable in bios setup menu:

  • Disable Security Chip
  • Disable Anti Theft Module
  • Disable TPM

Also, try to go into your BIOS setup. Navigate to Security -> UEFI BIOS Update Option. Set Flash BIOS Updating by End-Users to Enabled, and Secure RollBack Prevention to Disabled.

 

Also, try to use command:  winflash64 /sd /file X240.FL1

File X240.FL1 you can download from this link:  https://files.fm/u/vn2j7h3nx

      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.

      Hello guys 
       
      I've got a pretty weird problem with my M18x R2. I already searched the web but couldn't find an answer. A few days ago I changed some settings in the bios, if I remember correctly DMVT Pre-Allocated.
      After saving this setting the notebook refuses to even POST. I get no beep errors or anything. If I press the power button the system turns on, the leds turn on and then the system shuts itself off. I already reset the cmos, the IME, tested different configurations and so on. If I remove all the memory sticks I actually get the memory error code. At this point I'm pretty sure that the bios got corrupted for some reason when saving these mentioned settings. Did anyone had a similar problem and got a solution for this? I repaired lot's of notebook but never had an error like this...
      The Bios installed is the a15 unlocked.

      Is it possible to unlock bios on that model? Please help me with it if somebody can.
