Removing Wi-Fi Whitelist on Haswell Thinkpads (T440p, T540, W540) & Unlocking Advanced BIOS Settings

[@WolfgangsChannel]

PSA: Check the 3.3V rail on your CH341a with a multimeter to make sure it actually outputs 3.3V. "Wait, haven't you posted this video already?" Yes! I've already made a tutorial on unlocking the BIOS on T440p. However, part of the tutorial involved sending the BIOS to an anonymous person from an online forum and paying them to mod your BIOS. That video is now unlisted. After uploading the video I've been approached by Stefan Schmidt (Thrimbor), who shortly afterwards developed and released the patches that unlock the whitelist. In this video I describe the whole process from A to Z, including patching and signing the BIOS file (no 10 beeps on startup). You can read more on the methodology and development of the patches on Stefan's blog: thrimbor.github.io/2019/09/24/removing-the-m2-whitelist-on-a-thinkpad-t440p.html The BootGuard bypass method as well as the patches unlocking memory settings and the advanced menu were developed by XX and paranoidbashthot paranoid.anal-slavery.com

Super spannendes und schön gemachtes Video! KZbin hat leider viel zu wenig ThinkPad-Content und gerade die Mods, Frankenpads und kleinen Bastelprojekte finden fast nur in Foren statt - wobei die Foren leider auch immer ruhiger werden. Es freut mich daher sehr, dass Du diese spannenden Themen hier in unterhaltsamen Videos präsentierst.

[@tylerwatt12]

Here's info for the T540p: specify the chip name when reading or writing using flashrom, like: sudo flashrom -p ch341a_spi -c "MX25L3273E" -w xxx.img Do not modify xx_40_patches_v7.txt, and it will patch just fine. The T540p relies on the patch for the W541, as well as the T440p to work. I've installed an AX200 with no problems. Also, you will have to take apart the entire laptop to reach the BIOS chip, It's the lower chip, further away from the SIM card slot. Everything else is done as the video shows.

[@vonniehudson]

Hey Tyler, where exactly is this BIOS chip on the system board? I’ve disassembled everything except the heatsink and fan and can’t find it even under a magnifying glass. I have the W541.

[@albdr88]

Used this guide to re-flash the BIOS. All went well. I wasn't too confident of the clips fitment onto the BIOS chip. Also, I thought the 'pip3 install pycryptodome' was for Mac users, as my package manager had a python3-pycryptodome package, however after wasting some time wondering why I couldn't sign the BIOS image, I learned installing pycryptodome through pip3 is necessary on Linux too.

[@michelemarrazzo4167]

Just to share my experience doing this, I had my bios version at 2.54, and just to be safe I downgraded my bios to 2.52 to avoid any compatibility issue with the patch. Just check in your bios that option that allow user to downgrade the bios. In the lenovo t440p website you can download and downgrade any version you want, download 2.52 bios flasher and let the sw do the job. In my case it freezes my computer (panic!), after 10 minute I pressed the power button once and it unlocked by itself. After that It resumed the procedure and reboot, and later successfully downgraded the bios. After all of that, I just followed the nice guide and worked flawlessy. The first dump and diff I had was not good, and noticed my flasher usb port was not soldered properly, a drop of solder solved my issues, and everything went fine. Just don panic and everything will be ok.

[@baptistecroissant475]

Hi guys, it is said in read me (bios 2.5x text file) that it is not possible to roll back to any previous version. Could you detailed the option you changed to allow downgrade ? I tried the tutorial yesterday using 2.55 bios version and ended with a beeping computer. first the t440p started fine but no internet connection was available (original --> BCM94360NG wifi card swap) just like if no card was present. I will open it again and verify if cables are still connected but it would be strange that they disconnected. Then I restarted the computer and it beeped crazily. First time doing bios flash and using terminal command. I might have done something wrong with files/folders location as text/folders names changed since the video upload --> even if all signing /verifying / flash were validated in terminal I will try to reflash original 2.55 bios, then downgrade to 2.52 as you did and try again

[@michelemarrazzo4167]

@@baptistecroissant475 I found that option under the tab Security-> UEFI BIOS Update Option-> Secure RollBack Prevention "Disabled". Before I don't think I had any special BIOS with this option, so this should do the trick. If you have a good binary of the stock bios, just flash it and you should not have any problem to let your pc live again.

I want to add that I don't have never tried to use a different wifi card, because someone has done a kext for the intel card, and it works really well.

Hello Wolfgang, first, thanks for the awesome Video. I have a W540, where I wanted to install an AX210 WiFi Card. So I went trough all the steps in your video and your written instructions. Everything worked out well. So thought I.... I read the BIOS file, verified it, literally followed your steps 1:1 after watching and reading it like 3 times in a row, just to make sure I get everything 100%. I then patched the BIOS, signed it, verified it (successfully) and flashed it back to the 4MB Chip on the board. W540 is a pain in the bu** as you have to completely disasselmbe the whole Machine. There are also 2 Chips, one 8MB, where the patch does not work (I tried :D) and the 4MB on which the patch works. EDIT: I just read on the pinned comment, that I must apply the patch on the 8MB chip, and not the 4MB Chip, that's for the W541, should be the same for the W540. Anyway, I tried to patch the 8MB Bios file, but then I get a simply and unhelpful "Error" from UEFIPatch. It worked perfecty on the 4MB Bios file. When I then reassembled the machine, it POSTed with the same whitelist error as before, but interestingly, the modded BIOS with more functions was completely there and functional. So looks like one function of the patch worked, the other one did not. I'm honestly clueless. I'm also taking myself out of the "possible errors". It's not my first time stripping laptops or phones completely apart. I'm also extremely picky and cautious with my disasselmbe and assemble processes. So, with me being clueless, does anybody has any helpful advise? I can't believe I'm the only one having this issue... Thanks a lot!

Coreboot is now on the W541 (and probably the W540) as well so try that out too. Dedicated graphics don't work but everything else seems to. Takes a bit to cold boot too, it seems like the more RAM you have the longer it takes

[@OnliDM]

I made the experience following this guide that my Thinkpad did not boot after flashing the bios. And a reflash with the original was not possible because somehow the mentioned adapter in the video does not support QSPI Mode (as it is recommended in the manual of the bios chip W25Q32FVSIQ) for flashing this kind of chips. And even if you use a more appropriate programmer for this like I did (TL866 II Plus from XGecu) you won't be able to write to the chip through the clip. You actually have to solder out the chip, solder it on an adapter and flash with the programmer soldering it back again afterwards. Only this option fixed my Thinkpad to boot again (with advanced bios options and removed whitelist). Another additional point is that the mentioned programmer uses non appropriate voltage for writing these kind of chips. I was also in a long exchange with Klemm on this Topic. So there are many thinks to consider when you want to do this. (Soldering that kind of chip can crash your motherboard easily within seconds, because there is not a lot of space for the heat to concentrate only on the chip and you are always heating the around lying components which can cause them to melt) I like what Wolfgang is doing and I took it a way further the inspiration if you are interested in the modified heatpipe that's my "franken" version of it :) www.reddit.com/r/thinkpad/comments/g8a291/challenge_accepted_a_dual_heatpipe_heatsink_for/

[@saprish9363]

I can confirm that this works on a T440. The only change is to not add the last step for the signature, the device will not boot the OS if you do. The 10 beeps are present, but do not go off every time the device is rebooted; I'm not sure why but I can't be bothered to investigate. Good luck to anyone that attempts this, and be sure to back up what you can't afford to lose. Cheers!

Great video! However there is one detail missing, with MX25L3206E chips writing/reading may be unreliable, if this happens it is needed to supply extra power to the chip, this can be easily done by plugging in the charger and ethernet cable. The GBe mac address is stored in the SPI rom along with other parts of the firmware, the 3.3v rail for the SPI roms is powered from the rail for the GBe. Making the machine wait for Wake-On-Lan powers this rail on.

True. Have to say though, I've tried the WoL method on X230 since I've heard it's safer than supplying the power directly to the chip, but it never worked for me. CH341a with a pre-wired SOIC-8 clip seems to be much more stable than an RPi + a hand-wired clip.

Is there no such solution for Thinkpad P53?

[@volodymyrhladun153]

Can you tell me what the problem might be? I made a modification according to the instructions - the advanced menu works, but the wifi - intel AX200 does not work, that is, the white sheet did not turn off ... Is there a chance to fix this? laptop Lenovo T540p

Good video. By the way, could the x240 or T440p accept the new AX200 wifi card ? Thanks.

[@WolfgangsChannel]

I haven’t tried, but in theory it should work

[@brum2302]

@@WolfgangsChannel I have now tried the AX200 wifi card in the X240 and yep, it didn't work. So now, i have ordered the kit to flash the BIOS and remove the white list. Will post here if that (remove white list) works for the AX200 wifi card:)

[@WolfgangsChannel]

@@brum2302 If it works, it will work for all the cards. The question is whether it's gonna work for X240. As of now, there's no official support, but you can try the T440 patch

Hi @@brum2302 could you tried the whitelist removal on the x240?¿

Hey, I have gotten to the part of patching the bios but it keeps coming back with 'Function called with invalid parameter' on MacOs Catalina and can't figure out what I'm doing wrong, I am using the latest xx40_patches_v7.txt. Anyone know how to fix? Thanks! Edit: Fixed it, turns out the first link for the patch didn't work, so tried the mirror and that worked fine!

[@emuhill]

If you have a Raspberry Pi you can use it as the eprom programmer too. You just have to get the clip and use a tutorial on how to wire up the clip to the GPIO header pins. You might need to install some stuff on the Raspberry Pi too in order to get this to work. After that everything else is the same.

Wolfgang´s, How to enable the CPU Lock Configuration menu to enable CFG Lock? It was not possible with this patch, is there another one?

[@impermanenthuman8427]

Slightly related question...would the latest USB port WiFi adapters be ‘faster’ (better bandwidth?) than the built in WiFi adapter in the W540? Also would plugging it into a usb 3.0 port instead of 2.0 make any speed difference? Thanks

[@WolfgangsChannel]

Absolutely not! PCIe cards are faster and provide better signal (AX200 has maximal speed of 2.4Gbps) There are USB WiFi adapters that provide comparable speeds, but they're expensive and have a clunky design (external antennas, bulky housing, etc.)

[@impermanenthuman8427]

Wolfgang's Channel thanks for the answer 👍🏻

I can confirm that this works for the latest bios version 2.55 on Lenovo Thinkpad T440p

[@bungles300arms5]

I Just rebuilt a 540p with the 3K screen added a kingsener aftermarket battery, (similiar battery worked great in my T430) it won't charge, it just sits at 49% charge on the battery (although it must be charging to maintain the 49% level) does anyone have the same machine and know if there is a battery whitelist in the BIOS? My bios version is GMET56WW 2.04 . I can't even perform a bios update (not sure I should do that anyway) as the lenovo utility doesn't recognise that the AC power is connected even with the battery removed and the bios utility running!

[@joskobacic4084]

Could you help me find patches for Lenovo G500? (with the celeron 1005M, from 2013.) I wish to upgrade it with an i7 3630QM, but the forums say it has a CPU whitelist also removing the Wi-Fi whitelist would also be nice. Thank you very much in advance.

[@replica9000]

Silly question: Couldn't someone apply a patch to an update file and flash it like a normal BIOS update?

[@WolfgangsChannel]

I think the issue is that the installer verifies the checksum of the BIOS file to make sure that it was downloaded correctly.

Hi, in my W540 there a two BIOS Chips. Do you know which one I have to modify?

I noticed you were using OSX for this. If I use windows command prompt will the commands be the same or will it change a bit?

I don’t recommend using flashrom with CH341a on Windows since it requires installing unsigned device drivers. You’ll also need to substitute „flashrom“ with „flashrom.exe“

I'm getting the following message when I execute the signing command: ERROR: Could not find FFSv2 volume GUID - I even tried a bunch other bios files but same message. I'm using ubuntu 18.04 and I'm pretty sure I followed everything to a t, any ideas? EDIT: I foolishly tried to do this with a T450s bios which just ain't gonna work. I tried it with a random T440p dump file and it worked. For the T450s, I can eliminate the beeps but I also lose TPM functionality. Waiting for a free signing tool for the T450s, if one will ever come out, free or paid.

Is it possible to remove the whitelist for batteries in lenovo thinkpad t440p?

[@WolfgangsChannel]

Not that I know of, and I personally wouldn't recommend using knockoff batteries as they tend to have lower capacity and don't last as long. On 30-series Thinkpads it made sense to get rid of the whtielist because it prevented you from installing original 20-series batteries which were otherwise fully compatible. But here, your only other option apart from original batteries is Chinese knock-offs.

I read on some Reddit post that you can downgrade this Bios (2.52) to version to 2.36, which has no whitelist. Unfortunately, it cant be done with Bios >= 2.53. In case it can be done. Would there be any downside of doing the downgrading?
