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

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!

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.

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]

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.

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.

[@StefanHolmes]

Many thanks for this video. Successfully performed the BIOS reflash dance on my T440p today. Your comment about "if it says it can't detect the chip, try re-connecting the clip" was 100% on the money, because even though I thought I'd got a really good connection on two attempts, it wasn't until the third that flashrom actually worked to read the BIOS. Reading the BIOS took 35 seconds, which was a bit nerve wracking. Now I just need to find out what all those new BIOS menu options mean.

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!

[@digm0repaka]

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.

[@WolfgangsChannel]

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.

I rarely comment a KZbin video but this one really deserve it ! Thanks a lot for you work, I managed to flash the BIOS of my T440p without trouble (just did 5 BIOS dump versions #Paranoid) !

[@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/

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.

Why does sudo create conflicts with the package manager?

[@nibblrrr7124]

​@@leysont Not sudo per se, but in general everything in /bin, /lib, and /usr (except /usr/local) should be owned by the system package manager. Otherwise you quickly make a mess. E.g. a package installed with pip may be overwritten by apt (which may already break things); and then if you remove it with one package manager, the other one doesn't know about it and still expects it to be there. All kinds of issues. Manually installed binaries/libraries should go in ~/.local, /usr/local, or maybe /opt.

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

[@bpbleach]

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

[@laolalock909]

Have you ever patched a BIOS/EFI from the binary delivered by Lenovo website to a chip via CH341a ?

[@cr1spii]

I have bios version 2.51 on my t440p wondering if I should update to 2.52 (same one used in your video) or keep it at 2.51, dont know which would provide best chances of this hack working.

[@leansupremacy899]

What would theoretically be the best WiFi card I could possibly put in after removing the white list?

[@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

[@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.

[@alex_fernan]

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?

[@roberthorvath8223]

Is there no such solution for Thinkpad P53?

[@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 👍🏻

[@rameshgopalaswamy5740]

Great video! I want to upgrade my Lenovo Thinkcentre M92Z AIO with a WiFi card. Can this be done? This computer came with an Intel Centrino Wireless-N 2230. Recently I bought an Intel Dual Band Wireless-AC 7260 for upgrade. When I installed it, of course, I got an error about "unauthorized card" etc... Then I learnt that I need to remove the whitelist set by Lenovo. Can someone please advise? Where can I find a patch file for this? Any other tip is much appreciated. Thanks!

Do you know if there is a modified bios solution for lenovo w540 to avoid the verification of original charger wattage???

[@windowviews150]

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?

[@WolfgangsChannel]

You might miss out on some firmware improvements, microcode and security updates

[@RizkyAshary]

please review, remove whitelist on asus x450 lcp laptop, i want to use egpu with riser

[@oureuphoriant]

T540p is not compatible with the patch for T440p/W540/T540. Also note that the T540p requires a complete teardown in order to flash the BIOS. I verified that the image flashed to the BIOS matched the patched image, and that the patched image differed from the original image. Installing an Intel AX200 network card still resulted in error 1802, unauthorized network card. One of the other patches could tried...but I'm not about to completely disassemble and reassemble my laptop again just to test it.

[@stefanwichura3405]

I can help you. Send me your BIOS dump. [e-mail]

[@tylerwatt12]

Mine works. Try it again (get the v7 patch), but don't touch the patch.txt file. It worked for me. I also upgraded my bios to the latest available version beforehand. Using AX200 work fine.

Unfortunately no, since WSL runs in a virtual machine and doesn't have direct access to hardware.

can this be used to upgrade the TPM to 2.0 so i can still use my laptop when windows 11 rolls out?

[@connormccaffrey]

Hey Mate, really appreciate all your videos, personally just got my T440P this wedesday and went straight into catalina 10.15.7 but unfortunately i didnt update the BIOS before hand as i was not aware its something i should have done, currently i have working wifi with intel wifi but i ordered a DW1820A off ebay and foundout the hard way this card was not on the whitelist (i has seen this video previously but i thought the DW1820A was already whitelisted by lenovo) im wondering if im on BIOS 2.32 whats your suggestion for getting the DWA1820A whitelisted? for example should i update the bios first to 2.52 (can i do this using mac only?) and order the kit on ebay to then flash it myself? or before i do this is there potentially any chance the lenovo bios 2.55 or something else other than updating to 2.52 or staying on 2.32 and removing the whitelist would solve the issue? im not super tech savvy, but i dont have any windows instalation on this disk so i cant just boot into windows and update the BIOS that way, thats my biggest problem that im not sure how i should flash the BIOS from mac to update it to 2.52 to start.

[@WolfgangsChannel]

I tried DW1820a on my t440p and couldn't make it work. The only way to make sure the OS even boots with the card connected to the laptop, is to replace one of the built-in kexts with El Capitan version. However, that causes glitches, reboots and the system has like 25% chance of crashing on resume.

[@connormccaffrey]

@@WolfgangsChannel could be your version of the card, the version i bought was expensive and seems to be one that should work, from what i have read other users reporting if i can get the bios to accept the DW1820A i think i can get it to run just fine. but this is VERY good to know, thanks, if i recall your version of the card was the $10 on on aliexpress?

[@connormccaffrey]

@@WolfgangsChannel also another few things. sorry, if you didnt get your DW1820a to work, what card did you get to work that you did use the BIOS mod for? and have you got airdrop working on T440P? lastly have you got cardreader working on T440P on catalina? i cant seem to find confirmation from a single person who has.

[@WolfgangsChannel]

@@connormccaffrey I bought mine on eBay and it seemed to be the version that works, judging by what was written on the card. Realistically, you have two options: DW1650 or an OG Airport card from a Macbook Air and an M.2 adapter. I've documented the process here: notthebe.ee/airport.html AFAIK, this particular card might not be compatible with Catalina so do your research before buying it. I've only used Mojave on my T440p. I don't own the machine anymore, unfortunately.

[@connormccaffrey]

@@WolfgangsChannel thanks for this, good info, based on jloisels github it seems very hard not to believe DW1820a is working in catalina because a few posts basically say it is fully working. DW1830 wouldnt be a smart move, it used 3x3 configuration and putting this into a 2x2 laptop can cause problems, essentially if connecting to a 3x3 router one of the signals is gonna be much worse and will create odd issues. ive ordered a kit to mod the bios, so once its modded i will try DW1820a and if it doesnt work i will try DW1650, thanks again wolfgang!

[@VitaliiPanov-l5p]

Maybe someone has encountered this. At first I tried to read the firmware with the claws (I disconnected and connected it to the chip with an unconnected USB programmer many times), I had to unsolder the chip and flash it without the claws. then I soldered it to the motherboard. Now the laptop does not respond to the power button. I flashed it again with the old unmodified BIOS, the laptop also does not work. How to fix it?

[@WolfgangsChannel]

It’s possible that you knocked some capacitors off the board

[@VitaliiPanov-l5p]

I didn't find any broken components. I think something burned because I used the claws while the programmer was turned on in USB

[@vitaliypanov4747]

Everything is fine. It turns out that Lenovo W541 does not start without an additional USB and LAN card. Everything worked out great. Brilliant video!!!

[@BeanWibawanto]

[@fedepetit]

Would it be possible to do this for an old Lenovo G450 and G470?.

[@BenKistner]

Hey, I'm sure you're tired of people asking things like this, but do you know if this patch will work for a ThinkPad P71? I already did the BIOS dump and I am playing around with the binary file now. I just wanted to know if anyone here can confirm whether the whitelist removal patch will work with that model as well? I would just like to be able to install a WiFi 6 module and a 5G cellular module in my P71, but I obviously can't with the stupid whitelist.
