Hi Klem, I know that there is a 5 beeps problem due to the changed file size of modded BIOS. May I know if the guide below is a correct way to create a digital RSA signature? What I know the procedure of removing whitelist: Dump the BIOS from T440p => remove whitelist => sign the RSA again to the modded BIOS=> flash the modded BIOS to T440p=> Enjoy Quote Link to comment Share on other sites More sharing options...

dimar Posted September 23, 2021 Share Posted September 23, 2021 Hi, could you please remove the whitelist so I can install any PCIe wireless card? This ThinkPad T540p has SPI1 and SPI2 chips. I copied both of them just in case. https://drive.google.com/drive/folders/1VfQH5jiqxneLHkfHpA9F8cWptuXzTNIj?usp=sharing Thanks! Quote Link to comment Share on other sites More sharing options...

Catas6 Posted October 3, 2021 Share Posted October 3, 2021 Is it possible to have this work on a W540 by any chance? Quote Link to comment Share on other sites More sharing options...

As first step, you need to read your bios chip using hardware SPI programmer (read the first page of this thread) . 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/33xntmcth I recommend you use software AsProgrammer_1.4.1 Quote Link to comment Share on other sites More sharing options...
Godzzi Posted October 4, 2021 Share Posted October 4, 2021 hi all! so I have a T440s with the latest locked bios which disabled the ability to downgrade. My intention was to write 2.36 which has no whitelist, allowing all wifi cards. So the "windows" way was not possible, and decided to buy a ch341a + the soic8. so.....I read the bios and saved it and wrote a new one. the button power flashes 3 times and that's it....no power. Flashed by backup and does the same thing. any ideas? Quote Link to comment Share on other sites More sharing options...

Your backup bios file may have been read incorrectly, with errors, and therefore it may also be corrupted. 2. Write procedure proceeded with some errors.

Godzzi Posted October 4, 2021 Share Posted October 4, 2021 thanks! trying to find more and more dumps of T440s and trying them all. Just started to use AsProgrammer as you recommend because this one seems to properly know the IC W25Q128FV Quote Link to comment Share on other sites More sharing options...

Godzzi Posted October 4, 2021 Share Posted October 4, 2021 so I was able to write a dump from the internet but I think something is not working properly. I get a really slow boot up time before the bios screen (remains just black) + my left USB stopped working. I wonder if I broke the USB while I was thinkering or it's a bad BIOS. Here's my 1st dump save which is mine. Can someone please remove the wifi whitelist? https://drive.google.com/drive/folders/19OKOt9pVCVGMvjYj_5_V4CU3tI-KW6As?usp=sharing Quote Link to comment Share on other sites More sharing options...

FUBob Posted October 22, 2021 Share Posted October 22, 2021 (edited) Quick question - The first post links to some SPI readers/programmers and all seem to be 5V logic. Has anybody had the BIOS chip in a T440s pop because the chip is 3V3, but working on 5V? Please advise, FUBob Edited October 22, 2021 by FUBob punctuation fix, no biggie Quote Link to comment Share on other sites More sharing options...
