Hi!

In Lenovo ThinkPad X240, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, to create your bios backup (dump) you need to use hardware SPI programmer only.

Also, 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/nujmxfave2

I recommend you use software AsProgrammer_1.4.1

Привет!

В Lenovo ThinkPad X240 любую модифицированную версию BIOS можно прошить только с помощью аппаратного программатора SPI, точно так же, как описано в первом сообщении этой ветки.

Таким образом, для создания резервной копии (дампа) BIOS вам необходимо использовать только аппаратный программатор SPI.

So I need something around ezp2023+?

Yes, you can use ezp2023+, but CH341A is a cheaper model. Also, you need SOIC-8 clip.

For examle: https://www.wildberries.ru/catalog/90494228/detail.aspx

Да, можно использовать ezp2023+, но CH341A — более дешевая модель. Также нужен зажим SOIC-8.

Например: https://www.wildberries.ru/catalog/90494228/detail.aspx

But i'm used CH341A for create backup Bios. So it doesn't fit?

Также я проверил ваш файл bios dump, к сожалению, он неверный. Вам нужно снова прочитать ваш bios dump из вашего bios chip, возможно, несколько раз, и сравнить в любом hex-редакторе (например, HxD), все дампы должны быть идентичны.

 

 

Если у вас возникнут проблемы с чтением дампа BIOS с чипа BIOS, попробуйте использовать другую версию программного обеспечения.

Все версии ПО для программатора Ch341A я разместил по этой ссылке: https://files.fm/u/nujmxfave2

Я рекомендую вам использовать программное обеспечение AsProgrammer_1.4.1

I'll try the math again

Again, the CH341A programmer is a good choice in your case.

I tried reading the bios dump again. This time using two programs from your archive (thanks for it). Looked through HxD, no difference with the initial one (maybe I'm blind).

Hi! Can you help me modify the BIOS on my Lenovo X240? I want to install a new Wi-Fi card, and the system gives me an "Unauthorized network card".

I understand that I need an SPI programmer. The manual in the first post says that the CH341A programmer is needed. If I buy a programmer CH341B, CH341C or CH341F - will these models be suitable? Or is it the CH341A that is needed? Thanks!

Yes, this one will be ok. Also don't forget the SOIC-8 clip. Also read this:

Hiya, do you still make BIOSes for the x240?

 

If so, when I give it to someone to do it for me, what do I tell them I need for this to be done?

This is mainly to upgrade to WiFi 6, but might as well also get the hidden options.

Hi, with the original BIOS (linked below, chip is a Winbond W25Q128FV) I'm getting no boot most of the time (power comes on, fan may spin, sits there for a minute or so then turns off), sometimes 2 series of 5 beeps (which appear to be TPM-related?), and very rarely a successful boot. I've tried a number of BIOS bins - some result in no powerup at all, others in a constant powercycle (which makes reflashing the BIOS a hassle, I have to desolder now, as I can't draw 3.3V from the board itself when it's cycling constantly and the CH341A can't source enough to drive the chip on its own). I tried me_cleaner on the original BIOS dump, but that also resulted in no powerup. I was unable to update/reflash the BIOS from within Windows, the Phoenix WinFlash tool failed out with Error 216 & code 1501, unable to read the flash chip. Is there something else I can try? If a mod is possible as well (although not my main objective), I would appreciate it as well!

Hi!

In your case, your laptop have some hardware issue (your problem doesn't relayted with bios file).

I recommend you contact a repair center.
