I have a Lenovo ThinkPad E540 and I’m trying to replace the stock Intel 7260HMW BN Wi-Fi card with an Atheros AR5B22 (Half Mini PCIe). However, I’m getting the 1820 unauthorized network card error when I boot with the new card.

 

Could you help me with a modified BIOS that removes the whitelist? I'd also love to have the advanced BIOS menus unlocked, if possible.

 

I don’t currently have a hardware programmer, but I’m willing to get one (like a CH341A with SOIC8 clip) if needed. Please let me know what method you recommend and how I can provide a BIOS dump if it’s required.

 

Thanks so much for your help!

Hi!

In your laptop model, 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 bios backup (dump) you need to use hardware SPI programmer.

When you will received your hardware SPI programmer, then you can read and send me your file bios dump to unlock.

Muchas gracias de antemano y un saludo.

 

 

Hi!
You have posted your problem in the wrong place. This thread is only for requests to unlock Wi-Fi whitelist and to unlock hidden advanced settings in BIOS setup menu!
But you can create another thread on the forum with your laptop problem.

Hello, Klem,
I would need to whitelist my x250 device so I can use a new WWAN module I bought.
Tried to do it by myself with UEFIPatch and HxD but failed miserably...

Your assistance would be appreciated!

Hi Klem, hoping you're able to help me out as you have so many!

I have a P650SE (badged by Metabox in Australia but a Clevo at heart), and would love to get NVMe boot support on it - it's a great laptop, still does 90% of what I need, and a bit of a speed boost from a new drive would be great! I've tried following the guide at https://winraid.level1techs.com/t/howto-get-full-nvme-support-for-all-systems-with-an-ami-uefi-bios/30901 but hit a wall with the downloads for the NVMe files (they seem to be broken... hopefully not just my incompetence!). Plus, I'm not ENTIRELY confident with modding a BIOS file.

I'm not entirely sure what info you'd need - I got a copy of the latest BIOS update for my model (not my individual system) from the distributor, which I have uploaded to https://www.sendspace.com/file/xb89ha. If you're able to help, please let me know what more you'd need, and thank you for your contributions - whether you have the time to help me or not!

Hi!

Each bios mod prepared individually and based on your personal file backup of bios.

You can post here your file bios backup, or upload it into any fileserver and post the link. To create your bios backup use attached utility. Extract attached archive directly on the Desktop and run utility as Administrator (right click mouse, choice "Run as Administrator"). Utility will create archive "results" directly on the Desktop. Post here this archive "results", or upload it into any fileserver and send me the link.

Hi Mod,

 

Sorry if it takes awhile to get back to you.  I have to order the CH341A programmer and learn how to use it.

I'm hoping I've done this right. I've exported my BIOS file (autodetected as three different possible models, so I chose the first one)

Hello, Klem!

Can you help me maybe? I could pay you something. It’s the same like the others in this topic. I would like to know the bios whitelist (particularly for wifi-card) so that I can buy a wifi-card that’s compatible. Or delete the white-list so I can install any wifi-card. I really don’t know how this works though, so if you would, please just ask me the information you need to be provided with.

 

And I would like to thank you so much in advance!
