I already have the bios uploaded by killer and resigned by myself, is it any different from what you have uploaded?
Could you tell us a bit more about it, if it is in fact different from the killer's one, apart from resigning?
The only thing that was left unresolved for me was the ability to replace the BIOS bootup image by myself, everything else I managed to do by myself, but not replacing bootup image by my own one, despite meeting all the requirements for it.
Do you know how could I replace the image that the PC boots up with with at the bios level my own custom one?
Hi Olokos,
I think that there isn't much differences between these, but I want to learn anything new from all friends and share the knowledgments of mine with them !
I haven't Lenovo laptop and can't do tests, but I would try to help You to make this goal.
If do You want to talk about that I'll be very happy, as I can ask to an expert own tests and goals.
I would ask about signing form You used to ...

So We can help all others users to self make own bioses

P.S. I have done many bioses modified boot logo with other manufacturers laptops in the past, but we can learn everyday something new.

I realised why I couldn't change the bootlogo.
Well, I did change it all the time correctly.
After flashing modded bios by default "fullscreen logo" or something like this gets disabled somewhere within UEFI settings.
Keep in mind to reenable fullscreen logo if you wish to have it after flashing the modded bios.

hello. I have a lenovo t520 laptop, bios version 1.49.The Bios type is Phoenix EFI, you can help modify my bios. I need the Advanced item, as well as so that I can install the intel 7260HMW wifi module, removing the whitelist check.

Unfortunately all the links for a modded BIOS for the T520 are gone.
Does anyone have a working link?
Thank you very much in advance

I can confirm that the file provided by @killer23d is legit, works great and once recompiled as @tazeat suggested the beeps are also gone!
@Marcin I'm using AX200 with BT 5.1 or 5.2 and no issues whatsoever, actually any issues with BT/WiFi I've had before are now gone.
@justwantsomerealwifi All you really need to do is read through this thread, at least several last pages, it's all there, really.
@jake120691 If you're a newbie and this laptop is valuable for you then just buy a legimate battery. Even if there's a way to bypass this, then in case of a battery failure you're risking your laptop going up in flames and taking the surrounding area around it also in flames. Have you seen vapes exploding? 99% of cases they were using el cheapo batteries and trying to pull too much power from them.
Not saying that will happen with a laptop 100% of the times, but I wouldn't risk it anyway, better to spend even those 100$ on the biggest cells original battery than risk your laptop, life and whatever is around it, especially since you're a newbie.
=======================================================================================
Here's my question now:
I've tried to replace the BIOS boot logo, I did abide to all the requirements of not only size, but also resolution, filename and I tried BMP,PNG formats, but each time I tried to do it via the flashing lenovo software provided by killer it did proceed just fine, but the bios boot image still remains black.
Any ideas how to actually replace the BIOS boot logo? That'd be the icing on the cake on my laptop

I don't recommend using the BIOS file provided in the link. After using it, my T520 became dead.
