[REQUEST] ThinkPad T14 Gen 1 (20S1) - Custom Boot Logo Modification

Hello everyone!
I hope this is the right section for this request. I'm looking for help to modify the boot logo on my ThinkPad T14 Gen 1.
System Information:

• Model: Lenovo ThinkPad T14 Gen 1
• Machine Type: 20S1S4E600 (Intel i7 variant)
• Current BIOS: N2XET42W (1.33) - Latest version
• BIOS File: n2xuj25w.exe (12.98 MB) - Downloaded from Lenovo support

What I'm trying to achieve:

Replace the default "LENOVO" boot logo with a custom image during POST.
🔧 What I've tried:

• lenovo-logo-changer - Returns "Your device is not supported!"
• LogoDiy - Found source code only, no compiled version available
• Manual research - Found this community as the best option for expert help

Files I have ready:

• Original BIOS: n2xuj25w.exe (verified from Lenovo support)
• Custom image: 1920x1080 BMP format, 9.72 KB (optimized for BIOS compatibility)
• Current BIOS backup: Can provide if needed using recommended tools

What I'm looking for:

I would greatly appreciate if someone experienced with Lenovo BIOS modifications could:

• Modify my BIOS file to include the custom logo
• Provide guidance on safe flashing procedures
• Share any T14-specific considerations I should know about

My understanding of the risks:

• BIOS modification can brick the device if done incorrectly
• I have recovery options available (Fn+R method for ThinkPads)
• I'm willing to provide any additional information needed
• This is for personal use only, I understand warranty implications

Technical details:

• OS: Dual boot Arch Linux + Windows 10
• Experience level: Comfortable with technical procedures, but new to BIOS modification
• Backup capability: Yes, can create full system backup before proceeding

I really appreciate any help, guidance, or even just pointing me in the right direction. This community seems to be the gold standard for BIOS modifications, and I'm grateful for your expertise.

Thank you in advance!

P.S.: If this request belongs in a different section or if I should provide additional information, please let me know. I'm happy to follow any community guidelines.

OK, I understand the risks and I will definitely create a BIOS backup before proceeding with any modifications.

However, I'm not entirely sure how to proceed with the backup process. Is there perhaps a guide on how to do this without external software? And most importantly, something that's compatible with my specific laptop model?

I want to make sure I do this correctly to avoid any complications with the ThinkPad T14 Gen 1 (20S1S4E600).

Like, I know ok, I do the backup but later what? Idk how to put the new image in the bios with no brick frv my laptop :/

I see a another foro for this but I guess know is unviable and idk what, maybe the page is down :c

Any guidance would be greatly appreciated. Thanks!
