Hi!

Ok. Your unlocked bios done. Check PM.

Thanks Klem!
The patched BIOS worked great. Wife's laptop is back on WiFi 6 in... spite of Lenovo. Best $10 I've spent in a long time. Appreciate what you do!!

To anyone trying to boot their laptops into DOS, you must change UEFI to Legacy mode in the bios. Highlight UEFI and hit enter to see the "Legacy" option. Otherwise, your USB thumb drive will not show up as a boot option. Be sure to change it back when you're done flashing. It had been a long time since I'd booted into DOS, so it took me a while to figure this out. 

 

Also, this was not my computer, so I didn't know about the tiny button next to the power button on the G500s that easily gets you to the BIOS and boot options from the OFF-state. Hope this info helps others.

Bonjour, 

 

Pouvez-vous m'aider avec le déverrouillage du BIOS Lenovo G500, je veux juste installer une meilleure carte Wi-Fi mais j'ai reçu une erreur (une carte réseau sans fil non autorisée est branchée. Éteignez-la et retirez-la).

Ma version : 78CN25WW v2.03

Merci de votre aide

Hello! Could you help me remove the whitelist from the network card and unlock the BIOS of my laptop? If it's only possible to perform one procedure, I would really appreciate it if you could just remove the whitelist! I bought a card without knowing that Lenovo blocks the network card.

It’s a Lenovo G400S.

 

BIOS VERSION: 7BCN38WW(2.04)

CE VERSION: 7BEC38WW(2.04)
