"Battery whitelist" does not exist...the control of the battery is carried out by the EC

[Monorail0389]

Hello people.

I own a Lenovo B590 and I want to remove the battery check from EC and the wifi whitelist.
These are the specifics:

Code:

Product: LENOVO B590
Model Name: 62742BG
BIOS: H1ET69WW (1.12)
EC version: H1EC31WW (1.11)

I performed a BIOS backup using Universal BIOS Backup Toolkit 2.0 and this is the generated file: https://file.io/UuEIYpnvmQyv
I'm not sure that's enough to provide me a patch, in case let me know what I should do.

Thanks in advance

If you are already using my patcher, why not just patch it yourself? :-)

Just download my repository at https://github.com/leecher1337/thinkpad-Lx30-ec and execute it in the fwpat directory.

Thanks for replying, i've been using the Bootable ISO for EC hotpatching, would much appreciate if you can upload the patched bios, or if there is a step by step guide to patch and then reflash would be helpful. Cheers ?
