Battery is from vhbw and currently has 43% charge, but T530 refuses to charge it since it's not genuine.
1) Bios is currently 2.67, do I need to upgrade it to a more recent stock version before the procedure?
2) Is the procedure safe or do I risk to brick the notebook if something goes wrong?
The way I understand the instructions in README file you linked is they suggest us to upgrade to the latest official BIOS version available which isn't locked. I'm planning to go through this process myself with X230 but haven't done so yet.. My reason to go through it will be different; it will be to use a classic keyboard. But regardless of that It would actually be great if you could post what you do step-by-step here so that I can follow
The one bit from README that looks relevant is this
To me that's the final check to make after upgrading BIOS to latest non-locked version and writing the image generated by thinkpad-ec software to a USB stickFor safety, ensure that the EC version you are running is the same as the EC version used by the patched image you build. The version used to build the patch is shown at the end of the build process and during the pre-flash warning message

As far as I understand, it does not depend on the bios, it depends on the embedded controller (EC).
Anyone here with first-hand experience that can answer my questions?
