IVprep VS brave-browser-hardening

You can downgrade the X230 BIOS to version 2.60 from Windows using IVPrep.

If your Bios is above the vulnerable version, you need IVprep, this only works on Windows10 (or above), maybe using Freedos too, but no guide online I could find.

Installed thinkpad-ec patch and coreboot (with skulls/ivyrain) on my x230t but I reverted back to the stock keyboard so I don't want thinkpad-ec anymore. I tried to flash back the stock bios to get rid of it with [this]( IVprep/X230t.FL1 at master · n4ru/IVprep · GitHub ) FL1 file converted to a ROM with dd, but flashrom says that my chip size doesn't match and is 12MB. I've looked online for a while and extracted an FL1 file from a Lenovo BIOS update but none I can find are 12MB. Does anyone have any links to one?

I think that just pushes a UEFI capsule too, at least that is what this suggests.

And IVprep https://github.com/n4ru/IVprep/

if you want to install https://github.com/lynxis/thinkpad-ec so that you can use a *20 keyboard and a *20 battery on *30 or if you want to prepare to that with https://github.com/n4ru/IVprep/ or if you want to install https://github.com/n4ru/1vyrain after that to gain more options in BIOS and/or be able to use non-Lenovo-approved Wi-Fi card - you don't need a hardware flasher; you don't need it for either of these 3 projects; all 3 use normal software flashing; I also understand all 3 are fairly safe to use; lots of people have used them and I haven't seen much complains

Once you run IVprep you should be on BIOS version 2.64 on the T430.

Lots of hardening is not possible on Brave, see the Brave Hardening Guide. It disguises as Chrome though, even though not hiding your main OS.

I switched to Brave, but that Browser still has major disadvantages over Firefox. Downloading Addons from Github (handling updates manually aarg) to avoid the Chrome Store, and lots of security hardening not possible made me switch back.

There are pages like this https://gitlab.com/CHEF-KOCH/brave-browser-hardening but I think it's not that needed since Chromium makes everything easy to do and understand since flags and the descriptions are explained well enough for you to understand them if you want features or not.

You can use this guide to harden brave by yourself.
