For the t440p this is kinda a part 1 video. I install tianocore and coreboot on a x220 and t440p thinkpads, Although the t440p is still partly dissassembled.
Thanks to [ Ссылка ] for his tianocore t440p coreboot tutorial. His configuration posted works fine, and was the test configuration for the flashing back a working rom.
I would use ME Cleaner as well, though, from the normal branch.
For those more interested Mr. Chromebox is very knowledgeable about tianocore and coreboot. He manages a series of precompiled coreboot roms for chromebooks, and often answers questions on Reddit.
