Remember to flash only `bios` region (use `--ifd -i bios -N`). `fd` and `me` are still locked. +**Note:** if you're flashing coreboot for the first time, you should have an external SPI programmer just in case. It will help you recover if you flash non-working ROM. + # SandyBridge series (X220, T420, etc.): WIP S3 Boot Scripts are unprotected on these models too (even on the most recent BIOS versions), but it's not useful, because FLOCKDN and SPI protected ranges are set by **LenovoFlashProtectPei** UEFI module. It is trivial to patch it, but it resides in protected range, so it can only be flashed externally. |
