so yeah. hda_sdo thing has been known for years, but i had someone on osboot irc earlier, with old osboot setup with locked ifd regions, i helped him unlock without spi flasher, using the hda_sdo trick
flashing from lenovobios is trickier, because lenovo uses pr0 regs to write protect the bios region
see links above. should work. all you need is....
tweezers. metal ones
enjoy!
