Or, maybe, you set BUC.TS to 0 and shut down after first flash +while Lenovo BIOS was running. In any case, your system is bricked and +will not boot at all. + +"Unbricking" means flashing a known-good (working) ROM. The problem: +you can't boot the system, making this difficult. In this situation, +external hardware (see hardware requirements above) is needed which can +flash the SPI chip (where libreboot resides). + + + +Remove those screws:\ + + +Remove the HDD:\ + + +Push keyboard forward to loosen it:\ + + +Lift:\ + + +Remove those:\ + + + + +Also remove that (marked) and unroute the antenna cables:\ + + +For some X60T laptops, you have to unroute those too:\ + + +Remove the LCD extend board screws.
