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:\ + + +Push the keyboard forward (carefully):\ + + +Lift the keyboard up and disconnect it from the board:\ + + +Grab the right-hand side of the chassis and force it off (gently) and +pry up the rest of the chassis:\ + + +You should now have this:\ + + +Disconnect the wifi antenna cables, the modem cable and the speaker:\ + + +Unroute the cables along their path, carefully lifting the tape that +holds them in place. Then, disconnect the modem cable (other end) and +power connection and unroute all the cables so that they dangle by the +monitor hinge on the right-hand side:\ + + +Disconnect the monitor from the motherboard, and unroute the grey +antenna cable, carefully lifting the tape that holds it into place:\ + + +Carefully lift the remaining tape and unroute the left antenna cable so +that it is loose:\ + + +Remove the screw that is highlighted (do NOT remove the other one; it +holds part of the heatsink (other side) into place):\ + + +Remove those screws:\ + + +Carefully remove the plate, like so:\ + + +Remove the SATA connector:\ + + +Now remove the motherboard (gently) and cast the lcd/chassis aside:\ + + +Lift back that tape and hold it with something.
