bad rom (or user error), machine won't boot

-

- In this scenario, you compiled a ROM that had an incorrect configuration, or there is an actual bug preventing your machine from - booting. Or, maybe, you set BUC.TS to 0 and shut down after first flash while Lenovo BIOS was running. In any case, your machine is bricked and will not boot at all. -

-

- "Unbricking" means flashing a known-good (working) ROM. The problem: you can't boot the machine, 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. Highlighted is the SPI flash chip:
- -

-

- Now wire up the BBB and the Pomona with your PSU.
- Refer to bbb_setup.html for how to setup - the BBB for flashing.
- Note, the guide mentions a 3.3v DC PSU but you don't need this on the X60: - if you don't have or don't want to use an external PSU, then make - sure not to connect the red/black 3.3v leads mentioned in the guide; - instead, connect the AC adapter (the one that normally charges your - battery) so that the board has power (but don't boot it up) -
