Brick type 1: bucts not reset.

-

- You still have Lenovo BIOS, or you had libreboot running and you flashed another ROM; and you had bucts 1 set and - the ROM wasn't dd'd.* or if Lenovo BIOS was present and libreboot wasn't flashed.

- - In this case, unbricking is easy: reset BUC.TS to 0 by removing that yellow cmos coin (it's a battery) and putting it back after a minute or two:
-

- - *Those dd commands should be applied to all newly compiled T60 ROM images (the ROM images in libreboot binary archives already have this applied!):
- dd if=coreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x10000] count=64k
- dd if=coreboot.rom bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k | hexdump
- dd if=top64k.bin of=coreboot.rom bs=1 seek=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k conv=notrunc
- (doing this makes the ROM suitable for use when flashing a machine that still has Lenovo BIOS running, - using those instructions: http://www.coreboot.org/Board:lenovo/x60/Installation. - (it says x60, but instructions for t60 are identical) -

- -

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 and remove the HDD:
- -

- -

- Lift off the palm rest:
- -

- -

- Lift up the keyboard, pull it back a bit, flip it over like that and then disconnect it from the board:
- -

- -

- Gently wedge both sides loose:
- -

- -

- Remove that cable from the position:
- -

- -

- Now remove that bezel. Remove wifi, nvram battery and speaker connector (also remove 56k modem, on the left of wifi):

- -

- Remove those screws:
- -

- -

- Disconnect the power jack:
- -

- -

- Remove nvram battery:

- Disconnect cable (for 56k modem) and disconnect the other cable:

- Disconnect speaker cable:

- Disconnect the other end of the 56k modem cable:

- -

- Make sure you removed it:

- Disconnect LCD cable from board:

- -

- Remove those screws then remove the LCD assembly:

- -

- Once again, make sure you removed those:
- -

- -

- Remove the shielding containing the motherboard, then flip it over. Remove these screws, placing them on a steady - surface in the same layout as they were in before you removed them. Also, you should mark each screw hole after removing the - screw (a permanent marker pen will do), this is so that you have a point of reference when re-assembling the machine:
- - -

- -

- 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 T60: - 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)

This guide will show you how to recover from a bad flash that prevents your ThinkPad T60 from booting.
