ThinkPad X60: Recovery guide

This section documents how to recover from a bad flash that prevents your ThinkPad X60 from booting.

Back to previous index

+ +

+ Types of brick: +
- Brick type 1: bucts not reset
- Brick type 2: bad rom (or user error), system won't boot
+

+ +

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 X60 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 system that still has Lenovo BIOS running, + using those instructions: http://www.coreboot.org/Board:lenovo/x60/Installation. +

+ +

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

+ In this scenario, you compiled a ROM that had an incorrect configuration, or there is an actual bug preventing your system 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 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. 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 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) +
+ Correlate the following with the BBB guide linked above: +

+POMONA 5250:
+===  golden finger and wifi switch ====
+ 18              -       - 1
+ 22              -       - NC                    ---------- audio jacks are on this end
+ NC              -       - 21
+ 3.3V (PSU)      -       - 17 - this is pin 1 on the flash chip
+===  CPU fan ===
+This is how you will connect. Numbers refer to pin numbers on the BBB, on the plugs near the DC jack.
+

+ +

+ Connecting the BBB and pomona (in this image, an external 3.3v DC PSU was used):
+ +

+ +

+ Flashrom binaries for ARM (tested on a BBB) are distributed in libreboot_util. Alternatively, + libreboot also distributes flashrom source code which can be built. +

+ +

+ SSH'd into the BBB:
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w yourrom.rom +

+ It should be Verifying flash... VERIFIED at the end. If flashrom complains about multiple flash chip + definitions detected, then choose one of them following the instructions in the output. +

+ +

+ Remove the programmer and put it away somewhere. Put back the tape and press firmly over it:
+ +

+ Your empty chassis:
+ +

+ Put the motherboard back in:
+ +

+ Reconnect SATA:
+ +

+ Put the plate back and re-insert those screws:
+ +

+ Re-route that antenna cable around the fan and apply the tape:
+ +

+ Route the cable here and then (not shown, due to error on my part) reconnect the monitor cable to the motherboard + and re-insert the screws:
+ +

+ Re-insert that screw:
+ +

+ Route the black antenna cable like so:
+ +

+ Tuck it in neatly like so:
+ +

+ Route the modem cable like so:
+ +

+ Connect modem cable to board and tuck it in neatly like so:
+ +

+ Route the power connection and connect it to the board like so:
+ +

+ Route the antenna and modem cables neatly like so:
+ +

+ Connect the wifi antenna cables. At the start of the tutorial, this system had an Intel wifi chip. Here you see I've replaced it with an + Atheros AR5B95 (supports 802.11n and can be used without blobs):
+ +

+ Connect the modem cable:
+ +

+ Connect the speaker:
+ +

+ You should now have this:
+ +

+ Re-connect the upper chassis:
+ +

+ Re-connect the keyboard:
+ +

+ Re-insert the screws that you removed earlier:
+ +

+ Power on!
