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's (the ROM's 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. +

+ +

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:
+ +

+

+ At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):
+ http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts.
+ Correlating with the following information, I was able to wire up my pirate correctly:
+ http://flashrom.org/Bus_Pirate#Connections
+ And by following that advice:
+ http://www.coreboot.org/Board:lenovo/x60/Installation#Howto.
+ Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.
+ Note: and then, for power it says (on that coreboot.org page) to connect the power jack to the board and connect the + AC adapter (without powering on the board).
+ Note: I ignored that advice, and wired up all 8 pins. And it worked.
+ + Here is the pinout (correlate it with your programmer's documentation):
+ +

+ +

+ My programmer (bus pirate):
+
+ My clip (pomona 5250):
+
+ Connecting the pomona:
+
+ Connecting the USB cable from programmer to 2nd(working/non-bricked) computer, my T60:
+
+ Now I install flashrom on the T60 (running Trisquel GNU/Linux) and do this:
+ flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/x60/libreboot_usqwerty.rom
+ Note: there are also other ROM images for X60
+ Note: this is using buspirate as the programmer, so it is flashing the X60, not the T60!
+ Here's my terminal window on the T60:
+
+ So, you should see the following:
+ -- +

+
+flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian
+flashrom is free software, get the source code at http://www.flashrom.org
+
+Calibrating delay loop... delay loop is unreliable, trying to continue OK.
+Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi.
+Reading old flash chip contents... done.
+Erasing and writing flash chip... Erase/write done.
+Verifying flash... VERIFIED. 
+
+

+ --
+ At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means + that you can put your X60 back together. So let's do that now. +

+

+ 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 machine 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!
