title: ThinkPad X230/X230T external flashing
|
|
x-toc-enable: true
|
|
...
|
|
|
|
**Minifree now sells the Libreboot T480, instead of the Libreboot X230. See:
|
|
<https://minifree.org/product/libreboot-t480/>**
|
|
|
|
**NOTE: Libreboot standardises on [flashprog](https://flashprog.org/wiki/Flashprog)
|
|
now, as of 27 January 2024, which is a fork of flashrom.
|
|
The reason why was explained, in
|
|
the [Libreboot 20240225 release](../../news/libreboot20240225.md#flashprog-now-used-instead-of-flashrom)**
|
|
|
|
**[PLEASE READ THESE INSTRUCTIONS BEFORE INSTALLING](../../news/safety.md),
|
|
OR YOU MIGHT BRICK YOUR MACHINE: [SAFETY PRECAUTIONS](../../news/safety.md)**
|
|
|
|
NOTE: Internal flashing (from vendor firmware) to Libreboot is possible, on
|
|
this board, but the steps are a bit more complex than using an external flasher.
|
|
See: [internal ivybridge flashing](ivy_internal.md)
|
|
|
|
Read the [Ivybridge/Haswell common guide](ivy_has_common.md) if you want more information.
|
|
All of the following instructions assume that you've cloned lbmk and are operating from the
|
|
root of that project. To do so, run
|
|
|
|
git clone https://codeberg.org/libreboot/lbmk
|
|
cd lbmk
|
|
|
|
You can now follow the rest of the instructions.
|
|
|
|
Preparing a release Rom
|
|
-----------------------
|
|
|
|
**Please follow this prior to flashing, or you may brick your machine.**
|
|
|
|
Please [inject vendor files](ivy_has_common.md) prior to flashing. You can also
|
|
use this guide to change the built-in MAC address for your Intel Gigabit
|
|
Ethernet device; doing so is advisable, because otherwise you will have a
|
|
default, generic MAC address.
|
|
|
|
Splitting The Rom
|
|
-----------------
|
|
|
|
You can use `dd` to easily split your rom into the two separate portions for
|
|
external flashing.
|
|
|
|
dd if=libreboot.rom of=top.rom bs=1M skip=8
|
|
dd if=libreboot.rom of=bottom.rom bs=1M count=8
|
|
|
|
Flash the top chip with top.rom, and tho bottom chip with bottom.rom.
|
|
Don't worry about knowing which chip is which on a standard setup; flashprog will let you know if the
|
|
image size is incorrect for the chip you're flashing.
|
|
|
|
Disassembly
|
|
-----------
|
|
|
|
Start by removing the battery.
|
|
Remove every screw from the bottom of the machine marked with a keyboard/touchpad indicator.
|
|
|
|
Pry up the keyboard and separate it from the palmrest.
|
|
|
|
|
|
Unplug the ribbon cable from the palmrest and pry it off as well.
|
|
|
|
|
|
Pull up the protective cover to reveal the two soic chips for flashing.
