--- title: ThinkPad X230/X230T external flashing x-toc-enable: true ... Read the [Ivybridge/Haswell common guide](/docs/install/ivy_has_common.html) 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://notabug.org/libreboot/lbmk cd lbmk You can now follow the rest of the instructions. Preparing a release Rom ----------------------- You must patch the release rom with the necessary blobs *and then* flash it to your board. Lbmk includes a script that will automatically inject the necessary blobs into a rom file. The script can determine the board automatically if you have not changed the name, but you can also manually set the board name with the `-b` flag. In order to inject the necessary blobs into a rom image, run the script from the root of lbmk and point to the rom image. For example: ./blobutil inject -r x230_libreboot.rom -b x230_12mb Optionally, you can use this script to modify the mac address of the rom with the `-m` flag. For example: ./blobutil inject -r x230_libreboot.rom -b x230_12mb -m 00:f6:f0:40:71:fd NOTE: this makes use of `nvmutil`, which you can read more about in the [nvmutil documentation](nvmutil.md). 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; flashrom 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. ![](https://av.libreboot.org/board/x230/palmrest.jpg) Unplug the ribbon cable from the palmrest and pry it off as well. ![](https://av.libreboot.org/board/x230/palmrest_cable.jpg) Pull up the protective cover to reveal the two soic chips for flashing. ![](https://av.libreboot.org/board/x230/chipLocation.jpg)
