Manually Flashing ROMs
DANGER
Flashing your own firmware has the potential to brick your device. Do not do this unless you are sure you know what you are doing/have a way to recover from a bad flash. Some level of knowledge with using the Linux command line is required.
- Have your firmware rom. We will assume you already have the file you want to flash for this guide.
- Download flashrom, then give it execute permission.
- For most distributions:
cd; curl -LO https://files.tree123.org/utils/x86_64/gnu/flashrom; chmod +x flashrom - For musl (Alpine Linux):
cd; curl -LO https://files.tree123.org/utils/x86_64/musl/flashrom; chmod +x flashrom
- For most distributions:
- Flash your custom ROM
- Backup your current rom, just in case things go wrong:
./flashrom -p internal -r current.rom - Note: Intel Chromebooks should be flashed with
--ifd -i biosex:sudo ./flashrom -p internal --ifd -i bios -w coreboot.rom - Flash your custom firmware:
sudo ./flashrom -p internal -w firmware.rom
- Backup your current rom, just in case things go wrong:
- Reboot
