 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.
 :::
 
-1. Have your firmware rom. We will assume you already have the file you want to flash for this guide.
-2. Download flashrom, then give it execute permission.
+1. The steps below assume you are flashing an image named `coreboot.rom`; substitute it as necessary.
+
+2. Download flashrom, cbfstool, and gbb utility, decompress, and ensure they are executable:
    - 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`
+   - `wget https://mrchromebox.tech/files/util/cbfstool.tar.gz && tar -zxf cbfstool.tar.gz && chmod +x cbfstool`
+   - `wget https://mrchromebox.tech/files/util/gbb_utility.tar.gz && tar -zxf gbb_utility.tar.gz && chmod +x gbb_utility`
+
 3. 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 bios` ex: `sudo ./flashrom -p internal --ifd -i bios -w coreboot.rom`
-   - Flash your custom firmware: `sudo ./flashrom -p internal -w firmware.rom`
+   - Backup your current firmware (just in case things go wrong):
+     `sudo ./flashrom -p internal -r backup.rom`
+   - Extract your VPD from your backup:
+     `./cbfstool backup.rom read -r RO_VPD -f vpd.bin`
+   - Inject the VPD into your custom ROM:
+         `./cbfstool coreboot.rom write -r RO_VPD -f vpd.bin`
+   - Extract your HWID and inject it into the custom ROM (if it exists)
+       - if your current firmware came from the firmware utility script run
+         - `./cbfstool backup.rom extract -n hwid -f hwid.txt`
+       - if it is stock firmware then run
+         - `./gbb_utility backup.rom --get --hwid > hwid.txt`
+       - `./cbfstool coreboot.rom add -n hwid -f hwid.txt`
+   - Flash your custom firmware:
+       - AMD devices: `sudo ./flashrom -p internal -w coreboot.rom`
+       - Intel devices: `sudo ./flashrom -p internal --ifd -i bios -w coreboot.rom`
 4. Reboot
-   - Assuming it said `success` on all checks, reboot.
+   - Assuming flashrom shows `success` at the end of the process, reboot.
 
 ::: danger
 Do not reboot if any of the checks failed.
