Upcycle HP Chromebooks with MrChromebox bios
YMMV but here is the generic outline Basic outline is here: https://docs.mrchromebox.tech/docs/getting-started.html#replacing-chromeos-via-full-rom-firmware Some notes: ------------------------ 1. Verify your device has UEFI Full ROM support 2. Put your device in Developer Mode 3. Disable the device's hardware firmware write protection (via screw, jumper, battery, or CCD) 3a. On the steps where you need to disable the firmware write protect mechanism, on the HP G5 EE device break the clamshell open. Upon getting the clamshell seperated see the pic below for the write protect screw and remove the screw.4. Run the Firmware Utility Script 4a. And do note that in the script command below, it's `-LO` (L capital O), not L zero. To download and run this script under ChromeOS terminal (ctrl + alt + t) and type shell. Or in Linux, from a terminal/shell type:
cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.shIf you encounter certificate related errors when downloading the script from ChromeOS, then add -k to the curl command and script command to bypass SSL certificate checking as so: cd; curl -LOk mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh and press [ENTER]. 5. Flash the UEFI Full ROM Firmware 5a. 2yyn as of 20250212 6. Reboot 7. Boot and install your new OS
