## "fixflags" images These "fixflags" images are used to set the "crossystem" flags on your machine properly, to enable Legacy Booting for GalliumOS. These images are derived from the official ChromeOS Recovery Images, but the Recovery code has been replaced with a simple script that runs: sudo crossystem dev_boot_legacy=1 (Note that if you are still able to boot ChromeOS (dual-booting), you can just run that command from a ChromeOS shell, no fixflags image required) Fixflags images are used exactly like Recovery Images: 1. Select the image appropriate for your hardware ID. If there is no image for your device, let us know on IRC and we'll make one for you: https://galliumos.org/irc 2. Write the image to USB drive or SD card ** This is the most error-prone step! See troubleshooting steps ** at https://wiki.galliumos.org/Installing/Creating_Bootable_USB - Recommendation for most users: Use Etcher (extract the .zip file, and rename the resulting .bin to .iso, first) - If you're comfortable with "dd", use that instead (extract the .zip file first) - If you use the ChromeOS Recovery Tool to write the image, you do not need to unzip the image first 3. Press Esc+Refresh(F3)+Power to initiate ChromeOS Recovery 4. Insert your freshly-written USB or SD media You will see a message that the ChromeOS image is unverified, but since you're already in Developer Mode, booting will continue. You'll see a message that ChromeOS is being Recovered. In fact, only your crossystem flags will be set, so this step will finish quickly (within a few seconds, whereas the full recovery takes a few minutes). After the crossystem flags are reset, your chromebook should reboot properly, but the system hardware clock might be wrong, which will prevent Wi-Fi access. To fix your system hardware clock, see: https://redd.it/4rt4ez To prevent the crossystem flag reset in the future, you can set GBB flags using the firmware flashing script from MrChromebox. Full docs at https://wiki.galliumos.org/Firmware and https://mrchromebox.tech/. Note that _some_ of these fixflags images will also set GBB flags. Unless that's your intention (and you are otherwise prepared for it), make sure to check the filename carefully, and download the image tagged "fixflags" only, not "fixflags+gbb=0x489" or similar.
