Crimson Moon:full_moon:

This project is designed to fix/improve the chromeos flex experience for the more advanced users

I am not responsible for any damage or harm that may occur to your device as a result of following this tutorial. Proceed at your own risk.

Requirements

Patching (enable dev mode)

• Live linux usb (if you can acces CTRL + ALT + T then typing shell, this is not needed)
• ChromeOS flex installed

How to patch

1. Boot live linux usb after installing ChromeOS flex
2. Ensure you have a internet connection
3. Download latest binary from releases tab
4. Run sudo crimsonMoon -p /dev/sdX replace sdX with your drive, might also be nvme0nX NOT THE PARTITION, THE DRIVE ITSELF
5. Assuming no issues, patching success

Now, if there were issues:

• if it tells you to dd partition 12's data onto a usb, do it... e.g:sudo dd if=/dev/sda12 of=/dev/sdb bs=4M
• take into consideration that sda12 and sdb will be replaced by the actual 12th partition and the actual usb
• READ THIS FOR THIS ISSUE
• when you goto re-run the command, regardless of the usb's numbering or name, put a * after it with no spaces, that tells the program to work stuff a little differently and output different stuff. it will not work if you do not do this
• I personally do not know the exact root of this issue nor what devices it will affect, i know for sure the MacBook Air 7,1 is affected if your using the stock ssd

Installing

• Requires dev mode enabled

How to install

1. Boot into chromeOS if not already
2. Ensure you have access to the shell (CTRL + ALT + T then typing shell)
3. Download latest binary from releases
4. Move it to /usr/local/bin
5. Run sudo crimsonMoon -i to run init for the first time, will get some warnings but everything should resolve itself
6. Have fun!

Commands

-bb Backs up current boot animation currently set

-sb Sets boot animation, requires arg pointing to the folder with the files

-i Does init work, should be put into ~/.bashrc for best effect

--install Installs the given script/program. possible programs: (chromebrew)

-p Patches ChromeOS boot partition to enable dev mode

-h Help menu

Boot animations

Existing examples

stock chromeos flex here

troll face (static): here

troll face (animated): Coming soon?

Making your own

1. Make folder for the animation files (required)
2. Put animation files/frames/pictures into the folder
3. Name the files as boot_splash_frameXX.png, XX being the number, starting at 00, then 01 etc, (must be 31 frames as of chromeos 109, if older check)
4. Make text file called frame-interval and put the frame interval in there (3 is generally safe but adjust if you dont know and it looks weird)
5. Run sudo crimsonMoon -sb /path/to/folder

Building

1. who buildin this? 💀
2. its nim, nim c FILE

TODO

grub changes? (theme, menu, etc)
