Rooting the CR48
- You need to be somewhat versed in Linux for any of these mods.
- Turn off the Cr-48. Make sure you have a pen nearby or this is going to be difficult.
- Flip the Cr-48 over.
- Remove the battery.
- Right beside the battery contacts there is a small bit of black tape. Take the tape off.
- There is a white switch under the tape. For user mode, the switch is away from the battery contacts. Use your pen to switch it towards the contacts.
- Put the battery back in and start the machine. There’s an ominous message but you can hit CTRL+D to get past it. If you do nothing the device will eventually beep and start the process into developer mode.
- The C-48 will wipe itself and replace the image with a developer copy. This takes 5-6 minutes.
- You’ll need to go though the initial setup process again.
- Once you get logged in, you can hit CTRL+ALT+T to get to the terminal.
- While you can get to this shell in user mode, this terminal offers an extra command to use. To see all commands type “help”.
- Type “shell” to drop to a full bash shell. You’ll be the special user named chronos.
- Type “sudo su”
- Now that you've rooted, you also need to make the root partition writable, and turn off boot verification.
- Open a shell (CTRL-ALT-T, then type shell)
- Open a shell again (CTRL-ALT-T, then type shell)
mount -o remount,rw /
mount -o remount,exec /mnt/stateful_partition
- If you don't want to remount the stateful partition after each boot, you can follow Make the /mnt/stateful partition exec friendly
