Installing the MicroSD compatible bootloader is as easy as downloading the Installer.apk, installing it and running it on your RG405.
Running the installer a second time will restore the original bootloader.
To create a bootable MicroSD card:
- Format it with an exfat filesystem
- Create a boot folder on it
- Copy an OS init script of choice into the boot folder (ex. GarlicOS)
- Extract an OS rootfs file of choice into the boot folder with 7zip (ex. GarlicOS)
To boot a bootable MicroSD card:
- Make sure your device is powered off and not plugged in
- Hold down the power button
- 1.5 seconds into holding the power button, hold down the home/back button as well (you are now holding down two buttons)
- Let go of both buttons once the Anbernic logo is visible on screen
