Miyoo Flip Install - TheGammaSqueeze/GammaOSCore GitHub Wiki
Install guide
Miyoo Flip users will need to use the GammaLoaderMiyooFlip.zip package in the release page to install the dual boot bootloader via the stock firmware:
- Extract the contents of the package to the root of a FAT32 formatted SD card, insert this into the left side SD card slot next to the volume buttons.
- On your Miyoo Flip, go to Apps, then open the "Gamma Bootloader Installer" application.
- The device will reboot a few times with progress displayed on screen. Once back into the Miyoo menu, you can now use the GammaOS SD card.

**DO NOT USE AMAZON BASICS OR CHEAP BRANDS. These are unreliable. **
The OS card slot on the Miyoo Flip is on the right side of the device, next to the power button. If you don't get any boot the first time you insert the GammaOS card (blank screen, green LED), eject and reinsert, and restart the device.
In case your device does not boot after installing the GammaLoader, try these unbricking instructions: https://github.com/spruceUI/spruceOS/wiki/16.-Miyoo-Flip-Unbricking
