If you already use TWRP or another recovery capable of installing zip files, you only have to download a flashable zip with emoji, boot into recovery and then install the zip. If you don’t have a custom recovery installed, follow the steps below.
- Install the Android Debug Bridge.
- Download a working version of TWRP to your PC.
- Download a flashable zip with emoji to your FP2’s internal memory - such as this one.
- Turn off your phone and boot to bootloader by pressing Power + Volume down.
- Connect the phone to a PC with a USB data cable and in a terminal on your PC, run
fastboot devices
to make sure your device is connected. It should show up as a series of symbols followed by ‘fastboot’. - Now, in that terminal run
fastboot flash recovery /path/to/the/image/twrp-3.3.1-1-FP2.img
Replacing the path with the path to your file, of course. - Now type
fastboot reboot
and before pressing Return, hold down the Volume up button on your FP2, and only then press Return. Your phone will boot to TWRP. - Use the slider to allow modifications, tap ‘Install’ and select your flashable zip file. Confirm and reboot.
That’s it!
Edit: changed link to zip to the one available from the WeAreFairphone github
