Update to Android 9 failed. The device does not boot properly anymore
Which version of the software are you running?
Updating from Android 7 to Android 9
What happened?
I started to update the Android 9 on my Fariphone 2. During the update, I saw an error message for a few seconds, then the phone restarted. The phone is now stuck on the black screen with the Fairphone logo.
Expected behavior
The update should have successfully installed Android 9
Is there a workaround?
- Try to flash the phone manually to the latest available Android 9 release.
NOTE: the first boot after flashing the phone can take a while. Be patient. - If the flashing operation is successful, but the phone still does not boot properly, you can perform a factory reset via recovery.
NOTE: the first boot after a factory reset can take up to ten minutes.
Need help with the manual flashing procedure?
Quick tips:
- If the phone is not being recognized
- If you are using Windows, you might be missing the correct drivers. Read this support article for instructions on how to check for driver updates
- Make sure the USB cable you are using is working properly
- If the flashing process fails while writing to the phone:
- Writing issue on the system partition (e.g. 'flash write failure'):
- Check your cables
- Make sure you are not using USB adapters or hubs
- Power cycle the device, then try again
- Parsing issue when flashing

(i.e.Couldn't parse partition size '0x'
)- You are likely using macOS or Linux
- You are using a locally installed version of fastboot which is too recent (yes, you read that right
😅 ) - If on macOS, use the
.command
script instead of the.sh
. This will use thefastboot
binary that comes with the package. - If on Linux, you'll have to downgrade to an older version of
fastboot
. Version29.0.1-5644136
or older should work.
