I’ve just bought a Fairphone 2 (the one with the brand new camera) and already wanted to install the Fairphone Open 17.10.1 OS.
I managed to start the phone on fastboot and launch the unix script.
Everything went smoothly (it’s upgrading the phone then ask to press enter to reboot the phone) but after rebooting and seemed to update normaly the phone stays stuck to “Android Update : Parameters preparation in progress…” message. I’ve waited about 20 minutes but didn’t change anything.
I already succeed in installing the last image of Android 6.0.1 so it makes me think that I’m able to install an OS with the fastboot way.
Thanks for any help
