I updated my Fairphone 3 to the latest version: 0.12-p-2020093076095
After downloading and installing I had to restart my phone, but it doesnt work anymore.
After starting I get the message: “Your device is corrupt. It can’t be trusted and my not work properly.”
Then I get to the recovery mode with the message: “Can’t load Android system. You continue to get this message, factory data reset and erase a device.” I only have two options “Try again” and “Factory data reset”.
What can I do now, without loosing all my data?
