h1. Safe mode If your device is stuck in a boot loop (the device is crashing during boot, endlessly) after installing or updating applications, it is possible to recover from that by booting the device into _Safe Mode_ which will disable all applications that are not part of the Replicant image. However this will purge all accounts, *including corresponding data*. Therefore, any not-yet-synced data (e.g. contacts, calendar appointments, etc.) which are bound to an account *will be lost*. Furthermore there is a bug #1986 in Replicant which causes the account configuration itself to be deleted as well. To boot into _Safe Mode_, you need to press and hold down the "Volume Down" button during boot: * It is enough to hold the button for approximately one second during the short vibration near the end of the boot sequence. * It does not matter if the key was hold down all the time nor if other keys are pressed/held as well. You will then see a small dark box at the bottom left screen reading _Safe Mode_ if you have been successful. Just reboot your device to disable _Safe Mode_ again.
