How to enable Developer Mode

Jukka Romu -

NOTE: Please be advised that in the Developer Mode you can enable features that, when used incorrectly, can cause permanent damage to your device and/or content.



Turning Developer Mode on

You will need the Internet connection and a working Jolla account in your phone to turn the Developer Mode on.

1) Visit menu Settings > Developer tools.
2) Tap on "Developer mode" to turn it on. The phone will download some packages and install them to the phone. This will take few minutes. The installation is ready when the switch light ("LED") in front of Developer mode is turned on.
3) Now tap on "Remote connection" to turn it on, too.
4) Tap on the "Set password for SSH and root access" line and type a simple password - we call it the "SSH password" for short now. Tap on 'Save ' to save it.
5) Close the Settings app.

Your phone is now in the Developer Mode.

Using Developer Mode

A. Terminal application

1) View the application launcher grid. In the end of the grid you have now the Terminal application, providing the "command line".

-All commands shall be terminated by tapping the Enter key
-Linux command interpreter is case sensitive, i.e. you must type the upper and lower case letters correctly.

2) Get the super-user rights (if you need them) by issuing the command below in the Terminal


Use your SSH password here. The characters you type are not shown on the screen.
Note that you must be careful with the super-user rights or else you might break your phone. Follow our instructions in other help articles and type (or copy/paste) the commands precisely in the same way.

B. SSH connection

Typing complicated commands at the tiny Terminal is error prone and can lead to serious problems at worst. A safer way of entering commands is to do it at a terminal app running on PC, after creating an SSH connection from PC to Sailfish OS device.  You can namely copy the commands (one-by-one) from our articles and then paste them to the SSH terminal.
