I have just updated my jolla and wondered how do you unlock the bootloader, in the release notes for the update it says about users being about to unlock the bootloader just wondered how one would do it

Instructions for those on and with Windows 7:- Jolla reboot loop solution for windows 7 owners.


You will need telnet. This is not installed by default so :- Open Control Panel => Click on “Programs” => Select “Turn Windows Features on/off” Then select telnet features.

You need to ensure RNDIS is installed

Best guide I found was here:-



Then with Jolla off press the down volume key and keep it pressed Now press the power key and when the jolla logo appear release all keys. Connect USB lead


Type telnet in the windows start menu search bar Telnet window will open type "telnet"

Jolla Recovery v0.2

Welcome to the recovery tool!

The available options are:

1) Reset phone to factory settings

2) Reboot phone

3) Bootloader unlock [Current state: locked]

4) Shell

5) Try btrfs recovery if your device is in bootloop

6) Exit

Type the number of the desired action and press [ENTER]:

I then chose 3 to unlock the bootloader and hey presto she was unlocked :-)

@ReflexDarky The link for RNDIS installation, isn't working. This is the correct link; http://developer.toradex.com/knowledge-base/how-to-install-microsoft-rndis-driver-for-windows-7 Regards,

How do I relock the bootloader? (after having inadvertently unlocked it, then inadvertently bricked my Jolla, even a factory reset didn't relock the bootloader)
