1 What is Recovery Mode?

The Recovery Mode is a tool built-in to the Jolla Tablet that allows you to recover your device from a critical or unusable state.

1.1 When might I need the Recovery Mode?

Below are example cases where you could need to use the Recovery Mode:

  • If your Jolla Tablet isn't starting up normally or at all, or for some reason you can't perform a device reset via the normal means in Settings, you can maybe do it in Recovery Mode.
  • Recovery Mode allows you to enter commands to the Tablet via commandline ("Shell") even if the device doesn't start up.
  • You can check the filesystem for errors and let Recovery Mode automatically correct them. With this you can fix instability and errors in the operating system and applications.

 

2 Setting up Recover Mode for the first time

These instructions are for setting your Windows-, Mac- or Linux PC up to be able to use Recovery Mode, and to teach you how to put your Jolla Tablet into a suitable mode for Recovery Mode.

2.1 Preparing your Jolla Tablet for Recovery Mode

1. Switch off your Jolla Tablet

2. Press and hold the Volume Down & Power button. Keep them held down until you see a Jolla logo on the display of your device.

3. In a moment you will see a view that reads "Droidboot", and a menu with the selection "Recovery". Move the selector to "Recovery" by using the volume keys. Confirm your selection by pressing the Power key.

4. Soon the text "RECOVERY: Connect USB cable and open telnet connection to address 10.42.66.66" will appear on your Tablet's screen.

Your Tablet is now ready for Recovery Mode.

2.2 Preparing your Windows laptop for Recovery Mode:

Do the following to install the “RNDIS drivers” and the terminal application properly (if you have not used Recovery mode before):

1. Connect your Jolla to your PC with a USB-cable.

2. Launch Windows Start Menu and right click on “Computer”. Select “Manage”.

3. Left click on Device Manager and find the Device "RNDIS" under “Other Devices”.

4. Right click on that device and select Update Driver Software.

5. When the window pops up (Windows 7 and 8) select “Browse My Computer” for driver software, then on the next screen, click on the bottom that says “LET ME PICK”.

6. Next you will be asked for the device type. Here you go down to Network Adapters – click on it. Select “Next”, then.


7. Then when it asks you to select manufacturer, skip Microsoft and select “Microsoft Corporation”.  NOTE: Windows 8 has only "Microsoft" - select that.

8. Then select “Remote NDIS Compatible Device”.

9. Select “Next”. It will say it is not safe, etc. Ignore this. Proceed to install it. Windows should show a message about successful update. Close it. “RNDIS” should appear now below Network adapters.

10. Next install Putty to serve as a Terminal application. Download it from http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe.

11. Launch Putty application on the PC. On the first screen of Putty select Telnet as the Connection type (default is SSH) and then enter and set Host Name to 10.42.66.66. Click Open:

12. You should now see the Recovery Mode menu on your computer screen:

This signifies that you are ready to perform a fix by using Recovery Mode.

 

2.3 Preparing your Mac (OS X) computer for Recovery Mode

To run the Recovery Mode on a Mac computer, you need to download the HoRNDIS driver but all other software is already on your computer.

1. Browse to www.joshuawise.com/horndis

2. Download and install the latest version of the driver. Please note any OS version restrictions noted with the driver:

3. After installing the driver you may be prompted to perform a system restart and receive a notification about a "Kernel extension not from an identified developer":

Please click OK on the pop-up and restart your computer if you are unsure should you do so or not.

4. Once the driver is installed, attach your Jolla to your Mac. (Note: Jolla must be in "Recovery Mode" before attaching the cable, see chapter 2.1)

5. Next you need to locate the Terminal application. To do so:

5a Open Finder
5b Click the tab "Applications" and open "Utilities"

5c Double-click the Terminal icon to launch it.

6. Once Terminal is open, select Shell > "New Remote Connection..."

 

7. Click on "Remote Login (telnet)" and then the + -icon to add a server.

8. Type in the address: 10.42.66.66 and press "OK".

9. You should now be in Recovery Mode, with the Recovery Mode menu visible on your computer screen.

 

2.4 Preparing your Linux PC for Recovery Mode

It is likely that you won't need to download any additional software to use Recovery Mode. Below we've used Ubuntu.

1.) Connect your Jolla Tablet to your PC. You will likely see a notification relating to a disconnect/connect and Ethernet/Wired connection:

2.) Open the Terminal application

3.) Type into the Terminal:

telnet 10.42.66.66

4.) You should now see the Recovery Mode menu on your computer screen.

 

3 Fixing your device with Recovery Mode

Now that your Jolla Tablet and your computer are set up for Recovery Mode, you are ready to run one of the Recovery Mode's functions:

1) "Reset device to factory state": the device is returned to factory settings and all data on the device (pictures, videos, applications, settings...) is removed as well as downloaded software updates.

This function wipes the device clean of data. Whether perfroming a backup before this operation via normal means isn't possible or fails, you can try backing up data in the Shell of Recovery Mode.

2) "Reboot device": the device is simply restarted.

3) "Shell": the command line which in itself is not a fix. It allows controlling the Jolla Tablet via textual commands, even if the device doesn't start up.

4) "Perform file system check": checks the filesystem for errors and lets Recovery Mode automatically correct them. With this you can fix instability and errors in the operating system and applications.

This function does not delete any data from the device.

5) "SSHD": allows commands to be entered into Recovery Mode via SSH-connections.

6) "Exit": whenever you stop using Recovery Mode, you should close it by using this function. After using this function, remove the USB cable and start your Tablet normally.

3.1 Using Copy-Paste with Shell commands

You may receive specific commands from Jolla Service & Support to enter specific commands into the Shell of Recovery mode. As every character and space counts, we urge you to use copy-paste whenever possible:

  1. "Paint" (select) the command from our message.
  2. Copy the command to the clipboard either by using your mouse or a keyboard combination (Windows: ctrl + c / Mac: command key (⌘) + C).
  3. In shell, simply (right) click to paste text.
  4. Execute the command by pressing Enter.
