Linux users: How to solve "Jolla reboot loop / phone stuck" problems.

I will will add Linux instructions only to make this complete. In linux you don't need to do much to get it to work, actually everything should work out of the box.

• Before we start the device should be turned off.
• Push and hold the volume down button now push and hold the power button until the phone vibrates then release all buttons.
• Plug in the USB cable into the computer and the Jolla JP-1301.
• Your device should show up as an ethernet device for me it was eth2
• If you are using a modern desktop Linux, the device should be configured automatically and you can now skip next step and move to telnet command.
• Connect by DHCP, how you do this is up to you and provided tools on your Linux distribution. (dhcpcd, dhclient, network-manager)

# dhcpcd eth2
dhcpcd[12401]: version 6.0.5 starting
dhcpcd[12401]: eth2: soliciting an IPv6 router
dhcpcd[12401]: eth2: rebinding lease of 10.42.66.80
dhcpcd[12401]: eth2: NAK: from 10.42.66.66
dhcpcd[12401]: eth2: soliciting an IPv6 router
dhcpcd[12401]: eth2: soliciting a DHCP lease
dhcpcd[12401]: eth2: offered 10.42.66.80 from 10.42.66.66
dhcpcd[12401]: eth2: leased 10.42.66.80 for 864000 seconds
dhcpcd[12401]: eth2: adding host route to 10.42.66.80 via 127.0.0.1
dhcpcd[12401]: eth2: adding route to 10.0.0.0/8
dhcpcd[12401]: forked to background, child pid 12443

• telnet 10.42.66.66

Windows 7 and Mac users: How to to solve the Jolla "reboot loop" / "phone is stuck" problem

What you need

• USB cable between PC and Jolla handset
• Windows PC: Installed telnet (see below)
• Mac PC: Installed Terminal (to be used as telnet client)
• RNDIS driver
  • Windows: Installed as below
  • Mac: Download from from http://joshuawise.com/horndis

Procedure

Windows: Enable telnet

Telnet is not installed by default so proceed as follows:

1. Open Control Panel
2. Click on “Programs”
3. Select “Turn Windows Features on/off” (in the vertical bar to the left)
4. Check-mark (tick) all telnet features.
5. Click [Ok].

Access the Jolla recovery tool

1. Mac: Make sure, RNDIS driver is installed.
   Download: http://joshuawise.com/horndis
2. Put the phone in "recovery mode":
   • Unplug USB cable.
   • Power off.
   • Remove the battery.
   • Reinstall the battery.
   • While pressing "volume down" button (keep it pressed), press the power key until the jolla logo appears.
   • Release all keys.
   Phone is now in recovery mode.
3. Connect Jolla to PC via USB.
4. Windows: Install RNDIS driver:
   Use the following guide with these exceptions: You can skip part 1 AND for part 6 choose "Remote NDIS based Internet Sharing Device" (re-installation may be required each time, you disconnect and reconnect the USB).
   http://developer.toradex.com/knowledge-base/how-to-install-microsoft-rndis-driver-for-windows-7
5. Start telnet connection
   Windows: Type telnet in the windows start menu search bar and telnet window should open.
   Mac: Start Terminal.
6. Within telnet: Type string o 10.42.66.66 (o is for open)
   The following menu should appear.

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].

For example: Enter 5 to recover from bootloop
5 Done Press [Enter] to reboot the phone... Rebooting... Connection to host lost. Press any key to continue...
Phone reboots and all is working well

Good luck.

Notes:

• For a description of the recovery tool options see this Answer below.
• For destructive options (e.g. resetting phone to factory settings which will return the device to ex factory state not only for Settings but the complete software version) your device lock code is requested. When you have mistyped it for 4 times, you have to wait for 24 h before you can retry. (Or reboot the device by removing USB connection and removing/reinstalling battery and then pressing the power button to reset the timer.)

How to connect to internet from your mobile in Recovery mode

(for (un)installing packages with zypper for example)

If the installation of some patched package or whatever bricked your phone, before reseting it to factory settings maybe you would like to try to reinstalling the official package and then maybe unbrick it. It worked for me after installing a patched lipstick (needed in the past for patchmanager) after update 1.0.7.16 (Saapunki).

NEEDS:

1. As Douglas Adams said: DON'T PANIC. Maybe you can repair it without losing anything. I am not responsible for making more damage to your device, I'm just trying to help. If you decide to follow this guide is your responsibility. Don't complain if it explodes and burns your dog.
2. A computer with GNU/Linux (Windows and MacOS should work too) and (obviously) an USB port.
3. Software for converting your PC in a router (for GNU/Linux iptables is included with the kernel).
4. Knowing to use the GNU/Linux terminal.

LET'S GO:

As described above enter

Recovery mode ---> Shell

As described above chroot to Sailfish filesystem:

mkdir /mnt/rootfs
mount /dev/mmcblk0p28 /mnt/rootfs
chroot /mnt/rootfs

(Then I mounted proc sysfs and /dev/pts but probably not needed):

mount /proc

mount /sys

mount /dev/pts

Do in the computer:

Then, to get Internet in the Jolla in Recovery mode in my GNU/Linux I activated package forwarding and a rule of iptables to route the packages received on the computer to Internet (so I converted my computer in a router. There is software to make this also on Windows and maybe on MacOS).

sysctl net.ipv4.ip_forward=1 
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Again in SailfishOS:

Add in sailfish almost one nameserver (DNS) to /etc/resolv.conf because if not, it can't resolve repo names to IPs (I wrote the Google one in this example, add wich you want, you can add more than one repeating the command with another one):

echo "nameserver 8.8.8.8" >> /etc/resolv.conf

Tell Sailfish that net packages for Internet must go through the computer (which we previously had converted in a router. In this example I assumed that Sailfish IP is 10.42.66.66 and computer IP is 10.42.66.67):

route add default gw 10.42.66.67

Profit! All is ready, you are in your SailfishOS filesystem and you have Internet connection.

In my case, I installed normal lipstick-qt5 so it removes patched one, with: zypper in -f lipstick-qt5

After finishing:

If you mounted sysfs proc and /dev/pts from the chroot, umount them:

umount /proc

umount /sys

umount /dev/pts

Exit from the chroot:

exit

Here I couldn't umount /mnt/rootfs because /sbin/busybox-static and other processes were using it (info got by "lsof /mnt/rootfs" command). I done "killall -15 busybox-static" and telnet recovery mode closed ( I made a stupid killall) and phone rebooted. So maybe you just need to...

Exit the shell and reboot the phone (yes, "exit" command again):

exit
Write 2 and press enter to get option 2 (Reboot) of the recovery menu.

Pray to Saint Ignucius

Hope yours now works!!! Mine did without having to reset it :)

@bockersjv: excellent howto, I was just about to write the same thing :-) A few more comments on the new recovery mode 0.2:

• Take care! It should be safe as long as you deal with a reset to factory settings or a reboot or btrfs recovery (see the updated Jolla Care article https://jolla.zendesk.com/hc/en-us/articles/204709607).
• The recovery mode looks like this:

 -----------------------------
      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]:

• bootloader unlock is usefull for kernel developers as it allows you to run fastboot commands for example to load custom kernels.
• If your phone is on rebootloop then you should 1st try number 5 and see if that helps, and if it doesnt help then factory reset should do the trick.
• If you want to access the Shell (point 4) you will be asked to enter your device lock code (screen lock code) if you had one set. You only get 5 attempts, no idea what happens if you mistype 5 times. If you misstype 5 times, then rescue mode will be locked out for the next 24 hours. This looks like this:

 Type the number of the desired action and press [ENTER]:
 4
 Are you really SURE? If you continue, this may void your warranty.[y/n]
 y
 Type your devicelock code and press [ENTER] key:
 (please note that the typed numbers won't be shown for security reasons)
 [OK] Code accepted.

• You're now root on the top level of your Jolla ! Remember you're in little kernel/fastboot mode now (see MTO thread http://talk.maemo.org/showthread.php?t=91885, specially http://talk.maemo.org/showpost.php?p=1399188&postcount=40). So, although you do have a busybox set of commands available, by default rootfs and sd-card is not mounted. So doing a ls -la gives you:

 / # ls -la

 / #

Thanks @whoever for adding the following comments:

If you want to access the rootfs and sdcard you can do:

 mkdir /mnt/rootfs
 mkdir /mnt/sd
 mount /dev/mmcblk0p28 /mnt/rootfs
 mount /dev/mmcblk1p1 /mnt/sd

And if you want to copy files over the usbnet then you can use netcat pipes to do so (google howto).

I have set a device lock at some point but this option was disabled and I wasn't using it. Now I got stuck for 24hrs after five attempts of wrong codes. Any ideas on what to do while waiting for the next 24hrs to try again?

**AND IF YOUR PHONE IS IN BOOT LOOP THAT CANT BE STOPPED WITH:

> Push and hold the volume DOWN button now push and hold the power button until the phone vibrates then release all buttons. And even removing the battery did not work then:

Push and hold the volume UP button + the power button until the phone vibrates two or three times, then without releasing ANY button slide your finger to volume DOWN key and hold until Jolla logo stays on screen permanently, then you are ready to plug the usb cable and go like it's described above.

Hi, my phone boots as soon as I touch the screen. I tried connecting via telnet; the recovery program is v0.1 and does not have the option to recover from bootloop. I tried resetting to factory settings but I have no clue about the device lock code. Wat do? Is it possible to update the recovery tool to v0.2 via USB?
