Backup the Jolla system

If you want to flash postmarketOS to your phone itself rather than an sdcard, it might be smart to first backup your system.

Backup:

  1. Shutdown the device and remove all cables and the battery
  2. Insert the battery while holding down the volume down button
  3. While still holding down the volume down button, press the power button till the phone shakes. If done correctly, the Jolla logo will be shown constantly in combination with the led lighting up white
  4. Plug in the phone to a PC with telnet installed
  5. On your PC, it should appear as a new network interface. Connect to it.
  6. If you see an USB device connected, but without network interface, try 
    $ sudo modprobe rndis_host
  7. Open a terminal and use telnet to get into the recovery 
    $ telnet 10.42.66.66
  8. A menu will be shown, press 4 and enter to get a shell. The device will ask for your devicelock code
  9. Insert a sdcard into your phone with a partition on it big enough to fit the system (make sure it isn't FAT32 formatted, as it can only store files up to 4GB big which might be too small). The sdcard will show up as "/dev/mmcblk1"
  10. Mount the sdcard partition to a directory. 
    # mkdir /tmp/phone-backup; mount /dev/mmcblk1p1 /tmp/phone-backup
  11. dd your system to an image file on the sdcard. 
    # dd if=/dev/mmcblk0p28 of=/tmp/phone-backup/jolla-fullBackup.img
  12. When the disk image is made, unmount the sdcard.
    # umount /tmp/phone-backup

Restore:

  1. Telnet to the device like before
  2. Mount the sdcard to a partition again
  3. dd the backup image to the device 
    # dd if=/mnt/backup/jolla-fullBackup.img of=/dev/mmcblk0p28
  4. Reboot

Reverting back to stock w/o backup

To install latest stock version you need to flash an image, because the recovery image of factory reset is not updatable. A decent version can be found here.

Flashing mode

The Jolla phone uses fastboot from the Mer project rather than Android. To enter fastboot shut down the device, then Plug in USB lead while pressing Volume Down.

USB connection

The USB connection works, but needs some manual configuration (as found here).

First, find the interface name using ip a. Then, we have to assign the device a mac address (replace the interface name with what you found from the previous command). 

# ip l set enp1s0f0u3 address 12:12:12:12:12:12

After some seconds an IP address will be assigned automatically.

You can now use SSH to connect to the device on 172.16.42.1.

Install to SD-card only

Its possible to install to sdcard and boot via fastboot without flashing.

  • Install to sdcard
    # pmbootstrap install --sdcard=/dev/XXX
  • Enter fastboot mode
  • Boot via fastboot
    # pmbootstrap flasher boot --cmdline "root=/dev/mmcblk1p2 androidboot.hardware=qcom user_debug=30 ehci-hcd.park=3 maxcpus=2 zram.num_devices=2"

If you see an error Booting FAILED (remote: 'access denied. need privilege!'), it means that the bootloader is locked. You need to unlock the bootloader by going in the recovery mode (https://talk.maemo.org/showthread.php?p=1556497 / https://jolla.zendesk.com/hc/en-us/articles/204709607-Jolla-Phone-How-to-use-Recovery-Mode):

  1. Turn off your Jolla device and remove all cables and the battery.
  2. Press and hold down the Volume Down button while re-inserting the battery.
  3. While still holding down the Volume key, press the Power key until Jolla vibrates.

You can now release both buttons. You have now put your device into Recovery Mode.

If you have a device lockcode, there could be an issue saying the code is incorrect even after typing the correct one (https://forum.sailfishos.org/t/jolla-recovery-v0-3-1-unlockable/8013/2) so you may need to disable the lockcode in Sailfish OS settings before unlocking the bootloader in recovery mode. If the bootloader is unlocked, it should display "Unlocked" in red on the top left when entering fastboot.

If your screen stays black after booting, it could mean that you have used an interface that is not supported: https://wiki.postmarketos.org/wiki/Category:Interface#Which_interfaces_work_where_.28and_which_interface_should_I_use.3F.29


You can reboot into fastboot again as root if reboot-mode is installed. 

# (sleep 2 && reboot-mode bootloader ) & exit

SIGILL in kernel log

Kernel log are flushed with these messages: 

sshd(3029) send signal 4 to sshd(3029)
sshd (3029): undefined instruction: pc=4038c98c
Code: 4770 ec51 0f1e 4770 (ffb0) 0300

This is due to probing of processor capabilities in libcrypt of OpenSSL. Its reduced by changing debug level to user_debug=30.

This also blocks debugging with gdb. Workaround can be found here <https://www.openssl.org/docs/faq.html#PROG17>.

WiFi

WiFi works with firmware and the original proprietary wlan.ko, which depends on cfg80211.ko.

It must be activated in this order (these steps may not be necessary and could be ignored): 

# echo 1 > /dev/wcnss_wlan 2>/dev/null
# sleep 1
# modprobe wlan
# echo sta > /sys/module/wlan/parameters/fwpath

You can use sudo nmtui to connect to a Wi-Fi network (nmcli can be used also: https://wiki.postmarketos.org/wiki/WiFi#Using_NetworkManager). You may see WiFi networks listed under 2 network interfaces, p2p0 and wlan0. The correct interface for WiFi is wlan0.

If you have problems to connect to a WiFi network with Network Manager (for example with a message "Error: Connection activation failed: (5) IP configuration could not be reserved (no available address, timeout, etc.)."), you can install dhclient (by adding it when running pmbootstrap init on your computer) and replace dhcp=internal with dhcp=dhclient below [main] in /etc/NetworkManager/NetworkManager.conf. Then you need to restart Network Manager with the command sudo service networkmanager restart (solution based on https://bbs.archlinux.org/viewtopic.php?id=232833 / https://forum.salixos.org/viewtopic.php?f=30&t=7284). Network Manager should then be connected to the WiFi network. If you still don't have access to Internet because there is no default route, you need to execute this command: sudo dhclient wlan0.

Modem

Firmware loads, but modem can't be enabled. Might be fixable, because it works for similar samsung-i9195 (#1054). To get more features working like the modem, the phone must be ported first to the mainline kernel (https://gitlab.postmarketos.org/postmarketOS/pmbootstrap/-/commit/2e30fa4281b43df769bd2546931fd63ba9857b53#note_846861351). 

# apk add ofono ofono-scripts
# service ofono start
# echo 2 > /sys/devices/virtual/smdpkt/smdcntl0/open_timeout
# /usr/lib/ofono/test/enable-modem

modem and modem_fw is loaded.
