== 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.
== What works =='''Backup:'''
* Compiling # Shutdown the kernel from device and remove all cables and the jolla sources battery# Insert the battery while holding down the volume down button# 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# Plug in the phone to a PC with telnet installed# On your PC, open a terminal and use telnet to get into the recovery <pre>telnet 10.42.66.66</pre># A menu will be shown, press 4 and enter to get a shell. The device will ask for your devicelock code# 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 should provide everything might be too small). The sdcard will show up as "/dev/mmcblk1"# Mount the sdcard partition to a directory. <pre>mkdir /tmp/phone-backup; mount /dev/mmcblk1p1 /tmp/phone-backup</pre># dd your system to run wayland since that's what sailfish usesan image file on the sdcard. <pre>dd if=/dev/mmcblk0p28 of=/tmp/phone-backup/jolla-fullBackup.img</pre># When the disk image is made, unmount the sdcard. <pre>umount /tmp/phone-backup</pre>
== What does not work =='''Restore:'''
* Flashing, still need # Telnet to find the correct offsetsdevice like before# Mount the sdcard to a partition again# dd the backup image to the device <pre>dd if=/mnt/backup/jolla-fullBackup.img of=/dev/mmcblk0p28</pre># Reboot
== Flashing mode ==
The jolla does use Jolla phone uses fastboot from the mer Mer project instead of androidrather than Android. To enter fastboot shut down the device, then plug in the USB lead while holding down volume down. == USB connection == The USB connection works, but needs some manual configuration (as found [https://wiki.postmarketos.org/wiki/USB_Network#Assigning_an_IP_address here]). First, find the interface name using <code>ip a</code>.Then, we have to assign the device a mac address (replace the interface name with what you found from the previous command).<source># ip l set enp1s0f0u3 address 12:12:12:12:12:12</source> An IP address will be assigned automatically. You can now use SSH to connect to the device on <code>172.16.42.1</code>.
