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:
- Shutdown the device and remove all cables and the 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
telnet 10.42.66.66
- 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 might be too small). The sdcard will show up as "/dev/mmcblk1"
- Mount the sdcard partition to a directory.
mkdir /tmp/phone-backup; mount /dev/mmcblk1p1 /tmp/phone-backup
- dd your system to an image file on the sdcard.
dd if=/dev/mmcblk0p28 of=/mnt/backup/jolla-fullBackup.img
- When the disk image is made, unmount the sdcard.
umount /tmp/phone-backup
Restore:
- Telnet to the device like before
- Mount the sdcard to a partition again
- dd the backup image to the device
dd if=/mnt/backup/jolla-fullBackup.img of=/dev/mmcblk0p28
- Reboot
Flashing mode
The Jolla phone uses fastboot from the Mer project rather 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 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
An IP address will be assigned automatically.
You can now use SSH to connect to the device on 172.16.42.1
.
