How to enter flash mode
Fastboot mode
With the phone powered off, hold the power key until the phone vibrates, then press the volume down key.
Unisoc emergency flash mode
Power on or reboot the phone with the volume up key held and connect with a flashing tool.
See https://sailfishos.wiki/books/jolla-c2/page/flashing-the-jolla-c2-using-the-unisoc-flash-mode for more information.
Installation
Backing up the Sailfish OS boot image
Enable developer mode on Sailfish OS and copy /boot/hybris-boot.img
from the phone using SSH.
Using pmbootstrap
Follow Installation/Using pmbootstrap and install to an SD card. When asked for the device's vendor/codename, select jolla
as the vendor and c2
as the codename.
To boot the device from the SD card:
- Enter fastboot mode (see #How to enter flash mode)
- Run
pmbootstrap flasher flash_kernel
to flash a boot image containing U-boot as a secondary bootloader - Run
fastboot reboot
pmbootstrap flasher flash_rootfs
is not recommended as it will overwrite the preinstalled Sailfish OS, requiring a complete reinstallation (not documented here).
Booting Sailfish OS
To boot Sailfish OS again, enter fastboot mode and run:
$ fastboot flash boot_a hybris-boot.img
$ fastboot reboot
