Android 13 and SailfishOS on Xperia 10 III

Devices
69

You do it in recovery. So the procedure for the 10 III is as follows:

  1. flash hybris-recovery.img to both boot_a and boot_b slots:
fastboot flash boot_a hybris-recovery.img
fastboot flash boot_b hybris-recovery.img
fastboot reboot

  1. go to recovery (by simply rebooting the device)

  2. telnet to the device from your computer:

telnet 10.42.66.66

  1. select option 3) (shell), then enter your security code

  2. mount your microSD card (at least 105 GB of free space is needed for an uncompressed backup):

mount /dev/mmcblk0p1 /mnt

  1. do the backup:

dd if=/dev/sda79 of=/mnt/backup.img bs=1M

It may take 40+ minutes (or even more than one hour with a slower memory card). No progress is shown. If you would like to see progress, open another telnet connection and type:

watch -n5 'kill -USR1 $(pgrep ^dd$)'

This will show progress every 5 seconds.

  1. When backup is complete, unmount memory card:

umount /mnt

and then exit recovery mode.

Finally, flash the normal hybris-boot.img to both boot slots:

fastboot flash boot_a hybris-boot.img
fastboot flash boot_b hybris-boot.img
fastboot reboot

That’s all.

The backup can be restored the same way as you created it, i.e. by typing:

dd if=/mnt/backup.img of=/dev/sda79 bs=1M
