Is it possible to clone a jolla device with dd?

I have two identical sailfish OS devices (Intex Aqua Fish) and want to clone one to another.

My idear is to use dd to a computer, and copy the image to the target.

Do someone have some experiences on the topic? :)

Edit: dd /dev/mmcblk0 via recoverymode to a sdcard and/or laptop. Everything worked fine! Thx for the help.

Note that you do not "clone" the device, but the partition (disk) only. And yes, its indeed possible.

Jupp, thats clear. I technical just need the main partition and will use the same SD card. Should work, shouldn't it?

It has been done with Jolla1 from recovery mode - be aware that it is a very good idea, not to say a requirement, to have both phones on the same version before you transfer (upgrade both to the same release!) - and in general, if you break it, you may keep the pieces. Also be aware that you need to go the proper LVM2 way if you are dd'ing any less than the whole physical device.

Just never touch the other partitions! And you should be good.

atm i just dd /dev/mmcblk0 to a sdcard .... and will restore it from there to the second device.

btw.: whats /dev/dm-0 and /dm-1 .. .around 2,3 gb and 11,2 gb=?

That are kernel device mapper raw blockdevices, do not touch. Should be equivalent to /dev/mapper/ stuff - you may snapshot the lvm2 logical volumes instead of dd'ing the whole device (needs lvm2 installed).

Here are instructions that work fine for Jolla1: https://together.jolla.com/question/81832/full-phone-backup-guide/?answer=107185#post-id-107185

The partition layout of the Intex Aqua Fish might differ though(?) since it is not btrfs.
