I post this as answer just to warn people copying their /dev/mmcblk0p28 and sending it to other people!
It contains sensitive user data
For example Wifi Passwords and /home/nemo!
[root@Jolla nemo]# btrfs subvolume list /
ID 257 gen 86423 top level 5 path @
ID 258 gen 86420 top level 5 path @home
ID 263 gen 33 top level 5 path factory-@
ID 264 gen 34 top level 5 path factory-@home
[root@Jolla nemo]#

In order to increase visibility of my comment above ... now as 'answer'
a backup of that partition is easily made with i.e.:
> devel-su
> dd if=/dev/mmcblk0p28 | ssh username@pccomputer "dd of=somefile.bin"
@phantomr6 - I have a copy of my mmcblk0p28-partition (but not after factoryreset) on a webspace, I'm still looking for a way to send you a private message for the link - any ideas anybody?

i got the same problem, my phone sticks in the bootloop i think, and the recovery mode coulnt fix it. Could you send me the image too, please.

But wasn't recovery menu ment to help out on situations like this? Though i'd like to now how this dd backup works, i'm fed up to always start anew after factory reset. Sorry, for no help.
veeall ( 2014-09-14 00:30:31 +0200 )edit@veeall For me it seems that recovery mode (respectively the factory reset) only resets the settings and the /home directory, but does not "reinstall" the hole OS. So if you did some changes in the deeper system, they will probably not get cleaned by an factory reset.
breiti_oi ( 2014-09-18 22:21:55 +0200 )editI would also be interested in such an copy :)
No backup yet!(
phantomr6 ( 2014-09-19 10:05:45 +0200 )editwell, maybe i could make you a copy, but as i said, it wouldn't be a "fresh install". for example i activated the low power mode on my jolla, and after the factory reset it's still activated. so it seems only to reset home. what you probably need is a backup of an factory new device.
breiti_oi ( 2014-09-19 22:33:34 +0200 )editplease make me a copy of your partition! low power mode will not prevent. You will get backup size 14,1gb, you will need to mount network folder in Jolla and to do a backup! Sorry for my english(
