Hi.
After updating to 2.0.3.11 I started to install patches, it was no errors at all. But probably one of lockscreen patches did something and after lipstick restart I see only clean and beautiful ambience image :D No lockcode, no status bar, nothing. I can't access to the phone and sadly to say wifi connection was disabled before (can't ssh and restore changes).
I successfully connected to Recovery (0.3.1), choose option 4 to start shell, but now I probably need to mount fs because when I run command to revert patch, I get this message:

[OK] Code accepted.
/ # /usr/share/unapply-all-patches.sh
sh: /usr/share/unapply-all-patches.sh: not found
/ #

after /usr it can't auto-complete other folders (/share etc..). It doesn't see nothing, except:

/ # ls -l /usr/
drwxr-xr-x    2 0        0                0 Jun 16 09:12 bin
drwxr-xr-x    2 0        0                0 Jun 16 09:12 lib
drwxr-xr-x    2 0        0                0 Jun 16 09:12 sbin
/ #

PLEASE, can someone explain me what I need write after access, that will allow me to run my command ?
Thanks

Ok. Here I found how to mount it (https://together.jolla.com/question/22079/howto-all-computer-users-recover-or-reset-a-device-that-is-stuck-in-boot-loop/?sort=votes&page=1).

 mkdir /mnt/rootfs
 mkdir /mnt/sd
 mount /dev/mmcblk0p28 /mnt/rootfs
 mount /dev/mmcblk1p1 /mnt/sd

Now chroot to this:

chroot /mnt/rootfs

now you should "be" in your normal sailfish file system and should be able to run your script
To unmount, just run this commands:

umount /mnt/rootfs
umount /mnt/sd

Thanks to @till :)
Problem solved!

recovery mode is not the normal sailfish file system, you have to mount that first indeed.

what I've done (from memory, might have forgotten something) in such a situation was:

1) mount /dev/mmcblk0p28 to somewhere, for example /mnt:

mount /dev/mmcblk0p28 /mnt

2) bind-mount /dev, /proc, /run,/sys into /mnt:

mount -o bind /dev /mnt/dev
...
mount -o bind /sys /mnt/sys

3) chroot into /mnt:

chroot /mnt

now you should "be" in your normal sailfish file system and should be able to run your script

Be careful, you might brick your device/loose data if you do such things, and check what the commands do in advance

Thanks, I updated my question (already found), but can you tell me if I need umount when I'll done ? If yes, what the correct command ?
Thanks

Schturman ( 2016-07-22 16:35:15 +0300 )edit

you can unmount with

umount /mnt

but if you perform a reboot, that's not neccessary

Hi to all...
Sorry for reopen, but I have a question... How I can access to /home/nemo?
After " chroot /rootfs" I can see only empty /home directory...
And another question is it possible to be a user (nemo) in shell ? after "chroot /rootfs". If yes, how ?
Thanks

it depends on device model. on jolla 1 you need to mount btrfs subvolume, on jolla c and tablet you need to mount home partition from lvm.

Please, can you provide a full/correct command like "mount /dev/mmcblk0p28 /mnt/rootfs" for both types of devices (Jolla1 and C/tablet) ?

jor Jolla 1 you do:

mount -o subvolid=0 /dev/mmcblk0p28 /mnt

For Jolla C do:

mount /dev/sailfish/home /homefs

coderus ( 2017-04-23 20:11:55 +0300 )edit

Thank you very much!
Now I can see my files in nemo dir, but I still can't use dconf commands like read or reset specific dconf key... I get errors like this:
/homefs/@/root/rpmbuild # dconf read /desktop/lipstick/jollastyle/notifier1 sh: dconf: not found /homefs/@/root/rpmbuild # su -l nemo -c "dconf read /desktop/lipstick/jollastyle/notifier1" su: unknown user nemo /homefs/@/root/rpmbuild #
Any idea ?

dconf will not work until you boot sailfishos

Sorry, but I should reopen this question...
I'm trying to do the same on Jolla tablet, but when I trying to mount, I get this error:

 # mkdir /mnt/rootfs
/ # mount /dev/mmcblk0p28 /mnt/rootfs
mount: mounting /dev/mmcblk0p28 on /mnt/rootfs failed: No such file or directory
/ #

Probably on tablet it's a different... Can someone tell me what the correct command for mounting rootfs and sd on Jolla tabet ?
Thanks

Find answer by my self... After choosing Shell, I can directly run:
chroot /rootfs
