I follow this guide to install Sailfish on my N950.

I don't know where is localized Sailfish on my N950?

/dev/mmcblk ???

How can i know?

And I want to replace the old version with a new version how can i do ?

EDIT:

On my ubuntu system:

Delete old sailfishOS:

rm -frv /media/Alt_OS/*

Now Install new 0.37 sailfish OS:

tar -xvjf sailfish .tar.bz2 --numeric-owner -C /media/Alt_OS/

I have a big problem now the version is not stable

What is the best last version for N950? 0.37 mode in landscape and a lot of bug impossible to see
