Hi there

Two weeks ago I recived a used Nokia N9. For experimentals I tried to install sailfish OS 1.0.2.5 with the informations from:
http://wiki.maemo.org/Sailfish

I reflashed my Nokia, installed openmode and because the dead repository from Nokia, I tried the N9 RepoMirror to activate the developer mode. This worked very well. At least there was Sailfish OS running.
Then I tried to reflash my Nokia N9 and would like to activate the developer mode. But after reflash my Nokia N9 five times ago, I can't use the N9 RepoMirror.

What I do:
1) reflash
2) start up (Settings German or English, Region time zurich), activate WLAN
3) go to settings > installation > activate ~"allow to install from other source" (or what ever).
4) go to openrepos.net and search for N9 RepoMirror
5) download the Version 0.6.0 or 0.7.2 (Problem still is the same)
6) install n9RepoMirror
7) go back to settings > application > manage application > update tab > search for update. My Device is up to date. (*yay...*)
8) in security I try to activate developer mode, but all times since the second reflash, I have the message: Can't install. Unable to trace installation package dependencies.

Where is my fault?
