Good Morning Ladies and Gentlemans!

Since Jolla have some financial Problems atm, i think it would take some time till we see any newer version than 2.0.0.10, i want to play a little bit with Nemo Mobile on my Nokia N900.
Tha latest version that i found for N900 is: 0.20130620.0.1
My question is now?
How can i update it?
Setting the

ssu re latest

doesnt find some newer packages.

Setting the

ssu flavour devel

find approx. 480 packages but during the installation the n900 switch off and after the restart it runs worse than bevor update.
Is there a good starting point to bring nemo mobile to the newer stand and play a little bit with it?

I dont like the Plasma UI, so i didn't took the image which is linked to the Nemo/Mer Wiki. It seems also be older than
0.20130620.0.1

Thanks!
