Online in the forum, in other section too, I found (in Arnova G2 general discussions) other roms different from the roms found in 7g2 section

Some of them appears to be compatible with 7g2 too..

So I thought it would be useful to list all roms working for Arnova 7g2, the ones in this section and the others too.

I think it will be good to have:
Pubblisher name, Android Version, Kernel Version and eventually their strong and weak points.. and the link to the topic where download it. So I go on with the one I'm using and actually the best one I used since now.

Oma
Android 4.1.1 JB
Kernel 3.0.8+
Strong Points: Very fast in the response and in application working, even Chrome that wasn't compatible with original firmware and didn't work with 4.0.3 ics, works very good.
Weak points: Tested Skype last version, it's the once app going slow.

I had this idea 'cause I found some 4.2.2 version (it seems unrooted) and some Honeycomb..

Added 11/08 19.41

Fenice
4.0.3 ICS
3.0.8+
Description: There are 2 releases of it, I tried both, the first for several mounths. In first works every app without problems (last version of skype is very fast). The second version accepted the adhoc module took from 4.2.2 by oma.
Weak point: It gets slow sometimes, on starting and if much apps are installed
