I installed Omega V3 6.0.1 yesterday.
The phone is far faster now. Very stable.
Battery life is massively improved. I normally hit 25% by now. It's on 60% right now!
Wowzers
Do you have a linkie to that ROM and a guide on installing?
May throw that on my N4 when my N7 turns up. Have not rooted it yet as need to use the mobile banking apps which throw a paddy if they are installed on a rooted phone
. Flashing ROMs like this usually give you root access so you won't be able to use your banking apps like you said, I have yet to find a working root hider app.
