Probably try another one too...
Think I've had my phone for around a year now and it's been Rooted for most of it's life with me. Think it came with ICS and I stuck some firmware that quite possibly was a version of JB.
It stayed like this for many months until one morning after waking with cold feet I pondered, "I shall flash my phone once more".
And so the journey began (sorry, been watching The Lord Of The Rings).
Anyway, after sticking Recovery on. I've now tried several firmwares. I'm no pro and even after a year with this phone, still no expert on it's native settings or capabilities but do know what I like.
Some of the firmwares I've tried I've not liked, some I've tried may have had some sort of Bug very early on or possibly an error from my methods of flashing. Those firmwares were changed for another and quite quickly too.
And this is I guess the point. As my phone stands now, with ClockworkMod Recovery v188.8.131.52, I can quickly change firmwares.
I have settled on one now but I've also seen some quite nice ones that I'd like to spend more time with. For now though, I'll rest up and get a better long term feel for the one I'm with now
