Few months back, I've installed Jelly Bean on my LG 4X HD through LGPCsuite. It started lagging so much after that update, it's almost impossible to work with it. When I'm trying to call someone it takes about 10 secs to even start calling, not to mention how home screen lags after closing app etc. I've read here, on xda, that the best solution would be to downgrade to ICS. Anyway, I really didn't like ICS; camera is much better on JB then on ICS (it took blurry pics) plus some other things I really like more on JB. I have JB v20b and I was wondering: if I install v20a will lagging be less? I really want to use JB, not ICS. Plus, if someone can tell me how should I do that? Or tell me what would really be best solution. I'm kinda scared of installing custom rom, so I'm trying to avoid that. Plus, I'm from Croatia and could I install EUROPE OPEN ANEUBK VERSION firmware?
Thanks so much, I really hope someone will help me!
Plus, please don't mind if I'm asking some nonsense, I'm really new at this.
