Previously I used Froyo and rooted it with Z4root and applied lag fix. I was quite happy and I got benchmark around 1800sh. When official gingerbread update is available, I unroot the phone and upgraded to gingerbread via Kies.
Below is my current version:
Firmware ver : 2.3.3
Baseband ver : I9000XXJVQ
After the upgrade the benchmark score is about 954
. I also found the phone is slower and when I play few games (particularly Mycountry (like sim city)), it often hang and restart by itself. I only can play for 1-2 minutes. But if I run memory optimizer to kill few running apps, then I can play the game bit longer.
I also try to root using gingerbreak (I think this is the easiest for a dummy like me), but nothing happen, it displays rooting in progress and takes more than 20 mins ( I have tried 3 times).
Does anyone know how to solve this? I would like to root (easy way) and improve my phone performance, at least back like when I was on Froyo.
