Not so long ago after my Kies firmware upgrade failed, I had to get my phone fixed by the repair shop who told me that they had installed the latest version of Froyo. PDA:JW4/PHONE:JW4CSC:JW5(CPW) – as ICS is/was not available yet.
With this complete I was unhappy about the live wallpapers supplied as std so I downloaded a few from "play store" which I tried along with Launcher Pro.
It was then my phone started to lag really badly so uninstalled/deleted all the live wallpapers and LauncherPro and installed Zedge.
My phone is still really laggy and it's driving me mad. It gets better for a while after I’ve switched off and on again but I need to do this twice a day otherwise the lag gets too bad, despite installing Android Booster.
I think I need to root my phone but am really unsure what and how to do it.
Looking at a youtube tutorial showing the following, which option should I choose:
"reboot system now"
“Apply sdcard:update.zip” – I’ve not downloaded any update onto this
“Wipe data/factory reset” – will this wipe my latest version of Froyo?
“Wipe cache partition”
Is there an idiots guide on how to root somewhere? Or am I barking up the wrong tree?
Can someone please help as I’m just about to throw it at the wall.
