Straight Talk Samsung Galaxy S2 won't charge?

[Leelouster]

As of last night, whenever I try to connect my phone to either my outlet charger, my xbox, my computer...anything, it never even charges. The icon on the screen still says, "Connect your charger" even if it's connected. The sound doesn't even come on, and the battery icon doesn't move when it's connected (obviously, because it's not charging lol). But the only way I can use my phone is by charging my battery first. (Luckily I had a spare battery that I had already charged) and now I'm looking to buy a battery charger so I can switch battery's whenever I want. It'll be a pain in the a**, so there must be a way to fix it. Sometimes when I disconnect my charger, the icon pops up saying, "USB Connected". I've tried 4 different chargers also, and still no luck. I still haven't bought my warranty so I don't know if I can still do that and exchange it.

Any suggestions? I already tried different battery's, removing the battery for a couple of minutes, charging the phone while it's off (it seems to work but the battery icon goes from 1/4, 1/2, 3/4, and to full, then back to empty, and it does it again, but it freezes and it takes awhile and then finally it does it again, but it doesn't really charge.)

My phone IS rooted, and I have ShoStock3 with Clockwork Mod. I'm thinking of reverting back to my Clockwork Backup from March but I don't think that'll work. I don't want to loose anything from my Internal Storage that I may have stored.

Please help

Is there any way I could fix it? And is there anyway I could clean it if it's dirty?

By the way, what's that charging port USB Dock Connector for? I've never seen them before so I dont know what they're for or how to use it.

Edit: Nevermind, I did my research and found out what it's for lol. I don't think I'll want to go that route, I hate taking apart computer's or phones because I'm not good at following instructions and I sometimes loose the parts lol.

This has happened to me three times. It's the charging module. You have to get it repaired I'm sad to say.
