IPhone 3gs stuck in recovery mode?

For months I've been trying to get my old iPhone to work. You see, my mother, being curious and completely incompetent when it comes to technology synced my phone to her iTunes. This resulted in my iPhone going into recovery mode (error 1015). I've tried everything, literally everything. No matter what program I download, what video I watch, or what advice I take, it always stays in recovery mode.So, being sick of all this, I thought I'd get some help from people that I can get some relatively reliable feedback from.

Here are the details:
+ 8GB of memory.
+ It hasn't got wet/been dropped and worked fine before.
+ I've used redsnow, cydia, pwngetool, and a whole bunch of those useless programs.
+ I don't care about the iPhone content, I just want it to work again.

So please, as my last resort, I beg that someone gives me something that works.

It's easy to get out of iPhone recovery mode with a hard reset. To speed things up:

1. Disconnect your iPhone 3 GS from the computer.

2. Hold down the Power and Home buttons until you see the boot logo

3. When you see the boot logo, let go

4.Wait a while for the iPhone turn into normal state.

Be careful since it may lose your iPhone data in the process. In the event of iPhone data loss, you can use iTunes to restore your data if you have iTunes backup, if not any backup is available, you can search a third-party utility to recover the lost data, something like Tenorshare iPhone data recovery.

So take it easy, you won't lose much. Just go ahead!
