Re-start fresh, now that you are in recovery mode, reload the firmware that will allow you to start hacking/jailbreaking.
Only you know what is the version of your bootloader, baseband and firmware where you were stuck. You must start with the right combination so you can recover your iPhone from the current state that you left it.
That website is the best step by step hacking/jailbrekaing/downgrading/upgrading website for the iPhone available.
I have used its tutorials since the iPhone was first jailbroken, and I had no problems at all since then, I mean even when something go wrong I started over and it always worked from me.
The key is patience and follow the instructions without jumping from one step to another.
Post the history of your iPhone, or how it was when you started the last hacking attempt:
Firmware, Bootloader, baseband; jailbroken and unlocked state.
If you know also since you bought it, and how it evolved until Today, so we can help you better.
