Stuck in iphone recovery mode after reseting jailbreak

[feeswasted]

Hello all,
I'm new to the forums & new to iphone world.

Device: iphone 3GS. Firmware: 4.2.1
Problem: Reset data- now stuck in recovery screen with itune logo & usb calbe'

I bought used iphone & thought to reset all data & upgrade the software.
Since I want to make a fresh start & dont want previous owners records I reset it.
Once I reset all content & data, I was stuck in blank screen with apple logo (& danger/ghost-skeloton-like logo) It appears that its a jailbroken iphone.

After reading loads of stuff online (& MacRumors forums of course) I could bring it in recovery mode. & now in itunes I only can see summary tab & name & firmware details all wipe-out. except serial no.
Still in recovery mode: itunes suggested to restore & upgrade (which is what I want to do) but it failed to restore, I sometimes get error 1055 or 3194.
I know it's jailbreak so... yeah shoot me.
but is the any workaround? How can I restore or install and make it functional?
I dont mind wiping /formating all data or apps if there any.

Pleeeeeeeeeeeeeeeeessssssssssssse help me out here.
I read lot of similar discussions here.

Thank you.

One more thing:
I tried tiny-umbrella to get out of recovery mode.
But as I said there's no saved records either. Also tiny umbrella could not recognise device serial no. or name.

Also I dont mind getting out of jailbreak version.. In fact it would be great if I could cleanse iphone & come out clean.
Thank you.
