Really need urgent help with my iphone.

[jake3340]

I have an iphone 3g and once I was playing around with it trying to remove some apps I had. Somehow I managed to screw something up and the iphone decided to break for me. Basically this is whats happening, when I turned the iphone on it shows the apple logo then goes to a black screen where the light of the iphone screen is still on. After a few minutes the iphone decides to restart and repeat the process all over again. I cannot do a restore due to the fact that the iphone just keeps restarting and thus it reconnects the USB over and over aborting the restore. Can someone please help me here ?

Plug it into the computer, then hold power + home buttons for 8-10 seconds. The phone should now be permanently off. You should hear the computer high-low USB disconnect sound as confirmation.

[jake3340]

I did that but theres no point in it, when I turn it back on it just happens again...

[Mes]

Keep trying, maybe you're not holding the buttons long enough.
If you still can't get it, unplug from power or computer usb, and try again.

the phone clearly goes off with it, but I doubt it has anything to do with that it could be I messed up some software in the phone, Is there a way I can reinstall it ? Restore keeps getting me the 3194 error

[Mes]

Error 3194 means you need authorization to restore software. For a 3G, The current version 4.2.1, 4.1, and any 3.x iOS are authorized by Apple. Old versions require saved SHSH blobs. Use Tiny Umbrella 'Save SHSH' to see whats available.

What version are you trying to restore?

[jake3340]

3.0.1

[Mes]

Open Tiny Umbrella, click advanced, ..uncheck.. 'Set Hosts to Cydia on exit', exit Tiny Umbrella. Try again.

error 2003 now :S

[Mes]

Error 2003 is a USB connection problem or a Sn0wbreeze ipsw error.
What are you trying to restore and how are you doing it?

[jake3340]

I just clicked the restore and update on itunes...

[Mes]

Those buttons try to load the current firmware. For a 3G, that's 4.2.1.

[jake3340]

So what can I do just to reinstall my current firmware ? I remember reading that Itunes doesnt allow that or any downgrading.

[Mes]

Do you want to update to the latest 4.2.1? It's slow, 3.1.3 is best on a 3G.
Do you need an unlock? Are you an AT&T customer?

[jake3340]

my phone was jailybroken and unlocked im not an at&t customer they dont exist my country (Malta) I just want my phone working again haha 3.1.3 is ok or even how it was.

[Mes]

I need to go now, if you can wait 1 hour, I will come back with instructions.
In the mean time, search similar threads for "3G 3.1.3 restore"

Restoring iOS 3.1.3 on a 3G is easy and retains your unlocked baseband for use with any SIM.

Download iOS 3.1.3 and 3.1.2 firmware ipsw's, Tiny Umbrella, and redsn0w 0.9.4
Start iTunes, hold shift down and press restore button. A window opens, select 3.1.3.
If iTunes reports error 1015, open Tiny Umbrella and press 'exit recovery'. (not fix recovery).
Done with stock 3.1.3 restore

Start redsn0w, select 3.1.2 (not 3.1.3), check Cydia, continue ...
Done with jailbreak.

Open Cydia, install Ultrasn0w.
Give Cydia plenty of time to finish (20 - 30 min, or more).
Done with unlock.
