My boss have an iphone (1.1.1)version, jailbreaked and unlocked (by someone in Singapore, I'm also not so sure by which way of soft unlocked), several days before when he using Viaticus Volatus method (he purchased this via internet http://iphoneinfused.com/features.cfm )and they send him a link wihch descriped how to unlock 2.0 version, on the way do it, he failed, when I try this way, I also failed , first when connect with iTune, shows that " It seems that the sim car are not supported", then press home button and power button at same time, release power button in 10 seconds, then hold Option with click Restore, it shows Restore, then when restoring, failed to restore. When extracting files at last, shows ERROR 1600).

Also when I'm using Pwnage Tool to downgrade also failed.....

Now the situation is the phone only appears iTune logo and white USB cable, with slide for Emergency with Multilanguage, English, French, Deutch, Traditional Chinese etc....with dial panel, and with a Signapore mobile phone sim card inside , but no service appears, and with Locked logo .

Anybody can help me how to do?? thank you so much! shall I need to downgrade to 1.1.1? Also not sure if it work when downgrading,,,,thanks a lots!!!!

Hi. Before to do anything on the iPhone, try to read a lot in advance. Its good to know and understand what you're doing.

Try this to go to 1.1.4:

this thread is horrible with the title.
I'm very tempted to shut it down.
If you took the time to sign up, at least read the guideline and do some searches

What exactly do you want to do?
Stay at 2.0 or downgrade.

The link that duck9000 sent you should get you going on 1.1.4

I'm going to change this title "Anyone can help ?? Thank you!!!" to "[2.0] - I upgrade to fw 2.0, how do I downgrade or unlock it."
