I have an old version jailkbroken iPhone 16GB Tim with a U.S. sim card, and I was running firmware 1.1.4 and firmware 2.0 is beyond stupid, I decided to try a firmware update 2.0 through iTunes, once I started the process of putting iTunes in recovery mode and soon after was given an error message that a mistake was made … Im now stuck with an iPhone in recovery mode, and I've tried just about his ability to DFU mode and restore the entire firmware 1.0.2 to 1.1.4 of iTunes, but I get the error message persists ass number as (a) (6) (1604) (18) Someone please give me a solution to this dilemma because they have stuck with an old trash Nokia and I paid about 500 euros for the iPhone. People Thank you in advance.

There is a long process of degradation to 1.1.4 2.0 (which needs to relock the iPhone, then upgrade to 2.0, then unlock). If you are interested, please e-mail. The reason you can not because the firmware 2.0 uses a different band (eg upgrading from 1.02 to 1.1.1 only). That's why you can not go directly from 2.0. You will need to erase the baseband. The whole process takes three rolls.
