HI guys, just wanted to share how I solved this problem. After I used the latest version of WinPwn (2.0.4) I got the same 1604 error with the subsequent phone locking up. After trying to restore with Itunes I kept getting the same error 6, which means an unknown error, and it simply seemed like I bricked the phone.

Well what really happens is that in this situation you are simply not being able to put your phone in DFU mode. Even when following all instructions on the web you´ll eventually always end up in normal Restore Mode (which is a different thing). So here´s what I did:

Here you can find the complete Pwning guide as well links to download the files:IClarified Guide
Get Ziphone Here

1-Make sure your Itunes is already Pwned and is detecting your Iphone. (for now ignore when it says that it is in restore mode, but leave the phone connected)
2-Download Ziphone, click Advanced Features and select DFU mode (yes, I know... but Ziphone´s DFU option is the easiest method for now)
3-Click on the Output Log you´ll see the program stuck at "Searching for Iphone"
4-Now you have two choices: Simply restart your phone (holding the power button) or try again the manual DFU mode (hold power and home button until screen goes off then release power button but keep holding the home button)
5-Ignore Itunes until Ziphone finds your phone and puts it on DFU mode.
6-If everything went well your phone´s screen should be black and Itunes should detect your phone in Restore Mode (don´t worry, even though it says restore it´s actually DFU)
7-Click Shift+Restore on Itunes and select your custom firmware (the one you created with WinPwn) and let it roll... no more Error 6.

If this doesn´t work, then Uninstall both itunes and winpwn, restart your pc and reinstall both. After that restart this guide. Just don´t forget to do the Itunes Pwning step first (Ipwner option on WinPwn).

That´s it! No need to downgrade your Iphone or Itunes as many people are sugesting. You should be done in less than 30minutes...

Goog Luck!

Thank you for the information....

Like the Step by Step as well

FWIW, using ziphone to put phone in DFU mode is non-sense and not necessary. One of iphone Dev Team member already commented on this (Let me see if I can find the thread).

Do you understand the above statement?
1 - make sure your itunes is pwned means you must click on ipwner (in winpwn) and select the custom firmware you created.

2 - make sure you itunes dectect the phone is not part of the winpwn process. Why are you combining them into one?

6-If everything went well Itunes should detect your phone in Restore Mode (don´t worry, even though it says restore it´s actually DFU)

iTunes says detect phone in restore mode has been like that ever since. The way to tell if you are in DFU mode is the iphone screen should be black (no picture of anything).

Well ... if it worked for you - that's fine but I don't like this method at all.

FWIW, you give me the phone, I can put it in DFU mode or restore mode everytime/anytime. No need for ziphone crap

Wnen you get the 1604 error (or the 6 error) during the restore process you will have a hell of a time putting your phone in DFU mode to restore properly as the phone just keeps reseting to restore mode.

I´ve heard of a lot of people having this problem who know exactely how to put their phones in DFU mode (myself included) and it simply wouldn´t work when in this situation... So yes, I do believe the Ziphone method is for now easier for many people with this problem (even though I don´t like Zibree myself), but thankly a similar method will be included on the next WinPwn release.

As to the "make sure Itunes has detected the Iphone" I know its not part of the pwning process, i´ve included that just to make sure that the person has all drivers setup correctly and that the person has done the Itunes Pwning part of the process. Many times people won´t get the pwning process working simply due to faulty or missing drivers or skipped steps of the process...

In any case, whatever works for you is always the best solution, right?

- thanks for the clarification.
- I guess what ever work for you is fine. One thing is that ziphone DFU thing is only for 1.1.4. I hope people don't take it as a magic tool and try it on 2.0 fw. If I need to use a tool to put 1.1.4 phone in DFU mode, I rather use iLiberty instead.

Personally, I don't want to see people use ziphone at all. Use iLiberty and throw away ziphone.

Actually Ziphone DFU helper does work on 2.x... but you´re right, poeple should stay way from Ziphone as long as they can, as someone is bound to mess up using it...

See how much I know about ziphone - Thanks for you info.
