Ahh..... I remember it so well, I had the same problem. Do not do a full reset because it screws up your phone, the reset to factory is for iphone that is not JB or unlock before hence you and I had that problem. I would suggest that you do Winpwn it back to FW 2.01 first by using this guide.

http://sleepers.net/news/2008/07/25/winpwn-20-guide/

Read the section on how to DFU, there are suppose to be 3 way so of DFU depending on the batches of iphone. For me I did this.

1. Attach the phone to the pc
2. Turn the phone off
3. Press and hold power. Keep holding power. As soon as you see display on the screen of any sort press and hold home.
4. Hold power and home together for *exactly* 10 seconds
5. Release power but keep holding home until the pc beeps as a USB device is recognized.

When the PC beep then the screen on the iphone would blank out and I think it would flash white once.
And if you had followed the guide then your itune 7.7 would be PWN and you should be ready to shift restore to restore back to FW 2.01.

Now KISS YOUR IPHONE and SCREAM

Go search for a guide on how to upgrade to FW 2.1, I use the easy way by download a JB version of 2.1 and restore. It works for me.

Hope this help.

Haha, thanks jackdon. I also suspected a same thing, but it not happen during my iPhone 2G 8Gb (FW 1.1.4).


Anyway one funny thing, my PC cannot detect my iPhone but it can detected by Mac. So now i started downloading the necessary file to JB again the iPhone but this time using Mac..

so maybe this midnight i'll start JB the iPhone..

Will let know if anything happen..

lol, u found my post.
very good
cause my iphone still suffering from it
still can't fix it

Are you sure it is not your PC USB fault, the MAC is also detecting the iphone using the USB.

jackdon.

i still can't restore mine. doesn't matter if its normal or custom.
still stuck with error 1604 and 1603
really dunno what to do. tried everything. still cannot. tried on new PCs that have never touched iphones also still cannot

yeah this shud work..

Two days without iPhone is boring.......

what are u using?winpawn?quickpawn?

whatever i do also cannot
using pwnagetool create custom firware and restore also cannot
hard reset also cannot
normal restore to 2.1 firmware also cannot..
DFU mode also cannot.
guess i'll be at the TT.. haha

Guess my problem also same as you .........Done most evrything already...

Did you try all 3 method of DFU ?

jackdon

You are right !!! Finally my iPhone is back to normal with 2.1 FW at 8Pm today after 2 days of trying

The key of the success is to press the correct DFU method.....



Anyway Thanks to everyone who contributed to settle this problem

i guess so.. since davvycroix silently silent? hahahahahaa

how long does it take for quickpwn to jailbreak the iphone, i'm not sure whether my iphone froze or it's being jailbreakon. It says in Quickpwn, Uploading exploit bootloader and the iphone screen is white but after all it seems that the iphone screen turns back to nothing as in black and then it's wait wait. How ah ?

Hi ! I'm TS for this thread. I suprised this thread is re-open again and for info, my iPhone working great. Anyway this mid of October thread.
