well I have a jailbroken, winpwn iphone. And now I can't restore it, if I plugged up my iPhone to my computer , iTunes will not
recognize it. But if I put it in the recovery mode iTunes
will recognize it. But when I hit restore, it goes through
the steps until it gets to preparing for restore. And then displays
an error of 1604 or 1603? What's up!!!!
but it works now except for safari will not hold on to it's
history, that's why I tried to restore it.
Have you tried putting it in DFU mode, restoring from there, and then using ziphone to boot the phone? That combo should work.
Also,
if your using winpwn, make sure your boot logo isn't too large, that can cause those errors as well.
