So honeys, have it rolling on IPhone 4 and hope the next few items collected are helpful:
You made the update and now the the progress stucks between an apple logo and a circle?
*** Keep pressing Power and Home together for around... a while... the apple logo will disappear and it looks like another reboot but comes up with connect to Itunes where it is found in recovery mode.
You have that error 3200 continuesly?
*** Well, that have millions but is getting less and therefore the chances to get through raises, short, apple cannot be contacted while update progress. make a dosbox (run, cmd <enter>) and type ping gs.apple.com and you see ping response times with 150 and more, even had 200 plus... remember how "good" a ping of 200 is while playing online, so you see they are busy.
You have Error 3194?
*** Check you hosts file (like here C:\windows\system32\drivers\etc, hosts, edit with notepad.exe) and check for gs.apple.com, if you have a valid finding set a # to the beginning of the line to make this inactive or remove it when you do not need (its a redirect for cydia, so when you wanr to jailbreak again and the redirected will stay the same keep it inactive, otherwise remove)
You are sick of backup progress before the update that fails anyway?
*** Enter the I4 to DFU Mode so it is found to need a recovery and it skips the backup, but be sure you have made at least one to have your files available to restore back when finished on iOS5.
General:
DFU Mode:
Power Off, Press and keep press Power Button until the Apple Logo has appeared. then keep Power pressed and also press and keep pressed the home button, when the screen turns black count until 5 (seconds) and release the power button but keep home pressed, count until 10 (seconds) and release the home button also, disconnect and reconnect to computer and itunes detects a recovery device.
-> When you keep your phone connected to the computer you have a sound after each step, so it is easier to know when need to press or release a button)
Update File (.ipsw)
is located and downloaded to
XP: %userprofile%\application data\apple computer\itunes\iphone software updates
Vista, 7: %userprofile%\appdata\roaming\apple computer\itunes\iphone software updates
you can copy and paste this to the address bar of your explorer (not your internet explorer, your file explorer... just open "My Computer" or "computer"
)
That's all for the moment thats necessary I guess, if you have troubles keep posting.
Cheers
