i am using 1.01 i was on the phone with my sister and the call failed.. i could not call her back or text her or anybody it would give me a message error then i noticed that in the top left corner it doesnt say that im using Tmobile any more although i had a full signal i figured that it needed to re unlocked again so i ran any sim and it gave me a " this phone cannot be unlocked error anysim will now quit" so then i tried to restore it using i tunes all it gives me is a picture of the usb cable pointing to itunes meaning plug up ur phone and start i tunes i tried but nothing happends help plssssss
Restore....go to restore mode (that usb cable pointing the itunes screen)
now connect to itunes...make sure itunes and all its processes are open
now the itunes should detect the phone by itself.....then click shift+restore
use the firmware file you want . click ok. and wait for a while.
If itunes doesn't detect your phone....and you are on 7.5
change to 7.4 and try again
some of this may sound silly...
try closing all itunes processes.....itunes, ituneshelper, etc......and then open the itunes (again)
if it doesnt work restart your PC and open itunes....
also, check if iBrickr detects your phone......if it does, try to boot it
