I have iphone 3gs ios 5.1.1 with siri instaled,few month later my iphone always restart or turn off itself,i decide to restore my iphone but always failed with error code 3002,then i trying to upgrade to ios 6.1.2 but i have error again,can somebody help me??Sory for my bad english,
Usually what happens is if it's successful you'll be able to backup the phone and free up space. If it is not successful you'd get a error code usually between -20 to -30 which most of them indicate file system corruption that is unrepairable without a restore . You can also try forcing an update while the phone is in DFU mode. I believe this option is only available in 3utools to do it that way.
as I've said I'm doing a backup when it happened. I saw the backup folder and it was incomplete. I tried the vid tutorial in youtube where you can rename the file format in the backup folder and it didn't work. In my case my backup was encrypted that's why it failed. it's the reason given to me by the youtuber..
due to money issues, I havent been able to get an external hd for my computer for awhile. For the past week my 11 has been sluggish and tonight I finally got a hard drive, emptied my pc out and began doing a backup on my phone. Began doing a bootloop and couldnt get out of it. No way out of it and I finally tried alons suggestion of 3utools, Got errors 3 times and tried itunes again to no avail. Attempted 3u a 4th time and it went completely through and my phone is back to life. I am at this moment doing a full backup of my phone in 3utools. Once thats a success, I am doing the same in itunes again, then making 2 copies of my backups on an sd card lol!!!! Thanks for the bit of help alon!! 2b1af7f3a8
