My iPhone 3Gs 32gb keeps rebooting every 5 - 10 minutes after upgrading to the final version of ios5 that was released.  When I try "restore" from itunes (when I am able to keep the phone on long enough that is) I get an error (1645).


Thank you in advance for any help, my iphone is pretty much useless until this is resolved!

iPhone 3GS, iOS 5

I just ereased all my contents and settings since nothing else seemed to work.  It's fixed now but I have a feeling it might be an app that is making it crash so I'm not sure what i'm going to do about that considering I have no idea which one.

    Same thing happened to me.. I HATE IPHONE. From the first day, they always rushed launching out new stuff w/o having enough stability tests.. Yet, thousands of people suffer at your iphones.. I know you are doing great things but YOUR PRODUCT CIRCLE IS NOT COMPLETE THIS WAY. No matter what, I'll give a chance to your competators and quit iphone asap!

    I am having the same issue, and it got worsen with the 5.0.1 update today.. It just keep restarting itself every 2 minutes! What's wrong with iOS5..

  • Davo1122 Level 1 Level 1

    Yeah, same issue here, this *****, glad I'm out of contract. I will simply move to Samsung (the iphone that works...... hey they make most of the parts! )

    Found you cannot formally notify apple of any of these issues, unless you want to PAY them for messing up your iphone with mandatory updates, of course.

    Rather than rebuild, I've found it easier just to reset it (home and off key) wait a little while - 10 minutes? (if you do not it simply resumes whatever process is HUNG) . Then turn it back on, stupid thing comes back and smiles at you as if nothing happend.. Grrrrr.


    Looking on ebay web shops now for a galaxy II.


    Interesting, I let it alone once (I get an apple logo), with the charger plugged in, I checked it an hour later and it was HOT, its stuck in a processor loop/deadly embrace. They're obviously still having trouble with multiprocessing. Silly of me to expect a Apple to be able to do something minix was doing 10 years ago heheheheh, go back to your iPODS apple, at least theres not much to mess up with that one. (anyone remember the iRiver, Iwonder?)

    MMM of interest, just read a newspaper report about iphones bursting into flames on a flight - will IOS5 kill someone do you think? That would be something for the IEEE minutes, I can see it now, "Phone software bug takes down plane"!!!

  • CMY77 Level 1 Level 1

    so i had to restore my iphone (follow my previous post). while restoring, i removed many of the apps I'm not using. From then on, i have no problem of anything. Of course, i didn't update to 5.01 -> NO WAY. I hope iphone's software milestones will be something like windows 7.. they had us pull our hairs A LOT, but with windows 7, life became more fun to live.

  • Davo1122 Level 1 Level 1

    No, see above, already did a restore. The phone just goes into a naval gaze and gets reeeeeeaaallllly hot.

    I will sue apple if it burns my house down overnight. This kind of bug is going to kill someone

    Mark my words....

  • CMY77 Level 1 Level 1

    Only restoring is not enough my friend. Uninstall all the apps you are not using also.

    give it a try ; )

    P.S. my first comment is still valid. Fact is a fact..

  • Davo1122 Level 1 Level 1

    ***Sigh*** whateva, see above, I restored, IOS5 restore removes all apps on my phone, so, yes, it has been professionally cleaned by the helpful crew at apple IOS industries. Twice.


    Further, this fault is not mine alone, I spoke with a Iphone 4 user, same deal, freezes, restarts, don't know how apple are managing to keep this out of the news.... Must take a lot of clout, maybe the editors are all fanboys, or still on IOS 4

    Hi all,


    I'm not sure but I hope this might be helpful to some of you who are having the same problem as I was having. My iPhone (3GS) was restarting frequently after I have upgraded that to iOS 5. I noticed that the problem of restarting happens when the network is enabled. So I suggest trying to enable the airplane mode and see if the phone still restarts.


    When i enabled the airplane mode, the phone was pretty much stable and didn't have any problem. So I've tried disabling the airplane more and disabled the network. I've tried connecting to WiFi network and it was still working fine. So I figured, the problem must be with the network.


    The thing I have found and I'm not sure if it might be the same case with you all, is that perhaps the iPhone was trying to get a data network connection and since I didn't have any at that time, it failed and for some reasons it restarted. When I switched on the data connection under the network, the phone was stable again without any problems.


    Maybe you want to go through the same process and pin point the problem. I hope this may be helpful to some of you having the same problem as I had.

    I've forgot to mention that I've tried restoring to a fresh copy of iOS and that didn't help too. So like I said, in my case, the problem was, strangely, the network data connection. Once it was turned on, the phone was as smooth and stable as it was before.

    No sim card or airplane mode no crashes. I have tried with 3G on and off, wifi on/off backround data on and off Nothing seems to help, My phone crashes less since I turned off spotlight but If I use any app after say 2 mins it reboots


    I have restored from DFU mode and it's never had dodgy IOS on it or anything like that grrrrr
