Troubleshooting iPhone issues
Posted by UCS IT Support 4 on 15 August 2008 12:42 AM
Many users, have had one particularly disastrous major issue with the 2.0.x version of the software.the phone reached a state where it wonâ€™t get past the Apple logo portion of the boot process. This typically happens when applying an update to an application, either via iTunes or on the iPhone itself. During the process, the iPhone will spontaneously reboot, and then get stuck during the boot process, showing just the Apple logo. In one case, I even let it sit at that screen for four hours, just to make sure it was truly stuck.
Unfortunately, if this particular glitch bites you, thereâ€™s absolutely no troubleshooting to be done since you canâ€™t see anything other than the Apple logo. Your only solution at this point is a full restore of the iPhone. Hold down the Home button on the iPhone, plug it into your USB cable or dock, and wait until you see the special screen shown at right, then release the Home button.
The only solution for a logo-stuck iPhone
iTunes will then tell you itâ€™s found a phone in recovery mode, and you can then begin the long process of restoring it. First iTunes will reinstall the latest version of the iPhoneâ€™s operating system, then it will restore your applications (including data youâ€™ve created in those applications) from your last backup, and thenâ€”eventuallyâ€”youâ€™ll be able to sync your music, videos, photos, and other data back to the iPhone.
One interesting aside: if you happen to have new images on the iPhone that youâ€™d like to sync with iPhoto, that may actually work.
An iPhone stuck on booting is, by far, the single most annoying bug in the 2.0 software. we were hoping therecent 2.0.1 updateÂ would solve the problem, but itâ€™s been just as common from me under the new one as with the original 2.0 software.
Troubleshooting other issues
Beyond this fatal injury, however, there are other glitches with phones running iPhone 2.0.x software. Sometimes applications will launch, then quit back to the home screen immediately. Sometimes,Â anyprogram (including those that come pre-installed on the iPhone) will quit on launch. Sometimes, it seems your battery life is disappearing more quickly than gas prices are going up. Iâ€™ve also experienced (and seen reports of other people experiencing) very slow iPhones, wherein every tap on the UI takes a second or two to register.
So what can you do when you have these sorts of troubles with your iPhone (or iPod touch, for that matter)? The short answer is â€œnot very much.â€ Because the system is closed to end-user access, most of the traditional troubleshooting methods donâ€™t applyâ€”thereâ€™s no way to trash a given programâ€™s preferences files, for instance. If one of the iPhoneâ€™s standard programs is crashing, you canâ€™t just reinstall it, because Apple doesnâ€™t provide installers for Mobile Safari, for instance.
The good news, if there can be good news, is that the list of things you can do is very short, so thereâ€™s not a lot of memorization or training required to troubleshoot your iPhone. So without further delay, hereâ€™s a super-short iPhone troubleshooting guide, listing some of the things you can do if youâ€™re having troubles with your iPhone .
