  • Phone not working after the software upgrade

    I performed the software upgrade as indicated by the phone in the notifications.
    One the phone rebooted, I proceeded to enter my email accounts and it froze on a white screen with a spinning wheel.
    I rebooted and it continued to freeze.
    I took the battery out, rebooted, still can't add email accounts.  It freezes in the setting section.  I actually can't change any settings.
    If I reply to a text, the screen freezes black.
    If I try to reply to an email, the screen says, "Could not display this message"
    I have wiped it three times, powered off a billion times and still keeps freezing.  The update has been nothing but grief. 
    Any advice??

I've downloaded the software and waiting for quite some time and after the dowloading has completed, the file will be processed. After processing, there is a popup saying that somehow the software upgrade failed and said something like make sure that your connection is correct etc. Do you have any idea on how to solve this issue?

  • Since the software upgrade connecting to hotspot from my iphone with my ipad is not working.

    Since the software upgrade , I cannot connect my ipad2 to my iphone 4s via the phones hotspot.  Regular wifi is ok.  Is anyone else having this problem?  I tried resetting the network settings on the ipad, but it didn't help.  The ipad sees the hotspot, but doesn't connect.  My phone service is with Verizon.

    I think I solved the problem.  I did a network reset on both the ipad and iphone.  So far so good.

    I did a software upgrade to IOS6 and my Iphone4S is now unable to update. Do I lose all my contacts and calendar entries when I restore?

    You should be syncing all your contacts and calendars with your computer, either via iCloud or iTunes, so it is easy to re-sync them back to the phone after you restore.

  • IPod Touch skips, stutters, glitches through songs since software upgrade!

    Hi everyone,
    *Since I upgraded my iPod Touch* to the latest available software update +(for the 1st Gen is 3.1.3)+, it has become *unable to properly play any music encoded above 128kbps*. Before the upgrade, my iPod could play music encoded in any higher bitrates like a champ! All the way to 320kbps, variable, even Apple Lossless format used to play flawlessly.
    Suddenly after the last *firmware update*, most of the songs in my iPod Touch would *skip, glitch and garble, making electronic glitches and annoying noises* for no apparent reason. On occasion, the iPod would even *add several second of silence in the middle of random songs*. It's bizarre!
    It definitely took me a while to figure it out, and spent weeks testing and researching what could be the problem. It was truly driving me nuts! The result of all these tests was clear: the *iPod Touch now CHOKES on any music file encoded higher than 128 kbps ACC*. Truly pathetic for such an expensive little jukebox. Even the early MP3 players I owned 10 years ago were able to play variable rate MP3 files without a glitch. *_This is a major bug that needs to be solved_*.
    For those interested, I did the following tests through my weeks of research to find out the culprit to this problem:
    - - - Reinstalled the device software
    - - - Reformatted the device, then updated the software
    - - - Uninstalled all apps, reinstalled and tested my music after reinstalling each app
    - - - Disabled Wi-Fi (no difference)
    - - - Copied over my music library from scratch, several times (it was painful)
    - - - Reformatted a few albums in different bitrates, from 96kbps, all the way to 320kbps, both in constant and variable rates, and tested them one by one. This took days.
    In the end, there is one thing that was consistently clear: *any songs encoded over 128kbps would skip, glitch and sound corrupted. Time after time*. All those music files I had encoded at higher rates +(192 kbps, variable 240 kbps and beyond)+ would make the iPod choke.
    There is one temporary solution to this mess, but it involves reducing the quality of your music files: The only way I can now play my music collection in my iPod Touch without skips and glitches is by downconverting my files to the now *obsolete 128kbps*. Only when I converted my music to 128kbps, the annoying skips and glitches stopped. For an audiophile like myself, this was an absolutely painful decision, as I can tell the *obvious loss in quality and nuance in my music files since i had to downconvert them*.
    Funny: this skipping problem *also affects any files purchased from iTunes* +(encoded at 240 kbps variable rate)+. Should I ask for my money back, Apple?
    I find this irritating and painful, since *the ONE THING the iPod is supposed to do well* (aside from apps, games, and web browsing) *is to PLAY AUDIO AND MUSIC FILES*.
    I spent a lot of money on this machine, and until recently it worked like magic; I just wished it played music again like it's supposed to. It's what the iPod was built to do. *Apple: Please fix the software!*
    I wonder if there's a forum where I could post my detailed findings, so Apple engineers can take note of this *MAJOR BUG*.
    PS: I have recently learned this is a very common bug, and tons of people are reaching out telling me they are experiencing the same annoying problems. Furthermore, *this seems to affect not just the 1st Gen, but ALL generations of the iPod Touch*. It's a *widespread software issue* that was not properly addressed in the latest software upgrade. I'm starting to worry about Apple's quality assurance process.

    Hi everyone. Thanks to a tip in another forum, I think I had a breakthrough regarding this problem. I have the strong suspicion it's not the software for the iPod Touch, but instead, the problem comes from *iTunes and how it handles USB 2.0 transfers*.
    To make a long story short, all your *music that's encoded above 128 kbps gets corrupted when you transfer it to your Touch from iTunes through your USB 2.0 connection*. That's where the problem is!
    I performed this simple test:
    *PART 1 - WIFI*
    - I connected my iPod Touch via Wi-Fi to the iTunes Store. Bought an album encoded at a very high bitrate (Coldplay's "Viva la Vida", encoded at 256KBPS).
    - Downloaded the Coldplay album directly to my iPod Touch via Wi-Fi.
    - Tested every song in the album, and they all played flawlessly.
    *PART 2 - USB 2.0*
    - Now, I erased the Coldplay album from my iPod Touch.
    - Connected my iPod Touch to my computer, and downloaded the album again via iTunes. I copied the very same album to my iPod Touch, this time using the USB 2.0 connection.
    - I tested every song in the album. Guess what: most of them are corrupted, skipping, glitching, making garbled noises.
    I think a reached a minor "eureka" moment. *It's not the iPod Touch software: It's iTunes, and how iTunes deals with your USB 2.0 connection*.
    Now, I'm not an engineer, and I don't know how to fix this problem. I wonder if there's anyone out there there that knows why high bitrate files get corrupted during the file transfer. Hope anyone can shed some additional light on this issue, so we can find a solution.

  • Ipod no longer works in car after software upgrade

    After doing the most recent software upgrade on my ipod touch, the device is no longer recognised when i cnnect it to my car stereo (infinity). How can i uninstall the last upgrade??

    Downgrading the iOS is not supported by Apple.
    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    However, sometime the iOS update breaks compatibility and yo have to wait for either an iOS update or a firmware update for your car system.

    As I downloaded new software upgrade in my iPod nano 7 th gen and also new iTunes upgrade then all data on my iPod got erased and now when I am trying to sync it again then sync button is disabled on the windows screen . Kindly help

    From the OP: "My old computer got a virus and when that happened all my music was lost. "
    They don't have the music on their computer so they cannot transfer the iTunes folder, from the computer to their iPod and then to the new computer. And if they try to enable disk use on the iPod it will erase all the music that is on it. The method you cited is moving the files in a data format using the iPod as a flash drive. It doesn't work if they are in music format. That is why I suggested Yamipod.

  • Ipod touch 2.1 software upgrade problem

    Hi so i have a first generation ipod touch and i have bought the 2.1 software upgrade but now it is saying that in order to upgrade i have to wipe all content currently on my ipod.
    This is a problem because I do not have all the files that are on my ipod on my computer, so if i upgrade then i will lose most of my music and videos, but i do not want to waste my money because i paid $13 for the upgrade.
    Is it possible to upgrade my ipod without erasing my content?
    any help would be much appreciated!
    Thanks in advance

    not from about from 1.x to 2.x but mine came with 2.0.0 and i used all upgrades untill this 2.1 and i only sync'd my ipod touch 1 time
    the rest of the times it does a restore and upgrade and restore the restore
    if it's different from 1.x to 2.x then there
    are programs you can manualy copy out your media before the upgrade
    try using search or google as i dont know their names

  • HT1338 I have an HP Printer/scanner, and since upgrading to Mountain Lion I can no longer scan on my HP.  HP tells me that I can get an upgrade app from 'Apple Software Upgrade' .  Does anyone know how to do this?

    I have an HP Printer/scanner, and since upgrading to Mountain Lion I can no longer scan on my HP.  HP tells me that I can get an upgrade app from 'Apple Software Upgrade' .  Does anyone know how to do this?

    HP couldn't find its own apps with both hands and a flashlight.
    As of Lion all scanning functions are incorporated natively in OS X. You can scan three ways:
    Use Preview: File > Import from scanner
    Use Image Capture
    (Preview and Image Capture are both in your Applications folder.)
    System Preferences > Print & Scan. Select your HP and use the Scan tab.
    If you have HP's "Image Zone" software installed, you no longer need it and it no longer works anyway.

  • IPhone 2.0 firmware for iPod Touch with Software Upgrade

    Okay, don't get me wrong... I don't think Apple should always give everything away for free. But since I already spent my precious $20 back in January for the Software Upgrade, I should DEFINITELY get the $10 2.0 FW update for free since it INCLUDES the software I already purchased! Apple... ya listening??!!??

    i COMPLETELY agree with you. i mean the math alone reveals the nonsense. i will be spending approx. $30 for the two upgrades, while plenty of people will be getting the EXACT same package for only $10! it's almost like we're being punished for purchasing early. what gives?

    I lost all my data while doing the latest software upgrade, how do I get it back if I dont have a backup on iTunes?

    If you don't have a backup, then all your pics/text/notes are gone.
    You can sync back music and app.  If you were syncing your contacts with a program in itunes, then you'll get that back.
    Not sure why you didn't do a backup, especially prior to doing an upgrade.

    Try repairing permissions. My favorite way is with a utility called AppleJack. Info and download here. It's free. It only works when you boot in Single User Mode. When restarting or booting, hold down the Command key and S keys.
    You will get a very different startup screen that looks like the Terminal app has hijacked the screen. Just let the lines of text scroll by. When that happens you will get a text entry prompt. Type in "AppleJack" without the quotation marks.
    A DOS looking menu will appear. Choose 1 or d to run Disk Repair. If you get a message that Disk Repair found and corrected errors, run it again. Repeat until you get the "your disk appears to be ok" message. This rarely happens with my experience, though. This does the same thing as as booting from an external drive and running Disk Utility's repair. Only, no external drive is required!
    Next, choose 2 or p to repair disk permissions. This will take a little while. AppleJack warns that it will take up to an half hour to run repair permissions. It'n never taken more than about ten minutes for my MacBook Pro.
    As permissions are repaired, you will see each repair scroll on the screen. When done, the menu returns, choose q to quit. Then at the prompt, enter "exit" without the quotes. Your MacBook Pro should restart into Mac OS normally after this.
    Hope this helps.
