I found my device after an Erase i connect it to your computer and restored from a recent backup. It doesn't recognise my carrier

Try contacting your carrier.  Perhaps they need to do something at thier end.

    ipad apps 1 I lost all after I installed new windows and I tried to connect it between your computer and iPad, what's the solution? (Please Inbox : [email protected]) Thanks

    Hi,
    Sounds like it isn't to serious. the Bluetooth connection had an error and that is that generated
    the Problem report.
    When the Blackberry started to use Bluetooth the "gold standard" was using Microsoft's
    "native" windows drivers. Now, every major PC company has there own version
    Thus the problem report.
    There is  rather involved and lengthy procedure to check and install the correct Bluetooth drivers
    in the Dell, but I really don't think you want to take that on.( Nod you head and say H*LL YES)
    Here is what I propose;
    The problem report needs to be resolved or it wont go away. Read the manual, call Dell,
    try apologizing to it and that you'll never never do it again, what ever it takes!
    Make the best investment you can make for your Blackberry, buy a media card.
    All the memory in the BB is dynamic, this facilitates the functions of the phone.
    By storing media in that memory, you effect are wasting X amount for file storage.
    Store all media and files on the media card, and you will have a smooth running device.
    They run about $25.00usd, they are easy to install, and they also make moving your
    media a snap. You will need the USB adapter that came with it, but you can get that at
    your local carrier store.
    So if you agree with this I need some info.
    On the Blackberry go to the options icon,click then scroll up to ABOUT.
    I need your software version number, it's listed in this format: 4.x.x.xxx.
    Send it back to me and I can tell you what size card you can get.
    Let me know your thoughts!

    After restoring my iphone 4 to factory settings, then restoring from a recent backup, my phone will reboot but keeps coming back to the "new setup or restore from backup screen". How can I by-pass this screen to go directly to the sync apps/music screen?

    Well, it's certainly behaving as though the phone that was backed up was synced to a different iTunes library.
    I'm going to throw one more thing out there... Yes, you backed it up to this computer... Was the phone previously set up to sync with this computer? Or was it syncing with a different computer and you just backed it up to this one?
    You may have to end up setting it up as a new device and rebuilding the phone by manually re-syncing your data, apps, music, etc. to the phone.
    Trying to keep your library on a different drive can be tricky. If iTunes starts up and the library isn't available, it may end up generating a new library ID, meaning that you could easily find yourself in exactly the position you're in now...
    I'm curious why there was a need to restore your phone to begin with... It may not have any bearing on this at all, but it could.

  • I'm having a problem with logging into a FileVault-protected user account after restoring from Time Machine backup.

    Hi all,
    My computer had been running really slowly for a while, so I decided to erase the whole hard drive and reinstall the operating system, and then I was going to restore the files I cared about from Time Machine. The main account, which had all my documents and photos, was FileVault-protected. The last thing I did before erasing the hard drive was to run one last Time Machine backup. As far as I remember, I always ran Time Machine backups with the FileVaulted user logged in.
    I don't remember whether I was using FileVault 1 or 2. I had been using FileVault 1, but I installed Lion as soon as it came out and I thought I had migrated to FileVault 2 at that point.
    Once I erased the hard drive and reinstalled the operating system, I browsed the Time Machine disk and, within the Users folder, there was no folder for the main user account. When I tried to reinstall everything by restoring from Time Machine backup, I'd get the option for all the user accounts, but when I tried to log in with the main one I'd get the dreaded "You are unable to log in to the FileVault user account "User" at this time. Log in failed because an error occurred." Finally, when attempting to restore from the Time Machine backup again, I noticed something strange: After the computer got to about 10% done restoring, it declared itself completed successfully and rebooted.
    I've tried a number of tips that came up from questions about similar issues on the Apple support forum, but had no luck. Is there any way to get these files back? Did they ever even get backed up?
    Thanks.

    I can't find it! not sure what's going on but the only folder shown is the " Shared" folder.
    Did you have only the one user account? If there were others, they should also be in the "Users" folder. You probably won't have access to the files inside them, but they should be there.
    From what can make out, it looks like it's not backed up any of the files for the filevault account. Can't see user folder when looking through previous backups in Time Machine galaxy view.
    Are you doing that from a Finder window set to your internal HD, or your computer name? It should look something like this (with the Finder in List view):
    |
    |
    I'd been logging out and backing up manually on a regular basis.
    Scheduled backups should run normally; but they won't back up the File Vault sparse bundle, nor will any run manually.
    The only time it's backed-up is when you actually log out.
    You should have seen this window on logout:
    |
    |
    followed by this one:
    |
    |
    If you didn't see the second one, or cancelled it, the account wasn't backed-up.

  • Imac won't restore from time machine backup after HD (hard drive) recall replacement

    I have an imac bought in 2011, running Snow Leopard.  It required an HD replacement due to the 1 TB Seagate recall - the replacement was done by a certified Apple repair station yesterday.  Before the guy left he started a backup/restore from my latest time machine backup set.  It failed.  I attempted it two times and got error messages that it failed and the computer needed to be restarted to try it again.  No luck.  I called the guy back and he told me to call Apple Care.  Not thrilled about that response since the guy had just left my house I did what he told me to do.  (A quick sideline here:  I recognize that a time machine backup should be no big deal and SHOULD work everytime, but it doesn't.  It irks me that Apple is replacing my HD through no fault of mine and yet they don't allow the restore of data to be a "covered" expense in this process - this isn't just because this was an authorized repair guy - the Apple store would have done the same). 
    Back to the issue.  When I called apple care they pretty much had me try the same thing again with an earlier back up set.  To my knowledge, it didn't work.  I say this because it looked like it was working and when I came back to the imac later, it had restarted and once again booted to the OSX install.  (The boot disc is still in the imac).  When I tried to boot from another location, one did not show up to boot from so I assumed that the data didn't transfer and it forced another restart.  So, I tried something else.  I tried to re-install the snow leopard OSX without using the restore function.  That appeared to work and then when the machine restarted it asked if I had another mac and I chose the option to get the files/apps/etc. from my time machine backup.  The computer chose what I can only assume is the most recent backup set (It chose what I know to be a subfolder that appears under the dated backup folder - Macintosh HD--which btw is confusing seeing as that's always the name of the HD on the imac).  I again stepped away from the computer so it could do its thing for two hours.  When I returned, I was back to the MAC OSX screen that asks you to choose a language.  There were no more options to choose DISK UTILITY or RESTORE FROM BACKUP, etc.  When I clicked on English it took me right back into the screen where you say whether you have another Apple that you want to transfer data from.  I realized that the imac must have restarted and I assumed maybe it was because the boot disk was still in - except how do you get the disc to eject?  I also initially assumed that the backup had somehow failed again and triggered a restart.  I tried to choose the option to just set up the machine without transferring data and when I got to the choose a name for your HOME folder message I tried to enter the same name I had it as before and it wouldn't allow me to do so, saying that that name was already in use.  I also tried a different name and that didn't work either - got the same message (I assume if it is not the same name that it won't sync up with the time machine data from the backup set).  So, I almost tried the "select time machine backup" option again until I looked at my HD space.  Clearly, there is space that has been used.  HD space was 997 at the start and now it's 636. My initial thought is to somehow get back into the setup area where I can use disc utility and erase the whole thing and then start over but 1) I don't think it's going to work even if I could get back there 2) I have no idea how to get this thing to reboot into that mode 3) I can't get the boot CD out to even try to restart to see if this thing did what it was supposed to, SO NOW I AM TOTALLY STUCK!  I have not called Apple Care back because quite frankly they were useless the first time.  I have a call into the repair guy but who knows how much help he will be.  In the mean time, I have a million things to do and a computer that isn't working - Whoever said Apples never have issues needs to be seriously censored!
    A few other notes:  I use Time Machine Editor to run my backups weekly.  It was set up that way from the get go by an Apple rep who came to my house to get us up and running.  Editor should not effect the way that time machine does its work, so I doubt there is relevance but thought it worth mentioning. 
    One other note is that the Apple Care agent tried to have me do something called a "Source" something or other from the disk utility screen but when she realized that my backup file (shown by date) contained many other sub files (11-27-12/MacintoshHD/MyNamesIMAC/etc.), it was not possible to run this operation - thus we aborted.  Sorry I don't remember the name of the process and unfortunately now can't access that option to go find it. 
    If you can help me, I would be eternally grateful!  I am open to having a phone conversation if you are willing to give me your email to mail you my number. I have so much work to do this week and this was the last thing I needed.  Did I mention this was supposed to be EASY?
    I used to be quite the geek with my PC - still on the learning curve with the mac but not enjoying it.  I am fairly tech savvy and I can follow instructions for a step by step solution if you've got one. 

    I got a recall and had the drive replaced. I have retored 3 timesa dn even had apple do the job and it is still not right. I still can't get a simple ghost of the data from time machineback tot he new drive. 
    This is Apple's explaination as taken from their web page.:
    Restoring your entire system from a backup
    If you are restoring a backup made by a Mac to the same Mac
    With your backup drive connected, start up your Mac from the Recovery system (Command-R at startup) or Mac OS X v10.6 installation disc. Then use the "Restore From Time Machine Backup" utility.
    Note: If "You can't restore   this backup because it was created by a different model of Mac" appears  when restoring  a backup that was  made on a different Mac, follow the onscreen instructions.
    I even posted this information on the community and apple removed it... because they don't like the:
    Off-topic or non-technical posts
    Non-constructive rants or complaints
    But here is my experieince:
    Take in 27iMac running 10.6.8, 5-7 days, what a joke, my boss will be happy to pay for a week without working. Finally get, "if you have TM back up, 3 days." Get machine back with 10.6.3, hit the R recovery, click TM back up, runs for 2 hours, reboots, looks great. Box up take back to office... update to install - OH NO, still running 10.6.3. Updates crash with no specific error on install, BUG PROBELM, nothing runs.
    Call Apple... after hours, tells me to boot using 10.6.2 disk, wipe, reinstall OS, udate to 10.6.8, THEN do the restore. GREAT! Only thing 10.6.2 DVD won't read... now back on phone... take back to the store, Genius says, he'll ix it just like it was. PROMISES it'll be fixed.
    Pick up next day, supposedly, booted to disk, wiped drive, reinstalled, updated to 10.6.8 and THEN did the RIGHT restore... Looks GREAT... apps run and 10.6.8 OS. Back to the office... NOT RUNNING right!!!... fonts messed up, drop box app needs new install, cocktail needs upgrade, Fetch not working, memorized paths gone... back ups locked out of permissions... ***!!
    4 hours on phone with apple and still no rsolution - to missing "settings". Seems there are THREE WAYS TO RESTORE (according to apply tech)... Running MIGRATE ASSISTANT and being able to choose your files, including settings, "R" RESTORE after they load a new OS... or NOW WAITING for them to send me a bootable 10.6.3 disk and then boot from disk, w/o installing OS and doing a restore from TM. I think this is done via the disk Utilties application.
    So now can't back up without doing a full 400 GB back up since permissons are screwed and possibly destroying any good back ups... can't work, like having hands tied behind back. WAITING for solution! Very upset!!!
    I did my first restore just like they said and now an 10 days without proper machine. Just FYI. I thnk I am going to make the store do the tech work so I have somthing to fall back on.

    After re-installing Win 7 64 on my computer, and attempting to install my copy of Adobe Photoshop Elements, I now get the following message: "This version of Photoshop Elements requires MS Internet Explorer 4.0 or higher to be installed". Does anyone have an idea of what the problem is? It has always worked in the past.

    I have found a temporary solution, allowing the previous version of iTunes (v. 11.1.3 (x64) in my case) to be re-installed.  It will allow you to re-establish use of iTunes until the Apple software engineers fix the most recent disasterous upgrade (v. 11.1.4).  Please see and follow the procedure in the following article:http://smallbusiness.chron.com/reverting-previous-version-itunes-32590.html   The previous version works beautifully.

  • I live in Canada.  Each time I travel to the US, I lose all calendar entries.  I have to erase all data, then restore from an iCloud backup.  Tedious.  iPhone 4, iOS 7.1, sync set to all events.  Any suggestions?

    I live in Canada.  Each time I travel to the US, I lose all calendar entries.  I have to erase all data, then restore from an iCloud backup.  Tedious.  iPhone 4, iOS 7.1, sync set to all events.  I only use the default calendar.  Do I have an incorrect setting?

    I did find another point worth mentioning. 
    I use my iPhone 4 with a corporate Exchange email account.  I had deleted the account from my phone just before I did this backup/restore process...and I thought my battery drain was much, much better (if not outright fixed). 
    Later in the day, after seeing my battery life improve to near-new behavior, I re-added my Exchange mail account.  Considering I have 1 yahoo account and 3 gmail accounts, the Exchange account adds a 5th email account.
    What happened?  Battery drain back to "worst case".  Removing or re-adding the Exchange account is like toggling between decent and terrible drain conditions.
    Bottom line is that I re-added a couple dozen applications and battery life didn't change.  By far, the Exchange account drains the battery worse than any other app and setting.  This account must be polling very frequently and since people tend to send very large file attachments to that account, perhaps those effect the battery drain even though I have the account set to not download attachments.
    Anyone running Microsoft Exchange might be able to confirm what I see?  If so I can open an enterprise ticket with Microsoft and bug them on this issue.

  • I was using my ipad it was under 10% but no under 4% it turned off then i pluged the charger in and flashed on then showed apple sign after i turned it on. now its going back and forth from the apple sign and battery symbol ive changed chargers its not on

    hey please help!
    i was using my ipad it was under 10% but no under 4% it turned off then i pluged the charger in and flashed on then showed apple sign after i turned it on. now its going back and forth from the apple sign and battery symbol ive changed chargers its made no differnce its been like 3 hours ive tried to do that reset thing holding lock button and home button for 10 seconds at the same time. WHAT DO I DO?

    Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
    Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • TS3992 My iPad hasn't backed up to iCloud for 2 weeks so I've connected it to my laptop and it still won't backup and this is AFTER I paid for extra iCloud storage. I'm so frustrated because it keeps saying back-up failed but I don't know why.

    My iPad hasn't backed up to iCloud for 2 weeks after repeated attempts even AFTER I paid extra for more iCloud storage. I've connected it to my laptop and it still won't backup. I'm so frustrated because it keeps saying back-up failed but I don't know why. Please help, thanks!

    To back up to your computer, right-click on the name of your iPad on the left side of iTunes and click Back Up.  (If running iTunes 11, first go to View>Show Sidebar.)
    To get your iPad to back up to iCloud again, try deleting your last backup (if you have one) by turning off iCloud Backup in Settings>iCloud>Storage & Backup, then tap Manage Storage, swipe across your backup and tap Delete, then go back and turn iCloud Backup back on again.  If it still won't back up, you may have an app that is preventing the backup from succeeding.  To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again.  If it succeeds, then the camera roll and/or one of your apps is preventing the backup and you'll have to located by process of elimination. Turn the camera roll On and try backing up again.  If it succeeds, turn some of your apps to On and try backing up again.  If it succeeds again, turn some more apps to On then try again; repeat this process until it fails.  Eventually you'll be able to locate the problem app and exclude it from your backup.
    If it still won't back up you may have network issues connecting to the iCloud server.  Solutions to that include power-cycling your wireless router (unplugging it for 15 seconds, then plugging it back in), resetting network settings on your phone (in Settings>General>Reset), updating the firmware on your router, and changing the router's DNS settings to use Google's public DNS (see https://developers.google.com/speed/public-dns/docs/using).

  • Malicious or not? Message popped up: Mozilla security found (something like too much, forget exact word) activity on your computer so it will do a fast scan of system file. With OK button.

    I was looking at youtube.com, which always tells me my browser is not supported and recommends I download Firefox, but that is what I was using, so I went to Firefox to check for updates. (I think I also had freecycle.org open.) Then this message popped up in a new page: Mozilla security found (something like "too much", forget exact word) activity on your computer so it will do a fast scan of system file. There was an OK button. The page address was: http://update17.stegner.ce.ms/index.php?Q7Lhl9ShbRxGJXpkM1VLSi4ZE8H4pTedoVPySgeppM3VpC+thEspcFG7qxHgn1pdsC2h5ygPGWI3t5hXqMzL9EQaZZ3J1e3CKXgCb0Qp. I did not click OK but copied the link and closed the window which closed the internet. I have never seen this before and would like to know if it is really Mozilla or possibly something malicious. Thank you.

    Good catch. That almost certainly is an invitation to download malware.
    There are a lot of infected web sites pushing "fake antivirus" software. If you have any doubts about whether your system might have become infected, you can supplement your regular security software with these two highly regarded scanners:

  • HT1414 I'm trying to restore from an earlier backup but my iphone only shows the most recent. I'm on Windows Vista and found the backup folder. If I delete the recent files, will it force the iPhone to backup from the next older file?  Why doesn't it show

    I'm trying to recover a file and the app company said to restore from an earlier backup.  My iPhone only shows the most recent backup.  I've been searching the net for answers - I found the back up file and date sorted them (over 6mb of files).  How can I get my iPhone to restore from an earlier backup? 
    I am on Windows Vista so I don't have Time Machine. 
    I have backed up the backup folder so if I mess it up, I have it in a separate place.
    Can I just delete all the files with todays date in that backup folder and have it forced to the next oldest date?
    Why doesn't the iPhone show a list of the least several backups.
    Info:
    iPhone 4S
    Software version  5.1.1
    Backed up to computer through iTunes (not iCloud)

    As you backup the iPhone in iTunes, it overwrites the last backup. Files are kept as they are changed, so that would explain how you get different dates in your backup folder. The only backups that are saved and not overwritten are the ones done just prior to a restore. You do have the option to go back in time on a Windows computer, however depending on the last time you set a restore point in Windows, it could be back further than you are willing to go.
