No signal after you have unlocked the new iPhone 4S

Just got my brand new (sealed box) Vodafone 4S managed to unlock via iTunes, put my existing (of work) O2 Sim in and waited for 24 hours to see that I have NO signal. 3G (internet) and everything works fine but impossible to send or receive calls, messages, etc. Have tried every conceivable reset and restore anything will do. Were informed by O2 customer service that the issue is now with the phone... So, what the * is happening and how to fix this?

There is no such thing as a 'new' iPhone 4S. He was suspended for years.

If you think This is new, check the warranty here: https://www.apple.com/legal/warranty/?cid=acs:applesearch

If it is defective, have it replaced.

  • Windows 7 no sound after you have unlocked the PC

    I have Windows 7 Professional SP 1, running on a ThinkPad: Lenovo's laptop.  No matter when I manually lock the PC (with Windows + L) or the screen saver times out and locks the PC, after you have unlocked the PC no sounds work, at all.  I checked device - nothing wrong with that Manager.  I checked my drivers - all to date.  There is no update in Windows Update.  I ran the audio troubleshooting integrated: he can't find anything wrong.  In the Volume mixer, I see even the green bar pulses up and down with the intensity of sound is supposed to be played - except that I can't hear anything no matter what.  I tried inhibition and reactivate the speaker control.  The only thing that 'fixed' it is logging and back, which of course is a pain.  Can anyone think how this can be fixed?  Thank you.

    Hello

    For me, it looks like a driver problem.

    I know that you have checked for drivers on windows update and they are up to date. However I suggest to uninstall the audio drivers from the Manager of devices and then re - install on the manufacturer's Web site and see if that helps.

    Let us try the following steps:

    (a) click Start, type Device Manager and hit enter.

    (b) expand sound, video and game controllers.

    (c) make a right click on the audio adapter Conexant and click on uninstall.

    (d) computer.

    (e) log on to the site of the manufacturer (Conexant) audio adapter, download and install the latest drivers and install them.

    Please let us know if you need more help with this, or everything related to Microsoft Windows.

    Link to your thread to listen would have helped: Oracle XE 11g with Apex No problem of Listener (ORA-12541: listener TNS:no)

    It seems that your listener uses the static instance via the listener.ora file registration and missing entries for the http service. Edit your listener.ora (F:\Apex_Installed\app\oracle\product\11.2.0\server\network\ADMIN\listener.ora) file and add the following entries in the listener.ora file DESCRIPTION_LIST. Then, restart the listenerer.

  • After you have installed the new cartridge HP do not print black ink

    HP Officejet 4620, Windows 7... installed new HP black ink cartridge and now it will not print black at all. I followed all the advice line in the help section, even cleaned the vents on the cartridge itself but shows only the white page. No error message is displayed. Diagnostic ran and says it all works correctly. Also cleaned printheads through 2 cycles still nothing. Any other suggestions? It was working fine before inserting the new black ink cartridge.

    Hi Teresa1960,

    Welcome to the Forums of HP Support! I see that you are facing some print quality problems on your HP Officejet 4620 you cannot print in black ink.

    You have completed all THE steps listed here: printer does not print black ink or color of ink or prints blank Pages, without success.

    Please note: there are three stages of print head cleaning. Three steps if necessary. If the print head is badly clogged, it may require another round of cleaning. If so, wait 30 minutes after the last step of cleaning (third) to start the first stage of the cleanup process.

    If you are unable to print in black ink, I think that the issue may be the printer and not the cartridge. I highly recommend call you our technical support at the 800-474-6836, I'm sure they will be able to help you regardless of the status of the guarantee.

  • Partition Windows 10 does not start after you have created the new internal drive

    I'm running OS X 10.11.2.

    I have set up a training camp 10 Windows on my Macbook Pro sometime ago, but today I realized that I need more storage. I watched how do so online and came across this thread:How to resize my bootcamp partition without deleting chtol. I followed the instructions, but could not know how do I find my Windows partition.

    So I think that I have the problem described here: repair Boot Camp after having created the new partition. I did what Christopher Murphy described on the first page and this error message appeared when I pressed "w ":

    "Failed to open device ' / dev/disk0 ' for writing! Errno is 1! Writing of abandonment! »

    I deleted from the extra without internal hard drive name in the hope that he'll fix it, but it didn't.

    I would like to enlarge my Windows partition, but at this point, as long as I can access my Windows Bootcamp partition, that would be great!

    EDIT: I unfortunately do not back to the time Machine.

    Resizing Windows partitions is not officially supported by Apple - Boot Camp: resize the Windows partition .

  • Tecra M5-388: touchpad question after you have connected the new adapter

    Hello

    I have recently brought a new adapter to replace my old on my Tecra M5-388 by ebay, it has the Toshiba logo on it and safety symbols and plug in my mouse immediately after began to falter on the point that I rely on and the touch pad has become rather not consistent; Disconnect the power supply and it goes back to normal.

    The thing is that the former adapter was a clover sheet plug in brick, even if this new is a figure 8.
    Does anyone know if the maps are specific to each model?
    I'm a little worried that too much current is running through the laptop.

    Any help would be great.

  • Queue after you have reinstalled the new MacBook Pro will not start SOUL

    MacBookPro, 2.8 GHZ Intel Core i7, 16 GB of RAM

    OSX 10.9.4

    CC 2014

    Hi, I used Migration Assistant to copy the data from my old machine to a new MacBookPro. At the launch of CC for the first time there was a lot of error messages, so I uninstalled all my Apps CC and began to resettle. PP and AE work perfectly but the SOUL doesn't "start queue" and hangs on exit. I tried different codecs. I tried to uninstall and reinstall SOUL. Short of a clean reinstall of OSX and to leave without using the Migration Wizard, anyone have any ideas? Thank you.

    If you can take a look under My Documents > Adobe > Adobe Media Encoder > 8.0 > Presets?  If you happen to see a link to alias for Presets, remove it and revive the SOUL.

  • KB955759 does not appear when I check the updates manually, but it appears with the yellow shield after you have enabled the automatic updates.

    original title: Windows Update acts confused - kb955759 does not appear when I check the updates manually, but it appears with the yellow shield after you have enabled the automatic updates.

    I just reset my CMOS settings, writing zeros for my hard drive, repartitioned, reformatted and used the recovery cd Gateway system to get my computer to Windows 98se - factory settings, except at the beginning of the recovery of the system, when it says "press any key for advanced options," I pressed a key and then I unchecked all the default (3rd party) applications including Norton and left only 2 checked: "Updated USB Hub" and "Windows Shutdown Supplement," while nothing has been installed, leaving only win98.
     
    Then I used my disc XP Home (SP2) update.  I, immediately after the upgrade to Windows XP, installed "Office XP with Frontpage, Developer Edition", then Norton 2012 before never connect to the internet.
    Then, I connected to the internet and continuously update of Norton, before ever hitting the Windows Update page. The first thing I did then was to activate Windows, and then activate the office.
    Then I hit the update of Windows "button" that says "get all your updates in one place... upgraded"Microsoft Update".  I, then, just kept hitting the page update and restart, until I find the SP3.  Then, I took a break, until the next day.
     
    I have an ADSL broadband, with a Linksys EtherFast PCI card.
     
    Then I got SP3, which installed without any problems.
    So I just kept "microsoft continuous update" manually (and reboot), until there is no more updates - EXCEPT, I always uncheck Windows Malicious Software Removal Tool - which was the only screening at the final stop for the night.  I think that I ticked the box "don't ask me about this update".
     
    Then, in the morning, after you have enabled automatic updates, I noticed the yellow shield - Windows security icon (or whatever it's called), so I clicked on it and checked it was tellimg me was available [when I checked "Custom Install (advanced users)"].  What showed was 1 update - 955759 KB.
     
    After the problem, already at the reformat (months and months), see the yellow shield telling me there are updates available, which were already installed (before rebooting), I checked manually on the internet with IE 8, pressing alt, "T", "U".  There is no updated list.  Then I checked through my history of update (twice), and KB955759 had not been installed.
     
    My update setting is to let windows download ('important') updates, but let me choose when to install them.
     
     
     
    What is the right - Windows Update (NO update important reporting) Site, or the yellow shield (reports [a] kb955759 [update])?
     
    I can not yet confirm he is supposed to be an update for XP home kb955759, because I was unable to locate any detailed documentation on this 'thing' that protect the yellow safety seems to think is a significant update.

    Comment 1: To my rquest, a moderator merged your thread in the Sub-forum Win7 updates with your wire in the Sub-forum of updates of Windows XP 20 Feb-12, c. 07:50 UTC.

    Comment 2: If you will not contact the MS Support on this issue?

    ~~~~~~~~~~~~~~~~~~~~~~~~~~

    Just for the heck of it, I have disabled the automatic updates, cleared my browser cache, checked manually, updates from microsoft (windows) and found none (with the exception of software malware removal tool windows [which I have not installed]).  Then, I turned the automatic updates on, and without even being connected to the internet, the yellow shield popped up with the kb955759 "update"...

    Repost...

    1. If you open Internet Explore (only!) to http://windowsupdate.microsoft.com and run a CUSTOM scan, KB955759 appears in results?... If so, you manage to install it and/or security updates available?

    2 after no. 1 above [<>], is the 'yellow shield' icon appears in the Notification area (on the left of your clock)?  .. and if yes, by clicking on the 'yellow shield' icon tells you that KB955759 or any other updates is ready-to-be-installed?  .. .and if so, you manage to install it?

    3 after doing 1 # & #2 above [<>], is KB955759 or any other updates offered as a ready-to-install update when you go off your computer?  .. .and if so, you manage to install it?

    ... I guess that clearing the browser cache does not erase 'downloaded' updates.

    Nope. If you want to clear the queue of the update...

    OPTION A:

    1. stop the automatic updates service:

    Start > run > (type or copy/paste) services.msc > click OK
    Double-click automatic updates > click stop
    (Stopping the service will take a moment)

    2 remove the contents of the download folder:

    Start > run > (type or copy/paste) %windir%\SoftwareDistribution > click OK

    Open the download folder and delete its content
    Close the window.

    3. start the automatic updates service:

    Start > run > (type or copy/paste) services.msc > click OK
    Double-click automatic updates > click Start
    (Starting the service will take a moment)

    OPTION B:

    1. open Internet Explorer (only!) to http://support.microsoft.com/kb/910336 [don't know the titles, etc..]

    2. make disappear/close the Troubleshooter automatically pop up.
