5800 does a factory reset also reset the sim lock

I have a 5800, which has been unlocked by the provider (Tmobile) so I can use an 02 sim.
The phone currently has the expired certificate problem, and as suggested in the forums a factory reset may fix this. I know that most of the phones setting will also be reset...
But will a factory reset also reset the sim lock, and lock the phone back to Tmobile ?
Solved!

No. It will remain unlocked.

    Use a alias, but you might have to use a zip code that matches the location used.
    Also if you click the right button there is a way to bypass the registration, like register later or something, Apple has it hidden. Also to bypass the internet connection to send the registration off.
    Never place your name on a Mac or PC, it's spread throughout the entire machine, in emails, on the network in plain sight etc.

  • How many times should the computer cycle on-off when doing a factory reset?

    I have a Toshiba A665-S6065 which can not boot.  Yesterday I tried the Auto Recovery by holding the 0
    while booting, and following the default instructions.  It seemed to complete without errors.  But the computer
    will still not boot.  Today, when reading the instructions, it said to expect the computer to cycle on and off severa
    times.  So how many times?  will there be any propmts or messages?  How long should the entire process take?
    How long should the computer be off before it turns on again each time?  I think I might be screwing things up
    by intervening and trying to start the computer myself because it isn't clear to me what should actually be happening.
    Could someone please tell me what to expect before I start looking at possible hardwre problems?
    BTW, I can access the Setup and Boot Menu.
    Thanks,
    kjdroid 
    NEW info:
    Now when I boot while holding the 0 key, instead of going directly to the Recovery Wizard, it goes to the
    Windows Boot Manager.
    from there the options are Windows Setup [EMS enabled]
    and Windows Memory Diagnostic, as well as the F8 option for advanced options.
    If I select Windows Memory Diagnostic I get
    File: \boot\memtest.exe
    Status : 0xC000000f
    Info : The selected entry could not be loaded because the application is missing or corrupt.
    If I select Windows Setup or F8 followed by normal windows startup or startup in safe mode then
    I get the following sequence of events.
    Starting Windows with the Windows logo.
    then the blue screen
    Then to the Toshiba Recovery Wizard, where it partitions, and does the CRC and then prompts to press
    finish to restart the computer.
    Either the computer does not shut down, or it stops and starts very quickly because all the lights cycle
    on and off but it does not appear that the start/stop light actually ever turns off.
    Then I get the Starting Windows with Logo again.
    Then the Recovery Wizard comes back but only with the screen about partitioning.  It does not
    do the recovery and CRC this time.
    Nextis the Toshiba Logo reappears again with the options for F2 or F12 for the Setup and Boot Menus.
    Finally, I get a blue screen and it appears nothing else is happening.  I let it sit for 30 minutes before I retry, because I am not sure what is supposed to be happening now.
    Also, one of my attempts, I got as far as the messages:
    Setting up the Registry
    Starting Services
    Applying System Settings
    Will continue after restarting your computer
    Is preparing your computer for first use.
    But then again, it just goes into the blue screen state until I finally decide to shut things down.
    Am I being premature or should I let the blue screen sit there for a few hours while work is being
    done in the background?  I don't hear any sounds from the computer that would indicate any type of activity.
    Thanks again

    Actually, it's kind of hard to tell you what to replace. If you have a spare hard drive laying around, go for it. It also could be memory issues (I have the same model as you) & it was my sister-in-law's notebook before I get it. The notebook had several memory dumps that CCleaner found & deleted when I was working on it. 
    I told her that I would re-install it for her to make sure there no viruses or such. After backing up the computer, I proceeded to what was supposed to work, pressing "0" at startup to no avail, then booted into the area where the system restore, command line repairs & such were, & there was the option for a factory reset, the last option. I chose that one, & like you stated, it rebooted numerous times, until finally it was through. Longest factory re-install I've ever done. 
    What led me to believe there were memory issues was during the first round of updates, it BSOD'd, another memory dump was found by my portable CCleaner. It still had the original Samsung PC3-8500 memory, so I took the memory that shipped with my MSI (PC3-10600) & installed that, then not only was all fine, it was noticably faster. Once I got it fully updated & scanned with MBAM & the ESET Online Scanner (I always do this when installing or re-installing a computer), I removed my memory & placed hers back in, then returned it to her. 
    I ended up with it about 10 days later, she said it was still dumping. Needing a spare notebook, I offered $100 for it, ending up paying $150, but still came out way better than on eBay. 
    Once I got it, I placed the 6GB RAM back in there that I had, & also replaced the HDD with a extra Crucial M4 that was laying around. Right before swapping drives, I ran HD Tune (free) on the original, there were yellow attributes, meaning that it had issues pending. It's a 500GB Seagate HDD that runs at 7200 RPM. Just so happened, I lost a 500GB Seagate Barracuda desktop HDD (7200.11) less than a month ago. Booted the computer, the screen stated "No Operating System found". 
    So it could be either the HDD or memory (RAM). Or worse yet, the MB itself. Has it been dropped? Notebooks are fairly durable, but they don't take to being dropped very well. Does it run hot? If so, there may be severe dust buildup that's causing it to overheat, that will make it BSOD. My guess is that's it's one of the first three that I mentioned above & if it's the MB, forget it. Prices are too high, even for used ones & in a notebook, it's basically a total teardown to replace it. If it's a new MB, it may cost between $200 to $400, depending on popularity of the model. That's too much to pay to repair a computer built in 2010. 
    I'm trying to give some suggestions here, based totally on personal experience on my & other's computers that I work on. However, online it's a cat & mouse game. I don't want to tell you to purchase another HDD unless it's almost 100% certain that's the issue. Which is why I asked if you have a spare earlier. Also, try reversing the position of your memory sticks (a 5 minute job), it's behind that lid close to the battery underneath the notebook. 
    Post back if you need further assistance. Someone else may have other ideas, so follow the thread.
    Best of Luck,
    Cat

  • My one year old disabled my iphone 5 so i need to "connect it to itunes" as the screen directs. I know how to do this with my laptop but it says i will be doing a factory reset. is there any way to get my phone open without losing everything?

    Long story short, my one year old disabled my iphone5 and I need to "connect to itunes" as the screen instructs. I went through the steps and it says that I will be doing a factory reset and I will lose everything. Is there any way to get my phone open without losing everything?? I'm mainly concerned about my pictures and videos.

    Once the Device is in Recovery Mode... it is too late to save anything...
    To minimise loss... after the successful Recovery... Restore from the most recent Backup...

  • HT3728 When I reconnect my Time Capsule after a factory reset, the Airport Utility shows ther message"Unexpected error. Try again." I also get this if I redo the factory reset.

    The Time Capsule is not providing a wireless connection.
    When I reconnect my Time Capsule after a factory reset, the Airport Utility shows ther message"Unexpected error. Try again." I also get this if  I cancel the Airport Utility app and restart it. I performed the factory reset again, restarted the Airport Utility and received the same error. What are the steps to debug and fix the wireless problem?
    My Time Capsule is connected to my FIOS router and to my Mac Mini. I am still able to connect to the Internet from the Mini via ethernet. It seems that the Time Capsule acts as a bridge for the ethernet connections between Internet to FIOS, FIOS to Time Capsule, and Time Capsule to Mac Mini.

    Which model TC is this? The A1xxx number from the base please.
    Try the setup in full isolation from the network.. so unplug the TC from the network.. and turn off wireless in the mini.. so you have mini--ethernet--lan port TC.. and nothing else.
    Do the factory reset.
    Now check if TC comes up in airport utility..
    If it fails, turn on ipv6 local link.. if you are using 6.3 utility this could be necessary.
    Still fails, try loading the v5 utility.. you will need to plug the computer back into the FIOS to get internet. Then depending on OS.. Lion according to your profile.. you can just down the utility.. ML takes more steps.
    See below.
    Do you have an iphone or ipad.. download the airport utility app and use those for the setup.. that can sometimes work better.
    How to load 5.6 into ML.
    1. Download 5.6 for Lion.
    http://support.apple.com/kb/DL1482
    Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
    2. Download and install unpkg.
    http://www.timdoug.com/unpkg/
    Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
    You cannot uninstall 6.1 (now 6.2 if you updated) so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

  • Does a factory reset delete all and make the new copy of OS completely fresh?

    Hi all, so I forgot my book's passcode and I reset it from the Recovery mode. All is fine, but I was wondering does a factory reset delete all and make the new copy of OS completely fresh? All the chains, registries and all, just like a fresh copy of Windows ? Or did I mixed up all...
    P.S. Strange after the factory reset and the system's downloading I got this as apps (of course some are downloaded by me)

    does a factory reset delete all and make the new copy of OS completely fresh?
    Actually, the "delete all" part is done by your using Disk Utility to erase the partition, as part of your clean install.

  • Factory reset - the what, why, and how for Gingerbread

    I wanted to share this information regarding a Factory Reset and how it is used for Gingerbread - both the what, why, and how - in case anyone is interested in the details. If you embark on this process, this thread is worth a close read. thanks to d.harris for writing this up for the SOAK group. good luck everyone and remember, YMMV.
    First, what does a "factory reset" do? The short answer is: it will return your phone to the condition it was in when you first purchased it EXCEPT the Android version will match your phone's latest update. For example, I had Android 2.2.1 (Froyo) on my phone before the "soak". My phone was updated to Android 2.3.3 (Gingerbread or "GB") during the "soak". I had some trouble with video performance in the Fox News app and missing album cover art in the Google Music app. So I decided to do the factory reset. After the reset was finished, my Droid X still had Android 2.3.3 on it but all of the settings had been restored to their factory defaults. And presumably, all Android operating system (OS) caches had been flushed. All of the data that was stored in my phone's memory was cleared. So my contacts were all gone. And I had to reactivate my phone (*228 1) just like a new phone and reenter my Google account info.
    Does a factory reset actually clear the entire contents of the phone's memory and re-install Android from scratch? (That's what I wish it did.) But I'm not sure that it does that because the entire process seems to go too fast for that. However, a factory reset does seem to do a better job of cleaning out the remnants of the previous OS (Froyo 2.2.1) than a standard "update" does. But that's not all.
    The factory reset also clears all of the apps that were installed in the phone's memory. And it clears all of the app data that was installed in the phone's memory. So you will have to reinstall all of your apps from the Android Market (or wherever they came from). Normally, you do not have to pay for them again because the Android Market remembers your previous purchases as long as you register your phone with the same Google account.
    However, the Android Market does not remember the free apps that you installed---so you should make a list of all your apps before you reset your phone so you won't forget the free ones. The reason I wrote "installed in the phone's memory" above is because a factory reset gives you a choice whether or not to clear your phone's micro SD memory card. If desired, it will leave it alone. So any apps or data will still be present on your card after the reset. However, your phone will not be aware of the apps on the memory card because all "knowledge" of them will have been erased from your phone's internal memory---you'll still have to reinstall ALL of your apps. But the data files will still be there. Regarding the "built-in" apps that come pre-installed with Android, they will also be restored to their original state and version when you do a factory reset. So you'll need to update some of them (like updating Google Maps and updating Adobe Flash from 10.1 to 10.3).
    Before you do a factory reset, you should have a fully charged battery becaues you do NOT want to run out of power in the middle of a reset---that could "brick" your phone. I always take an extra precaution: in addition to a fully charged battery, I also connect my phone to AC with the Motorola AC-to-USB charging adapter that came with it. Not only does it insure that I won't run out of power, it also keeps my battery fully charged so I have a 100% charge after the factory reset (you'll have a lot of work to do afterward to reinstall your apps and restore all of your Android and app settings back to your preferences).
    Here's a pre reset checklist:
    • Export your contacts to your SD card so you can easily restore them later (Contacts/Dialer menu > Import/Export > Export contacts to: SD card).
    • Make a list of all of the apps that you installed (Android menu > Manage Apps > Downloaded tab).
    • Get a copy of your Google account login info (user name and password).
    • Get a copy of your Verizon Backup Assistant PIN (if you use this service).
    • Turn off your phone and pull its battery. Wait 30 seconds or more and reinstall the battery and turn the phone back on. This will make sure that there is nothing hinky in your phone's volatile memory as the factory reset begins.
    • Fully charge your phone's battery and plug the AC charging adapter into the phone.
    Now you're ready to do the deed. Follow these steps:
    1. If it's not already on, turn on Google's "back up my data" option with Android menu > Settings > Privacy > Back up my data. This is required for the next step.
    2. Turn off the "automatic restore" option with Android menu > Settings > Privacy > Automatic restore. This will prevent your phone from trying to download every paid app that was previously on your phone all at once. It is much better---especially if you have a lot of apps---to install them one at a time. Plus, you may not want some of them to be reinstalled right away if you are trying to determine if one of them is causing trouble under GB 2.3.3.
    3 If you do not want to use Google's "back up my data" service to restore your wi-fi passwords and such, then return to Step 1 and turn it off.
    4. Begin the factory reset with Android menu > Settings > Privacy > Factory Data Reset. You'll be asked to confirm that you really want to do a factory reset and you'll be given the opportunity to clear your micro SD memory card as a part of the process. I chose not to clear my memory card because I have a 32 GB card with "tons" of music and other files that I do not want to have to restore (it would take hours).
    When should you do a factory reset? Everyone should do it before they give their phone away, sell it, or discard it. You don't want someone else to have access to your personal data! And, a factory reset can be a helpful troubleshooting tool when faced with problems.
    By the way, my factory reset did not help the video problem I was having with the Fox News app nor did it enable Google's Music app to find all of the album art on my micro SD card. Both problems persisted after the reset under GB 2.3.3.
    Finally, there are other things you can do to flush old data from your phone such as clearing the cache partition of your phone's built-in memory. This requires the use of its "Android system recover" menu. Even though I expect this cache data to be cleared during a factory reset, I did it after my reset just to make sure. Clearing the cache partition is usually what folks try before a factory rest so they can (hopefully) avoid the factory reset. I'll leave it to a Motorola staff person to go into that.

    OK, got it ...  the Power ON Factory reset procedures might have changed with GB ... 
    To get to a Factory reset using the Power up method:
    1.  Power Off phone
    2. Press & Hold the HOME Button
    3. Press and Hold the Power ON button.
    You come up to the Triangle with the Exclamation mark & android guy.
    Press BOTH the Up and Down Buttons at the same time.  This brings up the Blue menu of options.
    use the Up/Down arrows to scroll thru the choices. Press the POWER Button to Select the menu item you choose.
    You can harmlessly test this and just choose to Reboot without doing anything, just to see how it works in case you ever need to do this in the future.
    edit:  It was concluded in the test group that they changed this process to align it with the new DX2 as the camera button isn't hard-wired like it is in the DX. So likely they just wanted to make this process the same for both platforms.  At least it sounds like a good reason...

    When I got my new BT keyboard, I set it up on my macbook just to test it out. But its final use was with the mac mini in my living room.

    Is there a way to factory reset the keyboard, so it doesn't remember any previous pairings? I know this is possible with other bluetooth devices, I just can't find how to do it with this apple keyboard.
