Lock screen forgotten on Sony Experia Z2 model

I've created a new model for my lock screen on my Sony Experia Z2 and I forgot it. How can I unlock my phone without deleting all the files? I need to keep my pictures ect. I tried to use Sony PC Companion, but for that you must have your unlocked screen and I can't unlock it because I don't know the model. I also tried to enter a code in the section of emergency call to try to unlock it and it didn't work. What can I do?

Maybe this can help:

If the above does not help, you will need to perform a repair of software using PC Companion. The process will erase all internal memory. You might need to charge your device for about 1 to 2 hours until the device has so at least 80% battery.

Make sure that the device is not connected to the computer or laptop and turned off (sometimes you have to press the power button / stop and volume until what the machine vibrates 3 times or on some devices, it must push the small button near the tray on the back of the camera or SIM).

Open PC companion-> support area-> update phone software / Tablet-> repair my phone/Tablet blue highlighted. Follow the steps, do not plug your phone until you are prompted to press volume down while plugging in the USB cable. If PC companion does not start the repair process, you may need to run Windows 7 compatibility mode (in some cases XP).

  • IPhone stuck on the lock screen

    I've just updated to the latest version of iOS 9.3 beta software (I would check to see what it is exactly, but I can't really do this). This problem didn't occur until I installed this, and it only happened on my iPhone 6s, not my iPad Mini 3. Here is a brief summary of what's going on:

    I turn on my phone using the power button. I try to hit to swipe to enter my access code. He stops and restarts.

    I'm trying to use the contact IDS. He stops and restarts.

    I try to put my password in by sliding upward to access the camera. He stops and restarts.

    Everything I try to do, it crashes. I tried turning then turn it back on again, hold the "home" button and the Start button / stop, nothing works.

    I was also in a situation where I needed to put my phone in airplane mode. I can't access the center of control from the lock screen to stop, but I turn WiFi and Bluetooth on until I turned off my phone. My watch says it's connected. My phone is done without WiFi.

    Anyone has any suggestions, in addition to a trip to the Apple Store? Thank you!

    Note: I was extremely stupid and didn't back up my phone. But to cut me some slack, I couldn't technically. The Mac I have is way outdated and does not support my current model of the iPhone, and my laptop running on Windows is not able to start. If just getting worse and worse, I have an old backup I could try to install, but I really want to take this path, because it was almost a year ago.

    If you don't have any computer that supports supported a version of iTunes how do you have installed a beta version? Looks like you've totally corrupted the phone. All you can do is restore using a computer with Windows 7 or later version or iOS 10.8.5 or later and the latest version of iTunes.

  • IPhone 6plus - text box to the lock screen

    Recently, I noticed that my lock screen got a new text box to enter my security PIN. I also see an OK button next to the text box to the lock screen that I did not see after the last update of OS. I did no upgrade of the OS recently and the current version is to 9.3.1 (13E238) (model: MGA82HN / A).

    Is this something normal? I remember that this text box came after I tried to install Citrix Mobile Workstyle to configure my mailbox in the office. Is this a problem? What should I do to restore it to normal screen or Original (without text box and the OK button).

  • notification message does not appear in the lock screen

    Hello world.

    I've been an IOS user for about 3 years.

    Before 2 weeks, I bought a compact Sony Xperia Z3.

    I am trying to know the Android mobile operating system, but it is still quite difficult for me.

    I hope you can answer my questions and make me one day an Android user better.

    My question is simple.

    Can I have notifications in the lock screen for my messages unanswered and calls or other notifications that I missed?

    I don't want to open all the time the screen lock to see who was my call without answer.

    I tried all the settings, but it did not work.

    If there isn't a way to do it, is there any app?

    Floatify is also a good app for the lock screen notifications. I'm also new Android after 4 years with iPhones. It is difficult to get used to!

  • Why don't unlock the lock screen?

    I know this is a long post, but I would be very happy if anyone with time on their hands to read.

    My computer works well and has had no virus since I installed windows8 (a few months ago), but today, he worked, and I rebooted, then the keyboard and mouse would not unlock the screen no matter what I do! Normally, when I click or press a key, the screen will slide up and he asked me my password, but now, it won't work.

    I tried different mouse and keyboards and all confirmed working on different machines. My work of mouse and keyboard in my bios and windows 8 s shift f8 mode. I tried different ports. I tried to unplug all USB ports and then plug on the lockscreen. I managed mode shift f8 and tried several options. Safe mode produces the same result. I tried to system restore but it gives me an error report something to do with my antivirus avira. After a Google search I found avira secure systems can't do system restored until avira is uninstalled, which I just can't do it right now.

    While in the lockscreen, I have several signs that the system is not completely frozen. The changes of time. When I unplug my USB WiFi adapter, the icon changes to WiFi and it changes back when I plug it back in. Initially, my keyboard volume knob does nothing but after spamming all the buttons, turn the volume change the volume, as indicated by the meter of volume of windows 8.

    Please help, I need to use my computer! I would prefer not to have to restore it because I don't want to lose a 2 TB of HDD to a value of things. I either need to find a way to uninstall avira has no access to windows and you try and the restoration of the system, or find a solution to the question itself.

    I tried to follow an online guide on how to uninstall programs with cmd, but it failed. I typed in wmic and that the command was successful, the next step was to type in product of is name, but who gave me an error code and it said invalid class. After some research, I discovered that x 64 systems do not come with preinstalled WMI command-line, but I can't install it without access to windows.

    Data sheet:

    Windows 8 x 64 professional
    12 GB Kingston hyperx 1600 MHz ram
    Stock of amd phenom ii x 6 1050t 2.8 GHz cpu
    And gigabyte 6850 GPUs
    ASUS m4a89gtd pro/usb3
    Microsoft sidewinder keyboard
    Logitech m500 mouse
    Alfa awus036h wireless adapter

    Thanks in advance.

    Edit: PS in safe mode, the lock screen is a reason ignored. He starts the password entry screen but the mouse is nowhere to be seen and the keyboard does nothing. The thing hits line of flashes.

    I would like to do a refresh of the system but need an installation disc and I've never had a physical disk, I downloaded an upgrade for windows 7.

    Hi William,

    Thanks for posting the query on Microsoft Community.

    If I understand correctly, you are unable to open a program as the program crashes. Don't worry, will help you with the question.

    1. What is the brand and model of the computer?

    2 does on all programs or only one?

    3. you receive an error before it crashes?

    Try to put the computer to boot and check if it helps.

    This will eliminate the conflicts of software that occur when you install a program or an update or when you run a program in Windows. It starts Windows by using a minimal set of drivers and startup programs.

  • Reminders do not display or stick to the lock screen in iOS10

    IOS10 (10.0.1 and 10.0.2), on an iPhone (I use an iPhone 6), reminders are no longer reliable. I had several cases where the callback doesn't show even on the screen lock and many more times when the recall won't 'glue' to screen lock for more than a short period. Before iOS10, when you said to remind you at a certain time or place, the recall would display on the reliable lock screen until she has been marked as "completed".

    It is a major issue for people who depend on the application for the important tasks and calendar. There is a thread of any discussion on this point, for some reason, has been marked as "solved" even if a large number of people continues to post telling him that there is a problem for them too (as the thread located here). I wanted to start this new discussion which we hope will remain open until it is effectively resolved.

    Thank you!!! This is a HUGE problem!

    Since the update I had to reboot my phone EVERY day.

    Is the stick of reminders... or they do not. Lately they don't yet show upward. Then other things stick to the lock screen can't get rid of.

    Currently this feature on the phone is USELESS
