Black screen after startup (no home screen)

I was just with the Firefox browser, looking for patterns (no piece, first... use airplane mode and not wifi) and when I clicked on the cog icon in Firefox the buggy device. He showed me a message saying that the home screen has crashed. Now the device boots (displays the logo of LG, the animated Fox, my carrier logo (Vivo, of the Brazil) and Firefox OS logo, but it goes to a blank screen (it is actually a black screen with high bar appearing, showing that it is on that plane and battery.) If I press the home button (or hold it) the phone vibrates, but nothing happens. If I pressed the power button a menu appears with: "Turn airplane MODE" (which is annoying because it is already on, but if I choose what to disable), "Silence incoming calls", "restart", "Power Off". There is the option "Cancel". Each of them works, but I don't know what to do.
Oh, I tried to bring together the power, them increase the volume and the buttons on the home screen when the phone is off, but nothing happens. It turns when I release the home button. In addition, the volume and lock (or power) buttons works and change the volume / locks the phone...
What should I do?

The phone is a LG Fireweb, bought in the Brazil.

Update, I tried to discount backwards, looks like you need the power, the House hold and volume KEYS until the LG screen appears, then release them. Worked well after the reset (so far).

    No saving necessary data and re-installing Windows Vista might be the best option, but here
    are a few others.

    You can save your files by putting the drive in another computer as a 2nd disk (best) or external
    Drive USB enclosure and then backup to removable media such as CD, DVD or other USB drives.
    Of course a real store of the computer or the manufacturer of your system can help to recover the files.

    Or you can use a boot Ubuntu CD to back up data.

    You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel
    -Double click - Driver tab - click on UPDATE driver - device Manager - map - graph
    then right click on the device and UNINSTALL - REBOOT.

    A method to try to get to the desktop (try in normal Windows Mode without failure) is CTRL +.
    ALT + DELETE - Manager tasks and tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - and then
    on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is available by
    repeatedly tapping F8 as you start. CTRL + SHIFT + ESC also begins the Task Manager.

  • Black screen on startup after windows update 7 crashed


    Hope you can help.

    I have windows 7 64 bit installed and everything was fine until last night.

    It seems a windows update has been downloaded and when I turned my PC it was installing the update - the projection of the usual blue installation screen updates etc.

    It took a long time and it seems to me he had crashed, has frozen I couldn't move the mouse.

    Yes I know it says that you should not turn the PC while the update was the installation, but for me, it seemed like it had crashed and frozen upward.

    So I decided turn off the pc and he left the next day to check the pc.

    I turn on the pc and select windows 7 in my list - I have Setup dual boot

    I get the message that windows did not start properly, so I select boot normally - I get the swirly logo appear and then just a black screen with the cursor that responds to moving the mouse.

    There's just the black screen with the cursor and pass to the next step of the login screen.

    I think because of the windows don't update not install correctly and turning the pc off this contributed to hang on the black screen.

    I tried to start in safe mode to see if the same problem which he passes, I can connect via the SafeMode very well and have the available login screen and entered fine windows via safe mode.

    I get ideas as to what I can do to solve this black screen?

    To confirm once again, this has happened after a windows update tries to install, but as I felt it had crashed I turned off the pc - no drivers graphics etc. have been installed for a long time - only this update of windows

    I hope you can help, thank you very much


    EDIT: Just to add that I tried to do a restore point, but as I turned it off I don't have the option to do so.

    Hi Martin,

    Thanks for the reply.

    I tried something last night after going through loads of forums.

    I tried F8 for advanced startup options, and I'll give you good last thinking setting up a go, known guess what, it worked!

    I was able to return in Office windows as usual, I even installed the update that it crashed on the last time, well, I think that he reinstalled the last update, it crashed on... anyway, I think I'm back to normal, but will check it out tonight but if you are still having problem try what I did It can work for you.

  • Windows XP Home, black screen after loading screen (seemingly unique problem)

    Hi all

    I am trying to upgrade to service pack 3 Windows XP home on my old computer from eMachines T2838 and experiences a @# *! a time to do it. This is the third time in 2 days I had to wipe my HD and re - install XP, because of some problem installing updates which has damaged the operating system.

    Here's my current situation.

    Yesterday, after the failure of the HD for the second time (computer got stuck "performing cleanup" on SP2, forced a reboot, got a restart loop after, would not load Windows) I installed XP, update to SP2, then downloaded the service pack real itself. He has installed fine and asked me to restart.  I respected that, and the computer restarted. As soon as the "Loading" screen popped up, I knew that something had gone wrong.  When I started on the desk, I was stuck in 640 x 480 w / 4 - bit color graphics mode. Could not be set. So, I thought, okay, let me reboot Windows and see if he "rediscovered" the integrated video card. Well, I restarted, and the "loading screen jumped into the appropriate color mode / resolution, so I thought that I was in the green."  Well, after that, all I get is a black screen. No message 'No signal!' or anything like that.  Even tried a few instructors that I have. Looked around online, has seen the references to "Last known good Configuration" 'safe Mode' etc etc.

    I tried all the options on the list of F8. Either she freezes at Mup.sys xxxxxx or boots up to the loading screen and then goes black after. I can hear the HDD does it's thing for a bit, so I don't know it is loading this screen "check to activate the automatic updates" which appears after SP2 is installed, but I can't.

    Use the recovery console, (did the repair option the first time after it kept restarting, Windows took 5 minutes to start an IE6 get locked every opening, so had to wipe and re-install) typed "chkdsk/p/r" and he did his thing for about 30 minutes, rebooted and still have the same problem.

    I don't know what else to do. I REALLY want to redo everything this a fourth time, only to to have screw it up once again, and I don't know how many times I can use the key I have on the back of the computer.  (Using a retail disk and an OEM key, Finder product key changer.) -A Microsoft Support Officer showed me that one. Quite handy.

    People do you have any suggestions?  I would really appreciate it.

  • Vista Home Premium, black screen after my login and my password entry

    Hi all

    A month ago I bought a new Dell Inspiron 15 comes pre-installed with Vista Home Premium. Like many others I am now a problem with a "black screen" that hang up the machine after my login and my password. "

    When I start the machine it seems to load normally I do it at the login screen, I select my account (admin) and enter my password. The windows logo appears, and then a status bar starts indicating that the OS is laoding. Shortly after that I get a black screen on (which means that the display is on but list black). I tried to start safe mode, but I get the black screen it so.

    Like others the machine was working great until this point. I was using AVG Free edition and I am always very careful on viruses.

    recently installed an automatic update of windows 8.1. Now, I get a black screen after the home page. I can load the Task Manager and access the internet. tried to go to the SafeMode to start with f8, but several attempts failed. I updated my graphics driver from AMD today and same black screen.

  • Satellite C660D 15F - black screen after startup

    Satellite C660D 15F

    Hi guys,.

    I have a big problem with my laptop. When I started to-go from sleep - two days ago I heard the computer starts normally but the screen remains black. No mater how many times I tried to restart, the screen shows nothing, no message no picture. The normal operation of the side light remains on but the keyboard lights stay offshore. I can hear the computer normally (the fan etc..).

    I tried to hit SHIFT F8 start buttom on the first night, and the image was on the first attempt when I started the machine and everything seemed normal again! The next few days, I got a black screen once more and the case never worked again, no matter how many times I tried.

    Can someone help me please get out of this mess? Has anyone had a similar problem? How do solve you?

    My machine is now exactly four years.

    Thank you very much for your ideas! I really need to access some files on there!


    Disconnect the power and remove the battery. After doing this press the power for 30 seconds about and try to reset your machine. Leave it for a while and try to start with power current only.

  • My Satellite L505D goes to a black screen after startup

    It seems to boot up properly and everything. It starts Windows 7 and goes to the user selection screen, but since there is only 1 user, it only says: Welcome to the loading circle. But when he tries to load the page office or home or whatever you call, all that happens is the mouse.

    I can move the mouse normally, my anti anti-virus pop ups see the place if necessary. On my last attempt to try to solve the problem, I got my user to open the file, but has happened automatically. I tried taking the battery twice thing. If any ideas on why the screen just looks like a black screen and the mouse visible.

    PS: I use the keys ctrl + alt + del function to get these options appears.

    On this virtual path, it is not easy to understand why all this is happening, but what you can try is to start the operating system in safe mode and roll back the OS to an earlier time to see if it works.

    Can you please try this and post comments.

    Do as a first step. Later, we see what can be done.
