P780 boot loop after factory reset

From couple of days ago I started to get popups saying "android ____ .com" or something and every time I clicked OK the message would pop up again not letting me press anything but the OK button continuesly.. so I powered off the phone I powered back up again and my phone wouldn't boot anymore. The screen said "Encryption Unsuccessful" and then there was a "Factory Reset" button right below - nothing happens when I clicked it So I went on and performed a factory reset by entering recovery mode (power button + volume up + volume down) and after it didn't work I went back to recovery mode and tried "clear cache" which didn't work so I then went to factory mode (power button + volume up) and cleared data by selecting MMC or something (it was in chinese) What happens next is, the phone enters a boot loop. It boots, shows the Lenovo logo, then turns off, then boots again, Lenovo logo, turns off, and so on. I wasn't even able to turn off the phone so I clicked that red reset button at the back I didn't try removing the battery or SD card How do I go from here?

I would like to add, whilst I was using the pin clips on the pins near the bios chip, I let the system run until it would beep.  During this time, the CPU fan ran really really hard.  Have I damaged the CPU somehow?

  • Cisco 7941G phones will not boot up after factory reset.

    Cisco 7941G phones will not boot up after factory reset.
    The following happens.
    1. Speaker light lit (Green)
    2. Phone displays a firmware upgrade page (see attachment) for a few minutes. (Doesn't seems to be upgrading, but it "saids" upgrading)
    3. Saw Cisco logo with a Java Powered page.
    4. The whole thing loops again and again...
    I think the reason why the phone isn't booting up is because the phone needs to know where to find the configuration/firmware files from a tftp server. I do have a TFTP server, but normally I need to go in settings to change the alternative tftp server, but the thing is that now I can't even press the settings button...
    Please help.

    How many phones were reset and upgrading at one time? What is the setting of the TFTP Maximum Serving Count (Advanced TFTP Service Parm) on each of the TFTP servers?
    Sounds like too many devices trying to use TFTP at once.

  • Boot Loop after BIOS reset

    Some kids at the school I am stated at put passwords on the BIOS, so we used the pins next to the BIOS chip to reset the BIOS.
    This has worked to clear the BIOS passwords, but it has had the unfortunate side-effect of putting any computer we do this to into an endless boot loop.
    The computer gets as far as a screen where an option to "start windows normally" (among others) appears.   Sometimes the windows xp logo can feintly and briefly be seen before the computer restarts its self. 
    I have re-created the issue with computers that didn't have passwords on the BIOS by resetting it anyway and the symptom persists. 
    What am I missing?  I've tried using the BIOS options to optimize the setting and I've also take a compter that does boot (same make / model) and mantually copied over the settings in the BIOS. 
    Still can't get it to boot.
    I can flat load linux to it, but windows won't take, either via a PXE boot or disk.  The install seems to go so far as to unpacking the files, but isn't able to boot into windows sufficiently to do the rest of the install.
    :s
    Any help would be greatly appreceated as we now have 11 out of 24 computers doing this.

  • Z68a-gd65 boot loop after bios update using USB

    Hi there,
    My  z68a-gd65 (G3) went into a boot loop after I did a bios update from a USB key that I installed using the latest BIOS version on the MSI site 7681vP8.zip
    After the system restarted, it keeps booting up for 5 seconds and then shutting down, I removed all external devices and the Geforce GTX 550 Ti card and used the onboard card, but still no change...
    Is there a way to set the board to factory defaults again???
    Marcel

    Hi there,
    Maybe for others to solve the same problem, I found out what was the cause of this problem, I had a USB/Firewire card installed in the PC, after removing it the BIOS update could proceed from the USB stick as planned.
    After the update though, my USB/firewire card can still not be installed back into the slot, because doing so will make the boot loop appear again, very odd!
    Does anyone know why this new BIOS will not work with the card that has been inside my PC for 2 years???

  • Data recovery after factory reset

    I have seen people write that data recovery was possible after factory reset below the jelly bean OS versions on android but iphone is impossible.
    So I wonder what is security technology for data protection on iphone.
    Let me know security technology. (data encryption, data fromat algorithm, whatever about data protection)

    Follou-up..... reading other questions/answers on this forum seem to indicate I'll have to "cherry pick" specific saved data items from the desktop "Shortcut to System Recovery Files" --- a long process.   Is there a quicker way???

  • Time capsule setting up problem after factory reset

    What's the next step after factory reset to set up my time capsule again???
    i did factory reset for 4-5 times and i cant use my time capsule to create a network, join an existing network or anything else.
    i also tried normal reset but still nothing can be done.
    There is always a message at the end " an unexpected error occured. Try again"

    Plug the TC into the computer by ethernet..
    Make sure the computer has no other network running and nothing else is plugged into the TC.. just TC Lan port to the computer ethernet.
    Now press reset and open airport utility.
    Generally you will have no issue once it is isolated. Do the setup and then you can disconnect and put it back in the network.
    If it doesn't work, is the LED on the TC flashing amber or what??
    Is the ethernet port connectivity LED on?

  • Recovering data after factory reset (security issue)

    Hello there,
    Recently a friend of mine asked me how to erase all data on an iPhone ? I pointed to him to "factory reset".
    Now, I see a bunch of websites that show how to recover data after factory reset using their software, not sure if they work as advertised or not.
    What I would like to know is if the user wants the data to be erased and non-recoverable, is this the best option or if there is any other option available in iPhone that can make the data un-recoverable. We want to make sure the data is un-recoverable after factory reset.
    thanks
    Ashish Shah

    unfortunately this doesn't answer my question.
    I do know the option to "erase all content and settings" in iPhone.
    What I want to know is to make sure once done, no one can recover that data back. Since this phone will be sold off to some stranger, we don't want them to have access to the data.
    Here are a few websites from my just preliminary search results that show how to recover data.
    just google "extracting data after factory reset iPhone" and you will see a bunch of websites offering their products to recover. So I want to check if this is so simple, how can we really make sure the data is wiped off clean.

  • No audio, after factory reset,flash install,SoundMax & HDA audio drivers won't install

    My problems are:
    No sound with Youtube or the laptop itself
    SoundMax won't install either though I downloaded HDA audio drivers it requested.
    Flash download stuffed up my SoundMax after factory reset.
    I decided to do a factory reset after Youtube starting slowing down. After reset it (Youtube) kind of worked better
    then the audio disappeared from the laptop. The drivers, SoundMax Audio was gone (greyed out).
    I downloaded the Audio driver from Lenovo website for my X31 but SoundMax install wouldn't install because it kept saying HDA Audio drivers weren't installed.
    I downloaded it from here:
    http://support.lenovo.com/en_AU/research/hints-or-tips/detail.page?&DocID=HT072373
    So I went to HP site to download HDA audio drivers, then the SoundMax Audio reappeared and I had sound on my computer.
    HDA Audio drivers link at HP website (since Lenovo doesn't have it):
    http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?cc=US&lang=en&swItem...
    When I downloaded latest Adobe Flash, the SoundMax Audio disappeared again. So at the moment I have Youtube video without sound (and Firefox keeps telling me to download Flash?)
    No sound on IE as well.
    Would appreciate your help. Thank you very much.
    I'm using:
    ThinkPad X31 (2673-QU6)
    Based on 2673-N7G
    Win XP Pro Service 3 with recent updates
    Firefox (latest) with add-ons
    Solved!
    Go to Solution.

    You need to install the modem driver too.

  • 4404 WLC stuck in boot loop after upgrade

    In prepping for the upgrade to 4.1.185.0 I've got two controllers at different sites stuck in a boot loop after applying 4.0.219.0. Units will not even get to the <ESC> option menu.
    ANy ideas?

    Did you clear the configuration on the controller by using Option 5 in the boot menu? This will corrupt the boot image. You should not choose the clear config (option 5) from the boot menu on controllers running 3.2.78.0, 3.2.116.21, 3.2.150.6 or 3.2.150.10, 3.2.171.5 or 3.2.171.6, 4.0.155.5 or 4.0.179.8 and 4.0.179.11.

  • My ipod is stuck in a boot loop after restoring

    My iPod touch 4g is in a boot loop after restoring
    It will boot up but 10 seconds later after the unlock screen it goes into the apple boot screen please help!!!

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Windows 10 Upgrade infinite boot loop after reset

    I did a Windows 10 upgrade on an old computer with these specs:-Windows 7 Pro- 64 bit-Dell Optiplex 755-4 GB RAM-Intel Core2 Duo processor Everything ran fine after the upgrade. However I wanted to do a clean install. So I did so and chose the option to not keep any files or programs. It went through the process and was stalled at 99% for some time. I let it run over night. I came back and looked at it about 16 hours later and the 99% was gone, but the "hourglass" was still going. I pressed Escape and then CTRL+ALT+Delete to try to get it to respond. Now it is stuck in an infinite boot loop. It will reboot and then after several minutes it brings up an error message of "Your PC ran into a problem and needs to restart...- Inaccessible boot device." Then it restarts and the loop starts over.I've tried booting into safe mode using F8, but...

  • IPod Touch 4 has gone wonky even after factory reset!!!

    I have an iPod Touch 4. It has the latest o/s (6.1.3, there isn't anything newer available). I am running the latest iTunes. I have a pc with windows 7. Everything was working great up until about a week ago. All of a sudden my ipod crashed and got stuck in a boot loop... I couldn't get it to respond any other way so I did a factory reset and restore. I had massive issues after that -- most of my apps wouldn't sync/install. Very little would work. Basically it's useless. So I did another factory reset and restore. Same problem. Must have done this a dozen times. It takes a long time to do a restore btw and it fails on top of that...
    So today I finally did a factory reset and set it up like new instead of doing a restore. I installed only a few apps, not all. It appeared to work ok. I just did a sync and started to install more apps and viola -- funky iPod again... It appears to work, apps open, you can even play or use them. Then randomly it turns screen off, closing the app and appears to reboot (but it doesn't reboot every time)... Things do work on it, I get push notices ok... I had turned off the screen lock thing so I didn't think it should be turning the screen off anymore...
    I might add, even during a sync it appears to be doing something -- it beeps, screen goes black, apple logo come up, it comes up again but its super fast so I am not sure if it's rebooting itself or what? The sync just sits there waiting... So it never appears to be dropping the connection...
    This is driving me batty!!!!!!!!!!!
    I tried doing searches online and it appears I am not alone... Is this some kind of problem with the latest version of itunes?
    Is it my ipod going belly up?
    I bought this used off amazon about 1 1/2 months ago... Should I contact the seller for replacement?
    Suggestions?
    If I took it to the apple store I am sure it's not under warranty so I don't think they would help me...
    Everyone please chime in cause I would LOVE to use my ipod again! It's not much use to me in this state!!!!!!!

    Well my friend, I do appreciate the help!
    it looks like it may have been a bad app or multiple bad apps... or maybe even corrupted stored data...
    it appears to be working ok now -- i've added about 1/2 my apps back... a lilttle at a time... doing backups before adding anything new each time... and it's ok... there were only a few games I cared about keeping the data for and I was able to pull that data out of some old backups using iBackup Robot... careful to pull ONLY the data for a handful of apps, NOT all the data for everything... I even decided to give up on 2 games and start over again cause I suspect they may have been part of the problem as they have new updates all the time and the updates are usually flawed.. so i just started over on those 2...
    so the lesson Illaass to learn here is, before you jump in going on about how it's a bad logic board which it appears NOT to be -- let the discussion I was hoping to have with others and not you (no offense, others who actually have had this problem not someone parroting back what he's read) take place...
    and if you see someone posting a similiar problem to mine -- suggest what I did first! cause most of us (including myself) don't have $199 sitting around doing nothing to buy a new ipod with... lol
    but i do thank you for trying -- your heart was in the right place!

  • DROID in boot loop after OTA update

    Just accepted the update today.  After phone updated and attempted to reboot...its in a continuous boot loop.  How can I stop it?

    Try taking the battery out.  If it still loops when you try to power it on, then the only other thing to try besides a factory reset is to take it to a verizon store and see if they can do anything.

  • After Factory Reset - the dreaded 3F0 message "please install an operating system".

    I have seen numerous threads on the 3F0 message relating to missing HDD/OSes but none seem to match mine.
    I have an (albeit old) HP Envy 13-1050EA,  I decided to completely refresh it and go back to factory reset state.
    The reset completes succesfully, the machine then starts it's setting up the OS (Windows 7 HP).  It reboots a couple of times as expected then suddenly throws the 3F0 message Just after its finished installing drivers.
    I have performed the usual HDD tests - the disk is there, all present and correct.  In fact I have tried it with various HDD and get the same results:
    I can install an OS from OEM (windows 7 and windows 8) without a problem, but ONLY with the recovery disks do I get the 3F0.  But I would like a factory reset with the original Image that I paid for originally - not just the OS (The Linux front etc)
    How do I get the the machine to recognise it has been installing the OS for the past 20 minutes, is HP's recovery faulty in some way? 
    I have two of these machines - identical spec - if I cloned the drive of the working model is it easy enough to change the Windows 7 License Key - are there any other keys that I'd need to be aware of?
    Any help would be gratefully accepted.

    Welcome Blue.
    You can clone the drive and change the product key.
    You must make sure that they both have the same version of Windows COA's.
    After you have the cloned drive booted go to START then COMPUTER then SYSTEM PROPERTIES.
    At the bottom of SYSTEM PROPERTIES you will see CHANGE PRODUCT KEY.
    Click on it and put the product key in that is on the bottom of that laptop.
