Xperia Z1 stuck in boot loop after upgrade to lollipop!

Hi,
I tried to upgrade my Xperia Z1 to lollipop on my macbook - but it failed due to something about update server error. Now , the phone just tries to boot, shows the sony and xperia logo, backlight comes on - and then shuts down and cycles through this! I tried using EMMA and the phone is locked and says to go to sonymobile/update - but that says to use PCCOmpanion -  I have tried to use PCcompanion on a PC and folloed the instructions and it shows the start screen, select screen then just tells me to take the battery out and put the usb cable in again - obviously can't take the battery out - so i shutdown, put it in fastboot and it just does the same.
HELP! Followed the upgrade procedure to the letter and now my phone looks like its bricked....hope sony will replace as it was their fault! Or can someone help me!?!?!?
Solved!
Go to Solution.

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.
Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).
Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

  • 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.

  • Xperia Z1 stuck in boot loop

    Hi there, I bought my brand new Xperia Z1 2 weeks ago, the first few days, it work perfect but some time have to restart because it keep losing mobile data, after a few day, it start to having boot loop. I tried everything that other post said like hard reset and leave it more than 30s, take out the sim card and sd card, but still, it can't start up without having boot loop. It just appear Sony logo, then Xperia, then restart, heat up and keep continue like that.
    I tried to factory reset and flash a new room with SUS, work perfectly again, after 3 days, the bootloop start happen again and the mobile data keep losing.  Any idea to fix this ? Thanks in advance

    Exact same symptoms; just after two days using my brand new Z1. Took it to the service and still waiting to hear form them for more than 10 days! In my case, when the phone rebooted, there was no background image at all; all I had was a pure black background (the widgets and all were still there and functional) and after about half a minute or so, the phone rebooted itself. If I let this go on for some time, the phone sometimes booted up normally. Funny that during the reboots, although my SIM was locked, I was never asked for a PIN.

  • P67A-GD65 (b2) stuck in boot loop after bad flash

    Hello,
    My mainboard is stuck, I can't open bios setup, (even tho it appears in f11 menu), and it won't boot on any device.
    I removed every hard drive and DVD, and tried to boot on DOS with a usb, but it won't even boot DOS, and no usb device appears in f11 menu (I tried every usb ports)
    And I can't enter bios setup (it just reboots)
    Initially I was trying to update my bios because some features I wanted were not in my old version. But I think Avast blocked the update program (E7681v43.exe opened in an usb) and when I restarted the bios flash failed, and my PC entered a boot loop. When I press f11, it's a new interface so some things in the bios updated.
    The only message I get when I put the E7681v43.exe and E7681IMS.430, or the files for v1j (oldest version before ivy bridge support) on a fat32 usb stick (tried formatted, and formated with Rufus), a red message appears saying "bios me updated ... file not found."
    Same thing if I try the MSIHQ flash utility, it doesn't work as my PC won't boot on the usb.
    I think my motherboard is bricked and the only solution is to send it to msi to get a working bios.
    My motherboard p67a gd65 (b2) (the one with bad sata 2 ports) and it doesn't appear in the product name list anymore to register it on msi...
    It was bought the on the 19th of January 2011, I hope I can still ask for msi for help!
    I'm looking forward to your opinions on my issue, and sorry for the long text.

    older b2 cannot be updated to the .4xx
    you have to send the mobo to be replaced with newer revision
    Thanks! do you know where can I ask for a replacement?
    I can't register it on msi, and when I ask a question and I give the serial number it just abords...
    I already send an email to msi France (I live in Belgium). But email are too slow usually.
    and what about the secondary bios, no way to repair primary bios with it?

  • Sony xperia Z1 Stuck in boot loop.

    Hey Guys,
    I have a new Z1 that randomly stops getting service when I turn it off and try to turn it on it flashes sony then Xperia then a black screen and then back to Sony. After being off for a while it will finally allow me to start it up. Any ideas?

    once you make it actually started and running, long press the power button for the shutdown menu. Then long tap on the "turn off" option, and pick safe mode when it pops up.
    This will make your phone start in fail-safe, with all non-stock services and apps disabled, so you can see if there are some apps that cause this. Try it several times, if the phone boots normal in safe mode every time, uninstall some apps that you recently installed and check if the problem is gone.
    If this doesn't help, you can always make a software "repair" with Sony Update Service (download here if you don't have it already   http://www.sonymobile.com/in/tools/update-service/ ) But remember to backup your data first.
    When everything have failed already, try to read the manual.
    Kudos mean I am helpful. Am I for you? Then support me back

  • [SOLVED] Boot loop after upgrade

    Hi all,
    When i try to boot arch, even in fallback mode, boot fail and go in loop.
    loop happen just after the display of nvidia logo, then it try to do something (not showed in screen), it fail, and the nvidia logo is showen again.
    I can't access to GDM, i can't turn off computer (have to remove battery from my laptop), i can't access to terminal/console/virtual console.
    Last things i've made:
    - full update system (pacman -Syu)
    - changed /etc/environment adding this line (i was trying to solve tearing problem):
    CLUTTER_PAINT=disable-clipped-redraws:disable-culling
    CLUTTER_VBLANK=True
    nothing seem to work
    i've already removed the 2 added lines from another linux distro i've on the same computer, so i don't think /etc/environment is a problem here
    don't know what to do and how to solve...
    any hints?
    thanks
    Nico

    I have exactly the same problem,
    Did a full update with pacman.
    I haven't updated with yaourt, because I had some problems and rebooted, but now I cannot access the terminal.
    If I switch to tty1, I constantly switch back. Ctrl+Alt+Backspace is not enabled and I'm not sure it would work.
    I've tried to only boot to runlevel 3, but gdm is in the daemons or I did something wrong because I boot into X again.
    Anyone have an idea how to solve this?
    Thanks
    EDIT: solved it for me
    Step 1: on boot let GRUB only boot to init 1
    Step 2: change config files so not to start X
    Step 3: reboot so you have networking support
    Step 4: search in aur if you have a your own cairo package (pacman -Qm)
    Step 5: rebuilt that cairo package
    Step 6: start X
    * step 2 and 3 are maybe not needed if you know how to get networking in init 1. Re;ember to undo the changes in Step 2 so X starts at boot again.

  • Can't sync iPod and stuck in restore loop after upgrading to iTunes 7

    I cannot restore my iPod using my desktop, so I use my laptop to do it and it seems to work and I can transfer music to it, but when I reconnect it to my desktop, it tries to erase and resync with the other iTunes library. It seems to go through and I can see the status of all the songs being copied to the iPod, but when I then disconnect to see if it happened, it shows no songs. When I reconnect it to either the laptop or the desktop, it tells me to restore it. Only the laptop will restore, the desktop gets in the restore loop. I tried the selective startup, the drive letter change, the reinstall of iTunes, nothing works. Can anyone tell me if this is an iPod error or a software problem?

    Try the following. I expect you will have to let the battery fully drain.                                              
    - 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 another cable       
    - 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.

  • Iphone 4 stuck in boot loop after failed ios5 restore/update

    i'm sure this question has already been answered and i just can't find it.  After attempting to update/ restore my iphone 4 gsm to ios 5 it recieved an odd error code something with =yes at the end. Now my phone just keep rebooting: apple screen, spining disk, loading bar like during a restore for 1 second then it repeats this process. Itunes will not reconized the device unless i force it into dfu or recovery mode. I have tried everything to get it to restore dfu, recovery, the previous firmware 4.3.5 and everything gives the error "this device isn't eligible for this build." any tips possible sulotion would be great as of right now i have a bricked iphone 4

    I had a similar problem on mine with the same symptoms so I called apple since my PC couldn't even see my iPhone 4 when it was plugged in. The rep told me to hold the home button and on/off switch like when doing a hard resatart and hold those two buttons together for 10 seconds and once 10 seconds pass then release the on/off switch but continue holding the home button until the phone shows up again under "devices" in iTunes.

  • 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???

  • IPhone 5 stuck in portrait mode after upgrade to iOS 8

    iPhone 5 stuck in portrait mode after upgrade to iOS 8.
    Phone was fine before the upgrade, iOS 8.1 did not fix the issue.
    Have done a factory reset at Genius bar and they say it's a hardware issue and have gotten this response below:
    "Now, when you perform an update to any iOS device many system checks are run to verify that all components are working as they should. This is part of the firmware update process. When these checks are run sometimes issues are detected, even if all seemed to be running well previously. When this happens one of two things can occur. Either the hardware will be deactivated completely, or it will be locked in a state of use so that the device can still be used. In the case of the gyroscope for screen rotation, the firmware locks in place so that while not perfect, the device can still remain on some functioning level. This is what appears to have happened when you updated. The software itself did not cause any failure, but it detected a currently upcoming issue and prevented it from becoming worse."
    All I want is a replacement but they want me to pay £199 since it's out of warranty.
    Anyone have the same issue?

    If the device is out of warranty you must pay the out of warranty replacement fee to have your iPhone replaced. If the phone was still under warranty the phone would have been replaced at no charge.

  • My 5c is stuck in boot loop!

    I have only had the phone for 2 months and it is now stuck in boot loop. It is not been jailbroken at all. It first started yesterday and it just kept resetting itself every time i went to press something, so i left it over night and it has worked all day. As soon as i got home it started again, and now is stuck on the apple logo screen and the logo just fades in and out. I have tried everything to make it work, i've tried to put it into recovery mode, i've tried DFU. I've tried to connect it to itunes and it won't even be recognized as a device! Do i need to take it to an apple stockist? and does anyone know what could have caused this? I have only downloaded apps from the app store and don't think i've opened anything i shouldn't have, Thanks!

    If you have used DFU mode correctly and you cannot restore it the phone has a hardware problem.

    Hi THGutz,
    Did you install the latest version of Lync for Android ?
    The current version of Lync for Android is

    I don’t test it on M8, but on other Android 5.0 devices it works fine.

  • 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...
