    Hi,

    My S3 recently started rebooting on it's own, then turned off completely. When I tried to turn it on, all I get is a flashing Samsung logo.
    I have put the phone into download mode and plugged it into my PC via the standard USB cable but Kies doesn't seem to recognize it. It just says "connecting..." then "failed to connect the device".

    Ideally I would like to save the photos/videos etc from my phone before I do anything like a firmware update, but at the moment I don't see how I could even perform the update if the device won't connect to the PC.

    Also, does anyone know if it's possible to recover data using data recovery software after a firmware update has wiped the memory and restored factory default settings?

    Any help would be greatly appreciated!

    Thanks in advance

    Welcome to the forums.
    You can try to reboot into recovery. Pull the battery for a few minutes and follow this: http://forums.androidcentral.com/sam...2-s3-tab2.html
    Wipe cache partition and reboot.
    Hopefully, that helps.

    Hi,

    Thank you for replying. I just tried this and it takes me to to flashing screen again (as if i had just powered on as normal).
    I can press On+Menu+VolumeDown and get to the downloading screen, but that's about it!

    Are there any other options at all?

    Many thanks

    If you can only get into Download mode then there's not any way to get access your data. Sorry.

    You could try using the Kies software to reload the stock firmware. Here's an overview of what to do:
    - if you don't already have the Kies software installed on your PC, download it (just search Google) and install it. The first time it runs it'll update itself to the latest version so make sure you run it once before proceeding.
    - put your phone in Download mode: with the phone completely off, press and hold the Volume Down and Home and Power buttons simultaneously, and release them all when you see the Samsung splash screen
    - connect the phone to your PC with the USB cable that came with the phone
    -- if you've never had the phone connected to your Windows-based computer before, you'll see messages about installing drivers, etc - just wait until this is done (may take 5 or 10 minutes) [I don't know what happens if you have a Mac - it probably just works]
    - in the Kies software, select the second item in the Tools menu and just follow the prompts to enter the model number (in CAPS) and IMEI/Serial Number (both found under the battery - it's ok to remove the battery at this point)
    - the Kies software should start downloading the correct firmware for your phone from the Internet; once that's done (depending on your Internet connection speed) it'll begin downloading that to the phone (this probably takes 10 minutes or so)

    Hi, my problem too. But Kies wont recognise my s6310n at all.
    It will recognise my galaxy s3
    It seems like it wont recognise it in download mode.
    The drivers in device manager all say up to date.
    Help!!!!!
