    actually when you download second update and installing give atleast 40 min to complete,because it downloaded almost 725MB ,in order to install it will take time,at that time plug charger,leave phone for 40 min.
    now flash your hanged lumia with Nokia care suite ,just Google it , its need .net 4.5.1 download offline file to pc,you can reset it
    after reset,download dev preview app ,restart update process..you need 750MB wifi data to update to 8.1

    Try plugging to the charger and leave the phone over night.
    At certain times the updates will hang and need a long time to finish.
    I don't know why this happens.

    when i hold down these buttons the hanging screen vanishes but nothing happened and when i left these buttons the phone restarted but same thing happened again .
    actually it is not hanging it is just not completing the installation process .

    Here's a link with a little info about NSU:
    NSU retail 4.1.0 with Lumia WP8 dead-phone recovery mode. Official Nokia Software recovery tool. | NPU]WMPower User and NSU

    Get Nokia Software Recovery tool here: NSU

    After installing NSU on your PC the application will probably update.
    Plug your phone into the PC after the update then start the recovery.
    Your phone will end up back on the last official release just like it was a new.
    You'll have to start all over with accounts, apps, etc...

    Good luck.
