    OS update failed overnight.
    Turned on phone to see a phone icon containing a red triangle/warning signal.
    Phone is very new and not rooted / backed up.

    Found system recovery menu.
    >reboot to bootloader
    attempted both the following
    >boot to download mode
    >boot to recovery mode
    both attempts took me back to the red triangle screen

    Attempted the following
    >wipe data/factory reset
    "Data wipe complete"
    then again tried all boot options.
    No change in error.

    I do not have a working SD card to boot from.

    Thought I would try
    >apply update from ADB
    However the HTC site does not provide a ROM for the 520 model and neither does cyanogenmod..

    I'm slightly perplexed that there is no factory restore option like on most devices I have owned. The "wipe data/factory reset" just removes my user data and doesn't reinstall the OS which is worse than useless.

    I really need to get this working as I have already missed some University due to this issue.
    Any help would be greatly appreciated.

    Regards, Tim Green
