    I need to root and update my tablet to Android 7.1 however I've never done it before. Can anyone point me to clear instructions and what to download so I can do this? I've been to many sites and viewed many youtube videos but nothing seems to be clear. There always seems to be something missing.
    Thanks,
    Jeff

    What's missing from those whatever they are sites and videos is probably the actual 7.x ROM you need, because I believe this tablet was never updated beyond 4.4.

    It seems there are a lot of 7.1 builds out there but what I need is easy to understand step by step instructions and the downloads I’ll need to back up the tablet and then install the new rom.
    I cannot afford to brick the tablet.

    AFAIK there are no 7.1 builds for the SM-T520 tablet. And that's why there are no downloads and step-by-step instructions for this device. Of course a ROM must be custom made for a particular device. Flashing an incorrect ROM can certainly brick a phone or tablet.

    I am surprised to hear this because I am finding a lot of people on Youtube and the Web who have done this. So this has become a bit more confusing.

    You probably don't want to approach a project like rooting and installing a custom ROM when it involves a tablet you're not willing to brick, especially if this is your first attempt. Don't take this warning lightly.

    But if you really want to do this, bookmark this page in case things go wrong and you need to re-flash a valid stock ROM to restore your Tab to working condition:
    Stock ROM download:
    https://updato.com/firmware-archive-select-model?q=sm-t520&exact=1
    Instructions:
    https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin
    If something does go wrong, hopefully it'll just be a soft-brick you can readily correct. If a hard-brick that's a worst-case scenario.

    The first thing to do is make sure you have a backup of your data. Install Samsung's 'Smart Switch' utility on a computer and do a full backup.
    https://www.samsung.com/us/smart-switch/
    If you're using Windows this also installs the latest Samsung driver, a significant point as the connectivity between your Tab and your computer is a significant point.

    You'll also need to install the Odin utility on your Windows PC to do the actual flashing. Most online directions refer to using the latest version (currently 3.13.x) but note that Odin often has backwards compatibility issues so you might find it to be a lot less hassle to just install an earlier version that's appropriate for the hardware/firmware you're working with. See below:
    https://www.droidviews.com/download-odin-tool-for-samsung-galaxy-devices-all-versions/
    Also, Odin is a Windows utility so if you don't have access to a Windows PC there's also 'Heimdall', and Open Source alternative to Odin. It's available for Linux, Mac, and Windows:
    https://www.glassechidna.com.au/heimdall/
    It's not an exact equivalent so you have to be more flexible as a lot of the menus are in different arrangements and things like that but it's functionally the same.

    As for the rooting process, try using this guide:
    https://androidmtk.com/root-samsung-galaxy-tab-pro-10-1-sm-t520
    Once rooted, you'll want to install a custom Recovery like TWRP:
    https://twrp.me/app/
    https://play.google.com/store/apps/details?id=me.twrp.twrpapp

    At this point I'd use your Tab for a day or two to make sure everything is OK and working properly before flashing a custom ROM on it.

    This last post looks like the info I have been looking for...is it still current and applicable to updating my t520 now that it seems there are apps that do not support kitkat? This would also be my first attempt at something of this magnitude.
