  • 1. I cannot get my Shield device to see shared folders on my Windows PC.
     

    This works on Windows 7, 8 and 10 (tested).

    You need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly.

    Set the following registry key to ‘1′:

    HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

    ... and set the following registry key to ‘3′: (you may have to CREATE it yourself)

    HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

  • 2. Why can't I write to my SD card with {insert application here}
     

    Note: Android 6.0 (aka Android Marshmallow) can affect how SD card is accessed.  Read my article on Adoptive Storage for more information.

    Since Android Kit Kat, Google has locked down security on the SD card.  In Kit Kat, a program could only WRITE to a folder within the /Android/Data/ folder named the same as the package name of the app (i.e. com.foo.packagename).  This ensures that an app cannot get to or modify other data on the SD Card.  To get around this, root users could use a tool like SDFix to remove this restriction and make the SD Card read/write for all apps.  Read access was available across the entire SD card.

    The same holds true with Lollipop.  All apps can access the SD card for reading, but only the designated folder for writing.

    Lollipop, however, allows for "elevated privileges" to apps that are code-compliant with Lollipop and are granted this access by the end user.  This does not require root access.  When an app is compliant, it will ask the user to select a folder for access.  If you choose the root folder of the SD card, the app will have full privileges to read and write.  One such file manager is ES File Explorer.  You can educate yourself more here.

    MOST apps do not include Lollipop support for this level of access.  If your favorite application cannot access the SD card to your liking, I recommend rooting and using SDFix.  Your only other choice is to write the developer and ask for Lollipop support.

    With Android Marshmallow, SDFix no longer works.

  • 5. I’m having general issues accessing my SD card/external storage. What else could be wrong?
     

    Note: Android 6.0 (aka Android Marshmallow) can affect how SD card is accessed.  Read my article on Adoptive Storage for more information.

    There are reports that if your SD card is formatted with ExFAT that you can have issues with it on the Shield Tablet.  Using a computer, copy the files off the SD card, reformat it using NTFS, then restore your files.

    There is also word out there that if the SD card partition isn't named (i.e. it is blank), Lollipop will deny access to it.  Naming it may also solve your problem.

    Your other option is to get another SD card, format it with the Shield Tablet - then use a computer to copy the files off your old SD card to your new one.

    If you have a large external drive, it may have been made with a GPT partition instead of an MBR partition.  Visit this site to better understand the differences.  If you have 2TB or less, you can use MBR in a single partition.  If you have a bigger drive, you may have to use multiple MBR partitions.

  • 9. I cannot get my computer to recognize my Shield device using ADB! It's making me crazy! What am I doing wrong?
     

    You probably don't have USB Debugging set up in Developer options on the Shield device.   Go to SETTINGS -> ABOUT.  Scroll down to the bottom and start tapping the BUILD INFO area.  A toast will come up and tell you to continue tapping - and poof, you will be "a developer".

    At this point, you need to go back to SETTINGS -> DEVELOPER OPTIONS and check USB DEBUGGING.

    Try plugging into your PC now - but WATCH THE SHIELD SCREEN!  You may get prompted to "allow" access by your PC to the device.  Make sure you check the option to always allow access by this PC.

    ADB should run correctly now.

    Another possibility is that you have older/other Android drivers already on your machine from another device.  If possible, use a different machine or a virtual machine that is clean.  Use a tool like this one to remove the other USB device.

    Finally, ensure you're using a quality USB cable - one that came with a phone (not some external charger).  Don't use super long cables - no daisy chaining cables or extensions.

    Seriously, it's probably your USB cable.

  • 14. I am getting terrible performance with Gamestream from my local PC. Help!
     

    Your local network has nearly ENDLESS possibilities of configuration; it would be impossible for us to cover everything possible here.  However, we can go over a few common issues we've seen.

    Go Wired

    Wifi - no matter how fast or how great it is - simply isn't a stable and clean enough signal to rely upon for high end gamestreaming.  Going to Ethernet is the first thing you should try.

    Power Line Adapters

    They are better than WiFi but don't use them if you don't have to.  Even if they "appear" fast enough or perform amazing with speed tests.  Gamestream requires more than just speed.  If you're having issues and these are between your PC and your Shield?  This is the first thing to eliminate.

    Weak Link In The Chain

    If you have a decent sized network, you may have a "weak link" somewhere and this is causing packet loss or other issues.  This can range from an old 10/100 hub in a Gigabit network to old Cat-5 cables that were never replaced when you upgraded last.

    Router

    Not all routers are created equally.  Nor do they typically outright die when they are exhibiting problems.  An old, ailing router (or even a defective new one) my show no outward signs of packet loss and pass every speed test you throw at it.  Your router may be the source of the problem without you even knowing it.

    Many do not realize that NVidia has "approved" routers for use with Gamestream.  Check out the list here.

  • 15. Gamestream worked yesterday, but today my PC isn't showing up in Gamestream.
     

    Obviously try rebooting the Shield device and the PC.  Many times this will solve the issue.

    If you log into NVidia with a Google account, it seems like sometimes they "disconnect", even though you appear logged in via the Geforce Experience.

    Log out on the PC and log back in.  You'll probably get reauthenticated and the PC will show up again.

    If you've found another issue/solution like this, let us know.

  • 16. Will unlocking the bootloader or rooting my Shield void my warranty?
     

    Not necessarily; the wording in NVidia's own documentation says your warranty "may" be voided.  However, no one has ever stated publicly that they were denied warranty for bootloader/root issues.

    Note: NVidia's own instructions for rolling your device back to a previous, stable version tells you to unlock the bootloader.  I think that would make a good case to NVidia if you needed warranty work.

    NOTE: This information is not applicable to the new "K1" Shield Tablet - only the "OG" editions.

    Yes and no.  There have been no reported fires that I know of.  However;

    NVIDIA has announced a recall of its SHIELD tablets, sold between July 2014 and July 2015. NVIDIA has determined the battery in these tablets can overheat and pose a fire hazard. As part of this recall, NVIDIA will be replacing the tablet. <full story here>

    The above link will tell you everything you need to know about if you're affected and what to do if you are.

    To my knowledge, no Shield Tablet has "caught fire" or injured anyone.

  • 24. Since Android 6, I see a high battery drain for "Miscellaneous". What can I do?
     

    Update: The latest OTA should fix this as of 2016-02-19.

    Shield Tablet K1 with Android 6 (OTA v1.0) apparently has a known issue with "pegging" one of the CPUs at 100% after heavy use (hardcore gaming, etc). Once pegged, it isn't released until the tablet it powered off and back on (not a simple reboot).

    NVidia knows about this issue. The recent OTA update (v1.1) reputably was to solve this issue - but users continue to report it.  Note: As of 2016-02-06, V1.1 is currently recalled by Nvidia as they try to find more answers.

  • 25. Can I "unroot" and do I have to in order to get OTA updates?
     

    You don't have to unroot or wipe to apply OTA updates (at least so far; if you perform modifications beyond root, you are on your own), but OTA will wipe root and you'll have to re-establish it.

    Remember, when changing version of the OS (like Lollipop to Marshmallow) the exploits/methods of rooting will likely change.  If the OS that the OTA advances you to doesn't have a root method yet, it could be hours, days or even weeks before the ability to root will be available.  If root is super important, don't do OTAs to a new OS until the root method/tutorial is released.

    Easiest way to "unroot" is to simply restore to stock by using the steps at the bottom of my tutorials or: TV | Tablet | Portable.

    If your device won't update over OTA, back up your data and perform a restore to stock.  Don't panic - it is almost impossible to brick a Shield device.

    Technical Answer:

    You may also be able to simply flash the system partition to remove root.

  • 26. Why does my Shield Tablet's touch screen seem unresponsive when charging?
     

    From this post:

    I have the SHIELD Tablet, and like many of us had problems with a laggy touchscreen when certain chargers were used. It only happened by some, but not by all.

    Using a USB volt and current meter, I was able to identify the cause of the problem.

    First some technical background. USB ports and chargers always should give 5 volt. Small variances are allowed, and usually not a problem. Some chargers will drop the voltage a little under load, which also should not be a problem. The current that can be delivered is variable and depends on what the device needs and the charger can handle. Too heavy a charger does not matter, too light a charger only makes the device charge slower, but no technical problems should be caused.

    Now, I just yesterday received a new charger, and it has two ports, one for 1 amp of current, and one for 2.4. If the tablet is almost empty, it will try to draw about 1.7 Amps of current, and with the 2.4 amp charger, this will cause a drop from 5V to 4.7V. This also caused the touchscreen to lag.

    When I used the 1 amp port it could not charge as fast, but the voltage remained at 5 volt. Because of this the touchscreen did not lag.

    So basically, a charger that drops its voltage too much will make at least some touch screens of the nvidia SHIELD lag. the problem can be solved by taking a charger that does not drop its voltage under load, which in my experience means a less heavy charger then is needed for optimal charging. I recommend using two chargers, if you cannot find a heavy one that does not drop its voltage too much.

  • 27. When trying to root/flash/stock recover, I get “FAILED (command write failed (Unknown error))”
     

    Every time I've helped someone with this issue - it has been the USB cable.

    All USB cables are not created equal.  Cables that come with your phone are typically for both CHARGING and for DATA.  These are usually higher quality and should do the job of performing rooting/flashing on your Shield device.

    Cables that come with external batteries/powerbanks, etc. are usually cheap and designed for CHARGING only.  They may work "ok" for data, but these may fail when trying to write low level to the Shield device.

    Along with quality, LENGTH of the cable can make a difference.  I helped one person with a FIFTY foot USB cable - another with 6 cables daisy-chained together.  Both received this error message when trying to flash.

    Short, high quality built-for-data USB cables are the solution.

    Finally, make sure you're using a high-quality USB port; avoid hubs and the front ports on the PC unless you've used them successfully before.  Use the back "motherboard" ports.

  • 8. Is it possible to sideload Android apps without rooting, etc?
     

    Yes.  You’ll need to enable UNKNOWN SOURCES (and probably disable VERIFY APPS) and you’ll need some way of getting to the APK files to the box.

    To download APKs from the store, try this website.  Drop the APK files onto a microSD or flash drive and plug them into the Shield.

    You’ll need a file manager to access the APKs.  AnExplorer File Manager can be downloaded on the Shield from the Google Play store (or do it from the web).

  • 16. How do I enter Fastboot on the New Shield TV 2017?
     

    Via XDA:

    There are two ways to access fast boot. The first way to access fast boot mode,

    1. Buy a male to male USB 3 cable, & plug it into the USB port furthest away from the hdmi port.
    2. In settings of the shield, go to storage.
    3. Enable USB transfer
    4. In settings go to about, then build version.
    5. Click on build version 5 times.
    6. Under settings, go to developer options.
    7. Enable USB debugging.
    8. Make sure you have the latest drivers installed from Nvidias website.
    9. Download ADB Command prompt/fastboot
    10. Type "adb devices"
    11. You may get a prompt on your shield about allowing debugging, if so make sure you allow it.
    12. Type "adb devices" again if a device shows up then great! move on to the next step.
    13. Type "adb reboot bootloader"

    The second way of getting into fastboot mode, is the following

    1. Unplug your power cable from the device.
    2. Plug in your Shield game controller in the usb closest to the hdmi port.
    3. Hold down buttons A & B.
    4. While holding down the two buttons, put in your power cable.
    5. Keep holding down the buttons.
    6. If all done correctly you should see the fast boot menu now on your screen.

  • 17. What cable do I need for ADB/PC access to the New Shield TV 2017?
     

    With the microUSB female plug gone, you will need a rather special cable; a USB3.0 Type A Male to USB3.0 Type A Male cable.  You'll use this in the USB port farthest from the HDMI port.  The USB port also has to be toggled to support ADB/USB operations within the SETTINGS/Storage and Reset section of the Android TV OS.

    Here are a couple of cable choices from Amazon: 3 Feet6 Feet | 10 Feet (all support Prime shipping)

  • 1. What is Folder Mount, why do I need it and how does it work?
     

    Note: Adoptive Storage in Android 6.0 sort of removes the need for this.  Check out my article on Adoptive Storage to better understand.

    Some games will not allow you to move them to your external SD card.  This takes its toll on the free space on your internal memory and with huge games weighing in at 2GB or more, those of us with mere 16GB tablets need the ability to move games (at least their big bulky data files) to our SD card.

    Folder Mount is an app (requires root) that allows you to "move" anything in your internal memory to your SD card.

    It works by creating a "link" between your internal memory and your SD card known as a symbolic link.  This "tricks" the operating system into routing all its calls for a folder internally to an SD card directory.

    Let's say you install A Really Cool Game that downloads 800MB of data to your internal storage located at:

    <internal memory>Androidobbcom.company.reallycoolgame

    Folder Mount will allow you to create a "mount" point between <internal memory>Androidobbcom.company.reallycoolgame and <external SD Card>Androidobbcom.company.reallycoolgame

    From that point forward, all calls (load, save, whatever) that are made to <internal memory>Androidobbcom.company.reallycoolgame will automatically jump to the SD card's location.

    Part of this process is moving the contents of the internal folder to the SD card equivalent.  Fortunately, Folder Mount will do that for you - and even move the content back if you decide you don't want that link anymore.  If you do not allow Folder Mount to do this for you, you will have to move the files yourself - while the mount point is NOT active.  If this isn't done, you can easily end up with TWO copies of the same game data (even if you can't see it - remember, the OS is completely fooled while the mount point is active - even file managers won't know the difference) and that doesn't solve your storage problem.

    The app does require purchase if you have more than a few links.  I do NOT recommend creating top level links like Androidobb or Androiddata to the SD card.  While it is a little more work to do it one folder at a time, you will run into a lot less trouble.

    Remember, your SD card is slower than internal memory (in some cases many times slower) and games may take longer to load, stutter during play or have other undesired results.  You'll want the fastest, best SD card you can afford if you plan to use this process for these types of games.

  • 2. Why can't I write to my SD card with {insert application here}
     

    Note: Android 6.0 (aka Android Marshmallow) can affect how SD card is accessed.  Read my article on Adoptive Storage for more information.

    Since Android Kit Kat, Google has locked down security on the SD card.  In Kit Kat, a program could only WRITE to a folder within the /Android/Data/ folder named the same as the package name of the app (i.e. com.foo.packagename).  This ensures that an app cannot get to or modify other data on the SD Card.  To get around this, root users could use a tool like SDFix to remove this restriction and make the SD Card read/write for all apps.  Read access was available across the entire SD card.

    The same holds true with Lollipop.  All apps can access the SD card for reading, but only the designated folder for writing.

    Lollipop, however, allows for "elevated privileges" to apps that are code-compliant with Lollipop and are granted this access by the end user.  This does not require root access.  When an app is compliant, it will ask the user to select a folder for access.  If you choose the root folder of the SD card, the app will have full privileges to read and write.  One such file manager is ES File Explorer.  You can educate yourself more here.

    MOST apps do not include Lollipop support for this level of access.  If your favorite application cannot access the SD card to your liking, I recommend rooting and using SDFix.  Your only other choice is to write the developer and ask for Lollipop support.

    With Android Marshmallow, SDFix no longer works.

  • 6. I’m having general issues accessing my SD card/external storage. What else could be wrong?
     

    Note: Android 6.0 (aka Android Marshmallow) can affect how SD card is accessed.  Read my article on Adoptive Storage for more information.

    There are reports that if your SD card is formatted with ExFAT that you can have issues with it on the Shield Tablet.  Using a computer, copy the files off the SD card, reformat it using NTFS, then restore your files.

    There is also word out there that if the SD card partition isn't named (i.e. it is blank), Lollipop will deny access to it.  Naming it may also solve your problem.

    Your other option is to get another SD card, format it with the Shield Tablet - then use a computer to copy the files off your old SD card to your new one.

    If you have a large external drive, it may have been made with a GPT partition instead of an MBR partition.  Visit this site to better understand the differences.  If you have 2TB or less, you can use MBR in a single partition.  If you have a bigger drive, you may have to use multiple MBR partitions.

  • 7. Some games won't install to the SD card. Anything I can do about this?
     

    Many games support installing to the SD card already.  For those that do not have built-in support, you can use Folder Mount or Link2SD.  These  applications require root access.

    Upgrading to Android 6.0 (aka Marshmallow) on K1 (soon on Shield Android TV) will allow you to adopt your SD card as internal memory.  See my article on the subject.

    I have seen some of the problems where u cant move stuff you should format in a pc and name the allocation or what ever it is in the format option

  2. damien09 says:

    For the people who don’t root should add about doing a PC format and nameing it because without that it wouldn’t even let me rename or move files that should be able to

  3. Zyad Madkour says:

    I got an issue with the USB connection to PC….first it was connecting properly, now it’s not connecting, it doesn’t even recognise connecting to a device…. I can’t recall whether it’s before the lollipop upgrade or after it

  4. Zyad Madkour says:

    even though it’s the original cable and it was working before, it may no be working?
    also it’s detecting the power

    • Wouldn’t hurt to try … But yes, you can have power without connectivity with a faulty cable.

      When you plug it in, does your PC make some sort of a sound like when you plug in a mouse or keyboard? If so, do you still get the sound when plugging in the Tablet?

      After you plug it in, do you get something in the notification shade of the Tablet? Connected as Installer, Connected as Media Device, etc.?

  5. Zyad Madkour says:

    no sound from the PC and no notification from the tablet, there was a sound and notification before though.
    I tried 3 cables with 2 PCs, and nth

  6. Zyad Madkour says:

    it makes no change in the device manager when I plug it in, and I just rebooted the tablet and the PC

  7. Zyad Madkour says:

    it doesn’t sense its storage

    • Once you’re in installer mode, you should see a notification on the tablet that says CONNECTED AS AN INSTALLER. Now tap that and change it to a Media or Camera (I’m doing this blind here – I don’t have my shield on me).

  8. Zyad Madkour says:

    it only has USB debugging connected (Touch to Disable USB debugging) also, there’s no settings option for the USB connection outside the developer options, IDK whether it’s just the lollipop or what

  9. Zyad Madkour says:

    it’s solved with a factory reset 🙂
    thank you, I appreciate your help

  10. peter says:

    I have the same problem with connecting shield tablet to win7. After resetting to factory default, my win7 recognizes the tablet, but after installing lollipop or updating the tablet, it doesn’t work anymore. I sometimes hear a sound from windows, but no pop up window from PC or no menu from tablet to choose as media or camera. I even went to Microsoft website to download the driver/software, but still doesn’t work.

  11. peter says:

    I actually found the answer.
    1. Go to your shield tablet settings
    2. Click on storage
    3. Then option ,(3 dots in the upper right corner)
    ,4. Checkmark enable mtp (media transfer protocol)
    5. That’s it.

    That’s what I’ve been looking for

  12. peter says:

    Minor correction:

    after clicking 3dots, tab/select the “USB computer connection” choice, then checkmark “mtp enable”.

  13. Drew says:

    I can’t get my Shield to go into fastboot mode. I can reset it into the bootloader using minimal ADB from my computer, but then when I select fastboot from the options on the tablet and hit the power button, the screen goes black for a second and then goes right back to the bootloader screen.
