Tutorial: Root Shield Portable (Non-Lollipop)

You can root “on device” or using a PC with ADB and drivers, etc.  We’ll be discussing the “on device” method which does not require a PC or anything other than the device itself and some special software. Note: I did not develop any of these tools nor am I responsible for any of the methodologies.  I’m simply consolidating the information here and will include links to the original information when possible.  Some of the process I wrote on my own.

Root On-Device (Jellybean)

If you just bought a Shield new from Gamestop or another vendor, you probably have Android Jellybean installed on it.  You will use this section.

  1. On your Shield, download TowelRoot (1162 downloads) (original site).
  2. Install TowelRoot on your Shield.  Note: You must disable VERIFY APPS and enable UNKNOWN SOURCES in order to install this.
  3. Run TowelRoot.  If all goes well, you’ll see a MAKE IT RAIN button.  Tap it.
  4. TowelRoot should report back that your device is rooted.
  5. You’re done! Install your favorite root apps like AdAway or Titanium Backup.

Root On-Device (Kit Kat)

If you’ve done pretty much any update to your Shield, you’re running Kit Kat and will need to use this section. Note: This still works with Update 5 that was released August 2014.

  1. On your Shield, download TowelRoot (832 downloads) . Note: This file may trip your anti-virus software.  It is safe. For some reason, v3 doesn’t seem to work on Kit Kat (it will tell you that the device isn’t supported).
  2. Install TowelRoot on your Shield. Note: You must disable VERIFY APPS and enable UNKNOWN SOURCES in order to install this.
  3. Run TowelRoot and click the MAKE IT RAIN button.  Do not panic if the Shield doesn’t behave as the onscreen instructions say it should.
  4. Wait about 15 seconds.  If the Shield doesn’t reboot, manually reboot the Shield.
  5. Once you’re back up, install SuperSU from the Google Play Store.  Follow the instructions.  Update the Binary if required.  (Select NORMAL as the method)
  6. That’s it.  You’re done.  Your first step should be the NextApp SD Card Fix app.  Other useful root tools include AdAway and Titanium Backup.  To learn more about what root can do, check out my article here.

    Towelroot states the shield isn’t supported and fails to work therefore I can’t get access to write to SD card at all

  2. Hi,

    I have android 5.0.1 and used tr.apk (v3). I got : this phone is currently not supported.

    So I changed modstring 1337 0 0 4 1, but no luck. What modstring should I use?

    After installing towelroot and rebooting, playstore doesn’t work through the app, chrome or browser, google search doesn’t work most of the time except to find msn, which allows me to use bing, but still doesn’t load playstore. My games and other apps work though. I uninstalled towellroot and now my device is fine. Help?

    • Positive you’re using the right version? I got it installed on mine and everything is peachy.

        I used your link, downloaded v1. It installed and opened seemingly fine, clicked let it ra1n, it did not reboot so I turned it off and on. Then went to use PlayStore to download SuperSU and no luck, Chrome no luck, browser no luck. I uninstalled tr1 and then turned off and on and everything was back to normal. So I tried again, waited a bit longer before turning of and on, same issue, uninstalled, turned off and on, and now, it still doesn’t work. So now I don’t know what to do.

          Basically nothing Google works at all, gmail, google search in chrome or browser, PlayStore etc, but bing works just fine and so do my non Google email accounts and my games and apps already installed.

    Update: So, I backed up my data, reset to factory default, and… had the same issue. Did some research online, went to my wifi settings, held down on my network, tapped “modify network” went to proxy, it said manual, I changed it to none, everything is fine now :/ I had AdBlocker which required certain proxy settings so mabye that had something to do with it? I don’t know.

    I will try towelroot again once Google has finished loading my back up. I hope this works as not being able to fully use the sdcard almost defeats the purpose of having this device in the first place. I will update my results.

    Shane, great writeup! Was able to root my Shield Portable with KitKat very easily using your instructions.
    I am experiencing “insufficient space” warnings when updating apps/games. I have a 32GB SD card that has plenty of space, but even though the app says its on external storage in app manager, it doesn’t seem to update.
    I I tried using the SDFix app, but it did not seem to fix the issue.
    Any ideas?

    That towelroot link triggers the antivirus saying it is malware. Is it or is it a false positive?
