Nexus Root Toolkit is a really handy Software and a powerhouse too, here are the FAQs and the questions I had in my mind when I first used the Nexus Root Toolkit.

Q) I get a hash check mismatch, what should I do?

  • Answer: Press the “Continue” button, a new popup will appear with a download link given below just use that link to download the file and just import it into the toolkit.

Q) I cannot find my Build Number in the Dropdown, what should I do?

  • Answer: If you cannot find your build number then the best case would be to click on “Auto Detect + Build “Button. If you do not want to do that then you could enter your device manually and just click on Android *.*.* – Any Build.

Q) My device does not get recognized by Nexus Root Toolkit, what should I do?

  • Answer: You need to download and install your Device’s ADB and Fastboot drivers.

Q) How does Nexus Root Toolkit root my device, how does this Software Work?

  • Answer: This Software gives u a friendly and easy to use UI which u can interact with petty easily but at the back end all the hectic ADB commands get run automatically for you, so Nexus Root Toolkit uses the traditional ADB command prompt way to run the Scripts but everything gets done by the Software Itself so it is better than running the ADB commands on your command prompt manually.

Q) How do I enable USB debugging on android 4.2.* and above?

Answer: The “Developer Options” menu item on 4.2.* and above is hidden.

  1. Go to Settings -> About Phone.
  2. Go to “Build Number” at the end of the Scroll list.
  3. Tap on “Build Number” repeatedly (7 times). On your third tap, you should see a message indicating that you only have 4 more taps to go to ‘become a developer’.
  4. Continue: 4 more taps.
  5. Hooray, you are now a ‘Developer’, go back to the Setting page.
  6. You should see the Developer Options menu item in your setting list now.
  7. Open Developer Options and check USB debugging > Ok.

Q) I am running a Custom ROM, what build do I select?

  • Answer: If you are running a Custom ROM then the best case would be to click on “Auto Detect + Build “Button. If you do not want to do that then you could enter your device manually and just click on Android *.*.* – Any Build.

Q) Will OTA Updates work after I Unlock and Root?

  • Answer: OTA (Over The Air) Updates are Stock in Nature and they are rolled out by google if you are running a stock android or rolled out by your phones manufactures if they are not running a Stock android e.g. Touch wiz Android updates are rolled out by Samsung. If you make any system level modifications then OTA will not work because the process checks the entire system partitions. If even a small file is changed or added the OTA will fail. Since rooting installs Superuser as a system app and SU binaries to the system partition it inherently breaks OTA.

Q) So how should you update a rooted device?

  • First, wait for the Official Factory Images to be released by Google.
  1. Backup your apps + data because it’s a good habit.
  2. Use “Flash Stock + Unroot” and check “Force Flash” and “No-wipe mode” (to avoid a data wipe).

That’s it.  Afterwards, you can re-root.
