The Super Villain Guide to Rooting Your ZTE v768 Concord

he ZTE Concord is an affordable handset at $60 for entry-level smartphone users. I followed these simple steps for an unlocked T-Mobile ZTE Concord v768 I picked up off ebay. The specs for the phone I use with Solavei  are Android version 2.3.7 Build number V768V1.0.0B08. The whole process took less than ten minutes.
Of course, this guide comes with the standard “At Your Own Risk” disclaimers.  Be warned, rooting your phone voids the warranty.
They say if you root your phone it is “Modifying” it hence voiding the warranty. Just being able to remove their unneeded Bloatware & Junkware on your phone is apparently bad. In the 21st Century, having knowledge and ability is frowned upon.
Go figure.
So if you want to make the leap into the abyss with me, let us get to business.

Rooting Your Phone

Apps you will need to download from the Google Play Store:
  • Root Checker – by joeykrim -  This application will test the device for root access using a very simple, quick and reliable method to check for root access.

Reboot into recovery mode by first holding  down the Volume Down button and then holding down simultaneously the Power button for 30 seconds until the Android with the Triangle & Exclamation appears.   The Android with the Triangle & Exclamation will appear AFTER the Green Android that is by himself.  If for some reason, you CANNOT boot into recovery, then try a FACTORY RESET (see special notes below) and try again.
  3.  At the screen showing the Android with the Triangle & Exclamation, Press the HOME button.
  4. Scroll to your second option “Apply update from sdcard”, navigating with the volume buttons and press the Menu key
