We here at TAS (now it is cyanogenmods.org) have compiled what we consider to be the best ZTE Merit root guides available. Some of these Android rooting guides come directly from us while others come from sites that we believe make the cut for a good quality guide to getting your android ZTE Merit rooted. Rooting is a means to grant you, the end user, increased access or permissions to your device. Not much different than administrator access in windows operating system, root access allows you to perform functions that your device is set up not to allow you to do. You can run more apps like titanium backup. You may have noticed some apps on the Google play store require root access. Install custom ROMs or kernels in order to take customizing your phone to next level and add some extra features!
How to root the ZTE Merit:
This method does NOT workanymore.
Please check out these forums for info as to what has been tested already. As of yet, no one has been able to successfully root the Merit (Z990G). The ZTE Avail (Z990), however, has been rooted. Many confuse the ZTE Avail and the ZTE Merit, as they are similar in design, but the Avail runs Android 2.3.4 while the Merit runs 2.3.5.
