Easy Root & txPower fix on Zenithink ZT-180

There are a lot of people who are unfamiliar with Android and the SDK so I thought I would show you the easy way to gain root access and apply the txpower fix. If you don’t already know, the txpower fix changes the txpower value from 100 to 20 which gives you better wifi performance plus helps with temperature problems. It should also slightly increase battery life.

Follow these steps below:



Step 1: Download UniversalAndroot – This application is very easy to use and will root your zt-180 in about 20 seconds. Download to a USB flash drive and install via file manager or install directly from your tablet by clicking on the link. Once installed open the app and click root.

Step 2:  Download SuperUser – (There is no need to download this file anymore as it’s installed as part of UniversalAndroot). This application gives a program permission to run root functions. There is no need to open the app once it’s installed.

Step 3:  Download RootExplorer – This is the ultimate file manager giving you complete read/write access to Android’s file system. Install and then run. Upon opening RootExplorer you will get a superuser popup – tick the Remember box and then click on Allow.

Step 4:  Once RootExplorer is open, navigate to /etc/Wireless/RT2870/ and you should see a file called RT2870STA.dat


Step 5: Above that file, select the grey button that says Mount R/W. It should now say Mount R/O

Step 6:  Press down on file RT2870STA.dat until you get the menu popup. Now select Open in Text Editor down the bottom in that list of options

Step 7:  On the 12th line down where it says TxPower=100, change the value of 100 to 20.

Step 8:  Now click on the Home button and then click Yes to save changes.
