I have a Mac so I wasn't able to use the RKBatchTool. Luckily it was really easy to soft root my T62D.
Soft root process
I updated to the latest firmware, T62D-160202 (
https://drive.google.com/folderview?...FRSaWU5TUF5aXM), and then downloaded the KingRoot apk (
http://www.kingroot.net/) and installed it on the T62. Then all I had to do was run it and do the one-click root. An alternative I didn't try is the 360Root app which some users on Chinese forums seemed to prefer.
After rooting, I installed RootChecker to make sure it worked and then installed SuperSu and the Xposed framework so I could re-map the hardware keys. I also granted root permission to ES File Explorer and changed my screensaver.
Changing the hardware keys so I can use long presses for Home, Recent Apps, and Screenshots was the single most useful thing about rooting for me. Now I can leave the status bar hidden and use it in full screen all the time.
Play store questions
I'm not sure what the best method is to install the Play Store without using the RKBatchTool. I've flashed gapps on phones before, but there seems to be no way to boot the T62 into recovery to do this (I tried using a few apps to boot into recovery but all of them just gave me the sad Android screen). Possible alternative methods include:
1) A gapps installer app (but these seem a little sketchy)
2) Manually installing the gapp apks (from the T6x_Ereader_toolsKit. This seems to require some minor fiddling with the root directories.
3) using ADB commands on a Mac.
Has anyone tried one of these methods?
I haven't pursued it further because I can do almost everything I need without the Play store. I can get apk files from the GoodEReader store or by downloading from the Play Store through this site: (
