ASUS TF300T 4.2.1 ROOT

admin

Smile [JB ROOT] motochopper works! (Root JB 4.1.1 & 4.2.1 with locked bootloader!)
I got my TF300T with JB preinstalled. So I've never been able to root until today. (I didn't want to unlock my bootloader.)

Backup your root with Voodoo OTA Rootkeeper!!!

This does not touch your bootloader.

Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
Now scroll to the bottom and tap “About phone” or “About tablet”.

Make sure you tap seven times. If you see a “You are now a developer!” message pop up, then you know you have done it correctly.

% g( k  ~; `. b5 _$ ?5 gDone! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.

我现在的版本是4.2.1 （JOP40D.CN-epad-10.6.1.27.5-20130902), 在内核版本上边点七次将会自动在左边主菜单出现“开发者选项”菜单 然后点进去打开USB调试  选项就可以了 然后下载motochopper，解压到电脑，在平板上开启开发者选项后，最后执行run.bat，然后按提示随便敲两次键盘平板就重启OK了
