What solutions do I have if my SURFTAB THEATRE L15 is not responding?  

If you can no longer use the SURFTAB THEATRE L15 or if the device no longer responds to input, reset the device. Press and hold down the on/off button until the device switches off. Wait for about 20 seconds and then turn the device on normally.

What should I do if my SURFTAB THEATRE L15 is not recognized by the Android Debug Bridge (ADB)?  

Firstly, make sure that the USB debugging mode is activated in the SURFTAB THEATRE L15 developer options. If the developer options are not displayed, go to "Settings" -> "About Tablet" and tap "Build number" until "Developer options" appears under "System" (under Android™ 5.1.1 as a new option in "Settings"). Ensure that you have already installed and configured the latest Android SDK.


For Windows:
Go to the Windows device manager and check whether there is a device marked with a yellow exclamation mark (!) that corresponds to your tablet. Right click this entry and select "Properties". In the "Driver" tab, click "Update driver's software". In the window that follows, select the option "Browse my computer for driver software" and enter the path where the unzipped TREKSTOR "android_winusb" driver is located. If you receive a message during installation that prompts you to not install this driver, confirm with "Install this driver software".


Windows and MAC OS X:
It is now necessary to configure the ADB for the TREKSTOR tablet. You must add the TrekStor Vendor-ID (0x1e68) to the "adb_usb.ini" file in the hidden ".android" folder. To do so, proceed as follows:


1. Open the command prompt and enter the command "echo 0x1e68 >> $HOME/.android/adb_usb.ini".
2. Now check whether the SURFTAB THEATRE L15 has been recognised by opening "cmd.exe" and entering the commands "adb kill-server" and "adb devices" in succession.


1. Open the terminal window and enter the command "echo 0x1e68 >> $HOME/.android/adb_usb.ini".
