Please check the label on the bottom of your X7 (if there is one). Some X7 devices will have a direct reference to one of the variations listed above. Please post a thread if you're not certain or there isn't anything obvious..
You will need the drivers and a program to flash your X7/X7 Ultimate from your Windows PC. They are available from https://1drv.ms/u/s!AlRdlhGu3fjihlnllfEYxvFaIuTE and https://1drv.ms/u/s!AlRdlhGu3fjihlit4Zg8z6z3vL44 respectively.
Extract (using 7-zip (free), WinZip, WinRAR or even Windows built-in utility, ) the contents of RK Release_DriverAssistant.zip, and store it somewhere you can easily remember. Run the "DriverInstall" program and follow the onscreen instructions.
Now extract RKBatchTool1_7.zip to a folder, and again make sure you remember where it has been placed!
You will need a standard microUSB cable to connect your PC to your X7/X7 Ultimate.
With the power cable removed from your X7, please:
Locate the reset switch found on the bottom of your X7 and hold it down. Please don't release it until told to.
Connect your microUSB cable, one end into your PC as normal, the other into the USB OTG socket at the rear of your X7. You can now reconnect the power cable.
Once your PC notices there is new hardware attached, you can let go of the reset switch.
Once the driver installation is complete, please open the RKBatchTool folder you previously extracted, and run RKBatchTool--1.7.exe . If the drivers have installed correctly, then under Connected Devices, "1" should be green.
If that doesn't happen, and you're using a USB hub to connect the X7, try a direct connection to one of your computer's USB sockets, and if you have a choice, select a USB2 (rather than USB3) socket.
Click the ... button at the top right corner, and point it to the folder you downloaded the large firmware file to earlier. Select the IMG file and click the Restore button, and wait until the process completes.
Once the firmware flash has completed, you can disconnect it from your PC. The first time you turn the X7 on you will find it takes a bit longer than usual to boot up. If any set up screens are presented, complete them and select which launcher you want to use, if asked. Once you reach the Android launcher homescreen, please wait 20 minutes for applications to complete installing.
