If you are on a Mac, you may need to this first: https://wiki.umbc.edu/pages/viewpage.action?pageId=31919091
Please download AndroidTV_Wonder_WonderPlus_Lolipop_7.0.1-UNZIP_THIS_FOLDER.zip from https://mega.nz/#F!oFN3gDiQ!vlGC5PpdE0KeNwSPY5YIHg . Once the page loads up, right click on the filename and select DOWNLOAD , then STANDARD DOWNLOAD. It will take a while, once the file has downloaded, extract it please. If you're on a Windows PC, you should be able to do this with a right click, then select EXTRACT ALL and follow the on screen instructions.
The 3 extracted files should be:
AndroidTV_Wonder_WonderPlus_Lolipop_7.0.zip
factory_update_param.aml
recovery.img
Now connect a USB memory stick (with at least 700Mb free) to your PC. It should be formatted to FAT or FAT32 - if you're not sure which was originally used, right click the drive in Windows and select Properties. It should mention FAT, FAT32 or NTFS as the file system. If it is NTFS right now, copy the files you want to keep to somewhere on your hard drive, then right click the USB drive again and select Format this time. Check that FAT or FAT32 is selected.
Copy the three files listed above (NOT the one with "UNZIP_THIS_FOLDER" in the filename please) to the root of your USB device (that is to say, please don't put them in a folder on the USB drive, just straight onto the first area of the drive.
Now right click the USB drive again and select Eject. The PC will tell you when it is safe to physically remove the drive.
Next, with the Wonder Plus turned off and the power lead disconnected, connect the USB drive to one of the USB sockets. There should be a small hole underneath the Ethernet socket on the back, you will probably find a toothpick or thin paperclip can fit in the hole. If you push down, you'll feel some resistance as a hidden switch is pressed down. Please don't release this switch for some time yet.
With this switch still held down, reconnect the power lead to the Wonder Plus and turn it on. Don't release the switch yet.
Your TV should show an Android/robot image to indicate that a system update is taking place - you can release the switch now.
Once the process completes, allow the device to boot up, it will probably take longer than normal. Once you can see the homescreen, please DON'T POWER OFF/REBOOT the device for 20 minutes. After that, you should be ready to use it as normal. If Kodi 16.1 is installed and you want 17.3, open the list of installed applications and open Google's Play Store. After signing in, search for Kodi and click the Update button. If you are only offered Uninstall or Open, please select uninstall, THEN click the Install button.
