A family member of mine was having problems with a cheap Chinese 7 inch Android tablet PC bought a couple of years ago that came with a Wondermedia 8850 chipset. He was having problems with it connecting to WIFI and it was running slow.The tablet originally came with Android 4.0.3 Ice cream sandwich installed so I searched to see if I could find a newer updated firmware ROM. Ideally I wanted a Kitkat or Mashmallow firmware but Jellybean 4.1.1 was the best I could find from this posting on Techknow.one the download link for the ROM file was hosted on mediafire and appears to be dead and I was struggling to find a valid link on other sites.
In the end I did manage to download the Universal Uberoid firmware for WM8850 and thought I would upload the ROM here and offer to share the link for others who might be struggling to get a download from Uberoid 4.1.1.To be able to flash the firmware on your Wondermedia 8850 tablet you will need access to a PC and also a SD memory card.

Once you have extracted all the files you will need to copy the included APK app (com.hch.techknow.toolkit.22apr2013-2.apk) to an SD card or directly onto your WM8850 tablet and install the application.

You will need to ensure that your WM8850 tablet is set to allow install of apps from unknown sources by going to settings security and ticking unknown sources.3. After the app has been installed run the the Analyzer which will show you the model info for your Wm8850 device, it will also copy a file called model.txt on your SD card (make sure you have inserted an SD card before running the analyzer app for it to be able to write too)4.
