Solved! I have a Cambridge Sciences tablet that is stuck showing the word Android at boot up.

I have tried a hard reset ie holding the vol up and on button together and after the logo i get a large android green figure lying on ots back with its tummy open showing a red triangle with a black exclamation mark. I cant do anything else after this and after a while it goes back to its boot up and sits there with the word android waving but going nowhere. Is there anything else I can do to try and revive it?

If a factory reset fails you can try looking for a stock ROM for the device and load it from a computer with USB connection. https://www.droidthunder.com/flash-custom-rom-zip-adb-sideload/

That thing had some bad reviews, is no longer around, not a good sign of quality, very likely something on the system board died, maybe the memory/storage.
