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

Aug 1, 2021
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?
