When I try to turn my tablet on it says “installing system update” and then “Error!” .Why is this happening and how can I fix this?

Thanks

Your Android version is probably partially updated and installed on the phone and is now considered unknown, or you may have rooted your phone and deleted the entire ROM after the first reset. In general, you have to install the phone ROM manually, ie with the mute and volume buttons on the phone, and set it up from there, or install the new ROM through the computer.

There are many things that could be wrong here. However, resetting (to factory settings) the device should help narrow it down. i had this issue in 2020 and that oughta fix it. did not get to know specifically what was wrong though...:(
