If you get this iPad back to an operational condition, what were you planning to do with this over 10-year old iPad?

Apple ended support for all 8-10-year old iOS devices nearly 5 years, ago, in 2016.

Third party app developers abandoned and stopped supporting these 8-10-year old iOS devices nearly 3 years, ago, in 2018.

There are, virtually, NO MORE third party apps available from the iOS App Store, any longer!

Third party compatible apps for such old devices are few and far between, now, in 2021.

This includes apps for both iOS 9 AND iOS 10 devices!

AND, NO WAY to initially install any older, compatible, third party apps into this old iPad.

NO MORE SUPPORT! NO MORE APPS!

I do not think you should put any efforts into trying to re-use/resurrect this very old iPad.
