IPad 2 Update and Restore Problem 4.3.x to iOS 9.0.2?

I'm trying to use my old iPad 2 and when i checked it still had the iOS 4.3.x (unsure what version of 4.3 it was), so when I plugged it in my computer iTunes said it can be updated to iOS 9.0.2, so i downloaded it and everything went accordingly, but suddenly when trying to update it says Unknown Error Code (9), now my iPad 2's stuck in recovery mode, have already tried the following:

a) Restarting both my Windows computer and iPad 2
b) Tried using a Mac with a different downloaded update
c) Changed ports of my computer in which my iPad was connected to

and none of these have worked so far.

Anyone know how to fix the recovery mode loop or if it is even possible to update 4.3.x to 9.0.2?
