Q: How to downgrade iPad 2 Wifi from IOS8.3to IOS 8.2?

Writing an firmware "upgrade" for my iPad that makes it useless as a navigation tool with external GPS: my one and only use for my iPad is one thing. But then preventing reinstallation of the former firmware is hefty. It makes me feel like these flaws were built in on purpose. Which purpose we all can only guess. As an Apple user since the Apple II  I should know better and have gotten accustomed to Apples well known downward incompatibility.

PS: No GPS signal delivered to navi- programs with "Dual150®" and other external devices.

iPad 2, iOS 8.3, MacBookAir MacOS X.10.3
