How to update IOS10 to Ipad with IOS9.3.5 A1432
iPad mini (1st generation)
An A1432 iPad is a 2012, 1st gen iPad Mini.
That year and model iPad can only support iOS 9.3.5 and NO farther.
Also, that iPad is very old and very obsolete!
There are little to no third party apps or services that support such old iOS devices, any longer.
Sorry.
