By a mistake by himself it seems the iPad was “infected”. He already changed his Apple ID password in all his devices (same as emails)
By security reasons since that incident He has the iPad turned off. He is concerned if it is turned on again the “bad program” starts do its job again.
He is not sure what is the current iOS. He doesn’t remember if he did an upgrade of the iOS itself. Well the hardware is in perfect conditions.
Question
How to re-install the latest iOS suitable for an iPad Model A1458?
But - given this device is circa 2012 - you’re not going to have much luck getting an iOS update for it… it was EOL (end of life) years ago… Having said that - Apple are better than many other tablet vendors - I’m still getting updates for my 2017 iPad pro, and circa 2019 iPad Mini 6th gen…
I’ve had two Galaxy tablets (note pro series) - both of them were stuck on Android 4! No official way to get anything later… they’re rubbish… landfill… The 2nd one a 12.2" pro actually got itself into a “boot loop” - i.e. it would power on - then reboot… ad nauseam…
Apple crap all over Samsung for nearly everything…
My iPad pro 12.9" (2017 model, purchased in 2018) is STILL getting updates from Apple!
Having said the above - I don’t like iPhones or the iOS ecosystem - so I use Android for phone - and - my current one is a Samsung Galaxy S9+ (2019) - which - was End Of Life in 2022! that’s pathetic - a “flagship” device only getting 3 years of support? And it’s stuck on Android 10 and I’m missing out on a heap of features in Android 11 and 12… But it “works” anyway - I’ve been looking around for a replacement - but really don’t “need” to…
I kinda hate nearly everything Samsung do - except maybe for DeX… I think they’re better at making dumb devices than being “smart”… I have 15 year old Samsung LCD monitors that still work…
