Apps organized in groups lost - fed up with Apple

Restore your phone from the last backup you made before you reset the home screen.

If you reset your Homescreen (Settings>General>Reset>Reset Homscreen) that would removed the folders. Or, if you enabled/disabled Restrictions for apps (Settings>General>Restrictions), that would also remove them. Just so you know.

I AM FURIOUS!

That seems to have nothing to do with your original question, in which you didn't mention you had any issues other than you'd lost your folders.

Why are you not able to deactivate Find My iPhone? If you forgot your Apple ID passcode, start here:

This makes no sense. As Idris points out, this has absolutely nothing to do with your question.

What "vicious cercle[sic]" are ty locked in? How can you have put your phone into recovery mode if your phone is not accessible? If you don't have physical possession of the phone, then of course it's not accessible. If you do, then how, exactly, is it "not accessible"?

Calm down and actually explain your problem in a coherent way instead of going off the deep end.

That's pretty much physically impossible. It takes effort to get the device set so that you can install iOS beta builds.

You can't return to the older version of iOS.

Already fed up with tha battery issue.

You are bringing up a new problem in every post. Perhaps you should start at the beginning.

Sounds like you should have stuck to a flip-phone. Go to SETTINGS/iTUNES & APP STORES.....check your settings ( see if you have "OFFLOAD UNUSED APPS" on.
