How do I remove update 8.0.01 that caused so much havac lat week?

[iMore Question]

Face opens and returns back to home screen typing is delayed and phone freezes up . Other apps won't open and even trying to submit this question was shut down. iCloud and face book under settings are "grayed " or ghostlike. HELP
