What if you do not have access to connect to a computer?

My phone is stuck on the apple. -:0 Its an iPhone 8. I’ve tried pressing volume bars and holding power bar. No change. Flickering a bit. Do I need to connect to a computer for the phone to move past the apple? Can it be connected to an iPad? Not even sure how I’d do that. Do I need to connect to MY computer? Or can it be ANY apple computer? Thanks!

Does it need to be MY Mac or can it be any Mac?

Can be any Mac computer or does it need to be mine?
