iPhone 5 won't turn on at all
So i have a quick question. Yesterday i purchased an iPhone 5 that completely doesn't work at all. I've tried plugging it into the charger (still not turning on), i've tried forcing it into DFU mode (that didn't work either), i've tried plugging into my laptop and that didn't work either. When i got the phone yesterday the screen was completely cracked so i've ordered a new replacement screen ,but I'm worried this isn't the only issue as i was waiting for it to vibrate or something indicating it's just the screen that needs replacing. If the screen replacement doesn't fix it, what does everyone advise I do? Get a new battery or something?
Any help would be greatly appreciated.
Is dit een goede vraag?
