iPhone 8 in infinite bootloop tried everything and EVERYTHING

So after i updated my iphone 8 to ios 12.2, my phone started going on an infinite bootloop i tried everything dfu mode recovery mode no avail. sometimes when it comes off battery I can actually get it to the start screen and even set it up, but when it loses battery/ shuts off its bootloop again. I even removed battery and plugged it in with charger and it still bootlooped. I dont understand the problem AHHHH

Could be just a bad battery. Try getting that replaced and see how that goes.

iPhone will just flash apple logo on and off with battery disconnected so it needs a working battery for the iPhone to turn on.

really? How come the phone works when I do my little trick thingy until it gets powered on again. During this time the battery works just fine.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

all though after the update it was working fine until it randomly shut off

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

If the phone works fine when the battery is charged but does not when it drops to a certain percentage that points to a bad battery.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

The phone works with all percentages battery doesn’t seem to be a problem

but it works fine when I get it to homescreen zzz

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Ah ok. Did you change the screen?

-- test audio also. Can you put the phone on speaker during phone call?

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

No I can’t put the phone on speaker during a call

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

If the speaker phone is greyed out during calls and voice memos record shows no recording device found then the phone has an audio IC problem.

To get that fixed the phone will have to be taken to a reputable phone repair shop that does micro-soldering.

this is what is causing the bootloop?

If you haven’t already fixed this, I have found that disconnecting the front proximity sensor altogether works, however, you lose the selfie camera feature…..
