The Touch ID works perfectly, however, the home button does not click at all. The phone also still vibrates.

Do I need to replace the Taptic Engine? Or what do I need to replace?

Thanks in advance.

Was being the operative word here, right up until she took it skateboarding - with a predicable outcome.

After removing the crushed screen protector and finding there wasn't actually any further damage to the screen other than the original crack in the corner, I proceeded to dig in to evaluate the issue. She brought it to me because every time she turns it on, it displays the Apple logo for a minute or so then goes black only to repeat the scenario ad infinitum.

So I opened up the phone and tried every combination and permutation of plugging and unplugging all of the connectors on the motherboard to no effect; nothing I tried made any difference.

Finally I plugged it into a computer and managed to get it into DFU mode. It told me the phone couldn't be updated and had to be restored, so I said fine, go ahead and restore it.

No luck there; it quit with error 4013. I did have a replacement screen that I was holding onto for the inevitable time when the screen took more damage and truly needed replacement, so I went ahead and plugged the replacement screen in and tried the update again with the same results.

Now it no longer boot loops, but comes up in DFU mode every time.

I'm forced to conclude there's probably damage to the logic board and would like some help in determining what my next step should be. I have a certain amount of equipment such as a multimeter, soldering iron, heat gun, etc., at home but I can always go into work and use the professional grade equipment there like microscopes and hot air stations if need be.

At this point I'm considering the possibility of attempting to reflow the audio IC as demonstrated in this guide that actually describes the situation pretty well.

However, are there diagnostic steps that I should try first? Things like diode checks? If so, what should I check, and what would I be looking for?

I've worked with circuit boards for about 40 years now and the delicate nature of iPhone logic boards will be a first for me, but I have no problem diving in and giving it my best shot.

I'm tagging @flannelist as the closest to an expert in this area that I'm aware of, but would welcome anyone else who has expertise in this area that's willing to help out.

Update 5/6/2023

Tried connecting with 3uTools. When flashing it gets to 19% after the "Sending KernelCache" part, changes to "Restoring", then fails with "ERROR: Device failed to enter restore mode."

Interestingly, when I click on the "Exit Recovery Mode" button on the Device page, it actually does exit DFU and goes back to its reboot cycle. Afterwards I put it back in DFU mode and it stays there.

I have seen other people experiencing this issue as well on this forum, would definitely like to know what's going on. This looks like software related... is this because of 3rd party screens?

Thank you

My phone (iPhone7) got water damaged.

Everything working wells except the vibration, I guess is the Taptic Engine thing.

Im find a weird situation where, under the settings (Sound & Haptics) if I turn on "Vibrate on Ring" and select the ringtones, all the ringtones having the same Ringtones Sound which is (Opening (default) ) sound.

If I turn of the "Vibration on Ring", I'm able to play ringtones when I choose other selection example (Apex, Beacon and etc..)

My question is if I replace Taptic Engine does it resolved my issue?

Thank you.

searching the internet, i found some suggestions about settings in the Accessibility section, but none of those made any difference.

i read in a few places that (and this is conjecture from multiple sources) this is a new "feature" in IOS 15.6 (and later), that when IOS detects there "is a problem" with the home button (meaning it doesn't see the one that was shipped from the factory) it very helpfully turns on the Assistive Touch on-screen button - whether you want it or not. and even if you turn it off, it IOS doesn't care and will turn it back on.

does anyone have any additional light to shed on this?

i get that Apple is just trying to make the user experience better - we're from the government, we're hear to help you... - but when we switch the setting off, it should stay off. "No" means "No" Apple!!!

thanks for any insight you might have.

Since my iPhone's home button assembly (with its separate ribbon cable) is still completely intact, will it keep its touch id capabilities after I replace the extending ribbon cable?

Thanks!

Issues: When i go into voice memo, I can't hit record button. It's grayed out. I try to facetime with someone and it immediately cancels. Place a call and the precipitant can't hear me. Try to record video and there is no audio. Clearly something is wrong with the recording features. Also, if I go into settings--> accessibility and try to turn on or off "Noise Canceling" that selection, where it SHOULD be, is not even in the menu. Just shows Mono Audio and then that's the last option. Strange.

I did a FULL reset, including settings, of the phone and restored from icloud. Updated to most current OS, etc.....and still same issue. So I'm starting to think this isn't software related. Is there anything else I need to check? Oh, I also checked under privacy to see if microphone was in there. Nope. Nothing at the moment.

I'm open to suggestions. I'm comfortable replacing the microphone hardware; however, I want to determine if that is what is bad first, before I spend the money and time.
