iPhone 5s Dead, Not Charging, Not Turning On, Touch ID stop Working
Question:
Does changing u2 ic or memory chip will make touch id to shop working?
My iphone 5s suddenly turned off. When I insert charger it turns on and show apple logo and then turn off and then this whole process starts again (turning on>show apple logo>turn off) and it continuous as long as charger is inserted.
When take out charger, phone turn off and no matter which button combination you use and how many times you use, it doesn't turn on. If I do DFU mode method, although screen stays off (black) it tries to restore but only to give an error each and every time.
So I went to technician and he said your memory or u2 ic is at fault and need to be changed. But after changing it he now told me that touch id won't work now! But as touch id is linked to processor so is it possible that changing u2 ic or memory chip make touch id stop working? Or it's his fault and he damaged something, bcuz before it touch id was working 100% ok!!
Is this a good question?

His fault. I've had a technician replace many charging ic's on 5s and 6 without issue.
Sudden turn off sounds like maybe the phone has been liquid damaged inside?
I doubt he would of changed memory chip as that is a lot harder to do and requires reprogramming the memory chip to get it to work on the phone.
Just curious, was another battery tried on the phone?

I took phone back, he said if I change memory chip, touch id won't work and yes he said need to do programming but he said after changing memory ic, IMEI will be different. My phone is completely dead now. And yes he used other battery. he said it's not u2 ic, it's memory ic.
connecting it with itunes, i get error 2005 during restore. and my phone stay completely dead.

Well the phone was dead to begin with, sometimes these end up being unfixable unfortunately.
Ah okay now that makes sense. I think your technician is doing the right thing.
Memory IC faulty is the worst, sometimes it can be reballed to fix and worst case scenario needs to be swapped and/or reprogrammed.
Yeah touch ID is linked to the board might not work when memory chip is reprogrammed / changed.

If imei is different and uve restored it are u sure that's even ur phone board, sounds more like they've swapped the board with another one...
