I replaced the battery in my iPhone 12 and now my phone doesn’t have working cellular. It might occasionally give me a few bars but mostly not, also when I tried to update on wifi it said it couldn’t verify my update because it wasn’t connected to the internet even though wifi was fine.

I suspect I have done damaged or dislodged something since opening the phone was very difficult and my attempted as removing the old gasket were also difficult so I could have caused damage then.

In order for me to at least attempt to fix it I need to know what the most likely component to be faulty is and where it is. I’ve successfully replaced many batteries on older models but i’m a novice when it comes to other parts in these phones so looking for some direction. I have gone back into the phone reconnected everything and gone over it but I can’t tell what might be wrong. Any ideas and pictures showing the potentially offending parts would be helpful.

Recently i just changed the iphone 12 housing

There is black tiny square thing on mag safe magnet

it looks like made of magnet

My new housing doesn't have black thing so i also transfer but it's just sticky onto it

What is this for? I shouldn't transfer to another?

The black thing located in green Question Mark area as below picture

Another question

There is too much static noise while recording video

Is this very normal? Or some wrong with my repair?

Plz let me know thanks guys

Also should I expect any 'ingenuine screen' pop ups?

No zoom & while editing portrait filters not working

I’m not interested in fussing around with transferring components over to a new flex to keep Face ID (because reasons) so he’s just getting a Self Repair display and I’m going to do it for him since his wife wants to make sure Face ID stays intact.

In the mean time. The ALS works sometimes, if it feels like it. I’m figuring there’s some corrosion or something somewhere I can’t see because my microscope is at home. How risky is it to try and clean the ALS up with some isopropyl. Is that going to murder it more?

Noticed the screen was blank (black screen). The battery was about 50% and their was no issues at all prior to the event.

I have tried ways of turn it on but to no avail

What in hell should i do?

Has anyone here successfully updated their TBK-958A to fit the iPhone 12 and up models? We tried different formats on the USBs and that didn’t work. If anyone here has had some success please feel free to help a fellow tech out. :)
