You don’t have to split the board but be aware the CPU is underneath and the NAND will require more heat for its removal. If you have an iBox Mini you could test the NAND and reformat if necessary without removing it. I use it on the X after a bottom board swap to unbind the Wi-Fi from the NAND.

The iPhone 7,s develop a signature fault with the audio. However from experience there is a good chance you just need to replace your charge dock assembly as if it was the signature fault you would have no Siri and voice mails would be greyed out. The charge dock assembly is not expensive and there are guides on this site to help you step by step in the replacement.

Are you copying the screen data to the new screen? If so I have seen this happen a few times where the burn gets transferred as well as the data. I don’t think there is much you can do except delete the data off the screen and lose true tone.

These shields are not the easiest to remove as they hold a fair bit of ground plain. I use full heat and air flow with a large or no nozzle. The shield you are talking about should come off when the hot air temp reaches around 400 degrees. All hot air stations are different; the temperature displayed may not be accurate due to the age of the machine or its make. You are right thinking that exposed heat might damage the motherboard. The other method you can use is to cut it off. I see a few that come in with prior repair attempts which have had the shield removed this way.

In rare cases sometimes you need to reset all settings on the phone after replacing the camera. This is in settings > general> reset> reset all settings. If that doesn’t work backup up your phone and do a restore. If that fails it will be the camera that is faulty.

There is no reason you need an OEM reader. You can pick up duel sim readers for the iPhone 12 at aliexpress and other stores.

You will need to rule out the charge port. If it still doesn’t charge it will be one of the charging IC’s Tristar or Tigris that will need to be replaced.

You will need to rule out the screen as the home button flex may be damaged. But from what you are describing could be a faulty turtle IC which is on the home button assembly and one of its jobs is to detect pressure on the home button. If you have nudged the turtle IC while transferring the home button this could be the cause and would be a costly repair with no guarantees.

I would try replacing the home button flex cable as it might be damaged. You can purchase the flex and back plate for around $5.00 or just the flex for less.

Your computer will not recognise the phone until you enter the passcode. This is a security feature apple brought in a couple of years ago. You will need to put the phone into DFU or recovery mode and restore it.
