I have herd of this happening on the 11 pro but have not experienced it myself. The easiest way would be to use something like the iBox 2 and retrieve the number from the sys config. I would presume it would be listed.

When the iPhone 6s or 6s plus starts overheating and the heat is coming from the top of the board it usually means the Wi-Fi chip is has a short inside it. The Wi-Fi might still work for now but it will not be long before the phone will be inoperative due to overheating. The Wi-Fi chip is located on the underside of the board under the display connectors. I would suggest an upgrade as the repair would be more expensive than the phone is worth as replacing the chip is not straight forward and you also need to unbind the Mac Address from the NAND for the new chip to work.

You need to rule out parts first. On the 6 plus the main part to replace would be the battery. If it still will not boot you would restore the software with iTunes. If it still will not boot with new battery and a restore it will be a board issue which will mean you will need experience plus ·         Microscope or some sort of magnification. ·         Multimeter. ·         DC power supply. ·         Hot air and soldering station. ·         Board view software. ·         Tweezers and other microsoldering utensils.

You cannot remove this chip without a hot air station. If the Wi-Fi IC is shorted which does occur on the 6s you can scrape the top layer and find the short. I usually try this method before removing the IC. Remember if you replace this chip you will need to un-bind the Mac Address from the NAND or you will have no Wi-Fi.

It is only an adhesive so the flex assembly sticks to the housing. Double sided tape will be fine.

If you are sure classic and smart invert are turned off it will most likely be a software problem. I would back up the phone and restore with iTunes. It will not be a virus.

I would think that the repair shop you sent it to would have ruled out a faulty screen but this is the first thing you need to rule out. The iPhone XS is a doubled layer board with an interposer board between which consists of pads that allow the voltage and data signals to go from the top board to the bottom board. A common issue on all the X models is that if the phone has ever been dropped it can crack the solder pads to the interposer board and they can become oxidised. Since the touch connector is located on the bottom board it is likely the problem. If this is the problem a good repair shop would split the boards and reball the pads and maybe run a jumper if the pad has come off completely. A dodgy repair shop will just reflow the board with hot air or a heating platform which will only be a temporary fix.

This error log is telling you that one of the sensors on the charge port assembly is faulty. It is trying to communicate with mic1 which it does every 3 minutes. If it doesn’t get a response it will restart the device. A new charge port should fix the problem. You will need to purchase this part from a reputable store and you can follow this guide.

Jerry is right there are a number of things that can cause a boot loop on the 7 series. The most common cause is a faulty battery or a faulty front camera flex assembly. I would open up the phone and disconnect the front camera connector from the logic board. If it boots normal you will need to replace it. If it is still the same you will need to install a replacement battery.

You will need to replace the front camera flex assembly not the speaker. This will fix your issue.
