This is usually caused by a faulty battery or dock connector. “No successful check-ins from thermalmonitord” would most likely be a faulty charging dock assembly.

Voice memo and Siri use different mics. You defiantly have the dreaded iPhone 7 audio IC problem.

The only temp sensors I have come across on the iPhone 8 have been located in the parts of the phone like battery, cameras and the dock connector. There might be one in the Wi-Fi chip but I cannot confirm. When it comes to temp sensor problems the most common cause is a faulty dock connector. You will need to replace this first.

If it has no face ID or true tone it would confirm it has had a replacement screen installed. People planning to sell their phone will opt for the cheapest screen to replace there broken one. With the iPhone X there are three screens you can choose from, an LCD, hard OLED and soft OLED. The LCD screen is the cheapest and are not really designed for the iPhone X. I have not herd of a temporary fix for this problem. Without seeing any images of your screen I would make sure it is not a swelling battery that is causing the problem, 85% battery health can cause this. I usually recommend a battery replacement at 87%. I would order a new screen and battery for this phone. There is not much else you can do.

If it still chargers wirelessly it will be okay and will not cause any future issues.

You will need to remove the Wi-Fi chip and check all pads. One or more of the pads are probably loose and the trace damaged. You will need to run jumpers.

No backlight and boot looping will be separate problems. For your backlight problem assuming it was working before the repair I would first rule out the screen and make sure none of the pins in the logic board connector have been pushed into the plastic. As the backlight components are on the other side of the board I doubt they have become faulty unless you connected the screen while the battery was connected. There are three pins for the backlight on the connector. You can also check them with a multimeter to check for a short or open line. The boot looping will probably be caused by the battery or the connector, again make sure the pins on the battery connector are not pushed into the plastic. You can also put some pressure on the connector and see if it boots. You will also need to rule out a faulty battery.

If your phone detects it is connected to the charger it could be a board issue. There are two mosfets near the battery connector. If any one of these have been nudged it will produce the problem you are facing. You will need to check around the battery connector with some magnification as these components are very small. Make sure none are missing or have become loose.

I am not sure that it being jailbroken would cause this. The main reason this usually happens on an iPhone 6 is a faulty home button flex. I would replace this first and see if it fixes the problem.

Just follow this repair guide.
