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.

Ifixit sells the battery. It comes with the tools you will need. MacBook Pro 13" Retina (Early 2015) Battery

It is normal for the phone to boot when inserting the lightning cable. Your problems are most likely the screen and home button connectors. Remove the screen connectors and reseat them be extra careful with the home button connector and flex.

This is not possible. The data on the NAND is encrypted which is serialized with the CPU and logic eeprom. Even if you put your NAND in another iPhone 8 it would not work. There might be a really slim chance if you use a program called 3uTools and select restore while retaining user’s data. It should bring up the password screen again where you could have one more chance at entering the correct password but most of the time it fails.

It is the shield for the home button connector. You can see it on step 9 of the ifixit guide.

Yes you will get this warning on the SE 2020 model.

It is hard to diagnose this problem over the internet. If this came across my desk here is what I would do. I know you have completed some of these steps. ·         Remove the logic board and install it in a known good housing including a known good screen and battery. (If it boots you know it’s a parts issue) ·         Take a diode measurement of the PP_VCC_MAIN line. (A partial short on the 6s plus can cause your issue) ·         Try an update. ·         Put some pressure on the CPU while booting. ·         Check the PP1V8 has correct voltage. ·         Replace the Tristar IC. ·         Check the logic eeprom. ·         Check Baseband PMU and CPU on the 6s plus if they are faulty it will produce your problem. If the update you performed was successful with no errors I would be inclined to say that the NAND and CPU are okay but you would need to check the power rails on these in case there is a partial short.

The batteries have different capacities but you can still use them as the 6plus 6s and 6s plus all use the same connector.

If the connectors are properly seated on the new screen and you have tried the old screen again and touch works fine it will defiantly be a faulty screen. Return it for another one.
