That is a capacitor on the battery power rail. There are three other capacitors on that rail so at the moment everything should still function. But since you bridged this component and there is a scorch mark I wouldn’t wait too long to replace it. If this component fails in the future it will send all the power to ground. Your device will no longer charge or run on the battery. The capacitor you are after is 1UF 10% 25V X5R 603-1

It’s the front flex cable connector it is for the front mic, strobe driver and proximity sensor. These often fail producing the boot loop you are facing. The only way to rule out a parts issue or board issue is to replace the flex assembly and see if the problem persists. Note that you will lose face ID.

You have ruled out parts so I would suspect a logic board problem. If you have a diode setting on your meter post the values of the components marked in red (with red probe on ground.) Fist one is PP_VCC_MAIN. Second is PP_BATT_VCC. Remember to have the battery removed when testing.

I have not seen one of these programmers. The one you are referring to could be used on iPhones before they introduced the Qualcomm Baseband. As far as I’m aware you cannot write to the Baseband QUALCOMM CPU. In any event the basebands become faulty usually due to an internal short so you wouldn’t be able to read the information on it to start with. On the iPhone 6 the common baseband fault a Brocken trace due to flexation. You can fix this with a jumper wire and a reball. On the 7 series if it is a Qualcomm phone it is usually one of two things, either the baseband PMU has failed sending high voltage to the baseband CPU causing an internal fault or it has had an attempted audio repair using too much heat causing the under filled baseband CPU to fail. This can be fixed by a reball. On the 7 series if it is an Intel it will always be after an audio repair attempt and the baseband can be reballed.

If your phone has a passcode you will need to enter it to obtain USB. So you might have to install a replacement screen. If you haven’t got a passcode the phone will connect to iTunes with just the dock connector and battery but it would have needed to be trusted before on that PC.

It could be a faulty battery but battery drain plus getting really hot usually means there is a short on the logic board. It could be a cap or an IC. If you need the data you will need to send it to a reputable repairer unless you have the equipment and experience in microsoldering.

It will more than likely be a parts problem. ·         Faulty charge port. ·         Faulty battery ·         Faulty top flex. Try booting with it disconnected. If it still will not boot it will be pry damage. You will need to check around the connectors under a microscope and see if any components have been nudged off there pads.

Can Siri hear you? Sometimes the assembly can get damaged while transferring. Check the 4 contacts can make proper contact with the speaker. If you cannot find the problem you will have to purchase another front camera assembly. If this still doesn’t work let us know.

It is most likely the batteries. You would need to rule them out before diagnosing any further.

The new NAND will have to be programmed. You cannot just swap NANDS even from another 6s plus. If you haven’t got a programmer the other way is to purchase one through aliexpress, you would need to give them the syscfg info (serial number, Wi-Fi Address etc.) from the original NAND and they will program it in for you so as you only have to solder it on.
