I think the charger port flex are identical but I need to make sure before I try to solder one on.

No, they are not compatible with each other.

The part where you put the disk in and the blu-ray drive feeds in the disc that is usually a probably with the two light blue-ish rollers that roll the disc in. Rollers do wear out over time and can also get dirty. What I usually do is rub clean it lightly with isopropyl alcohol then sand the rollers about 2-3 runs on each rough surface sections of the rollers. For the triple beeping / self-ejection by itself check for dust near the metal silver piece on the bottom cover. Clean dust if there is some dust there as that interferes with the ejection button.

There are lots of different models of the A1502. From 2011 to 2015 and the parts are not compatible vice versa. It needs to be the same year including the late 2013 as well. Not compatible with that one. The unibody models are the one that come with optical drives. The retina models which yours is with batteries held in with adhesive, SSD and no optical drives.

The only way to get battery health to show up on replacement batteries would be to transplant the gas gauge board from the original battery to the replacement battery via soldering. Not really doable without experience in micro-soldering. The batteries are serialized and only the battery that was shipped with the phone or replaced by apple will show battery health unless gas gauge is retained as said above. The gas gauge board is a little daughter board that is located at the bottom of the battery covered by a black sticker. Personally I would leave it as it is and not risk damaging the battery. It shouldn’t cause any problems with the phone other than no battery health reading.

Someone put a long screw in the short hole which cuts through the paint finish and luckily did not crack the screen as a result of doing so. The home button bracket that covers the back of the home button assembly has 4 tri-wing screws that hold it in.

Yes, a common cause is one or more lose solder balls that cause a break in a connection between the baseband chip and the logic board. What happens as a result is missing IMEI / Modem Firmware (Also when dialing *#06#). It will cost more than buying a second hand iPhone 6 which makes it economically viable for repair as it requires a micro-soldering technician to do the repair. I would guess at least $80-120 USD.

Is an original charger being used or is it an aftermarket one? Also try cleaning the charging port because there is probably some lint / metal foreign pieces stuck to the magnetic part of the MagSafe charger.

The service message sometimes is caused because of a bad connection of the middle pin on the battery connector coming from the battery. It can be fixed sometimes by applying more pressure onto the connector or cleaning the connector. Worst case you may need to replace with another battery that fits better onto that connector or get the battery connector on the logic board replaced. Some replacement batteries may have the same battery serial numbers for simplicity sake when mass producing replacement batteries.

Yes they are compatible. To confirm either of those you’ll need to boot a MacOS installation media (via USB or internet recovery) and check if it is detected under disk utility.

Without bracket is fine, the connectors tend to only maybe disconnect when the phone is dropped.

If you have isopropyl alcohol on hand. You can use it to help weaken the adhesive temporarily when lifting up the adhered home button.

Yep, clean the old adhesive and apply some Tesa 4695 or 61395.

I honestly do not understand why the back cover is removed from the mid frame, you can remove the mid frame silver plastic with the back cover anyway.

They can’t be both PMI8994 Power Management IC’s I’ve looked at them under an microscope and one is PMI8994 and the other is PM8994.

Unfortunately the connector plugs are different and the cables go in different areas.

No. Different connectors.

I would call that a grounding plate as it looks like it provides grounding for the power button assembly to the board. Without ground the power button would not be able to send current pulses when you short the power button by pushing it from the power button itself > power button cable to logic board.

Not sure why they did this because they could of just provided ground on the cable itself. That's my understanding because that put should not of been designed like that.

The thickness / coverage of the area available to put the adhesive is plentiful which allows you to use more adhesive than you need. Anyway what I use is red double sided tape as it's adhesive strength is very good and the thickness is good to use in this case. It's called 'PET red double sided transparent tape'.

I think iFixit sells rolls of them which aren't really expensive at all.

Yeah don't listen to this comment. I replace Macbook Pro glass regularly and this is one of the worst ways to do it. I never replace glass without taking the screen assembly from the MacBook first.

The reason why I always separate the screen assembly from the MacBook is because it's just going to increase the difficulty of taking off the glass so much to the point that you regret that you wasted your time trying this and you could of done it in less time if you took the screen off from the MacBook.
