Here's my deal, it is a case to case basis when we talked about corrosion. As long as the end user of the device does not try to power the phone on and from day one it will be subject for microscopic inspection for corrosion, 80% of chances you can save the phone from further damage. I warn you not to try powering it "on" unless you do the following: 1. Ask the owner how long it was damaged. From my experience less people are being truthful. So, you have to do ocular inspection. When "rust" already present on the board, chances are very thin for recovery/restoration. This means it is in advanced staged of oxidation. 2. Ask the owner what position it was soaked in (angle). If it is only on the sides, top, under or the whole phone. This will give you an idea where to begin. Again, ocular inspection is the best way to do it. 3. After questions above are done., you can begin by taking out the baseband/bga chip "metal cover". This will exposed all visible corrosion (using microscope). 4. Detailed and Record all...

First, Kindle charging port have different pin configuration and it wont be 100% compatible. Second, if you want to replace ipad air charging port, you must to have a hot press equipmwnt to do the right job.

i already fixed mine by reheating the u2/a5 chip. its an hardware issue not software.

Disassemble the phone and look for a possible corrosion and shorts. Most of the flash "always turn on" problem occurs when parts shorts with the other component. Or it you may want to look at your apps (i.e. flashlight,dimmer,bulbon,etc.) it might be in the "turn on" mode operation stucked into it.

The RF cable shield can be taken out. It is only clipped on the sides. If you careful enough to take it out, it will not be deformed or you formed it back in place as you want.

You may not want also to installed it back (i did mine without the shield) Putting a kapton tape or any tape in the ZIF connector will do the job.

It is more risky breaking the ZIF lock if you poke it with a pick while the shield is installed.

But, then again it will be your choice. Goodluck.

It will for sure lose it's water-resistant properties. So, please replace the water-resistant adhesive before assembly.
