Water Damage and Phone Acting Weird?

Hi, So I am getting this weird error where the Watt voltage works but then goes to 0 as seen in video below. I believe this device got water damage but also tried replacing the charger port and battery and still nothing. Screen is black and iTunes doesn’t detect it.

I really don’t want to have to do motherboard repair on this device but do you think that this needs motherboard repair if so where should I look for on iPhone 8 to replace on motherboard?

Thank you in advance and hope someone knows whats going on and how to fix.

Answer this question I have this problem too

Is this a good question?

If you need to ask about water damage, don’t do water damage repair. This is in no sense a DIY repair.

Replacing the logic board will result in a dead home button and very likely dead ambient light sensor.

This was a terrible answer, this is called ifixit no one should say not to do water damage repair or else no one will start doing water damage repair. Instead, someone should explain how water damage repair is performed.

Does anyone have a better answer than this... any answer would be better than saying dont repair it.

Oh yeah I'll show you how people started water damage repairs. By first ruining a couple of devices.

Lessons have to be learned, on dead practice devices or easy repairs. Water damage is NEVER easy. Don't start with a flagship device that may have more than just water in the case.

Do you have any tutorials that you could reference to better understand how to do water damage repairs?

There is no "water damage" repair tutorial. There are some cleaning and refurbishing guides, but "water damage repair" is too generic. What you are really asking is identifying the failure mode and component, then board component level rework and cleaning up corroded PCBs. Some of these are skills to practice, some will need technical documentation, measuring the failed board and analyze the findings on a case-by-case basis.

There are some guides that diagnoses the booting steps by looking how much current the board draws before tripping off, but most of them are in Chinese.

Hi Cameron. Tom has a point in that every device is different and a large percentage of water damaged devices require extensive logic-board level troubleshooting, which is beyond a “DIY” repair. A good analogy would be changing the oil or doing a brake job on your car (perfect DIY repairs) and rebuilding a transmission.

That said, Apple will not do anything for you so there’s no real harm done in opening the phone and determining for yourself if this is something you can resolve or seek out professional help. This is what I generally recommend to folks that want to attempt to repair a water damaged device:

With water damage, you have to decontaminate the logic board before doing anything else, otherwise there will be latent issues down the road.

Not every water-damaged phone is recoverable and depending on the kind of liquid (salty, dirty, filthy), sometimes the success rate is quite low.

The water is inside the phone, on the logic board and under the shields, even under the IC's. The real problem is the mineral deposits that can cause short circuits or the corrosion that is taking place as the water evaporates. Leaving the power on the device accelerates the process. The longer you let a phone sit, the more time you are giving corrosion to damage your logic board. The saltier or harder the water is, the more damage will occur.

  • Open your phone and remove the logic board (follow this guide)
  • Inspect the logic board, especially around the connectors and look for corrosion.
  • Inspect both sides of the board. Unfortunately, most of the board is covered in shields. That's usually where the damage is occurring. The back shields are cloth/paper so you can gently peel those off to have a closer look.
  • Put your board in a container with >90% isopropyl alcohol and let it sit for a while.
  • Use a soft brush, like a toothbrush and lightly brush away any corrosion you see.
  • Rinse in alcohol and repeat.
  • Let it air dry for a day.
  • Re-assemble and hope for the best.

You should also replace the battery if it has swollen. Resist the temptation to pop it to let the gas out. A compromised Li-ion battery is a fire hazard. If the device appears to power up but behaves erratically, then use a tool like 3uTools to flash the firmware as it may be corrupted.

A professional repair shop that does water damage repair may be able to recover your phone or the data because they have access to pro-level ultrasonic baths and specialized cleaners as well as the skills to troubleshoot your board. Many shops have a no fix/no fee policy so you don't have to spend money to find out if the phone is fixable or not.

It sounds like you have corrosion on your components. If it was water damaged the corrosion will begin to form inside, but eventually it will break your phone.

You need to go to a rep center who has the right technology to save your device. Otherwise you will never get the corrosion on the components out. I know that my local rep center works with this company, Techsave who has a technology that saves phones and the data on it. Might be a something worth checking out.
