Hi, Got this iPhone 6 that was dropped down the toilet. Taken off the screen as around the pins there is what looks like a bit of mould/corrosion also at the bottom of the phone around the mic and speaker there is white marks which I think are corrosion too. Here are two images https://ibb.co/c10Rdk
Any recommendations?
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. That said, IMHO, it’s always worth a try otherwise we are just piling up the e-waste. Here’s what you need to do: 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, 80% of the board is covered in shields. That’s usually where the damage is occurring.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.
