Hello! 2-3 weeks back my FP3 had an accident and got submerged in shallow water for ~1 hour. To make matters worse the phone was probably on when taking the dive. I was not around and a friend of mine (hero) took the phone out of the water and put it in rice overnight (I only later found out rice is a no go, dont do this)
It was the next morning when I found out and started to take the phone apart. I put all components to dry and submerged them in 96% isopropyl alcohol overnight. I also ordered a new battery because I read the old one was most likely dead. I like the FP idea of being able to replace individual parts/modules, so I searched the #waterwiki for ways to salvage this phone. However I have not found a post with my exact issue, so I am here to ask for advice.
State of phone
Definitely water damaged phone, submerged in IPA for +8 hours and thoroughly dried (1+ week) and cleaned.
Reassembled with a new battery and charged fully (green LED shows)
When charging LED indicators seem fine, however, when trying to turn on the device screen stays black. After holding and releasing the power button for a while the LED indicator flashes blue.
What can I try to salvage this phone? Are there individual modules I could replace or is this probably beyond repair and should I cut my losses?
Thanks for your help!
