Case Study Summary
- Device: Samsung Galaxy S20
- Problem: Dropped in the ocean (salt water damage) and would not turn on
- Complication: Two prior repair attempts before the device reached our lab
- Recovery approach: Logic board inspection followed by a logic board chip transplant
- Outcome: All data recovered
Galaxy S20 salt water case study shows what mobile phone data recovery can involve when a Samsung Galaxy S20 is damaged by ocean salt water and will not power on. The client first visited a phone repair shop and then another data recovery company, but neither could help. After examining the logic board, we found extensive salt water damage plus signs of previous repair attempts.
Galaxy S20 salt water case study: what salt water damage can do
Salt water can cause corrosion and conductive residue across components and connectors, which can prevent a phone from powering on and can complicate component-level work after earlier attempts. For a general explanation of corrosion on metals and electronics, see Corrosion.
What we found during assessment
- Salt water damage on the logic board: Extensive damage consistent with ocean exposure.
- Previous repair attempts: Prior work made the job more complex and reduced the margin for error.
The recovery process
Based on the condition of the board, we decided a logic board chip transplant had the best chance of success for this job. The process shown in the video was:
- Logic board inspection: Examine the board to locate the fault and assess damage.
- Chip identification: Identify the chips that contain the essential data.
- Chip transplant: Move the required chips to a replacement board using precision microsoldering techniques.
- Test for data access: Power and test the repaired assembly so the data can be accessed and extracted.
Result
After the chip transplant, the phone powered on and we recovered all the data. This Galaxy S20 salt water case study is a good example of why chip-level methods are sometimes required when a device will not turn on after salt water exposure.
Service process for mobile phones and tablets
- Fixed price service

Frequently asked questions
Can you recover data from a Galaxy S20 that will not turn on after salt water damage?
Often, yes. If standard repair has failed and the phone will not power on, chip-level methods such as a logic board chip transplant can sometimes restore access long enough to recover the data.
Do previous repair attempts reduce the chance of success?
They can. In this case, we saw damage from salt water as well as evidence of previous attempts, which can make diagnosis and microsoldering work more complex.
What does a logic board chip transplant mean?
It means transferring the required data-related chips from the damaged board to a working board so the phone can start and the data can be accessed for extraction.
