Booting and Restoring issue (RSOD)

Let's not make this a wall of text, it's quite simple.

I received a iPhone 5s. It would not boot.

Water Damaged

I began curing the iPhone in a ultrasonic cleaner with 91% isopropyl achohole, wiping corrosion with a gentle brush.

It booted! But as time progresses I realized that it booted to a redscreen, fading to black.

Figuring it was a software or firmware issue, I booted it to DFU. Whilst attempting to restore I get the error 4013. Simultaneously seeing the Redscreen on the iPhone.


It's a bummer. I have microsoldering and heating gun's at my disposal. Along with replacement chips.

  • I had the camera flex detached.
  • Restore attempted. (Error 4013)

I have the exact same problem, except the phone is not water damaged. I've tried everything I could think of. Disconnecting the sensor flex, camera & digi & restore, new battery (this happened to the phone a few weeks after I had replaced the battery in it), new LCD & restore, new charge flex & restore, tried DR. Fone iOS system recovery... Nothing is working. Still keep getting error 4013. Anyone have any ideas as to what is causing this?


Also, I have noticed that the phone sometimes produces a high frequency squealing sound when it is plugged in.

Any hot spots on the phone? Very likely a short caused by a blown component. Can you remove the shields? Inspect the components under as close magnification you can get. Look for blacked or cracked components. Look near any Hotspots on the phone. Remove the component and attempt to replace if possible.

Okay, any micro soldering items on the cheap I can get?


Have you tried another charging port dock assembly? The one in there may be damaged from liquid / corrosion.


Yes I had tried
