Rear Camera Data Line Fail.

Hey guys. Ran through the U204 Reflow process on a hundred i337s to get the sim working. Fixed most of them fine, however, three of them have a failure on the camera.

Running The camera through the App, the screen is just black, and says, "Updating firmware, please wait" and never runs.

Running through the Testing Screen from the Dial Pad, the front camera works fine, however, the Rear camera, (Megacam) gets the error "Data Line Fail"

I'm sure i blew out a component on them, i was just hoping someone out there has had more experience with this failure, and has found the way to fix it.

If you could send me the IC model, and a picture with the location highlighted, i have plenty of damaged boards to take the part off of.

Thanks so much in advance.

Answer this question I have this problem too

Is this a good question?

Did you already check if components were missing?


scanned board under 10X Microscope. No missing components.


What about the connector?


brand new. tried replacing. same failure.


Get a multimeter and check all the traces, make sure they are going from the connector to where they are supposed to go.
