Error 4013. Broken Connector on Motherboard The Problem?

Got this iphone 5s here that i cant restore no matter what I try.

I have disconnected every flex except battery and usb port, tried different battery different usb port.

It always throws error 4013. (Loads to the apple screen where it shows progress bar of the restore, but instead of showing the progress bar it reboots itself)

In my research i see it could be a bad front camera flex, but unplugging it doesnt help.

When i kick it out of restore mode with reiboot it bootloops, sometimes stickin on the apple indefinitely or sometimes it will flash a red screen for a split second and reboot.

So i checked for damage on the board. The only damage i can find is the front camera connector.

On one side, the pins inside the connector are broken. See pic

Could this problem be caused by a broken camera connector (even when the camera is not connected) or could it be something more sinister?

The screen that came with this phone is not original, and the screws could have been placed wrong. They were right when i removed them but who knows what was done before that.

Or the nand could be corrupt?

I have a donor board to replace the connector but dont want to risk it and waste parts if its likely something else.

Thanks in advance for any help!

Answer this question I have this problem too

Is this a good question?

That board looks water damaged, clean it with isopropyl alcohol and then try to restore.

Its not water damaged from what i can tell. The water damage indicators are white and intact. Theres no residue, corrosion, nor burnt capacitors/resistors.

Just looks that way in the pic (dunno why) but in person its sparkly clean.

The connector having several pins severed is the only fault i can find visually.


Take the connector off and see if it restores, if it does not it might be a NAND problem.

3. Is wifi network working properly?

4. Clean up youriPhone.

5. Restart your computer, reset your iPhone.

If these fails, you should contact Apple. Hope it will work out.
