This iPhone 5S boots into Recovery mode. When connecting to iTunes and clicking restore, the device turns off right after the extracting software step. Then restarts into DFU.(iTunes err 4013)
Any ideas? Thank you!

Error 4013 is cause by a misbehaving NAND or just flat out faulty NAND. First I would try other tools before you declare this phone bricked. Like try to use 3u tools or something like that. Typically if a device can’t leave DFU mode then the logic board needs to be repaired.

Thank you for the tool. It seems really handy. Indeed, it can see the iPhone, but it can't determine how much storage it has. So i think it is safe to assume the NAND is dead.

You can try to to connect it to itunes and click on restore without the screen attached to the iphone. Afther that you can connect the screen back to your iphone, but don’t forget to disconnect battery first before putting back your screen.

Unfortunately, this did not fix the issue on this specific device. I will keep this tip in mind though for possibly fixing some of my other bricked devices.
