Nand flash error/ error recovering

Hi

Been given an iPhone 5c which someone has attempted to replace the screen themselves, by the looks of it, they have bought a whole unit with the flex assembly built on, as the copper tape looks untouched/brand new.

Anyway, 2 faults are lines going down the middle of the screen. And comes up with different errors when trying to recover (it's stuck on the "plug into itunes")

The lines was simple, looks like a faulty screen, as I put a my own on there and it displays without the line.

The second though, I can not get past the different itunes errors which point to the usual, try a different cable etc.

When it boots, apple logo shows up, and then you get the nand flash error 601, then it comes up with the error on iTunes.

I've disconnected the front camera, as that usually gets damaged, and I've unclipped every flex cable apart from the charging port so it can still talk to the pc.

Tried the host files, different cables, different usb slots, but the same every time.

So I've taken the rubber off where you would attempted lcd, and directly under where the face time camera will snap in, it looks like a resistor of some sort is missing? Could this be the problem?

The picture isn't brilliant, but it's where the bottom right screw hole is, 4th resistor from three right, just under where the camera plugs in.
