Hi,

I figured I would share this one with the community.

I have an iPhone 7 I have spent 3 hours on.

I have replaced Tristar and Tigris and the draw stays the same.

I have checked for VBATT and VCC_MAIN both are present.

I can't find any unusual diode mode measurements on any of the connectors, the only part that seems to get remotely warm is Tigris but I have checked all resistance measurements under it and they are all normal.

I have given in, the phone doesn't boot, no dfu, it just stays at 0.42a draw the instant you plug in the USB.

The only thing that is worth mentioning is the case shows signs of being bent by a few degrees at the sim tray area, I put it down to a potential NAND issue where the bend could have caused the pads to pop.

I haven't tried removing NAND as it often causes me lots of headaches, any other suggestions besides removing NAND would be appreciated (recall and is an absolute last resort in my eyes)

Thanks
