1 iPhone 6S can't restore error 6 or error 9
Yesterday one of my customers came to me with an iPhone 6s that changed the LCD by himself. After replacement the battery started drain faster than usual, I told him that it is not battery problem but LCD problem and need to be replaced again. He didn't want to pay for other LCD and he insisted to change the battery. This didn't solve the problem and after 7 days of use phone stack on apple logo and started boot loop. then he left the phone charging all night but it didn't help, his last action was to restore the phone but it failed. Now I have the phone and every time I try to restore I see sometimes "error 6" and sometimes "error 9". Does this phone has motherboard issue? Has someone come up against same situation? I would appreciate if someone could help me, thank you!!!
Update (11/25/2016)
i checked the motherboard by myself with a microscope, i am not so experienced but nothing unusuall and no missing parts near the FPC connectors, but when i push the power button and phone start and try to boot this part of the motherboard get really hot
There is the Memory Chip in this part of the motherboard and i think that this phone is shorted in there. Can someone tell me if this phone can work again or not?

Thanks for your time. In iPhone 6s what screw hole is most sensitive and can cause this problem. I have a microscope and i will inspect the board near the LCD, battery, camera, digitizer connectors and i will replay here. Thank you again for your help

Exactly the same situation and the 3u tool below it self is giving us 6 where as the itunes is giving me 9 - between the 69 and the customer DIY'n I'm clueless as to what do do next.
1) ChargerPort verified by disconnecting/reconnecting battery & plugging in. 2) Phone charges to 'Connect to Itunes,' mode
Don't know why but I have the jailbreak blues, asin, I think this phone was previously jailbroken and in 3u/itunes exactly at firmware part it crashes and loops back to 'Connect to Itunes,' error

That shield covers the CPU. It is normally warm but not hot when the phone is idle. The memory chip is on the underside of the logic board where the SIM card reader is.

in this model CPU and memory are in the same Chip. This part was not warm but really hot, now I tried to restore from DFU and I can only see the connect to iTunes image on my phones screen
