iPhone 6 has no power, not charging nor detected by iTunes
iPhone 6 logic board is dead. No water damage. Previous owner said that it showed error 4005 when restored however iPhone does not power on nor detect on iTunes. I have disconnected everything except battery (known good). Followed this video [https://www.youtube.com/watch?v=GHw1WX-CC_Y] and everything looks good so i'm ''guessing'' that the power management unit is fine. No shorts on '''vcc_main'''. What should I check for please? '''Note: Phone may have been dropped once as there is a really small bend in the frame.'''
