I have a iPhone 5s that is stuck in boot loop and goes onto a red screen then starts the loop again, how can i fix it? Thanks!
From my experience it’s either a bad front camera cable, Tristar chip (Charging chip that would need to be replaced via micro-soldering / board level repair) or at worst the NAND flash memory chip needing reprogramming and/or replacement. Try unplugging the front camera cable then power it on again and see how that goes. iPhone 5s Front Facing Camera and Sensor Cable Replacement
It is a board level issue like iphone 6 touch desaese
