Hello. I am trying to restore the firmware on my iPhone XR. I start up the iphone it goes straight into restore mode. I try restoring the firmware from restore and dfu mode. It says preparing iphone for restore. After it says iphone is restarting it restarts and goes straight into recovery mode again. I’m thinking it is a hardware issue. I may be wrong. If it is a hardware problem what part do i need to repair. The front and back screen is cracked. I don’t know if that affects the restore process. If anyone can help me that would be great.

Did it get wet? If the back or screen is cracked liquid can come in. I would open it up and check if it has liquid damage and go from there. Update (05/14/2020) It sounds like you need to send it to a repair shop. I would recommend jessa at ipad rehab ipadrehab.com or Jason at sts telecom ststelecom.com you should check out there YouTube channels. But they can figure it out. Hope I

Try to disconnect the front cam flex cable, rear cam flex cable and lcd flex cable you only connect battery and dock connector flex to mother bord and then connect the iphone with itunes. If it boots up you can conect flex cable one by one to check which part give the error when connected to motherbord.
