so, i plugged my iphone to a wall charger and let charge overnight, but in the morning i tried to turn on the device and it shows apple logo then a blue screen, i tried to connect it to my computer by dfu mode but it says usb device not recognized, so i opened the device and unplugged the battery connector and the blue screen disappeared, it started to loop the apple logo without the blue screen
Hello did you have recently change the iphone screen ? It looks like a screw damage due to the exchange of screw length during reassembly. If it is this, then you may have damaged the mother board. In the past some microsoldering shop could repair this but i don’t think it worths the cost now.
