iPhone 5 stuck on apple logo then shuts down
I have an iPhone 5 which is water damaged so not expecting much! Anyway, when I turn it on, the apple logo stays on the screen for about 30 seconds then the phone shuts down. I am unable to enter Recovery or DFU mode so cannot restore. I’ve noticed it has a replacement battery which could be the culprit but powering it form a power supply gives the same result. I would like to get the data off it for my friend so any suggestions?
