iPad Mini wont boot past Apple logo
 

So this ipad came in having been bent pretty severly by the customer, not enough to crack the glass though. the device will power up but will only boot to the apple logo and then shut off. what components on the board should I be looking at to replace or reflow?

Try to rebot system in DFU mode. Hope it will be help.

its the battery or battery connection. replace them and it will boot up perfectly.
