Using a “Short Killer” is not a silver bullet. If you don’t know what your doing, you can cause more damage to the board then classical short hunting. All the short killer does is pass a very high current, hopefully set at a low voltage so that it doesn’t damage IC’s by activating them, to essentially fully burn through the shorted component. IMHO, this is the tool of last chance because you can easily destroy a board if you are using it blindly and without fully understanding what it does.
I’m saying this in a general sense, not to you in particular, because the risk of this new tool is a bunch of dead boards.

We will need the history of the phone plus a little more info. You say that you used short killer to remove the short on VDD main but then saying there is still a short on VDD main.
• What is DCPS before prompt to boot?
• What voltage did you have short killer set to?
• What component did you remove to relieve the short?
