-Since you cant do much more damage to your phone, you might try reflowing your logic board the caveman way. I have saved many graphics cards, a printer controller board, stacks of intermittent wifi routers and a network controller hub this way. Mihno raised a valid concern regarding epoxy backfilled flip chip having blowout from the expanding gases under the chip. I did restore a bad ABS brake module with one of these types of chip though. I was lucky.

-You probably cracked solder connections between the PCB and components. Hopefully not a chip of passive component itself.
+You probably cracked solder connections between the PCB and components. Hopefully not a chip or passive component itself has fractured.
This is a long shot and if it does work, it is not to be considered permanent in any way. My laptop 2 years later is still working great however. Preheat your oven to 400F. Place the logic board carefully on standoffs of some sort on top of aluminum foil lined pan. Paperclips bent into little stands with hooks to suspend the board horizontally by its mounting holes works excellent. You don't want any components on the bottom to contact the foil.
-Bake for 5 minutes. Remove the pan/logic board CAREFULLY from the oven and allow to cool. If it drops or is jarred, you may knock components off as the solder may be wet. With some luck, it may work for you. If not, try again for 8-9 minutes. This is only a last resort vs throwing the board out.
