Your case have problem....check if the PCB is ok.....try to reflow UEM and CPU.

Did you try to power on the phone on wires while in chasis?Yes-you need a resistor between tne GND pin and the BSI,I think that a 10K will do the job.If the phone turns on-probably the battery pins are the problem,especially teh middle one.Try to stick them out but not to beak them.If it not turns on-try re-heating or reballing the UEM and/or the CPU.
Sincerly I think that you don`t have to heat anything...
Good luck
