@alexandralulu PRSO is the barometer and it is located on the Charge Port Assembly. The issues with that are most likely Charge Port Assembly or its connector on the Logic Board. Getting used parts is always a crap shot. I would run the panic log once more and then post it on here with your Question. Use this guide [guide|21499] for that. Let's see what it tells you. You may just have to replace the charge port once more :-) but we will know more once you post your log. Read through this wiki [[iPhone Kernel Panics]] on how to get to the log etc.
