@refectio is there any real way to tell if bb is bad or if its pm8019. this phone was liquid damaged before and dead. i got it working again but i worked around pm8019 and the audio ic. wifi was fine when i give it back to the person but got it back 2 days ago wifi was greyed out, so i looked at it today and turned out that c5202_rf was the cause. im not getting any signal, its either searching or no service. when i checked *#06# before removing c5202 it went off dial screen. now when i do it, its like it deletes the *#06# and stays on dial screen

You pretty much have to pull them to see what solves what, especially with water damaged boards.
