kostelecronics is right, but if the phone is not dropped or water damaged, then heating might solve.
i did it like that many times and it works. 2-3 months have passed,

at least try it

if phone was water damaged check R9_RF(tested solution by kostelecronics)


also check U1001_RF, if getting hot replace it(tested solution by Wites)
