LG G4 H815 no sim signal I have just flashed a Europe firmware meant for H815 to H815T. In doing so I have upgraded from lollipop to marshmallow. The firmware is so smooth and fast except that there is a big problem. NO SIM signal. I know that this is because of some base band problem. Can you guys please guide me on what to do?

Thank You
All the firmware are not Fully Stable. May be the firmware you installed doesn't have a sim support. You can simply change your custom firmware or get back your original firmware. You can have a stable Rom from Cyanogenmod. It really provides stable Rom's and mostly stable one's.
