Hi guys. I bought a Note 5 not to long ago and i decided to flash the marshmallow firmware. After the flashing, my phone isn't able to grab signal anymore. The base-band modem did change and i believe that's where my problem resides. I been trying to figure out how to switch the modem back to N920PVPU2AOI6. Since this one did give me service in china, although i believe the radio was working too hard, thus killing the battery life on the device way too fast. If you guys have another modem in mind that will work much better in China please do help me out with a LINK!
future thanks guys.
