Hi. Follow this link: http://xdaforums.com/lenovo-p780/development/how-modems-t2757923
Go there, make full backup of your rom, then flash this modems am see what modem is good for you!
Have the same problem.
Chinese model, flashed ROW, and regardless of Vibe or not on top of it installed, my second SIM doesn't work.
After testing with different modems, I came to the conclusion that whenever I install a modem that works 2100 and 900 Mhz WCDMA for SIM1, then SIM2 refuses to work.
After installing a modem for 2100Mhz WCDMA only, it should work.
See my post http://xdaforums.com/lenovo-p780/help/test-radios-4-row-t2761568/post52947423 for a list of modems I had problems and no problems with.
Does that solve the problem ?
