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://forum.xda-developers.com/leno...8/post52947423
for a list of modems I had problems and no problems with.
Does that solve the problem ?
