    1. Hi Andy,
      Thanks for you reply.
      Actually i bought it in Indonesia last year.
      I did try to change simcard 2x, and complain about the signal problem to the provider (they reset many times). Tried also on sim2 but the result is the same. Once i put the simcard on other phone (iP**ne) and the signal is full bar.
      Please advise, what might be the problem with my s860? Is it the hardware issue?

      Thanks

    2. The different china device and eurro device is the size of Ram if you have 2 GB than you safe to install international firmware but if your RAM size is 1gb than after flashing you must flash china modem to the ROM.
      But sometime modem flashing can fix signal problem that happen on lenovo device, look how to change on this guide http://bit.ly/1mafu2K, you have to rootand use custom recovery to change modem file

  1. hye andy i have same problem after update to kitkat baseband 108 s860_402, before update baseband 102 was good signal stregth. Mine is ROW set 2gb ram. How can i fix it. For this new update is it baseband 109 or some else…without root. Can i rename 102_modem as update.zip n flash via stock recovery lenovo.

    1. Hi,
      The answer is same with above comments, just open the link and follow the guide to change the modem firmware, to change modem you must have root device, or if you wanna flash through recovery you must have update.zip. no you cannot rename it different file with different script
