  1. Hello Andy. I have downloaded both of this modem and also installed. But my s960 have some difficulty's to get 3g network. Do you have any other modem for this model. Or any solutions for this issue?

  2. Hi andy
    The phone is already rooted. And mob uncle also installed. So what we can do with mob uncle.
    Actually the thing is that the phone didn't get WCDMA when it's startup. if the network mod is set to "GSM only" than it will detect the signal “gsm”. And the mode is set to” WCDMA only” it will appear no service available. And the signal strength bar will show Red Cross mark. But it will detect the network provider. So if you can do anything with mob uncle please give me the instruction
    Thank you

    1. To install modem file to your device you need a custom recovery, twrp or cwm. Custom recovery for android 4.4.2 cannot be use for android 4.2.2. That why i warm you about that, but modem file can be use for both operating systems

  3. Hi. Do you have the original modem file for V102? I cannot update via OTA because of the changes I made in the modem. Installing updates gives me an error saying there something wrong with the modem

    2. so i think you need to contact the Lenovo because i just share their china modem and give Lenovo user to experience change their modem for better signal, but if modem files that i share not fix the issue than i think you should contact the Lenovo

    1. that a spam web, website that give false information and only contains adv, if you click the link provide you will be serve with another link and you will never found the ROM. if you dont believe me just click it and beware of virus.

  5. Thanks for the info. I have a hunch that it is not legit coz I don't see any lollipop custom rom in XDA for vibe X that's why I asked here since this is the only safe source of rom for my device. Do you think there will be a lollipop update even for custom rom?

  6. tnx for this file again sir, at first my s960 just automatically updated to chinese version and my phone fucked up and then i just came into your other post of rom (the one pre-rooted custom rom by baralajbi),afyer flashing it,it works fine and smooth but rhe problem of that rom is weak signal. but now using this file it just boosted my signal reception.your a big help!!! thank you so much…
