    1. Hi Andy,
      The above error msg may cause by Android_Gadget_CDC_driver, after I tried to connect it alerted for CDC driver so I installed it and work now.

      I want to know whether it works for Asus Zenfones or not since I browsed via ROOT explore I cannot find MDDB in phone system as I did on Lenovo.

      Could you please advise for any other brand such as Sony Ericsson, Samsung, ASUS Zenfones, etc. Does it work for these models?

      Thanks for your sharing!

    2. Oic nice work you done. Actually this guide is for mtk device only and sadly asus, samsung or sony don't have any device with mtk processors. And for another brand i still don't know how because it need me to find out first than study it. So sorry cannot help you more

    sory for bad language

    1. been trying to install maui meta v6 on windows 7 using winzip ( use evaluated version ) but its displaying " Error 1311.source file not found:"……….upload ASHAKAAS.INDONASIA…………….Verify thst the file exists and that you can access it. PLS HELP ASAP.

    1. ok, i already see the video, and i think it not on meta mode. because on meta mode your device not known as Lenovo S660 but known as PORT. so it will not show as windows icon. Turn off your device with battery, then connect wait until charger icon disappear then press power button, exact 2 second release power button and your device will be on META mode

  4. OK..thanks I fixed nvram error also..and I gonna install new ROM,they said wipe system also.can I wipe system?there backup this stock ROM….I need what items to backup like system,data and thanks for my mobile getting back signal!!!

  6. I have (No Signal) error and Invalid IMEI and in Wifi i find NVRAM WARNING ERR= 0x10.

    Handset model is Lenovo S850
    Android Version: 4.4.2
    Baseband:S850 ROW V108
    Build Number S850_ROW_S207

    When i connect MTK Droid, it should blue light. Pls Guide

    1. Yes My Phone is Lenovo S850.

      After following your guide (, Phone is not switching on – No response (Black Screen). Now again i have re- flashed it and restored IMEI. And stuck at same – No signal and NVRAM wifi error (But WIFI works)

      Further guide me….

      Handset model is Lenovo S850
      Android Version: 4.4.2
      Baseband:S850 ROW V108
      Build Number S850_ROW_S207

    2. The prosedur is, reflash the phone, then fix the nvram from link i has give to you. Then after fix the nvram then restore imei using maui meta. Have you select emmc on step 3 from the link i give to you? The link i give is the only way how to fix S850 signal problem, S850 is special only restore IMEI will not back your signal

    3. look the step by step, first fix the NVRAM so you got the signal back, after that look is the wifi still show error, if still error root the device than try to fix wifi error. if you still not have signal why you fix wifi, the most important think first. fix signal

    4. Andy, I reflashed and then download Root Explorer to Fix NVRAM. In Root Explorer i am unable to find any file in Data Folder (It say you have root your phone to view the file). Please Explain me clearly. I am unable to fix my phone.

    5. first is fix Signla, using S850 flashing NAND guide i give you, second is fix IMEI using this guide third if you still have problem with wifi errx10 than follow the guide from xda, if wifi no problem than no need to follow xda
