    1. Hello,
      For vibe ui v2.0 i still cannot make google play to work because it different with vibe ui v1.5 but 8f you want we can try vibe ui v1.5, but it up to you. Leave you skyoe contact and i will soon contact you once i am available
      Thank you

    1. "If you google, "Code 10", you will find that on a Windows system it is an error code generated by the Device Manager "because it can not start a device". In a nut shell, the most likely cause for this is because the device was not properly installed with the right drivers.

      If you are running Windows, you can try to use the attached file called USBReview to see what device that is as you know it is your phone. Basically, with this program you can remove all the old drivers and start all the driver installation again.

      Try to find your phone either here on xda, on the web or contact your phone's manufacturer – you need drivers!!!

      Good luck, Mr. Phelps at xda dev"

  1. i might want to ask is if there are a big difference between Kinguser and SuperSU applications.. does this 2 application can be installed together? or just need 1 of this applications? im very curious about this 2 type off root apps

    1. Hi,
      Actually is same application, kinguser is most use by china firmware and supersu is most for international and android 4.2. Because i heard it difficult to install supersu on android 4.4,
      Just install 1 supersu or kinguser, they both have same function.

    2. Hai Andy, need your advice.

      Officially upgrade S939 from 4.2.2 to UI 2.0 4.4.2 using Lenovo Smart Assistant, after upgrade and install gapps my phone always hang. Cant swipe to unlock screen even using power button. I need to press long power button to reboot than only can be use.

      If i flash using the firmware above, who'd be happen a same thing or need special tool to repair it?

    3. @penaga,
      i hope it not.
      but for your problems are you already try to factory reset your device first ?
      because i think can't swipe to unlock problem it look like that your device is lag and need to reboot.
      this above guide is also use Android 4.4.2 so it not Android 4.2.2 if you wanna install Android 4.2.2 you can follow this link http://bit.ly/1wEpWA5

    4. Andy, already done factory reset delete all user data, wipe cache and wipe dalvik cache.. It will happen after my phone on standby mood.

      For yr info previous version jelly bean 4.2.2 officially upgrade from lenovo to VIBEUI V.2.0

    5. if i root my mob s898t+ ( golden warrior ) with the firmware which you mentioned in the topic
      i will work ????
      if i had done it can i re root my warrior to the last firmware ????
      moreover s898t+ don't receive Hsdpa signal if i root with s939 firmware it will receive Hsdpa signal ????
      thnx best regard

    6. Hi and thanks Andy, for your detailed tuturial.
      Here we use to say that wisdom doesnt take sapece to be stored.

      One question before deciding to Update/Root my S939,: Can we install other languages after Root/Falsh ROM? For instance Portuguese?

      Thanks in advance!

    1. i am afraid there is no new ROM for your device, suck shame great device with great specification but still using jelly bean ROM. try search at needrom.com for custom ROM, official they not release any new ROM again
