    1. Hello,
      When you connect phone to your computer, does flash tool recognize your device? Does it show any progress bar when you connect?
      If not then your usb vcom driver not installed properly so you need to install driver again.

  1. Hello there,i need your help when i proceed to step 6 there a notice pop up saying about TMP and flashtool thing or something like that and tried change the download only to firmware upgrade and its working fine but im a bit worried coz i don know what im doing.. am i doing it right ? and one more thing is when i tried dial ####7777# an ERROR pop up saying " CAN NOT CONTINUE! EasyImage code is not set! .. is it necessary for me to dial that code ?

    1. hi,
      you have done the right think, PMT Changed error can be fix with pressing firmware upgrade button instead download button.
      and for dial ####777# it for factory reset, if you device can turn on normally and nothing wrong than the code not necessary

    1. that guide installing custum recovery, which is TWRP. and it not only compatible on 4.2.2 but it also for 4.4.2 Vibe UI 1.5 using 4.4.2, you cannot change system file (wirelsess firmware) without rooting your device, and rooting device on lenovo it need you to install custom recovery.
      anyway thank you for visit

    2. I see your point, however the guide you sent me says that will brick the device with android 4.4.2. Can you post the link here to a guide for the install of Custom Recovery on phones mounting Android 4.4 ROW_S305? Thank you

    3. yes because it modified system files, every modify to system files have possibility to brick your device no matter you use 4.4.2 or 4.2.2, the guide i give you is android 4.4.2, and i don't have link to install custom recovery for S305 it global for android 4.4.2.

    1. unfortunately, I have upgraded my system android from 4.2.2 to 4.4.2; Upgraded 4.4.2 version is Chinese (i changed the language into English but, its system is Chinese) & I could't find any google play store and having a lot of problems to install Viber, Whats app etc. software's. Please help me out, I am really in danger.

    2. yes, official firmware for Lenovo is divided into two type china version and international version, china version only have 2 language english and china only but international version have many language and also have google play store.
      so the solution for your problem is reflashing with international version firmware follow above guide will flashing international firmware to your device.

    3. Thanks for your reply. I have tried to install the driver "USB VCOM Driver" but, I could't able to install it. I have followed few of the procedures as suggested by blogs, YouTube etc but, could't able to install it. Can you please give me the driver link "USB VCOM Driver" and also tell me the procedure to install it? Thanks.
