I anticipate that I will, nor the forum will take responsibility 'of malfunctions and \ or damage!
Part One - CMW Install and Root command line
In this thread, I'll describe a simple, fast, and definitely safer than SPFTools.
SPFTools VCOM working on ports that are not always recognized, sometimes give problems also installing special drivers, they are almost always a problem for Windows because of the signatures on the driver.
Closed this little digression for information, we start with the drivers:
Driver Lenovo K3 Note + PDAnet+:
When completed restart the PC and install the utility on the device:
Without this included in your terminal this .zip file to obtain permits Root later:
Minimal ADB & Fastboot + K3 Note Recovery (CWM):
Unzip the zip file and open the file py_cmd.exe and quietly run these commands:
adb reboot bootloader
fastboot flash recovery recovery.img
Perfect! now to get root permissions, there will be that off the device, wait a few seconds and turn it on using this key combination:
VOLUME UP - VOLUME DOWN - POWER
choose zip from /sdcard
Et voila! The device is unlocked and ready to receive new rom and functionality!
Part Two - Install new ROM from SPFTools CWM does not work when
Many with the above guide you tried to change the finding in eom stuck.
With this procedure you can go back, but before we move forward I want to give you a few details regarding the update of the rom:
*- The rom mounted on chinese devices with Play Service support and multilanguage already moddate the seller.
*- Given the above, download a rom 'official' (see NeedRom) carrying the phone in its native state.
*- If you need to download the latest versions from the site VibeUI not download the latest available, sometimes the downgrade is not possible (personal experience).
First, before you go ahead to make sure you have followed the guidance post 100% in the first part of the thread.
Follow the link:
I post the link of a rom in case I tried to see if this will work, even to you. To me it is working well.
In the third part if this rom works almost everyone will get all roms that I find around and decide what to do and what to do.
Before we go on, first remove the battery and attach only the USB cable, then set the SPFTools this:
Set in this way the program.
In step  look for the previously extracted folder and locate the file.
Give the program a few seconds to load the rom, and after leaving it in Download Only Click Download .
Obviously nothing will happen, to make sure that going forward, you can simply insert the battery and wait for the completion of the transaction.
Reinstall the back cover and turn on the device. Give it about 8/10 minutes for the first startup.
Et voila! We are again ready to modding this Lenovo K3 notes!
