I rewrite this from boycracked, Ishtiyaq Husain, Techolaty.net, XDA.

--------------------------------------------------------------------------------------------------------------------------

WARNING: 

FOR ADVANCED USERS ONLY. I WONT BE RESPONSIBLE IF YOU BRICK YOUR DEVICE DUE TO A POWERCUT OR YOU MISSED ANY STEPS.
This method is actually for lenovo a6000 but for a6000 plus after flashing we need to recover the CWM backup of stock kitkat of lenovo a6000 plus.
Flashing requires a UPS backup or a laptop which won't shutdown in the middle as this process requires 6-8 mins

Note 1: SW updates

 All OTA updates work for Lenovo A6000 as we have flashed the original stock rom of lenovo A6000. But as there is no stock rom available on the internet for lenovo A6000 plus. The minor firmware updates wont work for Lenovo A6000 plus it gives a status 7 error even after flashing the stock recovery, however the lollipop update gives an error status 14 but works fine.
On lenovo A6000 plus Minor sw updates won't work on KitKat. On lollipop I have not tested as there is no minor update till now for lollipop.

Note 2: IMP During flashing 

i. Do not unplug the usb cable if after plugging in the phone in download mode the adb interface driver is not installed by windows and flashing is started. Its normal.
ii. In lenovo downloader it will seem like the flashing is stuck after some seconds but it is not so the flashing is going on so DO NOT UNPLUG THE USB.
iii. In lenovo downloader in the step tab only the firehose is seen but it doesn't mean that flashing is stuck. Let the process finish without disturbing the USB cable. It will require 6 to 8 minutes or 15 minutes max.

2. Download the recovery file and place the backup on external sdcard Link3 techolaty cwm backup
3. Boot into cwm by fastboot Link2 youtube and recover the cwm backup from cwm recovery.
4. Reboot your device from the same custom recovery after the restore is complete.
