Big Thanks for the Tutorial. If anything happens wrong while rooting like boot loop or something worse, is there stock rom or firmware to flash or push through adb ?

Does the rom link given here unzips perfectly?

Because i saw in another thread of Lenovo K8note titled firmware, users unable to unzip due to error in system img. Also downloading from baidu needs a user id. If its possible could you or anyone else reading this upload it in some other online storage drive. Im little bit worried about getting a worse situation while rooting. Even if it goes wrong i can use the stock firmware to make it back.

Yes, I think so. Anyhow there is no need to unlock oem again if you are flashing the rom via TWRP. Anyhow let someone confirm about it.
