If you have rooted your Lenovo P780 and thinking to install custom ROM, then you must change your stroke recovery to custom Recovery. TWRP is one of the well know custom recovery. I know a question is arising in your mind What is custom Recovery? Lets make it easy for you. Have you ever tried to install OS on your PC or Laptop? What you do is insert a Windows 7 or xyz DVD/CD and restart your PC. And on the boot screen you see “press any key to boot” and you just processed by pressing a key.
If you never see the press any key to boot on your screen will you be able to install new OS on your device? I think No!
I think you all know how to access BIOS in your Laptop or Desktop, same like you can access BIOS of Android which is called Recovery. For this you need to hold some special key and its vary device to device. If you access your Recovery in Android you will see its like some kind of BIOS of PC with lots of options as well as a factory reset option.
But in normal condition the Recovery menu does not allow you to install a new third party Android OS or ROM, know as Custom ROM.
That’s why we need to change that recovery or stock recovery to a such recovery, which allow us to install Custom ROM. TWRP is one kind of Recovery that allow us to install custom ROM.
