Wat is custom recovery ?
Custom Recoveries perform the same tasks as the stock-Android recovery with a few additional features, such as the ability to make full system backups, and flash custom roms.
1. A rooted phone
2. A custom recovery
Flash recovery without PC:
1)You must have to be rooted
For rooting check this link
2)Download the recovery and place it on EXtSD card.
3)Then Boot into Recovery
Recovery: Volume (-) + Volume (+) + Home + Power
4)Select install from sd card and navigate to recovery.zip
5)Whoa You have installed a custom recovery.
You can also flash recovery via odin (attatched below) but flashing without pc is lot easier.
Now you are ready for flashing custom roms.
You got to think about it once again.
Point 1: why?
Point 2: internal also works
Point 3: how should this work? You cant do this with the stock recovery so this is senseless.
Point 4: same as 3 this wont work with stock recovery
sorry aint there enough threads describing several ways to install a custom recovery
