How to flash Stock Recovery without PC I'm trying to get back to stock recovery. Currently I don't have access to a PC. A few days ago, when I tried flashing the recovery.tar file via Odin, it failed. How can I get back to stock recovery? I have the recovery file in both formats i.e. .img and .tar. 
Any help will be appreciated.

My Device : Galaxy Tab 4 SM-T531 Android 4.4.3 Stock
