Red Wolf Recovery is custom recovery based on TWRP source code however some things are working here slightly different then you might expected. The main objective of this project is to provide stable recovery with features which you have never seen before in a recovery and which have not been accepted for adding to the official source code of TWRP. This recovery is also first recovery on the world with password protection.

  • Based on TWRP version: 3.2.1
  • For devices: YU Yureka Black
  • Authors build: yshalsager
  • Developers: @ATG Droid & @dadi11
  • Thanks: z31s1g (for the base of his theme), Ray Li (For his useful advice in the beginnings), osm0sis (for his image scripts), etc.

Please remember that recovery with password protection isn't still a full protection for your phone. Red Wolf can only prevent unauthorized access to your device from recovery. But your device can be still reinstalled using fastboot or Miflash.
