HOW TO INSTALL :
To install this custom recovery, you need SPFlashTool program which only available on winblows os platform so … really sorry, I cannot support it because I never use and don’t have winblows. You may refer to this tutorial : MT65xx Flashing Tutorial it is very well explained by Bruno Martin and try to find Flashing only part of the ROM part on the article to flash only the recovery image part.
Please be really careful using SPFlashTool, especially when flashing ROM not for your device, since it may bricked your device forever.
