Default [Q] Amoi n821

I have an Amoi n821 phone with a 4.1.2 rom on it and was hoping to upgrade it to 4.2.2 which seems to be several roms. I can't figure out how to flash my recovery as it seems it is the stock recovery with no option to install from sd. I have tried flashing different CWM all of which seems to just come up blank when trying to boot into recovery. If anyone has help or knows what version of CWM or TWRP to install please help. Thanks
