how can i change the recovery from cm12 recovery to TWRP 2.8.3.0 recovery?
now, my rom is cm-12-20150109-INFECTED-yuga

1)in cm12 recovery, apply update olivier's "twrp-2.8-20150108-yuga.zip" , it's error:signature verification failed

2)use fastboot,"fastboot flash recovery twrp-2.8.3.0-yuga.img" , it's error:FAILED (remote: Command not allowed)

3)Flash it using dd,it's also the cm12 recovery
