Do you currently have a custom recovery on your device and able to access it? Or are you referring to the stock recovery?
When you say you flashed CWM are you talking about the recovery or the rom?

Thank you, i already installed philz recovery and was able to install cyanogenmod
now everything is ok with my device, philz recovery saved my device

The error means you didn't patch the recovery.img with loki_tool before you flashed it. Read the manual installation procedure found in the CWM recovery thread in the Original Development section.

Yes, I know but I'm not the only one who has this problem.
The question is : How can I fixe it without re-flashing the hold stock rom (1,2Gb) with PC and lost root ?

If you can get it to boot into the system, then you should be able to fix the problem by following the manual installation instructions using loki_tool. You can find those instructions on the CWM thread.

TWRP Boot error / Recovery error

Currently i'm on TWRP 2.8.6 / Whenever I flash TWRP 2.8.7 or higher version, recovery is not accessible. normal boot is ok. but can't boot in to recovey. it says "Secure Booting Error! Cause: boot certification verify" . But i can boot in to system.
I reflashed TWRP 2.8.6 and recovery is accessible again. I tried flashify/ TWRP manager and Terminal method. all are result in "Secure Booting Error! Cause: boot certification verify" error.
Does any one know how to fix this? Thank you!!!

yes. same result. actually I was trying to flash TWRP 3.0
Then Boot secure error message appeared when trying to go to recovery. then tried 2.8.7 . yet no luck. finally flashed 2.8.6 which phone had before trying TWRP 3.0
then everything is OK. I followed instructions to update to TWRP 3.0 yet this error occurs

Are you downloading the *.img files directly from TeamWin, then checking the md5?

Hey, my D855 is running cm13 now. I can access recovery mode but whenever I try to boot into download mode I get " secure booting error". Any fix for this ?

Is your device rooted and custom recovery is installed? If so then which recovery and version it is. Are you able to boot into system. Tell whole detail.
