Help Galaxy S5 SM-900F Custom Rom

Hi there guys,

I recently bought an Samsung Galaxy S5 SM-900F that came already rooted with Cyanogen CM12.1 (cm-12.1-20150806-NIGHTLY-klte), using CWM Recovery Philz_touch.

When i was trying to make the updates through OTA, i was never able to update the firmware it was always displaying the old one on the informations of the phone. So i updated the firmware throught CWM Recovery Philz Touch manually, everything was ok, after that i thought to change the Recovery method to the TWRP latest version, it seemed ok that i suceeded.

However when i try to enter recovery mode i can't i'm always stuck with the ODIN mode saying Custom Rom and Knox 0x1 and does not let me to enter into recovery staying always in "Download Mode" .

I also done throught odin the installation on CF-Auto-Root-klte-kltexx-smg900f to be able to enter to recovery mode but if i try to place TWRP or Philz_Touch through Odin it will always get stuck in Download Mode :
