Cannot flash recovery

[Matt 123456789]

So, I rooted and tried flashing both TWRP and Clockwork but nothing, I can't boot the recovery.
I have heard that the bootloader is unlocked on GT-I91965 but when I flash the recovery with ODIN it does a mini 5 second process
and says "PASS!"
I don't know what to do :/
Any help?

After flashing the TWRP , what is the step what are you doing ?
Autoreboot ? That wromg.
On Odin uncheck autoreboot,
Flash TWRP with Odin, disconect the USB .
Reboot with the 3 Buttons into recovery.
If you boot into System ,you must start again with flashing the TWRP.
