Samsung Galaxy S5 Root SM:G900F Problem

Hello to all members,
I have a problem with my Galaxy S5. I Root my device but one month after Rooting I did a mistake. I delete the folder Super SU from my phone memory and now I have unroot my device with lollipop 5.0. I try to Root my device again looking this video (https://www.youtube.com/watch?v=iBNGeppOzGI) but when I go to install TWRP Recovery I have this message in Odin :
<ID:0/006> Added!!
<ID:0/006> Odin engine v(ID:3.1005)..
<ID:0/006> File analysis..
<ID:0/006> SetupConnection..
<ID:0/006> Initialzation..
<ID:0/006> Get PIT for mapping..
<ID:0/006> Firmware update start..

<ID:0/006> recovery.img
<ID:0/006> NAND Write Start!!
<ID:0/006> FAIL! (Auth)
<ID:0/006>
<ID:0/006> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
If I try to continue the process like the video, in 5:08 minute of this video my device shows only “recovery booting” and didn’t show the other two messages below. After this Fail Process my device didn’t have the TWRP menu to Install SuperSU again. I can’t understand this problem guys because when I Install lollipop 5.0 I choose wipe data/factory reset and wipe cache partition so I don’t understand why this process Failed. Any information would be helpful. Sorry for my English is not my mother tongue.

I agree.

The group that made this need to be where you get support. The times I needed to do this had me reading at XDA as Kees noted.
