That did the trick.
So after softbrick on my HTC one I relocked my bootloader with Fastboot with the command: fastboot oem lock
Then I chanced my CID to HTC__001 with the command :fastboot oem writecid HTC__001 (two underscores)
Then did run this RUU http://www.androidruu.com/getdownloa...signed_2-1.exe
THIS WILL WIPE WHOLE PHONE!!
This will take about 10min to run( so don't stress like I did
This will reboot device ( 10minutes of booting time)
Next is unlocked the ''RELOCKED'' bootloader with the ''HTCDev way'' http://www.htcdev.com/bootloader/
Next I did flashed custom Recovery with the command: fastboot flash recovery name_of_your_recovery_here.img (also see this link for steps to go http://youtu.be/qpj6dEMn9dw?t=12m23s
Next I did is Flash my custom ROM (in my case viperrom witch have supersu inside )
And last did go super SID: fastboot oem writecid 11111111
And I am good to go now!!
Thanx for all the help!!!!!!
