Note 4 SM-910F can't install any Samsung modified Rom

Hello ! I just bought a Galaxy Note 4 910F 32gb phone from a local carrier (Telekom) and unlocked it so now it is network free and can use any sim. The thing is i tryed with OTA 5.0.1 and 5.1.1 from samfirmware to get a rom working but i can't . I install usb drivers, flash TWRP (latest) with odin and after that i clean wipe the phone for system,data,dalvik,cache (for new rom) . I tryed 3 slim samsung roms on 5.0.1 and none work. I just get a restart after Samsung Galaxy Note 4 logo or with some i just wait on the Samsung glittery logo for 30 min and nothing. I did wipe cache and data from recovery but that won't work. I even changed the bootloader and modem for 5.0.1. and 5.1.1 and viceversa but nothing. The only thing i can get up to boot is CyanogenMod or Stock Samsung. Please help me ! i want a clean samsung rom without any bloatware ! So in the end THE MAIN IDEA is I CANT INSTALL ,,SAMSUNG ROMs '' only CM.
