help!!! installed my first rom and now their is just a black screen after boot logo

i had an s3 which was already rooted and i swapped roms regularly but i didnt root it.i sold it and bought a note 3 and wanted to root it.it was my first time rooting and i used odin3 and it worked ,i checked root with root checker,i installed twrp through a playstore app called' twrp manager(root) ' or something like that.it said failed but there was an option to test it anyway so i tried and twrp recovery worked so i didnt look into the 'failed' message

i downloaded cyenogen mod 12.1 for note 3 to get android 5.1.1 and i also downloaded gapps,now i wiped dalvik cache,cache,factory reset but also system by mistake so im not sure if that caused the issues.i wiped that stuff and flashed cm12.1 then gapps and restarted,BAM shows samsung galaxy note 3 sm-n900 info then just a black screen,i restart same deal,re-flash but still same issue

i downloaded a rom called ressurection remix v5.5.6 and wiped then flashed and same thing,phones info logo then black screen

please help me. i have note 3 sm-n900
