Unhappy [Q] SPH-L900 wont boot issues

So I was running 4.3 and was rooted on my note 2 on sprint. I had SuperSU and I did a unroot so I could upgrade to 4.4 I unrooted then rebooted then installed 4.3 then things started to go bad. I can get to download mode, but it wont boot past Smasung GALAXY Note II splash screen. Can't even boot to recovery mode. I have used ODIN to flash CWMR, TWRP, stock rom. And nothing works, if the image has a sboot.bin file, ODIN fails everytime. When I flash to correct stock rom ODIM passes but when it boots it boots to the a firmware update error but Samsungs kies just says connecting ... and doesn't ever connect. I don't know if i hard-bricked or soft-bricked my note 2 or if I am just doing something wrong. PLEASE help me I miss my phone lol.
