so long story short i havent been in the rooting game at all in around 4 years so i tried to downgrade my phone and it got disconnected in the middle of the update and now it wont get off recovery, splash logo, and download mode. it WAS on 6.0.1 (cant remember which update) but i tried to reflash a pf4 stock rom in odin and it wont do anything after it says aboot.mbn. in recover it says cant mount /system. download mode is as stands

current binary:samsung official
system status: official
reactivation lockff
qualcomm secureboot enable (csb)

Have you tried to Odin back to PB1 and start over rooting upgrading, etc?

Put this pit (https://www.androidfilehost.com/?fid=24052804347765167) in the pit tab in Odin and put the pb1 tar (https://www.androidfilehost.com/?fid=24438995911970571) in the ap tab in Odin then try to restore
