Note 4 return to stock firmware

hi,

basically I have flashed Note 4 to android 7.1 and now decided to return it back to stock firmware. Checked Samsung Phone Info app and found that PDA Version: N910VVRU2CPG2/ N910VVRU2CPJ2_PJ4. Then downloaded N910VVZW2CPJ2 stock firmware from Samsung which by PDA version looks exactly what I need.
But when trying to flash with ODIN tool, I get 'Secure Check fail: aboot'. And this error links to incorrect PDA version. Is it possible that when flashing a phone PDA was re-written ? And...
