Kv Flashing Error

I’m not new to flashing kv’s, but for the first time when I Flashed my new kv to my xbox, the serial # changed, but the Console ID stayed the same as the old one. Of course it says im console banned.
+On flash 360 when I try to redo the steps, when I press “A”, Then “B” it only shows up to ignore and continue once then “A” to begin instead of saying it twice then “A”
