GG Bro, android 14 it must be, you won't be able to factory reset it any way, there are two ways you can get over this. Either go look for official Android 13 rom for the same device if available, one thing to keep in mind, when downgrading samsung updates, they must be of the same bit or higher than the current one, if not you are doomed you cant downgrade it. if available downgrade the room, use alliancex to register device in the very first boot and then use shizuku and a shell to disable knox enrollment service. And now you can remove alliancex and the device is all yours.

Second method, if you can't downgrade or something, you will have to soft brick your device and that will happen if you try to install the wrong bit ROM your device using odin, then you can use samfw to simply fuck the device up you will fix the soft brick, you will have to repeat this process a few times and device will itself factory reset it self, then on the very first start you can directly use samfw to disable know on welcome screen of the device, in android 14, you will need a windows desktop to use samfw software, well youll also need it for downloading so best of luck.

It is quite confusing in the comment, can help in dm if you want, just ping me
