How to flash stock Rom with format everything

[yken]

I have a P550 tablet, using Odin i installed stock Rom but it did not format, it did not delete everything in it. Using stock recovery factory reset does not work either.
School It managers disabled entering settings, so i guess they did something to tablet not format inside but i flash Rom still cant format it. How can i fresh install stock Rom?

Just factory reset in recovery. That's all you need to do to go back to factory fresh.
You dont need to do anything else, not sure what you're expecting other than that?

I learned there is a security program, wmware watch in the tablet, it does not permit to factory reset. I can flash Rom but i dont know why flashing rom does not erase things.

I've never heard of such a thing and there's no reason for it to exist. Are you sure you have used factory reset in recovery?
Flashing a rom does not wipe the data partition.
You need to factory reset in recovery to do this.

Mdm does not allow factory reset. Google this.

Yes I'm aware of mdm, but have only ever come across this on demo devices.
But that's not what you posted.

Also it is only stock recovery that implements mdm.
If you install twrp then factory reset using twrp it will remove the restriction.
That is the only way I know how. However this may require OEM unlock enabled, of which it seems you can't do.
