Does factory reset a safe way to remove TX Pro completely? NO BAN?

[geogechan]

Hello guys
I have recently got an NS from my friend (with TX Pro licence,no ban), I am not sure he had done a clean NAND backup or not. I hope to play online so I decide to remove TX OS completely.
Does factory reset a safe way to remove it ? (No need to restore NAND back up then)
If it is safe, do I need to uninstall AutoCRM first ,and delete boot.dat or do a factory reset DIRECTLY?(I will turn off WIFI first for sure)
Thanks for your support! Sorry for my poor English.

Unfortunately no. You MAY be fine if you do it, but it's not 100%. The only way to make sure would be to have a clean nand back up from before you started using CFW.

No, once you mod you're modded!

So if you dont have a clean NAND backup is there a way to acquire one?
