Hello guys i have a S21 plus just curious to root it. I know that rooting will make secure folder unfunctional and tamper knox. I have also successfully rooted A70 phone and also unrooted it back by flashing the stock rom via Odin. After i restored the stock there was also an option to lock bootloader again. Well my question is that if we unroot phones back by flashing stock recovery rom and lock bootloader will the phone be at its original state making the knox security like before. Also can it receive updates normally as before? Also i have heard that at service center they use the same odin to flash recovery rom in case of software issue. So is odin safe??
If you flash the correct firmware according to your modal and country, No issues. But still I will recommend you to visit Service centre to avoid the risks. Rest everything is upto you.
