For Samsung frp, I used eft pro and it worked

For Samsung frp, I used eft pro and it worked. Android 16 sm A176v(probably among the more difficult). Rent account access for only $1.5 for 4 hours from a vendor on this site. Download &install it first from the eftprodongle site. Switch from "dongle"to "account" after opening the app. Insert the user/pass you rented. Took a couple of hours from knowing nothing to figuring everything out to access it. Hopefully this saves someone the same time and effort it took me.
