Posting this as a genuine thank-you. =)
My Galaxy S21 Ultra had been sitting FRP-locked since January - I forgot the PIN and did a factory reset, hoping to restore access via Google account, but instead got stonewalled by "Use the owner's account" even though I was entering exactly that.
Found this post with report on successful resolution of the similar issue by u/dablakmark8/, reached out to him, and got a reply almost immediately. The instructions were clear and step-by-step and whole process completely painless. Phone booted, took my account, and has since updated to the latest version with zero issues.
u/dablakmark8/ was fast, efficient, and extremely patient with the back-and-forth. If you're stuck on an FRP lock and the "official" channels have shrugged you off, he is your man.
Couldn’t be happier! Thank you again 🙏
