Okay, I don't understand wtf is happening. I've gotten the Android 6 update for the fella's phone. I ran it, all went well. After restart, I choose language, country, etc and get to the "log in to your acct" screen. Enter email & password. It then says it wants to send the code to THIS phone, via pull down notification, which is NOT set up yet???
There's no way to get the code because we aren't even to that point that I have anything installed. So, I chose, "I don't have my phone" & it said to use a browser & go to a specific address (which I did but it didn't keep it in my history?) , after logging into Gmail. I wasn't sure if they meant to use another tab because the directions are so weird. Once there, it said it didn't recognize this laptop so stopped the login. I rang him and asked him to login on his laptop and check for messages from Google. They'd sent warnings asking if it was him and I had him click, "yes, it was me". But he didn't get any codes and I didn't have a choice to send them to his email instead. Now, I'm locked out for trying 4 times.
FFS! How do I get past this? It's ridiculous.
PS: I rang this phone just to see if it was receiving anything and it rings through fine.
Wait, I'm confused. So you were setting up a phone for this other guy? Why can't he set up his own phone? And how were you able to call him if you hadn't set up his phone yet?
I'm not sure how you'd get out of that jam, to be honest. You'd probably have to call Google directly. Yours isn't the typical use-case at all (in fact, your use-case seems hilariously close to the use-case for a typical scammer, so it's not surprising and kind of good actually that Google shut it down after you failed the authentication 4 times in a row).
