Hi Guys,
I know this is a really late response, but I too have been tearing my hair out on this one.
I have an Apple TV Gen 1. It is brilliant, but owing to difficulties with our internet, we had not used it for ages. I now have very fast and unlimited 4G and thought I would resurrect the device. It is updated etc etc and passes its own diagnostics. However, it WILL NOT, under any circumstances sign in. I have had over an hour on the phone with Apple, who concluded by telling me it was probably a hardware fault as the device was so old. However, I don't think so.
I've done all the business with the password + code and been sensitive over the timings, as per earlier posts in this article, but to no avail.
I then concluded that it is because my account has 2fa set up. I cannot switch this off on any of my devices. Undaunted, I thought I would set up a new Apple ID on a new device (spare iPhone, previously wiped) and try that. I find to my horror that even a new Apple ID comes with 2fa from the start, no option!
So, 2 questions please for Apple themselves and for the wider community here:
Can 2fa be in any way suspended for long enough to allow my old Gen 1 ATV to sign in to my account please?
If not, what fix/patch or otherwise is or can be applied to the Gen 1 ATV to make it function again please?
If the answer to these questions is "no" and "none" respectively, then I think Apple should refund me the price of the new ATV DH that I have since purchased. They have rendered their excellent piece of kit obsolete by this apparently know incompatibility and I think it is terrible!
Any help any of you can provide on this would be much appreciated, thank you.
