Looks like it's 2) or may be 1) because my phone is 100% functional.
I just hope GreenAddress people are reading this forum and will eventually try to solve my problem.
According to
bitcoin.org, transactions from GreenAddress have to be approved by both you and them.
Here's what they say about recovering your coins, in the unlikely event that their site goes down:
Should our system be taken down or disappear, sleep safe with our automatic presigned transaction (nLocktime) allowing you to simply wait for your selected expiry to get your funds!
Therefore, it looks like their 2fa system is broken and your coins are safe. For support, email them at
info@greenaddress.it.
