I own a factory reset fully updated Samsung gt-s5301 that won't log in with my google account, despite being able to log in with other accounts and having internet access. I tried turning two-step and allowing external logins to my g-acc, I even tried another google account. it just won't log me in
Not sure what's blocking the process of logging in however these may help.
There is quite a few hits via a Google Search too.
I wish you all the best.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
I also tried Googling this, but without luck!
I tried all the steps your provided, but nothing of it seems to work
I also tried reinstalling its original firmware through Odin mode, but it may be beyond my knowledge despite following the instructions for doing so.
