As the title says
I had to do a factory reset because I started having problems with the NOS4 update.
After performing a factory reset, my Google account was locked by something called “advanced security program”.
I don’t remember activating it, it disabled 2-step verification and I literally lost access to my Google account
Since I only use one device with my active account, I don’t have another trusted device.
If you consider performing a factory reset, remember to deactivate your subscription to the advanced security program. If you’re considering a factory reset, remember to disable your Google account’s advanced security program subscription.
