Pokemon Go - Will not load or sign in [duplicate]

I do not know what happened. I do not know if it was an update, corruption of data, or whatever. I just cannot get my Pokemon Go to load with my google account any more. I was level 10, with a good collection of pokemon and items. Hatched a Staryu last night and that was an awesome feeling.

Here is the Rundown:

I start PokemonGO - It brings me to the sign in screen - I tap on "Sign in with Google Account" - Then loading screen pops up - Pauses and a black screen appears, and disappears in like a half a second - then goes back to the load screen with the spinning pokeball - then it says "GPS signal not found" for like a second, then goes away - continues loading FOREVER.

I cannot log in or get into the game no matter how long I let that screen load. I have created a PokemonGO account (the other option instead of google account), but I really hate starting from the bottom. I already had a good collection, some Pokecoins, and a reputation. If anyone can help, then please do.

Before commenting, this is what I have tried:

• Resetting App
• Resetting Phone
• HARD Resetting Phone (taking out battery and holding power button)
• Clearing cache
• Clearing Data
• Turning off and on WiFi
• Turning off and on Airplane Mode
• Disabling App
• Keeping loading screen on for a LOOONG while.

I have done all of this, and a combination of a few of them together.
