Autosync not working, youtube app doesn't recognize my google account

[paparazzo79]

Hi guys.
I'm on Galaxy Note Pro 12 tablet with Android Lolipop.
Everything worked okay,until recently, I probably messed around with some google apps, can not remember,I know I did remove some updates in apps which I don't use,forgot which ones.
Now autosync doesn't work,nor manual sync of account,and when I run app like youtube I get error message (pic below).
When launching Google Play Store I can not access main apps window at all,I just get white picture over the screen,so can not reinstall or install any app.
Tablet doesn't recognize my google account but it is there in tablet running,when I want to log in to youtube with my acocunt I get message that "already exists".
Please help me back like it worked before (normal).
As you can see (red arrow) I'm already logged in.

Are you able to remove your Google account completely from the tablet (in the system settings), then add it back again?

 

[paparazzo79]

Did that,same issue.

It might have to do with how outdated that tablet is -- Lollipop is really old (a full 7 versions behind what's current).

You could try a factory reset.

Try resetting app preference, go to settings>apps>3 dots upper right corner tap

Have you tried signing out your account then back in ?

I did tried remove account and log in again, no help...reverts me to that white page issue...

Are you using a VPN?

 

[paparazzo79]

Nope...
I am logged in,I see my account icon on top right corner but I do get this (picture).

My assumption is that probably I have some issue with some service from Google Play Services...
But Google Play Services is enabled and launched.
I did try clear cache of Google Play Services,no help

You tried uninstall the update to YouTube?
Long press the YouTube icon>tap info>upper right corner tap and uninstall?

 

[paparazzo79]

It's not issue with Youtube just, I have issue weith Google Play..as you can see..

 

[mustang7757]

Ahh . Then try factory reset hopefully fixes this

 

[paparazzo79]

Can I somehow reinstall Google Play services??
And how to?

 

[paparazzo79]

Ahh . Then try factory reset hopefully fixes this

Okay.What will happen when I do that?

 

[mustang7757]

You won't be able to uninstall but go to settings>apps>tap goggles play service>clear data then force stop it under storage

It will restore anything that was changed back to default but back up your data as it will erase but try clearing play service first

 

[paparazzo79]

You won't be able to uninstall but go to settings>apps>tap goggles play service>clear data then force stop it under storage

And then reboot,I suppose?

 

[paparazzo79]

The option FORCE STOP is grayed out..I suppose that is the problem??
Google play Service is not launched at boot, perhaps?

There is no option CLEAR DATA.
I think play service is not running for some reason,what do you think?

 

[paparazzo79]

I relaunched the chrome and I got this message.This is not my gmail archgkl...
I think I am hacked.
Here is what I get in google play services.
