Unlock carrier codes.. Is there a post that has unlock codes for free? i need for my zte blade z839 i think it is. im stuck at the google setup after hard resetting it as i bought it used.
 
that will not unlock FRP (factory reset protection)....you will need to contact the previous owners to get the info so that you can change the account info.

the only other way is to go down to your provider and show proof of ownership. they should be able to bypass frp for you.

this is why i always stress that if you are going to buy a used phone, do so at your provider......ie like a verizon store. and then make sure everything is good to go by turning the phone on and try and set the phone up before you actually hand over the money. this way if there is any issues you can get it straight there. then you can ask your provider to add your phone.

there is not much else you can do at this point.
 
Next time you buy a used phone, first have the seller remove their account to avoid FRP:
1. Remove any PIN or swipe pattern for the lock screen
2. Go into Settings - Accounts and remove all accounts
3. Then factory reset the device.
After that it shouldn't ask for the email and password with Factory Reset Protection.
