Hello, it means for unlocking these models need to have a Z3X account with server credits on it.
Server Credits enable you to unlock the latest Samsung & LG phones by reading the unlock codes from the phone safely and quickly - without the need to root (void KNOX flag) and risk of bootloop (take 5-15 credits, depending on model).
Also, starting from 37 versions of Samsung tool to repair IMEI, and some other operations with phones you need to have an account with credits on it, to can authorize on the server. The number of credits in the account does not matter, but must be more than zero. It’s free, credits will not be charged.
Without this, you won't be able to use the new solution.
Here you can read more details about using credits.
You can buy a new credit account or refill credits to an existing one you have. Inform your sales manager about it while ordering the item. Otherwise, the system will automatically create a new account for z3x credits.
Please be attentive as there is no possibility of combining credits from two different accounts.
- If your seller is not present in the list, you buy credits at your own risk.
- Do not share your credit account password with anyone else.
- We recommend you to attach the credit account to your z3x card immediately after purchase.
These simple rules will help to save your time and money.
