OMG. I am going through the same thing. Ready to pull my hair out. Did you ever find a solution to the CCK Dilemna? If so, please share and, take me out of this misery

No, sorry

Contact Boost Mobile again: Explain the situation clearly and insist on getting help to unlock the phone. Emphasize that both the carrier and the manufacturer have confirmed that the CCK code request is related to unlocking the device. Perhaps the previous representatives of the company did not know the exact steps to follow for your phone model. Visit a Boost Mobile store: If possible, visit a physical Boost Mobile store in your area. Store representatives may have more experience in unlocking devices and may be able to find a solution or redirect the issue to the appropriate department. Speaking of stores, can you tell me where you can buy a driver's license, like this place, I think there may be something for our country? Contact TCL: Since TCL is the manufacturer of your phone, they may have more information about the unlock process or any unique requirements for your device. Contact TCL support directly and explain your situation. They should be able to help you understand the unlock process or provide additional assistance.

A CCK code, also known as a Control Code Key, is a numeric or alphanumeric code used to unlock or remove network restrictions on mobile phones. It is often required when switching to a different network provider or when using a different SIM card in a phone. The CCK code is specific to each mobile device and can be obtained from the original network provider or through third-party unlocking services. It allows users to use their phones with multiple carriers, offering more flexibility and freedom in choosing a network.

I have a TCL Flip bought directly from Boost Mobile. I want to give the phone to my granddaughter to keep in her car. I have asked Boost to unlock the phone. The Boost reps keep telling me it is unlocked, however when I insert the sim my greanddaughter received from her carrier, the phone keeps asking for a CCK Code. It appears to be an 8 character (min), all numeric code.

The Boost people keep telling me they can't help with this, yet the people from my granddaughter's carrier AND even the manufacturer, TCL, tell me this is a prompt to unlock the phone. I've spoken with 5 different Boost agents and am getting nowhere.

I have already tried the thing with removing the sim and doing an "Update software" through wifi. An update applied, but it did not solve the issue. I have also done a reset on the phone.

I've already google it and there just isn't much info out there on it. THX
