If no mathematical relationship exists, developers resort to brute force. The idea is as straightforward as it is impractical: try every possible 16-digit combination until the correct one is accepted. The 16-digit code space is astronomically large, ranging from 0000000000000000 to 9999999999999999 , which is possibilities.

Some scripts attempt to be smarter, using the Luhn algorithm (the same checksum used for credit card numbers) to drastically narrow down the possible valid 16-digit codes. One user was able to test all possible 16-digit codes that satisfied the Luhn algorithm in just 45 minutes using Python scripts. However, even this approach often fails because modern Huawei phones have shifted to 16-character codes that include letters, which increases the possibilities billions of times over, making a brute-force attack virtually impossible.

In theory, a user could run this tool, receive the code, type # followed by the code into the phone’s dialer, and instantly carrier-unlock the device without needing permission from the original carrier. For a few years (circa 2012–2018), this became a popular DIY method among tech enthusiasts and second-hand phone buyers, bypassing carrier fees or unlock eligibility waiting periods.
