CVE-2018-7911 Explained : Impact and Mitigation

Some models of Huawei smartphones, such as ALP-AL00B, BLA-TL00B, Charlotte-AL00A, and Emily-AL00A, have a security vulnerability called Factory Reset Protection (FRP) bypass. This vulnerability allows an attacker to bypass the FRP function by logging into the configuration flow through Gaode Map and performing certain operations to update the Google account when reconfiguring the device using FRP. This effectively bypasses the FRP function.
