A pre-installed custom ArcaneOS Pixel 4a phone surfaced in 2021 and was used by the FBI for global operations to trap criminals. After 2 years, the Pixel 6a phone pre-installed with FBI customized ROM is exposed again, the device is pre-installed with 3 apps, and the BootLoader cannot be unlocked just like the previous Pixel 4a.
The internal version number of this FBI customized ROM is TP1A.220624.021.A1.2022121400, which is similar to the version number of the September update of GrapheneOS and may be a customized ROM based on GrapheneOS.
The FBI custom ROM for the Pixel 6a includes the September security patch, the baseband version is 220720, and the BootLoader version is bluejay-1.2-8893284, so the device was produced immediately after the Pixel 6a was shipped.
The whole initial setup process is the same as a normal AOSP-based custom ROM, we first select the language. Then we enter the date and time information. Then it will check the SIM card. After this step, we will be asked to create a passcode for the device.
Although the FBI is a US agency, the device has a CE barcode on the back and the model number is G1AZG. According to the Google Tensor source code, the G1AZG model number is specific to the European Union.
