Factory fastboot mode on Huawei devices is a low-level mode used for performing advanced system operations. It is a non-chipset-specific feature available on all Huawei models equipped with Kirin chipsets.
You will need to connect your device in Factory mode, using testpoint then use the Load Factory Fastboot button to enter this mode.
In factory fastboot mode, Chimera provides a variety of useful procedures, though their success depends on your device's security level and firmware version. Typically, older security versions are more compatible with this mode.
For devices stuck in retail mode, a display mode used in stores, you can modify the OEMINFO to exit the demo mode and restore the device to normal operation. Additionally, you can convert your device to a dual sim using this procedure.
Before proceeding with advanced tasks, such as the Modify OEMINFO Chimera will make a backup file automatically, it's possible to use the "Restore Sim State" option to restore the original backup later if needed and avoid potential data loss or corruption.If your device is locked to a specific network, the "Network Factory Reset" option can be used to reset the device's sim-lock profile to the default.
Finally, you can use the "Read Cert" procedure to copy the device's certificate, including its IMEI number, and the "Write Cert" procedure to transfer it to another device with the same model number.*
