It supports a wide range of Huawei models and can perform various service operations, such as removing FRP or Huawei ID, reading or writing firmware, enabling downgrade, etc. Sigma Key can also unlock Huawei devices via ADB mode or software testpoint mode.
Unlock Huawei via ADB Mode
ADB mode is a method of unlocking Huawei devices that are turned on and have USB debugging and root enabled. To unlock Huawei via ADB mode using Sigma Key, follow these steps:
Select "Qualcomm" platform from the tab menu in the upper left side of the software.
Go to the "Unlock" bookmark.
Connect the phone to PC using USB cable.
Press "Direct Unlock" button.
Wait for the process to complete.
Note: This method works for most Huawei models, except for S7-301u, S7-302u, S7-303u, S7-312u and S7-721u. For these models, use the direct unlock option in the "Service" bookmark.
Unlock Huawei via Software Testpoint Mode
Software testpoint mode is a method of unlocking Huawei devices that are turned off and do not require disassembling the phone or connecting hardware testpoint to it. To unlock Huawei via software testpoint mode using Sigma Key, follow these steps:
Select "HiSilicon" platform from the tab menu in the upper left side of the software.
Go to the "Service" bookmark.
Connect the phone to PC using USB cable in Upgrade mode:
For Android 10: Press and hold VOL+ and Power ON buttons. Select "Upgrade mode -> USB upgrade" from the menu that will appear.
For Android 9 and lower: Press VOL+ and VOL- and connect USB cable.
Press "Software Testpoint ON.../OFF" button.
Select original update.app flash file in the menu that will appear (main file). It must exactly match the smartphones firmware version. You may take it from update_sd_base firmware folder or use original FullOtaUpdate file from [this website]. Use SD_update file type for the latest Android versions (Android 10.0.1, Android 10.1 and higher). Use the same or higher firmware version.
The device should now enter "Factory mode - HUAWEI USB COM 1.0". Now you are free to run different service operations, like Remove FRP or Huawei ID, Read/Write operations, etc.
If you used a different firmware version for software testpoint operation, perform Enable Downgrade in the Service tab as the first operation right after software testpoint. It is necessary for correct flashing of the device via Update mode in future.
To exit software testpoint mode, press "Software Testpoint ON.../OFF" button again and select original update.app flash file in the menu that will appear (main file). The device should now reboot normally.
