Respuesta de Huawei a la solicitud del código:
Dear Customer,
Thank you for contacting Huawei device.
Sorry that there have no bootloader unlock code for ALE-L21 items.
By default , you can do fastboot downloading for some images directly without Unlocking bootloader..
We suggest you'd better not root your device which would avoid the warranty and maybe cause it freeze.
Once again thank you for contacting Huawei device.
Best Regards.
Huawei Device Customer Care Team
