Reading bootloader code... Invalid command

[mobilealex]

I was trying to unlock the bootloader for the Huawei MediaPad T3 10 tablet with DC Unlocker, but it has failed with "Invalid command" error.

The log in DC Unlocker:

Can you please help me?

Use HCU software which is made for mobiles/tablets: https://hcu-client.com/
Mention what security patch your unit runs, you should be able to see it in same place as android version in device's settings.

It's Android security patch 1 September 2018, will HCU work?
BTW, HCU doesn't work on a virtual machine, which is the only thing I have got with Microsoft Windows running. Any workaround?

[Valdemaras]

Yes, it should work with this security patch and yes HCU does support this phone and may use same account on it. DC-unlocker doesn't work on VM as well, hence now explains why you get such random error. Sadly you need native Windows computer to work with either software.
