This knowledge also applies to tablets.

After touching the Erase data button, if the device is offline and a message is displayed indicating that the data of the phone will be erased once it is connected to the Internet, data is not yet erased. In this case, you can touch Cancel erase to cancel the erasure.

You need to verify the password of your HUAWEI ID to cancel the data erasure.

You won't be able to cancel the erasure once it has been completed.
