Secure Remote User Device Unlock
First Claim
1. One or more computer-readable media storing computer-executable instructions that upon execution cause one or more processors to perform acts comprising:
- receiving a carrier unlock request for a user device;
determining one or more verifications to be performed based at least on a unlock scenario requested by the carrier unlock request for the user device;
performing the one or more verifications to determine whether the user device is eligible for a carrier unlock; and
sending a unlock command to the user device in response to determining that the user device is eligible for the carrier unlock, the unlock command to disable a comparison of a device carrier code of the user device to a subscriber identity module (SIM) carrier code stored in a SIM card of the user device.

Abstract
A device unlock application on a user device may interact with a server to automatically carrier unlock the user device. The server may receive a carrier unlock request for a user device. The server may determine one or more verifications to be performed based at least on a unlock scenario requested by the carrier unlock request. The server may perform the one or more verifications to determine whether the user device is eligible for a carrier unlock. The server may send a unlock command to the user device in response to determining that the user device is eligible for the carrier unlock. The unlock command may disable a comparison of a device carrier code of the user device to a subscriber identity module (SIM) carrier code stored in a SIM card of the user device.

10. A computer-implemented method, comprising:
-
receiving a carrier unlock registration request from a device unlock application on a user device at a server, the unlock request including at least an encrypted device key of the user device that is integrity protected by a trusted key of a trusted environment of the user device; and decrypting, at the server, the encrypted device key into a decrypted device key in response to a validation of the trusted key by a trusted third-party authority as belonging to the user device; receiving, at the server, a carrier unlock request for the user device that is integrity protected by the device key; validating, at the server, the carrier unlock request that is integrity protected by the device key using the decrypted device key; and determining, at the server, whether to fulfill the carrier unlock request following a validation of the carrier unlock request via the decrypted device key. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A server, comprising:
-
one or more processors; and memory having instructions stored therein, the instructions, when executed by the one or more processors, cause the one or more processors to perform acts comprising; receiving a carrier unlock request for a user device that is initiated by a device unlock application on the user device; determining one or more verifications to be performed based at least on whether a permanent carrier unlock or a temporary carrier unlock is requested by the carrier unlock request for the user device; performing the one or more verifications to determine whether the user device is eligible for a carrier unlock; and sending a unlock command to the user device in response to determining that the user device is eligible for the carrier unlock, the unlock command to disable a comparison of a device carrier code of the user device to a subscriber identity module (SIM) carrier code stored in a SIM card of the user device. - View Dependent Claims (18, 19, 20)
