Essential DC-Unlocker Commands List: The Top Guide for Modem & Phone Servicing

DC-Unlocker is a premier software tool used worldwide for unlocking, repairing, and servicing modems, routers, and mobile phones. While the client provides a user-friendly graphical interface, advanced users often use the built-in terminal to send direct AT commands to hardware for deeper diagnostics and manual control.

Below is a comprehensive list of the top DC-Unlocker commands for various servicing tasks. 1. Status & Diagnostic Commands

Before performing any unlock or repair, you must verify the device's current state. These commands help identify lock status and remaining attempts.

AT^CARDLOCK?: The most critical command for checking lock status. Result 1 means the modem is locked. Result 2 means the modem is unlocked.

The second value indicates the remaining unlock attempts (e.g., ^CARDLOCK: 1,10,0 means 10 attempts left). AT^DATALOCK?: Checks if the data lock is active. 0 = Disabled. 1 = Enabled.

ATI: Identification command that returns the device manufacturer, model, IMEI, and firmware version.

AT+CREG?: Checks the network registration status (useful for verifying if a device can see a carrier after unlocking). 2. Unlocking & Code Management Commands

These commands are used to manually input unlock codes or reset safety counters on specific Huawei and other compatible models.

AT^CARDUNLOCK="nck md5 hash": Used to manually enter the 8-digit Network Control Key (NCK) to unlock the device.

AT^WRTME=1,id,hash: A specific command used for newer Huawei models (like the E173 or E353) to reset the unlock attempt counter if it has reached zero.

AT^NVWREX=50502,0,128,...: Used to reset the Datalock to a default value like 00000000 or 12345678. 3. Connection & Mode Switching Commands

Sometimes a device needs to be forced into a specific mode (like "modem only" or "PC UI") for DC-Unlocker to detect it correctly. AT^U2DIAG=0: Sets the device to modem-only mode.

AT^U2DIAG=255: Sets the device to "Modem + CD-ROM + Card Reader" mode.

AT^SETPORT="A1,A2;1,2,3,7,A1,A2,4,5,6,A,B,D,E": A complex command used to reset port configurations to default. AT^CFUN=1: Restarts the modem or device. 4. Advanced Servicing Commands

These commands handle frequency band selection and hardware-level features.

AT^SYSCFGEX="00",3FFFFFFF,2,4,7fffffffffffffff: Sets the device to "Auto" mode for 3G/4G selection.

AT^SYSCFGEX="03",3FFFFFFF,2,4,40: Forces the device to a specific frequency (e.g., 2600 MHz).

AT^CVOICE: Enables or disables voice call capabilities on supported modems.

AT^HSDPA=1: Enables High-Speed Downlink Packet Access (HSDPA) for faster data. How to Use These Commands in DC-Unlocker
