Resetting the password for a 7004T-LM-V3 (typically an AHB 4-channel H.264 DVR board) requires physical access to the device's motherboard to clear the system's flash memory. Standard soft-reset methods like removing the backup battery are often ineffective because credentials are stored in non-volatile memory. Standard Hardware Reset Method
For models with the V3 firmware, the most reliable recovery involves "shorting" specific pins on the internal motherboard:
Power Off: Disconnect all power and peripheral cables (HDMI, USB, etc.).
Open the Case: Use a screwdriver to remove the DVR's outer shell and locate the motherboard.
Locate the Jumper: Look for a set of three pins labeled JPW or similar (Reset Jumper) near the SATA connectors.
Bridge Pins 1 and 2: Use a small metal tool, such as a paperclip or tweezers, to touch both Pin 1 (GND) and Pin 2 (RESET) at the same time.
Power On: While holding the short, reconnect the power cable. Continue holding until you hear a single beep (usually after 5–7 seconds).
Reboot: Remove the shorting tool immediately after the beep and wait at least 30 seconds for the system to initialize. Alternative Recovery Options
If the physical jumper is not visible or accessible, you may try these secondary methods:
Default Credentials: Try logging in with the factory defaults. The username is typically admin, and the password is often blank (empty) or 123456.
Super Password Generators: Some generic H.264 DVRs using High Silicon chips can be unlocked using "Super Passwords" generated from the device's system date or serial number.
Technical Support: Contact the original vendor or manufacturer (such as Xiongmai Tech) for a temporary override code based on the device's on-screen serial number.
Resetting the password for a 7004T-LM-V3 DVR (often based on the XMeye or HiSilicon platform) can be accomplished through software tools, mobile apps, or physical motherboard manipulation. 1. Default Credentials 7004t-lm-v3 password reset
Before attempting a hard reset, try the factory default settings: Username: admin Password: (Leave blank) or admin 2. The XMeye QR Code Method (Recommended)
If your firmware is from July 2019 or later, you can generate a reset code using your smartphone.
Trigger the QR Code: At the login screen, enter an incorrect password five times. A small QR code icon should appear next to the password field.
Scan with App: Open the XMeye App (or Sannce Vision) on a phone connected to the same local network as the DVR.
Get Reset Code: Navigate to Menu > Find PWD > Scan the QR. The app will provide a 6-digit Reset Code.
Apply: Enter this code into the DVR login box to reset it to factory defaults. 3. Super Password Generator
For older units, the password is often tied to the system's internal date.
Note the Date: Record the exact date (Year/Month/Day) displayed on the DVR monitor.
Generate Code: Use a "Super Password" tool or an online DVR Password Generator to input your DVR's date.
Login: Use the generated 6-digit code as a one-time master password to access the system and reset your credentials. 4. Hard Reset (Physical Motherboard Method)
If software methods fail, you must physically bridge pins on the motherboard.
Open the Unit: Power off the DVR and remove the outer casing.
Locate JPW Jumper: Look for a 3-pin jumper block labeled JPW near the SATA connectors or CPU. Some industrial routers have a reset button :
Bridge Pins: Use a screwdriver or tweezers to bridge Pin 1 (GND) and Pin 2 (RESET).
Power On: Keep the pins bridged and plug in the power. Continue holding until you hear a beep (usually 5–10 seconds).
Reboot: Remove the bridge and let the system finish booting. The login should revert to admin with a blank password.

This method is the most reliable for clearing all settings, including a lost administrator password. Power Down
: Disconnect the power adapter from the DVR board completely. Locate Reset Button
: Find the small, dedicated reset button on the PCB. It is usually located near the power connector or the edges of the board. Press and Hold
: Use a paperclip or a similar tool to press and hold the reset button firmly.
: While still holding the button, reconnect the power adapter. Wait for Flash : Continue holding for about 5 to 10 seconds
until you see the system indicator lights flash in a specific pattern.
