Hi, your sangfor device is pingable from the managemetn network?
If not, to perfrom a reset, you can follow these steps:

Reset with USB/Flash Drive:
Create an empty text file named reset-password.txt in the root directory of a USB drive.
Insert the USB drive into either of the USB ports of the NGAF at the front side where the ethernet ports are, and then restart your NGAF.
When the NGAF can normally log on to the Web User Interface, remove the USB Drive.
Check the results in the reset-password.txt file on the USB drive. If the recovery is successful, the restored password will be recorded in this file.
Reset with Cross Cable:
Use the power button to shut down the NGAF device.
Prepare a cross cable.
Use the cross cable to connect any two interfaces of the NGAF device (Note: The two interfaces can’t be bypass interfaces).
Start up the NGAF device and wait for 5 minutes.

Resetting a Sangfor NGAF with corrupted firmware requires a two-pronged approach:

    Hardware Reset (Optional): This can be helpful if the corruption prevents the NGAF from booting normally.
    Firmware Recovery: This is the essential step to restore the NGAF firmware to a functional state.

Hardware Reset (Optional):

This step is only necessary if the NGAF won't boot up due to the corruption.

Important: Performing a hardware reset will erase all configuration settings on your NGAF.

Here are two ways to perform a hardware reset depending on your model:

Method 1: Using a Reset Button (if available):

    Locate the reset button on your NGAF device. It's usually a small button recessed into the chassis.
    Use a pointed object (like a pen) to press and hold the button for a few seconds (refer to your NGAF manual for the exact time).
    The NGAF will reboot with factory default settings.

Method 2: Using Console Port (if no reset button):

    Connect a serial cable to the console port on your NGAF device and a serial port on your computer.
    Open a terminal emulator program on your computer (e.g., Putty, HyperTerminal).
    Configure the terminal emulator to match the NGAF console settings (usually 9600 baud, 8N1).
    Power on the NGAF device and observe the console output.
    Look for any prompts during the boot process indicating a hardware reset option. (Consult your NGAF manual for specific instructions as these prompts may vary)
    Follow the on-screen instructions to perform a hardware reset if available.

Firmware Recovery:

Here's how to recover the firmware on your Sangfor NGAF:

    Download the Firmware: Download the latest compatible firmware version for your specific Sangfor NGAF model from the Sangfor website or a trusted source.
    Prepare TFTP Server: Set up a TFTP server on your computer or network where the downloaded firmware file is accessible.
    Connect to NGAF Console (if needed): Connect to the NGAF console using a serial cable and terminal emulator program (as described in the optional hardware reset section).
    Boot into Recovery Mode: During the boot process, some NGAF models might offer a "Boot from TFTP" option. (Consult your NGAF manual for specific instructions as these methods might vary)

    If such an option isn't available, hardware reset might be necessary as a last resort after backing up any critical configuration data (if possible).

    Provide TFTP Server Details: If prompted in recovery mode, provide the IP address of your TFTP server where the downloaded firmware is located.
    Firmware Upgrade: The NGAF will initiate the firmware download and upgrade process. This might take some time.
    Monitor Console Output: Monitor the console output for any errors or completion messages during the upgrade process.
    Reboot: Once the firmware upgrade is complete, the NGAF should automatically reboot with the recovered firmware.

Resetting your Sangfor NGAF (Next-Generation Application Firewall) when its firmware is corrupted typically involves a process that restores the device to its factory settings. Here’s a detailed step-by-step approach:

1. Prepare for Reset: Ensure you have access to the NGAF appliance and necessary credentials (administrator access). Backup any critical configuration or data if possible.

2. Enter Recovery Mode: Most NGAF appliances have a recovery mode or a way to access a bootloader menu for recovery. This is usually initiated by connecting a console cable to the NGAF's serial port and accessing the console interface during boot-up. Consult the NGAF documentation or support resources for specific instructions on entering recovery mode.

3. Reinstall Firmware: Once in recovery mode, you will need to reinstall the firmware. Prepare a copy of the NGAF firmware image file that is compatible with your appliance model. This file is typically obtained from Sangfor's support website or customer portal.

4. Upload Firmware: Follow the prompts in the recovery interface to upload and install the firmware image file onto the NGAF appliance. This process may involve using a TFTP (Trivial File Transfer Protocol) server or similar method to transfer the firmware image to the NGAF.

5. Complete Installation: Allow the firmware installation process to complete. This may take several minutes as the NGAF appliance updates its operating system and configuration to the factory default settings.

6. Configuration: Once the firmware installation is successful, the NGAF appliance will reboot. You will need to reconfigure the NGAF with basic network settings and any specific configurations required for your environment. Use the default or previously backed-up configurations as a reference.

7. Testing: Verify the NGAF functionality by testing its connectivity and functionality in your network environment. Ensure that all necessary policies and configurations are restored or reconfigured as needed.

To reset the NGAF (Next-Generation Advanced Firewall) firmware when it's corrupted, you'll need to use the Emergency Recovery Mode. Power cycle the NGAF device and immediately press and hold the "Reset" button for 10 seconds while booting up. Release the button when the LED lights start blinking. This will enter the Emergency Recovery Mode. Use a serial console or SSH connection to access the device and execute the command `reset` to restore the factory settings.

if the firmware is corrupted then only option is to reset it to factory default with a pen drive and a valid FW version.

Hello, do you mean that these virtual machines—whose password-protected virtual bios settings—are HP appliances? If so, a lot of virtual hardware will change when they migrate to HCI (even the virtual bios is different). Before going to an HCI, I advise you to clone one of these virtual machines on your ESXI environment and try removing the virtual bios lock.
