Seeking Assistance: Need Original Firmware for CyberDog 2 Recovery After Custom Flash Attempt

I attempted to modify my CyberDog 2's firmware to enable GET request control functionality, but unfortunately this resulted in losing connectivity with the official mobile app. Here's my current situation:

• SSH access remains functional (credentials available upon request)

I would be extremely grateful if someone could help me with:

1. Guidance on where to obtain official CyberDog 2 firmware images for recovery
2. Advice on performing a complete system restore via SSH
3. Any alternative recovery methods that might be available

• I maintain full SSH root access to the device
• The system responds normally to basic Linux commands
• I'm happy to provide any additional system information or diagnostics that might be helpful

Thank you in advance for any assistance or pointers you can provide. I'm happy to test solutions or provide additional information as needed to resolve this situation.

No repository files, tests, or entry points are mentioned. Start by reviewing the CyberDog 2 device state through the available SSH access and locating official firmware or recovery documentation; done means restoring connectivity with the official mobile app without losing device access.
