Factory Reset / "Unbricking"
In the extreme case that a LAN Turtle has become permenantly inaccessible or inoperative, there is a quick method for recovery using a special web interface.
Download the latest factory image from https://downloads.lanturtle.com/turtle-2-factory.bin
Carefully open the LAN Turtle case by removing the two screws underneath the sticker on the bottom
While holding the button on the bottom of the LAN Turtle, plug the device into a computer
After 3 seconds let go of the button and wait an additional 30 seconds to receive an IP address from the LAN Turtle
If you do not receive an IP address in the 192.168.x range from the LAN Turtle within a minute, statically assign the LAN Turtle's interface to 192.168.1.2 (netmask 255.255.255.0)
Browse to the LAN Turtle firmware recovery web interface at http://192.168.1.1
Follow the on screen prompts to upload and flash the factory image downloaded in step 1
When the flash is complete the LAN Turtle will reboot and will be accessible again from 172.16.84.1 with the default username root and password sh3llz
