Factory Reset
In the extreme case that the Key Croc has become permanently inaccessible or inoperative, there is a quick method for recovery using a special boot pattern.
If protect arming mode is enabled, you must first disable this feature by removing the corresponding lines in config.txt and restarting the device before attempting a factory reset, otherwise the arming mode may become permanently locked.
Hold the arming mode button with a paperclip, SIM card tool or similar instrument.
- While holding the arming mode button, plug the Key Croc into a USB port and unplug it immediately after the green LED turns white.
- Repeat step #2 three times while holding the arming mode button.
- Finally, plug the Key Croc into a USB port a 4th time when when the green LED turns to an alternating red/blue pattern, release the arming mode button.
- This process will take 5-10 minutes. When the firmware recovery has completed, the Key Croc will reboot, indicated by the green LED.
Technical note: This process will replace the primary boot partition with a copy of firmware version 1.0 kept on a backup partition. If the backup partition has been damaged, this process will fail.
