ADT-1 Android TV
"Although the information we release has been verified and shown to work to the best our knowledge, we cant be held accountable for bricked devices or roots gone wrong."
This page will be dedicated to a general overview of descriptions and information related to the ADT-1 Android TV.
Purchase
The ADT-1 is not available for purchase and is only obtained through purchase from individuals who obtained a unit at Google IO or through the official "Request an ADT-1" page.
Tear Down
The ADT-1 Android TV is pretty easy to get apart once all the clips holding the case together are undone. In this tear down we used a razor blade but a guitar pick or similar small and durable piece of plastic is recommended.
Accessing Fastboot
- The bootloader on the ADT-1 distributed from Google IO comes unlocked. Below is the process on accessing fastboot interface.
Steps to enter recovery mode
- Hold reset button on back of ADT-1 for approximately 10 seconds or until device reboots.
- Screen will display fastboot options as seen in picture to the left. A short click of the reset button navigates while a long click selects.
Accessing Recovery
On the ADT-1 the standard "Android Recovery (3e)" is used. The menu for this mode is hidden behind Auto-Recovery functionality which clears the user-data and cache partitions.
Steps to enter recovery mode
- Through adb using "adb reboot recovery"
- Through the fastboot menu accessed with the process above.
- By holding the reset button for roughly 20 seconds.
