I just unbricked mine following these instructions. Mine was in bootloop that wouldn’t go past the wink relay loading text.

- While your relay is LOOPING, cover up the Proximity Sensor and press the Top Switch Button.
- Doing so should bring you to Recovery Mode
- Wipe the Cache 3 Times
- Delete and Reset Device 3 Times
- Reboot device
- Your Putty screen will start printing a bunch of gibberish.
- Have the following copied to your clipboard : am start -n com.android.launcher/com.android.launcher2.Launcher
- While your Putty is updating - keep pasting what is in line 7, and keep pressing Enter on your keyboard.
- Hopefully, you will get lucky - and the Launch Screen will appear.
From here i used these instructions to push and install the soft buttons and apkpure
This allowed me to install Nova and once rebooted I could go straight into android and not wink.
NOTE: I don’t know if I actually needed to run that command through terminal or if I could have cleared the cache 3 times and ran delete and reset device 3 times to get the wink to finally load. It couldn’t get it to do anything until I did the the cache and reset 3 times each in the order above.
