[Fire TV Q&A, Help & Troubleshooting] MiklerGM:
Hello,

I have no signal from Fire TV Stick after unsuccessful lower-power-mode setup.

The last thing, that I saw from this stick was the progress bar "Optimizing system storage and applications... Insufficient USB power detected." on an old TV with DVI adaptor.

Then I've got a new TV, with proper HDMI. The ports are working (checked them with the laptop and nintendo switch)

- I did the amonet hack unbricking procedure, so I have the adb access.

- I did't create a backup of the firmware that was installed

- I've tried to flash via TWRP 5.2.7.1_rooted, lineage-12.1 and the stock update-kindle-full_tank-288.6.3.9_user_639566220

- Every partition (system, data, cache, dalvik) was wiped before flashing the firmware

In the adb logcat there are messages that HDMI state changed from plugged in to plugged out
