I had this same issue although using a 2.4a usb power source instead which should have been enough and did notice that sometimes it won’t bootloop and sometimes it bootloops
Hello @CaptainAlbert
Thanks for reaching out here in the Community.
Could you tell us how are you powering your Roku device? Is it connected to the USB port of the TV or to a wall outlet? In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.
Using the included power cord and power adapter, we suggest plugging your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV.
Let us know if there's any difference after.
Regards,
Karla
