Did you try the HDMI extender? If you're in the US you can request one at https://my.roku.com/HDMI (other countries may work, but I wouldn't count on it) or just save yourself the trouble and get one for a few bucks online.

so the stick was overheating but the onscreen message always only said low battery. i've tried plugging into a different outlet, using a different power adapter, a different HDMI port, using the supplied HDMI extension cable, even running a fan, nothing works now. in the past, before even resorting to using the HDMI extension, i would still be able to use the streaming apps for 15 -20 minutes after enough cooling downtime before the warning pops up again, but now, it immediately displays the low battery warning on boot rendering the stick unusable. what should i do? please advise. thank you.

Restart your Roku device: Restart the device from the settings menu. Go to Settings > System > System restart > Restart.
Re-install the channel: After your Roku device restarts, visit the Roku Channel Store and add the channel again.
