How do you update Raspberry PI Firmware from Lakka command line (ssh)

i want to update my rpi4 firmware to a newer version, but my only Os is Lakka, i tried a few things i’d googled in the ssh command line but none seemed to work. does anyone know the commands etc for updating it. thanks in advance

Please don’t ask the same question in multiple topics. I answered you on the other one.

So, I can’t find the other post anywhere but have the same question. Any help?

Short answer: you don’t since everything is embedded in Lakka

Long answer: what do you mean by “firmware”?

I know there was some firmware that reduced temperatures and power draw and the pi foundation released it a while back. So, whatever they meant by firmware at that point. That’s all baked in?
