We did this and it did not make any difference.
We started out with around 40+ channels. I deleted all of them so that we're down to Amazon, Hulu, Netflix, and YouTube, and Pandora and now are able to use all of these again. But obviously, that last update uploaded a massive screen background image that (seems) to have taken up a huge amount of memory on the Roku. I know we have an older version of Roku (version 3) but the updates and uploaded images would appear to be consuming more memory than it can handle until it finally reaches a point where it can no longer work. The SD card doesn't supply enough memory to put a dent in its operating capacity.
So my follow up query would be is there any way to delete these seemingly enormous background images from the Roku and just have 1 background/theme?
I could not find any way to do this on the settings.
Also, is there any way to boost the memory capability of the v.3 Roku than just the SD card? For example, could I retrofit it somehow with a 1T flash drive or something like that so it can have enough memory capacity to handle more channels again? I know some channels are certainly bigger than many others but I'm trying to diagnose why it worked fine one night, then the next morning the forced update and new background image appears to have crashed it and caused it to have used up 90% of its memory. Just trying to figure out what's going on with it.
Thanks for the reply. I'll read over it a few times to make sure I'm absorbing what you're describing. I think I get the gist of it, but I don't think it explains how the glitch or bug happened or could have happened.
