Title pretty much says it all. Turned on my Roku and it said it had to update and it factory reseted the device. After getting the update, I tried to re-download all my channels but every time I tried to add one it said there wasn't enough space. It's a 3600X so it's a few years old, but it was working just fine before the update. I get that new sticks don't really break the bank, but am I out of luck?
Try another Factory Reset yourself: Settings/System/Advanced system settings/Factory Reset/<enter code>/Ok
If you still cant add channels (they actually should "Auto-Add" since apps are linked to the account, not the device), message @RokuDanny-R or @RokuKariza-D or @RokuMary-F with your account/device details (Device ID/Serial # from Settings/System/About) and a brief description of the problem and they may be able to help you further.
