Roku4 microSD reboot loop revisited

Bought 3 roku4's within a couple months of original release 4 years ago, one was replaced after cleaning misapp 2 years back;  units were eventually upgraded with 32GB microsd cards and ran fine for well over a year after.  After firmware 9.2 was pushed out, units began failing one after the other some 2-3 months later, only fix was removal of the microsd cards.  Roku advised replacement of microsd card(s) with 2GB 'confirmed' good cards they sold.  Fyi, 32GB cards removed were tested and found to be defective.  Roku 2GB cards were ordered for all units and have been operating without problems for ~1 year until today, now I'm starting to get defective cards once again.  I do own an ultra 4640 unit that has had no problems (no memory upgrade and doesn't complain with the same number of apps as the roku4's) so I'm coming to the conclusion that either roku4's 'eat' microsd cards or firmware updates are involved.  None of my units has recieved 9.3 upgrade as of yet, although it was announced quite a while back.  

I will keep my eye on 'Sale' specials on newest ultras or take the plunge to fire boxes as roku seems to be getting wobbly.

Re: Roku4 microSD reboot loop revisited

The need for the SD card isn't really all that critical. It is only used for channel storage, and only if you have a large amount of channels installed. The Roku keeps the most used channels in storage, and if you don't have the SD card it might have to reload the unused channel again if it's requested. Unless you are always using a large number of channels, it's unlikely you'd even experience that reload very often. I've never used an SD card in any of my devices that had the slot. At worse it adds a bit of extra time to load an occasional channel. 

The Roku 4 has 512 MB of channel storage, which is the same as all current Roku devices. The Ultra 4640 was the only player that ever had more. As I said, unless you have many, many channels, and constantly use a large number of them, having an SD card will likely never make a difference in actual use.

Re: Roku4 microSD reboot loop revisited - same with Roku 4670 (brand new)

I bought 2 of the Roku 4670's in July from Best Buy.  One unit keeps flipping out.  It either goes on 10 minute endless reboots or it takes forever to come up after doing a restart.  I know it's the MicroSD card.  Remove the card... and it works fine.  However... none of the channels remember their logins.  So it sucks.

I've tried all kinds of other cards from 2 gigs to 64 gigs.  I even used previous ones from the ROKU 4 Ultras that these new roku's were replacing. 

Life is good for a week or two and then it hits again.  change the card, and all is good.

I too had this issue back on the Roku3.  I can't believe this many generations of new Roku's and it's still a problem.  

Ongoing reformatting... and resetting up channels.  ugh.

I had my SD card act up. I removed it and the Roku4 booted up fine. I tried putting it back in, and it would freeze at 'loading card'. I removed it and put it in a Windows computer. It obviously cannot read the Linux format, so it asked to reformat it, which I said OK. I then put it back in the Roku, which immediately asked to reformat. So far, it's been OK.

Well, the latest/newest ultra, according to a couple of the early reviews, no longer has a microsd memory slot.  So I guess they solved the problem, it seems they increased the internal memory (8GB?) So how many channels it can hold is unknown, the space needed varies wildly.  The amount of time/bits needed to reload is fairly minimal, I guess they figured that most folks have a decent enough connection, even if over wifi, it takes <10sec to reload, at least that's what I get on my slowest 2.4ghz link.  

I'll hold on to what i have, unless and until if roku ever does what they announced over two years ago, a unified streaming guide (which several of its competitors have to varying degrees of usefulness).  Even though I have a fair piece of change rolled up in these units, firetv is looking better every day if I can figure a way to cut loose the $800 or so to switch over.

Re: Roku4 microSD reboot loop revisited - same with Roku 4670 (brand new)

I've never found the need for an SD card, but then I typically only use perhaps a dozen at most channels. My players have all had sufficient channel storage to keep my main use channels in memory. On a rare occasion I've seen a channel have to reload, but it's just not often enough that I ever felt the card was necessary.

And there are still a few people that feel the SD card somehow improves the Roku performance. Other than not needing to reload an off-loaded channel, the SD card has no impact on Roku performance. So unless you regularly use many different channels, the SD card really doesn't do anything.

Roku has added the 4800 to the developer's hardware spec page, but they don't list the channel storage memory on that chart. It does have 2 GB of operational memory, but that's the same amount as the 4670. Early tests are showing the 4800 is about 12-15% faster overall compared to the 4670, all due I'm sure to the new CPU hardware. So compared to even older Roku devices, the new Ultra should be noticeably faster overall.
