Thanks for the post.

I have passed along your concerns to the appropriate Roku team to investigate further.

Thanks,

My son's tv did the same thing. It got stuck during the update process. The two of us have spent hours trying every possible combination of resetting the router, factory reset of tv, shutting off the tv, etc. Eventually the remote quit working. We ordered a new remote. The tv is still doing the same thing. Add in the frustration of trying to download an update via computer and the Roku model number can only be accessed from the tv that is stuck in reboot mode. This is absolutely ridiculous for a tv that is not even two years old!

Mines doing the same thing after it updated tonight and it’s annoying. Can we revert back the update???

On my TCL 65R625 it downloaded 11.5.0 4235-88 and it went into a loop, it would reset every 15 seconds after loading the home screen. I tried everything I could and called TCL support but to no avail. I read that I may need another main board so I ordered one from EBay ($32), installed and voila back working again. The new board come with SW version 9.1.0 1516-88. I had to factory reset the new board because it was in store mode and had a Canadian support URL. I decided to order a Roku 4K stick and not hook up the TV to the internet and it worked fine all night and day until curiosity got the best of me and I hooked it up to the internet. I should have trusted myself and not did that, it downloaded the SW 11.5.0 4235-88, restarted and then went back into loop mode like before. I tried mostly everything including Roku support which was a JOKE. My old board never went into recovery mode but this one did so I went on the SW site, used the Roku model A108X and the device serial number. I put the TV in recovery mode, put the USB in and it downloaded the SW then said download failed. I tried this a couple of times, reformatted the USB and redownloaded the SW. I finally tried the DEVICE ID instead of the SERIAL number, downloaded the SW, put TV in recovery mode, put in USB and it downloaded to 100% and then restarted and it stayed on. The SW version that worked was 11.0.0 4193-88, I DID NOT hook it back to the internet, I'm just using the Roku stick. On another note my batteries were draining in my remote every few days several months ago, I read to factory reset the TV so I did and when it came back on the remote and WiFi quit working, the TV didn't find any networks, even hotspot networks. The wifi was not resolved with the new board and I had to program a DirecTV remote to use until I got another remote, I also used the app. The DirecTV remote doesn't have a options function or RW, FF, PLAY, PAUSE OR STOP.
