My guess is MOST of us are still on the FW that doesn’t fix it since ROKU is not pushing it out that quickly or making it available for manual download.
just tried the update to v8 build 4128-28 via the normal update check screen and still has the 1080/720 bug.
Resolution resets to 1080 after restart and still have to do the blind menu up/up/down/down/L/R/L/R/B/A/Start trick to get the res back to 720.
model: 3710X - Roku Express+
V. 8.0.0 | build 4128-28
worked perfectly fine with whatever the last 7.x version of the driver was. Would be nice to be able to switch back to that until the current version works the bugs out, not sure why that's not an option. Forced upgrade with no downgrade option seems like a bad idea... :\
