My experience going from 334 to 336 on my Hopper 3: Based on what I read here, I decided to force upgrade to 336. With 334 currently installed, I choose the upgrade option in Tools and even though it doesn't tell you anything, it took some time and started a reboot so I assumed it found an update. When it came back up, my version still said 334. So I thought they may have pulled 336 and rebooted my hopper for fun! Well, even though it appears to do nothing, all of a sudden NONE of my Joeys (three Joey 2.0's and four 4K Joeys) stopped working. Said they couldn't find the Hopper, yet it showed connected strong but unlinked. I was on the phone for a while with a tech and they made me redo everything I had already done several time (reboot both, check wiring, etc..). When she gave up and wanted to schedule a tech visit to check wiring that I know was good, I asked and received escalation to a higher tech level. He said I should have made sure my Joeys were in standby mode prior to the forced update so I went and put them all in standby (hit the power button on them to put them to sleep). He said they should update the next time the hopper checks their software version and notices that they are out of sync (the true problem). Next morning, I was good to go and my Hopper now said it is on 336. So I guess my recommended process for upgrading is (and read completerly because you may not want to!), 1. Put all Joeys in standby mode, 2. Force update the Hopper, 3. Go to bed, 4. Wake up to working receivers AND external drives, but now with THE DREADED HDCP ERROR TRYING TO WATCH HBO! So choose wisely. For me it appears I could either not have upgraded and have my premiums and no external drives, or upgrade and have external drives and no premiums until the next software fix. ARGHHHH!!!! Dish has been driving me nuts for the past year. P.S. Still no NetFlix on 4K Joeys. It's been a YEAR!!!
