Splathappy Posted June 30, 2017 Report Share Posted June 30, 2017 I 'm attempting to upgrade the firmware in my 156-B10 . I have tried several different USB sticks. Some sticks showing power connection but the unit does not seem to recognize the connection, when I attempt a "Safely remove DOK" I get a "DOK remove failed" message with . Any Ideas?

MVP 2021 Joe Tauser Posted July 7, 2017 MVP 2021 Report Share Posted July 7, 2017 Make sure your stick is big enough. At least 8 GB. Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted July 11, 2017 MVP 2021 Report Share Posted July 11, 2017 There's nothing worse than a stick that's not big enough! cheers, Aus Quote Link to comment Share on other sites More sharing options...
sgull Posted July 17, 2017 Report Share Posted July 17, 2017 Hi Aus I have always been led to believe that size doesn't matter. Always something new to be learnt on these forums. Regards Denis Quote Link to comment Share on other sites More sharing options...
UNICO2 Posted August 3, 2017 Report Share Posted August 3, 2017 As I recall, I ran into this problem and it turned out to be that in Unilogic Password Management a bunch of stuff was password protected (like UniApps Adminstrator but not UniApps Guest) and if you put in the wrong password for UniApps Adminstrator you were logged in as a guest (with no indication that you had entered the wrong password) and also with no privileges so that the USB DOK wasn't even seen when you tried to upgrade etc...

DanT Posted August 8, 2017 Report Share Posted August 8, 2017 The Minimum USB DOK is 4 GB for Upgrades. Anything less will cause the UniStream to Brick - I have seen one do this - It had to be replaced. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted August 9, 2017 MVP 2021 Report Share Posted August 9, 2017 I bricked one myself when the UniStream first came out - I was using a 2 GB stick. Now I use 16 GB - they're fairly cheap. Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted August 10, 2017 MVP 2021 Report Share Posted August 10, 2017 So you guys are saying that the units were completely bricked? No way possible to get them back? It seems a bit astounding to me that a lower level recovery facility isn't available when 2 of our very experienced members have had such an easily done error. Something for the creators to look at? cheers, Aus 1 Quote Link to comment Share on other sites More sharing options...
