Upgraded to 2.7.0 earlier today with no issue. Found that there was a 2.7.1 upgrade that had some IR enhancements and wanted to take advantage of it, so attempted to perform that update about an hour later. Errored out during the upgrade w/ an "Invalid Length" error and after a few consecutive attempts, just rebooted my PC and tried again. This time, when launching the browser, received a Java error in the browser when clicking "Administration Console". Error is reproduced below:

I *can* connect to the device and launch the admin console using the http://www.universal-devices.com/99i/ link, but still continue to get invalid length errors when attempting to flash the 2.7.1 (or 2.7.2) upgrade. I have a backup from pre-2.7.0-upgrade, but even attempting to reload that (which succeeds) still gives me the same error as above when trying to launch the Admin console from my "local" URL.

 

Do i have to perform a factory reset and re-flash the upgrades?

Isn't this just a local PC issue and shouldn't launching the Java console thru the alternative URL re-populate the cache on my PC with the appropriate applpet information?

Any thoughts as to why i'm having such a problem with upgrading the firmware all of a sudden?

 

I'm really jazzed to get my Harmony One working w/ the 99i ... of course now I'm *stuck* ... ain't that just the way of it...

 

Any help would be greatly appreciated.

 

Thanks -

 

Dave

Hello Dave,

 

Apologies for the inconvenience. Please do NOT factory reset your ISY. What you want to do is:

1. Clear your Java Cache

2. Make sure your firewall software is off

3. Go to http://www.universal-devices.com/99i and try the upgrade again

 

If this fails - and if you have a remote URL which allows us to login to your ISY - please provide it to support@universal-devices.com along with your credentials (reset to admin/admin please) and we'll try to upgrade it remotely.

 

With kind regards,

Michel

Michel-

Tried clearing the cache, even tried my remote access from my office and got the same Java error on a completely different PC this morning. I'll resett admin this evening and will email support.

 

thanks.

Hey Dave -

 

After clearing your cache and disabling your firewall software, have you tried loading the latest firmware using this URL?

http://www.universal-devices.com/99i

 

Please re-download a fresh copy of the firmware to install.

 

Until the issue is resolved, you won't be able to access the Admin Console from a remote location - you will have to access from a local PC using the URL listed above.

I was able to login to the admin console using the

http://www.universal-devices.com/99i interface, but still can't load the firmware - "invalid length" error...

Assuming you've tried after clearing your cache, disabling your firewall, and re-downloading a fresh copy of the firmware, then please submit a support ticket here for someone to assist:

 

http://www.universal-devices.com/supp_contact.htm

Cache cleared, a/v disabled, still can't get my device to upgrade past 2.7.0 either using my local URL or the http://www.universal-devices.com/99i/ link. Also still get the Java error when attempting to access the Administration Console via my URL, both on the LAN as well as remotely from my office.

 

I've opened a support ticket as requested and will wait for further instructions.

 

thanks.

I've encountered the same Java exception as the original poster (Exception: java.lang.ClassNotFoundException: com.universaldevices.client.ui.UDClientApplet.class) in very similar circumstances.

 

In my cases I did a successful upgrade to 2.7.0 from 2.6.13, took a backup then tried to upgrade to 2.7.6 (with AV disabled and no Windows firewall, just as with the prior upgrade). I encountered the "Invalid Length" error. Trying to access the Admin console then gives the Java exception.

 

My case then differs from the OP. If I use the http://www.universal-devices.com/99i link, a Java console is displayed but no devices, and no ability to retry the upgrade. I've tried clearing the cache. This is on Vista + Firefox.

 

So now I'm a little stuck and wondering how best to proceed?!

 

Thanks,

 

- Andrew

Never mind. Just found your JNLP utility (http://www.universal-devices.com/99i/2.7.6/admin.jnlp) which allowed me to enter the address of my isy99, and then the console started ok. The upgrade to 2.7.6 also worked OK this time

Hi andrewm,

 

Thanks so very much for the update and apologies for not having gotten back to you sooner.

 

With kind regards,

Michel
