I failed via usb key as well as ilive editor.
T-112 and idr-48
I solved it this way anyhow:
you need the usb stick AND the editor
-
unzip the firmware zip
-
copy the unzipped folder to your usb drive in the root dir.
-
copy the folder in the unzipped folder also to the root dir.
-
boot everything and connect the usb to the T-112
-
go to update firmware - it detects the firmware and everything is checked green
-
do the update
-
it will break down now but first it did update the touchscreen.
-
shutdown everything
-
boot the idr-48 only
-
log on with the editor
-
update the idr-48 as described in the allen&heath update manual
-
idr48 was successfully updated
-
keep the idr running and switch on the t-112
-
now repeat the first steps with only the surface left to be updated. this will work too.
-
now you’re done
-
load your show and enjoy V.1.9
I have been unable to update my T112 and iDR48 to v1.9 and I can’t get the US distributor to return any calls. I’ve contacted Full Compass where I purchased my setup and my rep there has been unable to get a response either.
American Music and Sound is where everything in the US is supposed to be directed, and I’m getting very frustrated that I’ve now been trying to update my console since 2012 and I’m no farther along in the process.
Do I have any options other than American Music and Sound to get this taken care of?
Hi,
Same problem for me, I don’t know what happen. I don’t try to downgrade today, but i will make it tomorow.
For the moment, I have no connection to the surface and no connection to the rack.
Hope we could have a reply for this problem! 
Best Regards,

Hi
My problem with the update, v.1.9 via usb, was that the surface connection completely disappeared. Could not access the console in any way, not even when I entered the surface IP address, so I downgraded to v.1.83 again.
After the downgrade, I reboot and now it works as before.
I have tried to update several times but contact with the console disappears even though it is listed as OK for the update.
Any suggestions?
