1.33.1 Upgrade not installing - No space left on device

I have downloaded PICED 4.14.2.206 and I'm trying to upgrade my Wiser2 from 1.31.463 to 1.33.1
I've used PICED to do it via the Wiser Transfer Utility, and tried the http://<ipaddress>/firmwareupgrade.html option.
Both say they have uploaded and installed correctly, but nothing has changed and it's still on the old 1.31.463 firmware.

I've waited the 15 minutes, I've rebooted the device, and still nothing.

Any ideas?

 

When using the firmwareupgrade.html route, Step 1 ("Uploading") stops at 37% for quite a while
and then I saw a quick flash of the screen with some sort of out of space error - so I assume this is the reason.
Is this a known issue? Is there a way around it?

 

I managed to grab the error - it is:

 

Do you need to upgrade the firmware in the Wizer at all. I know that some color touch screens are having problems with Piced version 4.14.2
Some things don't need to change, but if you need a newer version for new hardware keep the old one as well for legacy parts.

 

I'm wanting to upgrade to get rid of the old Flash requirement
And also I think it fixes an issue where you can't access via the ioS Wiser app over 3/4/5G
Currently it only works over Wifi

 

I've also tried putting the firmware on a USB key and renaming the file to wiser2firmware_upgrade.img and putting it in the front USB port - lots of flashing lights, but no upgrade...

 

I've got the exact same problem; did you find a solution for this? I've called tech support but no luck

 

I also have the same problem on 2 wisers. I have upgraded 14 now but had 2 where is sends the file and says wait 15 mins. But you still get the old login and flash player.
