Cisco IP phone customization help

I just started a cool job with a Cisco IP phone that has a rad LCD display. That phone appears to be this model:
(edit: corrected model URL)
https://www.cisco.com/c/en/us/products/collaboration-endpoints/ip-phone-8841/index.html
What I really want to do is use my own customer wallpapers for this phone. I've gotten pretty far in figuring things out, but I'm still missing something or other. What I've done so far:
- Created 800X480 images in 24 colors
- created thumbnail images for those wallpapers
- downloaded list.xml from the tftp server
- Edited list.xml to include references to my new wallpapers
Here's the part where I'm stuck: I can't seem to figure out how to upload my files. I know the correct upload directory is Desktops/800x480x24/ because that's where I got the list.xml file from.
I've tried this syntax on cmd.exe:
tftp [tftp server address] put masseffect.png Desktops/800x480x24/
I also tried:
tftp [tftp server address] put masseffect.png /Desktops/800x480x24/
Neither worked. There is also a second tftp server address that I tried with both syntax types and neither worked.
Is this just a case where I don't have access to that directory and so can't upload? I could probably just ask IT to upload it for me, but I'd really love to be able to figure this out. I don't have access to Cisco call manager/utility and I don't have access to download it from our available software. Am I just outta luck here?

Error on server: Illegal TFTP operation
Connect request failed
I'm reading a doc on how to 'hack' my phone and it's saying I basically have to run a tftp server from my computer to do what I want to do. Which I don't mind except I don't have a static IP on my laptop.
My googling suggests that you'd need access to the TFTP server that serves those phones currently to do it.
And this error is suggesting I don't have write access?
Yeah sounds like a permission issue, TFTP is a pretty dumb protocol in general.
Try something like this, maybe it is having issue with assumed ASCII transfer:
Here's the wallpaper screen while running the phone on my TFTP:
I believe this is the error it gives when trying to select one of the default wallpapers (just guessing since I can't see thumbnails)
While this seems to be the error it gives for my custom wallpapers:
Side note is that though the other wallpapers are .png format, I can't view them in any image program I have:
I will figure this out if it kills me.
Edit: I looked at the actual model of my phone and it's this one: https://www.cisco.com/c/en/us/products/collaboration-endpoints/ip-phone-8841/index.html
Does anyone know what program creates List.xml.sgn? Can I edit that file in a text editor?
Edit: from what I've been able to figure out, everything I'm trying to get working hinges on List.xml.sgn, and I don't seem to have a way to edit that file.
Security is not active on this phone.
I think the presence of the .sgn files was a mistake on my part, so I used the same process I used the first time to get a list of what files the phone needs, downloaded them from the original tftp location, and as I suspected the first time around at least those files are not present.
Unfortunately, I still can't get the phone to load the images I created:
Not the loading circle in the upper right hand corner - it's continuing to spin without appearing to actually load anything.
It's clear from my tftp server that the phone is at least accessing the correct file:
I'm wondering if the XMLDefault file needs to be edited to make this work? I do see references to the old tftp IP address in here... I'll try editing it and give it another go.
