[LIST] System version history, SBF MD5SUMs, & Release Note URLs - Motorola Photon 4G

This list is kept here for historical purposes (although it would probably be better off in a wiki page). This post contains all the known versions of stock system software released for the Sprint Motorola Photon 4G, including both OTA and unreleased/leaked versions.
This list is sorted by the build number (old builds are towards the top, new builds toward the bottom). Please let me know if there are any errors in this list. You can either send me a PM or make a post.
I won't be keeping track of download links for these files. There's already plenty of other people on XDA providing mirrors of the SBFs for you to download, all you need to do is go into their topic and find a working link.

Anyone notice any of the changes for 198_7? I'm guessing it's for fixes people were reporting for 198_6. I think the main thing was battery life problems and wifi errors. I never really had any of these problems myself but I just put it on my phone so we'll see.
Edit:
When I was using Juice Defender Ultimate on the 198_6 with it managing wifi, the wifi wouldn't autoconnect unless I had it search manually. This problem seems to be gone for the MoPho with 198_7.

Great work, this has been needed for some time!

I fail to understand why we can't have links to the SBF files w/ this list.. and a link to RSD as well as drivers (32 and 64 bit).. would be a handy place for someone to return to stock or flash a prior build if need be.
Since I'm not shy ... here is a link to a post where a member has posted links to mirrors of quite a few of the prior (and current) builds including RSD lite and drivers.

The reason why I'm not providing links to download the SBF and related tools is because I do not want to be held responsible for what anyone might (accidentally) do to their phone.
The list is for informational purposes only, and if someone wants to figure out how to flash back to stock, all they need to do is open Yay for Juggs' thread, or visit the "Roms" folder on his website.

Where can I download these files? j/k
I had too because you said NOT too!
Seriously though, thank you for this information. This is definately needed stuff. After a while, it does get confusing trying to keep track of all the different versions/updates especially when your MoPho doesn't play nice with one, and you need to go back to one it likes.
