[Moto X General] KidJoe:
This post/thread is to summarize where to find full SBF files, leaks, etc for the Moto X (2013 or First Generation).

REMEMBER... Always flash the same ROM/SBF or Newer to your phone. NEVER attempt to downgrade your rom!!! for more info, see DOWNGRADING

Motorola posts their complete STOCK "Recovery Images" (aka SBF files) for the GSM and Verizon Developer Edition X at -> https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images

If you have the Retail and/or Moto Maker XT1053 (aka Unlocked ships with T-Mobile SIM, or Unlocked Ships with Net10 SIM), you can also use the GSM Developer Edition (XT1053) roms from Moto's site.

If you have the Retail and/or Moto Maker Verizon X (XT1060), you can also use the Verizon Developer Edition (XT1060) roms from Moto's site.

There might be a delay in Moto making an SBF available.

For other models of X, I know of 3 sites for "leaks" which contain the SBF files for nearly every model of X (2013). You may need to check EACH site to find the particular rom you are looking for. NOTE: None of the following sites are owned, operated, or sponsored by Motorola. They may be down or offline at any time, without warning.

http://sbf.droid-developers.org/ <- DEAD when checking on 8/22/15

http://www.filefactory.com/folder/dd05c058d3ff8dbe/?sort=created&order=DESC&show=100&page=1 <- seems to have the most 4.4.4 roms

http://motofirmware.com/files/category/9-ghost/ <- DEAD when checking on 8/22/15 once there, look under the GHOST folder. (as of 11/9/2014, its format and access has changed)

http://motofirmware.center/files/ <- Select Moto X 1St Generation from the list along the right side of the page

Are there any others?

As 5.1 SBF files become available, they are being collected and curated in this thread -> [OFFICIAL] Collection Full Firmwares (FXZ/SBF) Lollipop 5.1

FAQ:

1. How do I know which file to download?

- If you are NOT running a 3rd Party or Custom ROM... take a look on your phone, under App Drawer -> Settings... Make note of what is listed under System Version, Android Version, and build number. Then visit one (or all) of the sites until you find the SBF that matches. The file name will usually contain parts or all of that info listed under settings, and possibly the carrier name, or acronym for the carrier name (Verizon might be VZW, Rogers Canada might be RCI, etc).

Normally I would suggest BEFORE you flash away from Stock, on the phone you first go App Drawer -> Settings -> About Phone... Make note of what is listed under System Version, Android Version, and build number. Then visit one (or all) of the sites until that host the leaked SBF files until you find the SBF that matches and down load the file to your PC for use later.. The file name will usually contain parts or all of that info listed under settings, and possibly the carrier name, or acronym for the carrier name (Verizon might be VZW, Rogers Canada might be RCI, etc).

So for example: If your phone model is XT1058 and under about phone it reports...

android version is 4.4.4

system version is 212.44.26. ghost_row.RCI.en.ca

build nunber is KXA21.12-L1.26

That tells me you have a Rogers Canada (RCI) XT1058 with 4.4.4 ROM on it. When you look at the file factory site for your SBF, you want to look for a file that contains some/all of that info, like... XT1058_RCI-CA_4.4.4_KXA21.12-L1.26_59_cid14_CFC_1FF.xml.zip

(notice the parts of the "about phone" info and file name which are highlighted in Bold to help illustrate the example)

IF you are already running a CUSTOM or 3Rd party rom, like CM, system version and build number will not match STOCK Moto SBF files

2. Where do all these SBF files come from?

As mentioned earlier, Moto does make the Dev Edition "recovery images" (in SBF format) available on their web site. For all others, the only way for us to get firmware files, is for a copy to be LEAKED to us.. The "Leaked" firmwares are files that are basically "stolen" by a Motorola or wireless carrier employee, who then posts the file on the internet for us... So we can't always count on this ever happening, nor can we have any expectations that a particular firmware will actually get leaked, or when it will be leaked.

There is some talk about using Motorla Device Manager (MDM) app to upgrade your phone, and how during the update process, the app downloads the full FXZ (another term for SBF) to your PC, so it could be copied/saved to another folder for use later. I have not done this with MDM.

EDIT: As of 12/12/14, Only the filefactory.com link is working. The others appear to be down. I don't know the owners of the sites, so I can't say if they will return or not.

EDIT2: As of 1/2/15, motofirmware.com seems to be back up, but sbf.droid-developers.org appears to be gone.
