There is no leaked 4.4.4 full SBF yet. In a couple weeks, maybe a month it will probably be released.
As long as you never downgraded from a higher version to the german 4.4.2, you can take the OTA without risk. You will need stock Recovery, no Xposed, and no significant modifications made to /system.
Assuming you are full stock and haven't made modifications, the OTA should install without issue.
We will need more details to properly advise you.

If you used RSDLite and fully flashed the SBF to your phone, or used mfastboot and flashed ALL PARTS to your phone, you are safe to take whatever 4.4.4 OTA is pushed to you.
If you only flashed "parts" and have mixed versions (system.img from one rom, no-hols.bin from another, etc), then you need to be careful.. or if you have one version on your phone and try to downgrade it to a lower version.
As @samwathegreat said, there is no leak of a 4.4.4 SBF yet, (well the Verizon one has but we would not recommend flashing it on anything but a Verizon XT1060 phone)
The guys that maintain http://sbf.droid-developers.org/phone.php?device=0 do a great job FINDING the full SBF files, and posting them as soon as they get their hands on them. But since that site isn't owned, operated or supported by Moto, we have no way of knowing how long it will take for the SBF's to show up.

If you have flashed modem files from a different rom than the rest of your phone, any OTA will likely fail its pre-validation checks.
Mixing parts of two different roms isn't advised. Taking updates can fail, brick your phone, or cause other unexpected results.
Sure, there are one or two who say they've done it and are "fine" but we've seen enough posts to know the next OTA, next time they flash, they will likely encounter issues.
My advice. stay with what you have, and wait for the 4.4.4 SBF for the model/carrier you have, and fully flash it. It is the SAFEST way to go.

@KidJoe:
my position is to have flashed in manual ALL PART of SBF 4.4.2 en.DE
Need only to reflash the modem from 4.4.2 TMOBILE because the gsm phone doesn't work (no signal)
so I don't make any mix with more roms. only stock en.De (all parts) and the modem from tmobile.
I received the ota update for 4.4.4 retail en.DE ...
do you think it's safe to install, or as you said, await the full firmware 4.4.4 SBF ?
do you know where, eventualy, I can find tmobile modem 4.4.4 to flash ?
if can't find the 4.4.4, the 4.4.2 tmobile modem (that now I use with success ) do you think is good or not to works in 4.4.4 firmware en.DE ?
thanks again

hi Daniel,
I flashed manual in fastboot ALL part of 4.4.2 files from SBF en.DE (not use RDS)
as you say me, the radio modem doesn't works and flash the tmobile modem (like you send me) and all is OK
now received notification about OTA to 4.4.4 (en.DE)
so, you think it's safe to download ota abd update ?
if radio not work, reflash manual the fsg.mbn and NON-HLOS.bin that I've, right ?
Thanks for reply Danny
EDIT :
I'm on 4.4.2 en.DE stock but ROOTED an with xposed modules and TWRP recovery ....
any problems to install ota ?

Hello,
I have the same problem. I bought a US Moto X Dev Ed. and flashed the german retail with the instructions from this thread: http://forum.xda-developers.com/moto-x/development/update-xt1058-to-android-4-4-2-uk-t2628381
Is it right that I should not accept the OTA because I deleted the modem lines?

4.4.4 xt1053 EMMC error

I flashed all the way back to stock using fastboot and mfastboot to the 1053 4.4.3 firmware. When I tried to install the 4.4.4 OTA, I received the EMMC error. I'm using a 1053 on AT&T. Could it be that I had flashed the AT&T 4.4.4 then going back to 4.4.3 that could be causing the error?

Yes. Downgrade is a no no. Post all details.

I was on stock 4.4.3 and flashed a pre-rooted 4.4.4 AT&T image in TWRP. I had read somewhere that the BL's were the same between the two versions. I didn't like the AT&T version, so I flashed back to 1053 4.4.3. The phone has been working just fine. Now, I can't upgrade to the 1053 4.4.4 OTA update. Should I just wait for the SBF file to become available?

A ROM flash doesn't equal a firmware downgrade. RSD going downward is the problem.
But once on a custom recovery you need to backup your virgin "rom" to save it for any future OTA!

Hi, I have a unrooted 1092 where I applied the OTA to 5.0.

Hey Ivar,
You've got 2 choices; use mfastboot to revert back to KitKat. So you must unlock your bootloader. Or try motorola's RSD Lite tool..
I recommend making a full nandroid back up before attempting anything.
Check here; techbeasts.com/2014/11/11/how-to-restore-moto-x-2014-to-stock
If you need any help, let me know! Good luck !
Btw, Motorola stock rom's are called SBF's ( system binary file )

there is a high risk of bricking your device while downgrading http://forum.xda-developers.com/moto-x/general/info-warning-risks-downgrading-impacts-t3058202

It's highly risky to downgrade but if you persist just make sure your bootloader and partition table is not the one that got upgtaded with the latest 5.1 rom. If it is the latest then don't do it.

You can downgrade completely to 4.4.4.
But don't take OTA, your phone will brick.
The safest way in my opinion is (if you want to downgrade);
- Flash entire official firmware of XT1060 to your phone.
- DON'T TAKE OTA
- Wait for full firmware of XT1060(5.1)
- Flash full firmware of XT1060(5.1)
But if you want to play with 5.1, you can try this;
In my case, I have XT1056, and I wanted to play around with 5.1, so I converted from XT1056(4.4.4) to XT1053(4.4.4), then took OTA to XT1053 (5.1).
After that I tried AOSP but my bluetooth headset had a problem with phone function, then I decided to go back to official firmware again.
Since there is no Lollipop image for XT1053 or XT1056 now, I had to flash another variants like XT1052 and XT1058, but I got no signal.
I had to downgrade to XT1056(4.4.4) and using it for a day. After that I found out that file size of fsg.mbn differ by variants, then I downloaded XT1053(5.1 OTA) to get it.
I mixed up an entire XT1052(5.1 retail EN) with fsg.mbn from XT1053(5.1 OTA) and flashed them manually. Now my XT1056 works very well (with Xposed framework).
Keep in mind that YOU DO THIS ON YOUR OWN RISK.

My situation is same with you. My phone is xt1056 sprint. I converted to xt1053, and got ota to 5.1. But I don't like stock 5.1,there are some bug with graphic... I flashed and used customs Rom CM, PA,Carbon...some day. But now, I want to come back 4.4.4. Can you guide me more details?
I think if you flash complete 4.4.4 from 5.1, phone will bricked, because bootloader can not downgrade as someone said in high risk ...topic. Maybe you can flash 4.4.4 fw with edit xml to NOT flash motoboot and gpt....
Right ?
And last question, if there is a method to flash back 4.4.4, can I flash 4.4.4 xt1053 ? I don't want my phone have many bloatware sprint xt1056.

You can flash back to 4.4.4 of XT1053 or XT1056 as you prefer, I think their radio are compatible.
But when 5.1 comes out, DON'T TAKE OTA. You have to wait for a full firmware to upgrade your phone.
I always use a manual flash method, so I don't have to edit an xml file.
When you downgrades, you will see a warning message, just ignore them.

Do you use fastening to flash fw? And you flash all part inside fw? Include motorboat and got... ? After flash, do you make unlock network again ?

I used mfastboot to flash all CGs to my phone. But you may try to skip some CGs like KidJoe said.
Every time when you return to stock or do a hard reset, you have to do the SIM-unlock process again.

Moto is no longer including the XML to flash via RSDLite, but you could make your own if needed... instead they include a BATCH file which calls a copy of Moto's fastboot to flash it.
That being said... I WARN YOU!!! You will risk bricking your phone if you attempt to downgrade. While there is a slight chance the phone will not brick, we have enough who have bricked to say it is not safe!!
Some will say... "its ok, just skip motoboot.img and gpt.bin when flashing" that isn't safe either. If you later get prompted for and take an OTA update you'll again likely brick. Further when motoboot.img and GPT.BIN are missmatched from the rest of a STOCK Moto rom we've seen "bugs" or "issues" of things no working, like speaker phone, Settings -> Security menu, etc which are not a problem when all parts of your phone are consistent.
You're best bet... wait until a full 5.1 SBF for the Verizon XT1060 is either posted to Moto's web site of Dev Edition Images, or wait until a copy leaks... however, that too many also fail *IF* the GPT.BIN and components of motoboot.img are newer or different in the build you are running compared to what is made available as the XT1060 5.1 SBF.

That's true. You can not downgrade, if you are on a light, official side. But if you want to try dark side - flash your Asia region 4.4.4 without "gpt" and "motoboot" lines in its XML file. Once flashed 4.4.4, you can take OTA 5.1 on it without any problem.
A message to future users. Being on 5.1.1, then downgrade to 4.4.4, and taking 5.1 OTA - will brick. Don't do that.
