I'm sure someone here can explain better than I can, but I've read time and time again don't downgrade, there is the risk of bricking

Yes, as @M973 has advised, you can not "safely" downgrade back to 4.4.2. The reason is that "gpt.bin" - the partition table can NOT be downgraded. Even if you are able to manually downgrade the rest of the partitions to 4.4.2, you will still have a mismatched gpt.bin, and hence will be at risk of bricking the next time you take an OTA.

Once the 4.4.3 or higher SBF for retail Argentina is released, you CAN safely flash it, without risk of bricking.

Is it normal for the ota to have been reelased and still no sign of the 4.4.3 SBF on motorola site?

Yes, it is completely normal. Usually, the SBF is not released for days, weeks, or sometimes even months after the OTA comes out.

I went from 4.4.3 Retail Brazil to 4.4.2, it is possible, yes, you may have a gpt.bin mismatch but at the end I took the 4.4.3 OTA and 4.4.4. And it is working fine. The reason I had to downgrade was that my 4.4.3 was rooted and with xposed and uninstalling and flashing stock recovery did not work while booting the 4.4.4 OTA.

So it can be done but with precaution.

Define Moto's site.

For example -> http://sbf.droid-developers.org/ is neither owned, nor operated, nor sponsored, nor connected to moto in anyway. Its hosted, run, maintained by some "guys" who come across or otherwise FIND the SBF files, and post them. SBF/FXZ files do not appear there until they are found or leaked. How long that takes has no pattern.

On the other hand... This site -> https://motorola-global-portal.custh...ecovery-images *IS* owned and operated by Motorola. It contains the recovery images for the Developer Edition phones (XT1053 and XT1060... note these images also work for the equivalent Non-Dev XT1053 and XT1060 from moto maker and "retail"). Moto posts the images, but it seems its usually AFTER that particular android version has been rolled out to all models in all locations (i.e. the 4.4.2 SBF for the GSM and VZW Dev Edition X didn't show up on Moto's site until after the roll out to 4.4.2 was done on all carriers to all X models, even non-Dev Edition devices).

@ramarivera : It is your phone, so you can do with it as you would like. Keep in mind that although the procedure worked for that individual, if you try this, you are doing so at your own risk.

I wish you the best of luck.
