WARNING WARNING WARNING
It is strongly NOT recommended to flash the leaked Retail Brazil soak test OTA on your phone, especially if you have a non Retail Brazil variant. Here are the risks of flashing it on the different variants:
1. Flashing it on a Retail Brazil xt1058 variant:
This is still a soak test and might not be the final release. So if moto release another soak test, you would need to flash the delta file manually to update to the final release, you wouldn't be able to take it OTA. If no one leaks this delta file, you might get stuck on this unfinished release until the full 5.0.2 factory image is available because you might not be able to downgrade to take the proper OTA from 4.4.4.
2. Flashing it on a non Retail Brazil xt1058 variant or an xt1053 variant:
You would need to "convert" your phone to a Retail Brazil xt1058 first by flashing the full 4.4.4 Retail Brazil factory image before flashing the 5.0.2 OTA. So everything I said in point number 1 above applies and on top of that, you wouldn't be able to revert back to your stock image until your full 5.0.2 factory image is available. Again, you might get stuck on this unfinished release.
3. Flashing it on an xt1052 variant:
The xt1053/xt1058 factory images are not compatible with the xt1052 because of the different modem hardware. So flashing the xt1058 4.4.4 Retail Brazil factory image on your xt1052 would break radio (phone) functionality. You would then have to reflash the modem files from your xt1052 4.4.4 image after flashing the 5.0.2 OTA. This means that you would be using 4.4.4 modem files on a 5.0.2 image which might be unstable. This would also mean that you wouldn't be able to take OTA's anymore unless you revert back to stock because of the mismatched files. You would also not be able to revert back to stock until your full 5.0.2 factory image is available. You wouldn't want to be stuck on this unfinished release.
YOU'VE BEEN WARNED!!!
