I wanted to be clear on what things would brick my phone for sure, that way I don't do them. First of all is it the bootloader or the system image that causes it to brick? If it's the bootloader, would I be able to just flash the system image by itself then do the OTA to get me to kitkat? Or is the camera file that is in the system image the problem? If so is it possible to modify the system image to update just the camera file then flash it then do the update to kitkat? Am I able to flash another rom from another carrier such as "Claro Brazil" or "Claro Puerto Rico" since they have the same system version as my phone(139.12.35.ghost_row.America.Movil.en)? Or would that brick it?
Or if any android or moto x gurus have any other ideas on how I can get to kitkat I am open to suggestions and ideas.
