I'm wondering if "how to videos" that discuss rooting, custom recoveries, custom ROMs, etc. should also include a warning about accepting OTA updates?
Lots of Galaxy S3 and S4 users unknowingly accepted OTA updates to find their phones were now hopelessly locked down and no custom recoveries could be installed.
I personally believe ALL carriers want their phones locked down securely and do NOT want anyone to be able to mod a phone in any way and with this belief comes the thought that any phone such as the M8 will sooner or later receive an OTA that will lock the bootloader.
A warning about OTAs couldn't hurt anything...
