Carrier variants
The original DroidKube homepage referenced Moto X root coverage for carriers including AT&T, Verizon, Sprint, T-Mobile, US Cellular, and others. Modern use requires verifying each exact variant.
Risk basics
Root methods are often firmware-sensitive. A working method on one build can fail on another, so always document the software version before making changes.
Checklist
Back up the phone, charge it, use official drivers, research recovery options, and keep fastboot or factory images ready where available.
