G925a Root 70 Exclusive Work

: The model-specific modified engineering kernel ( .tar.md5 ).

Brief summary of rooting challenges on Qualcomm Snapdragon devices with locked bootloaders (AT&T variant). Focus on firmware version “70” (e.g., Nougat 7.0) and an “exclusive” method — likely exploiting a kernel vulnerability (e.g., CVE-2016-5195 Dirty Cow, or a Samsung-specific bug).

, which allow a simple Odin flash of custom recovery, AT&T variants require an exclusive, multi-stage workaround. This process uses a combination of an engineering kernel, Odin, and custom systemless root scripts to bypass strict carrier restrictions.

Upon rebooting, the phone may lag significantly. This behavior is normal for devices running an engineering kernel.
