Root My Galaxy Payloads

This repository contains the device-specific native side of Root My Galaxy:

• exact firmware profiles and offsets;
• the app-domain CVE-2026-43499 exploit source and compiled payload;
• the app bootstrap helper source;
• the verified KernelSU late-load build artifacts;
• the support feed consumed by the application.

It intentionally does not contain Android application source code.

Supported payloads

Payload	Compatible models	Kernel version	Status
galaxy-s25-series-2026-06-07	Galaxy S25, S25+, S25 Edge, and S25 Ultra regional models	6.6.98	Device-tested
e3q-S928USQS6DZF2	Galaxy S24 Ultra SM-S928U1	6.1.145	Device-tested
e2s-S926BXXUEDZDR	Galaxy S24+ SM-S926B	6.1.157	Device-tested
essi-A566EXXSCCZG6	Galaxy A56 5G SM-A566E	6.6.102	Device-tested
a36xq-A366WVLS3AYG1	Galaxy A36 5G SM-A366W	6.6.46	Device-tested
a53x-A536EXXSNGZG3	Galaxy A53 5G SM-A536E	5.10.237	Device-tested
dm3q-S9180ZHS8FZF5	Galaxy S23 Ultra SM-S9180	5.15.189	Test in progress
dm2q-S916BXXSAFZG1	Galaxy S23+ SM-S916B	5.15.189	Experimental: hardware root from ADB shell; not in app feed
dm3q-S918BXXSAFZF5	Galaxy S23 Ultra SM-S918B	5.15.189	Confirmed working: full chain through the app (Shizuku mode) incl. KernelSU late-load and granted su
The Android 17 beta S928USQU6ZZHL profile is currently withdrawn from the
support feed. Both the generic and legacy-shaped KernelSU Next module pairs
crashed the phone during late-load; their binaries are retained only under
kernelsu/quarantine/ for forensic analysis. The app payload and target
constants remain in the repository, but Root My Galaxy will not automatically
select or download a ZZHL payload until an exact kernel-compatible module can
be built and validated.

The S916B FZG1 profile is shell-only today. Its exact tracefs route works from adb shell, but direct app-domain execution is not supported. Root My Galaxy would need to delegate the native runner through an authorized shell bridge such as Shizuku. See artifacts/dm2q-S916BXXSAFZG1/README.md.

The S918B FZF5 profile is hardware-verified through the app's Shizuku mode (exploit, KernelSU late-load, granted su under enforcing). Its physical-P0 fallback also engages in unprivileged app-domain execution, but rooting without Shizuku is not yet hardware-confirmed. See docs/SM-S918B-S918BXXSAFZF5.md.

Schema version 3 keeps each exploit and KernelSU artifact once. Its flat models and kernelVersions arrays define runtime compatibility. See support/README.md for the matching rules.

The port is based on the exploit source published at https://github.com/NebuSec/CyberMeowfia/tree/main/IonStack/CVE-2026-43499/exploit.

Feed delivery

Root My Galaxy resolves the payload repository's current commit first and fetches support/targets-v3.json and every artifact from that immutable commit. Per-artifact SHA-256 fields and manifest signatures are not part of schema version 3. targets-v2.json is retained for released 0.2.3 clients.

The complete firmware-to-profile procedure is recorded in docs/PORTING.md. Samsung-specific KernelSU changes and versioned artifacts are documented in kernelsu/README.md. The exact S921B DZF2 analysis is recorded separately in docs/SM-S921B-S921BXXSFDZF2.md, and the S928U/S928U1 DZF2 analysis is in docs/SM-S928U1-S928U1UES6DZF2.md. S921B is an Exynos 2400 target and is not a Qualcomm/Snapdragon reference for E3Q. The 5.10 A15 analysis is in docs/SM-A155N-A155NKSS6BYH1.md. The SM-A566E CCZG6 analysis and validation record is in docs/SM-A566E-A566EXXSCCZG6.md. The SM-S926B DZDR analysis and device-validation record is in docs/SM-S926B-S926BXXUEDZDR.md. The SM-A366W AYG1 device validation is in docs/SM-A366W-A366WVLS3AYG1.md. The experimental SM-S916B FZG1 shell port and its exact hardware evidence are in docs/SM-S916B-S916BXXSAFZG1.md. The SM-A536E GZG3 device validation is in docs/SM-A536E-A536EXXSNGZG3.md.
