MultiRoot Flashable ZIP

One recovery-flashable ZIP installs KernelPatch + Magisk root — then whichever root manager app you install (FolkPatch, APatch, or Magisk) manages it. Flash in TWRP/OrangeFox, reboot, done. Ships with a matching Uninstaller ZIP that removes everything without needing or creating a single backup file.

TL;DR: KernelPatch 0.13.8 kernel patch (→ FolkPatch + APatch managers) + Magisk 30.6 ramdisk patch (→ Magisk app) — two root providers active from one flash. See the KSU section for KernelSU support status.

Which file do I need?

File	Use it when…
MultiRoot-v2.1-Recovery-Installer.zip	You want root: flash in recovery, reboot, done ✅
MultiRoot-v2.1-Uninstaller.zip	You want to unroot: no backup needed
SHA256SUMS.txt	Verify downloads before flashing

All three official manager APKs (me.yuki.folk FolkPatch + APatch + Magisk Manager) are bundled inside the ZIP — the installer copies them to sdcard for you automatically.

Requirements

Requirement	Notes
Android device (Android 6.0 to 15+)	Supported (ARM64 & 32-bit ARM)
Custom recovery (TWRP / OrangeFox / Lineage)	Required — adb sideload works too
CONFIG_KALLSYMS=y in the kernel	Optional — Enables KernelPatch (FolkPatch/APatch); if missing, Magisk provides full universal root
Unlocked bootloader	Required
Battery ≥ 50%	Recommended

Works on A-only, A/B, and Virtual A/B devices. The kernel always lives in the boot partition — vendor_boot is never touched.

How to flash

1. Copy the ZIP to your sdcard / storage.
2. Recovery → Install → select the ZIP (or adb sideload it).
3. The installer will:
   • Detect the boot partition and slot automatically
   • Unpack the boot image and patch the kernel with KernelPatch (superkey: su, if supported)
   • Patch the ramdisk with Magisk (on Android 13+ GKI devices where boot has no ramdisk, Magisk goes to init_boot instead)
   • Clean any existing patch first, so re-flashing is always safe
   • Flash directly → verify by reading the partition back → print ROOT ACTIVE / MAGISK ACTIVE
   • Copy FolkPatch-Manager.apk, APatch-Manager.apk, and Magisk-Manager.apk to sdcard
4. Reboot → install any one manager:
   • Magisk-Manager.apk (sdcard) → manages Magisk root, grants superuser to all apps
   • FolkPatch-Manager.apk (sdcard) → shows Installed/Active
   • APatch-Manager.apk (sdcard) → manages the KernelPatch kernel
   • KernelSU app / other root managers → gets root permission via su
5. Grant Superuser per app inside whichever manager you use.

Mode selection (optional)

Default mode is all (KernelPatch + Magisk together). Want only one? Create root-mode.txt on sdcard with a single word:

Mode	What gets installed
all (default)	KernelPatch + Magisk — both active
kpatch	KernelPatch only — FolkPatch / APatch managers
magisk	Magisk only — Magisk app

Then re-flash the same ZIP: the installer cleans the old patch and applies the new mode. /data/media/0/root-mode.txt and /external_sd/root-mode.txt work as fallbacks.

Uninstall / unroot

Flash MultiRoot-v2.0-Uninstaller.zip in recovery. It:

• KernelPatch → live kernel unpatch via kptools -u (no backup required)
• Magisk → restores the ramdisk from the internal .backup stored inside the patched boot image itself
• Restores the Magisk ramdisk in init_boot too, if present
• Removes every root file from /data: FolkPatch/APatch daemon (/data/adb/ap*, /data/adb/fp), Magisk (/data/adb/magisk*, modules, post-fs-data.d, service.d), KernelSU (/data/adb/ksu*), plus any old FolkPatch-Backup folders and flash reports
• Verifies by reading the partition back and prints STOCK CONFIRMED

Uninstall the manager apps manually from Android settings afterwards.

About KernelSU managers

KernelSU / KernelSU Next / SukiSU managers do not work with this ZIP, because:

• The KernelSU family needs its code compiled into the kernel, and that requires a prebuilt kernel/LKM matching your exact kernel version (KMI) — impossible to bundle in a universal ZIP.
• Want KSU anyway? The KSU-Next/SukiSU manager app can install its own LKM/GKI image for your device from its "Install" page — that is a separate step.
• The Uninstaller still cleans KernelSU /data/adb leftovers for you.

One flash gives you FolkPatch + APatch + Magisk — three manager families can be active at once. Using one manager as your primary is still recommended (see FAQ).

---

Backup policy: not a single backup file is created

The old v1 installer created FolkPatch-Backup/ folders, ori.img, and flash reports. None of that exists anymore — and stale files from v1 are deleted when you flash the installer or uninstaller:

• No stock-*.img / boot.img copies are written to sdcard or /data
• All patch work happens in /tmp (RAM/tmpfs) and is deleted at the end
• Magisk uninstall relies on the .backup inside the boot image itself — not on any external file
• If you want a stock boot.img copy for extra safety, keep one yourself from your firmware package — this ZIP will not.

Troubleshooting

Symptom	Fix
No ROOT ACTIVE in the recovery log	The flash didn't reach the partition — flash the Uninstaller and retry
Manager shows "Not installed"	Install the APK from the ZIP (sdcard copy), reboot, open again
kernel requires CONFIG_KALLSYMS=y	This kernel cannot be patched — root is impossible on it
new-boot.img missing / repack failed	ZIP damaged — re-download and verify SHA-256
Bootloop	Flash the MultiRoot Uninstaller ZIP (or fastboot flash boot your stock boot.img)
su: not found in adb shell	Normal — FolkPatch/APatch have no /system/bin/su; grant per-app inside the manager
Both KP and Magisk installed — which su wins?	Both daemons run; which su appears in a terminal depends on boot-time mount order. Per-app grants follow the manager you granted in

FAQ

Is this official? No — a community repackaging. FolkPatch: LyraVoid, KernelPatch: bmax121, APatch: bmax121/APatch, Magisk: topjohnwu/Magisk. All binaries come from the official upstream releases and are SHA-256 verified at build time; the installer scripts are original work from this repo (GPL-3.0).

Do I need to enter a superkey? No. The kernel is patched with the fixed superkey su; the FolkPatch/APatch managers authenticate by APK signature. There is no key screen.

Can I install all three manager apps? Yes — but using one as your primary is recommended. With both Magisk and KP active, one daemon owns /system/bin/su depending on mount order; each daemon still handles the apps you granted in its own manager.

Will it trip Play Integrity / SafetyNet? Root inherently affects attestation — use Shamiko/SUSFS-style hiding modules and the manager's denylist. No guarantees.

Does adb sideload work? Yes — each ZIP contains exactly one script, so dispatch works under sideload too.

How it works

Component	Role
META-INF/.../update-binary	Recovery bootstrap: busybox setup, picks the script by ZIP name
assets/InstallMultiRoot.sh	Read boot → unpack (magiskboot) → Samsung hexpatches → KernelPatch kernel patch → Magisk ramdisk patch → repack → flash → readback verify → daemon → sdcard APKs → temp cleanup
assets/UninstallMultiRoot.sh	Read boot → live KP unpatch → Magisk in-image restore → repack → flash → verify → /data root-file cleanup
assets/kpimg	KernelPatch core (0.13.8) embedded into the kernel
lib/arm64-v8a/libkptools.so	KernelPatch CLI (patch/unpatch/verify)
assets/magisk/*	Official Magisk 30.6 payload (magiskboot, magiskinit, magisk, init-ld, stub)
FolkPatch.apk / APatch.apk	Official manager APKs — copied to sdcard after flashing

kptools and magiskboot are bionic-linked, so the scripts mount the real system + APEX runtime in recovery, run the tools, then restore the environment.

Build from source

No binaries are committed. The build extracts everything from the three official APKs (SHA-256 verified) and packs both ZIPs:

python tools/build.py --tag v2.0
# output: dist/MultiRoot-v2.0-Recovery-Installer.zip
#         dist/MultiRoot-v2.0-Uninstaller.zip
#         dist/SHA256SUMS.txt

Pushing a v* tag makes GitHub Actions build and attach the ZIPs to a release automatically.
