Unlock Bootloader
Wipes everything. Samsung Knox trips permanently on unlock — no way back.
8 steps ▼
- Back up all data — unlocking factory resets your device
- Enable Developer Options: Settings → About Phone → tap Build Number 7 times
- Enable OEM Unlocking in Developer Options
- Enable USB Debugging in Developer Options
- Connect to PC: adb reboot bootloader
- Unlock: fastboot flashing unlock (older: fastboot oem unlock)
- Confirm on device screen — wipe happens immediately
- Device reboots to stock setup wizard
Install TWRP Recovery
Use the exact TWRP build for your device model number. Wrong builds can brick.
5 steps ▼
- Download TWRP .img for your exact device variant from twrp.me
- Boot to fastboot: adb reboot bootloader
- Flash: fastboot flash recovery twrp.img
- Boot into recovery immediately: fastboot boot twrp.img
- In TWRP swipe to allow modifications
Install OrangeFox Recovery
OrangeFox is only available for select devices.
4 steps ▼
- Download OrangeFox .img for your device from orangefox.tech
- Boot to fastboot: adb reboot bootloader
- Flash: fastboot flash recovery orangefox.img
- Boot into recovery: fastboot boot orangefox.img
Flash Custom ROM
Never mix incompatible GApps versions. Read the ROM thread for device-specific notes.
7 steps ▼
- Unlock bootloader and install custom recovery first
- Download ROM zip and GApps zip (if needed) to your device
- Boot into recovery (TWRP or OrangeFox)
- Wipe: Factory Reset → Data, Cache, Dalvik/ART cache
- Flash ROM zip: Install → select zip → Swipe to Flash
- Flash GApps zip in the same session before rebooting
- Reboot System — first boot takes 3-10 minutes
Root with Magisk
Keep a backup of the original boot.img. Magisk is systemless — safer for updates.
7 steps ▼
- Unlock bootloader first
- Download stock boot.img for your exact firmware build
- Install Magisk app on device
- In Magisk: Install → Select and Patch a File → pick boot.img
- Copy patched_boot.img to PC
- Flash: fastboot flash boot patched_boot.img
- Reboot and open Magisk to verify root
Root with KernelSU
Requires kernel-level support. Not all devices are supported.
5 steps ▼
- Check kernelsu.org for a supported kernel for your device
- Download the KernelSU kernel .img
- Flash: fastboot flash boot kernelsu_boot.img
- Install KernelSU Manager from GitHub releases
- Grant root from the Manager
Root with APatch
Alternative to Magisk with kernel patch support.
5 steps ▼
- Download APatch from github.com/bmax121/APatch
- Extract boot.img from your stock firmware
- In APatch app: patch boot.img
- Flash patched boot: fastboot flash boot patched_boot.img
- Reboot and verify in APatch Manager
Restore Stock / Unbrick
Always use firmware matching your exact region and model number.
7 steps ▼
- Download official stock firmware for your exact model and region
- Samsung: use Odin — flash AP/BL/CP/CSC files
- Xiaomi/Poco: use MiFlash in EDL/fastboot mode
- Google Pixel: use Android Flash Tool at flash.android.com
- OnePlus: use MSM Download Tool for hard bricks
- Other devices: check XDA for your specific model
- After flash: device reboots to stock
Buying & Selling Modified Devices
Unlocked bootloader = lower resale value. FRP locks are illegal to bypass on a device you don't own.
7 steps ▼
- BEFORE SELLING: Factory reset and remove Google account (FRP)
- BEFORE SELLING: Restore stock ROM and re-lock bootloader if possible
- BEFORE SELLING: Disclose Knox trip status to Samsung buyers — it shows in settings
- BEFORE BUYING: Ask if bootloader is unlocked
- BEFORE BUYING: Check IMEI on imei.info — confirm not blacklisted
- BEFORE BUYING: Test camera, speakers, fingerprint, charging
- BEFORE BUYING: Verify model number matches your region
