Prerequisites & Important Warnings​

• Bootloader Unlock: Bootloader must be unlocked via OEM Unlocking and Device Unlock Mode.
• Knox Trip Warning: Flashing custom binaries permanently trips the Knox warranty bit (0x1), permanently disabling Knox-dependent services (Samsung Pass, Secure Folder, Samsung Wallet/Pay).
• Data Loss: Unlocking the bootloader and performing data formatting wipes all user data. Back up all important files beforehand.
• Required Files & Tools:
  
  • Odin3 (v3.14.4 or latest).
  • Official Samsung Mobile USB Drivers installed on PC.
  • Verified twrp-a35x-exynos.tar file.
  • vbmeta_disabled.tar to bypass Android Verified Boot (AVB).
  • Multidisabler / Magisk ZIP file to disable dynamic filesystem encryption.

Step-by-Step Installation Instructions (Nasıl Yüklenir?)​

Step 1: Unlock Bootloader​

1. Go to Settings > About Phone > Software Information and tap Build Number 7 times to enable Developer Options.
2. Navigate to Settings > Developer Options and toggle OEM Unlocking and USB Debugging to ON.
3. Power off the phone completely.
4. Press and hold Volume Up + Volume Down simultaneously, then connect the phone to your PC via a USB cable.
5. On the warning screen, long-press Volume Up to access the Device Unlock Mode. Confirm the unlock (this wipes all user data and restarts the device).
6. Complete basic initial setup, connect to the internet (Wi-Fi), and verify in Developer Options that OEM Unlock is greyed out and reads "Bootloader already unlocked."

Step 2: Boot into Samsung Download Mode​

1. Power off the device completely.
2. Press and hold Volume Up + Volume Down together while connecting the USB cable to your PC.
3. Press Volume Up once briefly to enter Download Mode (Odin Mode).

Step 3: Flash TWRP & Patched VBMeta via Odin​

1. Launch Odin3 as Administrator on your PC. The ID:COM box will light up in light blue.
2. In the USERDATA slot, select vbmeta_disabled.tar.
3. In the AP slot, select your twrp.tar file.
4. Go to the Options tab in Odin:
   
   • Keep F. Reset Time checked.
   • Uncheck Auto Reboot (Essential: Prevents One UI from overwriting TWRP with the stock recovery on the first reboot).
5. Click Start to flash and wait for Odin to display the green PASS! status.

Step 4: First Boot into TWRP & Disable Encryption​

1. Unplug the USB cable.
2. Force restart the device by holding Volume Down + Power.
3. The exact instant the screen turns black, quickly switch your fingers and hold Volume Up + Power (keep connected to PC or USB-C headphones if your One UI version requires a USB handshake to trigger recovery).
4. Release the buttons once the TWRP splash screen appears.
5. Inside TWRP:
   
   • Go to Wipe > Format Data, type yes, and confirm (removes dynamic file-based encryption).
   • Go to Reboot > Recovery to remount partitions cleanly.
   • Flash Magisk.zip or a multidisabler zip via Install to maintain root privileges and prevent stock recovery overwrite.
6. Select Reboot > System.
