Samsung ROM AutoPatch Method [Self Create File]

🔧 Samsung ROM AutoPatch Method

If you’re into Android tweaking or repairing Samsung phones, you might’ve heard about the AutoPatch method. It’s a powerful trick to modify the stock firmware — especially the system and vendor partitions — to root the phone, add custom tweaks, or even enable ADB features.

Let me break down the entire process I personally follow. No complicated theory, just practical steps that work.

🛠️ Step 1: Dump System and Vendor Partitions

Start by connecting the phone via USB and enabling ADB. Then open your terminal or CMD and enter:

1. adb shell
2. su (to gain root access)
3. adb shell again

Now, find your block partitions by typing:

ls -al /dev/block/platform/

Then go deeper:

ls -al /dev/block/platform/13520000.ufs/by-name

Once you spot the system and vendor partitions (for example, sda26 is usually vendor), dump them using:

dd if=/dev/block/sda26 of=/sdcard/vendor

Do the same for the system partition.

Now copy both dumped files (system and vendor) from your phone’s internal storage to your PC.

💾 Step 2: Convert to IMG Files

Rename the files to:

• system.img
• vendor.img

If the files are in sparse format, convert them using a tool like simg2img. Most of the time, they’re ready to use.

📂 Step 3: Prepare the AP File

Now take your original AP file from Samsung stock firmware.

1. Extract it using 7-Zip or WinRAR.
2. Inside, find the original system.img and vendor.img.
3. Replace both files with your modified versions.
4. Repack the AP file back into TAR format and save it as AP_Patched.tar.

🔧 Step 4: Magisk Patch for Root Access (Optional)

If you want to root the device, do this:

1. Transfer AP_Patched.tar to your phone.
2. Open the Magisk app and select the AP file.
3. Tap "Patch", and it will create a new file called magisk_patched.tar.

Copy the patched file back to your PC.

🔁 Step 5: Final File Replacement (If Needed)

If you want to make additional changes, extract the Magisk patched file, replace the system and vendor files again, and repack the AP file one more time.

This step is optional but useful if you want full control over both Magisk and your modified files.

🚀 Step 6: Flash Using Odin Tool

Now flash the modified firmware with Odin:

1. Boot the phone into Download Mode
2. Open Odin tool on your PC

3. Load the following:

   • BL (from stock firmware)
   • CP (from stock firmware)
   • CSC or HOME_CSC (from stock firmware)
   • AP → Select your final patched AP file

Click Start and let it flash.

✅ Done!

Your phone should now boot up with:

• A custom patched system and vendor image
• Root access (if Magisk was applied)
• Your custom modifications already included

⚠️ Important Notes

• Always make a full backup before doing this.
• Make sure you’re using the correct partition names like sda26 — these can vary by device.
• If anything goes wrong, just flash the full stock firmware to recover.
