with U3 (Binary 3), an "auto patch" file is a modified firmware file typically used to fix network issues—like "Emergency Calls Only" or "No Service"—after performing an IMEI repair or root.
Creating a "full feature" auto patch file involves modifying core partitions to ensure the device remains stable and maintains its network status even after a factory reset. Key Components of an Auto Patch File
To create a high-quality auto patch, you typically need to modify the following partitions from the stock U3 firmware:
AP (System) File: Often contains the modified boot.img, recovery.img, and vbmeta.img files that have been patched (usually via Magisk) to allow for persistent root and network patches.
CP (Modem) File: Sometimes requires a downgrade or a specific version to bypass security checks that block network signals on repaired devices.
Persistent Fix: The "auto" aspect refers to scripts or modifications that prevent the network patch from being erased when the user performs a factory reset from the settings. General Process to Create an Auto Patch
Obtain Stock U3 Firmware: Ensure you have the exact U3 firmware for the
Patch with Magisk: Use the Magisk App to patch the AP file. This provides the necessary root access for the patch to function.
Inject Network Scripts: Advanced users use tools like 7-Zip to open the firmware files and replace specific system or vendor files with patched versions that bypass network locks.
Repackage: The modified files are repacked into .tar or .md5 format so they can be flashed using Odin. Important Considerations

Mastering the Samsung A105F U3 Auto Patch: The Ultimate Guide to Network Repair
If you are dealing with a Samsung Galaxy A10 (SM-A105F) that has a "NG" network status, "Not Registered on Network" errors, or a null IMEI after a firmware update, you likely need a Samsung A105F U3 Auto Patch file.
In the world of GSM repair, the "U3" (Binary 3) version of the A105F is particularly common. Finding an extra quality auto patch file is the difference between a permanent fix and a device that loses signal every time you reboot. What is a Samsung A105F U3 Auto Patch File?
An Auto Patch file is a modified firmware component (usually involving the boot.img or system partition) designed to bypass the RSA signature check on the modem and network certificates. For the A105F U3 (Binary 3), this is necessary when: The device has been repaired via IMEI change.
The network status shows "NG" (No Good) instead of "OK" in the service menu (*#0011#).
You have updated the firmware and the previous network patch was wiped.
"Extra Quality" refers to files that are pre-rooted (often with Magisk) and optimized to ensure the patch remains persistent, preventing "Circle" or "No Service" symbols after a factory reset or long-term use. Prerequisites Before Flashing
Before you download any "extra quality" patch file, verify your device specs to avoid hard-bricking: Model Number: Must be SM-A105F.
Binary Version: Must be U3/S3/B3. You can check this in Download Mode (look for RP SWREV: B:3). OEM Unlocking: Must be enabled in Developer Options. Bootloader: Must be Unlocked. Step-by-Step Installation Guide
