SamsTool Online v1.31 Released The Z3X Evolution Arrives

The landscape of Samsung servicing is shifting rapidly. Just months after the initial release of SamsTool Online, the development team has dropped version v1.31, bringing with it a host of critical improvements and expanded support for the latest EDL loaders. This isn't just a maintenance update; it is a continuation of what is rapidly becoming the "Chimera Killer" in the GSM industry—a tool that combines the legendary reliability of the Z3X Samsung Box with modern, cloud-based agility.

For technicians tired of monthly subscriptions and token-based unlocking for Exynos devices, this update reinforces the tool's commitment to a one-time activation model that offers nearly unlimited freedom. Let’s dive into what’s new in v1.31, the broader feature set, and how this tool is handling the latest security challenges from Samsung.

What’s New in SamsTool Online v1.31?

The v1.31 update focuses on precision and expanding the toolkit for advanced network operations. While previous updates broadened device compatibility, this release hones in on user control during relocking procedures and backend EDL support.

Key Updates in This Release:

Manual MCC/MNC Input: You can now manually input Mobile Country Code (MCC) and Mobile Network Code (MNC) during carrier relock operations. This is vital for technicians restoring devices to specific regional carriers where automatic detection fails.
New BIT EDL Loaders: Significant support has been added for new Binary Information Table (BIT) versions, allowing for deeper EDL (Emergency Download) access on previously unsupported or "bricked" units.

Key Functional Features

SamsTool Online was designed to replace the physical dongle limitations of the past. By leveraging a powerful online authentication system, it packs an exhaustive list of features into a lightweight interface.

Unlocking Capabilities:

Unlock/Relock Bootloader: Essential for rooting or restoring stock firmware status.
Unlock Network/Region Locks: Direct SIM unlock for a vast range of models.
Read Unlock Codes: Retrieve NCK/MCK codes directly from the server.

Security & FRP:

Reset FRP (Factory Reset Protection): Bypass Google account verification on Android 13, 14, 15, and 16.
Set KG State (Locked/Active): Manipulate the Knox Guard state without needing certificates.
Remove Security Warnings: Clear the "Custom OS" or "System Modified" boot flags.

Repair & Maintenance:

Repair IMEI & Serial Number (SN): Restore null or corrupted IMEIs.
Repair Boot: Fix devices stuck on the Samsung logo or boot loops.
Patch Certificate: Write security certificates to bypass baseband issues.
Update Firmware: Full flashing capabilities via the intuitive interface.
Switch to EUB Mode: A specialized communication mode for enhanced diagnostic and repair operations.

Version Comparison: v1.31 vs. Previous Releases

To understand the trajectory of this software, it is helpful to look at how quickly the SamsTool team is moving compared to competitors.

Feature / Update	SamsTool v1.31 (Current)	v1.29 / v1.28 (Previous)
Relock Operation	Manual MCC/MNC input added	Automatic only
EDL Support	New BIT loaders (SM-F9160, SM-T735, etc.)	Basic BIT support introduced
Android 16	Stable support inherited	New FRP Reset added for Android 16
Connectivity	Optimized	Faster EUB connection speed
Cert Repair	Stable	Added DFTSU support for Patch CERT

Note on v1.20-v1.24: The rapid progression between these versions introduced World First support for Android 15 CERT Patching on models like the A346 and A055, and added the "Relock to Carriers" feature which has now been refined in v1.31.

Practical Scenario: Reviving a Bricked Exynos Device

To illustrate the power of the new BIT EDL loaders in v1.31, let's look at a common workshop scenario.

The Situation:

A client brings in a Samsung Galaxy S21 Ultra (SM-G998U) that is stuck in a bootloop after a failed manual update. The device is an Exynos variant, and standard ODIN flashing fails because the device refuses to enter Download Mode properly.

The Solution:

Force EDL Mode: You force the device into Emergency Download (EDL) mode using the hardware key combination (Volume Up + Down while inserting USB).
Select Model in SamsTool: You launch SamsTool Online v1.31 and select the SM-G998U. The software automatically detects the required BIT version (one of the new loaders supported in the recent updates).
Flash Firmware: Instead of a generic flash, you use the SamsTool "Patch Cert" or "Repair Boot" function specifically designed for this BIT version.
Restoration: The tool utilizes the specific EDL loader to communicate with the phone's bootloader, bypassing the corruption, and successfully writes the bootloader and firmware.
Result: The phone boots up successfully, Knox remains intact (if desired), and the client is happy. Without the new BIT loaders in v1.31, this device might have required a expensive motherboard replacement or a JTAG box.

Newly Supported Models (v1.31 Specific)

The list of supported devices is growing daily. The v1.31 update specifically adds or refines support for the following BIT versions across popular models:

Galaxy S21 Series: SM-G991U, SM-G996U, SM-G998U (Various BIT versions E/F/H).
Galaxy Z Fold/Flip: SM-F711B/U/N, SM-F9160, SM-F926B/U/N.
Galaxy A Series: SM-A235F, SM-A2360, SM-E145F, SM-M145F.
Tablets: SM-T636B, SM-T638U, SM-X216C/N.
