The data connection often toggles out of AT/MTP mode during the exploit phase, causing the software to lose sight of the device. Updated Methods to Fix the "Running Exploit Fail" Error 1. Shift from ADB Mode to MTP Mode
Updates to the device's firmware can also render certain exploits ineffective. As firmware is updated, vulnerabilities that were previously exploitable may be patched.
Recent updates to the tool introduce structural workarounds that allow modifications without relying on older ADB security exploits. Open the program and look for the master horizontal tabs.
: Unpack the package to find files designated as BL, AP, CP, CSC, and HOME_CSC . Boot into Download Mode : Turn off your phone. samfw running exploit fail updated
Often, the exploit fails because the tool can’t communicate properly with the device.
: Samsung Knox flags automated exploit scripts running via unauthenticated USB channels, resulting in a sudden "Stage 1 / Stage 2 Fail" or an indefinite loop hanging on "Running exploit..." .
When this process fails, it is usually due to updated Android security patches, missing driver frameworks, or improper device state synchronization. This comprehensive guide details why this error occurs and provides step-by-step solutions to fix it. Understanding the "Running Exploit... FAIL" Error The data connection often toggles out of AT/MTP

: Click Start and wait for the process to display a green "PASS" status. 2. Disabling Background SIM Managers (Fixes CSC Reverting)
The computer and the phone must communicate seamlessly in AT or MTP mode. Broken, outdated, or unsigned USB drivers disrupt this communication mid-exploit. As firmware is updated, vulnerabilities that were previously
⚠️ : Most no-PC methods have been patched on modern Samsung devices (One UI 5+ / Android 13+). Success is rare.

Even if the screen reports a total failure and the phone does not automatically reboot, leave the phone plugged into the PC for 5 minutes . Unplug it and manually restart the phone using the hardware power options. Check your software parameters—often, the CSC will have successfully shifted despite the error notice. 3. Downgrade/Flash Specific Regional Firmware via ODIN
In 90% of cases, the fix involves one of three actions: updating to the latest SAMFW Tool version (4.9+), downgrading your phone’s firmware to an older security patch, or switching from the default exploit to the MTK or manual ADB method. For the remaining 10% of users on very new devices like the Galaxy S25 series or Fold 6, you will likely need a paid hardware tool until SAMFW releases an updated exploit engine.
