Solve “Verification Error”

If you face this error it asks you to reset the data. Sometimes resetting the data solve the issue but sometime it doesn’t solve the problem. If resetting the device doesn’t work then follow the step below to solve :

Step 1: Download and extract the Stock ROM (Official/Original Firmware).

SamMobile may be the best choice to download stock firmware of Samsung device. Or you can go to Samsung Updates, XDA Forum or Google to find the correspondent firmware of your device.

Step 2: Download and extract Odin on you PC.

You can download Odin V3.10.7 directly from SamMobileAndroidMTK is a fine alternative, it also offers a detailed list of Odin versions and download link. Or you can always Google “Odin download”.    After downloading it on your PC, extract it to Desktop or another location you’d prefer.

Step 4: After extracting, right-click to “Open as Administrator”.

Step 5: Boot your Samsung device into Download mode.

Follow these steps to enter Download Mode/Odin Mode

  1. Power off your device
  2. Press and hold Volume Down key, Home Key and Power Key
  3. When your device vibrates, release Power key while keep holding the Volume Down key and Home key
  4. Press Volume Up key to enter Download mode, which has a green robot figure and “Downloading… Do not turn off target!!)

Step 6: Connect your device to PC.

You device should be automatically recognized by Odin. At the lower-left of Odin interface, it should show a message that says “Added!” and in the meantime you should see a light-blue box at the ID:COM section stating “COM:3” (the number depend on which USB port you have plugged the device cable and is irrelevant).

Step 7:  Click “PDA” or “AP” and select tar.md5 file that you have extracted in step 1 and then “Start”.

Whether it is “PDA” or “AP” depends on the version of Odin that you used. But the md5 file goes to either “PDA” or “AP”.


When the flashing process is done and if everything goes well, you should see a big green box saying “RESET” or “PASSED” (depends on the version of Odin is used). By now, the device should be rebooted and it is safe to remove/unplug your device.


If failed, what should you do?

Try these things first:

  • Update your device driver software to the latest.
  • Restart your computer.
  • Run Odin as Administrator.
  • Try different cable (original one or the one with better quality) and USB port (the main port recommended)
  • Re-download the firmware file, make sure it is intact and match your device model

If everything goes well you now can successfully get your android to function again and you have solved “Verification Fail” error. If this article helps you feel free to share this article with your friends.
