Fixing Odin Firmware Installation Failed at Hidden.img Issue on Samsung Galaxy Devices

13

Installing stock or official firmwares on Samsung devices is way easier that performing the same task on devices from other brands. You only have to get a utility called Odin, which has been developed by Samsung and is easily available unofficially, download the firmware file and go through a few steps to flash a firmware on any Galaxy phone or tablet.

Anyway, however simple such procedures may be, there always are the chances to get into some problem or mess. While most of the Odin flashes end up nicely with a PAAS! message, sometimes the firmware installation don’t end up as expected and fails because of some issue.

In the past, I wrote a bunch of tutorials for fixing different issues that are faced by users while trying to install a firmware on Samsung Galaxy device using Odin. Below, I’ve listed a few of them:

If you have been trying to install a firmware file on your Samsung device and the firmware installation fails because of hidden.img issue, you can use this tutorial and fix the problem.

The solution of firmware installation failure in Odin because of hidden.img is very easy and here’s how you can fix it.

Prerequisites

  • The stock Samsung firmware file with .tar.md5 extension.
  • Install a zip extractor program like 7-Zip if you don’t have it installed on your computer already.

Fixing Odin Firmware Installation Failed at Hidden.img Issue

  1. Open the folder where you have saved the firmware file. Then click the View option in Windows Explorer menu and enable File name extensions option there.installation-failed-at-hidden-img_1
  2. Now you will be able to view and edit file extensions. Right-click the firmware file and select Rename option. Now remove the .md5 extension from the file name so that it end with .tar only (see below)installation-failed-at-hidden-img_2installation-failed-at-hidden-img_3
  3. Now right-click the firmware file, highlight 7-Zip and select Extract to “firmware file name” option.hidden-img-issue-samsung-odin
  4. Since the firmware file is big, it will take a few minutes to extract.installation-failed-at-hidden-img_6
  5. After extracting the firmware, open the extracted folder and make sure that the system.img file size is not 0 KB. If that is the case, use a different Zip extractor.installation-failed-at-hidden-img_5
  6. Anyway, look for the hidden.img file in the folder and delete it.installation-failed-at-hidden-img_7
  7. Now select all files in the folder by pressing Ctrl+A keys.
  8. Right-click on the files and select 7-Zip> Add to archive… option.installation-failed-at-hidden-img_8
  9. A new window will pop up. Click the drop-down menu in front of Archive format and select tar and click OK.installation-failed-at-hidden-img_10
  10. 7-Zip will start compressing the files. Wait until the compression finishes.installation-failed-at-hidden-img_11
  11. When the compression is done, you’ll get a new file with firmware name and .tar extension. Right-click this file and add .md5 extension so that you have .tar.md5 extension.installation-failed-at-hidden-img_12
  12. Click Yes when prompted to ask if you want to save the changes made in the firmware file name.installation-failed-at-hidden-img_13
  13. You now have your firmware ready for installation.

  • Remove the .md5 extension from the firmware file and then try installing the firmware. Use Odin 3.09.

  • Rémy Ginoux

    Hi Rakesh
    I met exactly the issue you described and try to resolve here…

  • You can do 2 things:

    1. Redownload the firmware file and verify the MD5 checksum: http://www.droidviews.com/check-md5sum-of-a-file-on-windows-mac-and-linux/

    2. Enable ‘view file extension’ option in Windows explorer (see above), remove ‘md5’ extension from the firmware file and try installing it.
