Either you got a Samsung Galaxy smartphone or tablet or both, there is a good possibility that you have used Odin. Odin is really an essential tool if you have to install a stock firmware or flash a custom recovery or Chainfire’s Auto-root package. If you need to install any file with .tar or .tar.md5 extension, you must use Odin. While in most cases, flashing a firmware, custom recovery or root package goes successful, sometimes the easy procedure does not end up as expected.

The very glimpse of the big green PASS! message on Odin puts a victorious smile on our faces but have you ever had the opportunity to encounter the red signal with FAIL! message? In some cases, the failed installation does not affect the functioning of the device, but sometimes, a bad flash either bricks the device or puts it in a state where it fails to boot normally. It all depends on what type of installation failure you have encountered in Odin.

How to Fix Odin Firmware Installation Failed at Hidden.img Issue

Today, we’ll see how we can fix the “invalid ext4 image” error  that you might encounter while flashing the stock firmware on your Samsung Galaxy device. “Invalid Ext4 Image” error” is an error that can be found while attempting to flash a firmware using Odin with a downgraded (or sometimes upgraded) bootloader to the one currently installed on a Samsung device. So, before you proceed to the actual workaround for the issue, let’s dig a little about what exactly EXT4 is!

What is EXT4?

Actually, EXT4 (fourth extended file system) is a file format for Linux that aims at extending storage limits and add other performance improvements to devices that use Linux kernel. Since Android is based on Linux, it also uses EXT4 storage infrastructure. When the Android OS was launched in 2008, it used EXT2 but Google decided to upgrade its storage system to EXT4 in 2010.

Thus, when people talk about EXT4 with reference to Android, they actually refer to create an EXT4 partition on your SD-Card. For example, if you got an SD card or device with 16GB storage capacity, you have 14GB FAT32 space and 1GB EXT4 space. (the 1GB space remains non-existent for the user). Having an EXT4 partition on the device allows you to move apps to the else non-existent EXT4 partition and thus you get more free space on the internal storage.

How to Fix Invalid Ext4 Image Error in Odin

Having been acquainted with EXT4 file system, let’s now head to our real topic. Since the “invalid ext4 image” error is closely associated with storage partitions on your device, it can be fixed by repartitioning the internal storage. The issue often pops up while flashing stock firmware on Samsung Galaxy devices that are available in various internal storage (like 8GB, 16GB, 32GB, 64GB, etc.).

Invalid-Ext4-Image-Error-in-Odin

The system partitions on Android devices are assigned depending on the internal storage and when you attempt to flash a firmware on your device, you sometimes need to provide the PIT file that tells the firmware to allocate the storage partitions according to the partition map provided by the PIT.

On non-Samsung devices, wrong partitioning sometimes results in reducing the internal storage to half. For example, if you got a phone with 32GB internal storage, it might show only 16GB space after flashing a firmware. I have encountered this issue a couple of times on my Nexus 5 and LG G2.

So, in order to solve “invalid ext4 image” issue on your Galaxy phone or tablet, you’ll need to get the PIT file (the file that determines the partition on Samsung devices) for your device. You can find the correct PIT file for your device on various forums. In case you don’t find it, you can manually pull it from your device using Heimdall tool. Make sure that the PIT file you use is exactly for the same model number and storage capacity as yours. If you have a Galaxy Note 3 SM-N9005 (32GB), for example, the PIT must be from the same model.

Flashing Stock Firmware and PIT File

As I mentioned above, repartitioning the device by telling the firmware that your device is a 16/32/64 GB variant can fix the “invalid ext4 error”. Having grabbed or extracted the correct PIT file for your device model, all you need to do is to install it along with the firmware file. The procedure is just the same as doing a normal flash with Odin, but you need to add the PIT file too.

  1. Download the firmware file you want to install.
  2. Download Odin v3.09 or v3.10 and unzip the file: Download
  3. Make sure you have installed Kies or Samsung USB drivers on your PC.
  4. Enable USB Debugging on your device by going to Settings> Developer options. In case the device is unable to boot, skip this step.
  5. Backup your data and apps and charge your phone to have at least 60% battery level.
  6. Turn off the device and boot it into the Download Mode. If your device is stuck in a boot loop, long press the Power button until it turns off, or just pull out the battery and reinsert it after 20 seconds. You can get into the Download Mode by holding the Volume Down+Home+Power keys simultaneously for 2-3 seconds. When the warning screen with a yellow triangle appears, just press the Volume Up key.
  7. Open Odin folder and launch the tool by double-clicking the executable file.
  8. Now connect your device to computer using the original USB cable that came with your device.
  9. The message box on Odin must show “Added!!” text for successful flash. If you do not see it, try to re-install the drivers, enable USB Debugging, try a different USB port and reboot the PC.
  10. Now click the PIT button and select the .pit file you downloaded.
  11. Then click the PDA/AP button on Odin and add the firmware file to this field.
  12. Since you are going to flash the PIT too, you must not forget to check/tick the Re-Partition option on Odin. Check the screenshot provided below and make sure that you have taken care of the things highlighted in red.odin-firmware-flash-pit
  13. Okay, now click the Start button in Odin. The installation procedure should go uninterrupted now.
  14. Just wait until the ID:COM port turns green with PASS! message.

Finally, your Galaxy device will automatically reboot. Just wait patiently as the first boot might take up to 3-6 minutes. In case, your device does not get past the Samsung logo even after 10 minutes, perform a data/factory reset from the stock recovery. If you don’t know how to do that, head over to the following tutorial:

    SM-J327P

  2. my sm-g530f stucks on logo i dont know the band version of my phone how can i find the right stock rom for it?

  3. Brother, you are my hero…I was tried to flash my cellphone many times and always received the message “FAIL”, buy thanks to you I got the PIT file and will flash together with the ROM file and Kablam ! I don’t receive any error message. Thanks a lot for your help.- Blessings from El Salvador.

  4. Hello, I have SM-G750H, but I sincerely can’t find a pit file
    anywhere for this one. Can I request your help in finding one?

  5. Excuse me…

  7. You have SM-J110G pit? my phone is not working, odin mode appeared. please give me pit, i need that so bad.

  8. i’ve tried all the link in 4shared to download this file but no luck instead all ads are coming up ..

  9. Thanks a bunch. Using your PIT file fixed my ext4 Fail error while flashing Samsung stock firmware on my SM-N910F. I did encounter the never-ending logo screen and then after trying to boot into Recovery got the falling down Android and the words “No Command”, but then after taking the battery out and rebooting into (stock) recovery again it worked, did a factory reset and restarted, BAM! it worked! I’m SO relieved! THANKS!

  10. Not really. But don’t think it’s the same problem discussed here. After using the PIT file I’m not getting the ext4 error. Now I keep getting mmc read errors. I can get into ODIN, install the stock firmware np, but in the end it’ll fail to boot and show that mmc read error. Hopefully its not an actual hardware fault. I’m just downloading a stock/repair firmware. See how that goes.
    Thanks so much for helping.

  11. Thank you for the article and thanks for providing the PIT file! (N910F). It did clear the ext4 error.
    Although when the phone started back up it told me the file system or something was corrupted and I had to do a reset. After I hit reset it hung on the initial Samsung Galaxy Note 4 screen.

  12. I have an Samsung Galaxy J5 (SM-J500FN) i dont finde the pit anywhere can you send me an link?

  13. Thank you very much for the answer, do I need to use a custom room from my country or I can use any room? Btw I’m from Romania

  14. Thank you very much for the quick answer, I just want to ask if GT510 actually works, I’m a little afraid to screw it up even worse.

  15. Hello, I have Tab A SM-T550, but I sincerely can’t find a pit file anywhere for this one. Can I request your help in finding one?

  16. No error occurs. Just stay stopped in “Get pit for maping”

    File analysis..
    SetupConnection..
    Initialzation..
    Set PIT file..
    DO NOT TURN OFF TARGET!!
    Get PIT for mapping..

  17. I have Galaxy Note II N7105T, 32G. All the pit files that i have tested don´t work.
    Anyone have the correct pit file?
    thanks!

  18. I tried ROM file with different versions of ODIN. All of them gave me Fail!.
    Single file didn’t worked too.
    I try the links you sent. I hope they work.
    Thanks

  19. Thanks Rakesh,
    But unfortunately for me said Fail!
    I tried some other ROM (one file and 4 files).
    The model is GT-N8000, 16GB. I bought it from Tehran at 2013 and on it’s back it say: “Made in Vietnam”.
    Do you have ROM file (4 file) for it?

    Thanks in advance

  20. Dear Rakesh,
    I have Galaxy Note 10.1, N8000, 16GB.
    I need pit file. But is’s not in your list.
    How can I find it?
    Thanks

  21. It is not SIM locked. I had 6.0.1
    I flashed an older firmware version (lollipop) and still got the same message.
    But now my phone boots normaly !

  22. Hello Rakesh
    When I follow all the steps and I flash the stock firmware and pit file I get this message: Secure check fail

    I used the pit file from your guid.

    I have a SM-G900F 16GB
    (If I dont use the pit file I get “Invalid Ext4 Image Error”)

  23. Gracias !!! Volví a Stock despues de Cyanogenmod 12.1 y me encontré con “Ext4 Image error”.

    Thank you very much! I returned after CyanogenMod 12.1 to Stock and found “Ext4 Image error”.

  24. sir I have Samsung galaxy note 10.1 gt-8010 and I am stuck on first screen (Samsung galaxy not 10.1) when I try to enter into recovery mode the android gay appears and than disappears and restart automatically and stuck on same screen (Samsung galaxy note 10.1) all day if I want to save my battery than I plug it and off it completely please help me………………………..:(

  25. Hi I’d be very grateful if you could help! I wanted to root my S5 SM-G900F (UK) & used Odin & CF-Auto-Root-klte-kltexx-smg900f.tar.md5 – It didn’t work but rebooted & froze on the Galaxy S5 screen. Then tried to flash the phone apparently with the wrong network file, then with the correct one & it boots past the S5, O2 screens then hangs on the samsung screen with the animation. I’m trying some other O2 files but pretty lost now! Only wanted to root it! 🙁
    If you have any ideas that would be great – thanks Phil

  26. Thankx Buddy….I have been stuck to this error for whole night, but then found your solution. It works 100%. Only experience I want to share is that the user needs to correctly Install the official Samsung mobile drivers then install samsung kies and DO update it from Tools/Help. This is how the PC will run ODIN properly while detecting ur device or in my case Note3 N9005.

  27. Btw the extracted filed are marked as opens with internet explorer, should i change that?

  28. Not sure about the odin screen, but i can tell you that once i extracted the frimware to .tar.md5, i try to use odin to put it in the ap box and plug my phone in, which should’ve worked but it says volume size too large, then does not complete.The firmware btw is 1.97 gb

  29. Look sir, i may be a bit late, but if you could help in any way possible, i’d be really grateful. i’d like the pit file for the GM530T1, it would help me fully restore the rom on my phone, seeing as how its soft bricked cause of me rooting it and geting blocked by the FRP. thanks.

  30. Wow. Honnestly, saved my life! Kinda pannicked when it failed and couldn’t boot. Thank you!
    Note 4, SM-N910F
    Cheers.

  31. Hi.
