“Firmware upgrade encountered an issue” – Got This Error While Installing Firmware? Here’s the Solution!


Most Android users refrain from gettings involved with stuff like rooting and flashing ROMs simply because they are afraid of getting their phone or tablet bricked while trying to do so. I think it is a wise decision not to play with things one is not familiar with. I still remember how my hands quivered and heart bounced while rooting my first Android phone, the Galaxy S. Those terrible moments when every step to root the phone made me believe that it would be bricked, still thrill me.

Using your phone the gentlemanly way without ever dreaming of rooting or installing a third-party ROM might be justified to a certain extent. However, the question still remains— is your device safe if you depend solely on official updates sent from your phone’s manufacturer? Custom development activities might lower the chances of your device getting into trouble, but disdaining them does not guarantee that it will be safe against bricking, or rather soft-bricking! Remember, keeping to the right side of the lane does not guarantee your safety!

Even  installing the official firmware using Odin or receiving latest updates via Kies or OTA on your Samsung Galaxy device might get you into panicking situation. Personally, I know about hundred cases at least where people, while attempting to install firmware via Odin or getting OTA update, ended up with the following message on their Galaxy phone or tablet’s screen:

Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.

Some possible reasons for this error message might be:

  • USB Debugging was not enabled before installing firmware via Odin
  • USB Drivers not installed properly
  • Device was disconnected while the firmware upgrade was in progress
  • Any reason that hindered software installation

Whatever reason might be responsible for the firmware upgrade issue, the outcome is certainly not pleasant. The most popular solutions used by people for solving the issue after facing that screen are entering the device into Download Mode and install the firmware again, and booting the device into Recovery mode and wiping data/factory reset. Unfortunately, both these remedies do not help in most cases. If you are viewing this page, I assume you have a device suffering this issue, or you someone who wants to keep himself updated with solution for such problems.


Please be warned that following the procedure given below will wipe all data stored  on the internal storage of your device and installed apps.

How to Fix the Issue:

To get out of that error screen and get your device into normal condition, you need to do the following things:

  1. Download and install Samsung Kies on your computer if you do not have it already installed on it.
  2. Note down your phone’s Serial number somewhere. You can find it under the battery of your device or the box your brand new device came with.
  3. Launch Kies and click Tools > Firmware Upgrade and Initialization
  4. Connect your device to computer using USB cable.
  5. Enter your device model name in all CAPS (GT-I9500, for example) and click on OK.
  6. Then you will be asked to enter the Serial Number of your device.
  7. Once again, select OK on the next screen.
  8. Doing this will force Kies to download the require firmware update files for your device.
  9. Respond and confirm all securities warnings to clear the way for emergency firmware installation and then select Start Upgrade.samsung-firmware-restore
  10. Kies will now start downloading firmware files and the process might take several minutes depending or data connection speed.
  11. When it is finished, new firmware will be installed on your device and you will see a screen like this:samsung-firmware-restore-complete
  12. Click on OK and disconnect the cable.
  13. Reboot your device and done!

Your Galaxy phone or tablet should not boot normally and then you will feel a great sense of relief. Enjoy and cheers!

    Kies says that It says that it cannot connect, I cant find the right code for odin. Ive tried idk how many. I cant get back to reboot scren. The only two things that I can get are download screen and the firmware encountered an issue screen I have even tried to manually enter my sn and model number into kies manually but since my tablet is dead and will not charge anymore, this way did not work either. I am this close to smashing it with a hammer, but i thought i would ask first…. CAN ANYONE HELP ME PLEASE!!!! Its not just a tablet to me. Im a full time student and I take between semester courses online, and i do not have money to buy another one. Mine is a samsung galaxy 8.0. I have not been able to find anything for odin that is for jellybean, so idk if that is my problem. Another issue is that on the inside of my it says GT-n5100, but when i put that into kies it says that it does not match my sn; however, when i put GT-n5110, it tries to upgrade, ,but says it cant because the pc does not recognize my device because its dead i guess. Also, when i try odin, on the download screen it also says GT-N5110 sometimes. I do not know what to do besides get out the hammer and make myself feel a little better.

  • Alex

    I was unbrick my phone ) with “odin3 v3.07” and “firmware” Thank you very much !!! s4 GT-l9505

  • Gary

    Kies said this model is not supported…please help..!

  • The latest version for Samsung devices is Android lollipop (5.0 and above) but your AT&T Galaxy Note is quite an old device and the latest version released for it is JellyBean (4.1.2).

  • Thanks a lot for the reply! Turns out, that it had updated firmware I think.

    I tried a different cord, which took me a while to find, and suddenly it connected. I put Kies back on and it worked like a charm and said no updates needed.

    But, it’s got 4.1.2 or something on it, isn’t the current 5.1 or so?

    I’m pretty savvy with the Mac, if you ever need any help. This is an old thread so not too worried, email me at theboardrid3r@gmail.com if I can ever help 😉

  • Hi, I just got my first MacBook Pro and am still trying it. Did you try flashing the stock firmware using Heimdall?

  • Hi Rakesh, I hope that you are still around and this will reach you.

    My daughter was given an hand me down SGH-i717 from my step-father and she wants to sync it with her iTunes and be able to take video on it and upload it to her Macbook.

    We went through this before, and it updated and worked fine. Although the update took a while. It went through the same:

    Switch to Recovery Mode
    Power Volume Down, then Up
    And Download Begins, and continues….and continues…and there’s no updating of any kind to let me know it’s process, or if it’s even still underway.

    It’s now been about 10 hours. And still just “downloading.”

    Any help? I appreciate it. Using updated version of Kies as of yesterday, running Mac with Yosemite updated.

    how long does it take to download the firmware upgrade ?

    Im using a samsung s3 SGH-I747M now im following the steps that you say…

    the download is taking too long in my calculation it may take 8hours to finish the download..

  • The key combo for recovery mode is volume up+home+power.

Then tried to flash android 4.3 and for first try I failed but on second try it worked. But then Rakesh thanks for immediate response.
