Firmware update cannot be done with a mobile device (tablet or phone). You’ll nee a PC or Mac computer to update to launch the firmware update tool.

Information message

Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware.
In other terms, the firmware is the software installed in your amp. It is used to operate your amp and communicate with the Spark app

Firmware updates will be less frequent than App updates. There is usually no need to update your amp firmware unless you have some issues or if a new Firmware introduces new features.

In case you’ve updated your Spark App (or it has been updated automatically by your mobile device, you might get prompted to upgrade the firmware of your amp. Especially if you want to use the new amps and effects released regularly by Positive Grid (July 2021 Gear Drop, Experience Jimi Hendrix™ pack, etc.)

    You morons bricked my amp by forcing me into this update. I followed every step listed above to the letter and was told the firmware update was successful. I ejected, unplugged and as soon as I went to play the amp, there was no sound and just the 5 blinking lights on the top. I cannot factory reset, I can’t get the firmware updater to recognize my amp, and nothing helps.

    Great work.

    1. Please keep your insults for yourself! This website is not ran by Positive Grid!
      This issue you’re facing is known by them and can happen in some cases.
      I suggest you to log a ticket on their support page and they will send you a new updater tool.
      Your amp is not bricked and can be fixed.
      Thank you

        With all due respect, if this happened a year ago, why didn’t they replace the tool and software by now? I just bought the amp, and to be able to use the package I bought with it, I needed to update the firmware. I followed all steps, and my amp is bricked. Good job Positive Grid, good job!!

        1. I can understand your frustration here.
          So far, no new firmware updater has been released. I suppose Positive Grid hasn’t found the exact issue yet.
          It seems to impact users randomly. Now, you need to know that this can be fixed. You should contact them directly through their website and log a support ticket

    With every firmware update comes another set of issues. I have never updated my spark without it bricking.

    Hi, I have the same issue. If the problem is with the new firmware, is there a chance to revert back to the previous firmware ? Well, I prefer the amp rather working than having it with new features but not working at all.

    my spark amp has frozen on my i pad even if i delete app and re install it , once i go to select a new pedal or amp it freezes… it worked last night… why? This said I can’t download new firmware??

    1. Try to close all other opened app on your ipad and try relaunching the Spark app. See if it is more stable.
      About the firmware download, which link do you use ?

    I downloaded the v1.6.5.160 firmware updater and the application won’t run on my PC.
    The error message is:

    “Windows cannot access the specified device, path, or file. You may not have appropriate permission to access the item.”

    I am running the .exe as administrator. The previous updater loads and connects just fine.

    Any clues?

    I downloaded the v1.6.5.160 firmware and updated. bu Spark App on iphone can’t find spark device. But if i down grade to v1.5.4.102 it use normally. please help.

      1. Evert

        I had the same issue after updating the firmware to 1.6.5 – factory resetting the amp solved it for me.

    I’m download 1.2.3.37 Firmware at this precise moment. It seems its taking for, I have a good internet connection. What’ the average time of this download?

  8. Joe Delgado

    Correction… I’m downloading 1.2.3.37 Firmware at this precise moment. It seems its taking forever, more than 20 minutes now. I have a good internet connection. What’ the average time of this download?

    1. File is a 5.27 Mb so it shouldn’t take long to dowlonad. Maybre try later.
      Also please note that v1.2.3.37 is not the latest version of the firmware.

    Just learned of firmware update, but don’t own a laptop, only an iPad. I’m not buying a laptop just to update my Spark, and I don’t know anyone who would be crazy enough to allow downloading all this foreign software just to do me a favor. So the question is this, are there service centers like Guitar Center who would update the firmware for me?

    1. Hi Remy,
      Unfortunately you need a computer to perform the update.
      I can see Guitar Center is selling the Spark. You can ask them if they can help you on this, otherwise I’m affraid but you’ll have to find someone willing to help you with his computer.
      If you’re a member of the Spark Amp Lovers group on Facebook, you can also ask for someone living near your place to help you on his
      Good luck
