Hi Marshall, 

Since your latest firmware update to v1.47 on 1st September and your update to the Gateway app my sounds for my settings have changed.

For example the 00 setting for JTM Chill that should be using the Marshall JTM45 2245, clean setting is now distorted and despite trying to modify it I can no longer get back the lovely clean sound it had as want to be able to use cleans, crunches and distorions for the various modeling offerings so have now lost one of the three types of pre-amps.

Can I roll back to the previous firmware v1.46 which did not have this issue or is it your Gateway update that is causing this change?

Kind regards

Mick Lawson

Ever since the last firmware update my footcontroller has stopped working. It is so frustrating not being able to use it. Needs fixed ASAP. 

As stated above, I'm trying to update my Code 25 to the newest firmware update, but no matter what I do, I can't get it to connect. I have MIDI allowed through Chrome, also tried Microsoft Edge, but both are telling me that my Code isn't connected at the bottom right.

Only thing to try next is to buy a Midi Mini USB cable to see if that fixes the problem, does anyone have any input on this?

Hey, is there like a list that shows all of the updates and what the changes were?

I just updated my Code and in the MCU it said something bout a new Codec?

After updating it was not shown anymore.

So does the Code sound better now?

Thx for helping out :)

After upgrading my Code50 this morning (forced to do it as the new Gateway app does not connect to it anymore),
the pedal acts weird.
Every time I hit one of the three switches, it seems to randomly select a Setting and ignore the Setting that I linked to it.
And with Randomly selects I mean it continues to do that every time I hit the switch..

Did I do something wrong or?

Quelqu'un pourrait il m'aider s'il vous plaît je n'arrive pas à connecter mon ampli code 50 sur l'application Marshall gateway il me met ce message: CONNECTION REJECTED You may only control amps you are already connected to for audio output.

Je précise je suis sur iPhone 13 dernière version d'iOS.  Le téléphone lui se connecte sans problème à l'ampli je peux joué de la musique mais c'est tout 

j'ai au préalablement supprimer et réinstallé l'application gateway, reset l'ampli, mis à jour le firmware de l'ampli, déconnecté l'ampli du téléphone et oublier l'appareil Bluetooth, essayer sur un autre iPhone (7)... bref je suis perdu du coup je ne peut en aucun cas faire mes préset depuis mon téléphone et c'est frustrant enfin bref si quelqu'un a une solution miracle je suis preneur et merci d'avance 👌💪

Omg my code 50 as just completely lost any sound no Bluetooth, no headphones, no amp what the flip is going on I've updated firmware hundred times reset amp hundred times and nothing dead as a door nail all lights and functions on amp work OK just no sound please please please help.

Good morning, just bought a code 25 after having updated the firmware to version 1.46 the amplifier sounds very low and distorted with a lot of background noise.... i asked the dealer the substitution but even with the new one same thing happened, already tried reset and to overwrite the firmware tried changing the usb micro b cable, and tried on two computers....

what should i do?

thank you in advance.

Hello folks, I have just bought the Marshall Code 100 which I was really excited about having read the description and watched the demo videos. The amp does sound amazing, but yesterday, on the first occasion that I actually tried the amp during a rehearsal, I was shocked to discover that when I step on the provided footswitch to change presets (like activating one with distortion or heavy delay), mid-song, the flow of the sound broke, there was a moment of silence before it switched to the next preset. I've been trying to research this on the Internet, but have only found 2 instances of it being addressed, no one talks about this in review videos or blogs. This baffles me - how is (mostly) everyone ok with this?

This effectively makes it impossible to use the built-in effects of the amp, which is exactly what its main outstanding feature is. Why have 100 presets when you can't switch mid-song? Are guitarists only supposed to use the Code family to select the main sound they want for a certain song, then keep using pedals for changes mid-song? ?

I'm extremely disappointed since the built-in effects were the main reason I went for this amp - I wanted to use this as both an amp and a multi-effect board to some extent. Is there any fix for this? A firmware update may be, or does the separately-sold Code pedal make a difference? 

Seriously considering returning it at this point. Advance thanks for the replies. 

Can I update the firmware via USB on my code 50 if I use a Mac?

I've had the Marshall Code 100 for about 4 years, never done a firmware update and am having trouble connecting the head to my pc. I'm trying through Chrome and Edge, I've downloaded the Marshall utility, started with FX/MOD/REV....nothing...no connection.

Is the ONLY way to get a firmware update through the USB/tiny old outdated plug?  I'm guessing with all the technology involved with this amp, there should be another way no?

Hi folks,

Reently got myself a CODE25, however I couldn't manage to get it connected to my phone. I assume its due to faulty bluetooth module, because when I turned on the amp, bluetooth version field is missing on the screen. The amp also did not show up on my phone although bluetooth pairing mode was activated.

I did follow the troubleshooter but it didn't help.

Updated to the latest firmware (1.46)

Anyone experiencing the same? Any suggestion how to fix this?

Hello,

I want to ask if I could get Marshall code 50's firmware source code, mainly because I want to run doom on it but also because the volume is trash. If not if it could be released as open source, and if not even that (I will totally get it) did somebody here tried to reverse enginner it?

Many Thanks

I have several custom presets in my Gateway (via my PC at my.marshall.com). I synchronized my PC with the Gateway App on my Android phone and all the new presets show up (so far, so good). The problem is that when I turn on the Code 100 amp, all of my presets (in the Gateway Library on my phone) get reset to the default presets.

If I turn off the amp and re-sync, all of my custom presets show up again. When I turn on the amp, they all get reset to default values.

I updated the firmware on my CODE 100 and tried several different startup configurations, but nothing works.

Why is the amp overwriting the presets on my Gateway App?

Hi.

I've tried uploading the firmware on my Marshall Code 25 using the Chrome, Opera and Edge latest browser versions on my Macbook pro 12.3 (Monterey) using a midi usb cable.

When doing the update the amp connects and allows me to click update... it shows the progress to 100% but then gives the error below:

"An error occurred. The update process was not completed. Please try restarting your computer/device, and then try the update process again."

I must have tried this a 100 times with no success.

Now when i resart my amp to play some tunes the display says "CHK USB" and the amp wont work.

This is all very frustrating and i hope someone can assist.

I am in the process of buying a Code 100 Head and 4x12 Cab and just visited the Marshall.com website to see that it is a discontinued item. Do I stop the purchase now as I don't want to spend the money buying something that doesn't have any firmware updates or support of any kind should something go wrong. I have read some of the issues and don't want to sit with any and have nowhere to go with the problem. I'm based in a small town in South Africa so it's not just a quick trip to the Marshall store to get it checked or repaired. Marshall Support/Code 100 Owners ... Please give me some URGENT advice? The purchase process has already started :(

This post is for all those who own a Marshall CODE of any version,
to report their failures or issues when installing the new Firmware 1.46,
since there are many problems that this has caused to users and it
is worth collecting said errors to request to Marshall the necessary
corrections in a new version.

Hi Marshall Support, 

After buying Marshall Code 25 yesterday, I feel something is wrong with it. My Marshall Code 25 suddenly muted  randomly, even sometime in the beginning I try to power on.  I already updated the latest firmware, but it still happen. 

What can I do with this situation? 

I seem to be having the same issues that a lot of people have reported, where I cannot get the Marshall Gateway app to connect to my Code 25. I've only had the amp for about a week and I cannot get the app to see it. ? 

I can connect to the amp via Bluetooth using my phone (Samsung S10, Android 11) and whilst connected, can use it as a BT speaker to play music from Spotify. However, nothing I do seems to get the app to connect to the amplifier. 

-I've updated the amp to the latest firmware using my laptop/web browser. 
-I've followed all the instructions in the Bluetooth Connectivity Troubleshooter to the letter (CODE - Gateway Bluetooth Connection Troubleshooting - my.marshall.com)

No matter what I do, or what order I install/uninstall/connect, the app will not see the amplifier. Everything works otherwise - I'm able to apply Patches from ? using a USB connection - and the amp sounds great. I'd just like to be able to control it from my phone.
