Firmware up to date, factory reset(s) done but still goes dead within a minute or so. It will occasionally let you play but not change the preset (as that makes it cuts out).

Has done it for a while but I don't use it often - any suggestions and how long is the warranty in the UK?

Hello.

I had that issue for a sometime on my code50 but now I know a bit more  about it.  For at least two years  this amp was changing preset settings why I was playing on it  At first I did not reallise  that especially on clear sound, but after some time with distorted sound  it was obvious that sound become louder and more distorted. Visually I could see that display become dim and almost always was changing from number and name  page of the preset to page with settings.  Now I can see when phone is connected settings on the app are changing as well. It is gain, volume, bass, middle   and treble  parameters which move up. Master is staying like it is. After changing preset to other one and coming back to the same preset it will stay normal for some time (few second to few minutes) and change again.

I tried to update firmware but that did not help. For some time I was suspecting power supply issue as sometimes  electricity in my place can be not up to standar , but now  I am sure that is not a case.  Any idea what cause that problem and how to fix it?

good morning I purchased a marshall code 50, I immediately updated the firmware to version 1.48, I performed all the possible procedures for connecting to the phone, when I press rev and pover it goes into pairing mode and the blue light flashes but no phone that I have tried and sees it in the devices, is there a solution for this problem?

Hello

when turning on my code 50 amp I wasn't able to get any public presets made by the community iv tried factory resetting the amp reinstalling the gate way app numerous times but when signing back in I get the same error message my amp has not been updated with the recent firmware but I'm unable to because I can't sign into my account on the gate way app any fixes

The error message says

"An SSL error has occurred and a secure connection to the server cannot be made"

Hi,

I tried to update my Code 50 firmware. Everything was ok till 100% but finally failed to complete the update.
I did every process advised to fix but I’m stuck.
I can’t reset the firmware even if I reboot.
The only message I have on the screen is on the one hand “no USB connection” or “ready to update”.

What can I do to get my amp working again?
Thanks

Best Regards,
Jérôme

My Action 2 froze in the middle of a firmware update.  Nothing works now...resetting doesn't help.  Marshall won't help without a receipt, but i got the speaker as a gift.  What else can be done?

Good time! Make tones like in digital guitar processors such as NUX, HOTONE, VALETON...

Hi guys, i tried to update firmware with chrome on my Apple computer. Your support told me to use PC. I dont have a PC!

So i went to factory reset my amp and no luck. Only message i see is "chk usb" and  no reset is possible.

I need help as i dont care anymore about firmware updates just want to play on my Amp.

Thanks

How in the world are you supposed to get this working?   there used to be a utility you could download but its gone.. I have tried 3  different computers and 3 different  cables..  same problem, doesnt detect Code  50 connected.  Come out.. updating firmware should be simple.  Please provide link to firmware update utility or better help than REBOOT computer and amp.. nothing works.

What can I do? The firmware update stopped at 97% and the Marshall Code no longer works! Unfortunately there is no correct help on the community! I've tried all of Marshall's suggestions, but Marshall Code still doesn't work! Marshall Code and Mac is not compatible. Can anyone really help? Marshall's software engineers definitely can't do it. I call that; big shit!

I tried to update software on my Code 25 with Mac. Firmware 1.48 and didn't work. "An error occurred - The update process was not completed. I tried to restart Pc, AMP, nothing. Now I can't use totally the AMP. When I turn on, CHECK USB message on the display. Please help me!!

I tried with Chrome and Opera, nothing change. 

When trying to preform first time firmware update in browser it says "CODE: Not connected", although cable is connected.

What are the items addressed in this update?

I am having problems with the new firmware on my code 25 and gateway app on an iPhone.  It used to work fine but now gateway is not connecting to the amp.

Hi, I have an issue where playing some notes in fifth octave like g5 weirdly resonates with some internals of the Amp amifying the note to unpleasant degree at the start of the note and even more couple of seconds later. Notes close to it behave normally. 

This happens on both my guitars, both through the speaker and headphones on any cranked high gain Amp. My other two amps do not exhibit the same issue as well as boss gt-1000 connected to my code with ever section of it turned off.

Please help me troubleshoot this. 

Obviously, I have updated to the latest firmware and did a factory reset after. However, neither of this helped. 

I bought the Marshall stanmore ii from Amazon, and I can connect and play music normally after I bought it.

After I updated the firmware from the APP, I found that the machine was unresponsive when I tried to restart it.

Now when I plug it in, nothing happens. 

I would like to ask if there is a way to solve the current problem. Thank you

Hello-

Bought a second-hand CODE 50 and really love its flexibility when paired with the app.

I've tried recording by mic'ing it up with a SM57  but found the cabinet/speaker to be a little rattley and couldn't determine the source.

That led me to explore USB to DAW, unfortunately my brand new, and ten year old MacBooks both do not see the amp, and I cannot update thr Firmware via browser, per the instructions.

As a last ditch effort I went 1/8th" stereo cable out to L/R RCA with 1/4" adapters to get into my DAWs LINE-INs and pan hard left and right.

Works works great, but my question is - does the CODE 50 send a stereo signal from the headphone out? -and should I be running to hard panned inputs to capitalize on a stereo image? 

Also, any remedy for connecting via USB to my MacBook to at least update the firmware? 

Thx! 

After I upgraded the firmware to the new version there was some unchosen bluetooth troubeling and now even my power-switch stopped working. 

The new presets took a while to get enjoyable, but once they  make it, they´re fabolous! 

Is there any way to get the power-switch running?

Installed the new firmware and now my Code 50 cuts out frequently and has to be restarted. It also seems to have effected the sound quality.

This needs to be fixed or post the old firmware version.

I want to roll back this new firmware. The first 10 presets are changed and I need back the Plexi and metal stuff. Why did you remove them? Is there any way to offer different firmware?
