Thanks to Marshall for the latest firmware (v1.48) update and new presets. The eleven new presets are cool. Thanks again for keeping us Code amp owners in mind.

Instale el ultimo firmware y no me gusto. Se puede volver al anterior?

Hola

I just updated the firmware and gateway. The app stops on android when you are going to change a parameter within the preset that is on the screen.

It didn´t happen before. Could you fix it?

Thanks so much

Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

I commented on a post from May in which the author noted unusable AMP models and problems with the effects, Distortion and Overdrive.  The author noted this followed most recent firmware update.  I too have come to realize excessive noise with my Code 25  when using AMP models other than clean. And engaging the Distortion/ Overdrive effects models is notably noisy  with a background ticking or pulsing.  I normally use Clean amp models., so had not associated with update to 1.47, but don't recall this from previous version. 
Anyone else have this issue?  Any action to address?  Any chance a Factory reset might clear this up?  Thank you

Hi, I just received these today and the app refuses to find them. I am unable to perform and kind of hardware/factory reset and as someone in the software department has decided that the firmware can only be updated through the app this kind of begs the question - if I need to update the firmware to potentially get the app to find them then how would anyone reasonably be expected to do this?

Also how do I do the reset? I have tried the holding in of the M button and control knob for 7 seconds and nothing happens. Is this still the current method? If not is there another one?

The Gateway app on my Android phone has been repeatedly losing connetion to my CODE head in recent months, and attempts to manually reconnect have usually failed. This unreliability is completely unworkable for gigging, so today I have tried to solve the problem through a thorough update and reset ... but now I can't get the connection to work at all. I deleted the Gateway app from my phone, unpaired the phone from the head (by "forgetting" the Bluetooth pairing), and have installed all pending firmware updates. When doing those installations, I noticed that several related to improving Bluetooth operation, so I was hopeful this would solve my problems. So I've gone ahead and carried out the "First connection" instructions on the website, but these instructions have failed at a very early stage. After I press Rev and Power and get the blue flashing light, when I attempt to "Pair new device" from my phone, I get the message "No nearby Bluetooth devices were found". This connectivity problem is definitely at the Marshall end, because I have checked that my phone is able to connect with other Bluetooth devices and it is doing so fine, so the fault is not with the Bluetooth operation of my phone. It seems like there have been some known Bluetooth connectivity problems that you've tried to fix during recent firmware updates, so is this something you can advise me about and give me a fix for? I hope so - there's not much point in you having a really good product if it's unusable in practice.

Hi Everyone, I have just bought a code 100 amp. Everything seems to be working yet I have no sound.  I have updated firmware, factory reset, checked fuses and wiring all seems fine. I can hear music from my laptop very faintly but if I turn up the master swtich it disappears. The headphone jack also does nothing.

Any advice much appreciated. 

I just did the latest firmware update on my Marshall Code 50. My headphones suddenly do not work when I plugged them into the jack. They worked prior to the update. I tested them on another amp and they worked fine. Has this been a firmware problem? Any possible solutions? Thanks. 

Hi,

When will the next Code %0 FW update be available.

Will it address the common issue of the Code 50 main speaker cutting out?

Based on what others have written and use to WA the issue, it really seems to be a Firmware hiccup that causes the controller to enter a weird state.

Please comment on what Marshall is doing to resolve this issue.

Thank You and Best Regards,

TedL.

Hi team. I bought a code 50 a while back and it has been working perfectly fine. Recently however, it would start going quiet while I am playing. This all happened after the new firmware update and the amp is now unusable as it goes silent after as short as just 5 seconds from being turned on. I can get it to work after pressing the bluetooth button and then back, but 5 seconds later then it just goes quiet again. I do now know what to do, seems like a software issue.

Hi,

I've just received my Code 25 amp today. It sounds good but I cannot pair it with my iPhone

It appears as "Headphones" in the bluetooth settings. When tapping on it, my iPhone says "Pairing failed "Headphones" is not supported". 

I've tried with 4 different iPhones (all up-to-date) and got 4 times the same trouble

I've successfully updated the firmware of my amp (MCU 1.47 / BT: V3.2) but it did not fix the issue.

Can someone help ??

Thanks !

I'm running the Firmware up date  on my code 100 and it's stuck at the restarting in bootloader mode code please wait (1.5 hours). I tried canceling and now  notice an electronic hum it never had.

Please people, could you help us to developing a new firmware update to fix the DSP AMP simulations for Code 25/ Code 50?

If you could make a fast research on web, you are going to see that this is a very common issue for all Code users. Probably the last firmware updates is affecting just a part of the DSP boards, not all, but in my case and many other people, we can not use the AMP simulations anymore, and the Distortion and Overdrive FX are not ok too.

At least,  could you make the older firmware versions available for tests? I'm sure that most part of the users prefer to have the original and very nice tones than bluetooth running better, better connection with the App, or any other improvement.

Thank you, and please, consider our beg.

So, I have had this problem on my CODE 50.

I turn it on, plugged my guitar in it, everything normally, but after some seconds or minutes playing, it just get muted on! 

The funny thing is that the Bluetooth keeps working on... I tried to eliminate some bad connection but I never found one. My cable is good, my guitar is good too... I don't know, it maybe could be a board problem or a electrical/power supply fault... 

The Amp and display are up to the date, firmware 1.47.

Please any advice is welcomed 

The Gain and Mid knobs on my Code 25 are unable to reach 0 or 10 despite being turned all the way down and up; the gain's range is 3.7-8.1 and the mids are 1.9-6.1. Resets and reinstalling firmware have yielded no results.

After selecting a Preset, and after playing a song when I go back to the Gateway app I see a message saying, "Amp Disconnected, Connection with your CODE amp has been lost. Please check your amp and try to connect again." When I select "OK" it reconnects then I can select a preset. This seems like a new"bug" since the Gateway app has been updated to the current version. My iPhone is on a stand close to my CODE 50 the entire time. (about 1 or 2 feet at most).

Please advise. Thanks!

CODE 50

Hi everyone, 

I bought the new DSP module and plugged it into my Code 25. Everything seemed to be fine,

However, when I turned it on the code went into bootloader mode and said "chk usb". I inserted a cable and my PC saw it saying "connected". Still neither the marshall site not the PC application provide with possibility to update. The site shows no information and the PC app says that the last firmware version is installed and cannot reinstall it. When press reinstall button nothing happens.

I tried Mac, MS Edge and other browsers, nothing works

Any ideas?
