After many many many failed attempts to update firmware it finally showed successful on the update page but now the screen permanently shows do not switch off or usb not connected and is unusable, no buttons work ,completely frozen.

I have a Apple laptop with chrome installed.Tryed to install the latest firmware but it goes to 100% and sticks.The new amp is now useless .Please could you help.

Hey ya'll,

I have M1 Mac Mini (Also tried the same thing on my M1 Pro Macbook Pro), tried an update to the newest firmware. Didnt work from the first place, tried turning both my macs twice, didn't do anything further. (Tried every browsers - Chrome, Edge, Opera)

Now it says B0.7/M0.0/D1.2/READY and I'm just stuck with the amp that can't even produce sound because it can't do anything. Factory Reset with AMP - EXIT/STORE Method doesn't even try to respond. How do I go around it?

I've brand new Code 50 with latest firmware (1.47).

From time to time, the speakers output turns off. I do have to poweroff OR activate bluetooth detection then exit button.

Clearly, this is a Bluetooh issue - and I need a way to turn it off while playing.

Actyally, I've bought the amp and the original pedal switch because I cannot use phone bluetooth while playing.

Please, this is a MAJOR issue, I really need your help on turning bluetooth off.

I have an incomprehensible problem with the code, I try to connect to the combo via bluetooth connection, but the device is not displayed in the list of bluetooth devices, even after pressing REV + POWER the device is nowhere to be found (I checked on different smartphones) and throughout the whole time the code emits strange sounds of knocks from the speakers that are not solved in any way, I updated the firmware several times, this did not help in the end. Has anyone had the same problem, how did you solve it?

In case Marshall decides to do another round of Codes, or for people that want to buy one, here is my bottom line after dealing with this thing for a few years. I had Line 6 experience and wanted a simpler all-in-one modeling combo with a bluetooth app that could do hard rock. The Katana looked like a toy so I bought this.

PROS: Solid construction. Looks great. Good range of amps and effects. Bluetooth app is very good and can tune every parameter. Tones can be downloaded and backed up to/from Marshall site. Amp can sound very good (after a lot of tweaking). The Plexi, American OD, JTM Crunch and Acoustic amps are good. The Guv’nor, Compressor, Chorus, noise gate and all the delays and reverbs are useable. Marshall has done sufficient software updates to correct early issues (bluetooth, tones, bugs). Can be used at bedroom volume with Master on ‘1’. Optional footswitch gives good control. Documentation is good. Updater software on PC works well.

CONS: Other than those mentioned above, all the other amps and effects are bad. This includes the JCM800, JVM and Silver Jubilee. All the cabs are bad. None of the stock patches are usable. You have to make your own. There are user uploaded patches you can try but very few are usable. Learning curve is significant. The amp is too loud. When you turn up from bedroom level to louder, the sounds change and become very boomy which should not happen with a modeling amp. No effects loop. The ‘out’ is a mini USB. Connecting to a computer requires a mini USB to USB or Lightning cable, which is not included. I tried to use the USB to record to Garageband and sound came out but I couldn’t make it sound good. The footswitch also has a learning curve, and like other people I had to have mine replaced. 

ADVICE: Don’t buy it. I bought my Code 50 new from Sweetwater for $299 and now the same version of the amp is $399. If you must have a Code, get the 25 instead. It is cheaper and still absurdly loud. The higher volume available in the 50 is useless because it sounds bad. The extra hundred bucks just gets you painfully loud solid state power amp watts. 

If you do get a Code, upgrade all the firmware immediately. You need to connect to a computer to do this, but first you have to find the cable on Amazon. This is unforgivable.

BOTTOM LINE: I have spent too many hours tweaking the Code. This is what I hated about Line 6. But the Line 6 tones were superior. I never got a good JCM 800 sound out of the Code, after hundreds of hours of work. It’s only “great” amp sim, oddly, is the American OD. Marshall’s own Classic Metal patch uses this, not a “Marshall” sim! The Code is marketed as Marshall technology with amp sims created by Marshall, but it is not. Softube created the software and tones. This is not a Marshall amp. Line 6 Marshall sims are far better.

I have now bought a tube amp. I am keeping the Code because I have mastered it and can practice on it but I would not buy it again, certainly not for $399.

Is there any way to update the firmware on my code 50 without a computer as i do not own one ?

i want to update my firmware on my code 50 amp

Impossible de mettre a jour le fireware. J'ai fais toutes les modifications proposées par le site (chrome : vérification de mise à jour et modification pour acceptation midi) mais j'ai toujours le message "CODE : pas connecté. 

Comment faire cette mise à jour ?

Recently updated the firmware for my code 50 and it stopped short of complete firmware installation when I received a pop-up to restart the installation. The amp is stuck at ready to update but now the firmware won't install again. Tried a factory reset but now the amp will say USB not connected...until I reconnect....then it will read... ready for update. Which won't update anymore or resume where it left off. Can I get the original firmware or another way to factory reset? Buttons will not activate anything anymore.

I recently got a Code 50. After a few weeks of using it and learning the my.Marshall website, I realized it did not have any of the newer firmware updates. I updated it with v. 1.47 and now I do not get any guitar sound. I get sound from my phone when it's connected via bluetooth. How can I install the previous version of firmware?

I tried using the foot peddle cable to see if it is a cable issue and strange things happened. I hear some strange music broadcast. Not sure if some neighboring device connected to my amp via bluetooth. Is there any way to turn bluetooth off and on?

I tried doing the factory reset and it does not reset the firmware. Is it supposed to reset the firmware with the factory reset function?

Thanks.

UPDATE: I got this resolved. It turned out to be an issue with the guitar.

I have installed the IOS app, and I have two Marshall speakers: the Acton II, and the Stanmore II.

The Stanmore had no issues, I suspect because it does not require a firmware update (yet).  The Acton II on the other hand, will not connect without a firmware update.  Taking that route, it leads to an indefinitel hang.  It starts and never moves past the 20% mark, and it stays that way indefinitely.

I've tried power-cycling the speaker.

I've tried factory-resetting it too.

I've also tried installing the app on my Mac (rather than the iPhone), with exactly the same results.

Nothing.

Anyone else come across this?

Updates from a Marshall support call to which I have responded:

Hello,

Thanks for contacting the Marshall Support Team. 

Let's try a few steps to see if we can resolve this issue together.  

First: it is important to note that the Marshall Bluetooth app is NOT needed to pair the speaker to your phone. Please keep the app closed until you get to the very last section of the instructions below. 

(1) Perform a factory reset of the speaker:
- Press and HOLD the Source and Play/Pause button for 7-10 seconds​...DONE​
- The SOURCE LED's will all flash quickly to confirm the reset was successful...DONE
- Remove the II Bluetooth from your audio device’s Bluetooth list before pairing again...DONE

(2) Connect the speaker to your phone via Bluetooth:
- make sure the Bluetooth menu on your phone (device) is CLOSED...DONE
- set the source to Bluetooth...DONE
- push and hold in the source button until the Bluetooth LED Light is flashing...DONE
- open the Bluetooth menu on your phone (or device), find & select the speaker...DONE

(3) Attempt to update the speaker again, complete these steps in this order:
- update the app to the latest version...DONE[UpToDate]
- make sure your phone and device are next to each other...DONE, and
- make sure that the speaker is powered on and connected to your phone via Bluetooth...DONE
- attempt to complete the update again...FAILED

Let us know if this helps.

I am using Macbook Air M1 and iPad pro M1 with Acton 2

What should I do because I can't update the firmware because it hasn't been downloaded more than 50% even after an hour?

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?

I updated my firmware today and now I can't find the tuner in the new Gateway format.   Any hel?

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?
