I have had my code 25 for about 6 months and for a while now, everytime I connect my phone and edit in the gateway app the preset freezes and I cannot change anything or change the preset. On the phone it says I am changing but there is no actual changes happening. On the little orange screen on the actual amp it stays on that preset even if I twist the knob to change preset but can still play and change volume.
TodayI was getting sick of it and looked up if there are updates for the amp and there are, which I then went and installed the latest firmware update. But now when I turn on the amp it shows that it's on and shows the preset but stays frozen and will not play sound at all. Is the amp done or can it be fixed?
I notice latest firmware update v 1.44 july 2019, improves master volume control, it doesnt spike like it used to, can someone confirm this, what other changes are there ?besides bluetooth improvement also
After installing the latest Firmware update my Marhsall code 100 will not respond. The screen on the amp says USB not connected and I cannot do anything. I have tried a factory reset but that not working either. Help.
My footswitch stopped responding under the following scenario.
Marshall Code 50
Four button footswitch
Macbook pro connected via USB
Sound output set to Marshall Code
Playing Youtube videos through the amp and playing along
After a while, the footswitch stopped responding. I couldn't change banks or position within a bank.
Unplugging the USB cable seemed to get things going but footswitch stopped responding again shortly after.
Turning the amp off an on again resolved the issue.
It seems that all of us code owners has the same problem with the master volume, it's a double potentiometer vertically soldered to the board. I've measured my master vol pot, both pot vipers seems to miss contact from time to time when you turn the knob. So thats means to me a broken potentiometer. The surface inside the pot where the viper travels is partly broken. I noticed that the pot does not have anything to do with any software or firmware, so no firmware update will help here. So my question is where to buy a new master volume potentiometer for marshall code 50. Best regards keep up the good work.
if i use a clean preset of the marshall code 100H i got issues with crackling sounds. Even after turning it off and on. Its extremly annoying and it destroyes all that i record into my DAW. With this crackling sounds this Device is absolutly useless!! I've also updated to the latest Firmware version but nothing changed!
How can I update firmware when I don't have USB port on my Marshall speaker
Trying to update my Code 50 to the new firmware but it says "Not Connected" to the computer. I've tried everything that is on the troubleshooting page, I have an Mac pro and tried with both Crome and Opera. Last time I updated it was not any problems.
I have following versions on the amp (see this when I'm starting the amp in the bootloader mode)
Do you have any more tips on how to update the firmware to the new?
I just notices this now. Im using a code 25. I have updated the firmware of the amp to 1.44. I also have updated the gateway 1.5.5. May phone connecting to the amp. But the gateway app is not connecting to the amp. Im using a galaxy note 9.
Any help please.
I just bought a CODE 100 combo. Bluetooth audio is pairing just fine but the app never finds or connects to my CODE!
I tried everything, i even uninstalled the app rebooted the phone and started from scratch following your guide but still no luck.
Galaxy s9+ up to date CODE firmware 1.44 and gateway app 1.5.5
Fix this please
Since updating Code 25 to firmware 1.44, the bootup time is now very slow and can take up to 20 sec before being able to play a sound from the amp.
Do you experience the same latency?
Any chance of a fix or a possible downgrade ?
I know that turning a "TUBE" amp on without a speaker load on the output will damage the amp.
(the no-load condition will cause the output voltage to increase until the output tubes burn out, which can then lead to other component damage)
Is this also true for a CODE 100 amp? Is there a risk of damage to the output section, with turning the unit on without a speaker cab load connected?
Would it be safe to operate the amp with just headphones connected instead of a speaker cab?
Would it be safe to operate the amp without either a speaker cab or headphones connected?
I ask because my computer (which is a desktop) is in a different location in my house than my amp.
Doing firmware updates or testing out patches requires either moving my computer or my amp, both of which are very inconvenient.
It would be much easier if all I had to move was the head.
Dear Marshall Team,
It took some time, almost a year, but finally we got the long awaited update of the firmware to fix the painful Bluetooth issue on CODEs. I installed it a few days ago (which was a bit of an issue as reported in another of my posts but finally succeeded) and now CODE does what it is supposed to do. BT comes on and connects as it should every time I turn on the amp and start Gateway on my Ipad/Iphone.
I'm very happy that you could fix the problem and I encourage all brothers and sisters in pain to upgrade the firmware asap if they haven't done already.
In the light of this fix I think we, the community, may also forgive you that for months you told us that it is not a firmware issue ;-)
So far I also think that the BT connection is more stable than it used to be.
Now I can enjoy again my little CODE 25.
Thanks, Alex F.
I cannot install the new Firmware on my Code 25.
Amp Display Shows „Ready“
Marshall Firmware Update Utility says:
„the code Firmware is being updated - please wait“
on the bottom it says
Updating MCU Firmware...
but nothing - nothing happens. No Firmware Update....
anybody having the same problem? Please help!
Best Rgds, Alex
Got it to work by using Microsoft Edge Browser and the the Firmware Update tool. (Windows 10)
Google Chrome did not work, and update tool in Coogle Chrome also didn't work.
Anyway at the end iI could update and I'm happy now because the Bluetooth Problem is really fixed.
Will a firmware update get rid of the hum associated with the Code amps?
I have the Code 100 combo.
I just bought a Marshall Code100C from the Sweetwater sale.
Anyways I have 2 older Amdroid phone and NONE can get the Code Gateway App.
But my Newest LG Android phone can download the Marshall Gateway App and install it.
Problem is when I turn on the Code 100C and Turn on The Gateway App on my Android phone
it does NOT find the Marshall 100C and I downloaded the Newest Firmware for the Marshall 100C.
What can be my problem?.Thanks allllll....JT
Now that the firmware-update finally was launched ... isn‘t there a Gateway-Update necessary? We still have version 1.4.1 in the App-Store, and it‘s about 2 years old.
I just got this head recently and installed the latest firmware update the other night (6/20/2019). When I try to connect my IPad through the My Marshall app it seems to be a hit or miss proposition but more miss than hit. In my settings on the IPad it shows me as connected, and the blue light on the head goes from flashing to solid. On the app, it shows the head detected but when I press on that I get a "Connection Rejected" (You may only control amps you are already connected to for audio output) and there's no control over the head from the app. Now several other times it syncs right up. I'm at a loss though. Am I doing something wrong maybe in the sequence (operator error) or is there an issue somewhere else. The manual doesn't really reference Bluetooth that well. I'm not bluetooth savy becuase I rarely use it except for my phone in the car and connection there is automatic after I initially set it up.
So is it me? Is it the gateway software? Is it the head?? Help please?
It took more than a year, but still!
Finally the annoying Bluetooth problem is fixed!
The amp turns on Bluetooth after power on, reconnects to the smartphone automatically without manual pairing and the application works fine (there's some problem with application scaling on LG G7 due to screen resolution, but I can live with that).
Thank you for this update, Marshall!
Even if the process was soooo slow that the 1-year warranty ended, it's good to know that you didn't abandon this product :)
Honestly I thought that we won't get any updates and I was surprised to see the Gateway application update and checked the forum just in case.
After the last update my amplifier knocks every 3 sec, when I turn on the bluetoof stops. How to restore the earlier version of the firmware, I will add that the connection bluetoof does not work the amplifier is just not visible to other devices, please help.
