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

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 am interested in buying a MARSHALL CODE 25, but I would need to use the line output (to connect to a mixer or another amplifier), I know I can use the headphone output, but how can I use the headphone output? without disconnecting the speaker from the amp? Is there any way to achieve it?

The first time I turned on the amp and plugged in, there was a very loud screeching noise from the amp. I had to turn it off immediately. Any idea why that haappened?

Hi there ,
I recently bought a DSL1CR and see that the one speaker output states 1x16 ohms. 
I am aware it can be run without a speaker for silent listening through the emulated output. 
Can I connect my 8 ohm 1923 external 2 -12 cabinet to the DSL1's 16 ohm speaker output and run it safely? 
Thanks,
Russ

new purchase. I have a custom Eddie Van Halen replica orginal. Excact copy of the famous Frankie. 

I have spent time on the app and making adjustments however I dont get the sound i was hope for. Perhaps I need to add an FX ex Boss ME-50. To get the sound i am looking for.  ACDC / Kiss / VH. all i get is a little louder version of my guitar. I have watched many videos on line and they change the setting and get classic rock sounds. Like a Gibson or whatever. Classic rocks sounds.  I have tried many VH and ACDC pre programmed set ups and still not he tone i am looking for. What am i missing?

Thanks 

Hello,

I am struggling to connect my newly bought acton 3 speakers to play as stereo, I bought them because I should be able to connect them together, but I am afraid I will need to return them. I tried everything from the Marshall bluetooth app, but it seems that it has some update, so tips from acton 2 don't work anymore. The app doesn't even show stereo mode anymore. Is there any manual which could help me? My last option here, before I will be force to return the speakers. Thanks a lot for any tips!

I'm not very good at building effects. Can anyone build a preset for AIC Nutshell?

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.

When switching between presets, factory made and made by others - in the app the sound goes from low medium to max, up and down.. 

I use my amp on low in our living room, and its bad for my kids.. scary.

Also alot of fizz crackling when turning the master knob.  Common issue? Is there a fix? Sound jumping up and down.

When the sound is super loud i just touch the volume knob and it goes down in volume to where the volume knob actually is 

I purchased my DSL40CR in Sept 2020. Its never left my bedroom, never been played particularly loud and (unfortunately) I have not had a lot of time to use it.  The presence and resonance originally worked when I received the amp but now turning either of these two knobs has no effect.

Also there has always been an occasional, infrequent, weak 'crackle' noise.  Is this a tube problem or is this normal for this amp?

Is there an 'easy' fix, like swapping tubes?  Is that something I can do myself?

Please let me know what my options are.

Thanks,

Dean

I was playing guitar and tried changing the volume on my amp and once I did the sound completely went out. I can't even play sound connected via Bluetooth on my phone. I don't hear sound either when I connect headphones to my amp. In addition to this, I connected my amp to my laptop and recorded some sound to try and figure out the problem, and GarageBand picked up what I was playing. This problem has happened to me in the past but after I wait for a little the sound seems to come back, but this time I've waited over a week and my amp still isn't working.  Any tips? 

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?

my code 25 is frozen, nothing is working. The display shows marshall - MCU: 1,47

Connection to the pc is working, update is starting, and then please wait restarting code.

Nothing more. The code 25 is not restarting. Power off and on is not the solution

What can I do?

I want to check if my marshall major IV are legit
My serial number is 73400553L23295H0052782

hwo do I get music thru my amp/app/gateway ?

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.

Hi, does code 25 works with Tonebridge app on Android, connected by irig 2?
