I report NO ISSUES with the latest Firmware 1.46 Update to my Code 50. All systems GO. - Kevin Towns 13 Mar 2022 at 02:46 PM

Hi Sebastian,

If you are having issues, we have suggest you have  the amp looked at by an engineer, a flickering screen is not a firmware issues, its more hardware which means it needs to be checked over.

It's not my personal case, my intention is to compile all user bugs of Marshall CODE due to update 1.46 in a single post, since there are many bugs about it. - Sebastián Mancipe 02 Mar 2022 at 05:03 PM


Though it's not what you want I report "no bugs" with FW1.46  - neither with my two recent 100Cs nor  with  both of my my former 50s.

I've got CODE 25 for 5 years, and I did all firmware updates - never had any problems with BT connection, Android app or other malfunctions. - Jacek Klimkiewicz 04 Mar 2022 at 02:23 PM


I have never had any bugs with the amp. The phone app has a few "quirks" but in general everything works fine.

It's not an updater issue, but .NET Framework. Try this:

1. Version 1.45 is installed on the latest amps, but is not (yet) available for download on the Internet
2. The firmware version that was previously installed on my amp was not actually 1.45 but an older version but due to a bug the 1.45 was shown on the screen. I remember reading the same thing on the forum about a previous version (somebody read screen v1.11 after installing v1.41). ?
