So sorry to be a burden to the group…it seems I got over excited with my updating and probably did something stupid.

&nbsp;

I downloaded the latest firmware&nbsp; v4,086 and started up MIOS Studio 2.4.6 everything seemed as I had left it and it discovered my Midibox via my cheap Chinese style usb to midi in/out cable no problem.

&nbsp;

here is where I THINK I went wrong… I had the options of folders

&nbsp;

MBHP\_CORE\_LPC17

MBHP\_CORE\_STM32

MBHP\_CORE\_STM32F4

&nbsp;

I chose STM32F4 (I now suspect wrongly)

&nbsp;

MIOS let me upload just fine and I did get the …success…message at the end of the upload.

&nbsp;

I then turned my MIDIBOX SEQ V4 off and on again…only to be greeted with black squares on the display…nothing else.

&nbsp;

no amount of waiting around will yield it doing anything else and now it won’t seem to connect via my USB to din cable at all…

&nbsp;

I took a look through the trouble shooting guide but I am not seeing my usage case.

&nbsp;

please help if you can, I am really worried I have killed my box.

&nbsp;

thanks

&nbsp;

Phill

Which core board do you have? Try flashing the bootloader again like when you first installed it and then uploading the app that matches your core.

Sorry everyone… I got this solved now…

&nbsp;

it seems that A . I did upload the wrong file, I needed the F1 version not the F4

&nbsp;

but the compound problem I was seeing was result of my generic midi cable freaking out and killing its own drivers.

&nbsp;

in the end I installed some EMU ones and now everything came back to life and I was able to contact the core by a power cycle.

&nbsp;

thanks for your help ,
