CRC problem in firmware update

[NeoM]

Hello, just got a problem in the firmware update.
Every time I tried to do it via MegaDrumManagerFX it got stuck. When I try to do it via command line it displays always a CRC error, and it's impossible to get anywhere.
I use it on a system with Windows Ultimate 7 service pack1.

Any help will be welcome.

1. Please make sure you closed all other MIDI applications/utilities during the firmware upgrade.
2. Please make sure you selected correct firmware file.

[NeoM]

I did. There's no other MIDI application in the PC. Actually, I tried with all the possible ports.
I selected the firmware that is theoretically assigned to the module, i.e. megadrumSTM32d_56_20180521.bin
I also tried it with the other available files, even with those which are supposed to be for a different module, and always get the same response: CRC error.

Can you please try on another PC and then as per viewtopic.php?f=3&t=1252 instructions list what you do and what happens?

[NeoM]

I tried it on another PC and it keeps crashing, although for once it looked like it was working (but when I powered up the module afterwards it didn't switch on).
All next times it crashed again. I attach a screenprint of the cmd line.

Can you please describe what you do and what happens ( just like the instruction) when you do it. Something like.

1. I press the button LEFT (which is built-in into the left rotary encoder) and keep it pressed while powering up MegaDrum.
2. When I release the key LEFT I see:
FwSUpdaterSTM32d
StartUpdateOnPC
...
and so on.

[NeoM]

1. I press the button LEFT and keep pressed while the module powers up
2. When I release it I see:
FwSUpdaterSTM32d
StartUpdateOnPC
3. Having downloaded the updater and the firmware, I run cmd line:
mdfwupdate.exe megadrumSTM32d_56_20180521.bin
4. The rest, exactly as you can see in the screenprint. I choose the MIDI ports for MegaDrum and it starts trying to update the firmware, but every time the CRC error apears.

Can you please take screenshots of :
1. Control Panel\System and Security\System of both PCs?
2. Task Manager->Applications right after starting firmware update?

Also, do you have a powered USB hub?

[NeoM]

I have a powered USB. Otherwise, the module wouldn't have worked before...
When I connect it, it appears on the hardware list. See it yourself.
