MTN 6215-5910 error 04, can't upgrade firmware

[Jonass]

Hello

Have been getting for years an error04 on one off our MTN-6215-5910 devices and need to program device adress over and over. Saw there's a "recent" update due to a possbile fault that destroys memroy (finally, tried when it first arrived to contact support but they dissmissed it (out of warranty)). Been trying to update firmware but no sucess. Multi touch updater won't recognize the device is in update mode, it goes in to normal usb mode no problem. 

Do I have to recognize defeat and throw it in the bin or is there some solution still.

Hello Jonas,

have you enabled this parameter?
"Start button for firmware update"

This activate the update button on the MT screen.
You have to press and hold it until the screen turns to black.
Then, you should be able to proceed with the firmware update process

Most probably you haven't installed the driver. After installation of the update tool (you need version V2) you will find the drivers in the following folder: 

C:\Program Files (x86)\Schneider Electric\Multitouch Pro Update\MultitouchProDriver.zip\Driver

Select the folder according your Windows version (use WIN10 if higher version) and install the driver (+.exe file).

The citeria for the problem matches a 100%

Ps, it was nearly impssoible to find the updater tool. Finally found it on an old Merten site. Non of the site SE is geo forcing (so stupid) me on had it and it wasn't provided with the buletin package.

Hello Jonass

Happy to hear that the update tool is working now. 

And many thanks for the hint about the missing of the tool on website. I have informed the responsible people about this.
