Then you need another program that will transfer and install the RGN file to the Zumo via the USB cable before it boots up (or tries to) You need a program to convert a GCD file into an RGN file. Once you know what to look for, this stuff is easy to find.įirst, have you tried removing the battery and leaving it for a short while ?Īnd, if the Zumo is fully turned off, will the Zumo enter transfer mode when you plug in the usb cable so that you can see the contents on your PC? In which case I can send some instructions that I obtained from a very knowledgeable chap on a German website. I don't know what that is for the 390, but I could guess that it is the same as the 590. The firmware is installed before boot-up, so it requires a computer, a program and a special sequence to do it. I did it the other day to get back to the 590.Īny idea how I can get it onto the 395 as it won't connect to my computer as it won't boot up. I am speaking from my experience of using 590 and 595 software on my 590 machine. Please note that I have never done this particular task, nor have I had a 39x in my hand. Sorry - I realise that you cannot do this on your own Zumo, but if you know someone who has the same model, that is how they can get you the software. Once you have that you can create an RGN file and go through the procedure to restore the operating system In configuration and settings, select MTP settings.Ĭonnect a USB cable and the Zumo should show up on your computer as a couple of drive letters, and you should be able to see.
To get to this, you have to tap the speed button bottom left of the map screen, then hold in the circular speedo - top centre - for 10 seconds. To see it you have to put your device into Mass Storage Mode in the MTP settings.

There may be such a menu on the 590 and 39x Zumos, but I don't know how to access those.Īnyway - back to the. The XT has a boot menu that you can access to restore the previous operating system - but I've only managed to get it to restore the current one. It is quite possible that you have the latest GCD file on your Zumo itself.
