2. Opened the back cover of Kobo and replaced the card, powered on the device which asked for setup through Wifi or PC.
3. Instead of choosing the Wifi, I selected setup through PC, and connected the USB.
4. The device demanded a connection to Kobo desktop, which I ignored, and as could see the internal SD card through windows explorer now, I copied the firmware files of FW 3.19.5761 to .kobo folder, disconnected and unplugged the USB cable. The device started setup.
5. After the setup, the device again asked for a Wifi or connection to Kobo desktop. I reconnected the USB and copied the patch file KoboRoot.tgz 'Block WiFi firmware upgrade' enabled in the .kobo folder, and disconnected the USB.
6. After a few minutes, the setup was completed and asked again for Wifi. This time I connected to Wifi and after initial logins, the device prompted an 'upto date FW' status, and came back to life. 
I'm grateful to all you guys!
Now I'm only wondering on the academic question, as to why the device became non-connectable through USB in the latest FW? Perhaps some strage reason, I guess.
Yes, I got a Charge/Connect prompt. I use Windows 10 laptop duly updated. After connecting through USB, the Kobo prompted 'Connected and charging'. It did charge, but I could not anything connected in Windows explorer via USB. So you can't modify the FW or read/write anything on it.
After the downgrade, everything is back to normal. |
Hey there! I have the exact same problem with Kobo GLO, but it doesn't seems to work.
I followed @DNSB steps to downgrade, putting the files directly on the sdcard using my phone to access it (because USB doesnt recognise the Kobo). Downgrade went fine but after that when I choose connect to laptop instead of setup using wifi, still the Kobo Glo wouldn't be recognised by Windows 10/7 on three laptops. If I choose setup using wifi it automaticaly upgrades to the latest version again.
Connecting to the pc and charging is fine from the Kobo side. I flushed the usb descriptor fails using USBDeview before that, but still doens't work.
I would like to ask for that stock image file so I could try to format the sdcard and follow exactly drdj steps. And ofcourse if you have some opinions on wtf is happening
I would be very grateful
Thanks alot in advance.
