Kobo µSD Card Image Requests

I left the image available for anyone who has the experience and tools to use it but, IMHO, it is not for the faint of heart. So far the only two people who have tried to use the image and were able to access their internal storage, have reported that their internal storage was damaged and so the device could not be recovered.

Hi,
I finally managed to restore my Kobo N873 Libra H2O (I remember not having the SD card but the memory soldered to the motherboard) with the image provided in this threat.
I connected my Kobo to a Raspberry Pi 5, using a USB to TTL interface
Using GND, TX, and RX,
The RX from the debugger needs to be connected to the TX on the Kobo, and vice versa.
I didn't solder anything. I positioned the pins so that they made contact and then I didn't touch anything else.
And connected Kobo to the Raspberry via mini USB.

To identify the adapter I ran this command (In the Raspberry Pi OS terminal)

ls /dev/tty*

in my case it was ttyUSB0

Installed putty (In the Raspberry Pi OS terminal)

sudo apt update && sudo apt install putty -y

Once installed you can find the application in the Internet menu
To connect Putty to Kobo using the adapter I selected serial connection and entered ttyusb0 and speed 115200
If it asks for login, it means it has passed the boot phase.
So you need to turn everything off, have the serial console ready, and as soon as you press start on the Kobo, press the space bar to stop the loading.

Once I started putty I entered this command to enable storage mode (In the Putty window)

ums 0 mmc 0

To identify the correct disk.(In the Raspberry Pi OS terminal)

lsblk

In my case it was sda

Then, after copying the image to the root of the Raspberry Pi, I ran (In the Raspberry Pi OS terminal)

sudo dd if=kobo.img of=/dev/sda status=progress

and after a couple of hours, once the update was complete, I rebooted.

As soon as I restarted it asked me to update to the latest version

Ps.
As an alternative to putty, you can use minicom, which is entirely command-line-based.
To install it,

sudo apt update && sudo apt install minicom -y

To start the connection,

sudo minicom -b 115200 -o -D /dev/ttyUSB0

Once you have access to the disk you can also create an image of it

sudo dd if=/dev/sda of=kobo.img status=progress

This is pointless if you have any corrupted files.

Done!
Back to normal.
Good luck to everyone

Thanks very much for that post! It looks like it will be very helpful to the next person who wants to try recovering their Libra H2O!

Hello Browinie, very interesting.
Did you used 5V or 3.3V TTL level ?

Hi everyone,


A few days ago, I accidentally bricked my Kobo Clara HD. While trying to migrate to a new SD card, I mistakenly formatted the original card before creating a backup.

Would anyone be willing to share a working image of the original SD card with me?

I'd really appreciate your help. Thank you!Hi everyone,

Please excuse my English, as it's not my first language.
