Then, I popped the new microSD card in and powered on but it gave me a critical error and asked to do factory reset. I let it do its things and it successfully booted up, but it was back on v2.* !!!!! It's weird, why is that?! Do Kobo store their firmware somewhere else other than the microSD card?!!!!!!!!

Also, why didn't it just boot up fine? Should I not trust my dd-image and delete it and do imaging again? (dd was done successfully - it reported success)
I have to ask, what did you expect a factory reset to do? It completely resets the device to out of the factory state. The factory firmware is on the card in the restorefs partition. The factory reset formats the rootfs and the data partitions. Then it installs the uboot and kernel and unpacks the firmware.

Apart from some errors after installing the new card, everything worked properly. And plenty of people have had this sort of problem. I usually recommend a factory reset after replacing the internal SD card or restoring an image to one. It shouldn't need it, but it seems to.

If you want to get the device to the same state as on the other card, install the desired firmware. Then, take a copy everything on the data partition of the original card and copy it to the device.
