No, I don't have any other mods installed.
I scanned the target micro sd card with Paragon Partition Manager and there's just one blank FAT32 Partition on it. Neither files nor filesystems.
Honestly I don't know how it has to be formated or partitioned.

I'm not familiar with Paragon Partition Manager, does it show whether it's msdos partitions or gpt/efi partitions? The latter might cause problems [GPT has a copy at the end of the medium, which wouldn't be overwritten by this mod]; most SD cards just come with msdos partitions, I haven't been able to test the GPT case yet.

If the mod worked properly it would have 3 partitions. This is the first step done by the mod after putting the new card in, if that already failed it might not have detected the card properly or there might be a compatibility issue with the card... do you have any other cards to try with? (trying with a small [1GB+] card is fine too, just to see if it doesn't work in general for you or just not with this particular card)

The screen did go black before you removed the original card, and white before putting in the new one?

I solved the problem now.
It was the microSD card's fault. I tested the writing speed and it was incredibly low (0,12 MB/s). So I bought an other card from Lexar and it actually worked!

Thank you for your response!

Wow, that's strange. Isn't this card rated for 10MB/s write or above?

Thanks for your feedback.

The external alternative of this MagicMemoryUpgradeMod would do so for you. You can download it in the first post.

On a shell you might do something like:

Code:
# insert ext. card
killall nickel sickel pickel fickel
umount /mnt/onboard /mnt/sd
mount -o remount,ro /
dd bs=1M if=/dev/mmcblk0 of=/dev/mmcblk1
sync
# eject ext. sd card
reboot
On devices without external SD card you could also grab an image of /dev/mmcblk0 over the wire.

Using my WebPortal / FileManager mod you could also download an image of /dev/mmcblk0 through your PC's webbrowser.

Hi Frostschutz,

Many thanks for fast response! and help me!

Code:
[root@(none) ~]# killall nickel sickel pickel fickel
killall: pickel: no process killed
[root@(none) ~]# umount /mnt/onboard /mnt/sd
umount: can't umount /mnt/onboard: Device or resource busy
Unfortunately onboard is busy.

this is my mount:
Code:
[root@(none) ~]# mount
rootfs on / type rootfs (rw)
/dev/root on / type ext4 (rw,noatime,nodiratime,barrier=1,data=ordered)
none on /proc type proc (rw,relatime)
none on /tmp type tmpfs (rw,relatime,size=16384k)
none on /dev type tmpfs (rw,relatime)
none on /var/lib type tmpfs (rw,relatime,size=16k)
none on /var/log type tmpfs (rw,relatime,size=16k)
none on /var/run type tmpfs (rw,relatime,size=128k)
none on /sys type sysfs (rw,relatime)
/dev/mmcblk0p3 on /mnt/onboard type vfat (rw,noatime,nodiratime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
And my blkid is:
Code:
[root@(none) ~]# blkid 
/dev/mmcblk1p1: LABEL="DG800" UUID="3600-1EFC"
/dev/mmcblk0p1: LABEL="rootfs" UUID="32eca9c7-bb88-44c9-99ee-774e3b27a7b2"
/dev/mmcblk0p2: LABEL="recoveryfs" UUID="7ffa7983-cb2a-4139-82a0-0fd1f91db09b"
/dev/mmcblk0p3: LABEL="KOBOeReader" UUID="4FB9-58CF"
"DG800" is my uSD card label.

should I kill something else or what is the problem?

Best Regards,
Robert

If you have an open book you might also kill adobehost.

Something like this might list other pid with open files on /mnt/onboard:

Code:
ls -l /proc/*/fd/* | grep onboard
Quote:
"DG800" is my uSD card label.
Note the dd command I posted above will overwrite that card entirely, destorying whatever is on it so it won't have that label anymore afterwards either. If you want the backup as a file instead of a directly usable backup card, it's different.

Thanks again.

After restart there was no runing process to stop umount so started dd.
I assume it takes few minutes to finish...

I realised, dd of with device only (without parition and filename) will wipe my sd completly

Thanks again I hope I will able to manage backup from here. (dd is bee running now...)

I will check your WebPortal / FileManager mod. to see what is it...

While you might be able to take a backup, it's useless.... There is no way to restore it to the Aura One.

Aura One does not have any internal SD card so...

It would be different if Kobo started dishing out larger storage chips (happened with some Kobo Touch? Glo? where it was 4G instead of 2G inside) without telling anyone so you could just resize the partition. But that's very unlikely to happen again.

Thanks for this awesome and smooth upgrade option. I was able to use this to swap to a 128GB Samsung EVO Select in a surprisingly short period of time.

One thing I did notice is that after it rebooted (before swapping the microSD) it prompted me for my PIN, but I only got a single character in before it started a progress bar, and I was able to perform the rest of the steps without incident and it booted after just fine.
