But, I should have checked myself. I had my Glo apart a little while ago and took a copy of the recoveryfs. The rcS script is run to do the recovery. The lines needed are: Code:
mount /dev/mmcblk0p3 /mnt/user echo 3 > /proc/sys/vm/drop_caches; sleep 2 [ -e /mnt/user/.kobo/KoboRecovery.tgz ] && ( zcat /mnt/user/.kobo/KoboRecovery.tgz > /dev/null && tar zvxf /mnt/user/.kobo/KoboRecovery.tgz -C /upgrade && rm -rf /mnt/user/.kobo/KoboRecovery.tgz ) umount /mnt/user && sync && sync /etc/init.d/upgrade-generic.sh $UBOOT TOTALLY_NOT_USED /upgrade/$PLATFORM/uImage mmcblk0 echo 3 > /proc/sys/vm/drop_caches; sleep 2 mkfs.ext4 -L rootfs -m 0 /dev/mmcblk0p1 && sync && sync mkfs.vfat -n KOBOeReader /dev/mmcblk0p3 && sync && sync mount -o norelatime,noatime,nodiratime /dev/mmcblk0p1 /mnt/root echo 3 > /proc/sys/vm/drop_caches; sleep 2 ( zcat /upgrade/fs.tgz > /dev/null && tar zvxf /upgrade/fs.tgz -C /mnt/root) || reboot umount /mnt/root && sync && sync An interesting thing in this code is that Kobo have a mechanism to change factory reset firmware. |

Some Kobos come from the factory with a 4GB card, but they only use the same size partition as the ones with 2GB cards, so it can't be right that the partition is resized to fit the card automatically by a factory reset. Also it would be a bad idea to do that, since the reason for using a smaller partition might be to avoid media faults located beyond the partition.

Ahh, it ate my last post apparently!
Regardless, I just went through a factory reset to satisfy everyones curiosity, myself included. It worked fine Did the upgrade stage over wifi on-device. Once everything was setup, I checked out the Device information. It showed 29998MB total capacity, whereas it showed 29984 before the factory reset. Just finished syncing everything and finding my place in my book. (if anyone is curious, I only have 172 epubs on my device with jpg covers. It's only 343 MB of disc space ) Everything appears A-OK! Back to reading the Foundation series by Isaac Asimov! Will for certain post my guide with pictures this weekend. Pictures are already taken and most of the post is written. Just need to crop pictures and finish the post. Will do tomorrow after work most certainly |

Or perhaps upon resizing the partition the first time I altered the partition table permanently in a way that kobo can use later? Like the Kobo perhaps can't format a card fully, but can alter what is already there? Or that it can only alter the file table, but not the partition table? I don't fully know what I'm talking about clearly, but that seems like it COULD be right ;-) So if you don't resize the partition after cloning the microsd card to the bigger card, will a factory reset still work to show the full drive? I, for one, am not curious enough to open my device right now to find out. Last edited by Gergith; 03-23-2013 at 12:53 AM. |

Why would you void your warranty and risk bricking your device if you don't need/want the benefit?
If you don't need the extra memory for one reason or another and weren't dreaming of this already, this probably isn't for you. It involves potentially breaking your case getting it open, potentially bricking your device and for certain it voids your warranty, but I don't know if they will know you've done it if you swap the 2 gig card back in. |

I think you are right about this. But I feel that it has some access because the book partition DID change size when I did the factory reset. It was upped by about 10 mb. out of curiosity, i think I might bite the bullet and open my kobo AGAIN. This time I'll get a 3rd sd card, clone the first one onto it (4gig or bigger), but I WON'T resize the partition. Then I'll throw it back into my kobo (with the 2 gig partition on a bigger card). THEN I'll do a factory reset. THEN I'll check the memory... In fact... I think I might do all that tonight! EDIT: INTERESTING! So I just cracked 'er open and did the following: dumped the 2 gig cloned contents to an 8 gig sd card, WITHOUT resizing the partition. First book, works great, all my books from my dump are there. BUT... The HD size in device info is reading 1361 MB total. Will report/edit back with what happens AFTER a factory reset. EDIT 2: That solves it! Still 1361 MB total after factory reset. The resizing the partition/editing the partition table is something that's required for the Kobo, as it can't do it itself clearly. That's why the 4gig Kobo's only see 2gig. EDIT 3: I've finally posted my guide: https://www.mobileread.com/forums/sho....php?p=2462847 Last edited by Gergith; 03-24-2013 at 06:33 PM. Reason: Reporting backing awesome information! |
