I attempted a magic trick: Upgrade or Replace the Kobo's internal SD card using only the Kobo itself, no card readers, no partitioning or disk imaging on the PC.
The Magic Memory Upgrade Mod enables the Kobo to clone its internal SD card all by itself. I've only tested it with the H2O, but it should work with all readers that have at least 512MB RAM, which should include all models since Kobo Aura HD, I believe? It's not always mentioned in the specs...
Once the mod is installed, it copies the Kobo's operating system into RAM. At that point the internal card can be removed and replaced with another card of your choice. The mod detects the new card, formats it, and puts the Kobo's operating system back on it. Everything without help from the PC (no cardreader and no partitioning or disk imaging software required). Apart from installing the mod in the first place, of course.
Once the mod has done its work, the reader reboots and shows you the language selection screen. It's essentially a factory reset that also replaces your internal MicroSD card, making the full card's capacity available to you.
How to use:
( also see a video here: [deleted vidme link] )
- Backup your books and settings: All files and folders visible on the KoboEreader drive, in particular .kobo/KoboReader.sqlite (Without a backup, you will lose your reading stats).
- Make sure your reader is fully charged.
- Install this mod. (KoboRoot-MagicMemory.tgz » .kobo/KoboRoot.tgz)
- The reader shows the Updating/Restarting screen.
- The reader reboots and the screen goes blank.
~~~ OS is being loaded into RAM. This might take a while. ~~~
- You get the normal bootup progress bar and the main screen appears.
(If you don't use nickel by default, start nickel.)
- A progress bar appears.
~~~ Data is being loaded into RAM. This might take a while. ~~~
- The screen goes fully black.
---> Without turning off the reader, carefully remove the internal SD card. There is no time limit at this stage, so if you haven't opened your device yet, you may do so now. <---
- The screen goes from fully black to fully white.
---> Check that the screen is white before you put in the new internal SD card. <---
!!! Any card you put in at this point will be formatted. !!!
- A progress bar appears.
~~~ The SD card is populated with data from RAM. This might take a while. ~~~
- The reader reboots and gives you the Language Selection screen that normally appears after a factory reset.
- Restore your books and settings from the backup you made. (So your reading stats are back.)
The duration of this process heavily depends on the speed of the SD card. Actually the 4GB card that came with my H2O was the fastest card. I have several 4GB/8GB Sandisk card but they were all considerably slower than Kobo's card. (apparently I always bought the cheapest SD cards.)
If anything goes wrong in this process, the progress bar will stop moving. If that happens, take out the card, hit the reset button, put the (old) card in, hit the reset button again and it should boot up normally.
Alternative 1: Resize Partition
This alternative only resizes the data partition. Useful if you already cloned a card by other means, or if your Kobo somehow came with a larger card from the factory (which, apparently, was the case with some Kobo Glo).
The resize is done using an old version of 'parted'. The other versions of this mod don't need additional software, that's why this archive is a bit larger than the others.
Alternative 2: External SD Card
Only for devices which still have an external SD card slot, this alternative copies the internal SD card to the external SD card - including all the books and settings. The process is the same as the above (black screen: remove external SD card, white screen: insert external SD card. The card you insert will be formatted).
On reboot, the Kobo will complain about the external SD card not being a recognized format. That's normal and expected, because the first partition is EXT4 instead of FAT32. At this point you turn off the device and put the external SD card into the internal SD card slot.
All variants of this mod perform a one-time action only, during which the mod uninstalls itself regardless of success. You have to re-install in order to re-try.
This mod formats SD cards, it may brick the device or lose your data. Opening the device might void your warranty. You're expected to know how to handle sensitive electronics. Use at your own risk.
