My Arnova 7G3 recently just stopped recognising it's system partition (or something similar, I'm not sure - the top "Internal Storage" section changed to 0.0B).
To fix this, I restored nanda through nandd following the instructions found here.
All seemed to go well - my apps reappeared, and all my options were set again. However, upon trying to start some apps I was told the original install files were lost and I needed to reinstall. Curious, I checked the storage settings and noticed that the standard internal storage (nandi I believe) was no longer mounted as Internal Storage under /sdcard, but now as /sdext.
(Conversely, If I insert an SD card it mounts it as Internal Storage under /sdcard, rather than the /sdext it used to)
Is anybody able to supply a fix for this? I imagine it'd work okay with the storage mounted as external if I reinstall everything, but I'm worried about it causing issues later on whenever I install an external SD card.
Edit: Probably also of note that I just reconnected to the PC, and it's not picking up the tablet via USB any more. Works for debugging, but can't mount it as an external drive. Might be a separate issue, though.
After some experimentation, I've managed to solve this myself. It seems that some of the boot files were altered somehow, namely vold.fstab
In case anyone else has this problem, here's how I fixed it step-by-step.
- Connect ADB
- adb pull /etc/vold.fstab [local/path/vold.fstab]
- Open vold.fstab in Notepad++ (or other)
dev_mount extsd /mnt/sdcard auto /devices/virtual/block/nandi
dev_mount sdcard /mnt/extsd auto /devices/platform/sunxi-mmc.1/mmc_host /devices/platform/sunxi-mmc.0/mmc_host
dev_mount sdcard /mnt/sdcard auto /devices/virtual/block/nandi
dev_mount extsd /mnt/extsd auto /devices/platform/sunxi-mmc.1/mmc_host /devices/platform/sunxi-mmc.0/mmc_host
- adb shell mount -o rw,remount /system
- adb push [/local/path/vold.fstab] /etc/vold.fstab
- adb shell mount -o ro,remount /system
- adb reboot
