At some point Link2SD told me that it needed to regenerate the mount script, did it and offered a fast reboot option. This caused an endless boot loop which I escaped by
- checking the SD card (partitions: fat32, ext4, swap) in gparted on a PC. It turned out, it had some severe error which could be fixed. This is probably the reason for the need to regenerate the mount script. And by
- moving the folder
dalvik-cache
on the second partition temporarily to the PC, booting the Android device, shutting it down, movingdalvik-cache
on the device again (otherwise it wouldn't break out of the boot loop)
After rebooting > 70 % of my apps were gone from the app menu. Their icons are still on the five main screens. The content of the SD card didn't change, so I believe there's high change to restore the apps by fixing Link2SD. I'd like to know how to do that.
I'm running a 4.0.4 no-name device.
