Hi,
I'm facing the same issue. But in my case, I pretty much know what has happened.
Please let me explain in detail:
- I wasn't able to move my apps to SD, so I surfed and found that it can be done by partitioning the SD card using "Mini Tool partition wizard", which I did. Created 2 partitions, both primary; one as a FAT and another EXT2.
- Then I used Link2SD to move the apps, but it didn't work.
- When I tried downloading a picture from my whatsapp, I got this message.
- Now my phone does not show up on my PC as a removable storage, neither it is detected by Mini tool.
I have a HDC(It's a chinese brand) 6 plus(iphone copy) which runs Android 4.2 or 4.4 not sure as it does not display it anywhere.
PLUS I do not have any knowledge about android, and that's why I'm in this spot. :'(
