As far as the backup, put it on the phone and run it. An apk is actually an installer for the app it's an apk of.

The SD card? Did you partition it on the phone? Did you format the FAT32 partition on the phone. Sometimes, doing these things on a computer gives the phone a card it won't use.

Have you put the card into a computer? Did you see the FAT32 partition? If not, I'd suspect a bad card. Do you have access to Linux (even a live CD)? Run Linux and see what the card looks like (if it looks like anything at all). If Linux will mount it, GPartEd should give you a working card or a useful error message.

 

You formatted it to ext4 which I believe is what this phone uses for its primary system partition. This is why most links2sd guides recommend ext2. Reformat it to fat32 and ext2 then give it a try it works perfect for me. But I used a computer and mini partition wizard to format it.

As for the really big games, use GL to SD from the Play store. That will symbolically link the obb files to your external sdcard. It will still show the files on the internal tho, and it will show details on them taking space, but if you look at your memory, it really doesn't take space, so don't be confused.

 

If you are going to use ext4 you need to set the partition as secondary/slave and not master.

If set as master then the main system sdcard partition will not mount correctly so if set as master as ext4 you will need to rename the partition.

ext2 is slower and ext4 is faster and much better cache settings.

 

What's the difference between link2sd and GLtoSD? the directions make it seem like the same concept, except with link2SD you just start it with the icon?
