I discovered this one those days because of Android 4.2.x and its partition management, simply finding that Simple2Ext is not working anymore on it. So, I had to found another one good replacement of it.
It’s pretty simple and straightforward to install and use. You have to partition and format you SD card just like I’ve said in my previous article. Then you have to download and install Mounts2SD directly from the Play Store. With your MicroSD inserted in your device, open Mounts2SD and configure Busybox and Init.d scripts. After that just simply reboot, and after it finishes to power on (your device will vibrate 3 times) reboot again (just to be sure). Don’t worry: your device on you first power on will boot a little longer, because it’s moving all the Android framework on your EXT4 partition.
Yeah, nothing more to do. If you open up Mounts2SD and the status light is green you’re done. If it’s yellow, you have to see logs (probably you’ve not configure it and something else is broken). This app is made to work upon CyanogenMod 7.x, 9.x and 10.x (so Android 2.2 and up).
