How to turn a portable SD card into internal storage via ADB command?

Question

Android 6.0 Marshmallow’s introduces Adoptable Storage, a feature that allows use a SD Card as internal storage.

Is it possible to activate adoptable storage via ADB shell commands?

Answer 1

I managed succesfully perform this operation on my LG K8 LTE. I want to notice there are "500 xxx Unknown disk" errors problems, and give solution to avoid this. Solution is very simple. Proper steps in ADB would be:

adb shell
sm list-disks
// HERE YOU GET YOUR DISK ID, SOMETHING LIKE "disk:179,64" - REMEMBER THOSE NUMBERS
sm set-force-adoptable true
// IN NEXT LINE, SIMPLY PUT THOSE NUMBERS AFTER "disk:" AND ALSO AFTER WORD "mixed" TYPE PERCENTAGE OF SPACE LEFT AS EXTERNAL, SO IN MY CASE:
sm partition disk:179,64 mixed 60
// IT TAKES TIME. BE PATIENT. WITH THIS LINE I TRANSFORMED WHOLE EXTERNAL SD INTO 40% OF INTERNAL AND 60% OF EXTERNAL
sm set-force-adoptable false

BANG! That's it! Now go to storage and usb, there click on internal part of SD and expand options, click on "use as internal" or something like that, last option, (I cannot see what was that because I already clicked it and everything works) apps are finally going on SD with OBB files! ;)

Have a good day!
