I found a solution (Kinda),
This is a problem with both the LOS14.1 build 2018/01/09 as well as the 2017/12/15 build for the s3 mini I8190.
I put a micro SD card to put in my S3 mini and when I chose to format it as internal storage after about 3 minutes of being stuck on 20% I got the following message "java.util.concurrent.TimeoutException: Thread Binder:2972_B gave up waiting for partitionPrivate after 180000ms".
After restarting, the phone says the SD is corrupt, and then I can format it, but It says that the SD card is really slow. At first, I thought it was a problem with the format, so I tried formatting the 64gb SD card to fat32. Once that didn't work, I bought a V30 U3 A2 micro SD card and tried. It failed as well, so I formatted it to fat32 and still bad. Finally, I decided to buy a SanDisk Extreme Pro 32 GB V30 A1 micro SD card, but still the same problem.
I tried the manual method:
golden:/ $ su
golden:/ # sm list-disks adoptable
disk:179_96
golden:/ # sm partition disk:179_96 mixed 80
java.util.concurrent.TimeoutException: Thread Binder:2590_E gave up waiting for partitionMixed after 180000ms
//after getting an error, I continued as said
here
golden:/ # sm list-volumes all
private mounted null
emulated mounted null
//the volumes don't appear, so I restart and then reinsert this line
golden:/ $ su
golden:/ # sm list-volumes all
private:179_99 unmountable null
private mounted null
public:179_97 mounted 7B8C-1421
emulated mounted null
golden:/ # sm format private:179_99
golden:/ # sm format private:179_99
AND NOW I GOT 11.7GB SD CARD and the rest (58.92GB portable)
THIS WORKED, BUT IT TOOK 5 TRIES. I ALWAYS GOT THE ERROR "Error: java.lang.IllegalStateException: command '15 volume format private:179,3 auto' failed with '400 15 Command failed''"
SO PLEASE TAKE IT WITH A GRAIN OF SALT
