I managed to enter to Download mode, try lots of flashing combinations (KPE full, KPU, KPQ)
In all cases, when ODIN says, PASS , and reboot into recovery, I got this message
E:format_volume: rfs format failed on /dev/block/stl10
E: failed to mount /sdcard (File exists)
E: failed to mount /data (No such file or directory)
I think the internal sd card is messed up. I don't know how to fix it. What should I do?
I search on google and found some other phones with this problem, but I don't think that might help our Samsung..
