    Hi all.

    I've spent almost the full 2 days looking for solution of this but to no avail.

    My tablet is using 4.1.2 Jelly Bean.

    I owned the SM-T2105 Galaxy Tab Kids rooted. Then suddenly I was thinking to move all my apps to SD card. Trying and trying, finally I realized that I need to make separate partitions on the SD card first.

    So I one of the solutions I found on the internet told me to make that partition using the PC. Then I am interested to connect my device as mass storage instead of the default MTP connection. So I found this - https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler&hl=en.

    Without reading any further, I quickly installed it and turn on the mass storage function. But to no avail. My PC can't recognized the tablet anymore since then. Immediately, I quickly uninstalled that app and looking for another app. But still the same problem.

    So finally I am stucked with "connected as an installer" whenever I connect the tablet to my PC. And the worst thing that, I cannot change it back to MTP/Camera transfer mode i.e. my tablet would immediately reboot! I was totally intensed since then. After trying and trying, I still cannot find the solution.

    Then I thought a firmware upgrade will do. So i install the latest firmware for SM-T2105 - T2105ZHAND2 from here - http://www.sammobile.com/firmwares/download/32189/T2105ZHAND2_T2105ZZHAND2_TGY.zip/. I also rooted it again then.

    But still the problem persist. I also end up using the ADB terminal from my PC to issue the
    Code (Text):
    2. su
    3. setprop persist.sys.usb.config mtp,adb
    4. reboot
    But still the same problem. My device would restart immediately after issuing the command.

    I have also found somewhere this code but the issue is I cannot find that /sys/devices/platform/msm_hsusb/gadget/lun0/ path on the tablet:
    Code (Text):
    2. Mass Storage Mode
    3. ---------------------------------------------------------------------------------------
    4. setprop persist.sys.usb.config mass_storage,adb
    5. echo /dev/block/vold/179:33 > /sys/devices/platform/msm_hsusb/gadget/lun0/file
    7. Return to MTP
    8. ---------------------------------------------------------------------------------------
    9. #!/system/bin/sh
    10. echo "" > /sys/devices/platform/msm_hsusb/gadget/lun0/file vold
    11. setprop persist.sys.usb.config mtp,adb
    This /sys/class/android_usb/android0/f_mass_storage but no lun folder inside. Only nluns file is sound
    So I am really stressed with this. Can someone here please help me out?

    Factory reset would be my last choice.

    I was expecting something like system files update or something. Is it possible?

    Thank you very much.
