Similar problem with a Samsung NT5110, in an unstable state. That is it starts up, partially, and displays the reboot..factory reset.. clear cache menu.
Samsung will do a "depot" rebuild for $160 US. Thus, my attempt to reinstall from a Linux/Ubuntu 14.04 system. I do not have a keyboard for the Samsung device. The Samsung is found by lsusb, but mtp-detact fails. mtp-detect Unable to read MTPZ public exponent from ~/.mtpz-data, MTPZ disabledlibmtp version: 1.1.6 Listing raw device(s) Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
