Exclamation Tab 3 7.0 SM-T210R Stuck on Logo

Hi i have a problem, i have flashed Stock Kitkat rom v1.7, but i dont liked because dont have the option to swap external sd card to internal, so i enter in recovery mode, i made a Clean install wipe with PhilZ recovery (deletes everything including the rom) to go back to 4.1, but I was wrong, and instead of selecting to choose install zip, select it will reboot, obviously with the Clean Install no longer had rom, but now stays at the Logo Tab 3 and can not get into recovery mode or Downloading mode to flash a new rom , i tried to conect to Odin, and Odin Recognize but stuck on Setup conection, i think is because my computer is not installing the MTP USB DRIVER (i have downloaded that driver from internet but still not working)

that I can do? I lost the recovery mode? the downloading mode?
