I recently purchased a Coby 7033 tablet (black friday deal that only cost me $15), which was running ICS 4.0.3. After reading and trying several different sites, I finally found this site here and managed to get the device rooted (using the root method for a 7035, only difference between the model is the touchscreen, 7033 is resistive, 7035 being capacitive). After doing the root, the device booted fine, and the root was kept. The issue didn't start until I was copying over the files for the google play store. After copying the files, I went to reboot the device, and somehow managed to cause the device to sit in a bootloop on the android screen. I've tried to do the Master Reset, as well as trying to access the device via the ADB, however without being able to cut on USB debugging, I can't get ADB to connect. I noticed that there was another option named "Update from external storage" (Under the recovery menu). Is there anyway that I can fix/restore the device via this option, or am I screwed.
