I've read this thread (and others) and tried towelroot several times on my Galaxy Note (1), Japanese docomo version SC-05D, but it doesn't work. Is there any way I can make a log of towelroot's operation, and would that be helpful in troubleshooting? Is there another way to root this phone without using an external PC?
Model number SC-05D (Galaxy Note (1), Japanese docomo version)
Android version 4.1.2
Baseband version SCO5DOMMSI

Build number JZO54K.SC05DOMMSI
The SC-05D is an LTE version with a Qualcomm Snapdragon S3 APQ80060 1.5GHz processor/chipset. I think it is most similar to the Korean version than anything else.
Update: I had already reset my phone and had not checked USB debugging. After enabling that, running towelroot now immediately gives the message, "This phone isn't currently supported."
