Thanks. You're right at the end. I am trying to do it by phone and avoid using my PC.Have you tried downloading to your PC and transferring over to the phone from there? I regularly have issues with the stock browser downloading files (though that surely is a small download.)
You could also try downloading to a PC and emailing to an account that you have on your phone and see if that works if tethering, for some reason, is something that you don't want to do.
Also: I am not familiar with that process. I have been doing everything eliminating my PC. I read through SCENARIO 4 OLD SCHOOL and there's THIS paragraph:
If you have a rooted phone, have the Android SDK installed, and are proficient / knowledgeable about using adb and flash_image, then you can follow these steps (note: I am purposely omitting some details that those familiar with this process should not need--if you need it, you probably shouldn't be using this):
So, without every step, I'm not attempting this. I just downloaded gscript again. I tried to open it even before I attempted to move it to SD and continue. It reads "NULL". For some reason, this file will just NOT come through to my phone (or open).
