Trying to figure out directory structure bt-200

Hello I am trying to figure out how to write to file using the bt-200. I am using unity and c# to try and write an application for the glasses and I need to create and write to a txt file. I am using the line System.IO.File.WriteAllText (@"file.txt", data); to attempt this. What I cannot find is the proper path to use since I am unfamiliar with the devices directory structure. I have also tried to use path = System.IO.Directory.GetCurrentDirectory(); but this has not worked either and I cannot find the file I have supposedly generated. Any help would be appreciated.

Cant Figure Any Of This Out

I cannot figure any of this out. I cant figure out how to unlock the bootloader. I keep getting errors and when i try to find the android sdk stuff im lost. Its frustrating that i have to go through so much headache and not even have the bootloader unlocked. Ive read and re read the instructions. Ive watched so many videos and i cant get this right. This is so annoying.

"the program cant start because AdbWinApi.dll is missing from your computer. Try reinstalling the program to fix this problem"

Ive downloaded the adb files and still cant find them in my computer. This is so stupid.

"Invalid battery" anyone figure out why?

Given that practically every after market battery for the G3 seems to have horror stories about some people complaining about the "INVALID BATTERY" nags one would think somebody would've investigated by now why it's happening. Assuming the battery pins weren't smashed out of alignment what else would cause that? Something in the firmware? Something else?

Trying to figure out privacy settings (pic)

Hi.
Noob here.
Running RR rom and loving it.
Went to Privacy settings and found out there's an option to limit apps.
For example (see screenshot below).
My question is: should I even be touching this?
Thanks!

How do I figure out the permissions?

Basically, I'm working on a ROM, and I'm doing well with it; very few problems are occuring, and I've written loads of scripts to automate everything for me. It's a stock-based ROM based on Samsung's 4.4.2 firmware.

The problem I'm having, is I don't know what permissions are vital. I could copy all of the permissions, and then strip out the ones I don't need after I've removed or changed files, and I could automate that, but that makes my updater-script roughly 3000 lines long. A tad long.

How can I figure out what permissions I need? Or should I think about checking if everything in a folder has the same permissions, and then make that folder one recursive one (and keep working backwards from there until almost all permissions are conglomorated in recurive permission sets)?

Thank you very much and I hope you can help me.
