I'm not sure I understand all of your questions. However, I dl install-tools-N810e.deb to internal memory, which I also dl to my PC. File size is same for both, which is 3,744. So, I have the correct file, right? System info. Do you mean version? If so, it's 4.2008.30-2. I don't know what you mean by external.txt and internal.txt. Where are those files located?
