[General Questions and Answers] Donphillipe:
First of all if there is any way for those like me with less than perfect eyesight and experienced with the structure of these most complicated I've seen to date, I would like to respectively ask that the captchas be reduced in difficulty.

My issue is that I seem to have hit an impasse in that I can't post a question here to a How-to guide published for non-experts unless I am an expert, qualified by posting 10 helpful comments in an area I am just beginning to learn. If I think back to other operating systems I have learned over the years other than Linux, there were sometime years that passed before I felt qualified to help someone with understanding the OS.

So I am in a catch 22.

All I want to do is make a backup with a possibility of restore of my full OS on a Blu Studio 5.5s that I have factory reset for just that purpose, to have a customized OS that I could restore. It would also be nice to be able to learn how to someone share this image online, assuming that others can use it where none are available otherwise, but that is my second objective and not the first.

Now understanding my first objective is just a backup and restore capability and also understanding that the two bootloader recovery packagers out now don't (yet?) support my phone, I at last found this article and was excited that it would accomplish what I needed. I went through the hoops of days of research, getting hardcodes out of Windows device manger, altering Google driver INF files with dummied up hardware codes with a new device, overriding windows and getting the drivers installed and to work, installing the 64 bit version of SDK, and careful with the 32bit Java, relocating, renaming the SDK, modified the PATH to find my variables, installing Cgwin64, researching and comparing old package to new info and testing it all to see that it worked.

So in short, I am stuck in the middle of this how-to guide with my phone stripped to the bone for a backup but I can't ask a question here until after I have learned the answer to the question I am asking.

THE QUESTION:

reference: http://xdaforums.com/showthread.php?t=1818321

My phone directory structure is not documented online and does not match the examples in the backup guide, plus it appears I may also have some permission restrictions? How do I continue? Thanks

My results thus far:
