Finally rooted thanks to @siryarbles . Here are some hints that may help:
User: Everything you need is in this forum. In the upload part try to understand how the machine is processing U-Ls, what process first and what next and how htaccess works. Read the code carefully and check ad—s headers from examples.
Root: If you have already found this blog about a-t M–M is the right one. But you will have to do some changes. First, a-p sp—ing is not going to work. Remember network layers… There is a var that a-g uses in some cases. You might have already seen it with s— -l. You don’t need D-S sp—ing either. Just give to the box what it requests. You can use the same thing you found in that var but in your side. After that just read outputs and fix trees.
PM me for hints.
