[Q] Issues with USB data connection on Linux topic

After a while, Debian Jessie will just stop recognizing my phone. It will come up with and "MTP inaccessible" error and refuse to mount my phone. It still charges, but it doesn't allow me to transfer data to and from the phone. Any ideas on what could be causing this?

How to Root Nexus 5 (android 5.0.1) on Linux ? topic

Hello guys, I had root when I had androd 4.4.4 but uprading it to 5.0.1 made my root ineffective. When I open my app list I can still see there is SuperSU but when I try to open, it says "There is no SU binary installed, and SuperSU cannot install it. This is a problem!
If you just upraded to android 5.0 you need to manually re-roo - consult the relevant forums for your device."

Well thats why I'm here. I googled the "how to root android 5.0.1 on linux" term but there wasnt any way to do it.
I hope you guys can help me.

Why isn't there Linux style root on Android? topic

This is something I have been wondering for a while and after searching the forums and Google I have not been able to find a clear answer. As a long time Linux user the idea of running your system as root all the time is appalling. It is a huge security risk. But for some reason that is really the only way to gain root access on an Android device (as far as i am aware). Apps like SuperSU allow you to pick the apps that are allowed to run as root, but there is no password or verification that the entity approving the access actually has the authority to do so. I hear all the time that rooting your phone is a trade-off between customizability and security, but every Linux system has a root user and it is incredibly secure when properly administered. What is the reason for the difference?

From what I have read, it sounds like part of the issue has to do with Android handling users differently. I would love to be able to maintain a more limited root function on my devices. Thanks.
