KK to 6.0 - Nexus 5 Q&A, Help & Troubleshooting

Hey people. Can someone point me towards how I can upgrade to Marshmallow from 4.4 without losing root? Additionally, what is my next option for restoring all of my apps with data? Apologies for the noob question - haven't been flashing things on my phone since Kit Kat.

What's the problem with rooting again? You can upgrade without losing data if don't flash userdata.img.
You can restore your user data with TB, adb,...

you don't need to restore data if you skip flashing userdata.img

You can use the flash-all.bat in the factory 5.1 image as long as you remove the -w. The -w is what tells it to wipe. Once that is done, you will be on 5.1 and you can then re-root by booting into a custom recovery (fastboot boot recovery.img) and installing the root.zip from there. That will get your root back.
Since you are already rooted, I am assuming that your device is already unlocked.

Downgrade from 5.1 back to 4.4?

I just updated my Nvidia shield to Android 5.1
They changed the UI and everything and I hated it,
is there a way to downgrade it back to KitKak 4.4 without losing my data?
No, after downgrading you will probably be stuck in a bootloop so you have to do a factory reset.
You have to get Titanium backup (needs root), backup apps and data, then flash an older factory image, root again, restore apps and data with titanium backup.

Of course. Do not flash userdata.img.
