- I am running a rooted Nexus 7 2013 using marshmellow version 6.0, build MRA58K.
- I want to upgrade my Android to the latest version 6.x.
- There is a System Update available prompt, which I cannot use since I am rooted.
- I have used Wugfresh in the past to root as well as update while rooting, but as I rarely use the app, I get confused whren I use it and I am trying to finf an easier way
- The mini usb plug on the Nexus 7 is not very stable, so I want to try this without having to plug into my laptop.
- I have Titanium Backup and I want to take my backup data and copy it over to my Windows 1 laptop via Filedrop. I will “unfreeze” my frozen apps before this backup.
- I will delete the backup files from my Nexus 7, as my space is tight and there is no SD card for the unit.
- Then I was thinking of derooting my Nexus 7. Any recommended ways to do this easily and safely?
- I then plan to then use the conventional Android System Update.
- After the update, then to root my device. Any recommendations of ways that I can do this without being plugged into my laptop would be very helpful.
- After it is rooted, I plan to restore the titanium backup files that I have copied to my laptop, using Filedrop.
- Problem is that I have never done this with titanium backup and don’t know how exactly to restore everything.
- After that, I should be done.
Thanks in advance for your time and expertise.
