need help here. I to tried rooting my Nexus 9 and have ended up getting it into an endless loop of it trying to optimize apps.
I did see Firelord's post to do this...
Using Firelords' and Jan's suggestion is was able to unbrick my device and get it working again.
Downloaded the Lollipop 5.1.1 image for Nexus 9 on this site: https://developers.google.com/android/nexus/images Unpacked all the files into the folder where I had fastboot.exe. Started my tablet by holding down the power button and the volue up botton to get into some kind of recovery mode.
Being new, what I don't understand is how do I get that file into the Nexus 9 if I can't get it to stop the boot cycle. I am pretty good following directions if there is some step by step way to get out of this mess.
Thanks for any help!
