nexus 10 post flash

OK, I have rooted, unlocked, installed twrp and busy box...all that stuff as the directions say wit no problems. However, once reboot after successful flash (or, so it says) nothing is changed. The background does nit have Kali on it, the apps are available (hacker KB, etc) however all the icons are the little green android and when u try to open them the all crash with the error saying they have unexpectedly stopped. I have been at this for several days now and finally came for help as I am stuck now. System is a nexus 10 with android 5.1.1 installed, tarp, busybox, rooted. Any guidance would be deeply appreciated.

I literaly had the same problem on my nexus 9... In order to fix my problem, I had to downgrade my android 5.1.1 build. At first I had the LMY38T build and it was pretty glitchy just like yours. Once I downgraded to 5.1.1 LMY48M everything went smootly. You can easily get the factory zip to flash stock at the following link: https://developers.google.com/android/nexus/images. Then all I had to do is to reroot your device with TWRP as a custom recovery and then flash zip with nethunter available at https://www.offensive-security.com/k...nter-download/ . Anyway good luck dude !
