Success!




I hadn't installed Lollipop on my 2012 Nexus 7 (Grouper) because of all the problems I read about but I decided to try it through using Multiboot and keeping KK 4.4.4 too. I now have Lollipop running, including most of the apps I have running in KK, without any apparent problems. I initially installed Lollipop as the secondary ROM. After Lollipop is installed as the secondary ROM, it takes a while for the boot process to complete the first time, it seems to take forever. In order to unlock and root Lollipop I had to make it the primary ROM and used Nexus Root Toolkit running on Windows 8.1 to unlock and root Lollipop just as I had with KK. Now I can alternate from KK to Lollipop and vice-versa.




This is for Nexus 4 but works the same for Nexus 7 if the correct Lollipop version is used:

Hi
Did yolu installed also kernel for lollipop? Or are you using KitKat kernel? I tried to install as you described but lollipop always directs me to recovery.
