Ok so I updated to the codename 1.5.5 rom and also updated to franco's milestone 2. Here is where i believe the problem lies. for some reason his milestone 2 kernel will occasionally cause my gnex to get stuck at the google screen. I have to repeatedly pull the battery and try to reboot until it gets past that screen and eventually boots up. Another weird thing is if i try to go to my bootloader screen it wont give me any options besides booting up the phone it wont allow me to access the boot recovery and restore one of my nandroids very very odd. has anyone else encountered this? I'm hoping once he updates his kernel everything will be fixed but who knows how long that'll take I guess for now i just wont reboot my phone.
