Since last night, my phone has been stuck on the rainbow screen during the boot up sequence. It will start with the regular Google name and then go to the animated rainbow prism graphics. However it stays in this animated rainbow graphics sequence forever. Phone - Samsung Nexus unlocked Network - AT&T Network 1) Tried a factory reset, which was unsuccessful. 2) I've somehow got to a safe mode at one point, where I uninstalled the last few apps (Yelp and a flashlight app). Then the phone rebooted by itself and is stuck again in the animated rainbow prism graphics. 3) Pulled out the simm card and could get it to load. However several failure to load messages appeared for several droid processes and app processes. Then the screen went blank. Thoughts on other things to try? Thanks in advance for the problem solving help.
