Hi I earlier received the OTA for 4.0.3 but when 4.0.4 update was released I didn't received the same, so tried getting it manually done. Followed the steps mentioned here: How To Manually Update Android 4.0.4 ICS On Nexus S | ValueWalk Everything is going fine till Step No. 5... but after that I am facing an issue. When I select 'recovery' this is what happens: The screen goes blank The 'Google' logo appears for a second the 'yellow exclamation mark appears' The next second I see a 'red exclamation mark' over the android logo. The screen goes blank with menu buttons lights on. The phone restarts after a while. I am having a rooted 4.0.3 with stock firmware. Requesting assistance for the same.
