Hi, yesterday I received an OTA with 2.2.1. After unpacking and installing the update my phone rebooted as normal. When booting the Nexus-logo appears, but afterwards the display remains black. There are indications that the phone boots up as normal, as I can hear the sounds (ex emergency-call) when pressing the display. The display works perfect in boot-menu (rescue etc) I've tried to do a factory reset and pulled out the battery several times to try to reset - all with no luck. In addition I've placed an update.zip on the sd-card in order to perform a new manual update, but after choosing recovery, my phone restarts and the screen turns black. Any idea how to solve this?
