tl; dr 更新的cyanogenmod与rom manager，当它重新启动时它卡在此屏幕上：
我用yyanoon 7. revo 7. rom manager应用程序通知我的更新。我点击了一切，继续更新，一切似乎都很好;它关机，开始备份，然后显示一个具有大量文本和安装进度条的屏幕。完成后，它重新启动，显示最初的白色EVO 4G屏幕。然后它在上面的屏幕上面被困在半小时（蓝色箭头仍在圈子中圈出）。
TL;DR Updated CyanogenMOD with ROM Manager and when it rebooted it is stuck on this screen:
I have an EVO with cyanogen 7. The ROM Manager app notified me of of an update. I clicked through everything to proceed with the update and everything seemed to be going fine; it shutdown, started back up, then showed a screen with a lot of text and an Installation Progress bar. Once that finished, it rebooted, showing the initial white EVO 4G screen. It then goes the screen above where it has been stuck for more then half hour (the blue arrow is still circling in the circle).
Does anyone have any suggestions on what went wrong and what I can do to fix it?
Ok so I found the solution. It was stuck in a bootloop. Instructions can be found here.
YOU WILL NEED TO REINSTALL THE GOOGLE APPS SUITE (MARKET ECT)
