Dead IMU/Strange Readings - Crazyflie 2.0

[0x746821]

Hi!

I have a crazyflie 2.0 which I haven't used for a few weeks now. Yesterday when I turned it on again for
the first time I couldn't get it to fly with the Android client. It just tipped over when trying to take off. When I
connected with the cfclient I noticed that something strange is going on with the IMU readings. Although
the crazyflie was placed on a level surface, the IMU readings were off by quite a bit (see screenshot).
Also when I move or turn the cf, the values do not change. When I last played around with the cf a few
weeks ago everything was fine.

Anyone got any suggestions whats going on, or how to fix that?

Thanks in advance,
Tom

Have you tried uploading/resetting new firmware? Maybe unplug and replug crazflie dongle and controller.

Yup, tried that already. No luck.
I am running cfclient 2016.4-29-g0ed6fda and flashed crazyflie-2016.11.zip firmware.

Edit:
OK, everything seems to work fine again.

What I have done:
Flashed "cf2_run_imu_manufacturing_test.bin" from this post: viewtopic.php?t=1233#p6762
After flashing this firmware, the IMU readings returned back to normal.
Re-Flashed "crazyflie-2016.11.zip". IMU readings are still good.
