How to skip 3D accelerometer calibration after firmware reflash?

[amilcarlucas]

Then you need to manually re-calibrate every time.

There is a procedure to bypass that, basically telling the FC to thrust you and the parameters you just restored, but is is not simple enough for general users. But it is documented in the wiki somehere and mentioned here:

How to avoid the calibration on 3D accel again after restoring the all saved parameters from file?

In full parameter tree, do a printscreen of all INS_ACCEL_ID# and COMPASS_ID#, then set them to 0 and hit “write params”. Then enter the previously screenshotted values, hit “write params” and reboot. You should be good to go. Remember that this procedure relies on the fact that you have previously performed a good calibration and it only clears the prearm checks.
