Hello, Just bought a RTF kit from Banggood.com and downloaded Libre Pilot and updated the firmware to latest one? and since then, drone is not arming. I did double check on transmitor settings, arming sequences, and even tried to flash with previous ones with no luck.

in my health monitor, ATTI is Crossed out, and STAB is highlighted red. and seems like gyro in the drone is not responding to libre pilot live monitor.

Please help. I tried everything i can think of and still cant figure it out

You should wait with the frame steady for Gyro initialisation.

Try disabling (uncheck) the Attitude > "Wait until the board is steady" option

or

Increase the BoardSteadyMaxVariance value using the UAVOBrowser, should be needed if your accelerometer is really noisy.
- System tab > UAVOBrowser, search for BoardSteadyMaxVariance.
- Change value
- Save (HDD icon with Red arrow)

Thank you for your help, btw how long should i wait for the gyro to stabilize?with battery plugged in or out? and in what screen? also what is UAVO Browser?

Should take a few seconds. Steady board is mandatory, do not move, without vibrations.
Powered using USB or battery the Gyro init is the same.

You can find the UAVBrowser in System tab.
