Hello, Sorry for the late reply. please follow the steps to test if the X728 issue: a:Take the X728 off from the Raspberry Pi, remove all the batteries, power supply, and all jumper caps. Then connect the battery or power supply, press the blue power button on X728, the blue LED should be on, and then press and hold the power button for more than 8 seconds, the blue LED should be off.(These steps indicate that the X728 has no issue.)

b:Please check and confirm if other device occupy the GPIO with X728.

If there is no problem with the above test，please test it like this： 1/Remove all jumper cap, 2/Remove all 18650 battery 3/Place 18650 battery again and wait a few seconds before testing.

If your x728 is V1.2 version； Please check if enable the ASD function (shorted the ASD header), if you enable the ASD function, please make sure your operation is right: first, place the battery into the battery holder, insert the jumper to ASD header after 3 seconds,this is very important!!

Still not find out the issue, please attach a video to contact us show more details.
