Servo problem PLS HELP

[cyclopediatechtilon]

I was modifying my servo when i came acoss a problem.
The output shaft moves to 360 degrees but when i send the signal to the servo to rotate to 0 degrees, it only moves a little forward

So turn the pot inside the servo until it stops moving.

No i mean that i finished moding my servo.
should the hex of admin work for it to rotate continuously?

If the servo is already modded and moves when the MCU is sending the zero degree command then chances are you may have modded it improperly by accident. Also, have you checked all the voltages getting to your servo and MCU? Make sure there isnt a power drop into your MCU when both devices are running otherwise that could cause the MCU to put out the wrong signal.

Another thing,
when i was modding my servo, i rotated the pot head till thegears stopped moving.
but when i shut the battery and put it on again, the gears moved a bit forward and stopped
