Today after 4 weeks , i crash my dji phantom 3 standard into tree and after that in the ground .
The phantom body is still perfect the plastic okay ,but when i power on the phantom i can not fly , he show _ accelerometer failed , and i read here in the forum and i understand there are two option : to smack the drone and to wish that work , or
To open the drone and take care of it - i choose this way , but what exactly i need to do ?
Please some help

Are you familiar with intricate electronic repair work?
How about the 3rd option - Call nearest DJI customer support and ask to ship the crashed/damaged drone in for repair.

i am think that i will not take the 3rd option because they are not very near to me , (i need to drive about 2 or 3 hours ) and they dont accept shippment , they want that i will come with the product .
and i understand that the second option is not so Problematic , i need to open the phantom (to open some screws ) and then to push out the black box with Tweezers or something like that , to give the black box some small beat on each side and to push the box in again , and to check the phantom . i am right ?

If you know which side hit the tree, you can sometimes "unstick" the accelerometer by smacking it from the opposite side.  I'd try a sharp medium hit on the opposite side from where it hit and see if that brings it back.  If/when it does, be sure to do a fresh cold IMU calibration, followed by gimbal calibration.  While you're at it, calibrate the compass before you fly next.

if i dont know the side , its okay to smash it in all the sides ?

Its clearly work ?

Check out this thread before you do anything.

Also use the search function here on the site and put in the word   accelerometer

It will give numerous threads of what other people have done.
