Really needed ?

  • Now grab a hold of the "Battery Removal" tab that is attached to the battery, located at the left side of the back portion of the phone. Lifting up on the tab should remove the battery out of the phone

Use of an old credit card to help lift the battery Is much easier.

  • Not needed step. You Can remove motherboard without removing this flex except if : you want to change this flex or change the touchscreen assembly. Using a pry tool, gently pry the side control buttons assembly away from the case.

This step Is absolutly NOT needed for motherboard removal.

You will people brake flex doing so. Limit your guide to necessary step only!
