Replacing my iPhone 3g's defective vibrator

我的问题

It suddenly stopped vibrating one day.

我的修理方法

Super smooth. The guide from ifixit was amazing. Very simple and easy to understand.

我的建议

A very important instruction was missing at the end of the guide. Once you rip apart your iPhone completely and fix it back there's no way that your iPhone would switch on unless you hard reset it.

I was very worried to see my phone not switching on after i replaced the vibrator and fixed everything back in place. I had to go through some stuff on the internet to find out that i had to hard reset it for my phone to start running.
