My Problem

My Loud Speaker had gone bad.

My Fix

It went well without any hiccups.

My Advice

Go for it.. If you have to do it yourself.

My Problem

Yes, once. Now I have tho replace another two touchscreens!

My Fix

Well... a little difficult for me the first time.

I only follow this guy: http://www.youtube.com/watch?v=hTRXSMQ-GJY

... and the big problem was to get som kind of thin double tape or glue to stick the new screen...

My Advice

Nex time, I will follow (also) your N1 teardown:

My Problem

A broken screen on a Droid Eris

My Fix

It went well, this was the first phone I have ever repaired.

My Advice

Double check the inside of the glass before you close the phone.

My Problem

The power button on my Nexus One stopped working. In order to replace the power button, you have to replace one of the two boards. (The IO Board).

My Fix

I took a friends broken Nexus One and swapped the IO board. Its not as daunting as replacing a screen or digitizer, but give yourself some time. Also the tools provided by ifixit worked perfectly.

My Advice

There are a ton of little pieces. Label each screw that comes out because only a few are identical. Each go back into different places at *different steps* in the reassembly. Failing to get it right means you have to undo the reassembly and restart.

Also if you replace just the top IO board, you keep all your settings, root filesystem, and IMEI number and bootloader.

It does replace your camera, flash, rear speaker and a few other bits.

And strangely enough the IO board looks like an android.
