Dear friends,

First of all sorry for my bad english- I didn't have a practic for a long time.
Probably you can help me in my trouble with N1. I got a next problem:

Some time ago the microphone and speaker phone of my N1 became disconnected unexpectedly. After
disconnecting they not working constantly in the phone mode and in other applications both. The
headphones also not working. But! If then I'm push the "speakerphone" button during the call - I get
the possibility of talking (but only in speakerphone mode). If I want to call not only in speakerphone
mode- I must to switch off the phone at least for 10 minutes. After 10 min I can switch on the phone
and then it working perfectly till the next trouble.
I found the reason- it always happens after the bottom of my N1 is hot (battery sensor show me in this
moment 34 degrees or more. And this never happened when the temperature less than 34 degrees).
Our phones repairing workshops can't localize the problem, so i want to find the problem by myself and
request the specific kind of repair like "make solder legs of audio controller, etc". I don't see any

The questions:
1. Can anybody share with me schematic diagram of N1?
2. How to check the log of N1 errors (is it radio unit or no?) via the ADB (already installed); I need a step-by-step instruction.
3. Any other ideas

Thanks in advance!

Hi DPH159,

i`ve had quiet near the same probs with my N1
my probs are on calling someone or picking up the phone after incoming phone calls.

outgoing calls:

as far as i`ve test it...the dial-up is running well

but when i put somebody on speakerphone...i can talk pretty good but only on speakerphone-mode...but thats not the perfect solution
i can`t talk everytime via speakerphone ;(
