Okay sometimes my N1 will lose all service and in the Notification Bar it will display "Emergency Calls Only". This doesn't go away and I don't get service until i restart my phone. I don't understand why it does this. I am running CyanogenMod 5.05 and my carrier is Cincinnati Bell. What can I do to fix this?
I do see this sometimes (albeit rarely) in areas where T-Mobile has low coverage (I guess that means it would roam to AT&T to make a 911 call if needed).
But as soon as I get into an area with good coverage it's solved. I don't have a need to restart the phone.
What radio are you using? Have you tried also just turning off the radio and turning it back on, or for example toggling 2G only? That might trigger the radio to re-connect.
The radio I am using is EPE54B.
Your explanation as to why this happens sounds reasonable. The location that I normally see this happen does not have the best coverage.
Next time it happens, I will try toggling 2g only.
Is there another way to turn the radio off and on without restarting?
Airplane mode. But be warned, toggling 2G or turning Airplane mode on/off usually doesn't work with this issue. A reboot is generally faster.
Also FYI, if you aren't aware, you can soft reboot by holding down Trackball+Power+Vol Down. Click all three simultaneously and the phone will reboot within a couple seconds.
I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.
Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.
Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.
Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.
Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Is this not the same then as just shutting off data?

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.
I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.
The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.
ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.
I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!
I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!
I just installed Cyanogen 7 on my Nexus One, and couldn't be more pleased. The problem is, my phone now switches into Edge mode for days at a time, for no real quantifiable reason. It then seems to switch on its own, back to 3G/HSDPA. Does anyone know what could be wrong? I've tried rebooting the phone to no avail. Any help would be appreciated.
What's the signal level or the area that you're in? Could it have anything to do with coverage?
There's an option in the mobile networks settings to toggle between 2G/3G, but I'm not aware of it being set by itself. This toggle button can be placed into the notification power widget toolbar, maybe it's getting set there?
Another thing to look at is the 'Phone info' with the *#*#4636#*#* menu. Near the bottom there's a drop-down for 'preferred network type'. From what I understand, 'WCDMA preferred' will try to use 3G if it is available with a lower signal threshold than 'GSM auto (PRL)', which will prefer 2G unless the signal for 3G is much better. I know that this value changed when I toggled between 2G and 3G with the notification power widget.
Is there a pattern to when it switches between 3G and Edge, either based on time or location? How is the signal/coverage in your area?
I live in downtown Chicago, and consistently got 3G before this. I don't think it's a signal issue as it randomly comes back to 3G/HSDPA and stays there in the same areas before going back and sticking on Edge.
I'm set to WCDMA preferred. Should I change that?
There seems to be no pattern, no. It's very strange.
Guys, check out this Toggle 2G by TheMasterBaron:
http://forum.xda-developers.com/showthread.php?t=739530
It works for me. I flashed the signed version via OR and then installed the Notification plug-in apk so that I can control when it should or should not toggle from 2G to 3G,
bcs sometimes I turn on the screen to check the time or sms or use some non data related apps....so not necessary to switch to 3G when screen turns on.
I am not sure what rom You are using but on CM7 it's better to use 2G/3G toggle form notification bar (toggle 2G takes memory). To preserve battery life I am on 2G almost constantly. One thing to notice that 62KernelTweak speed up 2G noticeably. I am very rarely use 3G as 2G is fine with this tweak. I am form Poland, Play network.
Edit:
I don't noticed any improvements in wifi or 3G with 62KernelTweak
Hi,
I once heard that some modems can change from 2G to 3G and vice versa, so that when you have data on, you'll be connected to 3G (or H, for that matter) and when you turn data off, it will automatically change into 2G.
I want such a modem since I get much better signal with 2G, so my device consumes much less power, but it would be nice if I can turn data on and have it change to 3G/H, without having to uncheck "use only 2g networks".
Is there such a thing?
Thanks.
Not that I have knowledge of and im almost certain that's controlled by the ROM it will only auto switch when 3g is out of range
