[Q] Phone constantly showning "No Service" - Nexus One Q&A, Help & Troubleshooting

Hey
I have a little problem which has rendered my N1 practically useless as a phone. I was on MicroMod's Gingerbread ROM for some and all was going fine. Today I decided to switch to CM7 nightly. It worked fine but after a reboot I realized that my phone was not connecting to my network. I rebooted, wiped and reflashed, tried a different sim, tried a different rom. Everything. It just isn't working. My network bars are grayed zero and there is a small cross on them. My notifications show my Service Provider's name (Airtel), and on the lockscreen it reads: (No Service)|Airtel. I went into network operators in settings and it says searching for a while then a toast notification pops up saying that there was an error while searching for network. What should I do? Any help will be appreciated.
Regards
Raptor
P.S.:It's not a network problem. I tried using my sim in another phone and it worked just fine.

Never mind actually. I fixed the problem. The device would sometime start connecting to the network properly for a few minutes. The 5th time that happened I went into mobile operators in the wireless and network section of settings. From there I selected my network and rebooted. My device has been working perfectly since then.

Lost my data connection. No Icon or anything. Help!

No longer have any data connection. 3G/E/H etc is gone. No icon at all.
I've tried a couple things:
I tried airplane mode on/off.
I tried the *#*#4846 thing and disabled radio there. I changed the network band. I tried "Enable data connection" there and nothing happened. I made sure it was enabled on boot.
I removed my sim card and put it back in. Started phone with/without it.
Wiped the phone in recovery. Reflashed Cyanogen/gapps.
Reflashed the radio.
Tried Modacos senseui just to give it a shot. Still nada.
NOTHING is working! Anyone got any ideas or any other fixes I can try?
This is really killing me...
ok i had this problem last week and this is what i did and it worked for me.
1.Settings
2.Wireless and Networks
3.Mobile Networks
4.Access Point Names
5.Make sure it says epc.tmobile.com
if it doesnt say that then just add it and when u finish just hit save and wait a couple of minutes and there should be a E/H/G Hope that helped.
sounds like a carrier issue..i have had this happen with tmobile in the past .. just typical network gremlins..

[Q] 3g will no longer connect

I installed CM6 onto my sister's Hero as well as my mom's Hero. My Mom's Hero works fine but my sister's will not connect to the 3g network! I have gone through and turned on/off all of the network settings and can't get it to re-enable the data services. Wifi works, calls/text work, just not the internet connection over the mobile network. I tried flashing Fresh to see if that would work and I get "Data Call Failure - Error Code 67 .Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again." repeatedly. The 'Mobile Network' in the settings menu in Fresh stays stuck on "Turning on...". I don't get that error in CM6, however. I've tried reflashing/wiping as well with no luck. Is the 3g radio separate from the radio that does calls/texts? Is there a way to check it? I don't want to tell her that I broke her internet connection :/
What radio are u using on that phone? And what all have u wiped?
Root-Hack-Mod-Always™
I was using the most recent radio I believe, 2.42.01.04.27, and I tried wiped everything in recovery. I continued searching for an answer and was able to find a thread that solved my problem! http://androidforums.com/sprint-her.../13197-data-call-failure-error-code-67-a.html
I just had to go into system updates in about phone and perform a 'profile update'
When I first setup her phone she couldn't remember her gmail password so we reset it and she was able to log in. I completely forgot but her 3g worked for that day! the NEXT day we noticed it wasn't working and it stayed like that for a few days until I was able to fix it now. She set up her gmail account at the sprint store when she first got her phone, could her gmail password somehow be related to her PCS username/password so that changing it screwed up her ability to login into the sprint PCS service? I'm still confused as to why this happened on her's but not on my Mom's phone, and never on my phone!
I had this happen saturday night,, running dd 2.8.. data would not start for nothing.. I nandroided back.. and all is good!!

Problem connecting to my network Please help!!

the weirdest thing happened to me, my phpne was working fine, i flashed fearkill fr13 after a full wipe coming from fr12 mcr.
It worked well for a couple of hours and all of the sudden i cant connect to my network. The only way it connects is by enabling 2g networks only and even like that i cant make any calls. I have even tried reinstalling the baseband 405 and nothing works...
My network is fine by the way, its just my phone
Please help me!!
Edit:
A little more info:
I tried a different sim card with the same results
Whenever i try to search for a network it just stays thinking for a while and does nothing
When I try to do it automatically it says it cannot connect to the network at this time immediately...
I managed to make a call on 2g networks only but as soon as i remove the check i cant connect
Edit 2:
Woooooow, this just gets weirder by the second!!
I can connect to the internet with wifi disabled and a clear X on the network as in no network connection... I can browse the internet just fine, NO CALLS though
... after countless Wipes and installing plenty of roms With no luck i gave up and as soon as i Woke up it Was Working again... strange but im happy
Guess it was your network after all
maybe, i had a blackberry beside it with a working 3g connection :S
And no idea how to explain 3g working with no bars and an x on it haha
O have problems with my network connection too.
In some rooms at my house I can get 3G access and in another room only EDGE.
Several times per day I can't get access to the network anyway. The only way to solve the probölem is to restart the phone.
Sometimes my phone tells me it is connected but there is no data transfer for several hours. I noticed that when I got home and many emails from the last hours appeared after being connected to my wifi.
I'm using the MCR but I've also tried the ROM from romkitchen-org. Changing the baseband had no effect.
I'll have a try with the stock ROM. If this would fail too I'll send my phone back to the dealer. I think it could also be an hardware defect.

[Q] Mobile Network - Connection Failed

I turned my Mobile Network (3g data) connection off for the night to conserve battery, and the next morning when I tried to connect again via the quick settings, it didn't connect.
Under settings it has the caption, "Connection Failed".
The network was working fine for ages prior to this, and on a few occasions, turning off Mobile Network for the night was fine.
I've tried resetting the phone and taking out the battery + SIM for a few minutes.
I've also tried re-entering APN settings with no luck.
I'm with Vodafone Australia, running the stock 2.3.3 virgin au rom.
Nobody else on vodafone is failing (relatively speaking )

Update:
It was a 3G widget messing everything up, thanks letmedanz
Any ideas?

Did you try wifi connection?
just wondering..
i am quite certain your problem is with the apn settings.
try deleting the existent apn and enter a new one. save it and try reconnecting...
though not very important, you could check for the port number to enter in the apn settings with vodafone.
also, if you are using any third party apn modification tools or even a simple 3G on-off widget, the settings do get wasted.
if you do, uninstall them, re-enter apn settings and try

[Q] Cannot Establish A Wireless Connection

Hello everyone new to this forum so first of all would like to say hello.
Now I am experiencing a problem with my Desire 510. I just rooted this phone a couple days ago and everything has been great. This morning had a notification saying SuperSU needs to update binaries. I updated that through TWRP and seemed successful. However after this the phone rebooted and ever since then I am getting notice saying "Unable to establish a wireless data connection EHRPD: 33". I get this when it is connecting to LTE. However, when I go to mobile connection settings and select CDMA only it connects to 3G with no problem and I can get online. Is this problem related to rooting my phone somehow or is it possible I am just experiencing this problem because of Boost Mobile right now?
-Thanks for the help
Jordanh151
While on CDMA only I "Updated Profile" which was successful and then my phone rebooted and is now connected to the 4G LTE again so that seemed to solve the issue.
Still wondering though if this issue was or could have been caused because I have rooted the phone?
After factory reset I can't establish a wireless data connection. Every time i tap an app message pops up it has stopped. And I cannot get into my settings to do anything. Please help. Thank you
