[Q] Please help me, no 3g, then no data at all - Nexus One Q&A, Help & Troubleshooting

I bought nexus one from my friend.
I am currently using HD2 with 3g data.
When I plugged in my sim card to the n1, it only worked with edge.
So, I seared internet for some information and I found out something about "*#*#6436#*#*" and change the setting to WCDMA only. Then the phone got no signal at all, so I changed back to WCDMA preferred. Then I did ping test but it did not seem to work very well.
Then I played with some APN setting and I realized that I lost data connection completely (phone still working)
I have tried to reset the phone but no luck.
Can anyone please help me with the problem? I am using T-mobile.
Thank you.

Pull your battery, and look at the back of your phone. At the top of the dark area there are numbers, look at the PB or FCC ID numbers. If they end in 9110 then you have an AT&T version of the phone, and the hardware will not work with T-Mobile's 3G service...

are you in the USA? you need to list your location. it is likely that you purchased the wrong version of the nexus one. there is an ATT version and a tmobile version. each only works with the proper 3G. so an ATT n1 on tmobile only gets edge, and vice versa. check which version you own.

Roaming

Hi,
Have a big problem in that whenever I put a rom on my new Tilt 2 (which I am running on the new HSPA Bell network). My phone thinks it is roaming.
This is a real pain and I can't seem to find away around the problem.
Please can somebody think of something I might be missing?
Thanks!!

Are you sure its roaming and not mistaken the icon for something else? Also, if you are indeed roaming, which network is it? AFAIK, in ON, there's only 2 HSPA network Rogers/Fido or Bell/Telus. Who is your provider?

So I have the icon telling me that I am roaming and all the application warn me before they download data that I am roaming as well (which is a right pain!!).
I am on the new Bell HSPA network.
Any ideas?
roaming..
ok .. this is my experience about this problem ..
first my home base is Netherlands ! and im using Telfort network on my nokia .. buat the last 3 year .. Telfort using KPN Network .. if you turn ON the phone .. it will display Telfort .. but a few second it will change to KPN ...
maybe.. your operator also using another network...
if I put my Telfort sim to TP2 it will display Telfort but with with ROAMING icon !!!

Bell have their own network here so I dont think that could be the problem. I also have a Omnia 2 and an Iphone 3Gs that dont have this problem.
Also just tried to manually join the Rogers network and as I thought it would not let me connect.
It is only on the tilt2 after I flashed a new ROM onto it.
Thanks for the idea though.
Anybody else?

EDIT: read this first and then try the following suggestion
Try setting in the TP2 band selection to only HSPA and see what happens. Since bell has no GSM, and if your phone is set to 2G mode only, it's falling back on Rogers/Fido, hence, the roaming.
Start>>Settings>>Personal>>Phone>> Goto "Band" tab>>Set the GSM/UMTS band to "GSM (1900+850) + UMTS(1900+850).
Play around with the Network type by switching to GSM only or CDMA or leave it on Auto.
FYI Rogers/Fido and Bell/Telus HSPA network runs on 850/1900 band.
Food for thought....
Also another thing to consider, considering that Bell/Telus HSPA network is new, I thought i read somewhere you have to get your device "added" to their new HSPA system. Right now, only new sign-up's gets on the new HSPA network. In other words, your phone is trying to get on Bell HSPA network, but Bell rejects it since it's not in their system, so your phone hop's onto next on the list, either roaming on Rogers HSPA or Rogers GSM.

Thanks for the detailed response.
I dont think I am on the Rogers network as I get the Bell operator logo appear and the phone stays on 3G (as I cant drop to Edge because Bell dont have it on their network).
Also checking my online billing from the past few days I would expect to see some nasty roaming charges which I dont have.
Finally I also have a Jailbroken Iphone and that works on the network fine without any problems.
Its just very weird!!
Just tried to connect to the Rogers network manually and it will not let me connect. So it must be something wierd on the device.
Oh, it does show Bell operator logo. I thought the phone was registering on another entwork other than Bell.
Hmm, since you are not incuring roaming charges, only thing I can think of, is the network list that comes within the ROM classifies Bell as CDMA and not updated to reflect it supports HSPA. So it reads the network id as Bell and network type as HSPA and thinks its roaming? I dunno, i could be wrong lol! ::shrugs::

Make sense to me
I guess I can live with it if I need to. Does anybody know of a way to force the device not to flag any messages about roaming?
At least that will make it less annoying.

[Q] 3g problems nexus one

hello every body
i have this problem with my nexus one when i am connected to 3g service (umts,hsdpa,Etc'). i can't make calls or receive any calls, i can't use the internet (data) or get sms and Etc'. but i have full bars reception. when i check the vi in setting to "use only 2g" the phone work great.
i tried everything downgrade/upgrade roms,radios. i tried to go back to my first backup and even do PASSIMG but nothing help i googled it every where but nothing
please some one can help???
without 3g the smartphone is useless
thanks,
shushkis
What network you on? I would at least see how old the sim card is.
Lots of time if you have an older sim card it just can't handle a newer system.
I am connected through Orange IL
and i tried switching sims even with other networks.
and more the phone worked fine at the beginning it just happened i remember i switch to one of CY roms and it happened
Have you tried a full wipe and reinstall the rom?
yes of course i tried customized roms and stock roms but nothing helped
I would check your apn settings...
apn connected to taking or getting calls?
i thought it's just for internet connection
Its just a guess.
If its a problem on multiple ROMs, its likely to be either hardware or settings. Settings are cheaper and easier to test, and that's the only setting I can think of...?
Of course, doing a full wipe (including system), installing a new ROM, and testing before you restore any apps and settings may be another way to test, but since the apn settings are pre-baked into most ROMs, it wouldn't rule our the apn...?
OK I tried to put apn settings and it didnt help
you say hardware?
but when I check in settings "use only 2g" the transceiver works great .
maybe the nexus have two transceiver one for 2g and one for 3g?
seems un-logical
No there are two radios one for 3g and one for 2g because 2g is for calls and 3g for data but when 3G is unavailable the phone will use the 2g for the data.
The Same Trouble
shushkis,
I have the same trouble, my 3G connection works so bad, but if I use only 2g connection, all works good... I have no idea what happend with my N1. I have a N1 for 3G 850 (AT&T) model.
Thanks for advantage.
So maybe the problem is the hardware? if the N1 have two inidvidul transcivers?
I have also the same problem. I've tried many different roms and radios. I use 900/2100 3G. What's strang is that 3G works perfectly at home, but when moving to another tower I get emergency calls only warning. 2g works fine.
I just started having 3G issues at home. With 3G on the phone reboots like once an hour, but on 2G I've gone days without a reboot. My 3G signal is not the best at home, but I don't know why that would make the phone reboot. I'm on T-Mo USA.

The one I'm using is only a couple months old, and it works well in my Desire HD, and my Moto Defy. It's only the N1, but I guess maybe it could be that. I'll look into more.
If it's only a few months old, then it may nor be the SIM that is the problem. I suggested it because a number of T-Mo users were having similar problems after a recent network upgrade, and a new SIM seems to fix the issue for most...

[Q] no 4g or lte on stock or custom rom

So I've had this phone for almost a week now and I used to he able to get 4g LTE. But ever since I rooted it, I no longer get more than 3g. I now have bananacakes Holiraider 1.6 but I still don't get any higher than 3g. So my question is how do I get 4g and 4g lte. Oh and if anyone is using that custom Rom, is it possible to get faster than 1512? In his thread it shows you can clock it to 1566. Thanks a bunch I'm kinda new to this!
try dialing *#*#4636#*#* and see what your modem is set to, it should be GSM/WCDMA/LTE auto
you also may have an APN issue, verifiy that your APN is correct, perhaps contact your carrier for the correct APN settings for you phone and plan.
Well I'm now running a custom ROM. The apn is the same as other users and it does say the above. And yes I am in a 4G LTE area
Sent from my HTC Raider X710e using XDA App
Try doing the above and change to LTE only.
Then once you have 4G change it back. It should stay on 4G. I had to do this to get 4G on official rom.
Ok I just tried that but it wouldn't let me to switch it to LTE only. When I did, it switched it back to GSM/WCDMA/LTE auto. I'm just gonna relock my phone and set it back to the original stock rom and format my phone (yes I have the apps and stuff backed up). Because my actual mobile connection fluctuates on and off as well
the phone should be locked into the GSM/WCDMA/LTE setting. If you try to change it from that setting it just returns back. The phone will get instructions from the carrier's base station to tell it whether to be on LTE or just 4G/3G. Using *#*#4636#*#* under phone information, what is listed as the Network type?

It is locked in GSM/WCDM/LTE auto.
above that option it should tell you the network type. it is about half way between the "run ping test" button and the "Set Preferred Network type" option. Need to know what it says there.
Oh ok I see what you mean, it says HSDPA
make sure that you are in a active LTE area. toggle the radio off and on. the network type should change to LTE if it is available. remember that if you make a phone call your phone will drop back to just 4g/3g and it might take a second for it to switch back to LTE.
I live in Los Angeles so I'm like in the center of the LTE center in Southern California. But for some reason my phone won't get anything higher than 3G, and my actual cellphone reception toggles on and off randomly too.
It worked before. For the first 3 days atleast. And now all of the sudden it wouldn't work, so I rooted it and installed a custom ROM
Try one of WildChilds custom ROMS. LTE works on both and they're tailored to US users.

if the problem arised before you rooted and rom'd the phone I doubt the rom is the problem. there is always the chance that you have a bad radio.

That's what I'm thinking... What would I do about this?
i would verify your sim with another 4gLTE phone and vice versa.
Hrm... So it could be a Sim card problem eh? Unfortunately there are no other LTE devices for me to get a hold of... Would this be the only way?
it could be. i hope you have pulled battery/sim and then rebooted already. you can verify your phone with a known good sim and verify your sim with a known good phone. I would try your local at&t store. they might be able to help.

[Q] Bionic on GSM in India - Tata Docmo

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!
Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.
Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?
I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!

Hmmm..I just exchanged my silver for a black one and also cannot get 4g. My wife has one and hers gets it just fine. My old one did as well. I have checked all the setting suggested above and still nada. Seems this one is going back as well.
I'm on my 2nd HTC one and it operates the same as my 1st one.. In the dock of my car it connects to 4G just fine..with in a few seconds of handling the phone it drops to 3G..It works fine in great signal areas but on the out skirts of an LTE tower it just won't hold 4G..

Im in the same boat. Seems like 4g is HORRIBLE with this phone. Had the Note 2 and wife has GS4 both pick up 4g no problem, but the One picks up 4g for couple seconds then drops off completely. Yes, I tested this in the same areas.
really bummed out cuz I got the phone used so i can't return it. Love the phone, but its useless if i can't get 4g because Sprint's 3g is so slow its unusable.

Well I just exchanged my black and went back to silver and still the same issue. I am starting to think the guy that set up my phone on my account jacked something up. I have been all through the service provisioning matching it to my friend that has one....and only found one difference. Seems my phone is only picking up CDMA-EVDO Rev-a instead of CDMA - eHRPD. When I change the prefered network from LTE/CDMA it will try to connect to eHRPD but then switches back to EVDO and no 4G. So I will try to call sprint and have them inspect my account as I have not seen a way in the service programming to force eHRPD. It would be nice to have the others that are having this issue check the Mobile network type as well and see what they are running.
Try not touching the phone and see that it holds 4G until you touch it...I know its pretty useless to not be able to touch your phone but this has been my experience.
In my experience, not touching the phone does not seem to fix the problem. I do notice a small signal loss if I have the left side of the phone against the palm of my hand. The real issue here seems to be related to the phone having some sort of broken threshold from when to switch to 3g to 4g and how much better the 3g signal has to be in order to decide to switch off of 4g to 3g.
I noticed that the LTE Scan Time is set way higher than what the EVO LTE is set to with latest firmware (300 on the HTC One vs 5 on the EVO LTE). I have not had much time to test changing this to see if it makes a real difference or not though. You can check what your LTE scan time is set to in ##3282#. You will need to get your MSL to change it if you want to do that (there is a method to get your MSL without rooting here on XDA).
Another thing you can try to see if it is indeed a reception problem or a problem with the phone not switching between 3G and 4G smartly is to set the phone to LTE / CDMA(1xRTT) only. You can do this in *#*#4636#*#* under the phone information submenu. Tap where it says "CDMA + LTE/EvDo auto" and change it to "LTE, CDMA" or even "LTE only".

In my experience, not touching the phone does not seem to fix the problem. I do notice a small signal loss if I have the left side of the phone against the palm of my hand. The real issue here seems to be related to the phone having some sort of broken threshold from when to switch to 3g to 4g and how much better the 3g signal has to be in order to decide to switch off of 4g to 3g.
I noticed that the LTE Scan Time is set way higher than what the EVO LTE is set to with latest firmware (300 on the HTC One vs 5 on the EVO LTE). I have not had much time to test changing this to see if it makes a real difference or not though. You can check what your LTE scan time is set to in ##3282#.

Issue resolved for me! After 6 phone exchanges I was able to uncover what was causing the phone to not get on eHRPD which is Sprints upgraded software on the towers. I called sprint support and made them verify my UICC ID under about/phone identity, this also is the same as number as the SIM id. They did not match what was on my account. I went back to Best Buy and they called activation's and they sent a profile update with the correct SIM and UICC ID and it solved the issue. No more 104 data issues and I can get 4G now. WOO HOO!
I do want to say that Sprint really went to bat for me to get this resolved. I have to say thanks to the San Diego Sprint rep who kept in touch with me through out all of this.....Thank you man!!!

I had the exact same problem. My phone will not connect to 4G LTE. I have a few questions. How do I know the UICC ID, SIM? Where do I find them under my account?
Thanks a lot

You have to call sprint customer care to have them verify what you have on your phone. I recommend calling from some other phone when you call though. Just explain that you are having issues with your data and you heard that sometimes the UUIC ID/SIM ID are incorrect. They might come back and tell you, "well thats for international only" but in fact the SIM ID is used for LTE from what I found out. Just insist (nicely) that you just want to try it.
On the phone you can see your SIM ID under settings/about/Phone Identity.
One way to see if this fixes the issue is look under settings/about/Network and look under Mobil Network Type. If it is always running in EvDo rev A. then you have the issue if the towers in your area have Network Vision updated towers.
Hope this helps...PM me if you want more information. I can also get you tower data in your area if you would like.
slayer69, Thank you so much for your quick response. My phone runs with EHRPD when it showed 3G, not rev. A. However, my phone had the same issue, not connecting to 4G/LTE. From time to time, it will show 4G signal on the bar. However, when I tried to use it, it will switch back to 3G. I will call sprint to verify if tI have the sim card issue.

I talked with Sprint. It seemed that my SIM/UICC code is matched with the system. So my problem is still not resolved. I used an app to check the signal information, which showed that I have -70dB LTE signal. However, I just can't connect to LTE.
It seems that it is not only me. Check this link

Thanks to all in this thread. I had the same problem while in Oakland. My wife has an S2 on sprint and she had a strong 4g connection and mine was stuck on 3g. Now if this is a hardware issue that this phone has what if anything can we do. Can we exchange for a different device
