Nexus One network issue

Hi, i was using CM7 for a week, then suddenly, the mobile network begin to be freaky, cant stay on a network, cant make call and anything, I already cheked the apn settings and everything..
also switched to wcdma prefferred, to gsm only, or to wcdma sometime got signal, but after 1 or 2 minutes, cant connect to a network...
anyone can help please..

I'm having this as well ever since the update.
Gingerbread is half-baked if you ask me.

it seems to make and receive calls only in EDGE (in GSM ONLY mode), but when i change it to preferred wcdma or to wcdma only to get 3G, sometime get full signal but cant make any calls and also cant use data and sometimes got no service.. only in EDGE mode..
all this happen after using CM7 for a week... anyone please help..
baseband and radio are 32.50.0032U_5.12.00.08...
I also restore it to stock to FROYO FRF33 and the same issue, dont know what cause it..

I'm not sure it is fully related to gingerbread. I'm still using CM6 and had this issue on and off for about 3 days. It seems to have cleared up for me (knock on wood)

yess im having the same problem, i also noticed it after flashing to either honeycomb alpha or the new gingerbread update [i did both within an hour] but i cant fix this problem...:/

still cant connect to 3G, only in EDGE mode...
cant connect to a 3G network, already changed the radio to 5.08, 5.12 and downgrade it to 4.06 and nothing...
anyone know this issue??
if I cant solve it, I might gonna sell my Nexus One..,

Network issues have nothing to do with the phone, if they're constant with different ROMs. Check with your service provider.

is not the service provider, I change the sim card to another phone, and the 3G works flawless.
Also, put another sim of other carries with the same band, changed the APN settings, and it's the same problem with 3G, only work on 2G...

In that case, 2 options:
1) Wipe and check again.
If still doesn't work -
2) Hardware failure. Use the warranty.

I've been recently (1-2 months) battling with Data problems also and I don't know what the issue is. I know it isn't my Carrier because I just spent the whole month on the phone with them and they actually sent a Guy TO MY HOUSE to test the connection. I've never had problems before until around CM7 and me switching plans (which is what I thought it was).
My problem is that it works, but data just stops and doesn't want to reconnect. I have to toggle Airplane mode or reset to jump start it. I think changing towers while driving might do this too.
I've done the same tests. Changed Sim, Swapped Sims, etc. EDGE seems to be stable for me but 3G is wonky. I've flashed a PASSIMG and started from scratch that way back to root and CM7. I've downgraded my HBoot and reupgraded it. I've wiped and changed radio versions.
Right now I plan to swap to a few other Gingerbread roms and see if that fixes it. My N1 being my only internet connection it is hard to download other custom roms but I grabbed a few from work and put on my SD card.
I'm not blaming CM7 but at this point I'm really thinking about changing phones.

Ive read that there are issues with the Nexus One gps. Is this true and if so, what issues have you experienced?
PS. GPS doesnt have anything to do with the carrier does it?

well... my nexus already have 1 year, I'll sell it in a very cheap price, and buy the INSPIRE 4G and root it...
thx for your help guys..

[Q] Data connection problem .

I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

No, I have read about that today , but as a solution for a samsung g3 . I will try in the morning, because after the restart it works perfectly all day . Do you think it is a software problem?

Are you using different charger and cable or the originals that came with the phone?

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .

After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.

my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here

Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?

I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.

I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe
https://db.tt/9iMHIZvm

issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...

Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.

Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!

potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.

[Q] Samsung S4 I9506 - Not registred on network problem

My S4 I9506 is unlocked for all sim cards. I had no problems and it connected to my mobile network with problems. I updated to 4.4.2 KK and there I got problems.
When I enter my pin code, my phone wont connect to my mobile network. It says "mobile network misses" or " Not registred on network" etc. Sometimes about 50% chance of turning off and turning on, it connects to the mobile network for like 1 day and goes again. Then I have to switch and try it before it connects again..
NOTE!
- I have tried factory reset
- There is no SIM CARD problem, I tried mine on other phones like iPhone and my friends S4.
- I have tried to update firmware and install new firmware.
- I cleaned cache.
This seems to be no "inside mobile" problem because it sometimes connects for 1 day.
When im on mobile networks and get option to switch between LTE/WCDMA/GSM etc to another like WCDMA/GSM, it connects to it like 5 seconds and dissapear again and gets "Not registred on network"
There is no problem with the phone inside I believe, but something with firmware?
Any help please, appreciate that.

Hi ,
As i can see it from here after all you have done , there are two posibilities
the sim caddy
or problems in your EFS folder, did you checked your imei *#06# in your dialer , does it match , the one under the battery? even if it does it may be still something wrong with your efs,I had a similar problem and it was the EFS , do you have an EFS backup?

i have exactly same problem. im on 4.4.2 and cant make calls , or receive. not registered in network.
when register sometimes. it only works data 3g , 4g.
AP I9506XXUCNG3
CP I9506XXUCNF3
CSC I9506NEECNG3
my carrier is orange spain
please help to solve my problem.

The IMEI is exactly like the one under my battery. How do I fix with EFS? Thank You.

I know, it connects sometimes, but its a very low chance and it works like 1 day and cuts off. Getting not registred on network all the time.. There is no problem wrong with the antenna, because it actually connects sometimes, but cuts off again.
My data also works, even if it is written "not registred on network" It still works! It means that it actually connects to the mobile network, but some problems force it to not connect it completely ..

Hi ,
your problem is not quite the one i had but they seem related , do you have an EFS backup?
My Imei number was good but i got no registred on network all the time after trying many diffeent things i decided to restore my EFS backup....once i did everything went back to normal
if you do not have en EFS backup you will have to go to Samsung ( is your warranty is still valid) or to a local service shop with a Z3X box or similar to fix it

I dont have EFS backup. I tried to root the phone because some forums said it may work to download ariza patch etc and now my KNOW is on 0x1, I think the warranty is out although.

Hi,
If you do not have a EFS backup your only option would be a local service center , see if they have a Z3X box or similar it can be fixed with that..
Did you try to flash stock rom again just in case? is a long shot as EFS is not included there but there is nothing to lose

Thank you! Yes of course I tried stock, still did not work. Is there no possibilities to do it at your own? There are some tools for EFS I saw on XDA etc.

Hi
The tool you see will work if you have a backup if not your best chance is a service shop with a box, it will cost you around 20 USD

No 3G signal at all, but not quite the same

Hello, first to say, im not a newb, noob, newly registered, or a guy who dont understand anything from android.
Im not posting stupid topics, or topics which answers can be found easily on internet/google/xda/forums and such.
I am running stock rom, only rooted (i used to root it only to apply some xposed settings and clear some unnessesary apps, nothing more, nothing less).
Here is the description:
My phone has no warranty, i bought it online, brand new from UK, simfree. At that point, i had no problems with the connection. i received OTA Update - about 50-60 mb, but the phone remain 4.2.2 as it was. I still had no problems with the connection. After some time, the phone was left alone inhome for a few days, may be a week, it was turned off and it was not used at all. When i got back, i inserted my sim card, and i saw it is showing only G icon, and no 3g/h/h+, nor even 2g. I live in big city with very good network coverage, so its not network problem. I dialed up the customer service (Globul Telenor Bulgaria) , explained them my problem and asked them to check if its operator's problem or sim card problem, but it is not. The sim is fine, so is the network coverage. I dont have other operator's sim card to check the phone. I tryed several possible solutions found in google/xda - turned off the phone, removed sim and battery and left that way for few hours, still have the problem, tryed to switch operators manually and register sim card to other operator then back to mine, not working. Several times reseting/ deleting APNs, switching airplane mode, data off/on, adding apns/searching for networks and all available combos, not working asked Globul Customer support to send me new settings- not working. The only obvious thing i havent tryed is the factory reset (I still need to do a backup first and dont have time to do it right now.)
In Settings- More networks - Mobile networks- Network mode i have 2 options - 2g/3g auto connect and 3g Only. When I choose only 3g - i lose any signal, like there is no sim card. Reverting back to auto 2g/3g is registering my sim back to Globul network.
Then i decided to root my phone if i can find a fix for the connection. Rooted with CF-Auto-Root thru Odin. (The 30sec Root)
Looked for some tweaks in xposed modules and settings, i couldnt find anything related to 3g. Still looking for a solution...
I repeat - my phone was completely stock and non-rooted when the problem occurs! Now is rooted with stock rom. (this is the diffirent from every topic i searched.)
Im attaching some screenshots, if someone can help me. 2g is really annoying and slow as hell.

Well the first thing I would do is update your phone. You are running 4.2.2 which is old. Update to the latest version, that could either be a stock rom or a custom rom.
After that do a factory reset. Make sure you backup your internal storage etc, because it will wipe it clean.

Factory reset, updated to 4,3, after that 4.4.2 problem still persists.
No 3g at all. Its not the sim. Any way to fix it ?

Soo no way to fix it? Should i give it for repair?

Phone shows network but no data connection or calls possible

I have purchased a used Note 4. It was already rooted so i went ahead and installed Nameless ROM and the appropriate bootloader_modem.
Now, i have no data connection and can't make any calls. Even if the bars show that there is coverage. WiFi works fine.
My first idea was to revert it to stock so i downloaded the N910GDTU1COJ3_N910GXSA1COJ3_XSA stock rom and flashed it in Odin. Full wipe and cahce clean after the flash.
I am still facing the same problem that the phone doesn't have data or voice service. Any ideas what else to try or what could be the problem?
TIA

Anyone?

for me...i always lost signal... i dont know why...910f

Same issue
Went back to stock ROM a few months ago, but this has just started with me. 4 days and not able to connect to any data service.
Tried new Sim and manual network selection, just refuses.

Hi @dosada, i guess I.have the same problem as you, I can't connect to any 3G or 4G anymore. Now, I only can use 2G and Wi-Fi. so try to put network mode to 2G only, because if you put network mode in 4g or 3g or 4g/3g/2g automatic or 3g/2g automatic you will always end with Emergency calls only or no service. I already asked help for that but no one can solve it. I already tried everything I know but no way, no one can solve it. So just courage and let us know if you get solution somewhere.
I think that it is the last time that I use or buy a Samsung phone, they really suck recently. it's better to spend our money to buy other phone than Samsung, they lost the trust of their customers. They were number one but now...puffff...
