[Q] Network Problems, donation for solution. - Nexus One Q&A, Help & Troubleshooting

Majorly stressing! My girlfriend just got a N1 used from amazon.
Will not connect to a mobile network, our first attempt was orange, which prompted us to install updates and we installed them (before we installed we tested calls, they didn't work)
Then when updated to 2.3 I tried my giff gaff sim, this will not work, and I have tried the giffgaffAPN app from the market (DL'd through wifi)
What doesn't work - mobile data 2G/3G
What does/has worked - Wifi and the updates downloaded without being connected to wifi! but nothing else will work!
Any help? I donate via paypal!
We are in the UK, it is possible that it could be a foreign locked version of the phone (i heard all uk Vodafone versions are unlocked). Is there a way I could test for this?

My guess you have a carrier modded version so can you do me a favor go to settings -> about phone -> build number tell me what it says. It should say either GRI40 or GRJ22 (that is if your on gingerbread, if your on froyo then it should be frf91, frg33, frg83 or frg83D) if it something that is any longueur than that then your on a carrier modded ROM so you need to use the passimg method to get back to stock (link in my sig).

it says grj22

I would give it a shot anyway because passimg solves allot of problems the only down side is that it wipes data.

are calls not working or is it just the 3g? If the former it could be a barred (stolen/lost) handset and no amount of flashing etc. will fix it.

data works, calls/texts dont!

Go to the phone dialer.

gingerbread att tab

Just flashed the new gingerbread rom. Works great but it doenst recognize my sim card or network. I have att tab. Any help to restore it?
Did you remember to download the Modem package too? That's what I'm guessing.
sent from my Galaxy Tab using Cerebral up-link
Did you flash the version with the bootloader? Any whiteline issue on boot?
No I didn't download or flash a modem do I need to? I flashed the one with the bootloader. No whiteline I noticed.
I flashed with bootloader, tried 2 different modems, and no network. wifi works. tried flashing back to stock and everything went crazy. While I was using Odin, I STUPIDLY, plugged in my Captivate to charge without thinking, causing Odin to fail and I got the "phone - ! - PC" Icon.......talked about scared! Ended up using Roto's ATT stock image and Odin to get it back running again,barely. Now I get CRAZY lines when I boot (like if you tweaked the cable to an LCD screen), can't see Recovery screen....total craziness. Still no data. so I flashed back to OverCome Gingerbread ROM following his instructions, still no data
UNTIL
I swapped the SIM card with my phone. I suddenly got data on my Tab, but data would not function on my phone. Seems like the problem follows my SIM. Background: I also had a weird issue before hand where I couldn't open the Market on Cellular data without killing the data connection on Stock Rooted.
Thought I'd share.
EDIT: oh, and I can send text messages without issue.
Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN with doesnt work with the Tab Data plan.

Well Son of B....you rock. What pisses me off is I've screwed up my boot screen (all kinds of colored lines) trying to fix this. Thanks.

Gingerbread 2.3.3 installed modem does not work
AT&T monthly pay as you go. What modem.bin do I load? Where can I get it. Is there any additional setup instructions?
Follow my instructions above and flash the JK3 modem fromt this thread.
http://forum.xda-developers.com/showthread.php?t=1069727
Mine keeps saying insert sim card to access. So how do I get it to recognize the sim?
Please anyone with some help? Can I store back to original att froyo and just wait for official upgrade?
Have you guys entered in your APN settings for ATT Broadband?
I am also having a strange radio issue. I am using an ATT Tab with Overcome v2.0 Beta 2 and the JK3 modem. 3G data works great until I try to access the Google Android Market. As soon as I do it drops the 3G connection and wont come back until I reboot it. If I dont go to the market or only go to the market on WiFi it works just fine. I also verified that the same behavior happens with the JPZ modem..
My theory is somehow ATT is blocking Gingerbread Tabs from going to the market using their SIM card. Therefore I think maybe I need to edit my build.prop to spoof them. Can anyone recommend which values should be changed? Can anyone think of anything else that could cause this? Can anyone reproduce this issue on their ATT tab?

You used the bootloader patch app, right?
Reinstall the stock 2.3, then the root, then overcome. Follow the overcome guide, this time put the modem.bin in the phone slot in odin. There is no other fox for the wiggly lines. If you don't reflash everything, you can't get into recovery mode.
i cant get into the network settings as it tells me to insert a sim. I tried to flash the modem as well with no luck.
ok so I turned on my tab to play with it a bit and I had data! It was an H and seemed to work. When I restarted the tab it stopped working and said no sim again.
1) The Gingerbread rom has a modem with it that works fine on AT&T.
2) Did you leave your sim card in while flashing?
i did leave my sim in while flashing. Should I have it out? It seems the tab only recognizes the sim card every so often. Not all the time. Any way to flash the sim recognition part?
Could you please post how you flashed your att tab so I can follow it? Thanks.

[Q] How to get mobile networks working on Milestone Cyanogenmod?

I just flashed kabaldans Cyanogenmod 7.1.4 coming from 7.1.1. Like I've done many times, changed baseband to "Venezuela - Mobilnet" in OR, updated google apps and everything.
But now my phone says "Emergency calls only", when I check the network operators option it only shows one of the three operators in my country, and the one that my phone is registered to does not show up. Ive tried reflashing the baseband 5 times but the result is the same, still can't connect to the network for calls, much less data.
EDIT: I flashed 7.1.1 and the network works just fine..
if you've tried setting Baseband, why don't you go ahead and file a bug at http :// code.google.com /p/cyanogenmod4milestone/issues (sorry, new user, can't post links...) so kabaldan/nadlabak can fix it?
I would definitely try reflashing to the newest and using openrecovery to flash the baseband onto it. I can't imagine that would have been a broken feature.

unlocked HTC Desire C no signal but Data working

Hi everyone,
I have a desire C which was originally on the 3 mobile network, I unlocked it successfully to work with other sim cards and was using it on Orange for a few months.
I have also rooted the phone following the original nameless thread & installed the nameless ROM onto it. This works fine with the ORIGINAL 3 mobile sim card but not with any other sim card. AlI get is no service showing. I cannot make or receive calls, however data works fine (with or without wifi).
I have tried the following:
turning airplane mode on and off, also usin the *#*#4636#*#* (or whatever it is!) thing to get to the test menu and turn off radio and back on again.
Wiping to factory reset
Re-installing the rom from the phones recovery "install zip from SDcard" menu, - also installed the revolution 5en5e rom
IMEI Shows the original IMEI from the phone
If I go to my available networks list it shows me the EE (orange) network, o2 Network, Vodafone network & 3 Mobile network, but no matter which one I select it says your sim card does not allow connection to this network.
I've also tried to change the way it connects from auto to manual and vice versa, but each time it says unable to connect to this network at this time, please try again later.
I just cannot get it to give me signal unless its on the orignal sim & i'm sure the signal is worse than the stock rom.
I'm assuming it's a radio issue?? only assuming as I would have though I would have the error of invalid sim/network locked etc, but I don't know enough about it really.
So currently the phone sits with the following installed:
Android Version:
4.0.3
HTC Sense Version:
4.0
Software number:
ReVoluTion 5en5e Edition v1.0
HTC SDK API Level:
4.2.1
HTC Extension Version:
HTCExtension_403_1_GA_9
Kernal Version:
3.0.16-g51cada9

I hope someone can help & if you need more information please let me know!
Kind Regards,

Try unlocking your SIM again, but while on the new Rom?
Make them boys go loco!
Hi,
I don't get the option to unlock the phone as it accepts the sim, just gives me no signal. Before I unlocked the phone it used to say something along the lines of sim card not accepted, you then had the option to put the codes in to release it from its carrier.
regards,
lee
I had the same problem with my SIM card. Phone is unlocked but one day I see that I don't have any network signal.
So I snoop around trying my friends' SIM cards on my phone and they work.
Went to the office nearby and told them what happened. They said its a malfunctioning SIM card and change it for free.
Now i didn't notice whether I have data traffic working but it resolved my signal problem. Hope this helps.
I've tried 3 different sims on organge and o2 and have the same issue
I've called three mobile (original carrier) and they advise that there is no barring or anything on my profile.
I think I will try to reflash to factory and try again.....I cant think of any other way.

Flashed boot.img & installed the "untouched__rom_v2.0eu_dcplx1" from this site and it does the same thing!
Does anyone know what else i can do?? or have a three mobile rom I can try?
Lee
Ok, managed to speak with three Tech support again, turns out my profile is not ok.
My phones imei has been blocked by........wait for it.........o2!!!!!
they are speaking with the fraud team and will hear back this week. How bizarre.
I don't understand how another network can block my imei from being on other networks apart from the original one? if it's blocked it's blocked surely....
ah well, will wait for the call back and post up with the outcome.
Lee
Spoke to three today who advise the phone is not blacklisted like they originally stated as they have spoken with O2.
They say there is nothing on my profile to block it and it should work.
I don't know where to go on this now.
Can anyone help please?

[Q] Network unavailable

Hi, Ive got xperia from vodafone australia.
When I first started my phone I upgraded it to 253 straight away. Everything was working fine, but needed root.
First I tried to open the bootloader following instructions from sony but something went wrong(bootloop) so I used the SUS for the recovery. Worked fine, and when the phone was starting for the first time it went through some network configuration.
Then I downgraded it to 434 with unbranded australian rom. Upgraded to 10.3.A.0.423, unlocked bootloader, rooted, everything was looking fine. But today in the morning I tried to use my phone and it says "network unavailable" when i try calling or that "the message couldnt be sent" when trying to text. I locked bootloader, flashed with sus, then flashed the same unbranded rom and still the same!
Emergency calls are working. Reception is full but it doesnt display "H"(wifi is off).
Is there any way to run the network configuration like it was after restoring though SUS? After flashing another roms there wasnt this kind of thing..
Anyone could help?
I flashed another rom, 10.3.A.0.432 from spain and my data connection started working(yes, im sure that wifi is off). But still I cant make a voice calll. During the basic configuration it asked me about my network and if I want to download internet settings. Is that possible that I need specific settings for Vodafone?
When I tried calling my number from another phone it just says "call ended" instead of connecting to the voicemail.
Anyone?
Try another SIM card.
Sent from my C6603 using xda app-developers app
I'tried another vodafone card, was the same. Tomorrow I will try to get card from another network but it's a bit doggy, that I got data connection but no voice calls/texts. Remember that long time ago on wm I similar problem but there I was helpful the reinstall radio and run connection settings. Is there anything like radio drivers for xperia?
on android the radio is the baseband, have you called your provider to see if there are any issues with them or your account?
What do you have in APN in your phone?
Check it in Settings => Wireless & Network => More...=> Mobile Networks => Access Point Names
If you have no APN don't search further, this is your problem, you need to fill the APN with your operator informations.
I've had exactly the same problem after réinstalling the phone with PC compagnion.

Problem phone only working in gsm only??

Hello developers.
I am amz. In dire need of your help.
Ok so i have a new mini
I turned it on n it would jus turn off if I used apps. I got a new battery. That stopped.
I then try use Internet it works only on G and E but if I go to 3g or Lte. .H will never come on. Can't call it says not registered on network only on the higher bands not gsm.. It's a 4G sim it works perfectly in my old s5 mini and signal is excellent here. I got new Internet settings too. G n E works why the he'll doesny the other bands register on network? Imei shows its not blocked either. I'm in the UK on EE. I cannot understand. I have all the OTA updates. Can u tell me if I can fix it by doing something thro service menus or anything also all sims do the same in this phone. I don't have a pc to change the rom. Could I do it through a external SD card.
Please I beg of you help.
Run the system updates, I had network issues until it was fully updated.
They are only patches, no new rom.
Reboot once each batch has completed until there are no more.
If that does not work, potentially you have a row version which uses a different band than us in the uk. Send it back.
I have the June 2015 update. I ran all updates. Still not working? I wanna install the cm12 rom m see if that'll fix it but kingroot not working. How do I see what band my phone is tryna connect in wcdma mode n what is required by the network? 4g don't work either?
I just Checked. My networked EE uses wcdma on 2100mhz. My phone is trying to connect. But it just says emerge calls only. Wth. What's wrong with it??
Can you post a screen of the About phone?
Should look identical to mine
Also, have you tried googling ee 4g settings s5 mini?
My network required me to get a 4g sim upgrade, before that it needed settings for hspda 3g which worked
I have a similar problem. Phone worked fine for couple of months, but since tuesday, it only works when I force it to GSM only.

(the thumbnail above equals to mine)
Maybe the network providers have changed 3g/4g details.
Check the website for correct details and update them in phone, if that doesn't work try a friends sim, if that doesn't work return phone
I had the problem aswell. I searched for the newest firmware in the internet (in my case I used the russian one). Then I extracted the modem file and made a tar file of it to flash it through odin. After I've done it everything worked fine.
If you want me to, I can do this tomorrow or saturday for u.
I flashed the original firmware (July 10, Nee), that did not help. What is the date of your firmware that works now?
I thinky june 2015.. I had the problem in February last year
It's me amz
Ok so basically I found out I need to flash my modem file or change the rom. But I have no PC to flash
.so I need a app which can root my phone or something without a computer. Kingroot didn't work. Anyone got any ideas on how I can do this? I've Google relentlessly. I need a developers help lol
I'll even pay them

I returned my phone and they changed the "circuit board". So mine was a hardware problem.
I've rooted my phone and going to change my rom however the tar.md5 file I can't use as I can.tell use odin. I need the .img file to have the twrp bootloader. anyone know where I can download this?
