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..

Can't make or recieve calls though 4g works fine.

Hey, my name is Chris, i'm from Greece and I recently got a Huawei p8 lite ale l21 and i can't make or receive any calls. When I trying call someone i get a "mobile network not available". In dual sim setting i can see my sim working in slot 1 and i have full signal and 4G perfectly working all the time. Also slot 2 is totally useless as when i tried to place my sim there i did not have even signal.
I have searched around the web a little bit but i have not find something really helpful. Any ideas?
It will be helpful to change my ROM to a custom?My current version is C432B170. That was the first thing that i thought but i m not very familiar with that kind of stuff
Edit: I ve install marshmallow 6.0. Nothing changed... Still have 4g, full signal etc but i can't make or receive calls.

Anyone?

I was experiencing with similar problems, although the calls were coming through just fine, but after dialing any number, or trying to call from Contacts, the Dialer force closed immediately.
I disabled all installed xposed extension, and my problem was fixed all the sudden after the reboot, and calling works fine since then.
Your problem seems different from mine, maybe you should try swapping the two cards, or try to get them replaced at your carrier.
Also, the ROM has to be dual-sim in order to get the second slot working, and the second slot will work only with 2G and calling.

same problem here...any luck ? :\

Hi there
I had the same problem as daviddosa. Except, even I have disabled then uninstalled all exposed module, the symptom still appearing randomly. Now after several reboots and factory reset I could not start calling. Maybe I going to reinstall a stock ROM.

[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Try my APN settings to see if it helps, but locations very important

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!

It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.

I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.

Having the same issue with radio. Just replied to your post, Kalash.

Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.

Very weird signal problems....

Hi all, tearing my hair out here and can't find an answer anywhere about my issue... Basically my. Phone displays emergency calls only,even though I have signal. My cellular data is gone. I have found that if I select 3g only my data and signal comes back and all works fine again. As soon as I select lte 4g the emergency calls only starts again and I can't use my phone. Phone was rooted and working fine. I have reset to factory settings today and then set my phone up again(which resulted in me losing all my documents and photos as I could not back it up...) problem still there though. I'm. Gutted as I've only had the phone a couple of months. Please if someone could help me out here.

Have you consider that it can also be from your network provider

I haven't really as it seems to work ok with 3G. Seems more software or hardware. Was hoping someone had seen this before?!

Urgent : Unlocked at&t s7 No Signal at all; sim slot/antennae fine

Hi guys,
Been into android modification since 7 years but gave up since my last 2 phones. So i got this unlocked at&t galaxy s7 in uae and it worked like charm, the network and coverage. I then started usingthe phone in pakistan too and it worked well even here. So one day i connected to gear vr so that i can initiate the oculus data installation as first time setup but the gear vr kept on disconnecting automatically. I have used it before too but never had problem. Then i rebooted the phone and i find that i have no signals at all even though my sim contacts are being displayed and there is no “no sim” message on statusbar even. But dont have any signals at all. I then inserted my sim to iphone and it was working perfect. Then i inserted different carriers sims to s7 but yet they werent working even. I then cleared the cache, factory reset, cleaned the sim slot and the sim , but no success. I left ky ohone turned off for days andeven drained battery 100% many times to calibrate and perform hardware reset but no success. I then sent the phone back to uae for repairing from my friend as i thought that the antennae were the one’s responsible but before he even thought of disassembling the ohone, he inserted uae sim and it worked perfectly. Call and data were working perfectly. Any idea what is the problem? Kindly let me know pleaseeee. Is there any problem with frequency? Like gsm or cdma? But the phone worked before. I tried to enter the settings of manually selecting networks but there was error popup “No service and signal”. Signal strength 0asu -113dvm

Forgot to tell, my phone has never been rooted, i even tried to enable/disable “Enable hd LTE features” but no luck. Its on 7.0. Dont recieve OTA. Not blacklisted either. Pakistan doesnt have CDMA. I have even noticed it recieving weak signals compared to my iphone when the phone was working ok. And my radio is showing to be off and when i turn it on from the dial code menu. It doesnt keep turned on and it turns off automatically. I still have the imei amd baseband version. Dunno what the issue is.

Kindly reply guys
Please help

Manually enter your carriers information you'll have to ask them or look it up online sure its easy to find they might even help you in store
Its not good for you to buy these US phones outside of the US because changing CSC to INS/INU/PAK could prove to be difficult being it was never supported by snapdragon G930A model but only exynos G930F although it's not impossible
/system/csc/others.xml is where your answers are waiting for you unless you update to oreo then it'll be in /system/omc/cscfeature.xml and cscfeature_network.xml
You will need a root file manger to be able to see what I'm talking about then you will have to figure out what those "strings" mean
Unless you want to mod and figure out make your phone awesome just flash other US firmware that uses gsm network only i think ATT only uses gsm and you can root to debloat ect.
Here's a method for rooting
https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616/amp/
I'm sure there's people in your surrounding area that are into androids and rooting that understand and can help you figure things out if you know any one woth a G930F/G935F INS/INU/PAK thatd be awesome. If your imei number is truly gone from your phone its should still be on the back of the phone
I know this isn't the best help but you aren't the first post I've seen of Pakistanian with US S7 tryjng to figure it out.. idk if he ever did but if you learn you can help others as well
*note: when I say change csc I don't mean flashing firmware in odin, that is impossible. I mean porting it yourself with root like in the link below this one
*another note: I am not saying use the link below as anything other than an example because again that link was developed for Eynos phones and not your snapdragon so it probably wouldn't work but just so you have an idea of csc
