My Nexus was on 5.0.41, all working sweet, then it stopped "finding" the network. No update, flashing or anything was done prior to the problem.
I tried a SIM from another provider, but still - the "No Service" is written on screen, and when I try to search for networks, it says "Error searching for networks".
I then tried the following ideas (nothing helped):
- Reflashed the Radio image.
- downgraded the Radio image.
- Upgraded it again.
- Flashed the Stock ROM (unrooted and rooted).
- Flashed CM5053.
All was done with wipes as needed.
Any suggestions will be more than welcomed!
Can the device just get bricked like that? with no reason?
It sometimes identifies the SIM's provider (Orange for example) but always with No Service.
It sounds like your SIM card slot isn't holding the card in tight enough to make full contact... try putting a business card, cut down to size, between the SIM and the phone's frame (note, not the contacts side, but the back side) to force the SIM down onto the reader tighter.
If that does nothing, not sure what to tell you?
it didn't help
I'm Italian and I have the same your problem .. I only work in 2G GSM'...ve tried to see if you do so?
I opened another tread here Forum
You need a new SIM.
I just had this problem on Friday. The SIM some how falls of the network and your provider network will not allow it to reconnect.
I can't remember, but if I am right Orange is owned/owns by T-Mobile. Hence they have the same network.
The puzzling part about this is why it happens. This is the second SIM I have gone through with my N1, I also had one go with my G1, my sister bought that G1 and the SIM went out again. My mom bought her G1 same day as me and hers has died once. My friend has a MT3G and his has died two times now. I find this extremely annoying.
I tried every suggestion on the internet for repairing or troubleshooting a SIM. It is a waste of time. Well, everything short of dropping it in isoproply alcohol to clean the contact.
I tried a 2G and a 3G SIM on mine, and had the same result, so my problem is different.
My device just doesn't register with the network, no matter what provider or SIM generation I choose.
Can I ask for a RMA if I unlocked the bootloader?
I do not know you definitely do not pass it under warranty
Ryan then you say you clean the contacts of the nexus or the sim with isopropyl
Mine is now doing that as well and so far everything that I tried isn't fixing it. I get it to connect briefly with edge and then nothing. I am going to try a new sim tonight after work and see if that helps, otherwise unsure of what to do after that...anybody got any answers or suggestions?
I've been suffering from this... have an RMA coming but I got mine to work. Make sure you also have CDMA preferred on there or whatever the default is. If it says unknown you have to reboot the radio somehow. I pulled my battery, waited 5-10 seconds. Then i went and checked airplane mode on and off. Then i checked the service menu again. I can't remember if i had to pull the battery another time but it came back from "unknown" to cdma preferred. You can also try turning the radio on and off via the service menu. Finally select your radio bands for your region by pressing the menu button under phone information again in the service menu and select radio bands. I'm not sure if automatic is a good or bad idea but it couldn't hurt testing it if you still have some issues even after selecting your region specific bands. After this you should be able to maybe search and register or you may need to turn the radio on and off again via airplane or the service menu. I played around with it alot to get it running again.
Also I'm tmobile usa using the one for t-mobile bands. I'm not sure if CDMA preferred is a world wide setting or if its gsm or something else.. but the bands are specific to your region definitely.
a quick history of what I've done so far
Sumsung I897 captivate from ATT unlock and being used on Telus network was working great for about 4 days, then all kinds of problem started cropping up.
Phone came unlocked, I rooted using update.zip from xda, installed rom manager and started removing ATT bloatware, entered SMS and APN info which worked fine.
Yesterday I noticed that where I once got good reception I was now getting nothing and would have to drive down the street before I would get something descent. I thought maybe I'd put it back to stock with rom manager and see if that would help which it did not. It actually made it worse, decided to go all out and use the Odin3 one click downloader just to make sure I was back to stock firmware. This didn't work either but now I can enter the SMS and change the preferred network type but it doesn't save. Preferred network type is grayed out and even though I can change it it never save same as SMS.
Now I can't hold connecting in my living room where my wifes Milestone gets full bars. I tried taking the phone to where I had the best signal and change the preferred network, SMS, and set the network operator but it doesn't save any info, can't find on operator half the time on manual or auto and gave me an error and logged it to #*9900#
I've been at this for 2 days straight and can't figure out how to get it right back to stock, it seems to keep hanging onto the same preferred network and not saving anything I enter.
What can I do to get back to stock, and it has to be something that wipes everything clean, clean, clean, because even the GSM disconnects stay logged under *#*#4636#*#*
***I desperately even tried pulling the batt and SIM card for the night in hopes that would do something.
So, if I'm understand what happened correctly, you bought an unlocked Captivate, rooted it, deleted some bloatware, entered your Telus APN info and everything worked awesome for about four days. Now everything has gone down the hole. Is that right?
If that is the case, then we need to figure out what changed. Using Odin3 would have definitely put you back to stock/unrooted your phone, I don't think you could go back any further than that. If I were you, I would act like I first got the phone. As in, I would do everything you did to it, as if was day one. At one point, everything worked fine. Try to recreate that. You can always look into exchanging it or perhaps Samsung customer support can give you a little more insight to what's going on. Here's the number if you want to try them out.
Samsung customer service - 1.800.726.7864
Thanks, I've gone through the process a few times today from start to finish trying to figure it out ... maybe some of the problems aren't real problems and just limitations that I didn't know where their. I've since flash with odin3+re-partion to the bone stock i897UCJF6 as in not the one click method. It loaded fine but still have the same issue, I can't set preferred network type or get it to keep the number entered into SMSC. I think if I can get passed that I'll be be one the up side of winning. I keep noticing that the log of GSM disconnects never clears or the usage statistics under *#*#4636#*# , I'm thinking its in the same area that other bad data is being held onto instead of being cleared when flash firmware or factory reset.
Is anyone able to change preferred network type? maybe I was never able to change it but I think I should be able too.
I may be wrong in assuming this but I don't think ATT is going to be interested helping me connect one of their handset that I'm trying to use on foreign network, but I could be wrong and is an open option.

used this to lock my phone to WCDMA only so that problem is solved
*** never mind posted to soon it still didn't stick after rebooting
be carefull using the service menu as I have no idea what most of this stuff does
I got the SMS service number issue fix by taking out my sim, swapping in another known working sim from the same network, setting the service number, pressing update and then swapping back. Before every time I tried to update the service number it spit out an "update error" can anybody tell where the SMS config data is stored? on the phone or sim.
The only problem I'm having now is with reception which maybe fixable if I can set the preferred network to WCDMA only. But the button for that option is a light blue colour vs other phones that I can change this setting on. Does the blue mean anything like a locked function or something that set by the firmware as unchangeable?
*** SOLUTION ***
Thank cellzealot for reiterating how to bypass the initial device/account setup wizard, as well as his and a few others' findings with the RadioComm tweaking.
All I had to do was pop my homemade Bell microSIM I cut out from my old fullsize one in, complete the steps outlined for the RadioComm patch and the four corner touch trick to bypass the setup wizard.
(Starting in the upper left corner, simply touch all four corners of the visible screen in a clockwise rotation, ie: upper left, upper right, lower right then lower left).
*** SOLUTION ***
--------------------------
Hey all, just got my D4 in the mail today and have been trying to get the GSM functionality working for a few hours. I live in Canada, bought it used from eBay and so I don't have a Verizon account, nor do I have access to anyone with one.
I had no trouble at all using RadioComm to change the 8-byte string as per the threads on this and a few other forums, but I'm still getting the "This SIM card is from an unknown source" pop-up when I click the Android to begin the initial setup of the phone... and there is no way I can find around it.
I can see the signal bars now that I have a micro SIM that I've activated with my carrier (Bell Mobility) inserted into the microSIM slot in the back of the phone, but it still doesn't want to let me boot up. The only options in the pop-up telling me about the Unknown SIM are either Emergency Call or Power Off.
Anybody have any ideas? I've tried flashing up to the 219 fastboot as well with no luck, and of course applied the RadioComm edit immediately afterwards. I have a feeling that the phone only needs to be initially setup and then I'd be able to boot it up, because as I mentioned I can see that it's getting a signal but doesn't want to let me get into the initial user setup.
(And no, I'm not a n00b. Check the Droid 3 forum... )
Forgot to mention that the eBay seller didn't include their SIM so I don't have a Verizon micro SIM card, unfortunately for me. I have a ****ty feeling that I need to have one in just for the initial device setup then I'd be able to swap it out.
Argh!
You don't need a SIM to go through the setup process. Try it without a SIM. When you've completed the process reboot with the SIM and try to change the network manually. The SIM is unknown pop-up won't go away, I can tell you that much. When I was on 215, 219 and even AOSP/AOKP the pop-up came as soon as I entered my PIN. So don't worry about that. Sometimes it took a few minutes to get a signal. Recheck with RadioComm.
I had Safestrap on my system and that worked immediately. But the non safe system would not connect. Only after a couple of days. I can't remember if this is because I modified my build.prop.
If you're willing, you could try the ICS leak. I applied it and am very happy with it. It has settings for CDMA/GSM/World. Worked right away (had to setup APN). As you may have read, updating COULD take you off the official update path. But for me it was worth it.
It won't go anywhere but the screen that says "SIM Unknown"; the only two options it provides are two buttons on the bottom of the gray screen with the aforementioned message to either go into Emergency Dialer or Power Off. It's really frustrating! If I could just get past the setup part, I know this will work.
I can see the signal bars and can receive calls and receive texts (as well as reply to them, but I can't initiate them).
It also says Bell in the notification bar.
I am pretty tempted to do what you suggested and was debating it earlier, but haven't been able to get a concrete answer: has anyone tried to flash back to .215/.219 after applying the leaked update?
Yes and you will softbrick your phone! After updating to ICS the will phone run on a new kernel. Flashing SBF with an older kernel won't work.
The only thing I can think of is boot without SIM. Then edit your build.prop (you will need root). And hope now you can click "OK" at the bottom of the Unknown SIM pop-up.
Try chaning this in build.prop, reboot and check if you're able to click OK when the pop-up appears:
ro.default_usb_mode=2
persist.ril.modem.mode=2
ro.mot.phonemode.vzwglobalphone=1
ro.telephony.gsm-routes-us-smsc=0
These are the values I changed (apart from increase heap and wifi timing). Hopefully now you can click on OK so the screen goes away.
That's the problem, though, I can't edit any files or change anything because I can't get past the setup screen. I appreciate the help though!
I've tried without a SIM inserted and it just says it needs to have one, then prompts me to either Power Off or Emergency Dial, just like the other message about the Unknown SIM.
At any point in time did you ever have a Verizon SIM card inserted in your phone? I'm really perplexed about this one.
I don't think I'm going to try flashing the ICS leak just yet, just in case. Especially if it's not presently rootable.
I'm sure I'm not the only person this has or will happen to, I bought the phone from an American owner on eBay but I live in Canada and have inserted a Canadian GSM/UMTS carrier's SIM inside.
Nobody from Canada, either with Telus, Rogers or Bell with a D4 out there that managed to get it working?
Well, I plugged away at it long enough and finally managed to get past the initial setup screen, at least into the Settings menu so I could enable adb and installing unknown apps. That's all I needed...
Eventually a Smart Actions notification popped up and actually allowed me to set up a Smart Action without going through the setup, so I just made one that inevitably let me into the Settings menu and that was all she wrote.
Weird that this was happening though. I clearly have the GSM functions working as I can make and receive calls, but the phone is acting as if it is still locked and doesn't want to operate with a non-Verizon SIM.
I'm running .219, in case anyone was wondering.
But now you're passed the screen right? So why not root and try editing the build.prop. Like I wrote, this is all I edited and was able to use the phone with and without a SIM in it.
I did have a Verizon SIM, but I took it out at some point, before I had GSM working! It took me some days to get GSM working on 215 and 219. Wouldn't work without the edited build.prop! If you're afraid of testing, install safeboot. Then flash 215, update to 219 and use that one for testing.
You can bypass the initial setup screen by touching the four corners of the screen going clockwise starting at the top left. That will allow you to use the phone normally after that, but the unknown SIM error will persist.

I knew I remember hearing that somewhere. You sir, are a lifesaver. My previously mentioned workaround was okay but this is significantly easier. Especially considering I bootlooped my phone tinkering with build.prop settings and wasn't able to luck out and get that Smart Actions popup while stuck at the initial setup screen.
Thanks a million for your help!
(You too, Die Bruine. Trust me, I'm not afraid of making build.prop tweaks, I've been at this game for a while... )
Hi all,
I am on B378 which I got OTA.
settings, more, mobile network does not open anymore.
it worked after the update, but after sometimes enable/disable data roaming, the screen closed by itself and now it is not possible to enter this submenu anymore. when i tap on "mobile network" it briefly shows "no service" in the top left corner but the menu does not open. if I tap mobile network again, the whole settings menu will close. This is a pain as I cannot enable / disable data roaming anymore.
any idea?
other wired things I notice with this version is:
-if I disable bluetooth in the settings, it gets gray and it can´t be turned back on. but it works when I activate BT from the dropdown menu
-when the phone rings, it most times shows the name of the previous caller for 3-4 rings and then switches to the actual callers name
I have the same problem. My mobile connection drops frequently since a few days. In the past I was usually a problem with the Access Points, but I can't access the Mobile Network settings anymore. If I try to use the search I can't find the subsettings like "Carrier" or "Access point names".
I'd like to avoid to do an hard reset, also because I suspect I might happen again.
I have the same problem

In the end, I had to do a hard reset. Now it's working fine.
This is fixed in the soon to be released B383. I experienced it twice but most recently refused to do a hard reset AGAIN unless i absolutely needed to get into Mobile network settings (so was still crashing)
Just updated to B383 without hard reset and it's fixed.
it just hapened again
after a hardreset which caused lots of configurations to be redone as the backup does not correctly store all the details, settings and rights... it worked for almost 2 month, then, the phone crashed while editing a photo, the photo was gone and so were many settings, 12vs24h clock, screen brightness, screen rotation, battery level in % etc
all this could be reconfigured but the "network settings does not open" problem reappeared. this is really a pain, the phone was working without trouble all the time with Android6 but with 7, this is a nighmare.
Btw the hardreset killed my SD card, which was encrypted. some time after the hardreset, it suddenly asked for the sdcard password and it did not accept my password anymore!? The only possible fix was to use an new SD...I will never encrypt it again.
Were did you get this B383 version from Esist? my phone does not find this update yet?
echo during call
I've P9 with single sim,
the other person hears himself back, (echo) during phone call. On my end its fine.
its not network issue, as I have checked with two different network SIM cards.
any help ? :crying:
I had this on b391. Factory reset resolved.
For the mobile network problem, you don't need to factory reset actually. just change the language of the device and you can access the mobile network menu again (in another language ofcourse).
Omg..this actually works for me..I had problems first with access to wf after to setting and I realize I can turn it on from the dropdown menu ,at the end I was not able to do it even that way.I restarted phone,I opened settings,changed language-and,it works!thanks..
Wow, this was really bugging me and the temporary language switch to French worked . Thanks guys!
I have the same problem with my Honor 8 unable to access mobile data to enable data roaming. Changed the language to French then Spanish and was able to connect without problem, changed back to English and unable to access. Honor helpline ( were brilliant excellent communication prompt response to my messages) after suggesting a couple of fixes has now suggested a hard reset and revert to factory settings. Having read various threads I'm not convinced this will work. Honor must be aware of this problem and I would have thought offered a fix. I think it's a software glitch. I'll try the hard reset and keep you posted.
God bless you guys, had this silly issue while I was trying to get data abroad, and doing another hard-reset was a no-go.
I am NEVER EVER buying anything from Huawei again. Got a Honor 6x one year ago that has only worked nicely for the first month... then tons of issues (slowdowns, crashes, etc.).
Hardware is good, while the software sucks.
Thank you! thank you! 100 times! I switched to Russian - and finally got this hell menu!!! when I change back to the English - I again can't get it. But anyway - at least now I know how I can turn on the roaming!
This language change solution worked in Honor 6x too. Somehow my volte settings were disabled for jio and i couldn't make or receive calls. But changed language to Hindi and then the mobile network opened and i could change the setting. But why is this happening.
Hi I am in need of some help. I will try to give as much detail as possible.
I was talking on the phone 3 days ago and suddenly my call was cut short. The signal icon at the top was greyed out and it had a little x in the bottom. I tried to figure out what happened and at first I thought the cell tower went down because I was unable to connect to 2g, 3g, LTE/4g, nothing.
Next day with my father visiting my house, I tried his phone, put in my SIM, it works, there is signal (nothing greyed out) and I see the name of the phone service at the top left "Personal". His phone with his SIM works as well. Cell towers are working fine. I put my SIM back in my phone, no signal, not able to make phone calls or receive text messages.
At this time WIFI, Whatsapp, the phone itself works. I double checked APN settings from the carriers website, everything matched. I tried rebooting the phone, reseating the chip, selecting towers automatically, manually, and read many many discussions on the web none of which helped. I decided to do a factory reset. Backed up all photos to the computer and proceeded to reset it to factory new. Put in the SIM and same problem. Oh I also in the meantime have spoken with my service provider and they do not see anything wrong on their end.
So now I proceed to restore the phone from a backup on my MI account, all apps restored. Now I try to use Whatsapp and it wants to confirm my account with a text message, that is a problem because I can't receive text messages. I went to my service provider today, they put in a store SIM with a different number and it worked, they assumed I had a faulty SIM and gave me a new SIM with my number, same problem. Now I think it has something to do with XIaomi or MIUI or my MI account. I log into my MI account from my computer and try to add my email under security and it won't let me because it needs verify my account by sending a text message to my cell which of course is not working.
I am thinking of rooting the phone but I imagine I will somehow be blocked there too.
What happened to my phone?
Is my account being protected in some way MIUI, XIaomi or my MI account preventing me from activating my SIM?
Everything I try to do requires a confirmation text.
I want to root the phone but in order to do so I need to request that Xiaomi unlock the bootloader which will require a text message which of course is to be sent to my phone that wont connect to the cell tower.
Was I hacked or spoofed?
How do I go about fixing my situation?
Have you tried changing region and changing back to your country again? That may be possible reason.
For confirmation of code for bootloader unlocking, while applying put your sim card into other phone and that way you'll be able to get code and bootloader unlocked and can flash and try with different rom.
Similarly if your device is out of warranty then you may want to check with the antenna cable inside phone if that is got disconnected or got loosen. I don't if this would have happened or not but this could be issue. Process with precaution if you do so,I won't be responsible for anything.
