Nexus 4 No service

Hi, My Nexus 4 got no service already 1 week++. I already tested with the other SIM card and I also do a research on Internet. On Internet, also got many people faced this problem. On Internet, many people said the nexus 4 cant accept the SIM card that is normal SIM card cut into micro SIM card, must use the original micro SIM card. I also try with the solution and I bought a SIM card that is original SIM card but the micro SIM card also doesn't work. All the SIM card are cant detected by he nexus 4, will the Sim Card tray broken. My phone are protected by cover since day one and never dropped into water. I wish LG can fix this problem and help me to fix this problem, this really cause me a lot of problem. Regards, Tang.

For what its worth
I cut my micro sim ( with a punch ) and it works fine

check in settings if you have a baseband installed sometimes it uninstalls by itself so that could be the problem

Hi, thanks for reply.
Where to check, in setting app? Or Installed apps?

Settings > About phone > Baseband version
Does the phone ask you to insert SIM, or are you unable to connect to your cell provider?
If you are asked to insert SIM, you may have a bad SIM slot (broken pin contacts), or the SIM is placed incorrectly in the slot.
If you just have no service, check your phone number is displayed correctly in "About phone" and try to scan for available networks in:
Settings > Wireless & networks (more) > Mobile networks > Network operators
then use "Choose automatically"

Will the sim tray broken. My nexus 4 is running JB Stock and no root.

Had the exact same problem. Had no service at all (the network icon was just a triangle), no baseband, no IMEI. This is what I tried so far. My phone was stock 4.3 before my experiments :
1. Tried toggling *#*#4636#*#*, tried all the options there - no luck. Radio was "off", and no matter how many times I tried to click on Turn On Radio, it wouldnt start
2. Tried switching Sim cards, from same operator and from a different operator, no luck
3. Did a factory reset using the settings menu - no change
4. Finally, rooted the phone using http://forum.xda-developers.com/showthread.php?t=2010312 (First time ever, complete noob here). Everything went smoothly. Installed all the standard stuff from the 4.3 image.
Now, I could see the radio intermittently turn on and off - what a relief ! Atleast I knew there exists a chance this is not a hardware issue. I was getting service for 10 seconds, then it was going off for 10 seconds. This was happening continuously.
5. Tried *#*#4636#*#* and toggling all options again, (even GSM only, WDCMA only, preferred etc). I am in India and using Idea Cellular.
6. Searched like crazy on the xda forum for possible solutions - decided I'll try out a different radio version (I had 0.84 on mine) from here : http://forum.xda-developers.com/showthread.php?t=2087227 - If you're a complete noob like me and dont know what the hell I'm talking about, trust me, flashing a radio is not that difficult. Just refer to my earlier thread link
7. Tried flashing each and every radio from 0.24 - 0.84. Mixed results. Except for 0.83 and 0.84 all other radios atleast maintain signal throughout. However it never turns "blue" - I cannot access the internet from my phone - I have a data plan, the apn information is correct and every other setting is proper (airplane mode off, data on etc). The other odd thing is I can call and receive calls, however there is absolutely no audio !
By elimination - I think there are only two options here - either this has something to do with the 4.3 update altogether, or this is a hardware glitch on the nexus 4 which is activated by some unique sequence of steps. Please note I did NOTHING "illegal" on the phone before this problem - no rooting no custom software, not even any apps which mainstream users would call "shady" - just the usual FB, Mail apps, my corporate mail account.
Any ideas here - I am going to go ahead and try flashing my phone back to stock 4.2.2 again, and hope that works !! Please help ! And apologies for the tremendously long post first up

i recently buy a nexus 4 from ebay, only for nostalgia, so, when i receive the cellphone, i turn on without a sim inside, connected to wifi and the phone request for 3 upgrades of security, the nexus was in 5.1.1, the last than ir support, so i accepted the upgrades and the nighmare start, when i put my sim, the nexus not recognized it, i try everything, put in airplane mode and back and nothing, full reset from recovery twice and nothing.
So, i unlock the bootloader, install a recovery (clockwork) and root, after download from google the formware 4.4.4 for nexus 4, start the downgrade, when my nexus wake up in kitkat with my at&t (mexico) sim inside, the same problem, still not detecting simcard, i connect to wifi and the cellphone request for an upgrade, android 5.0.1 , click in next and the nexus start downloading and installing the upgrade, after 15 minutes, again with the sim indide, wake up with lollipop and the signal come back again ¡¡¡¡¡¡¡
My nexus after 24hrs is still with signal, whitout problems, but still request for the other 3 upgrades ( android 5.1.1 and other two upgrades for security), but with previous experience.... i will keep in 5.0.1......

S4 I9505 no 3G but only G

hello all
bought the second hand phone with this network issue.
after trying some roms, wifi fixes, network fixes, root settings, finally stopped on pyrana rom but during all those, couldnt find out what could be the reason for the mobile network.
and also realized that the imei number is not same as behind, could that be the reason? any chance to change that? or any tips to get 3G?
using tele2 in Holland, used my sim in another phone, 3G working
also used another sim from Tmobile in this phone, again only G no 3G.
thanks from now

Goto Settings, tap the Connections tab, goto More Networks, then tap on Mobile Networks. What does your Network Mode say?
Are you on GSM only or are you on either LTE/WCDMA/GSN (Auto connect) or WCDMA/GSM (Auto connect)?
If you're on WCDMA, it could possibly be an access point problem, or maybe a modem issue?

thanks for trying to help man. im on lte/wcdma/gsm auto...
just flashed to omega v28 4.4.2 but again no luck... still only G

Have you checked your APN? Is it set up correctly?
Where it says More Networks, tap on Access Point Names and check yours is set up correctly.
You should be able to find the APN details online through google

yep.. did that auto, manual, copying from another phone, didnt work. and the imei is still diffrent than the one behind the phone. still thinking that could cause the problem. :/

i wish i could do that just as easy as you say

Looking on Google, it seems some people have had a bit of luck with this issue after doing a Manual Roam.
That involves going into Settings, More Networks, Mobile Networks then tap Network Operators. Wait for it to scan and then choose another network to try and connect too. It'll fail. Then go back and do it again, but this time select your network operator and it'll connect.
It's worth a try?

Did you say that the IMEI number shown in Android is different than the one printed behind the battery?
If so, that says to me that the phone was once reported stolen at one point, blacklisted and someone has changed the IMEI number to get it off the blacklist and back on the network.

Well, the IMEI number behind the battery will be the phones proper IMEI number.
I think the only way you'll find out if it's been reported stolen is to contact your network and give them the IMEI on the phone (behind the battery) and ask them. Or you could pay for an online check. I'm sure theres a few companies that offer online checks. Keep in mind if the original IMEI is blacklisted, you won't be able to get it removed. Only the person who reported it stolen, and can provide proof it was theirs when it was reported can get it removed.
I'm not too sure how you'd go about changing it back to it's original IMEI, but if the original IMEI has been blacklisted, then as soon as you do change it back, you won't be able to use your phone at all. All data/voice services will stop working.

i checked the imei writing in the phone, and here is the result
imei.info/phonedatabase/2500-sony-ericsson-k530/ (copy paste pls. i cant send the link because im new here)
i actualy have a sony ericson which i didnt know
maybe the provider is seeing my phone as sony ericson, and that phone doesnt support 3G... hmmm now i have to find a way to change the imei.
if its reported, then i come back to this

That's your problem right there. Your phone has likely been reported stolen in the past and someone has changed the IMEI to allow it back on the network.
It's possible that the phone who's IMEI has been taken doesn't support 3G so network isn't providing it to your phone.

Problems with galaxy s5 network

Hello guys! long time lurker, first time poster here.
I have a galaxy s5
recently the phone acted extremely weird when i first used it. So i flashed the phone and re-installed the android software which fixed all the weird problems i was having.
Now im still having 1 problem. with my SIM card installed i have full network (5 bars) when i try to make a phone call i get a "not registered on network" error. I remove my SIM card, the network is still present (5 bars)
I seem to have full signal at all times with or without my SIM card. The phone does not acknowledge the SIM when i put the SIM card in or when i remove it.
Did i do something wrong when i flashed my phone? i installed the same stock ROM that was on the phone with the proper carrier (videotron)
I need your help!
Thank you in advance.

i forgot to mention that the phone is rooted. If i could somehow figure out how to reset the carrier settings i think it might help.

have you tried going into settings, Mobile Networks, and then Network search? and let it sit and pick your own network? do you have another active sim you could maybe try?

Thanks for the reply.
I've tried selecting my own network manually serveral times with 2 different SIM cards.. It didn't change anything. I still have full service without a SIM card.

Maybe you flashed a wrong modem for your area, try to flash the right and newest modem for your area. If that takes no effect, contact your service provider.

[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.

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

Radio off / no network - LG-H990DS - do I have any options?

Hello,
Hoping someone may be able to help me
So this morning I lost the ability to make voice calls and use mobile data on my LG V20 (H990DS variant - totally stock). In the top right-hand corner where it shows the mobile network strength I have an empty box with an X in the top corner. Everything else on the phone is working hunky dory. Strange as the phone is stock and this didn't happen after an update, etc. Obviously it could be a hardware failure but I'd like to rule out it being a software problem as I really quite like the phone!
The phone knows a SIM card is installed as it knows the IMEI, APN settings etc. However it just won't connect to a network. I've checked the settings and the service state is set to "radio off" and the mobile network state is "disconnected" which makes sense given I can't get onto a mobile network.
Question is how do I turn the radio back on? I've tried what I think is the obvious stuff:
1) Removed the battery, left off for a couple of mins and rebooted (hoping it will then rescan and find the network) - no change
2) Factory reset - no change
Given I have the H990DS variant do I have an options? I say that as I thought this variant wasn't particular friendly in terms of flashing, ROMS, etc.
I'm a n00b but can follow instructions so if anyone has ANY advice I'd appreciate it!
Thanks muchly in advance.

Sounds like a hardware failure
Sent from my LG-H910 using XDA Labs

It could indeed be a hardware failure but I find it odd that it can read the SIM (knows the IMEI, APN settings, the number, etc) and I seem to recall when I first got the phone I had to jump through some hurdles to get the SIM to work.
Is there no way to toggle the radio on/off? I've tried *#*#4636 ... but it won't give me access to the phone information section to reset the radio here ...

did you find a fix?
