NO service plz help - Nexus 4 Q&A, Help & Troubleshooting

i have one nexus 4 purchased from Ebay. it has
4.4.2 OS STOCK,
base band M9615A-CEFWMAZM-2.0.1700.97
KERNEL 3.4.0-perf-g2cae413 WED nov 20 14:54:28 PST 2013
build number KOT49H
it has unlocked bootloader, rooted, twrp installed.
it is able to show me IMEI number in about phone and as well as on dialer *#06#
now the problem is, when i insert sim card, it show me no service and no signal in status bar.
so not able to use phone.
kindly help me

Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Did you reboot the phone after inserting the Sim card or enable airplane mode on and off?

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

already tried with no luck

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

i use following method to downgrade
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312

Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.

OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?
I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.
do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.

I got to say, your panic is not going to help. First I want you to take a deep breath, and relax. Now, in order for us to help you. We need to have more information. More specifically, the following: Do you have roo. boot loader unlocked? What carrier are you using? What ROM and kernel you're using? Is your sim good? Are you using a micro sim? What radioband you're using? Is your sim card adapter slot damaged? Is your imei bad? Now you need to put this in a detailed explanation with what you have done with your device up until the point in where your phone stopped working.
stock room,one week old device, no root or nothing similar,the phone doesn't show imei number just blank window (*#06#)

If it's stock and all you did was do an OTA upgrade to 4.2.2 have you tried talking to your carrier? Being only a week old I would use their assistance to your advantage especially if you did not unlock/root the device. (not sure how you came across the sim card, if it was sold with the phone like it was with mine at T-Mobile, or if you just got the phone and then used a sim from the carrier).
but t mobile will send nexus to repair's for a month so do not want to be w/o my phone for so long.I'd like to solve it home...

Signal lost: Mobile network type UNKNOWN:0

Have you tried to use the tool kit all in one (AIO) to bring the phone back to its original stock? If you have not, why don't you give it a try to see if that helps.

[Q] i9505 cannot register on network

Ok so here's my problem.
I have an I9505 previously with a GE custom ROM and modem version XXUEML2, everything was working fine so far, the only "strange" thing was whenever I reboot the device the Cell Network will take about 3 minutes to reconnect, and I constantly lost the 4g connection which I attributed to problems within my carrier.
So a couple days ago I re-installed my custom ROM (was having problems with the Kernel) and after it boot back I wait to my Cell Network to connect, which never happen. So I went ahead, format everything, re-install the custom ROM and no luck.
I tried everything, updating the Baseband to XXUEML6. Install the Stock ROM (which was locked, but the store where I get it unlocked it by warranty), install another Stock ROM (right now I have the I9505XXUFNC4_I9505PHNFNC1_PHN ROM) and I still cannot get signal).
Did my modem just died, or the "warranty" guys unlock my device in a wrong method. I don't think is a problem with my IMEI 'cause I still have the same as the dive box says.
Hope someone can guide me before I take it back. Thanks.

Well, when I bought the device, it was intended to be unlocked, but for a strange reason my device (only mine 'cause we bought 2 the same day) came carrier locked (MEO from Portugal) So I sent it back to warranty. After a week I get my device back "unlocked" (Same ROM, IMEI) but I notice that it was rooted, which only makes me think that they take it to a third party which unlocked the cellphone with a method that required root. I didn't care, I had signal and 3G,

There use to be possible using this guide, with the old firmwares as far as i know is not possible anymore unless you still have that firmware
http://forum.xda-developers.com/showthread.php?t=2282683
The other way is by an unlocking code ( you can buy in many places) once is unlock , stays unlock..no matter what you flash
Try something go Settings/connections / More networks/Mobile networks/ network Operator/ choose your carrier and see if it let you register, try others and see what kind of message you get

Already tried to choose my carrier, but sometimes it doesn't even appear, and when it does, connecting to it just throws and error saying "Not Registered On Network".
What I fear is that somehow they unlocked it using the Ariza patch (or other unlock method) which should not be used.
Also after digging some info, that kind of error happens when the device have been IMEI locked, which could be also a possibility given that my SIM works on any other device, but not otherwise. I will have to give a call to support service to discard this theory.

check with them , let me know what they tell you.
Ok, I have more information, typing on the dial *#0011# to get the Service Mode Menu, it says at the bottom IMEI CERTI: NA. But if y dial *#06# I get my correct IMEI, is something wrong with the EFS folder?

[Q] Sim card problem

Hello,
I bought my Note 3 mobile and decided to flash C-Rom!
At the morning of one day I flashed the rom successfully. Later I installed all apps I wanted. I have my phone rebooted a lot of times with no problem. Some time at the afternoon of the same day I pick up the phone to stare at it! I activated the LTE option and deactivate it again. This was not the first time of doing it! After that the network signal was missing! I rebooted the phone, but it doesn't ask me for a PIN any more. I used my sim at another phone and it asked for a PIN. I used another SIM at my phone but it didn't ask for a PIN.
After dialing *#06# at Dialer a popup dialog shows up. The title of this dialog is MEID and the content is B0000000!
At settings>About phone>Status> the MEID is full of zeroes but the IMEI seems OK.
At the same screen i see the following:
Network - Searcing for Service
Mobile network type - Unknown
Mobile netwok state - Disconected
Service state - Out of service
My phone number - Unknown
MIN - Unknown
PRL version - Uknown
ICCID - Unknown
Thanks everyone in advance
Very strange.... without doing anything like flashing stock or modem?????

The reason is unknown but it seems like your phone lost a valid IMEI/baseband.
Can you check the Baseband version?
Try to flash the stock firmware, or flash the baseband for your device.
The problem suddenly appeared and that's what makes me feel uncomfortable. The baseband number is N9005XXUENC2. I will try to flash whole firmware, but does anyone know how can I flash only the baseband? I don't want to stay with the original ROM!

Finally I was able to solve the problem. It is a problem with C-Rom and 4g option. I am going to write a new reply by tomorrow and also to the forum. I appreciate the help guys.
Thanks a lot
The problem is with the LTE activation/deactivation.
I am from Greece with COSMOTE provider. Here, in Greece, at the moment we have to pay an extra fee to the provider in order to have the option of using 4g. The steps as I believe are the following:
1). I am not paying this fee at the moment so I am not able to use 4g.
2). I activate 4g and immediately I deactivated it. I did not want to open it, just touching the selection at the notifications. This option is at the notifications when you slide down the notification bar using 2 fingers.
3). Then the signal goes off and I had to re-flash stock rom once again before flashing the custom rom. The problem has to do only with the signal and everything else works as charm in the C-ROM.
The C-ROM version which has this problem is this C-RoM-KK-v7.1-20140622-hlte.zip

What variant do you have according to the bootloader?
Try removing your sim card... Boot the device... And see if the mobile radio can turn on with no card installed...

Did this happen after you updated to 9.0 Pie? Because My phone (Sprint model, flashed firmware to unlock) didn't recognize mi SIM after I took the update.
Where did you buy the phone? Are you absolutely it sure it was not a Sprint phone?
Anyways, I had to flash back to an old firmware, flash a couple of modem files, and now my SIM is recognized again.
I did what this gentleman did...

sprint lock shows "invalid sim" if i'm not wrong , mine is unlocked version and i did ask sprint "i will attach their reply"
had issues calling only certain people and as someone metioned i tured off the " enhanced 4G" and it works fine now, my carrier supports it but it seems buggy...maybe need a we need "official carrier" for it tot work right.
im personally on Tmobile and everything works fine now. I guess its called HD or advanced calling that i had to disable. i attached screenshots. hope it helps someone
