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.

Nexus 6p - Set GSM/UMTS Band Problem [Resolved]

Hello everyone. I'm having a problem with my network after going into the test menu (*#*#4636#*#*):crying:. I'm hoping someone can help me out.
My Phone:
I have a stock Nexus 6p not rooted.
The Problem Cause:
After going into the test menu (*#*#4636#*#*). I pressed the menu button (...) and pressed the "Set GSM/UMTS Band" button. My three options were "USA Band", "Band 6" and "Band 7", decided to select "USA Band".
The Problem effect:
Since I did that, I can't make or receive phone calls. My phone won't ring (though it "rings" for the person trying to call me and they get to my voicemail). If I try to call someone else, it hangs perpetually at "dialing".
Soulution I have try:
1-Setting the bands and switch between USA,6,7 but nothing changed.
2-Doing soft/hard factory reset but also nothing changed.
Any ideas how to fix this problem?!

Factory image.

Same problem
I'm having the exact same problem. I couldn't make or receive calls out of the box. When I fiddled with the test menu, I was able to at least get it to where I could place calls but I still cannot receive them. I'm not sure what I did at this point. Verizon support and Huawei support have been useless. I tried to factory reset and that did not help.

What carrier are you with? I did the same thing but I managed to get my phone working again.

why did you mess with these settings if you don't know EXACTLY what you're doing? very big mistake. there some settings you should never fiddle with unless you're dead certain
best best now, imo, if the factory image doesnt fix it... unlock your bootloader and install a ROM that has an expanded set of radio bands... I know some ROMs have it, but not sure which ones.

Yes use Chroma it has more bands to choose from. I think someone needs to create a sticky not to mess with those settings.

I only messed with the settings because I was already not able to make or receive phone calls. Messing with the settings allowed me to at least call out now.

Flash the factory image. That way you know for sure you are as stock as could be. Then if the problem persists exchange the device because its faulty. You shouldn't have to mess with any settings to make calls. Other than maybe a borked APN setting.

:good::good::good::good:
Yep! Flashing the Chroma ROM did it! It's all back to normal now. Thank you scoobysnack soooooooooo much for your help!
what I did are;
1. Hard reset
2. Unlock bootloader
3. Install TWRP
4. Root
5. Install custom firmwares
6. Revert back to stock firmware
7. Install different 'radio' images
8. Install different stock firmwares
Unfortunately, none gave me a positive outcome.
Last Hope Was:
I flashed Chroma, a lightweight AOSP ROM focused on battery, performance and stability.
http://forum.xda-developers.com/nex...-chroma-11-08-2015-lockscreen-navbar-t3244444...
The following link is for Chroma download and installation instruction:
http://nexus6proot.com/nexus-6p-custom-roms/chroma-rom-for-nexus-6p-android-6-0-1/2/
This custom ROM for Huawei Nexus 6P was first recommended by a scoobysnack. It works with a proper selection of bands according to your country.
On the dialer, use this codes *#*#4636#*#*
Selection for different bands would then available.

I'm glad you figured it out. However, If you tried the factory image and it didn't work, that's a problem! You should have had cellular service right out of the box and definitely after you flashed the factory image. Unless you did not actually try the factory image itself. Can you clarify. Because if that's the case you have a defective unit and it will be an issue when you need to actually restore your device some day. Also don't want people to get the idea that a factory image is not a fix for this.

Flashing the factory image does not work. I messed with my phone for 4 hours trying to get of to work again. I was originally on chroma when I screwed my bands up. That's how I knew about the other bands. I believe it only fixes international phones . I'm in the US on VZW and flashed factory image and had to select band 6. So depending on where you are depends on what method you have to use to correct the problem. And yes a sticky and FAQ should be made as a lot of people seen to have this problem.

The images work on either variant. It confuses me why a factory image would not fix it but I'm sure there is a reason. Its new to me though. What's weird is I am on Verizon in the US as well. Works right out of the box for me and any issues that I have come across have been fixed by a factory image. I wonder if people having problems on Verizon are having issues due to network and sim card provisioning issues and by switching bands you are fixing it but you are not on the normal bands maybe. I know some people on Verizon had to call and tell them to activate LTE on their line even though they were supposed to be getting it. And that fixed the no service.

I guess the reason why a factory image did not fix the problem is because my phone version is US not International. And I am now not from US, originally from Middle East. So there is no compatibility between US and the international bands. The only choices I had from the Bands are USA Band, 6 and 7. I am guessing that the International version has more options and compatible with variant bands.

guys. try to install chroma rom , it has several different bands. just to get it working . then return back to stock if you want i had the same issue and i had data working and sms without calls until a guy helped me ( im very grateful for him ). i hope it works. please let me know
@scoobysnack .. man, I came to help but you were faster haha

I used Chroma ROM it gives you proper selection of bands according to your country.

Similar problem
I have the same issue and my carrier is Airtel - from India. Will Chroma work with this?

No Network

Hi good people, I am facing a problem. Around 8 hours back I tried calling someone but the call didn't connect so I restarted the phone and then I lost the network. I tried reboot, flashed different ROMs (unofficial CM14, cm13 nightly build n MM nougat backup), tried with GAPPS and without GAPPS but the problem is persisting. I even tried swapping the Sim cards before that but of no use. I tried debugging by using *#*#4636#*#* but ping test is failed and also there is "TURN RADIO ON" I believe ideally it should be "TURN RADIO OFF". please have a look at the screenshots. I'm almost dying without making important calls.
Update: Guys I have got it working.. Kindly look into my below posts. Please don't misguide people for small issues.
Thanks

In the screenshot we can also see, GSM SERVICE IS OFF. it stays the same even after clean flashing a new custom ROM.

Got it working. Flashed latest COS ROM file however the situation was still the same. Then I removed sim, switched on airplane mode restarted. After reboot inserted Sim then again restarted n then I got the signal
1. Removed Sim card, switched on airplane mode from both power menu and notification toggle.
2. Restart, inserted Sim card and switched off airplane setting from setting. (Notification toggle and power menu didn't work) then got the network.
Please note I tried with only one sim in sim 1 tray. Later I got the network for 2nd sim as well

Which rom did you flash and what was your method of flashing?
You also said simply flashing didn't work. It was what you did with reboot, aeroplane mode and taking out and reinsert the Sim that worked?

I've had the same problem for almost a month now... and i gave my phone to the service center. They called up to inform me that its a motherboard failure and they'll fix it.. I'll provide further info when I get my phone back (probably in 3-4 days)
P.S I tried almost every method to make it work. So if you couldn't make it work in first 2 days or so, dont waste your time and just give it for the servicing (make sure its in Stock OS so that they dont ask any questions about root xD )

I flashed almost every latest ROM. But no ROM got the network back. So as a last resort I flashed COS 12.1 and still didn't get the network. Then I removed both the sims, activated flight mode restarted the device, left it couple of minutes and inserted only one sim in first slot. Holla I got the network. Then everything is back to normal
If u r facing the same problem I would suggest u to activate flight mode n restart. If it doesn't work try by removing sim cards, if it still doesn't work try COS 12.1.

Usual procedure of flashing. Wipe cache, dalvik, system and data. Flash ROM + Gapps. Reboot

Try to search in the forum. There is a lot of threads with the same problem with the Zuk Z1. It is a hardware problem.

Your modem and baseband sections may be damaged. Modem structure is hidden under qualcomm structure. To Access and repair those sections, you need to do some modifications. I managed to make my Zuk Z1 worked again with some tweaking. Altering that part of the phone is illegal due to its restricted elements such as IMEI number. That's why I cannot post a tutorial here. İt is not allowed. However, I can help you if you personally contact me. I hope you get your signal back soon.

Please follow xda rules and don't tell people illegal things where they get in trouble. Keep in mind, that's not an illegal forum

Sure thing but I have already mentioned it. I didn't post anything illegal. So, take it easy.

SIM card not detected

I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.

You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.

I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.

And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.

I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.

Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.

I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.

Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.

could you detail how to do just that? Because I'm in Brazil and I have the same problem.

Sim card not recognizing

Got a tough one. Ever since last Wednesday my SIM card hasn't been recognizing like it should be. It will randomly stop working and not work again untill I flash a new rom/backup/stock. I've tried clearing the cache... Nothing. When I go into *#*#4636#*#*, if I turn of radio power, it will recognize my phone number after about 10 seconds. Also, It says that APN settings are not available for this user under APN settings... Any help is appreciated, thanks.

This only works with mediatek devices...

I have seen many posts about the sim card error, and have now experienced it myself. I have a USC XT1768 (on AT&T), running RR for about the last 4 months. Everything has worked perfectly until 3 nights ago when, suddenly, for no reason I had no service & saw there was "no sim" recognized. A Google search led me to switch to 3G and turn on airplane mode and reboot. After rebooting, I turned off airplane mode and service was restored. However, I am forced to use only 3G. After multiple "tests" switching back to 4G LTE, I always lose service. Yesterday, I "tested" again and LTE worked for about 8 hours before I got the sim card error. I re-did the airplane mode/3G process and I was back in business...just with 3G.
Last night when I got the "No Sim" error, I noticed that the preferred network in *#*#4636#*#* was "Unknown". It had been set to LTE/UMTS/Auto. It doesn't seem to make a difference if I switch it to Global, or anything else. The problem remains. Oddly, when I just entered *#*#4636#*#*, the preferred network setting was on WCDMA. Weird...I didn't select that setting.
Anyway, maybe this can kind of help someone else.

Tried the airplane mode/3g thing, still nothing for me. Just "lost" all recognition of a SIM. Nothing. No matter what I do, won't recognize. Lots online about it, loaded the latest F/W, etc., still nothing. The phone is like a new phone. Something feels hinkey about it though. Seems it's happening to unlocked Moto phones after about two-months.

I've had it for about a year when it happened, but what I did was send it to Moto and just told them it stopped working out of the blue. Flashed stock and sent it in. Within about 4 days they sent a new one. I would recommend that if you have a backup phone.

Did you have an unlocked bootloader (using the Moto code they send along with the warning that it'll void warranty)? If they still warrantied it, I'll do what you did, then sell the replacement ASAP. What an unreliable POS...

Not really. Clearly a small percentage of E4s have a SIM problem; Moto should own up to it. However, that's unlikely as they never acknowledged the HW GPS issue on the G4P line that impacts a much larger proportion of devices.

Yeah, it was unlocked but I don't know why they had still look it though..

If you erase modemst1 and 2, the SIM will be recognized again. At least, it was on my XT1768. I wrote a small TWRP flashable version, for when it happens when I'm out and about. Just boot to recovery and "install" it. It's attached to my reply.
Additionally, the following firmware build is supposed to have the fix for this issue: https://androidfilehost.com/?fid=746010030569967659
Addendum: AFAIK, all Moto E4's running a build less than NPQ26.69-64 have the SIM issue. From what I've seen, it happens when one doesn't have any signal for a few hours, then comes back into an area that has a signal.

Can you boot TWRP or another custom recovery? Need that to apply the 'fix' in the form presented. Not even sure it will work on a bootloader locked device.

Must be other variables involved. Have a much older build and frequently travel to/through areas with no coverage. Have yet to experience a SIM issue.

Your bootloader is locked, so you can't apply my fix from TWRP. You will need to hook up your phone to a computer, boot your phone to your bootloader (power + down), on your computer cd to your Android Sdk tools directory, then run "fastboot erase modemst1" and "fastboot erase modemst2", then reboot your phone.
However, you should be getting OTA updates. The most recent firmware should prevent the issue.
