Hi all,
I got a Nexus 4 from Ebay. Cellphone is in flawless condition, it probably has less than a couple of months of use. Unfortunately, I am not able to pick up a signal in any way. I just get a constant "No Service" message, and occasionally it will jump to "Emergency Calls Only".
Testing menu says Signal Strenght is 0 dBm 99 asu, no neighboring cells and location is unknown.
I've tried changing the prefered network to WCDMA only (as suggested in other threads), also tried with the other available settings with no luck. Tried playing around with the Change Bands setting as well but it makes no difference
Tried with a few different sim cards as well but that didn't work either, just got signal momentarily and but it would go on and off.
Cellphone came with 4.2.2 and I upgraded to 4.3 as requested by the system. Same issue.
Tried basebands 48 and 84.
Tried CM 10.2.
Replaced SIM card with a brand new one.
Cellphone doesn't appear to be blacklisted either.
Not sure what to do next. I'll try to get in contact with the seller but I don't expect much from him or eBay. Maybe I can sell off the device very cheap for spare parts, or send it for repair somewhere? Leave it as a dev device (which would virtually indistinguishable from a N5 that I plan to get anyway), Anyone else has any other suggestions or ideas?
Try to install a factory stock image: http://forum.xda-developers.com/showthread.php?t=2010312
If you pay with PayPal you get buyer protection so you can try to get your money back.
Could be a hardware or antenna issue.
To me it seems like its been blocked for certain reasons. Either it was reported stolen or the person who sold it to you didn't pay his/her bill for which the carrier blocked it. In that case you can't do much about it.
I would contact the seller right away. If you get no response contact paypal and eBay.

This problem is occurring for a lot of Nexus 4 users, including me. Its some sort of pandemic. Here’s what you can do to atleast restore service to your phone : flash the factory 4.3 image to your phone, again. However, try flashing a radio that is 54 or older with it. Make sure you wipe the cache and flash all the partitions, system, boot, bootloader and the old radio. This will bring back service to your phone (did for me), however you will be left with no in call audio and your phone wont connect to the internet through the mobile network, only wifi. After doing this, you will see your baseband and IMEI in the phone.
You can use this as some sort of “test” to verify if your phone really isn’t stolen. What is the ultimate resolution to this problem ? I really don’t know yet. I’ve been breaking my head over this for the past 4 days now. Maybe I’m going to try out the unbrick method mentioned over here to see if that helps.
As an update I am getting intermittent signal in some areas, but it's really spotty and only lasts a little while : (
I'll be giving different basebands a try tomorrow but I don't think it'll help much. I'll also try the full factory flash posted above.
Same problem here, had the phone for about 2-3 months, bought it off Kijiji, I tried flashing 4.2.2, went back to 4.3, flashed every baseband and still no success. The SIM works perfectly in another N4, tried a few other sim in mine and still the same results. Any other ways somebody got this fixed ?

I'm talking to the seller, see if the phone is still under warranty. My other options would be to change the antenna myself (see if it works), or resell it at loss for spare parts, or wait to see what eBay says.
Just to give you guys some hope, that this is not just a problem faced by second hand phones - My phone is bought directly from the Play store - I contacted Google service a few days back and they asked me to return the phone for a replacement. Only problem is I have to ship this back to the US (where I purchased from), since they dont provide replacement service outside the country of purchase. I'm in India now.
I've tried absolutely everything myself. Flashed many many radios, 4.3, 4.2.2, I'm only able to get it to the point where there is network coverage, I can make and receive calls but there is no in call audio, nor is there any mobile internet connectivity (Only through wifi).
Something tells me this is a problem with the latest OTA update that caused this issue - I was completely stock and everything was working properly, when this problem appeared one fine day - It started with me not able to connect to the mobile internet network for a few days, and then one fine morning, BAM. No service. It was only after this that I started flashing and re-installing stuff on my phone, desperately trying everything to get the phone back to normal again.
I think the last OTA update somehow "bricked" the radio (dont know if something like this is possible, just a noob guess). My only hope is the 4.4 update has some fix for this, else I'm going to try the unbrick method mentioned on these forums to see if that works. Only then will I take the pain to send this back to the US.
What's the unbrick method you are planning to follow?
I was considering using the unbrick method listed here : http://forum.xda-developers.com/showthread.php?t=2347060
Although I'm not completely sure it will work. Do you or anyone else have any suggestions for this ? I'm hoping 4.4 gets released ASAP, I'll download and root that as quickly as I can, hopefully Google has some resolution to this stupid problem
i have exactly the same problem
i have exactly the same problem. i bought my phone at US from Google play.
the phone worked fine for two month and then i got - No Service, and its swipe in a sec to emergency call only.
i try to replaced some sim cards, and factory reset with no success.
i also read a bug report that opened in Google : 58317
they told that there is a problem with the radio interface and radio driver at the 4.3 update, and they will fix it in 4.4 kitkat version.
i hope that 4.4 will fix this terrible problem, if not the phone is totally a door blocker..
Did anyone ever find a solution for this issue?
My friend has this problem with his Nexus 4.
I've searched A LOT and to this day (half a year later) haven't been able to find someone who reports this problem was solved.
I've also tried every suggestion I could find: flashed every stock image available, tried every combination of stock/custom ROM/recovery/radio, even tried the unbrick method mentioned above.
Nothing helps. I always get the same symptoms:
- Radios 54 and below - no in call audio.
- Radios 83 and above - Baseband unknown, IMEI / IMEI SV unknown, no cellular reception.
Also, RMA is not an option because the people at the store (a) don't know how to fix it and (b) claim the warranty doesn't cover this issue so they won't replace the device.
Any suggestions? I'm willing to try anything...
Maybe its a simple hardware failure like a loosely connected antenna? It doesn't really seem to be connected to any specific software setup
Something that happens to me rarely: when I'm in an area with very low/no reception sometimes the phone won't reconnect itself again and just stay on no reception until I reboot. Only happens like one or two times a month though.

Thanks, but I really don't think it could be an antenna issue.
I can see how a malfunctioning antenna could cause cellular reception problems, but it shouldn't affect IMEI or Baseband version readings. Those things have nothing to do with the antenna.
Also, the fact that the symptoms change with different radio firmwares says there's a big chance this is a software issue after all.
I just can't figure out what the cause is and how to eliminate it.
Flash any full factory image. If the problem persists after you can be pretty sure it's hardware. No signal for most of the time and occasionally picking it up could be something as simple as the antenna being unplugged, which can sometimes happen after a drop, or a forgetful repair.

Could be a broken or badly connected antenna. They are very fragile. Have a look at how to replace the antenna maybe?

I've opened up lots of my old phones (not my nexus 4 yet) and its normally easy to find and change as it's separate from the motherboard and looks basically like a piece of plastic!

I have the same problem no connection but the phone recognize the sim and the number of the phone. I've tryed to return to stock using a factory firmware but I'm not able to fix the problem... (this morning is working fine and my phone never fell down or something like that)
If I open btw the case and try to remove and reinsert correctly the antenna the phone will recognize the signal?

I have a tmobile wing and I had it for awhile but just started using it again recently but when i put my sim card in the phone and turn it on it just keeps saying Searching...
I get service for like 2 minutes then it would just go away. This would happen when I leave the sim in the phone, it would get service once in awhile, like for 2mins every 2-3 hours, but never consistently.
My sim card works perfectly on other phones and when i insert a friends sim card into the wing it still has the same problem, it keeps saying Searching... I don't think its a problem with the sim card since it works fine with other phones.
I tried soft reseting it and hard reseting it but it still seemed to have the same problem. Does anyone have any idea what the problem could be or what I can do to try and fix it?
what radio rom does your phone have and what rom are you using?
you can check your radio rom by going to settings>system>about ( i believe). If not that, then settings>system> device info.
also, if you don't know what rom you're using, it's probably the stock rom.
It might also be that the particular spot you are in is just unlucky for reception and that other phones have better reception by design.

It says Radio version: 02.83.90
And i believe it is the stock rom since i never changed it or anything. and I doubt it is the area because I tried using it in several other towns.

p4350
well on my p4350 over the past 2 weeks i have been receiving little signal like every 5 - 7 hours i mite get it for a bit but only for a sort time. i was wondering if it needs its radio updating?
any help?
Hi, I just want to share my story. maybe it could help you out.I had a wing for more than a year now. recently it had the same problem. it just don't have any signal at all, just keep searching. I tried what you did before. hardreset, softreset, and update the firmware. Nothing helps. since my phone is out of warranty, i can't send it to t-mobile. So i went to a local repair shop. They told me it could be hardware problem. I paid $50 to get it repair and no problem since. I don't know what they did, maybe replacing something inside. So don't just look at the software side, it could be hardware problem.
I have the exact same problem, and it's really pissing me off.

Hey there, i have a problem with my HTC Magic. I have had it in about 2 months, where it worked fine. Suddenly it couldn't get a signal to a network. When i try to connect to my network it says "Your sim-card dosen't allow a connection to this network" can anyone help me out with this? I've got HTC Sense on my mobile.
Same issue with stock Donut
I too experienced the same problem when traveling through Atlanta airport. This was a stock MyTouch Donut. After arriving at my next destination my phone worked once again.
I have initially rooted my phone today with Cyanogen latest. I am looking for the fastest ROM I can find without all the bells and whistles. After finding said such, I will be updating my radio.
I have had other strange issues with the radio on this phone. T-MO support suggested replacing the phone. However, I don't think the phone is the problem it's their lack of bug fixes.
I've got the same problem, 2 different sim cards on 2 different networks and both are showing no service and not finding any networks, but both are working in my old Nokia E65. Strangest thing, I checked my email over 3G earlier today, an hour later no service and has not changed since. Tried everything I can think of; nandroid restore, hard reset, safe mode, checked the testing menu. Only thing I haven't done is unroot and return to stock. It's funny, I always knew something would go wrong with this phone... Womans intuition maybe?
Willing to try anything that anyone has to suggest so I don't have to send it back to vodafone!
yea, i've tried everything too, at can't get it to work! - hope someone got a solution to this!

Well I called HTC and got the name of their authorised repairer in Australia (currently on an extended holiday visiting family here), so I unrooted and returned to stock but the issues haven't changed, so I guess we can nail down that it has nothing to do with the rom itself. The repairer did hint at a motherboard issue, but as I was playing the dumb blonde at the time I didn't push it too far until I send it off. It's just painful, I've searched and searched for a fix but most people seem to be able to find a network after a reboot or by simply waiting it out. 24 hours without my Magic being able to function in it's primary use, as a phone. This is very very poor.
I have had the exact same problem, so I unrooted and all. send it in for repairs. and all Vodacom(South Africa) told me was that they replaced the main board.luckly its covered by the warrenty. hope it helps..

Thank awesome to hear its a simple fix, but not so great that it's not a totally rare incident. I'm waiting til all the fuss of Easter is over to send my poor baby off to be fixed, but in the mean time I've bought a Hero so I'll never have to go back to my Nokia E65 again. I'm wondering, as there are other Magic owners with the same problem, is this an issue with just the Magic, or all HTC devices?
hey i still have the same prob with my 32b
i will do a radio update,
will see if it's fixed then,
if not i try to unroot
This has to be almost a year old lol.

Hoping I can possibly gain some insight. The Note 3 I have had no other issues than a charging port had been broken off (wife was a little rough with it), and ended up having to replace the port itself. The port is the correct model and type for this phone, made sure of it. I factory reset the phone and I made sure to turn off the diagnostics for Samsung (since I know that can cause problems with cell phone reception). It worked for about....4 hours before it stopped finding the network. I did another factory reset and the signal came back. Am I going to have to continue to factory reset just to get service back? Or is there a workaround that I may or may not know about? The device is not rooted with the latest firmware (5.1.1 I believe), the APNs are correct, and the SIM works in other phones. I'm completely drawing a blank.
Possible loose connection inside the phone?
Possible wrong modem and CSC for your network .
But 4 hours working suggests lose connection or even faulty sim card .

I opened it up and checked the connections inside the phone itself, the wires are properly seated and tight. I'll flash a new modem with the proper CSC just to be safe.

The only way I know how to turn it off is that you have to factory reset the phone, and when you are in the initial startup (after selecting your WiFi) The very last option a Yes or No to send Diagnostic Data to Samsung. Don't know how to do it other than that method, if someone else knows, feel free to correct me here.

thanks for quick reply. yeah i have done that.
but i have issues with LTE reception. may be some other issue.
I also have the same problem!
GSM mode works, GSM/WCDMA has some failures, LTE/GSM/WCDMA has many problems! I have 1 bar or 0 bars all the time (while other phones with the same sim card have full bars).
I don't know if it is an antenna problem or really the main board problem (since software isn't an issue because I tried stock, cm based and note 5 port roms and everything has the same problem).
I'd like to troubleshoot things a little bit so I can get this repaired myself, anyone knowledgeble here so we can get our problem solved?
Last week, my phone turned off while I was using when it went had 15% battery, nothing out of the ordinary since it's a Nexus 6p. The issue were after turning it back on:
- no SIM card are recognized, I tried 2 that work in other phones
- The settings tells me no IMEI and the phone app crashes when I type *#06#
- The battery last from 2 to 3 hours because of Android OS
The phone is stock, I just did a factory reset that hasn't changed a thing.
Also, it's still under warranty but in Australia and I live in France, so I'm really asking you guys if you know a way to fix it so I don't have to send my phone at the opposite of the globe and wait months to get it back.

Sounds like one or both of your EFS partitions may be corrupted. If you have a TWRP backup of those partitions- or a mate that does, try restoring them. If not, you can try formatting the modemst1/modemst2 partitions and letting them rebuild. It also appears you have a degraded battery (not the OS), so you'll need a new battery as well. Many people are not having any luck solving #1, and if you can't solve that first, there is no sense putting a battery in the phone. If your warranty is through Google or Huawei, it should not depend on where you are currently located.
Thanks for the reply, I don't have no TWRP backup unfortunately.
Concerning the warranty, it's still under warranty but it's just that I have to send it to Australia, which is a pain.

Oh, where did you purchase it in Australia... a brick and mortar store? I think you missed the part about formatting the EFS partitions using fastboot. Yeah, it's a pain but your phone is useless as a phone now. What do you have to lose?

I had a similar issue this past weekend.
Something on my phone got corrupted and it would not recognize the SIM and if it did, bluetooth would not work.
I finally broke down and did a full wipe of everything and flashed the stock OS.
Phone is fine now.
I think my problem was related to a restore from TWRP across devices.
So, I bought this second-hand MXS just yesterday, and it had digitizer issues the previous owner claimed to have started after the Nougat update. I did some research and found it was a possible cause, among some others (not counting actual damage to the digitizer). Tried flashing a few stock firmares and, apart from not solving the digitizer issue (which I'll be replacing soon), now I don't get any signal on either SIM card slots. OS recognizes both SIM cards, their operators and so on, *#06# shows IMEI, but I don't get signal at all. I can even perform an operator search and sometimes get results (sometimes I get a "error while searching for networks" message), but I never get to register in the network. It shows "can't connect to this network right now, try again later", right now I'm using 2 SIM cards and one of them is from the only operator showing when searching works.
Right now I'm on antariksh's RRemix, my device is a dual SIM XT1572. Last flashed modem is from XT1572_CLARK_RETLA_DS_7.0_NPHS25.200-15-8_cid12_subsidy-DEFAULT_CFC.xml, and modem files show all right in my /etc/firmware folder.
Any help is hugely appreciated, even if you guys have modem files just lying around your HDDs and are willing to upload them so I can give a shot. Thanks in advance.
Did you get your issue solved?
I'm also facing same issue... if you got some fix, then kindly let me know. Thanks

Unfortunately I'll be of no help, since I sold the device a few days later to someone who bought it for replacement parts.
What I can update you in is that the device, after several modem-only flashes (via fastboot), sometimes got signal for a brief time, then went to no signal again. Since it happened the day before I sold it, I wasn't able to dig further into the issue, but I recommend you let the phone "settle" for some time to see if it starts getting signal more frequently. At least I can tell you it probably isn't a hardware issue, but I found no permanent solution. I also don't remember which modem firmware it ended up with, but I do recall that the "signal shows up sometimes" happened in more than one firmware.
