Hi
Ok so my phone was working fine on a custom ROM when suddenly yesterday an exclamation appeared next to the phone signal and stopped from receiving/making calls and texts. I thought it had just crashed but after soft and hard resets and changing to a few others sims I just can't get my phone signal back.
Really strange as everything was working fine. I now have trouble flashing custom ROMs and am struggling to run a stock ROM because I'm on a mac.
It's driving me crazy as my phone is now useless.
Any ideas guys?
thanks
Quick update
I've managed to get the Leo Lite ROM running and everything is good except that damn exclamation mark next to the phone to phone, which means I can't get the phone working.
Anyone know know why this is???
Have you tried the sim in a different phone?
could just be a simple issue
And I know it a simple thing............but have you got flight mode on?

Thanks for the reply John.
Yeah currently having to use the sim in an ancient motorola and it works fine, tested with calls and texts. Also tried turning on and off flight mode but still that bloody exclamation mark stays.
That sounds like its been blocked. Theres a network there it just isn't letting it connect. Did you buy it second hand? or off ebay?

Hey Sam
Do you know what, I did buy it second hand, from a reputable store in town.
However this raises more questions than answers;
1. Why would it be blocked after several weeks of normal use.
2. Doesn't some sort of message need to be displayed stating the handset has been blocked.
Does anyone know if this is what happens when a HTC HD2 is blocked? i.e. the exclamation being shown all the time.
I presume a handset is blocked for security measures like theft. I will take it back to the shop tomorrow, they will have all the details of the person who sold it to them.
However is there no way this can happen from flashing custom ROMs? Even though that doesn't really make sense cause I had a ROM that was working fine and this happened when I was out and about.
It could be a bad rom, but it certainly wouldn't be in every rom.
I think id try going back to the stock rom, radio and spl (i.e an sd card flash, do you now if it has a provider locked rom?) and see if it is still there. If it still won't work, then it's definately either hardware or network.
The reason it could have taken weeks is, , seller trades in phone for cash, waits a little while, thinks 'i know'..., reports the phone lost/stolen to claim on insurance, insurance won't pay out without the imei being blocked.

Well I've tried flashing at least 6 custom ROMs, all show the exclamation mark.
The phone was sold to me as being unlocked to all networks, however I never tried with anything other than a o2 sim.
Now going back to the original ROM has its own problems. First off i'm quite new at this so sorry for sounding silly. How on earth do i go about finding out what the original stock rom, radio and spl is?
When I have these I can't easily go back as I don't have a pc, using a mac. I would have to use the sd card way but I can't find an official signed .nbh file.
I have a brand new T-Mo US HD2 with similar issue (out of the box). It's like the radio will not initialize. Did hard resets, tried to force it finding a carrier, etc, and it just will not turn on the radio.
I did find out that there is a likely issue with my SIM slot. If I attempt to remove my SIM card (which works fine in other phones) it is almost unremoveable and feels jammed in. However, once removed, I get connectivity via wifi and touch response is great.
If I insert a SIM card, it takes a LOT of pressure to reinsert it (yes, inserting it in the correct orientation), and the phone cannot connect turn on the phone's radio. Also, I get random phone.exe and credential.exe error message (plus the phone becomes very slow.
Don't know if you have any of these other symptoms, but the lack of connectivity sounds similar.
Supposed to get a replacement HD2 today, and we'll see.
I had the same problem too. I got unlocked code from tmoile and everything working fine for a month. It was working great after upgrade the latest rom 3.14 from tmobile download site (i got the message from them to upgrade), until i went out off country last month then the phone could not turn the phone's radio on. It kept at airplane mode. I been try to flash back and forth all the tmobile .50 stock rom and still having the problem.
Does any one know the issue to fix it? TIA
Looks like a hardware fault. You need to open case and check bottom two brass hinges are in working order and correctly hinged to make contact with antenna which is on the rear case at the bottom.
Follow the guide of opening s HD2 on YouTube there is a factory guide to dismantling the HD2.

Thanks for reply xlr8me. I just check the two brass hinges at the right side of usb connector. It looks fine to me. The other thing i didn't mention on the above post I was flash the dft_leo_nand android after tried all the stock rom from tmobile and the android said "no sim card", i also checked and cleaned the sim slot. Do you think any thing else to cause that problem?
One more thing without the sim or sd card the about phone show up all info of phone: imei, serial..... But with sim card in it just blank when i read the about phone hardware info. Thanks again
Did you try simcard from another carrier?

Yes I did tried the sim from the carrier of the asia country i was traveling to last month, that why i call tmobile to get the unlock code before i go. When i was there and inserted their carrier's sim and it won't work, even when i get back to U.S. I been tried either tmobile or at&t sim too. The phone radio won't turn on. The rest is working ok except those above error messages "A problem has occurred with device.exe" and "Credential.exe".
Do you think i can reflash with WWE rom .50 radio instead of tmobile's official rom?
Thanks
htcphonelover,
You will have to reset the phone back to default rom from htc website. You may also need to reformat sd card but the radio should still work regardless of whether the sd card is in or out.
My only concluding thoughts are that if the above fails to work then try a different sim card and still no good then probably something with the motherboard on HD2.
Good luck and update us with any new info..
Hi all,
A few days ago I turned my Galaxy S II on to find the no signal line notification in the top right corner. Upon going to search for 'Mobile Networks' the phone is telling me to 'Insert SIM card to access network services' - I have tried my old and a new SIM card, both have given the same response.
I've tried factory and hard resets. Strangely, after the hard reset, my music (assumingly in USB stroage) is still there..?!
Even stranger is the phone's inability to show the IMEI - my provider has informed me that it hasn't been blocked, something I suppose.
The phone cannot connect to Kies however is recognised by my PC.
Any help/suggestions would be great, otherwise I may have to send it for repairs...
Thanks,
Guys I have a strange problem here...even though I am not charging my mobile it still shows charging symbol in the status bar. ...I restarted my mobile and I even flashed a different rom... nothing has worked...please guys help me out...

Restore your EFS backup. No backup ? A couple of options; search for threads on here about recovering IMEI and or/EFS. Lots of them with various things you can try in order to possibly fix the problem. If they don't work, you have two options.
One, service centre/authorised repairer. If you're lucky, they either won't notice or care you've been messing with the phone & they might fix it under warranty. Two, contact a member on here called Odia by PM and wait for him patiently to respond. If you hound him, he'll probably ignore you (quite reasonably too). He can sometimes recover IMEI/EFS for a small 'donation' which will probably be much cheaper than paying Samsung to fix it.
Edit - READ THIS FIRST: If you've never messed with the phone (rooted it or flashed non-stock firmware), then send it to Samsung in the first instance before you try and fix this yourself. If you haven't been mucking around with the phone, you shouldn't have any problem with warranty service. If you have, try the other suggestions.

I have just received a Nexus 4 off ebay today. Said it was a month old, unlocked etc.
I got it for the Mrs. She powered it up, and inserted her O2 sim and it said "no service".
We haven't done a thing to the phone but turn it on. Is there a reason for this?
I've attached the software details.

Have you tried to set the Settings->Wireless&Networks->Mobile Networks->Network operators on "Choose automatically"?
It may have been set to another carrier by the previous owner.
Clicking set automatically doesn't seem to do anything. And when she clicks mobile networks, which usually shows a list, nothing happens.

It does come up with a IMEI when I go into settings. As you can see from the attached, there is no signal at all. I've tried mine and her sim. This phone looks brand new, the guy said he used it for a month, it's running 4.3. Everything works but this.

Did you update the APN or are you just going to keep telling us that the guy used it for a month and that it looks brand new?
Whats the point of even putting in an APN when I have NO signal and it can't even scan for networks.
Secondly, I think it's faulty. I noticed the sim tray isn't sitting flush, with or without a sim card inside. And more worryingly, I just tried the to add an APN, it didn't even save, and there is this rippling effect on the screen if I press the back of the phone, or front. It's in the exact same spot. Even holding the phone in the hand and gripping causes the effect, It's like an invisible stick is poking at the screen, distorting it. Hard to explain.
Maybe all this is irrelevant, but I'm suspicious.
Have you tried performing a hard reset? It could possibly be blacklisted, amongst other things.

Looks like the IMEI is blocked. This can mean the phone is reported stolen and therefore the IMEI is blocked.

Thanks for that. Both tests included a seperate paid one, show no problems, no blocked IMEI.
The only road I can think of to go down now is the whole unlocking bootloader, flashing other modems/roms etc.

is that micro sim working in another phone? if your sim card works in anotger phone, then the n4 itself is the issue. my first n4 i returned within a day, it wasnt reading any sim cards at all.
Both sims work fine in other phones. I'm so annoyed by this, it's near mint condition. This guy had to know it was faulty surly.

it could be the phone itself then. the n4 has a known issue with faulty sim readers. btw, was your sim cut down to a micro size or is it an actual micro sim?
btw, this simms works fine too
It's a proper micro sim. I just want to be sure that it's nothing my end before I start moaning and getting refunds. But at the moment I think there is no other option. Would trying to flash another radio make a difference? Or is it futile?

the radios might play a role for a little better or worse reception, but one wont not give you a connection and another will is highly improbable.
It's imei related. Since you stated it's present & not erased, that means it can't register with the network due to a possible blacklist.
Also micro Sims and normal Sims that are cut will both function in the nexus(I've tried both).

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.

Hi all!
I've bought a Nexus 6P in september 2016, worked fine in every part until yesterday: my phone stopped showing signal strenght and says "No service" in the upper left corner of the screen.
I was on a custom ROM (Pure Nexus) but:
- Restoring factory images didn't help
- Restoring the oldest Marshmallow factory image didn't help either
- Erasing cache didn't help
- Switching to 2G and 4G didn't help
- I did a network settings reset, nothing changed
- I've switched to a new SIM card, nothing happened (old SIM card worked well on other phones, like this new one)
- I've never touched EFS partition but my IMEI is still there, so i don't think it's a network problem
So... Any ideas?
Oh man... I was hoping it was just me. This has happened to me too within the past few days, twice.
After waiting a few minutes it came back. It *May* be they are doing tower work. That's what I'm hoping.
I am on Verizon Wireless on the 3.79 radio if that helps add info to the pile. What radio are you on?

I'm on the same radio, latest radio in latest 7.1.1 release, january security patch, as i said before, installing the oldest Marshmallow release (so the first radio released by Google) didn't change anything!
My provider is Vodafone IT, I don't think they are doing some tower work, because everything works fine on other phones and the same SIM card in!
Good day,
Got same issue few days ago, after phone restarted due to installing January security patch. Phone was not rooted on stock firmware 7.1.1 with locked bootloader.
Cellular network don't work at all, if try to find network manually it return: Error while searching network.
In *#*#4636#*#* all switches in OFF position and cannot switch on. IMEI available.
Also when try to make a call(without network of course) it return: Turn off airplane mode to make a call. Of course it not turned on.
I try flash vendor, bootloader, baseband/radio(3.72, 3.78) previous stock firmware 6.0 and 7.0.
When flash cyanogenmod 14.1, SIM card was not detected.
Carrier Elisa (Estonia), bought in November.
Any ideas?
If you're not on Verizon, I would just switch back to 3.78 radio. Flash it manually. Don't see how that wont fix your issue

Hi mate, a friend of mine have a Nexus 6P, we are on the same carrier and the same 3.79 radio, everything works fine on his phone!
So my problem is not radio realated!
Radio 3.79 is also good for other carriers over Verizon.

Hardware problem with Huawei. The gold contacts on your SIM card are not making contact as they should. Likely a problem with the SIM tray.
Eject SIM card and put some scotch (cello) tape over the card to hold it in the plastic tray. You may need two strips (I did.) Now reinsert the SIM tray. All should be well now with your cellular connection.
Added thickness of the tape holds the SIM contacts to the connectors inside the phone tighter when the tray is closed and the problem is solved.
I did this about three months ago when I started having this problem and have been fine since.

Hardware problem with Huawei. The gold contacts on your SIM card are not making contact as they should. Likely a problem with the SIM tray.

Read this productforums.google.com/forum/#!topic/nexus/LLt6mlP_nto looks like hardware trouble. I cannot use warranty service at present, I'm at sea for 2 month

Yeah, me too, I've bought my Nexus 6P trough eBay and was a private seller, it seems that private sellers are not required to provide a warranty...

If you buy from EBay your only warranty option is Square Trade but if your phone was bad when you got it you can file a buyer protection claim
UP!
Noone else had this problem?

It seemed like other people did report having the same problem and their solutions, if they had any. Maybe you should contact your carrier. They might see a problem on their end.

I know you tried an old SIM, but have you been up to Vodafone to get a new replacement SIM as the next step? In my experience they are happy to replace at no charge. If Vodafone IT's new SIM doesn't work, just try a 3 ITA or TIM.
had this issue ONCE, and flashing the proper vendor file again fixed it.
no idea how or why

Thanks but I've already re-flashed factory image, so vendor is built in the restore procedure!
So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?
locked and unlocked bootloader,
hard factory reset,
flash google factory image and erase all internal storage,
wiped dalvic/cache,
flash vendor image,
flash different radio and bootloaders,
but still no service and no data. i think it's hardware issue and i have no warranty
