Hi to all, I'm writing here because I had my first problems with my v970 (with etotalk rom). This evening I checked my mobile and I found that none of the sim was active (I was not in airplane mode) and I could not activate them, as if they were not in their slots. Meanwhile the upper part of the device began to heat up, so I tought it could be an antenna/receiver problem. I almost forgot to say that I installed Truecaller (deleting Contapps) and updated facebook and few others apps less than one hour before the event, but I already uninstalled them to exclude some of the possible causes. I'll gladly listen to any advice. Thank's in advance. GL
Restart, and see if it continues.
Already tried a lot of times, with or without sim cards. I also noticed an abnormal use of battery.
When did the problem start? What did you do before it started? Does your cellphone always have no signal, or does it come & go (sometimes SIM works, sometimes it doesn't)? Have you checked your APN settings?

The problem started yesterday and I never experimented It till now. As I Said, before I encountered It, I updated some apps from the market and I changed the default caller manager (should I call It in this way?) with Truecaller. I also deleted my sim contacts
. I can't check apn because there are no apns to check (Android shows me the voice "mobile networks" but I can't select it
Update: I tried to restore the original rom, but the problem persists. I also made a check with the recovery, and it shows me that the device cannot detect sim cards. I begin to think that it's an hardware problem (ouch). Am I right?
What did you do in recovery that checks SIM cards? Are you talking about CWM recovery?

Nope, it's the faulty recovery that etotalk sent me with the phone. I would like to install the cwm and flash another rom, but I'll leave that as the last option
If the recovery they sent you is faulty, then what good is it? If there's a custom recovery available for your phone, you might as well go with it, not that it'll solve anything by itself.
You might try inserting some kind of shim along with the SIM card to see if the extra pressure help make contact with the leads. Careful, of course, that whatever you stick in there doesn't stay behind.

I know about the recovery, but I was trying to don't invalidate the warranty (as if I'll ever use it...). Now I'm charging the phone, it's already the third time today...
Aw, heck. If you've got warranty, just send it in.

Yep, I've got warranty, but sending it in China will cost me almost as much as buying a new one
Ok, I flashed a recovery and a custom rom, but nothing happened.The signal is still absent and the antenna heats up the same way as before. I tried to enter engineer mode and it shows me messages as "com.android.internal.telephony.CommandExcepti on: RADIO_NOT_AVAILABLE", "3G off. Cannot set", ecc... It also shows me "invalid IMEI" if I try to look at it and I cannot change it back with the AT +EGMR command (it says "Radio on" and "SIM State: ABSENT", altough the SIM card is in its slot).
I think you have to crack the case.

Hmmm... if your phone is reporting invalid IMEI numbers then I would try first to get that working as it should. Read this tutorial and re-write your IMEI numbers.
Then I would try the latest stock ROM, which is available on ZTE support website. Here is the direct link to the ROM.
If your phone still doesn't work after that, then I'm afraid you have a hardware problem.
I have had the telephone for more than one month with no problem. Trying every ROM made by Bruno with no problem at all with signal, but...
About 4 days ago, I started suffering exactly the same problems stated by ArcheoGian. I have tried everything (installing older Roms, rebooting, changing SIMs from 1 to 2, etc.) but unfortunately with no success. I just have to try to install the original ROM, but I supose it will be the same.
Afer a few reboots, I can make the telephone to search for a network, it founds it, it connects, it transfers data, I can make calls, but ramdomly (can be after 30 seconds, 30 minutes or maximum one hour) it disconnects and the red X of death (Xbox 360 times ) appears on top of the screen.
I can try to go and return from airplane mode, or search for networks that it won't re-connect.
I fear it can become a typical problem for this phone.
I am "delighted" to send it back to China and wait for two months to get it back (after explaining it to the seller and so on). Fingers crossed
@prinxo: did you buy it from eto...k? (I don't know if I can write the entire name of the seller)
Update: I tried everything it was told me (except to crack the case, at least not yet...), my last hope is to manually insert the IMEIs inside the data folder. There's just one problem: none of the methods suggested in the link posted by bcgngm works on my phone, so I need to generate the IMEIs whit my pc (I couldn't open the exe with windows 7, I'll try with win xp in a while, otherwise I have to ask someone to create it for me).

No, I bought it from another seller at Aliexpress.
As I thought: I tried to re-install an original ROM, and everything remains the same. I thought I was successfull but after one hour the phone disconnected itself from the network. After that moment, I need about 3 re-boots to get signal again and it lasts for just a few minutes.
At this point, I would disregard a software problem.
Happy happy to have to send it back to China.

Why do you say it is not working? My preferred method is to use the adb commands (and for that you have to install Android SDK). Don't forget that when you type the commands there is no output message on the screen. The phone has to be restarted so that changes take effect.

The third and the fourth ones are the only methods to restore IMEI I didn't try, just because I never used sdk and adb (and I'm not sure to be able to use them). I followed the others options (I also created the IMEI file with the russian program), but it continues to show me the "invalid IMEI" message. Can you help me, maybe showing me a good walkthrough?
This ADB Tutorial looks easy to follow. Check it out!
I got this phone a month ago and flashed various stock based ROMs with no trouble. I then tried AOSP (cm10.1, eclipse) and everything seemed to be ok although, I couldn't make phone calls because I have no service where my house is and was never able to test (I remember that in settings->about phone->system status it said it wasn't activated and it didn't display my phone number, but when I went back to stock it did display my number). Then I went back to a stock ROM and my phone would not make or receive calls. It would send and receive text and was able to received data via 4g but when trying to make a call, it would say "dialing" and then eventually just stop without making any type of connection. when calling the phone it would go straight to voice mail as if it was off. I used odin to go entirely stock and had the same problem. I ended up returning the phone and getting a new one and I am running Clean rom 5.5.1 and everything is working fine but I'd really like to try other roms but I don't want to have the same problem again. anyone know if it was just a bad phone or if I did something wrong? if so, what? any ideas would be greatly appreciated! Thanks!
You should have consulted xda before returning the phone. With your original phone, you needed to reprovision your sim to properly have your data return since you had Odin flashed. That code only works on ICS though.
The loss of data on your prior phone was from flashing CM10.1, you just needed to follow this post to resolve your issue without Odin flashing a stock rom.
Edit: The sim reprovision code suggestion is still valid BUT disregard the data loss part...
Hey folks, i tried searching here for my issue. I found many similar threads, but nothing that solves my issue.
Two days ago i started having issues sending picture messages, today i start losing network signal until it cut out alltogether.
I tried multiple sims from different carriers and got nothing. Ive tried the following:
Factory reset.
Rebooting and reinserting sim
Resetting apn settings, custom apn settings.
I have WiFi, and the symbol says "no service" nothing about emergency calls only.
The new information i have, which i didnt find on other threads here is this; i found a sim card app and tried it, its able to pull my sim card information off the card, (phone number etc.) yet i get no cell service. Any ideas?
Nexus 5
Stock lollipop
Hey @kimsgrim
Hmm so u already did a factory reset? And didn't restore anything before test?
Really stock or u changed anything (Rom or Kernel)?
But ur phone doesn't say "No Simcard found, please insert and reboot" or kind of that?
If no the simcard is fine and the phone also seeing it. The sims u tested where card which definitly work on other phones?
So two things possible in my opinion:
1) System problem: Anything is reset or not working, which should be done with a factory reset or maybe flashing another stock firmware over
2) Hardware defect of antenna. Would be sad, but no other point for be atm.
Much success
CHEERS
Sounds like the sim card reader is messed
Hi, everyone, sorry to bother you, but I'm in a bit of a pinch.
My unrooted stock Nexus 5 was running smoothly with then latest OTA update 5.0.1 until I got No SIM card error. I eliminated SIM card as problem source, removed SIM, discharged it completely and after few days turned it on and it was working. But problem returned soon and same method didn't show result. So things I already did:
- check my card in other phone: works
- check other cards in my phone: doesn't work either
- left it off without SIM for a few days
- erase cache
- upgrade to OTA 5.1.0
- factory reset
- unplug battery from motherboard for some time
- flash stock 4.4.4 from developers google com
- put some tape on card to make contact better
in this order. My next move would be to check if SIM card case pins are broken. Warranty expired month ago so there's that. Do you have any advice to give me? Is there any part of the phone that could've stayed not wiped during 4.4.4 stock flash and that's the reason problem remained?
You have a weather widget, clock, GPS location app that is causing the issue. Try uninstalling one at a time until you find the culprit. For me it was transparent weather clock widget that was causing this. Something about the way the app polls the GPS location causes problems.
I flashed stock 4.4.4 and only stock apps are present. I can either uninstall upgrades or root and delete gapps for good. What say you? I think phone somehow got "stupid" hard and I have to reset certain part that wasn't affected during flashing because it haven't once worked throughout process.
My nexus 5 is doing the exact same thing, exactly as you described, since the update. I'm losing my mind
Seeing as we both have the issue I don't think its a problem with your phone in specific. If anyone knows please help! I've tried uninstalling every app, going on safe mode, swapping sims etc

If it happened immediately or just after update try flashing stock KitKat.
Got the same trouble
The problems begun 1 week ago with interruptions with the radio, i have to restart the phone with Stockrom 5.1 self flashed and uber-kernel to get any connection. Switch the airplane mode often to get any radio signals. I ask my provider o2-germany for some trouble in their radio stations - and there was, just a few hours it worked. In a few days ago I traveled across germany, from the south to the north and back, got while traveling no good receptions, only gprs and edge. And now I switched from stock-rom 5.1 to OptiPop 5.1 the trouble begins with no-simcard ...
I will try xTraSmooth 5, when this ist not working i try an older image...
Edit:
OptiPop working now without flashing UBER Kernel. Now Issues so far!
Mine is absolutely stock on 5.1, not seen it once in 18 months and now it has done it twice in 12 hours.
I've always been completely stock and my phone started doing this every time I reboot it. Any more word on this? It also does seem my GPS looses lock on a lot too. This seems to have started since the last OTA update a few weeks back or so.
after i flash latest factory image mmb29v I got No SIM card error. There is an error in Safe Mode and SIM card not detected .pleas help me
I received an OTA Update in early to mid May. I am now forgetting which version I received at that time. ( I forget as I have done so many downgrades/upgrades/factory resets in my troubleshooting the last month!) Up until these issues, I've never rooted or flashed a ROM, or unlocked boot loader or anything. My N5 had always been completely stock.
First Issue
It all started with just the sim card. I get "no sim card" message, even though it was in there. This was my original SIM card and I had never ejected it since I bought it new. I found I could turn it off, pop it out and back in, and boot it again. Sometimes it will see the sim card again. It may take 20 times, but finally work.
I naturally got a new sim card, as well as confirmed said sim cards worked in other phones. My wifi and bluetooth were working fine at first. Working with google support, they recommended a factory reset to fix the sim card issue. Immediately after the factory reset, my bluetooth would no longer turn on nor show a MAC address. At this point, my wifi was fine.
Second Issue
In addition to the sim card slot issue, now my Bluetooth no longer works! Around this time, I received another OTA update, this time it was 5.1.1 LMY48B. I had hoped it would fix the issues, but no dice! I start reading up on the XDA forums as I am determined to start rolling back to see if this will fix anything. I unlocked the boot loaded, rooted, etc following the threads on XDA
Third Issue
I do all sorts of flashing to hammerhead-krt16m_4.4 to hammerhead-ktu84p_4.4.4 to hammerhead-lrx21o_5.0 to hammerhead-lmy48b_5.1.1 . On the final flash back to 5.1.1 my wifi now no longer works!!!!!!!!!!! It is stuck at wifi turning on and no MAC address shows. It also seems my cell data is very very slow now!
After many calls to google, I think I finally succeeded in getting a “ticket routed up”. My phone is from the play store around 10/31/2013. They keep pushing I am out of warranty. I attempt to ask for a refurb N5 without luck so far. I am not very confident anything will come from google. This being my only handset now, it is just not an option to send this to LG. My current state is my voice/txt and cell data are working. Data seems a little slow but usable. Wifi and bluetooth won't turn on. I also still have the sim car slot issue upon rebooting. After a bunch of reboots it will eventually see sim card.
What else can I try? Is there a better way to attempt to repair/reload my radio drivers? Perhaps there is corruption of sorts? I have not tried a custom ROM or radio or kernel…… I did take to a local tech. They looked at everything literally under a microscope and did not see any issues that way. I am in the USA and have a lgd820. Although we are quick to assume a hardware issue, I am wondering if there is some sort of incompatibility with the first run of N5 and lollipop….. who knows!
I’ve read all sorts of threads on the internet. It seems I am not the only one. We are very quick to assume it must be a bad motherboard, it just seems too coincidental to me!

Hi,
This link was actually what i was going to suggest. It seems you've tried pretty much everything in the book except that.
I think its worth a try. Same as any other learning process, take your time and read the whole thing once or twice until you feel comfortable with the process. Then go for it.
Darn it, I should have downloaded those programs BEFORE rooting my phone again. Now I a struggloing to get my SIM card detected again to get data to DL them! whooops!
How would I go about attempting to read my files first to see if they are accessible and potentially write down my old MACs first?
EDIT: I found this but not sure how to get that working? I have Windows 7 and CMD prompt at this point. what program is that using?

OK, I went through those steps. everything appeared to go through correctly. Still no wifi nor bluetooth
EDIT: I rebooted a second time. WHen it first boot up, wifi was on and connected to my works AP. I quickly went in and snagged a screen shot of MAC address. Oddly enough, it did not match what I had input via hex editor. Within a few moments the wifi stopped working. It is back to the turning wifi on issue..... bluetooth still not working as well.
Very interesting.....
EDIT2: I get access denied when attempting to read either files within their corresponding folders under persist.
I was able to copy my stock files into my sdcard download folder and read them there without issue. Thus seeing my default addresses for both!
Perhaps it is normal, but I am never able to edit the old or new files under persist. I basically renamed original folders to bluetoothold and wifiold. I could delete them perhaps.
Note that I put my phone into airplane mode before doing anything noted in the steps.
Any other ideas? Given that it is showing my original MAC address the one time it worked, this makes me think that it is not reading the files .macaddr at all
I have the same problem. Funny thing is, the phone is just over 2 years old and the motherboard was replaced just 9 months ago (so, brand new one).
In my case, I received and Android update 2 days before I found the phone burning hot and restarting on it's own. Then the same chain of events you describe started to unleash. Now I can't be sure if this is software related, hardware related or both.
Can't seem to find a solution to the issue either.

I'm facing the same issues and I tried all the possible steps I could find on internet trying to repair the problem.
Actually, since the latest updates I was encountering some issues with the WiFi only: not turning on either off and not showing properly the MAC addres. So I decided to factory reset, even SDcard and since yesterday I have tried all the possibile guide I found to internet to fix the MAC address not showing and the WiFi not turning on/off but nothing worked. I tried even to flash again the old factory images, such as KitKat, Lollipop, etc., to lock the bootloader again and to dismantle the phone in order to clean the motherboard, but nothing worked. Phone still gives me MAC address 02:00:00:00:00:00 alternatively with the correct one, I can't figure out on what it depends because sometime it seems to work: it shows the correct MAC, it connects to wifi network; suddenly it doesn't!
I'm really going crazy to understand what's wrong.
You'll have to dig up my final posts on this , but in a nutshell, send into LG for repair, select cheapest option they offer. Receive mint phone. My cost was $45 and about one month... I picked up a cheap $20 phone to get me by.
In other news.... I now have a 6p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
