[Q] IMEI = 0, but phone working normally?

NOOB ALERT: I am very new to this, but have done a bunch of searching and have come up empty. If I missed any threads that may have addressed this, my apologies.
Hello,
I recently tried flashing a custom rom on my e971 for the first time after 2 years of ownership and getting bored of stock rom. Rooted as described in the ROOT/BL-U/L/Install custom recovery thread for Canadian G's (zv9-zvb universal root), U/L BL with freegee and installed cwm (also through freegee). I then flashed pacman rom 4.4.4 for the e973, as it was my understanding that it would work properly. Rom flashed successfully and the phone worked for the most part (though there seemed to be some bugs with the rom).
One thing I noticed was that my imei was displaying as 0 in settings, which was a concern. After searching the forums for this problem, i found that most people with this problem couldn't connect to their operator, whereas I could connect fine (though my network speeds seemed slower than usual). No problem making calls, SMS, or using mobile data (MMS was hit and miss though).
I've since successfully restored my stock backup via cwm, tried restoring my efs partition via freegee (used freege to backup), re-flashed the JB radio for my model, but have had no luck getting my imei back (phone still works though).
The only other thing I can think of trying is the Unbrick guide using a kdz, however the kdz downloader app gives me an error when i input my model and serial. My other concern with this method would be ruining a phone that's currently working.
Can anyone recommend any solutions or offer any insight as to why this may have happened?
Thanks very much.

A couple of things... First off, to flash a KDZ, try using a flash tool 2014, it should work (worked on my F180S). Second, you could just leave your phone as is, unless you are planning to use it abroad (I am assuming you are in Canada). Unlike in other places in the world, e.g. Europe, nulled IMEI somehow works perfectly fine in Canada, which I know from my own experience with at least two different phones. Weird, but true. So, if you are only planning to use it locally, it shouldn't be much of a concern, really...

Thanks for the reply. Yes, in Canada, but unfortunately, I can no longer connect to Rogers at all. I'll take a look at the LG flash tool thread and see if I can figure it out. Still not sure where to find the kdz file though...
You mentioned you've experienced the IMEI problem. Do you happen to know if flashing the kdz will restore the IMEI (not sure if that's what you meant by "worked on my F180s"?

Take a look here: http://lg-phone-firmware.com/index.php?id_mod=20
The KDZ you need is listed under "Rogers".

I just meant that when I had to flash stock KDZ on my F180 (several times, for various reasons), Flash Tool 2014 worked perfectly for me. So, if you are having issues flashing KDZ by other methods, it's the best tool to use.
My IMEI problems were on totally different phones... I haven't encountered any IMEI issues with OG. Some people say that flashing KDZ does restore IMEI, others indicate that it doesn't. I can't say... If you used FreeGee in the past, you might have made an EFS backup. Restoring from it would be your best bet.

Thanks again. I did make a backup using freegee, but restoring through freegee doesn't seem to do anything (I get a message saying the process is complete, but still no IMEI).
I'll give the flash tool a try and report back.

Update: successfully flashed back to stock by kdz, but no change with the IMEI, and still not connecting to network. Still have the backup EFS partitions saved, but unless there's another way to restore them besides freegee, I think I'm SOL.

Update 2: After a day of showing no connection to the network, my phone decided to connect to rogers wireless today. Didn't change anything, and IMEI is still 0.

I hope you can fix it: http://forum.xda-developers.com/showpost.php?p=55471364&postcount=4

[Q] D855 Converted to D855V

my friend has a G3 D855, he brought it to tech to be rooted, the thing is it was Converted to D850 ( US Carrier Version ) then tried to mess it up, and ends up having D855V
it has no signal when i try to search netwoks, it was unable to connect
things i tried
- upgrade to lollipop using KDZ ( still no signal )
- downgrade to kitkat ( still none )
- downgrade using TOT file ( model problem, D855V cant flash tot )
- change cust.img ( still none )
dont know what to do at this point...

UP!

Up!

no service after updating LG g3 Model no: D855V
i have bought a new LG g3 unlocked version through online.
i updated my phone using LG PCsuite, but now its showing a WARNING message
"current version not available for user. can't find match cust for NT-code mcc/mnc[310410],subset[FF]"
and NO network service for the phone.

Same problem here.
Anyone?

i have same problem

Same problem. To those with same issue, haven't been able to fix? I had my phone checked in a local service center, and they say I need to have motherboard replaced. But I doubt the hardware is the problem. Anyone have ideas?

Not sure yet what is the problem. Using custom roms and various modems did not help.
No network and phone is quickly discharging and very hot.

Quick discharging of the battery/very hot I think is due to the phone constantly searching for network signal.. I removed my SIM while still looking for a fix, and this helped with the battery.
I can still connect to WiFi but other than that, it's not really a phone if can't do calls/sms..

Mate! Did you find a solution to this problem? I got my phone off ebay.in and after the lollipop upgrade the same thing happened. If you got a solution can you help me out as well?

same here my D855 was changed to D855V by octoplus now need a way back, also here no signal.

Worth a try?
Have the same problem. Asked around in the market from the tech guys. According to their understanding and experience we should try flashing it with a d850 rom as they believe the phone is actually a d850 model. Would have done it but i don't know how to unbrick incase anything goes wrong. so anyone willing to try and if does let me know about the results

Well i just bought the phone last week. For me there is a lot to loose. Right now i'm just not getting signals. Rest of the phone is working perfectly wifi,cam, music etc. =p

Flashing with d850 will kill it, I tried and now dead, it was a d855 and became d855v after octoplus.

Can you please elaborate what you did and what was the result?

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

no network

i bricked my lg g3 d855 during flashing completely dead no download mod Now i unbricked it with "boarddiag" and same D855 but no network and a lot of bloatwares . i tried KDZ & TOT but no signal fix... now what to do for network

waiting for solution..there are a lot of people with that problem. I dont know why this happened ... when i clean flash to stock 30b kdz problem solved for few days and then... still persist

The most annoying LG G3 problem with LTE signal - [SOLVED]

OK guys, i think that I found the solution that will be PERMANENT fix of the problem with the LTE network on our G3 [ I own D855 but i think that this will be equal to all other models ]
So.... i spent hours ... many hours to find this so i hope that you will appreciate my work and maybe buy me a coffee if this help to you too.
1. I had problem, when my phone connects to LTE network and WiFi at the same time my network coverage disappeared.
2. After few days my network coverage started to disappeare with no logic... every few minutes - i have network and in a minute i dont have network and that was a proccess that never stopped.
What i tried :
1. I tried 30b kdz
2. I tried 30b via TWRP
3. I tried all different modems that i found with all this rom variations
4. I tried to go back to stock lollipop kdz
5. I may be tried something more but i wont to think more for that annoying problem any more so... that is enought
So here is what i found:
1. Simply use a Prop Build editor [ i used ES File Explorer to edit Build.prop ] to go into the build.prop and change the "telephony.lteOnCdmaDevice” value from 0 to 1. There are two lines on in the G3 build prop. Make sure both have the value of 1. Then save. Then reboot.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
2. Deleting the file LTEconfig.apk works sometimes. The file is located in the folder: / System /app
Just copy it to other location and delete the file and restart your phone. I said sometime because with some combination of roms and kernels and radios it helped me, but not in every variation. You have to try yourself.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your LTEconfig.apk file !!!!
3. Next thing that i found is that editing the build.prop with this values have a massive effect too :
ro.telephony.default_network=11 or 13.
ro.ril.def.preferred.network=11 or 13.
ro.build.target_country=AU or COM or to your country code.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
4. Try to Disable Fast Dormancy. You can do this by simply open the hidden menu in your G3. This can be done by simply dial *#546368#*855# on 6.0 D855 or 3845#*855# on 5.0 D855 [you will have to find the codes for the other variations of G3]
so hidden menu > Modem Protocol > PDP Setting > Set LG Fast Dormancy > disable
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
So... i have no problems anymore with this network issues
If someone find something that can be done more permanent than this, i will be glad to hear and understand but for now this is OK i am sure because we can use our phones as phones.

some people (including me ) have data icon missing in stock kdz and lose sim options too after rooting :/ are they any solutions for us ? I searched for 5 days :/

http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/ try to download stock kdz or tot .... some older version like 10a for example. Flash it with flashtool 2014 or lgup but first in twrp advanced wipe and wipe everything... then when you start your phone "from beggining" try to OTA update to lollipop.... i hope that this will normalize your problem. I am not sure... you have to try it. You should restore backup from when you were stock ot efs partitions just in case before flashing new kdz...
Write if it helped because there are many people out there having strange problems with network connection.

Ok, its not lost time in fact... this means that you dont have hardware problem its software related and mostly in 30b version that you have installed.
In fact my last rom flash was with file downloaded from here http://devtester.ro/projects/lg-firmwares/ as thurasisyein said.
I dont know why.. for no reason... i just coughn`t find 30b 16gb kdz with fast speed of download here in the forum and i tried.

Thanks for this thread!
I had no 4g/lte connection after i flashed MM KDZ, and no matter what rom i installed it didn't work, after i tried these fixes i found an old backup to restore, after that straight to 4g.
Now installed another rom via twrp and 4g sticks. For me i think it was a regional issue. (on 855) Denmark.

OK, try to insert your sim card into another android device. Remove your sim card while your G3 is into airplane mode... insert it into another android device and wait to connect to 4g... when this happened put it back to your G3 and airplane mode off and see if this will make things better.

Hey guys, I have an AT&T branded LG G3, unlocked, under a mexican network provider (TELCEL), every band is supported by the phone and I'm using their SIM. I'm currently using Fulmics 4.2 Rom, but even on stock rom, since I received the unit, whenever the LTE signal was too low, or I made a call, the phone would drop the signal and switch to 2G. The problem is, once this happens, the phone remains on 2G and won't change automatically to LTE. I have to turn it off and on for it to recover the LTE signal. Will this fix the issue? Or do you think I have a faulty unit? Thanks!

4g icon missing
Please Help My LG d855 On Stock 6.0 4g icon missing but data is still working fine , but in another rom like AOSP , 4g icon is appear and fine , Just in Stock Rom my 4g icon is missing , But Data is fine , Just a icon , Anyone Help , Thanks

This is what I was looking for all month, thanks OP. I use a h2o sim for mt vs985 and every time I booted up my phone would complain about a non-verizon SIM. Also, I would only get 3G.
Changing the target carrier to ATT and default band to 4 in these settings resolved this after a reboot. The error is gone and I now have 4G. Thanks for telling me about this!

@mccloud90, thanks for this thread. My problem is slightly different (it it can be called "problem" at all).
Using an app called LTE Discovery, I can see that modem always chooses LTE Band 3, which is more power-hungry than other ones. For example, in my country, LTE (4G) Band 20 is much more power-efficient, but, for any reason, modem never chooses it. I can force the selection of Band 20 thru the hidden menu, but this comes with other annoyances, like the fact that I cannot do or receive telephone calls. In the other hand, using Band 20, I feel much less power consumption.
So the question is: are there any way or workaound to tell the modem/sytem TO PREFER one LTE Band?. Maybe some build.prop configuration or a .sh script?
Thanks and, yes, I know this is not an easy question =). I just wanted to know your opinion.

After installing Marshmallow using the KDZ firmware, LTE was not working with a Cricket SIM card accessing the AT&T Network. I then made a phone call and received an automated text from Cricket to provision my phone and this fixed the LTE data connection. The SIM card method posted by Varna above may also work to generate a provisioning request from the carrier which could resolve some connection issues.

Reflash stock on same base as the backed up rom..flash twrp and restore the twrp backup

Hi guys, did anybody solved that? Have similar problem , just don't have backup.. Net is full of same issuse but no solution.

There are lots of threads regarding this problem. Main Issue are chinese refurbished phones with cross model boards, and overwrited IMEIs to look like other models: D850 -> D855, etc.
You can check if its your case unscrewing the back plastic and checking the model on your Motherboard, thats your actual phone model. After that I recommend following this steps:

Help save a bricked lg g3

:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!

Folks.
Got the same problem now (with my wife's phone). I'd appreciate it if instead of helping people privately you'd tell everyone what to do to fix the problem.

I had the same problem, downloaded .tot file via IMEI check (can't remember where from) and used that .tot file with BoardDiag, flashed everything as in tutorial (google it), it was 4.4.2 Android, couldn't update it (software is up to date) so I rooted it, flashed twrp 3.0.0 and installed Fulmics 8.0, it works now just fine
