Radio off / no network - LG-H990DS - do I have any options? - LG V20 Questions & Answers

Hello,
Hoping someone may be able to help me
So this morning I lost the ability to make voice calls and use mobile data on my LG V20 (H990DS variant - totally stock). In the top right-hand corner where it shows the mobile network strength I have an empty box with an X in the top corner. Everything else on the phone is working hunky dory. Strange as the phone is stock and this didn't happen after an update, etc. Obviously it could be a hardware failure but I'd like to rule out it being a software problem as I really quite like the phone!
The phone knows a SIM card is installed as it knows the IMEI, APN settings etc. However it just won't connect to a network. I've checked the settings and the service state is set to "radio off" and the mobile network state is "disconnected" which makes sense given I can't get onto a mobile network.
Question is how do I turn the radio back on? I've tried what I think is the obvious stuff:
1) Removed the battery, left off for a couple of mins and rebooted (hoping it will then rescan and find the network) - no change
2) Factory reset - no change
Given I have the H990DS variant do I have an options? I say that as I thought this variant wasn't particular friendly in terms of flashing, ROMS, etc.
I'm a n00b but can follow instructions so if anyone has ANY advice I'd appreciate it!
Thanks muchly in advance.

Sounds like a hardware failure
Sent from my LG-H910 using XDA Labs

It could indeed be a hardware failure but I find it odd that it can read the SIM (knows the IMEI, APN settings, the number, etc) and I seem to recall when I first got the phone I had to jump through some hurdles to get the SIM to work.
Is there no way to toggle the radio on/off? I've tried *#*#4636 ... but it won't give me access to the phone information section to reset the radio here ...

did you find a fix?

HELP! Unable to connect to any mobile network - DHD

Hi Guys,
Wondering if anyone could help? I think I may have turned my DHD into an expensive mp3 player! I don’t seem able to connect to any mobile network Apart from that the DHD functions perfectly (working wifi/gps) - it has been working fine in the past
I can’t make/receive any calls / text message. When I try to connect to a mobile network I receive the following error:
- If I choose the network manually myself (o2 for me) I get "Your sim card does not allow a connection to this network"
- If I try going for the automatic option I get "Unable to connect to this network at this time. Please try again later."
- I'm also getting the notification every 10 minutes to "Set current time" - I don't know if this is related but I assume so since both issues started at the same time!
The problem occurred when I decide to give RCMix a go through ROM Manager. It appeared to flash fine and was running smooth and quick until I noticed a few hours later I had no mobile connection I'd done this a few times before with RC 7 and CoreDroid and hadn’t experienced an issue before.
First thing I tried was to recover to my previous setup before the flash (using ROM Manager) - the phone restored however the mobile network still remained unresponsive! ...this was the same for all my previous backups. I tried clearing cache and dalvik-cache. I even tried reformatting the phone at one point.
I know it's a fault with the phone and not the sim, I'm just not sure what. I've tried my sim card in another DHD and it worked fine. I have also tried different o2 sim, an orange, vodaphone and T-mobile sim card in my phone – all of which give the same problem.
I’ve tried resorting the phone with a few different RUU’s, and even a German one just because it was o2 branded and I’m on contract with them:
- RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26.03.02.26_M_release_155891_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed

- RUU_Ace_O2_DE_1.32.207.1_Radio_12.28a.60.140e_26.03.02.08_M_release_153755_signed
I then re-rooted the phone with the use of Visionary+.
I’ve tried turning the radio off then back on, both by switching airplane mode and by using the hidden option *#*#4636#*#* and I’ve also tried re-flashing the radio and even a different more up-to-date radio:
- Radio_12.28b.60.140e_26.03.02.26_M (original)
- Radio_12.39.60.19_26.06.04.06_M
I’ve checked out the APN and it appears to be correct for o2.
I’ve done simpler things like restarting / powering off, removing the battery, re-seating the sim, re-seating the sdcard and booting without the sdcard!
All in all I’m running low on idea’s Could anyone please help or throw some idea’s at me, it would be very much appreciated!
Thank you.

Did you try on your phone pad to type *#06# in order to check your IMEI?Do it and check on your phone's box that they are the same
Sent from my Desire HD using Tapatalk
Double check your SIM card slot to see if its clear of any debris. Other than that, there is a definite fault. Was your handset originally branded?
Sounds like a blacklisted imei.

HTC HD2 with error connecting to the network problem
I have the same problem! I bought a phone from ebay "new" and I have not been able to connect to my network AT&T. The phone has android gingerbread 2.3.2 Nand, and I have tried everything in the book to see if I can connect to the network but to no avail. I have been going on forums for the last three days, and if anything, I just want to know what is wrong with the phone. My sim works on other phones fine. There is enough signal in the area (ive always had signal where I live), and tried resetting, taking the battery off, flashing different roms, even went back to Winmo and nothing has worked yet. My IMEI on the phone was different from the one the box, but was the same on the phone as on the inside IMEI.
WHat the heck is going on? Please ideas or help!

Thanks for the quick replies...

Tried clearing the slot, there is no visible signs of blockage... also I bought the handset second hand - I've never seen any branding however when I bought it the previous owner did tell me it was previously locked to vodaphone and he had rooted it so that he could use other sims cards. Which is why I orginally tried a vodaphone sim card too.
Thanks for your suggestions so far guys
Just a quick update, I've been grasping at straws and I've also tried a few more bits below, none of which have worked... I think I may have to leave this one to rest. Just wanted to let others know who may be experiencing the same issues

Replacing the mtd0.img as mentioned here: http://forum.xda-developers.com/showthread.php?t=691639
It sounds like a fault. If it was network barred you would still receive a signal, for emergency calls. Can you return the handset to HTC for a warranty repair?

I still get a message on the lock screen saying Emergency Calls only - although admittedly I haven't tried calling the emergency services to check if it gets through.
Not being the original in-store purchaser I don't even know the age of the phone but I'm guessing probably over the 12 month warranty period, sod's law - I'll give them a ring and see what they say

My DHD was from the first batch and is still covered by warranty. How did you check to see if the IMEI was blocked?
I had a similar problem to this one. My mobile data connection gave out after my DHD's temp reached about 38 degrees while playing with it in the sun. A little while later I lost coverage completely, same as you. I tried everything, flashing ruus and re-rooting, re-s-offing, everything. Ten different ROMs, radios, kernels etc.
Eventually I gave up, figuring I had confirmed it was a hardware issue, and popped my sim in my old nokia so I had a usable phone and to get on with my life after wasting so many hours. I left the DHD with the battery removed, and ended up not coming home for a couple of days.
When I got home and decided to start playing around with the DHD again to see if I could get it working properly, I noticed the issues were gone.. I've tried to reproduce this problem out of curiosity, leaving the led light on high for a while, making the phone hot. Nothing. Since then I've flashed everything imaginable, and I've switched back and forth between two radios all week. No problems.
Strange, I'm guessing I have some form of hardware damage, but everything is running smoothly now at 1,5 GHz - no unstability of any kind.
I have done that actually! I took the battery off, and put the phone back in the box just to get on with my life. I left it sitting for a day and a half I guess, and I came back BUT unfortunately, unlike you, the problem is still there. The phone tries to look for signal, but it can't connect to the network. It does find the network and identifies it by name, but does NOT connect to it.
Sounds like a hardware fault Bob - Give it back to Rob!
or try and get HTC to fix if still in warranty?
Thanks! I thought so, too!
Hey did you solve problem?
I have had that emergency calls for 2 day,s i am waiting only. Please help.
If you find that your GPRS data connection connects but you have no GSM signal do the following
*#*#4636#*#* choose radio off and then radio on, be sure to be in a location with a STRONG GSM Signal and your phone should connect. I have had the same issue with my Desire HD and have been surviving with this workaround as nobody else seemed to know
Stiill same :S Selected networkd unavailable error
Try changing sim, or it sounds like blacklisted IMEI.
But my sim works on other phones and other sim cards work on my Huawei?
I was reading through this hoping desperately that somebody had found a solution. I had switched to Cyanogenmod recently but had GPS issues, so I tried flashing a new radio and RIL. Now I can't make any calls/texts, etc. as described here.
Tried several other radios/RILs, tried nandroid restore, tried flashing whole new ROM (LeeDroid). Still the same issue. Tried the *# codes listed here, no luck.
Please let me know if anybody has solved this one. I really don't need a paperweight right now...

Nexus 4 No service

Hi, My Nexus 4 got no service already 1 week++. I already tested with the other SIM card and I also do a research on Internet. On Internet, also got many people faced this problem. On Internet, many people said the nexus 4 cant accept the SIM card that is normal SIM card cut into micro SIM card, must use the original micro SIM card. I also try with the solution and I bought a SIM card that is original SIM card but the micro SIM card also doesn't work. All the SIM card are cant detected by he nexus 4, will the Sim Card tray broken. My phone are protected by cover since day one and never dropped into water. I wish LG can fix this problem and help me to fix this problem, this really cause me a lot of problem. Regards, Tang.

check in settings if you have a baseband installed sometimes it uninstalls by itself so that could be the problem

Settings > About phone > Baseband version
Does the phone ask you to insert SIM, or are you unable to connect to your cell provider?
If you are asked to insert SIM, you may have a bad SIM slot (broken pin contacts), or the SIM is placed incorrectly in the slot.
If you just have no service, check your phone number is displayed correctly in "About phone" and try to scan for available networks in:
Settings > Wireless & networks (more) > Mobile networks > Network operators
then use "Choose automatically"
Will the sim tray broken. My nexus 4 is running JB Stock and no root.

Had the exact same problem. Had no service at all (the network icon was just a triangle), no baseband, no IMEI. This is what I tried so far. My phone was stock 4.3 before my experiments :
1. Tried toggling *#*#4636#*#*, tried all the options there - no luck. Radio was "off", and no matter how many times I tried to click on Turn On Radio, it wouldnt start
2. Tried switching Sim cards, from same operator and from a different operator, no luck
3. Did a factory reset using the settings menu - no change
4. Finally, rooted the phone using http://forum.xda-developers.com/showthread.php?t=2010312 (First time ever, complete noob here). Everything went smoothly. Installed all the standard stuff from the 4.3 image.
Now, I could see the radio intermittently turn on and off - what a relief ! Atleast I knew there exists a chance this is not a hardware issue. I was getting service for 10 seconds, then it was going off for 10 seconds. This was happening continuously.
5. Tried *#*#4636#*#* and toggling all options again, (even GSM only, WDCMA only, preferred etc). I am in India and using Idea Cellular.
6. Searched like crazy on the xda forum for possible solutions - decided I'll try out a different radio version (I had 0.84 on mine) from here : http://forum.xda-developers.com/showthread.php?t=2087227 - If you're a complete noob like me and dont know what the hell I'm talking about, trust me, flashing a radio is not that difficult. Just refer to my earlier thread link
7. Tried flashing each and every radio from 0.24 - 0.84. Mixed results. Except for 0.83 and 0.84 all other radios atleast maintain signal throughout. However it never turns "blue" - I cannot access the internet from my phone - I have a data plan, the apn information is correct and every other setting is proper (airplane mode off, data on etc). The other odd thing is I can call and receive calls, however there is absolutely no audio !
By elimination - I think there are only two options here - either this has something to do with the 4.3 update altogether, or this is a hardware glitch on the nexus 4 which is activated by some unique sequence of steps. Please note I did NOTHING "illegal" on the phone before this problem - no rooting no custom software, not even any apps which mainstream users would call "shady" - just the usual FB, Mail apps, my corporate mail account.
Any ideas here - I am going to go ahead and try flashing my phone back to stock 4.2.2 again, and hope that works !! Please help ! And apologies for the tremendously long post first up

NoobNexus

i recently buy a nexus 4 from ebay, only for nostalgia, so, when i receive the cellphone, i turn on without a sim inside, connected to wifi and the phone request for 3 upgrades of security, the nexus was in 5.1.1, the last than ir support, so i accepted the upgrades and the nighmare start, when i put my sim, the nexus not recognized it, i try everything, put in airplane mode and back and nothing, full reset from recovery twice and nothing.
So, i unlock the bootloader, install a recovery (clockwork) and root, after download from google the formware 4.4.4 for nexus 4, start the downgrade, when my nexus wake up in kitkat with my at&t (mexico) sim inside, the same problem, still not detecting simcard, i connect to wifi and the cellphone request for an upgrade, android 5.0.1 , click in next and the nexus start downloading and installing the upgrade, after 15 minutes, again with the sim indide, wake up with lollipop and the signal come back again ¡¡¡¡¡¡¡
My nexus after 24hrs is still with signal, whitout problems, but still request for the other 3 upgrades ( android 5.1.1 and other two upgrades for security), but with previous experience.... i will keep in 5.0.1......

[Q] Unlocked G2 on emergency calls mode only.

Hi all,
This is my case with the hope of getting any help or lead in order to solve my problem:
After a long research I bought an brand new LG D800 already sim unlocked in the US and brought it to my country (Costa Rica). I made sure the frequencies supported by the D800 are the ones used in my country. In fact 2 years ago I bought another phone that uses same frequencies and had had no problems ever.
As soon as getting in my country I placed the SIM card I'm using in my current phone into the G2 and it recognized the signal and connected to the operators network. I started to make and receive calls almost immediately, and also SMS' without issues. So I started to migrate all my data from the current phone into the G2. I used Titanium Backup for this, so I rooted first the phone using the guide I found here, and basically what I did is installed the apps from Google Play and then restored data using Titanium.
After the second day of use suddenly I found out that I wasn't able to make or receive calls since the phone lost connection to the operators network only allowing emergency calls but the signal bars were full (see scren capture). Sometimes when restarting the phone I get "Phone not allowed MM6" message just after the phone tries to connect to the operators network.
Went to the phone company offices and they tried to help me and made some simple tests, without changing anything inside, such as checking Android's network configurations, checking in their system to verify the IMEI wasn't blocked or reported (the IMEI is clean), also checked the sim configuration and after more than 45 minutes they were not able to find anything wrong in their system or with the phone itself. They also made a final test taking a working sim and put it into the G2 and gatting same emergency calls mode, and took my sim from the G2 and put it in another phone and that phone was able to make and receive calls. So they concluded that the phone has a "built-in" configuration or damage that impedes the phone to connect to the network. They finally suggested to ask the seller to apply the waranty, which is not a viable option since I'm not in the US anymore. This G2 is using the stock ROM (see screen captured).
I've been in close contact with the seller, and he had shown interest in this case but unfortunately hasn't been able to provide much support or help to solve the issue. He reports that he has contacted other buyers of this same phone, also sim unlocked by him, and they all are using their G2s normally. Didn't provide where their locations are tough.
My own conclusions here are that the G2 IMEI is not blocked by the phone company, that there is some kind of fault in the phone that when trying to connect to the network, the network doesn't "like" and rejects connection, althought it worked at the begining, and I'm not able to determine if the fault is software or it's in the hardware of the phone.
So I'm trying to understand what my options are at this moment:
Try to return the phone to the seller, or ask an LG representative in my country to change the unit. Which seems to be very difficult.
Reflash the unit with a stock ROM and reestablish the warranty. But being unsure if this will solve the issue.
Reflash the unit with a new ROM and loose the warranty, and again, being unsure the issue will be solved.
I'm really frustrated and at this moment and have no idea on what to do.
Any ideas or insight will be appreciated.
Thanks.
NOTE: I reinitialized the unit and lost any signal (see screenshots) but received update notifications from Google Play and was able to upload the screenshots into my Dropbox although no signal is shown in the status bar and no WiFi connection is established, only data connection thru APN (I Assume).
Go into status, what's IMEI say?
Sounds like EFS issues. I take it you didn't back it up after setting up on carrier and flashing?
Of so, you have some manual work to do with diag mode and a couple apps via pc.
Hi Steamer;
Under status I see 3 items:
1) Phone Number: shows"Unknown".
2) IMEI: shows the number printed on the box, on a sticker on phone's back.
3) IMEI SV: shows"03".
Where can I learn more about EFS issues? Are there tutorials?
As you say I haven't done any backup thing.

Hi again Steamer:
After reading quite a bit about EFS issues now I understand much better what you meant with your post.
And as you said I didn't back up efs folder, I even didn't flash any ROM yet in the unit. The only thing I did was a 'hard reset' to the unit using the Power + Vol. Down method, after having several 'com.android.phone' errors due to backing up data from Titanium.
The phone went to factory state, I put the sim card and everything went back to normal again, meaning that I was able to make and receive calls. Like 4 hours later the phone went to emergency calls only mode, and from then on I'm not able to take it out of that mode.
So I wonder if the efs folder could corrupt after that factory reset. Is it possible?
Thanks again and any light is greatly appreciated.
It is not in its own partition on this device, but in system. A hard reset shouldn't have caused corruption, but it is not impossible. Your IMEI is intact then, that is good. From what you said about it working partially, your EFS is most likely fine as well. There is a thread here to get files with custom recovery zip file, or you can use adb commands to do it yourself. I don't have guides off hand, but Google is your friend, just specified this phone in searches. Try a new SIM. Sounds more like SIM /carrier issue now as you are out of "activation". That is why emergency is popped and unknown number. The SIM itself may and most likely is bad(or carrier has an issue with your account), in turn it can't communicate with the server causing non activation on network search. Priority to SIM.

I had the same issues. Bought in Us using now in India. Go to settings..tethering&networks.. mobile networks... international data roaming and select standard data. Switch off and switch on your phone .
This will happen when you use, internet over gsm. If you disable internet or if your phone loses signal while switching between edge and 3g/4g data, this is tend to happen.
Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Try my APN settings to see if it helps, but locations very important

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!
It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.
I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.
Having the same issue with radio. Just replied to your post, Kalash.
Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.

LG G6 Mobile data issue

Hello All.
This may sound like an easy problem to solve and a part of me hopes it is. but im fairly well versed in android and has me baffled.
Phone runs beautifully 870DS. When i leave WiFi, the swith to mobile data takes for ever and then remains super fickle and intermittent. I sometimes do not have any data moving whatsoever (offline dinosaur in chrome level) When i connect to wifi again, all is fine, instantly.
I have full signal (full bars).
Mobile data on.
Switch to mobile data on.
The correct network registered & the correct APN for that network is set.
I have it set to GSM/WCDMA/ LTE auto
I have tried setting RAT set to every possible combo and it still continues!
I read somewhere it could be caused by radio initiation, so i went in *#*#4636#*#* to run a ping test but "phone information" throws up an error "This application does not work on this device"
Im 95% certain it is unlocked because i I bought the phone in another country and just popped my new sim straight in without hassle.
The mobile data issues started almost immediately. Now im stumped as what to do.
Any suggestions would be greatly appreciated and rewarded with beer :good:
THANKS!!!
In Developer Options, try switching on the "Agressive WiFi to Cellular Handover" option.

Thanks. I will try that and trial run it over the next few days. The issue also occurs randomly while out on LTE or 3G. I will take my phone out to check google or whatsapp and nothing will send. So as your suggestion may be a work around, i doubt it will be a solve.
Will let you know how it goes

Does the phone have the right bands for 4G in your country?
Thanks for the reply!
Not sure, how do i check that?

go to settings, system, about phone, hardware info and check the model number.
For example I have LG-H870 (European bands, single SIM model).
I see you have dual sim so probably model H870DS and this should have enough bands to work well in Europe and Asia. Check here:

Thanks for that. Yes according to this https://www.frequencycheck.com/carr...0ds-g6-dual-sim-td-lte/mtn-group-south-africa
I do have the correct bands. Could a carrier lock only one of the slots rendering it single sim in effect? The one sim works perfectly, second sim, no dice
Sorry for bumping an old thread.
Gf is having a similar issue on her phone; long story short, it happens that sometimes, after being connected to Wi-Fi and turing it off, it takes ages for her to get a mobile data connection, despite having full signal.
I had her replace the SIM, as I've seen similar problems (intermittent data connection, phone appears connected but no Internet available, etc.) with a SIM card that was about to go bad; it didn't help. Next step would be a full phone reset.
@deathcells : did you find the cause of your issue?
@fagentu.xda
No unfortunately not. I just deal with it. Extremely frustrating standing in the shop trying to pay without internet...
I tried the settings and force options to no avail.
I tried using both sim cards (from different providers) in both slots for months and no combination ever worked for me. I have yet to figure out if i bought a dudd phone or if a work around exists. Please let me know what you find out! Thanks and best of luck
Have the same issue with mine now. It started to go bad a few weeks ago... Tried everything. Changed SIM card, factory reset, etc... and nothing will change.
I'd say that the phone is just faulty. As I'm still under the warranty I'm in contact with LG to find out about a possible fix or phone replacement. I'll try to keep you posted.
Have you guys find a solution for this? I cant do anything. Does flashing kdz to andriod 9 pie helps?
