Hi,
Since a couple of days my Desire won't register on the GSM network. The sim is working fine if I put it in another phone, so that's not an issue.
The message I get when trying to manually choose my network is "Your simcard does not allow a connection to this network"?!
After some browsing on the web it seems that this happens sometimes but I cannot find a way to get it resolved. One of the tricks should be to manually toggle the network mode to GSM only or WCDMA only. The strange thing is that when I try that the phone instantly swithes back to GSM/WCDMA auto. To manually change network mode is not possible. Is this an indicator that something is wrong?
I have tried to re-flash the rom, installing the latest radio, toggeling flight mode on/off, etc.
What else can I do get it resolved?
Currently running my rooted Desire with:
LeeDroid 3.0.7
Radio 5.17.05.23
Appreciate the support!
Thx!
Anders
I think you should try the offical RUU .. than you can make out if it is a hardware problem or software.. make sure to prepare all thing while your phone is in working state, before flashing offical RUU make sure u have usb debbuging enabled, adb driver working. and a goldcard..
I've been using DN3 V.3.2.1 on my N7100 (Galaxy Note 2) for some time, and noticed that the wifi (along with portable hotspot) didn't work. There's this wifi fix to install via odin to fix the problem.
The thing is, before DN3, I've flashed stock 4.3 N7100XXUENA1, without knowing that it comes with new bootloader. The new download mode restrict any rom installation except the stock 4.3 (though recovery and root installations is possible, dunno why) with an error : UNSUPPORTED VERSION
EDIT : The wifi works, but if I toggle portable hotspot, the hotspot can't be turned on and then when I try toggling wifi, it can't be turned on too. The only workaround is to reboot the phone to make the wifi work.
Is there any way to fix this? Since my main internet source is from my phone so portable hotspot is a must. Thank you and sorry if this has been asked before.

After update wifi icon start blinking and after 5 mins displayed message 'searching wifi network'. but nothing happens, it even unable to display networks list. all solutions at forum (clear data for apps) are not working. Thinking to go to lg service center.

Not sure what's going on with your connection issues, but the MAC address will only show when WiFi is on.

Hello, I got the same problem and I maybe found a solution !
Thats what I did on my LG G4:
- Turn the airplane mode ON
- Reboot the phone
- Turn the airplane mode OFF
- Go to wifi settings and if the wifi is not activated, turn it on
- If the bug persist at this point, do the process again
This happened to me on Sprint variant. Did a factory reset and never got passed the Google setup. Had to return the phone
Anybody ever find a solution to this problem? I have contacted LG repair service but I have heard nothing back from them. Not what I wanted to do as my bootloader is unlocked...

Hello, have you
Tried resetting phone??
Tried rebooting router??
Yeah, flashed a stock 5.1 kdz to see if it would help but still the same. I had flashed a 6.0 rom and it was working for a day and then the problem started. Flashing back to stock 5.1 didn't help.
The phone is getting picked up tomorrow and will be fixed within 5 to 7 days according to the email from LG. I just hope they will fix it because of the unlocked bootloader...
same problem here. very disapointed to lg. i heard that this is harware problem.
wifi icon keeps blinking. no warranty at all. bought in korea.

Just wanted to thank you for this. Ive had this same damn problem for 2 days and this worked as a workaround. This was the second time the bug surfaced, the first time resolved itself after a day and a system update that was pushed to my phone right before the bug started. It was already downloaded so i just installed it and the bug went away. A week later the bug surfaces again and Im pissed off ready to take my phone in and i stumble on this. IT WORKED! Thanks again.

I got this to work on my Wife's G4 when it was having the flashing WiFi issue, well, sort of. In addition to switching airplane mode on I had to toggle bluetooth and NFC, then all the sudden WiFi connected and stayed that way. I then rebooted and turned airplane mode off and everything seems to be ok now.
I have the same problem after updating my LG G4 to 6.0. The wifi is flashing and mac is bogus: 02:00:00:00:00:00. Bluetooth is also unavailable.
I contacted LG support and they told me to factory reset the phone. This did not make a difference.
Any updates on how to fix this?

Thanks AymericM!!!!! This was driving me mad, and your strange tip worked, i can´t believe it!!
Rebooting is just a temp solution and doesn't always work.
No dev here have any permanent solution?

Activate Developer options - tap Build No in About a few times
then in Developer Options - >> User legacy DHCP client
Reboot and try to connect
So the problem I'm having with my G3 is that the Network either drops and comes back repeatedly or completely drops and does not return. This only happens on 4G. When I go into network settings and change network mode to 3G it works fine and I get a constant signal all the time.
I have been using Fulmics ROM and I thought maybe that was the issue. But it wasn't.
I tried 3 different sims from three different carriers (Three, EE, O2) on several stock firmwares. (20N, 21C, 30A, 30F).
Each scenario is the same; network drops when phone is on 4G network mode, but its fine on 3G mode.
However, I have noticed that if I leave Wifi OFF allowing 4G data to connect first, then its fine. I can even turn Wifi ON again and the network is stable. I can even turn Wifi and Data OFF and the network is still stable.
But, if I toggle aeroplane mode, where Wifi connects first or where Wifi and Data is turned OFF; I am back to the network dropping.
Also, I live in London UK so there should not be any signal issues. Can anyone tell me why this is happening. I doubt it's software issue as I've tried several firmwares.
Any help is appreciated.
Mate I'm afraid there is a high possibility it's the Fulmics ROM.. I'm still trying to read up on the issue myslef, there's a ton of reports in the Fulmics thread and around.

I'm using an UK bought LG G3 as well (from Three) and started experiencing similiar issues after I flashed Fulmics. Even tried rolling back to 4.4.2 using a .tot file but didn't really help me.
Still scouring all around trying to find how to fix the issue..

Hmmm looking back now this issue did start when I first installed fulmics 3.5. But shouldn't everything revert back to stock when you reinstall stock firmware.

That's what I thought but I guess it's a little bit more tricky.
Anyways I think I managed to restore some kind of stability in the signal, still unsure about the process though. Seems that different stuff are working for different people. In a few days I hope to have some information to give you how to fix it.
In the meantime try checking the Fulmics thread for ideas and suggestions (that's where I start off from).

Yeah let me know when you find a fix. Really appreciate the help.
One thing that is sort of a temporary fix for me, works on Three, EE and O2 (only ones i tried), is connecting Data first when on 4G mode.
So if I toggle airplane mode and if Wifi connects first then the network drops or keeps refreshing.
But, if I leave Wifi OFF and Data establishes a connection; the network is stable and I can then turn Wifi On again and the network will remain stable.
I just have to make sure the network does not lose connection (i.e. tunnel or airplane mode), and if it does ensure Data connects first.
Also, another thing. After I reinstalled Fulmic 5.3 it seems 4G mode is sort of stable. As in when on 4G mode instead of dropping the network it connects via 3G automatically. But this only happens with Three.

Okay here is what worked for me - open this guide and download the Three specifiic Lollipop and Marshmallow .kdz files.
Flash the stock Marshmallow firmware first using the LG Flash Tool method. Your phone probably won't automatically get recognized since you're running Fulmics now so you'll need to change the COM port as described in post #
After that downgrade to stock Lollipop using the LGUP method. Personally I downloaded more updated (I think, not sure) files from here.
Then I proceeded to re-root and clean install Fulmics 5.1 and the 5.2 and 5.3 OTA updates from recovery. Booted and network works without drops now with 4G connectivity.

I changed my carrier and got an automatic SMS with configuration for my phone and instructions to save it. I should've known something was fishy when I recieved the "congratulations for setting up" message even before I recieved the actual settings. Anyways 4G was running fine on my new carrier with 32 mbps speed which is okay, much better compared to the same carrier 3G network, however I only had 3 bars of connection so I gussed what the heck, I should save that configuration after all, it might make things better. What a bloody mistake. I lost 4G connectivity and my phone refused to connect to the 4G network, only 3G (just as you describe).
What worked for me in this scenario was wiping the cache and dalvik (not really sure this step is even necessary to be honest, but I was headed for a full rom re-wipe anyway and decided to try with this first), going into the hidden menu and choosing LTE only connectivity (Fulmics Tweaks -> Hidden Menu [or the hidden code for the phone app if you decided to stay on stock, which I dont have] -> Modem Protocol -> RAT Selection -> LTE only. At this step my phone got to the usual 3 to 4 bars of connectiviy but was displaying "Emergency mode only" and no data at all. I proceeded to Settings -> Networks -> More -> Mobile Networks -> Access point names -> Reset to default from the menu. If network mode doesn't change back to GSM/WCDMA/LTE auto automatically, change it back manually. At this point I had restored back my 4G connection and everything is working normally (30-32 mbps connection stationary in my house through a wifi hotspot next to my laptop).
Good luck, I would follow the steps as described just in case. I tried many reflashes before that should've worked but didn't for me. However different things work for different people, hope this works for you and please report back

I'd like to thank you so much for this information! I was having signal drop issue after installing Fulmics ROM. Tried to flash stock ROM but no success. After doing the downgrade via LGUP method to LP my phone is getting full signal again (at least I didn't notice any drop until now).
Thank you!

Sorry for the late reply.
I followed your instructions and unfortunately it didn't work. :crying:
I first tried with the D85520f you provided and then with an updated D85521C firmware. But nothing worked.
The temporary fix, which I found works, is to ensure 4G mobile data establishes a connection first before Wifi (turn Wifi OFF then ON after data established). Then there is no signal drop until I go through a tunnel or phone restarts (signal drops completely), which means again i have to ensure 4G mobile data establishes a connection before Wifi or else it'll go back to the constant signal dropping.
Guess I'll just stick with 3G at all times. I've spent too much time trying to correct this than actually finding enjoyment in using the phone.
Anyway really appreciate the time and effort you took to help with this annoying situation. :good::good::good:

Can I just flash this modem? Have a link to the 21c modem?
Flash in twrp or send via LG flash?
