Wifi down after flashing wrong kernel - LG Optimus G Pro

Hi guys,
My wifi is completely down, for 5 days, after flashing this kernel
It is for stock ROM and I realized only too late and I was on CM11. The author made no mention of that in his post as well. What can I do to resurrect my wifi? It just says "turning wifi on" in wifi settings, and doesn't turn on.
Will a factory reset solve this? Or reverting back to stock rom? I'd rather not do these as I'll need to redo my homescreens and folders again. Please help, thanks!!!

I'm afraid my frnd... u need to flash stock again using LG flashtool..

Radio Data Wifi HELP

Hey all,
Ok, I started having issues a few days ago with my SMS/MMS and I notice at the same time I was getting poor Wifi / Radio service. (Custom ROM's)
Well now it's gotten worse, I just attempted 2 different ROM's (both cm10.2 based) and was unable to get a Radio signal, Wifi wouldn't function at all, and no data at all. I came from a fully functional stock (ZVC). I did try switching some settings in Data / Wifi and etc back and forth as well as reboot and etc, also tried a freegee fix / restoring of the EFS and nothing helped.
Can't really stay on the ROM with no service as I do need to be able to use my device, so I am gonna have to restore my Stock img and perhaps if some help is posted I can give it another shot.
Thanks all!

This may not help, but it won't hurt either. Try flashing zvb modem. Look in the teeny bin thread.
Zvc and zvb modems seem to be the same. But who knows.

WIFI will not turn on

Hi guys i have a lg g3 that has been running fine on kitkat
it the received the lollipop update OTA and all went fine apart from now it wont turn the WiFi on
you can click it on and it moves to on but seems to be always trying to turn on..?? without turning on.?
any ideas..?
I have done a reset etc still no joy
Did you try to reflash? (I think that you mean by resetting that you full wiped your phone and not reflashed the rom)

Same issue here.
I get around it by forgetting network then just signing in again. Wifi works perfectly until I leave the house and return later. Then I just do the above and viola, working wifi.
I've checked with speed test app and wifi is definitely working.
Funny thing is, if I switch off wifi then turn back on it also works.
Only when ive left home and returned later does this bug arise.
Hello guys,
This thread is a little bit old, but I am curious to know if you found a workaround for this issue.
I have the same problem as the OP (not at the second poster): since I received Stock Lollipop the WiFi won't turn on. When I try to, it says "turning on" for a while then acts like it is off.
I just bought my LG G3, NCIX the reseller, refuses to refund me or replace my phone...
I performed several factory resets and tried to flash different KK stock Roms. The weird thing is that the WiFi works with KK...
Thanks for your help.
Identical experience here.
I recently got a D855 16GB, which was on stock unbranded V10a, jumped through several OTA updates through V10g, V10j, and V10k (IIRC) all with wifi working fine before getting the lollipop upgrade OTA for V20c.
Immediately wifi will not switch on - the switch itself is on, but with the off section a lighter grey compared to the bluetooth switch.
On the wifi screen itself it says "Turning Wi-Fi on..." but after a while the switch reverts to off.
It's now had OTAs to V20e and V20h, but wifi is dead on both versions.
Note that this is stock and unrooted (never rooted) so I can't believe it's something I've done. Next trick will be to root and poke around /data/misc/wifi.
Does bluetooth work or the problem is only with the wifi? I also have the same problem, wifi, bluetooth is not working and when I check in the settings the mac adress it says "unknown".

Accountability
Unfortunately this isn't a unique problem. There have been countless bad updates from multiple manufacturers. In this litigious world, I'm surprised no one has sought damages for bad updates that effect usability.
I have the same problem from yesterday. wifi and bluetooth seem to be turning on but they never turn on. i've done many factory resets but it didn't work. has someone found a solution?
^^^ Exactly the same issue. Would love a solution!
Same issue. Tried Hard and soft reset and have also updated firmware using LG Mobile Support Tool but had no success.

ok, after 24h with this problem I think I got it back to working. Let me explain what have I done:
1. Mine is a dual sim model, that I bought in hong kong by the end of 2014.
2. Yesterday, I removed sim #2 (no longer needed), without removing the battery. I had a couple of messages indicating to restart the phone, blah blah. Can't remember if I finally restarted it or not.
3. This morning I saw no wifi connection in my phone, only 3G. Tried to start wifi in the quick access menu, but this kept blinking, never starting wifi. Restarting phone... nothing. turning off bluetooth... nothing.
I figured out that the problem had to be related with the SIM as this is the last thing I had done with the phone. Thus, I tried this, with success:
4. I turned off the phone, changed sim from slot #1 to slot#2 and started the phone. Wow, it worked for some minutes, then stopped, then started again. Well, a good sign.
5. Changed again sim from slot #2 to slot #1: Wifi working again. After some time it stopped working, but soon started again. Hasn't given me more problems (after only 30 min, that's true).
Hope it helps.

HELLO
I have exactly the same problem and I think we're not the only...
D855 :
-Wifi and Bluetooth doesn't work.
-Wifi keep turning on itself and the battery drain..
-3g/4g works perfectly.
-Downgraded on kk and Wi-Fi works so it is not a hardware issue
-Even on fulmics Rom Wi-Fi and Bluetooth doesn't work
HEELP ME PLEASE
Got the same problem here. I have my G3 since november 2014 and recently I rooted it to install CM 13 on it and Xposed bcs I got tired of the laggy software of LG. One morning I woke up to drink some water and saw my phone restarting a lot of time... ok I thought its a simple bootloop. Tried to install CM again, didnt fix it. Flashed stock software and still... Bought new battery and new power flex and the problem is still there. I go into download mode, installed the software with LGs support tool and got pass the bootloop, but now wifi nor bluetooth works. I thought it's the software so I dared myself again to root it and installed TWRP and CM13, but it wouldn't boot. I installed then Liquidsmooth, based on CM13, and got it to boot up, but in the configuration menu where WiFi is needed to be added it couldn't turn on. I skiped it and in the middle of the process it started again to restart. I don't know if it's a hardware based problem or software... But I would like to try everything out before I have to buy a new phone.

Have you maybe tried to change the kernel of your device? I have never done that so I am scared if I would damage something.

Here someone says it's the kernel that is having problems and installing a new one and going maybe back to the old one will fix it.

I installed CM13 and in the setup screen I actually had wifi and I could connect to my router. It was kinda strange. But bcs I have some problems beside wifi, the reboot thing, I couldn't test out if it works too. Try flashing CM13 or ROMs that are based on it like Liquidsmooth. Maybe it will help.

Mobile data not working +STOCK ROM

Hi everyone,
I have LG G3 d855 (Europe version). I bought it online, not at any network. I had an lollipop update really fast (Poland). Yesterday I rooted the phone, it worked fine, and installed the BlissPop rom. I missed the Quick Circle option though, so today I installed the ChupaChups rom for lollipop. And now my problem: The mobile data connection is not working. I can make calls, send texts, connect via wifi, but the data connection over the network is not working at all. I went back to stock - I downloaded and installed the European version using kdz method, it didn't help, so I did it over LG Flash Tool. It still does not work. Do you have any ideas, what to do with this? I feel like I'm going to cry, I'm very nervous about it, because I use mobile data almost all the time...
Maybe there's something wrong with the modem driver? I really hope someone is able to help me. Thank you in advance!
Edit: Maybe I used the wrong stock rom? I don't even have the option to update to lollipop anymore.

Seems like a modem baseband was flashed somehow.
Flash the modem back to the correct stock version you had and it should fix the problem

Do you know where I can find those modem drivers?
Edit: I checked which version of software I should use with my IMEI no. It's 20h. Would it be enough to flash the stock rom over kdz, or do I have to find somewhere the modem driver for this version? If yes, do you have any idea where can I find it?
Thanks.

Not sure.
I have the G2 and we have these files in our Development Section where you find ROM files etc.
Should be there as flashable zip files in the same section for the G3

Ok, thanks! Last question before I do the final step - I have the ROM I am supposed to have. I rooted the phone, installed TWRP. I've also found the modem driver for my rom. And the question is - how should I flash the driver? Should I mount system or do anything apart from just installing the zip? Should I clear any cache?
@CaPlanePourMoi Wipe the modem partition in Recovery and then just flash the modem zip which will replace it. If that doesn't work, you can go back to BlissPop that includes it's own Modem and install Xposed for 5.1 Super-Alpha and the QuickCircle Mod for AOSP, all 3 of those I'm using with no issues whatsoever!
So I installed the modem driver (20h) yesterday, but it didn't help. I decided to install the BlissPop ROM, and mobile data (with LTE) works just fine. I will go back to the problem on Saturday and keep you up to date. Thanks!
Update
Update: Hey everyone - it seems like I didn't find any solution. I tried to go back to the ROM based on stock again (it was Cloudy this time), but the modem still didn't work. It was acutally working for a few seconds (I had 4G connection), but then again it was lost and it didn't connect anymore. Wifi works fine. Do you have any ideas on how I can flash the modem correctly? And how can I uninstall the modem that I have now in recovery? I didn't do that, because I cannot find this option.
Thanks in advance!

I have a very similar issue
my LG G3 is the D855 on AT&T , and was working fine on Cloudy 2.2 or 2.3 Lolipop without any issues!
All of a sudden last Friday 5/22/2015, mobile data stopped working, but WiFi is still okay.
I just did a full wipe, updated APN, and the issue still there
I haven't change any major things in probably 2 months, not sure what's going on.
Finally, contacted AT&T, and made sure that they remove from the network,a put my back(troubleshooting). As well as changing the sim, and APN, but nothing worked!!
PLEASE HELP!!!!!!!!!!!!
UPDATE: So my last attempt, I contacted my provider AT&T, and they requested to try a default APN settings, even though what I used was working fine.
I did, and immediately my mobile data was back!!
Everything is working back as normal, and for some reason the network APN required updating
Did almost the same few days ago! I have finally solved my problem. Here's the explanation:
In Poland we had a network called "Era", a few years ago it was bought by T-Mobile. I searched the internet for T-Mobile APN settings in Poland and it didn't work. I have also found the APN settings for the old network, "Era" and surprisingly it's working. I don't know why T-Mobile settings don't work while they do for other people (and at this point I'm too afraid to ask. )
HI, i have the same problem on my d855 with wind (i'm in italy), i was rooted with custom rom and when i came back to stock i lose data connection. What i have to do? what do u mean for restore default apn? the default of my carrier? or the default for g3?

WiFi will not turn on...

Hi. I have a Sprint Samsung Note 4. I was getting a screen overlay error and decided now would be the time to change the ROM on the Note.
I followed the steps from "How to Install CyanogenMod on the Samsung Galaxy Note 4 Sprint ("trltespr")"
After I installed the first ROM, which was the latest nightly, and booted it up, I noticed that the WIFI says "Turning on" but doesn't ever turn on. It's greyed out in settings as well. I tried a few different nightly's thinking it was a defective file or bad install. Still no fix.
So then I went http://www.grantbarker.com/samsung-galaxy-note-4.html to try different roms, and I get the exact same issue.
Now I'm thinking that there is something I'm missing that the original ROM had. And for some reason the backup I made from it is missing, so I can't go back to it either. Is there a way to fix the wifi? It kind of sucks without it. Thanks for any advice that could help.
Were you on Marshmallow or Lollipop stock? Sounds like you have the wrong bootloader and that may be the reason. You would either have to flash the recommended stock tar or bootloader or bootloader and baseband.
I don't keep up with CM but the thing to check for is recommended bootloader in OP or search the thread. You may find it necessary to flash OK1 or OG5 bootloader. Dunno, maybe check for the baseband too for CM.
There's a bootloader and baseband thread in the development forum for Sprint Note 4. You should find what you need to flash in Odin AP mode. The ones labeled firmware are bootloaders.

You could probably try reverting to the factory settings and checking if the WiFi works? And then, you could change it to the current ROM again. This might help you resolve the WiFi issue.
