Hi there
I've faced a problem since. I lose my antenna signal (on both 3g & 2g or auto connect) frequently, then when antenna signal bars return, suddenly screen flashes to black and back then I lose antenna bars again. and this happens for a while till it gets restart almost every time this happens.
I see multiple wired things also; while screen flashes,
sometimes some apps would stop working like instagram, battery docter, goole & google gesture and ...
sometimes i see a notification stating my sd card is damaged and needs format! (some times sd card is empty!)
and like that...
while restarting when samsung logo or even note 8 logo comes up, I see these flashing screen continus
I guess these happens while I am at areas with not very satisfying signals, although I had this problem while I had no sim card in it too!
what is wrong guys?
Note 8 5100
android 4.4.2 official ROM
(I thought of it as a software problem and upgraded to kit kat but no chance!)
I am also experiencing similar issues.
Sudden signal drop, screen flickering, rebooting without prompts. After that the apps installed in the sd card wont load for most of the time.
Plus device overheating and battery draining (did the battery pull trick and have been doing ever since, sometimes 2x a week!).
really hope somebody could chime in for a solution.
PS, thinking of flashing new ROM, but havent decided which one yet. Will this help at all?

Donno... I know if the battery is weak or bad, the screen will flash randomly when power is needed. Example 1600mhz is used durring boot and home screen loading. As for non wifi connection for data, that will consume power like the CPU running at max.
It may be time to replace your battery. Especially if you have pulled the plug a few times. The wires and plug are brittle. Found out when messing with the used Note 8.0 I got on ebay that had 4.4.2 loaded.
i was using my zf2 as usual. suddenly it became unresponsive. i locked my phone and kept it in the pocket.
It started heating like never before. It went on restarting again and again, and battery level was plummeting.
i simply did nothing and switched it off.
Later i switched it on, and the home and the recent apps buttons were not working.
no sound could be heard,
no phone calls can be heard,
factory reset is unfunctional.
Please help as to what do i do?
Try to flash the stock rom if you can access recovery, there are a lot of guides around, if it does not work send it in for service.
Hello,
I have spent many hours attempting to solve the ongoing problem of the wifi button not responding but remaining gray when touched. Here is a quick chronology of symptoms and attempted fixes. I love everything else about the phone, especially the size, but am close to throwing my hands into the air. If anyone has any suggestions as to a Rom that may finally fix this, please let me know!
Wifi worked fine on phone for about 6 months, then became unreliable, not connecting after being out of range and coming back into range of wifi stations. I was usually able to force it to come on by a reset, pulling battery, turning off mobile data and calling *#0011# and turning wifi power saver off and on several times.
After this would no longer work, I rooted phone with CF-Auto-Root-jfltetmo-jfltetmo-sghm919.tar.md5 , was able to use wifi for a day or two, then nothing would force it on.
Tried multiple custom roms, including CM11 kitkat and CM12 Lollipop, same results, I would originally get wifi to fire up and connect, but after a day or two max, nothing.
Have flashed stock kernel for modem, nothing.
Took back of phone off, unplugged and plugged in blue antenna wire, nothing.
Recently flashed M919UVUFNH7_STOCK_ROOTED_DEODEX_KNOXLESS along with NH7_modem.tar.md5, wifi worked a little while, and as usual, wont respond to any resets, battery pulls, etc.
Thanks for any help you may be able to afford.
ive been having the same issue or a month or so now... cant seem to find a sulution anywhere. I too tried multiple roms, even the new 6.0 . I cant imigine its the wifi antennae because it works fine when it wants to... gettin frustrated with it.

I agree, flashing stock firmware is one of the first things that should be done in this case

I have a suggestion. Use the following link to get latest T Mobile firmware for the phone.
http://forum.xda-developers.com/showthread.php?t=
Sometimes it takes flashing the firmware twice for the full install of the radio to take properly.
To begin, remove the back of the phone, because your going to remove the battery after the first flash.
Boot into download mode by holding the volume down and power.
Assuming you know how to use Odin, before starting the first flash, unchecked the auto reboot option.
After Odin has reached the point of RESET, unplug the cable, remove the battery... Replace the battery, reboot into Download mode and
repeat the process, leaving auto reboot checked this time.
You are now completely stock. Your data will be basically left untouched.
Good luck.

Have you tried cleaning the hardware contacts on the antenna? I remember this same scenario on my old HTC Desire... the antenna contacts were dirty IIRC and they needed cleaning.
Wow, so I am not the only one still facing this issue! I flashed this rom http://forum.xda-developers.com/showthread.php?t=2539361 a few times and I eventually noticed the wifi issue as well.
Baseband: M919UVUF0H3
Kernel version: 3.4.0-2437203 [email protected] #1
Build number: KTU84P.M919UVUF0H3
Here's what I attempted:
1. Did a full wipe on the phone and installed full firmware 4.4.4 http://forum.xda-developers.com/gal...mware-firmware-kernel-modem-recovery-t3193835
2. Flashed stock kernel from the same link above
3. Installed SuperSU, flashed TWRP
4. Installed and ran TriangleAway to clear KNOX counter
Same issue as OP--at first wifi would work but the connection would not stick and I was unable to activate the wifi button anymore. I tried uninstalling KNOX but I get an error "Failed to create KNOX mode." When I reboot into TWRP, I get the message "E: failed to mount /efs (invalid argument)."
I discovered that my EFS folder is empty. I don't have a backup. Could this be related to the wifi issue? Am I screwed?
Finally got the wifi working. Took the white shell that covers the board off and cleaned the contact on the shell with a q-tip and isopropyl, but it looked kinda scuzzy so I scratched it a bit to expose bare metal again. Then I went to the board side and pulled up on the tiny piece of metal that springs to make contact, enough to bend it to a steeper angle for better contact. Wifi and BT working steady for over an hour now. Thought id share.

Heres a link with pics of the locations of the antennas
Edit:
though the wifi worked briefly after this, it stopped working shortly afterwards... back to square one...
Hi everyone,
I'm having serious problems with my Wi-Fi on my Samsung Galaxy Note 3 Neo (SM-N7505). Whenever I click the button to activate the Wi-Fi, the icon goes from grey to a dull green (darker than the bright green which signals that a function is turned on), as it does when it's trying to turn itself on. Problem is, instead of turning on, it just stays in that state for a few minutes before reverting to grey. This has gone on for a while, and I've already tried several possible solutions which I found after online searches. I don't think it's a hardware issue (see point 1 for the reason), and I really hope it isn't, because my warranty has been voided due to rooting, so I can't have my phone replaced or repaired unless I pay for it (which I can't at the moment). So, I'm basically ignoring the possibility of hardware failure and trying every possible software solution, hoping one of them will work, otherwise I'm just stuck with no Wi-Fi. These are the fixes I've tried:
1) Take out the battery while the phone is on, wait a few seconds, then put it back in and boot the phone up. This used to work when the problem first presented itself a few months ago (which is why I don't think it's a hardware issue), and I've been since using this method to fix it whenever it happened again. But a few days ago, this method stopped working for whatever reason, so I was back to square one.
2) I tried renaming the data/misc/wifi/wpa_supplicant.conf file, which seems to have worked for some people, but not for me.
3) I tried updating the version from Kitkat to the recent Lollipop, hoping that would fix it, but nope.
4) I tried deleting practically every single app one by one, hoping that one of them was interfering with the Wi-Fi somehow, but nope.
5) As a last resort, I tried a factory reset, but not even that worked.
This is basically the long and short of what I've tried to fix this... I might've skipped a few of the simpler fixes I tried (for example, I just remember I tried disabling "Smart Network Switch", which seemed to do it for some people), but the big stuff is all there.
I'd really like to get my Wi-Fi back, so if anyone could help me fix this thing I'd be really grateful!
Thanks in advance to anyone who will bother to reply.
same problem dude
Same problem...wifi and bluetooth not working...pls help us
Same Problem for me, Initally it works fine even after updating Official Lollipop update (OTA), but after few months now wifi & bluetooth are not working for me. And finally faced battery drain issue for past few days. Battery goes down upto 20% per hour even in idle condition. Then i rooted & installed Note Rom & even after i face the same problem. Is there any way to fix?
Hello,
Since 2 weeks ago my phone has been started acting all weird. It started with my Phone freezing and restarting itself one morning. It showed the LG logo for a few seconds, then went black and the same thing repeated. LED did not start blinking at first but after a few loops the LED came on, the animation played and phone turned on nicely. No more such problems during the rest of the day.
Fast forward 2 days. It got worse. The freezing and restarting happened more often and at one point it was in the LG logo -> black screen -> LG logo loop for a good 10 minutes before it booted. It also drains my battery about 10% every single time.
So I decided to do a Hard Reset when I managed to keep the phone running long enough. The hard reset process itself worked flawlessly, no issues during the reset what so ever. I though the problem was over until a few minutes after the hard reset when I was reinstalling my apps, it froze and restarted again.
I started googling about the issue and found a few matches. Some people suggested replacing the battery and some suggested putting a piece of paper between the battery and the SIM card slot from which I did the latter. That actually worked for a few days until the reboots came back and it got worse by the day when it finally was completely unusable since it kept restarting after booting up (usually it didn't even get to that point). Then I decided to try a new battery because it was the cheapest option available at that moment.
At first all looked good on a new battery but still, just a few minutes after rebooting the phone from a new battery it froze yet again and restarted itself. So 25€ wasted on nothing.
At this point I'm starting to run out of options and really would not like to buy a new phone since my G3 is only two years old (warranty just ended in October 2016).
Any suggestions are more than welcome at this point.
Best regards,
Taavi
Yesterday I tried flashing the stock V30B marshmallow ROM onto the phone using LG flash tool 2014. It lasted without restarts for about an hour and then it all started again.
So in conclusion:
A) It's not the battery.
B) It's not the software.
C) Thus it must be the hardware.
Since my warranty is void already, the repair costs would probably be quite large.
I think the only chance left for me is to suck it up and buy a new phone.
It was fun while it lasted though. RIP.
Funny thing is that after I removed my SIM card, the issues have stopped for ~24 hours. Yesterday I was able to browse reddit and watch videos for almost 2 hours straight with no issue when I had no SIM card in the phone. I will try inserting the SIM card again after I have fully recharged it to see if maybe it has something to do with the SIM card connection.
Put in the SIM card and it didn't even last 24 hours before restarting. Took it out again. Unfortunately it now restarted even without the SIM card so it still must be some hardware failure.
Same issue here. Changed battery, factory reset, rooted and TWRP+CyanogenMod 14.1 flashed and SU granted.
Constant reboots. Sometimes bootlooped until I remove battery
Having the same problem. Tried new battery but it turned out to be a cheap clone that was worse than old battery. Got another from mbuynow which last longer but still restarts but not that often. Tried the paper trick to to avail. Also tried the LG suite to see if it helped but no luck. Running marshmallow 6.0 and have done a full reinstall. Is this likely to be hardware problem?

Cannot tell for sure but seems it is a hardware problem which is really sad since besides the restarts the phone is still in very good shape. I would take it to repairs but as my warranty is already void it would make sense to simply buy a new phone and sell the current one to parts.
I have the same problem... I flashed CRDroid or something with Android 7.0, it booted normally, but then, restart after few minutes... It can boot normally with the usb to computer, but not with charger. It can also boot to twrp, wipe, install and fix the system works, installing other roms works too, and they can boot normally, but it shut down, as soon I remove the cable... I thought it was nougat rom, it change some in system files or drivers like battery options... I'm out of options...

Seems like a battery issue I think you need a new battery if it's working without the wire plugged in

I have 2 phones. This thing seems to puff exactly after 2 years coz they were bought in difrent times and both of them emerge this issue after 2 years for each. boootlops were after few minutes from start. In case of first one new battery was a bingo but i did not investigate second - im going maybe for new phone. Funny thing. Maybe product life time was to planned to good(for producer)?
I was a great phone, longest I have and most customised... Very agile, never had bricked, bootlooped or failed to flash... Thank you for your great support, LG G3.... Rest in Peace... If someone can bring it back to life, I'll be back to that.
I'm counting on someone stumbling on a fix as well. It's still an awesome phone expect for this stupid thing.
I had similar issues but I realized that different SIMs seemed to work with the phone. Went to my carrier and requested a new one. Since then, no issues. Maybe something with the sim card slot?

It happens even when my SIM card is not in the phone. It could easily be the SIM card tray but cannot confirm without taking it to repairs.
Did you try disabling Location?
(I had random reboots when the battery went to 25% and when i disabled Location services,it got fixed)

One of the hard resets I did was from full charge and I didn't enable anything, including location. It still went into the reboot loop.

It might be a hardware problem in some LG G3 phones.
It began rebooting and bootlooping after 2 days,that i had disabled the location services.
Now i'm thinking of getting a new battery but i don't really think it will do any effect..
So i might buy a new phone..

I had the same problem as you,i bought a new battery and everything got fixed.(you need exact the same Model of battery so when you go to a store note the model of the battery)
Temporary Fix
1- Remove the SIM, turn on the phone, put it in Airplane Mode.
2-Insert the SIM turn on the phone.(Don't change Air mode).
3- Turn off auto backup/restore in settings.
4-Go to network setting>Preferred network Type.
5-Turn Off the Airplane Mode and immediately SELECT THE 3G only(Before it catches the signals), in some phones WCDMA only.(Do not Select 4G/LTE/2G).
6-Done
7-Restart the phone.(Now it will not reboot)
Drawbacks:
In 2G signal zone, There will be no signals.
Its a hardware problem,But its a way to trick it.
