Hello guys,
I managed again to brick my phone.
I flashed Fulmics as I wanted to swap from those not fully stable nougat roms. Well, I have no idea what caused my problem - Fulmics run without prolbems for a 2 or 3 days including xposed etc.
Then today I changed my ChromePie options and that's when the reboots began. I don't know if this the real cause was though.
So I tried to flash another rom but always got random reboot even in recovery after few minutes/seconds. So I went all the way back to stock rom (4.4.2) with LG Flash tool - which worked after a few tries. Then I installed MM rom via .kdz file and flash tool 2014, which also worked after a few more tries. But then the reboots started again. Can't say if the 4.4.2 rom was without boots because I updated to 6.0 quite quickly.
The strange thing is that after some reboots phone won't boot again and I have to take and leave out the battery for some time to boot the phone again.
Any solutions for my problems?
Best regards
..bumped into the same 1/2 year ago. Didn't want to put to much effort so,..went to stock and back, worked for me.
Good luck.

Which stock and how did you go back?
As mentioned I already went back to stock but the issue kept occuring.
Hi, got the same problem with my G3
wi fi and bluetooth didn't work and phone loop rebooted
Here below the steps I followed to solve
1) First attempt (didn't solve): had cloudy rom, got back to stock official but still rebooting, tried fulmics and other rom but problem persisted.
2) second attempt (didn't solve): went back to stock and changed battery (found somewhere in internet), now I have a brand new battery but a phone still loop rebooting
3) third attempt (SOLVED): found that the wi-fi / bluetooth chip (one for both) copuld have unwelded and solved so (it appears I can't post outside link, delete spaces to have the correct link):
youtube .com / watch?v=1zWpzYh2DPI&t=15s"
youtube .com/ watch?v=6_0jzp65eLY&t=256s
Now i'm on fulmics and no more loop reboot
Hope you can solve
[sorry for my english]

have to say restoring and/or flashing isn't always that stable. I've experienced it sometimes needs a 2nd try.
Hopefully it isn't a hardware issue in your case.
So I tried all of oyur suggestions but nothing seems to work.
On the contrary I ended up in a status where I can't even flash a new firmware.
In LG Flash Tool 1.8.1 I get the error
"Donwload Fail!!!"

In LG Flash Tool 2014 (flashing MM with kdz file) phone shuts down in middle of process.
But I can still access Download Mode.
No more ideas?
I really think I finally broke my phone... But the fact that I can still access download mode keeps my hopes up.
So, after 2 months I just tried to reawaken my phone. Still the exact same problem. It just keeps shutting down aber some while, but just when I start flashing something. If it stays connected to computer whitout doing anything it can stay on for like ever.
Can anyone confirm that this could be a hardware defect?

Alright, so I just started using my OG on ringplus and decided to root with framaroot (I think I used gandalf mode). Anyways later on the phone started showing Demigod kernel issues (On stock zvc). So I went with Teenybin and flashed the unlocked bin using LGNPST. Same kernel issue. However custom roms don't show this issue. Now, the problem is I need to go back to stock so I can get to diag mode since my esn info got corrupted. Now this wouldn't be a problem since I'm alright with cdma workshop or DFS (I only want to repair the ESN), but of course I need to go back to stock. Any help is appreciated. Thanks!
EDIT: I should probably add that I have tried several roms, and several different bins (including full sized ones) yet I always come back with the same black screen with the Demigod kernel error. One more thing is that I have all the information that needs repairing, just can not use it until I get a working stock image.
Do custom stock roms work such as optimus DE or lifeless?
Also theres a guide somewhere on how to activate diag mode on aosp roms. Id link you but im on my phone. Should come up easily on searching the forums. i know theres a link to it in the irc chatroom.
Sent from my Sprint LG Optimus G on Page Plus.
Strangely aosp roms work fine minus service. I did try the guide, but for some reason I couldn't edit any of the efs settings even after I flashed the efs recovery zip they had. DFS and cdma workshop just bring up failed or errors when in diag mode. So far I tried DE, but I'll have to try Lifeless and see what happens. It's just so weird how the demigod kernel issue keeps appearing on stock and stock based roms, the phone freezes and reboots to a black warning screen.

Maybe try a stock rom with a custom kernel made for it like viper?

Try this thread... If you flash the teeny bin it will give you an unlocked boot and recovery.
http://forum.xda-developers.com/showthread.php?t=2230106
I think that might fix your problem. Grab the teeny and not the full. The full is huge and will erase your info and is not necessary.
Try that out and come back. I am all but sure it is related to the bootloader/recovery.

I probably should have said when I used LGNPST I used teenybin originally. I just downloaded it again now and flashed teenybin once more but got the same problem. I've tried lifeless and another stock based rom, but I still get the demigod crash. I used both TWRP and Philz touch to install stock roms. When I use an aosp rom and get into diag mode through the terminal I still can't use cdma ws or dfs to edit anything. I'm thinking stock might solve this, but that demigod error follows me everywhere. This problem is such a pain.
Viper Is here
http://forum.xda-developers.com/showthread.php?t=2486990
Alright I tried the lifeless stock rom and ended up with the demigod crash before booting up. I also received it when I tried the viper kernel. One more weird thing happened though. When I tried going into diag mode from the terminal on cm11 (4.4.4) windows didn't recognize it and I got the demigod crash. Could it maybe be that the dll for the lgnpst program is messed up so whenever I try to flash teenybin it corrupts the bootloader (I've done this too many times)? I'll try downloading and reinstalling lgnpst to see if it helps.
Alright, so I tried playing around with it a bit more and only got more problems. So after reinstalling lgnpst it seemed to make a difference, but still have similar problems. I ended up flashing a full bin of zvb after messing with teenybin for a bit, but it kept freezing followed by a reboot (tried factory resetting it too). Then I flashed the full zvc with more issues. It kept restarting again. So I flashed the unlocked teenybin and the power started acting weird, working sometimes (I've had this before when messing with it earlier). After I finally got it started from being connected to a charger for a while the phone got stuck on a new demigod error. This one said "Watchdog bark detected" and the screen was a weird yellow tint. Custom roms still work though for some reason. The last part is the meid and imea info shows up as unknown after flash the zero efs file with twrp. This phone is starting to get real annoying.
UPDATE: Alright, so after I flashed to zvb without success I figured there wasn't much hope on downgrading. However, I found there are some older ics bins. I downloaded the zv7 bin and flashed it. So far the phone has not crashed. I'm not quite sure why, but the jelly bean stock firmware causes my phone to crash. I will add more details if I can get it back working on Ringplus.
Some more details: So for some reason the zero out efs isn't working for me. All of the imei and esn info all shows as unknown on my phone. Stock hasn't crashed yet, but the spc seems to be corrupted or something. My old spc code and all 0's don't work. Cdma ws, cdmadevterm, and anything else I use to get into diag stuff always freezes when attempting the read for the phone. I hope my efs isn't corrupted beyond repair.
Any ideas? Short of replacing the logic board, I'm not really sure what to try. I've used 2 different computers to try and mess with the efs, but like I said the programs would hang. Could it maybe have anything to do with Windows 8.1, should I try with 7? I'm getting ready to give up on this phone, it's been bugging me for too long.
Alright, just thought I'd give an update since I finally got around to working on it one more time. I should mention that when I first had this problem I ordered another ls970 with a broken screen just to replace the logic board, well when I rooted it the same thing happened while it was being unlocked (or possibly before). So I figured I would just not root it or mess with the bootloader. Unfortunately that wasn't the problem. After ordering one last ls970 with a broken screen (they're pretty cheap at least), I replaced the logic board. It worked for a while, than the same problem problem occurred. I never tried rooting or unlocking it. I needed to update the profile through the settings, but that should not have done this. I can only think of 2 possibilities. My Google account managed to backup something from the other ones that caused the problem or something with updating the profile with Ringplus caused it. I'm just going to give up on it this time, working with esn fix didn't work and it would take way too long if it did.
Hi guys,
My f400l has been experiencing issues for a while now. One morning, I woke up to find an unresponsive device. Took out battery and turned it on again to find that the device had partially reset itself (ie. going back to stock launcher and layout, missing apps). Device was still rooted so I tried to restore apps and settings via titanium backup. However, phone kept freezing throughout restore process.
Next, I decided to flash back to stock. This is when i noticed that wifi would remain at 'wifi turning on' but never actually turn on. Additionally, bluetooth could not be turned on. I then upgraded to lollipop via normal firmware update from lg software on my pc. Phone then would freeze after every 2 mins.
After trialing many rooms, I am now on cloudyg3 2.1 but wifi/bluetooth are still not working and phone still freezes occasionally (usually at the beginning of the day).
Really at a loss here, can anyone suggest what seems to be happening and what I can do about it?
Thanks everyone!

Argh! So i tried flashing and upon reboot, phone came up with a security error. Currently reverting back to stock via download mode. I couldn't get back into recovery. Did I do something wrong? Thanks for the help so far tho!
EDIT: ahhh just realized i flashed a kitkat kernel, woops! Will see how things pan out for now
So i went back to stock and flashed a kernel but that didn't seem to help. Can't seem to find a zip file for kitkat baseband so I'm a bit lost as to how to flash a modem.
One thing I also noticed is that fact that i cannot access recovery via hardware buttons? I use power and volume down but the combo doesn't work. It just boots normally?
D851 here, When ever i switched from cloudy 2.5 to blisspop 4.0 and after wiping everything i flashed a various of radios bootstacks and etc to make it boot after many failed attempts to boot ( it boots up but after 4 or so seconds after the lg logo the screen turns black and doesnt turn back on until after i pull out the battery) it worked after i flashed the rom WITHOUT a custom kernel so naturally i booted up just fine and thought maybe now i set up everything on my phone and tweaks i should go back and flash a custom kernel i used to use (777 r16) but then it gave me the problem i faced before the black screen after the lg logo no kernal would work. THEN another problem arised similar to the freezing on the black screen randomly during a usage thru my day the phones screen would be unresponsive animations but touch wouldnt work and i know its not my screen cause when i flash back to cloudy it works fine the freezing happens at least every 5 mins. someone halp?
i know this thread is kinds old...
but i have this same issue too... I found if I switch batteries the problem isn't as bad... but, then it becomes bad again. Its weird. Before I swapped batteries I couldn't even login with my google account, after a fresh flash. then after I swapped batteries (gf has same phone) I was able to get through to the end and setup the phone. But, then an hour later it started happening again....
OP, did you find a solution?

i actaully did i think one of the problems was maybe flashing over the same kernel? see what happened was after i gave up flashing the kernel i just flashed without it and to my surprise the build actually came with the kernel pre-installed...shocker and so i had no need to flash over the kernel that i wants because the maker of g3 tmo blisspop already had it in his build and it boots up fine( DISCLAIMER: i cant say this about other roms because the only one i actually tested and wanted was blisspop)

Okay.
Well, when I was flashing I never flashed a kernel.
Ill be getting a brand new Anker Battery in the mail today. Ill report my findings.
I ended up going to a stock based rom and the issue never happened. So I stuck with it. Ill have to do some testing later and ill let you know how the battery works.
It's not the battery
I downgraded my T-Mo G3 since I couldn't root it with LP on it. Went back to 4.4.2., rooted it, TWRP'd it, and installed the latest CM12 Nightly, Gapps, SU, etc.
As long as the sim card was OUT the installation was great on wifi only, As soon as I put it in it shut off right after, or during boot up. Take the sim out and it works. And yes, the only way to get back into recovery was pulling the battery and doing the key press to recovery. Mystified.
If I find out anything, I'll post it here.
I'd say do a complete return to stock, upgrade via LG Mobile Support tool all the way to 20G, see how it works stock for a while. Then root ( http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197 using the first method) and see what happens.
I used to have the problem described in this thread (http://forum.xda-developers.com/lg-g3/help/wi-fi-bluetooth-fm-radio-d855-t3284582/) and it evolved to another problem so I've decided to create a new thread.
I've already factory reset my phone several times, had marshmallow, lollipop and kit kat (current version) and none of the versions seem to fix my problem.
My phone randomly has wifi and bluetooth and other times it just doesn't. When it has wifi, I can use the phone for a while and after that the phone will simply crash and start bootlooping or will boot and turn off right away or turn on and have no wifi(and IP adress unavailable on settings). When the phone has no wifi, I can use it as I want , it won't randomly crash or start bootlooping.
Trying to reboot the phone will, most of the times, result in a booloop which can only be solved by removing the battery(sometimes even that won't solve it, and I have to wait a bit before I can put the battery back again)
Is there any way I can find out what's causing the bootloop, like a log or something through adb?
Really hoping you can help since I'm running out of ideas. Thanks for your time.

problem is that most logs get cleared at boot, last kmsg might have some info but why not just do a cse flash of the kdz ?

I'm running stock 5.1.1 rooted. Whenever the battery dies on the tablet, it will go into a bootloop when I charge it and turn it back on (gets to Samsung logo with no start up music). So far, that only thing that seems to work is wiping data. Has anyone experienced something similar? Bad install maybe?
I've had the same thing happen to me last night. I tried everything and nothing worked. I had to restore a old back up i had with twrp and it started fine. Not sure what causes it though.
I've been having this problem for 6 months now. Let me try a custom rom.

Update the twrp tp latest version.I had the ame problem with old twrp but now all is fine with 3.0.2.0.
mine just started doing this. i can boot into recovery but the touch screen doesn't respond. i can also get into odin. I believe i was running Rooted Stock 5.1.1. Should i just reflash (i was thinking of going custom like LineAge) or do i need to reflash stock rom? I was also reading about just flashing the PIT and EFS. i know it's a 3 year old tablet at this point, but it's been good to me and i'd like to increase my odds of bringing it back to life
