Software Problems - G3 Q&A, Help & Troubleshooting

I'm from United Kingdom and I have a LG G3 D855 - made in Korea and basically what's happen to my phone is I restarted it and it ended up in a firmware mode and everytime I take battery out and put it back in it sends me to that firmware mode so I gave the phone to the shop to have a look and he says the whole software of the phone has been wiped off, I tried to flash it using your method if my phone gets messed up or something but everytime it would get stuck after 10% so I handed the phone to the shop and basically he put a software on and it says V10J-GLOBAL-SI. But before my phone went messed up it was something like V20I-EURR-XX, I've been searching for files so I could try and get my phone software back but I don't know how too, I heard of 'KDZ' but what is the difference between tot file and a kdz and will the Europe kdz get my phone software back to normal or any method that you know that will get in back,
please reply I've been proper stressed.

[Q] Phone keeps rebooting at LG logo without a charger

Hello everybody at the LG G3 part of XDA,
A friend of mine has an LG G3 and his phone broke. So he asked me to fix it. I myself am an Oneplus One user.
So the problem is really simple to explain. The phone doesn't work when there isn't a charger plugged in. When there is a charger plugged in everything is fine and the phone works normally.
So my friend tried to downgrade from lollipop to kitkat ( I don't know what he exactly did ). He doesn't have much knowledge about phones so ofcourse it went wrong.
Here is a video of what happens.

I already did a full reset with the LG flash tool and put the stock 4.4.2 Kitkat rom on it.
I have also checked the battery and it has a normal voltage of 3.8v. My friend also told me that he already swapped the battery in a store.
I do not know anything about a stock recovery of an LG G3, but I tried to acces it and I could get in to the hard reset screen but when opted Yes for everything it got stuck in that same "bootloop". When the phone is in the Hard reset menu then it wil stay ON without a charger. In all other cases it wil stay in a "bootloop"
I asked another friend of mine who has a lot of experience with phones. He said that it might have something to do with the a file that keeps the battery in check in the bootloader or the recovery, but he wasn't sure which one.
Update: When I am on the lockscreen and I disconnect the charger the phone stays on until I touch the screen than it shutsdown immediately
Try to flash lastest kdz of your g3 model

Replace your battery. This is what happened to my phone last september, I thought it was a software related issue, but when I tried to insert my friend's G3 battery, it just boot normally. I think this is a common problem of the phone/battery.
P.S. I tried running stock again, tried on CM, AOSP, etc. but can't make my phone to boot without being charged, until I replace my battery...

Died during firmware update

Hi,
My LG G3 died during the night when a firmware update started and the battery was low.
Now the phone isn't booting. It gets stuck at the LG logo.
I can put the phone into download mode but not much else. It it's recognized by any PC I've plugged it into.
The main issue here is that I need to recover some very important data that hasn't been backed up (ye I know stupid). I've searched and searched but all I get are some iffy maybes mostly regarding some Samsung phones so.
You can try a using a linux os on pc sometime it can still pick up ure drives
Thanks I'll try.
Unfortunately I don't use Linux or know anyone that does outside of work so it will take a while.
In the meantime if anyone else has suggestions I'm all ears!
Now r u rooted with twrp
The phone is 100% stock
Just flash stock kdz in a normal mode not cse flash but you have to select exact firmware you had ....so you dont loose any data...hope it helps

Click to expand...
Click to collapse
How would I even know what exact firmware I had?
The phone actually booted up when started into download mode and gave the 'firmware update' screen but just stuck at 0%
Ok...try to flash what firmaware version you had before software update....i think ota not installed properly...if it doesn't work try to flash latest firmware for your phone...means which version coming as ota for your phone....also remember for the first time it's should be take some time to start.if both not working you have to do a cse flash ?...but if you sacrifice your data....factory reset is a simple option....you don't have flash anything just search in forum how to hard reset and your problem solve,think so ?

Possible bootlop - detail below, tot file not correct

Need hep with my probably dead phone.
I got suddenly problem with my G4 model 818N, . Working perfectly for 3 months, on 6.0 Today because of travel had to change battery with new battery, working OK after battery change. Them suddenly during use just reboot.. Phone starts after that, show screen apps are upgrading and stuck on logo for some time. Get very hot and reboot again some cycle
I succeed to put it in download mode, LG UP see it but when i try to flash firmware, it say TOT type not correct. I just downloaded kdz file renamed it and added to LGUP. Is this correct way to add kdz? KDZ is correct for this phone.
Anyone idea how to check if phone is dead or can be recovered? I don't care about data on phone, just want to see if can bring it back to life. I can enter download mode, but can not enter reset scree? This is little strange ??
If u want to flash a kdz, first u select from LGUP the update option ,select kdz and after that u thick the refurbished option. Hope this works for you
Some pics of whats i`ve just said

[BootLoop], Imei, [HELP]

Hi guys, I have a problem with my LG G3, on the back it says D855, but imei shows LS990. I tried to restore to stock rom via both KDZ and TOT... Through the TOT it told me that D855 version doesn't match and cancelled. I read somewhere to put a different .dll file that the guy send, so I tried.. didn't work out either. So i tried KDZ, restored to D85520A, everything went well, but when the phone loaded it said ,,Wrong version of android" or smthing like that. The phone is bought in Czech Republic, found out a KDZ file "Czecho" D85510A, so I tried that and I'm stuck at bootloop again Can't get to download mode, factory reset doesn't seem to do anything and PC cannot see the phone, so what can I do? Thx for any advice ) PS: Phone has it's moods, sometimes it goes to download mode, but mostly not.
And I have to say that LGMobile Support Tool shows LS990 too.

Flashed Kitkat On LGUP need help

OK so my old G3 (lets call this one G31)has a broken digitizer, but I had another G3 (lets call it G32)and I just switched their motherboards after I flashed KK on LGUP while G32 was on MM. So the G32 was fully and wouldn't boot. Then I tried to wipe it through its stock recovery and now it always goes to the android with that thing through its chest. At the moment I didn't care so I put the G31 motherboard in the G32 shell and screen. Everything worked and still had my data. Then one day it fell and the motherboard snapped. So now I want to fix the G32 but it doesn't boot and anytime I try to flash anything it never goes past 6% on LGUP and says communication failure. It goes to download mode but doesn't boot. I believe I also flashed the wrong Kdz because the phone is LGD852 Rogers and I flashed a Bell Kdz. Any help would be appreciated.
