LG G3 Hard Bricked itself a day after un-hard bricking - G3 Q&A, Help & Troubleshooting

So yesterday i managed to unbrick my hard bricked LG G3. So i eagerly went and got a sim adapter today and started loading all my apps and stuff on. Long story short it got tonight and I was putting the last of my music on it and it stopped, I thought to myself that's odd and proceeded to try and turn the LG G3's screen on only to find it wouldn't respond. Restarted but it wouldn't get past the LG logo so i turned it off and tried recovery mode, wouldn't boot into that either. Last resort was download mode and that failed too. So two days after fixing the hard brick its hard bricked again :crying: anyone got any ideas as to why this would happen ?

[Q] Help with soft/hard bricked phone/

Hello,
I've bought a Hong Kong D855 from ebay when I was visiting US (I'm from Brazil) and for some months it worked flawlessly. SOme 2 months ago it started rebooting and I had to factory reset it. It happened twice a month and every time I had to factory reset, for it would boot normaly and reboot after a few seconds.
So I got to avoid updating apps and avoided installing new ones, because I couldn't find a definite solution on the web.
It was stable for a month but yesterday it happened again, but this time, after a few reboots into the OS, it froze in the LG logo screen.
And this time I can't even hard reset it - it just freezes on the same screen. I tried everything I found on the net - removing the battery, trying download mode (it goes directly to the same LG logo screen) and even just charging is weird (it shows an image of an empty battery with a frozen loading "animation").
I never rooted or did anything besides updating the firmware OTA. I'm on vacation on the beach, so I don't have with me the original charger (I'm using a samsung note 10.1 2014 one) and I don't know what else I could do.
As I've bought it overseas, LG won't cover it with a warranty, so have it officially repaired would be my last resort.
Does anyone have an idea what I could try? Or is it game over for me?
Thanks for any help, folks...

You might want to try and do a .KDZ Flash in order to take your device back to stock.

i have the same issue but it wont let me go into download mode either due to this problem
Bootloop/Error Code 1006
As of this morning, I am getting the exact same error - just started doing it while sitting on the wireless charger. Removed battery for half-hour, removed SD card - nothing helps. All I get is brief flashes of the LG splash screen, then nothing.
If battery removed and USB plugged in, I only get a battery/flashing question mark symbol on the display and phone does not power up.
Phone is maybe two months old, not rooted, so am very disappointed in my first LG phone since enjoying a few HTCs (Hero, Evo 4G).
Let's hope the Sprint store backs up their TEP with a brand new phone today...

I bought mine a week ago too :/
What month was your device manufactured? You can check on the outside sticker on the original box (if you still have it)
Mine was made in May and i'm having this problem. I think there was a bad batch made shortly before release that had defects. Here are some others with the same problem with phones made in May
lol just send em in on warranty.

yup. you're right. i'll be doing this soon
My problem this, please check solution please
my g4, 818P just had boot loop this morning. suddenly it was restarted and when I looked at it I really wish its not a boot loop, i did have a bad feeling and it became true. damn. I guess its the may batch *I cannot find the manufactured date but I pre ordered this, so this is maybe the first batch.
I took the battery out, SD card, sim card, no luck. Then, I let it boot loop for few times. I don't know maybe after tens restarts it show Android is starting and optimizing apps *and its still optimizing 56 of 116*. This is the second time, the first time when it was optimizing 17 apps *and I picked it up* the device suddenly restarted and stuck in boot loop again.
After read the reddit thread its the same symptom. I guess it really need to be replaced with *refurbished like new device* its just like a second-handed device after you had pre-ordered it.

[Q] G4 bricked itself stuck in bootloop factoryreset doesn't work

Hi all,
yesterday my phone ran out of battery. I plugged it in(original accessory) and started charging.
After some minutes it started it self( as usual I guess). However it got stuck on bootscreen( boot animation) and restarted.
I left it plugged in over night, but nothing changed. This morning I tried to do a factory reset via hardware buttons and it got stuck there as well.
It restarted itself and nothing changed.
Is there anybody who has an idea what to do?
Thanks in advance.
have a look at this thread :
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
I saw that, since I already returned the phone to LG it is obsolete now. Thanks anyway

LG G4 stuck in a different kind of boot loop.

So I have an, I beleive korean h815, I have been rooted for a couple weeks now, nothing else done to the phone. Today all of the sudden it stays on the LG splash screen. Very occasionally it'll start up and say "android is updating" but then it reboots the splash again. Is there a way I can just wipe everything and start like from factory again? I've tried the factory reset from the power+volume screen, I got to that screen, but it didn't do anything.
correction, it says twn on the box, so i'm guessing it's taiwan.
I found the thread on using LGUP to install kdz's. Went with the 20c kdz. Phone went to restart and it's just sitting on the screen that says LG. No animation or anything. Someone please help.
I had to buy am LG g stylo to get me by. I really want to fix my g4 and return this thing.

Can you tell us your android version? I think i have exactly the same issue which is quite annoying.
Each night i put my phone in the power plug with flight mode ON. In the morning, when i remove the flight mode , the phone restarts and falls into bootloop. Happened 3 times exactly the same way. I went for PCB replacement the previous week and i got a PCB starting with ser. No 601xxx. Today morning when i removed the flight mode i got a bootloop again. I am sure that this is caused by the V20D version that i installed the last days.... LG messed up again...i have a bootloop each week..
Not sure. But this is staying on this screen, it doesn't restart and stay on.

g8 (att) bootloop

Hey hey people. Been around this site for years since i had my htc mogul i believe. I searched for some help with the issue im having and came up empty. I have an lg g8 thinq and it took an update late sunday when i was asleep so i dont know when. It immediately was acting funky and by the end of day - up until this moment it has been boootlooping i even fac reset and it isnstill bootlooping-brought to att and their hands are tied talk to lg or assurion (boy they really are jelpful there.....) anyone out there experiencing this because its my primary phone qnd as i sit typing this im on my old s8 qctive that is beat to **** but pulled the sim from my g8 and stuck it in here. Anyway it will get past the lg logo and start bootlooping at the att circle/emblem-every time until the battery dies. Hopefully i didnt break amy rules again i havent been on in awhile but this really is beyond frustrating my whole life in that phone and idk last time i backed it up but its been awhile. THANK YOUA to ANYONE that can help point me in righht direction. Also i forgot to mention non rooted completely stock.
So you've already held power and volume down at the same time with the phone on?
I am too having the same problem. Mine is a T-Mobile LG G8, stock non rooted, got updated last week and then acted funny(some apps crashed), I restarted it won't reststart; Stucked on some LG-G8 screen. I hard reset it (Vol Down-Power/LG Screen, release and then hold power button; and then hard reset), After that: it stuck on boot loop.
What I can try next?

When my update came through on T-Mobile it got stuck at the Tmo splash screen. Pressed the power and volume down until it turned black and let go. It rebooted normally after.

Hi guys, am just a newbie here from Malaysia and a new owner of a 2nd hand LG G8 ThinQ (LM-G820UM); no idea where it's from but got it already with Android 10 update.
'twas working perfectly fine for a few days, but suddenyl got stuck in bootloop after I reboot (Power + Volume Down buttons) the phone when I was trying to change to a different SIM card. It would remain in bootloop until the battery is drained.
I can connect it to my laptop and seems to be detected pretty good and able to switch to Download Mode, but can't re-flash with either Flash Tool or LGUP.
- Have tried to use different Flash Tool versions - in version 2014, the flashing will just stop at server error, in 2016 and 2025 versions it will require LGST login (apparently to connect to some server which require registration).
- same goes true for LGUP, both versions 1.14 and 1.16 (patched version) will just stop at 4% then the apps will close without any error or anything happening in the phone.
Appreciate any help to recover this phone which I paid for a few hundred dollars as I was impressed with the spec and was so delighted to a very good spec phone; then this happened.
Thanks!

I'm in the same boat but with ATT. LM-G820UM I believe. Completely stock software. I just had it sitting on the charging dock for a while and I came back to it and it was stuck in a bootloop. No idea what's caused it, but I can't seem to get it to stop for anything. This is one of the many reasons I find not having a removable battery deeply upsetting :/
okay will try that as soon as i can get this thing to boot normal again it now stuck on the lg g8s screen think i flashed the wrong abl_a and abl_b files
Has there been any progress in getting this fixed?
Other than flashing the entire stock kdz not sure what else can be done...
