[Q] Bricked Phone ?

Hi, i don't know what happened. I had CM 12 installed but then wanted to try Miui v6 so i downloaded it and flashed it but accidentally uninstalled gapps and WilKernel so the phone kept booting back to recovery without being able to flash any roms. So i followed this thread that told me to flash TWRP 2.6 and that it worked with any recovery ( I had 2.8 ) and now there's nothing that happens. I turn on my phone and and it stays on the LG logo. Can't get into download mode or anything and i'm scared to death right now since this is not my phone. Someone please help me !!

Are you sure you can't get into download mode? Have you tried pulling out the battery and wait for a while before trying again?

I actually unbricked it with LG flash tool, the only problem now is that it's stuck on JB..

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

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 ?

[Q] My G3 D855 shut down with no reason every few minutes

Yesterday I had a serious problem - my phone had a kernel crash and after a while of working on it I managed to flash through download mode. anyway, after managing to flash the stock 6.0 my phone won't enter to recovery mode, and every time I turn it on after a few minutes when the phone shut it's screen due to me not using it it won't turn on unless I would remove and put back the battery.. Any ideas what should I do? Thanks for every help!

I've Tried, tried through LGUP and it showed me unknown model so I couldn't do it with LGUP. Also tried with lg flash tool and had a disconnection with server and couldn't flash...
When I try to flash the 6.0 kdz it has the same message but after a while I press Retry and it flashes the 6.0 kdz.. after flashing the phone will turn on and work for a few minutes (not 100% ok) and then shut down again, with the ability to turn back on after removing and replacing the battery (and the all shut down process continues).

Thanks for everything, for now it works. I flashed all over again the marshmallow version and this time it didn't even turned off yet.

so after a day of using the phone is shutting down again and won't boot into recovery (since I have stock recovery) and won't boot into the android system - can only get into download mode. what should I do?

Maybe you have a battery problem, try another battery.
Verstuurd vanaf mijn LG-D855 met Tapatalk

that's what I've been through: kernel crash due to connecting the battery when the phone was connected to pc with usb cable. than after many times I tried flashing through download mode with lg flashtool it worked for almost half a day and then suddenly it crashed again (when I tried to install spotify on my phone). all through the process when I tried to flash a stock rom with LGUP it wasn't possible because of unknown model error. right now I re-flashed the marshmallow version (because for some reason that's the only stock rom which I can flash and it would work from time to time), and it crashes all the time after a few seconds of using it and getting back to boot loop. Mods I can enter: Only download mode (no recovery and crashes when try to turn it on)... Any ideas what my next move should be?

Root, TWRP install, reboot in recovery and paper holder phone!

Hi all,
since 3 days i faced some problems with my D855 stock lollipop (21A) ROM, I tried SUPER-SUME to escape kingroot,but it fails to install SUPER-SU and i lost my root access, GPLAY was very low speed in downloading and installing app; i was rooted (via Kingroot) and TWRP installed.
Yesterday evening i try to recover the situation via normal flash mode the original 21A rom.
It work so i root it again and install TWRP via AREC app.
This morning i try to reboot in recovery, the phone switch off and ..... nothing, it's dead, no way to boot it either in normal, or recovery or download mode.
Is there anything i can do before send it to service or it's unusefull?

You can try this, didn't work for me because I was stupid and short circuited something wrong. But send ir to warranty and they gave me a new one. So no problems.

Phone in service,but just for my info i read a procedure to unbrick the phone stucked on Qualcomm 9008 error..... how can i find if it is the 9008 one?

Yesterday my phone did that and I flashed the KDZ as if the phone was on, up+USB until I heard the sound on the pc, ran the flash tool and it worked.

Personally i don't really like flashify or any other similar apps.But as you are a beginner at all these follow this simple steps.
Can you boot your phone?
Try using the official App provided by TWRP
Go to Google Play Store and search Official TWRP app,download
Go to the application and select "TWRP Flash" option,after that select your device model and then select the latest TWRP version(3.0.2.0 or 3.0.3.0).
After all these click the bottom Download TWRP.
That's all.

I see that you have messed a lot with your system partitions.
I'll try to find something helpful.
Till then try checking if you can use system upgrade.(To go for example to lollipop while it may save your phone and also be able to flash the correct laf.img)
Question:After you finished the procedure on flashing the laf.img(for d851)(also you can flash the 10d laf.img as the OP said in the guide)did you pull the battery out and Boot to download mode(manually)?
How to get to Download Mode

yes i did try to boot into dl mode manually..

You also did pull the battery after flashing laf.img(10d) for D851 Model?
So... I think that after you tried doing all these and nothing worked, you'll be unable to get Download mode back,but let me check some of the system partitions and check if you can manually insert the laf.img file.

Somehow you can insert the laf file to your phone but it needs extracting (the laf.img) to get the proper file.
I found the location of the laf file.
But if anyone can be found with D851 can send the laf file here for you.
Two other solutions are:
1.Staying without dl mode? Maybe.
2.Buying a new motherboard.
