softbricked lg g3 d850 - G3 Q&A, Help & Troubleshooting

Hey!
I guess i just softbricked my phone, by installing a D855 firmware thing, using LGUP, and don't know how to fix this. To be correct, it turns on to the LG logo, and stays there forever. I can use hard reset, and it does the job, but still bootloop thing. I can also get into download mode, but nowhere further than the LG logo screen if i just turn it on or something. Tried to use LG Flash Tool on multiple computers one after another. I followed guides for help with it, and did everything as they described, but the problem with this, is after i use LG Flash Tool with the correct .TOT file, and .DLL file, it will just say "Model Information Chech FAIL.", so i can't fix it by flashing the correct files. I've been trying everything for 2 days, but no luck. Please, can you guys help me? :'( I'm worried.
Update: My phone is now fixed. I don't know how it got fixed. My brother did it, and he doesn't tell me how he did it. :'D Anyways. It's now fixed, so thank you for everyone who messaged me about this with helps. ^^ After 2 days of trying, its finally fixed.

Help! Bricked! "secure boot error" [d855]

I was trying to flash newest v10L on my D855 variant, i think it was the usb line problem, the flash was very slow and couldn't finish the process.
I know how fatal if i failed the KDZ process, but i had no choice but to reflash again.
and then my phone failed me, i can't get into downloading mode anymore, and the phone kept giving me
"[460] secure boot error", T.T, and the LED is flashing in a Red and Blue and Red pattern.
what can i do now? so frustrated at the moment.....
plz help me guys!
thanks so much!
I think your hard bricked now - sorry
were you able to get this resolved? I have the same problem. any info will be good.
pull the battery, and boot into either recovery or download mode, from either of those you can recover the device.
Secure boot error I believe is when you have a messed up bootloader. On an old lg phone we had to loki the aboot.img and by bypassing the bootloader those words would flash on the screen. Maybe try to reflash the kdz or a previous kdz. If not try to flash the boot.img and laf.img for your device via fastboot/adb. Lg makes a damn near unbrickable phone.
mate, i replaced my MB at LG customer service

sorry for the late response mate. I can't fix it at all by myself. so i took it to local LG customer service seeking for help.
after hearing and considering this and that options, i decide to replace my MB. It took 3 weeks for them to fix my phone.
they had to order the part from korea since mine is HK version and they don't have stock in mainland china.
now the phone is super sweet somehow, but i don't use it any more since i got myself a NOTE4.
my wife will give it to her brother. =)

G3 stucks in Download Mode

Hello Community,
Yesterday my G3 stucked in a Bootloop without changing anything. Than I wanted to repair it with the LG PC Suite. This failed with the message "Assert" multiple times. Now it stucks in the download mode. Can I repair it? More important are the files on the G3. Is there a way to get them?

Try this:
1) Remove battery
2) Hold down the power button for 30 seconds with the battery out
3) re-insert battery
4) Try turning it on again.
If that doesn't work, do a hard reset. You can find multiple posts on how to do it. Hope this helped!
Maybe I can help somebody with the same problem. I solved the problem with the following steps:
I setted up a new Windows 7 x64 PC. It must be Windows 7!!! No Windows 8 or other shiny things.
Installed the driver
Flashed a compleltely new firmware (.tot) over the old (!) FlashTool.
Hi guys. First, sorry my poor english. I'm Brazilian.
I make a firmware upgrade from LG PC Suite, 4.4 KK to 5.0 L. Problem is, the upgrade failed, and now my LG G3 are stuck in download mode. I try make this upgrade from LG Flash Tool but the problem persists, 65% appears in the screen of LG G3 a message "ASSERT" and reboot to download mode screen. Help, please?

Although I have never come across this, using this site to download the right KDZ and using this thread to flash that KDZ may solve your problems. There is no harm done in trying this and you can be sure that it is the right file.
LG G3 Boot problems after download mode
Hello!
Sorry revive the topic but it was the only one who found a similar problem, after searching lot on google.
I have a LG G3 D855P. Yesterday he went out and restarted many times, but worked for a short time.
I can use the BoardDiag, but when I restore the D855P20C_00.kdz .kdz, to reach 36%, the cell phone goes off and does not return. I need to take the battery cable, so that it returns to the download screen, but still, to get 36% he goes again. Have made sure that the .kdz file works properly.
I followed the tutorial presented in this video.

I hope somebody can help me.

I have a LG G3 D855 with the marshmallow KDZ flashed with flash tool everything was good and had no problems. Two weeks ago i rooted my phone and the next day i wanted to install Xposed and after searching for a bit i installed it and got stuck in the bootloop. I managed to recover it by using the .tot method and since then my phone is messed up, like when im using it it restart for no reason at all, or just when it restarts i unlock it and 6/10 times it restarts again. I don't know what's wrong with it and i was hoping someone knows what to do since this is very anoying Thank you
On i've asked for help on Reddit, but maybe someone here knows a solution for it. I really don't know what to do anymore.
Hello,
do you want to backup your app data? Easiest way is flash KDZ via flash tool with CSE flash (format all).

LG G4 Stuck In Firmware Update - Stock Reset?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%
Have you made sure that it is the right region......
Try to down load just tot file and try that....

LG G4 stuck on Firmware Update (KDZ, TOT - Not working)

So, some time ago I finally gave up on LG providing official nougat update for LG G4 so I decided to flash it and I found an official flash v29a, and everything went well.. except for my GPS. The GPS was not locking on and would take more than 100 seconds sometimes to lock on, I did not had this issue before so I decided to flash my device again hoping it would fix it, but it bricked my phone.
Now I can't reinstall or downgrade, since it would get stuck at 16% when flashing again and downgrade wont work at all. I get error 0x2000 "Invalid command Response". I have been trying to fix it for more than 6 hours now, downloading different KDZ's but it just won't work. I really need help here, I cannot afford a new phone right now. I have LG H818p version. And yes, I was using the correct version for upgrade/downgrade. I tried to hard reset it but it is still stuck on Firmware update. Urgent help is needed, since I don't have another phone to use and I really need this phone, been up all night trying to fix it..
Edit: Fixed it, don't know how tho
