Help In finding firmware needed! (Secure Booting Error) - G3 Q&A, Help & Troubleshooting

Hello,
I`m in need for LG G3 D885 Kitkat Germany Vodafone firmware, the one hosted here (Germany Vodafone D85521A_00.kdz & Vodafone Germany D85510A_00.kdz) cannot be rooted and the other one doesn't work , the one that works seems to be patched by LG and I haven't been successful in rooting it. I have tried the one click method by avicohh thread both the GUI and the script, and the method by digital-bug thread . No other firmware works for me.. with everything else I end up with a bootloop. Unfortunately it seems that LG has stopped hosting firmware files on http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=355673068637086 and to my efforts and me following this guide I haven't been successful in downloading anything. If you happen to have the firmware I need I would be very grateful if you would share it.
Thanks in advance, and I look forward to hearing from you!
Edit: Look at my reply to the post for further info, I need firmware for the LG D85521A, and it needs to be Kitkat, unfortunately.
English is not my native language, so I apologize for any mistakes in my text .

I really really love this glorious phone (sarcasm)
So I found a firmware that I can root, thanks to hyelton. Turns out the Polish firmware hosted on his website can be flashed on my device and can be rooted. I was thrilled... but not for long.. :crying: I immediately tried to flash TWRP so I can finally flash CyanogenMod (my ultimate goal). So I downloaded Rashr - from the play store to flash the recovery, and apparently It did so successfully, so i clicked the button to go to recovery to finally flash CyanogenMod, and i got the Secure Boot error so I turned to Google for help, and help he did. I found this thread, and the end solution turned out to be to follow this thread . And here I am where I started . The solution is to flash Android Kitkat. I need the firmware for the LG D85521A model - this one only successfully flashes - so far.
So to anyone who knows where I can find the firmware that I am looking for I kindly ask of you to share it with me, and help me and others who are possibly going to face this problem in the future.
Thanks in advance, have a pleasant day

[Q] Help Needed for LG LTE LU6200

Hi All,
I got LG LTE LU6200 as gift from my aunt. But it is loaded with tons of Korean apps, which I don't need. I am also unable to uninstall them.
Currently my phone has Android Version 4.0.4 and Software Version LU620167.
I couldn't find any complete help for rooting and installing custom ROM in this phone. Can someone help me in this regard? (considering me as a newbie)
I will be very thankful for any help or response.

So your'e saying that none of the threads in the LU6200 forum tell you how to root and/or install custom ROMs? There's a few threads on the 1st page about rooting, unbricking, and installing CWM on the LU6200.

If it's in download mode, can you resume the guide from where you place it into download mode? Have you attempted to perform a factory reset (press and hold volume down and the power button until the factory reset screen comes on)
If none of that works, there looks to be a couple other guides there; best bet would be to try them. If all else fails and you need your phone to at the very least, work as a phone, you might can try to update your phone to stock using the LG update software.

Yes, I performed a hard reset, and after that, LG logo appears and then again I am back to download mode screen
Can you please give me a link for other guides as this forum is flooded with topics and I couldn't judge which procedure should I follow?
Once rooted, you can use Root Explorer to remove native Korean apps (AhnLab, LG counsellor, Tservice etc.)
Can anybody please tell me if this phone is USB-OTG (USB Host) enabled?

Try to search again in the LU6200 development area for your question, if you are not able to find the solution in there you will have to translate vietnamense and chinese LU6200 sites with google translator

LG730 - Venice - Downgrading firmware to ZV5 from ZV8 so i can root it

hey all, just got my 1st smartphone here. the LG Venice.
i love it , but always wanted to root it. that was the main point in getting it.
so i went and got this the other day, and unfortunately the guy at the store
went and upgraded it for me from the good version to this new UN-rootable version.
at the time i didn't know this, or i woulda stopped him.
soooo, I've been reading all over and the consensus is to downgrade it to zv5,
then root it, then save the root, then upgrade back to zv8, then restore the root.
ok, no prob, but i cant get the zv5 firmware to take. i;'ve found only 1 place that has a link to a .cab file. and it don't work.
others have had this same problem, but i cant get ahold of anyone....
if i flash 5 on it, it gets stuck at the boost logo screen. only way to fix is to flash 8 back on it.
so if anyone has an idea or a good zv5 image, or a link or something! or a way to root it as is.. please help!!!
thanx

[request] please add lg g3 beat or g3 s to device list

XDA moderators
Please add lg g3 beat or g3 s or g3 mini to device list.
Thanks in advance.
pls help me
I know that this is not the correct thread but since there is no LG3s threat yet I post it here.
I kind of brick my phone trying to update the preinstalled Google Apps (on /system).
Every time I start my phone I get an error corresponding with Google Play Service.
Could somebody with a rooted G3splease upload their /system Partition I will try to fix my phone this way.
I would just flash the official Firmware but I cannot find aly .tot or KDZ file for our G3s.

I had HTC device before it was easy to root or....but I'm new to LG and don't know how to root or unlock it. And it will take some time for me to learn these. I love helping you but I'm afraid to brick my phone and loose warranty and there isnt any stock rom available to go back.
But if you write the instruction on how to root and backup system partition and go back to stock rom I'd be glad to help.:good:
Edit: my device is D724.
Adding this device would be great!
LG G3s (D724) is already very popular in CIS.
And I want to find stock firmware to!
Maybe there's a way to backup it from my device?

Kdz
@mukesh_bhootra check the general session. There's a sticky thread about returning to stock. There you'll find a kdz filed for your e985. This thread is by Hyelton if I'm not wrong.

I fix my phone through flashing cyanogenmod and gapps. I wipe dalvik cache, cache, and system and start to flash it. Hope it help for you and im using lg g2 normally with it

Help save a bricked lg g3

:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!

Folks.
Got the same problem now (with my wife's phone). I'd appreciate it if instead of helping people privately you'd tell everyone what to do to fix the problem.
I had the same problem, downloaded .tot file via IMEI check (can't remember where from) and used that .tot file with BoardDiag, flashed everything as in tutorial (google it), it was 4.4.2 Android, couldn't update it (software is up to date) so I rooted it, flashed twrp 3.0.0 and installed Fulmics 8.0, it works now just fine
