AT&T LG D850 stuck on download mode (posting after almost all possible ways) - G3 Q&A, Help & Troubleshooting

Hello
I recently bought an LG G3 D850 32GB AT&T with version n, that is D85010n and while trying to get CM13 on it, i have got it stuck in download mode.
I have tried all possible solutions, searched on google, to get it recovered but I think its all about the firmware version conflict that the flashing fails.
1. The phone doesn't go into recovery or fastboot mode.
2. Trying to charge while turned off, results in entering download mode
The last resort i thought was the DLL and TOT flashing via flashtool but it failed too saying "Change Partition Error" [3 sec]. The firmware i used, and widely available is LGD850_V10D-xxx-xxx or LGD850_V10f-xxx-xxx. I dont seem to find the V10n version of the rom.
I am asking for help here please. Is there any way to revive the telephone? It was originally on kitkat 4.4.2, unlocked for other networks.
thanks

[Q] F460k OTA update error

LG G3 cat6 F460k model. hi guys. I just received a brand new F460k and i am not able to update it to lollipop. When i go into update center and then phone version update, after clicking on check now for update, it gives me an error "update service is limited. Please contact lg service center". I am currently downloading the lg pc suite. I have attached the software information. Also, I put up in India and I don't know whether that's the problem as my G3 is Korean variant.
Also lg pc suite, but it gives this error "cannot run upgrade. Check phone status and retry". Is something wrong with my device?
Can I flash F460k lollipop kdz manually using download mode
But if I do so
These are all LG Korean refurbished phones.. But they don't support it and not licensed to sell in korea. That's why e-commerce sites selling these phones with deep discount. But I wonder can I able to flash lollipop kdz file manually. If I do so will it affect SIM lock or SIM network read issue?
It's going to download mode when pressing volume up button while turning on and I downloaded lollipop kdz for f460k. Can I go-ahead and flash it. Or it will give boot up or hard brick. It isolleh . Thank you.
Flashed F460k v20c kdz lollipop everything fine and i rooted using one click root.Is there any custom rom available for lollipop as of now. Or i will downgrade to kitKat by flashing kdz and root and recovery andis there any lollipop custom rom available from stock kitkat. And by the way still automatic download not working same error when checking for new updates. Planning to go back to kitkat stock and install any custom lollipop rom available.. Olleh is having annoying bloatwares in korean language to get rid only i need to go custom rom.

LG G3 Fastboot Mode Started Error

Hello,
Not new to flashing roms but, was recently running CloudyG3 2.5 Rom on my lg g3 D852 and wanted to switch to the kitkat version G3 1.2 during the installation I accidentally clicked on another version other than D852. Now the phone is stuck at Fastboot Mode Started.
I am unable to get into the recovery but, can access download mode. Currently there is no .kdz file for my carrier but only a .tot file. Using the LG FlashTool and the given proper .tot and .dll I tried flashing my phone and recieve the following error.
"Device Model Different"
Can anyone help me?

[HELP] WARNING! Current version is not available for user.

Hello xda members!
Yesterday i just bricked my G3 D855. I wanted to flash the v21a kdz firmware on my device with LG Flash Tool but unfortunately i disconnected the USB cable from the phone while flashing. After when i tried to boot my phone i got this message at the LG logo: "Secure Booting Error! Cause: boot certification verify."
I searched on google and i found a program called BoardDiag 2.99a.
I followed the instructions in this thread http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 and after i got my phone boot into Download mode. I just flashed the v21a kdz firmware succesfully with LG Flash tool, but every time when i turn on my phone, after the PIN code it gives me a WARNING: http://i.imgur.com/FWASnak.jpg and i don't know how to fix it. And in the Phone information -> Software version is changed to v21a-GLOBAL-COM.
I searched for my problem on xda but i didn't find any helpful thread.
I hope someone can help me here.
Thanks in advance!
Hi
I had this on my D855 Taiwan version. I had installed the Euro version of D20h and got the exact same warning although the phone worked ok but it disappeared when I installed D21a which was for Taiwan region. I downloaded an app "LG Phone From" which gives information regarding which is the latest stock Rom for the phone. It appears that the warning is because the Stock rom is for the wrong region.

LGD855 Changed to LS990 after flashing wrong rom.and wont go back

Hello Everyone I have a problem with my LG G3 which I have bought it recently was working nice but it had KitKat so I wanted to upgrade to lollipop but didn't know that LG G3 had different variant.
I've downloaded a wrong flash (LS990 sprint) and flashed it. so I lost the network and I noticed that the imei has changed. and I don't have the original IMEI of the phone ( the sticker on the back of phone is for D855 16GB not for D855 32GB).so I think its not the original IMEI.
After bricking the phone I've opened it and noticed that it was D855 written on the motherboard.
when trying to flash the original D855 rom it doesn't work (flashed it using the crossDLL method and using the Hex Method By changing D855 to LS990 to make the flash tool think Its LS990) the flash pass on both methods but i'm stuck on LG logo.
send it to some repairing services here in my country but they didn't fix it they thought its sprint so they flashed PrimeGSM but still no network.
I think I should change the IMEI before flashing D855 or something.
please Help me I've looked all over the NET but find no solution to this problem.
If you need more informations ask me. Help me as soon as possible this is the only phone that I have.
Did you ever figure out how to fix this? I have a ls990 which was flashed with PrimeGSM and is now detected as a d855... I have been trying to get this working for the last two days with no luck

Hello
What is the problem that you are facing ?
Is it a network problem or what ?
Primegsm is ported from d855 so i think it will show D855 on any lg g3 that does'nt mean that your phone detected as d855.
Make sure your phone is ls990 or another variant
And which country and carrier ? So i can help you.
I basically have a soft bricked phone - no OS as all. I am in New Zealand running on the Vodafone network.
I was using PrimeGSM and it was working fine but decided to go back to the stock ZV8, when running through LG Flash Tool I noticed Download mode was showing the model as a D855 and would not accept the LS990 DLL - I then made the mistake of using the generic DLL with a D855 image which started a boot loop - then made more mistakes and ended up with no OS and stuck at the LG logo.
At this stage I am able to get to fastboot and use fastboot boot to get into TWRP but cannot do much from there, I also have to use the D855 TWRP image as the LS990 fails with a device tree issue. fastboot will not erase any partitions or flash any images manually. Using terminal in TWRP I am able to browse the partition though but cannot mount the SD card or use adb to push or pull (fails with error closed)
I stuffed up quite a few times along the way but sure I can recover from it since I still have quite a bit of access to the device...
I managed to get my phone going again by following a guide I found in the forum, I am pretty sure it would solve the ops issue as well.
Really quick and easy, I just bridged the points with a needle and copper cable.

have to leave my dedicated carrier forum to get answers for KDZ and or tot method

Multiple threads little to no replies besides sensless info that ive already tried
CAN TOT METHOD WORK ON TMOBILES VARIANT G4 AND IF SO WHERES THE LINK FOR THE TOT FILE NOT KDZ!
Tmobile g4 forum is helpless after days and 100s views
this is my last hope. I Have a tmobile lg g4 model. I hapened to relock the bootloader while i was still on a rom and rooted with twrp, but i do have download mode and only download mode .I dont have a bootable o.s
Ive tried and tried and tried to get lg UP Tool which is a joke its not really a true unbrick tool cause if you bricked yourself on a rom and not the stock firmware its useless .All you get is device model unknown. This is supposedly cause custom roms are edited. Lg bridge does not work as a brick tool either it just states wether your firmware is up to date . The only hope was lg flash tool 2014 but that im told and seems to be outdated not compatible with any g4 on android 6.0.... Im at a loss here i can get into dload mode thats it the phone charges in download mode also and it also is recognized by pc meaning drivers are installed because lg mobile support tool sees my device and says its up to date.
s
Some members have been in my same scenario relocked bootloader with a rom and twrp with nothing but download mode and swear they fixed it with lg bridge tool using the update recovery error link within the tool.
Can anyone confirm if im screwed or if i am doing something wrong this is day 5 now im ready to toss the g4 in the trash for the sake of my sanity.
