check your hosts file and make sure everything is ok there. seems like the software is connecting to lg servers instead of your local server.

First of all what kdz are you flashing?? There's no D850 kdz file.
Your getting an error with flash tool is because your supposed to use the dll file that says use this if you have trouble. Or you have to use an hex editor to change the tot file your needing to flash. Just google hex tot file edit

Just like me.. you've been scammed. someone sold you 855 with a different board. 850 most probably. so try 850 tot files. not kdz. Cheerz

AT&T Lg G3 soft brick unable to flash error "Model Information Check FAIL"

AT&T Lg G3 soft brick unable to flash error "Model Information Check FAIL"
Hi,
I have an LG G3 D850 with stock rooted lollipop rom and I edited the build.prop changing the ATT to OPEN. I installed TWRP and while flashing cynogenmod it failed and then it wont go past the boot screen. After that I tried unbricking but the LG root tool says "Model Information Check FAIL".
Can anyone help me with this?
I always changed mine to open never had any probs are u sure u downloaded the rite tot and didnt flash wrong rom
Yes I did. Its just that the model number does'nt show up. Also I am using the KITKAT rom, should I use the Lollipop rom with the same dll file. I used this guide and downloaded the files from here.
http://forum.xda-developers.com/showthread.php?t=2785089
Ok so I figured it out. Apparently for my phone I have to use the dll mention in the link reddit.com/r/LGG3/comments/3ov9x6/need_help_lg_flashtool_model_information_check/

Going from T-Mobile D801 > AT&T D800

Hello all.
How do I go about going from a stock tmobile D801 firmware to AT&T D800 firmware? I tried using the LGFlashTool and it keeps giving me either a CrossDL D801 to D800 error. This is when I use the LGUP_8974.dll file and a LGD800AT-01-V10d-310-410-AUG-14-2013+0.tot. If use use the specific DLL for the D801, I then get a BIN Model is Different" error.
Thanks
