[Completed] LG G2 Stuck on Firmware update loop - XDA Assist

Hi i currently own a LG G2 in the uk from the network EE. I rooted my device a few months ago because i wanted to remove a few pre-installed apps. A few days ago i attempted to upgrade from Kit Kat to Lollipop using the LG PC suite via usb, the attempt returned an error and my phone is stuck on Firmware update screen, even after i restart. i can't seem to get into download mode either using the vol up + plug in usb method. I used the LG FlashTool to extract a KDZ file and it keeps returning the error "extract File Error", the current available list of websites i can find to download a KDZ file to download seem to return the message "file not found" or Access denied. My question is what can i do to recover my my phone and is there anything i haven't tried.

I would like to inform XDA-Dev that the LG Eclypse | LG-C800G Stock Rom in KDZ file format is the true stock rom for the LG Eclypse | LG-C800G. I have tested it and it recovered my device.
I will give a lil info on how I did it the best I can but bare with me as I was not really keeping track on what I was doing when i did it.
1.) Download the LG Eclypse LG-C800G Stock Rom in KDZ file format by going
here:
- http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=INSERT IMEI HERE
and enter your IMEI where you see INSERT IMEI HERE in the address bar
or if your with (Virgin Mobile CANADA) then here:
- http://csmg.lgmobile.com:9002/swdata/WEBSW/LGC800G/AVMBDG/V10c_00/V10C_00.kdz
2.) Plugged in the phone
3.) I disabled the lge android platform usb modem
4.) I clicked on msxml.msi and
uninstalled it. then reinstalled after
uninstall was completed
5.) right clicked on KDZ_FW_UPD.exe ( You can download KDZ_FW_UPD.exe here: http://forum.xda-developers.com/attachment.php?attachmentid=420545&d=1287222698 ) and
went to Properties then Compatibility and selected Windows XP SP2.
I also clicked on Run this program as an administrator. then pressed Apply or OK
6.) I then opened up B2CAppSetup.exe (DON'T DO ANYTHING WITH IT YET wait till you get to ((STEP 10)) ) it can be found here: http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
7.) I then ran KDZ_FW_UPD.exe and only changed the phone mode to EMERGENCY or CS_EMERGENCY I can't remember what one i picked so try all.
8.) I then selected the KDZ File
9.) I then pressed Launch software update as it was extracting the KDZ file
I did this (Step 10)
10.) I then went back to B2CAppSetup.exe then clicked on Customer Support then clicked on Recovery Phone then I entered in my IMEI then pressed Check
and there ya go. the B2CAppSetup.exe should look for and download your rom as KDZ_FW_UPD.exe starts recovering your phone. now let both complete even if one says its done.
Again hope this helps and sorry if its not a good guide as i was not keeping track as to what I was doing.
Lnks not working for the downloads
Plz am currently in gh same situation bt th lknks are not working. plz help me find th stock fom since I've looked allover in vain.
Halp
I need this, I have the T-mobile version of the rom. But I would really like the Canadian version, without the T-mobile **** on it.

[Q] how do i get my phone back in it's original state?

hi,
recently i have rooted my phone to get the most out of it.
a couple of weeks ago i got this notification message that an update was available for my phone's software, so i downloaded it via OTA.
when it restarted to install the update it came into CMW recovery mode. there is an option in CMW to install the update, but when i trie to install it, i get an error mesage that sais: no such file or directory. so i tried to update it manually and to get out of CMW recovery, but nothing helps. i also tried to get it back in it's original state, but apparently no one with this phone model has ever asked it on the internet, so i can't find a solution.
can anyone on this forum please tell me how i get my phone back in it's original state? if i lose my root acces, that doesn't matter. i just want my phone back.
my phone model is:
LG Optimus L3 (e400)
please help me, i have tried other forums, but no one gave a response there.
greetzz..

Where I can Find TOT and Dll file for LG H900

My LG v10 stuck on LG Logo, but when I attach an USB cable with computer it further goes to att logo and after 3 or 4 spins, it again stuck on att logo. I can get into download mod but not recovery or safe mod. I tried to flash my phone with LGUP but it shoes unknown model. tried with upper cut and common folder options but no luck. LG flash toll 2014 does not detect my phone and application stop responding when I try to read phone information. tried on different computers, different USB cables and different windows but the result is same. Once I had a LG f350 and faced the same problem. Only LG Flash tool 1.8 worked for my LG F350. I am hope full it may work for my LG H900 but I can't find TOT+dll file for LG H900 nowhere. Any one can help please.
I was on 5.1.1. rooted, Super SU and busy box installed when I tried to factory reset my phone and got into this trouble.
More Problems
I got a LG Firmware Extractor from a post on XDA. Extracted the KDZ file and got a .dz and .dll file. extractor also showing another file (something like .dllyib i think) but I ignored that and extracted what I needed. After that I flashed my phone with lg flash tool 1.8.. but flash tool kept on installing system file after 100% but my phone was stuck on 99%. After 117 % flash tool showed "waiting for connection" and then failed. I tried to reflash and got the same result. Now after showing LG screen, my phone got stuck on a black screen showing some bars going up and text "MiniOS" and stuck on this screen. I searched for the solution and some one told me to disconnect phone when flashing reached at 99% and then reattach it after changing the port. I did that but what I got was worse than before. :crying: Now I can get into recovery screen but after applying factory reset, phone goes off and restart again without doing any thing. My phone is stuck on boot loop at LG Logo. it keep booting when i connect to a charger or my computer . I cant get into download mod now. when I try to get into download mod, the screen with some dots appear and then phone restart again without going into download mod. when I connect my phone to PC it only do boot looping and nothing appear on my computer. My phone does not appear in device manager. Is there anything I can do now????????

Failed several times and gave up with LG UP. So i took my phone to a mobile service center who is good at software flashing. i gave him nougat kdz F600S30D. He converted kdz to dz format and flashed with Octoplus box. my mobile was on 5.1.1 android and directly flashed Nougat. Booted flawlessly and no network problems as well Everything is working just awesome. attached my video of Nougat Overview
