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?
(XDA wont allow me to post links to the error from LG Flash Tool because I have under 10 posts)
KDZ's for Canadian variants are here?

[Help] Unable to flash KDZ into soft bricked D855

Hello! I am having issues flashing KDZs into my soft bricked G3 via Flashtool 2014 and LGUP. When flashing using Flashtool 2014, an error "connection to server failed" is shown and did not flash the image into my G3. When using LGUP, it only recognize my G3 as "unknown" and does not allow me to select my phone as I need to "select a known model". Could anyone help with this issue? The firmware I am flashing is V21A_00 and only have access to download mode. Thanks in advance.
Solution to LGUP LG G3 unknown
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11.

Unlocking LG G4 F500L using Salt

I want to unlock my LG 500L(I guess everyone wants that right ) which is updated to nougat.
I tried to downgrading using the F500l20u kdz from lg firmware using LGUP but it failed at 11%.
Replaced the .dll file , still no luck.
Tried to go back to LP using the tot but it failed giving the unknown command error.
So if anyone of you who want to support the unlocking of LG g4 F500L with nougat can give me suggestions on how to go back to MM in order to flash the USU.
Flashing back the Nougat kdz works fine though.

LG K10 2017 Flashing the firmware to get rid of bloatware

Hello,
I am the owner of K10 2017 M250N, however LG Bridge say's that it is M250E. I have tried flashing the firmware with the use of few applications such as LG UP, LGFlashTools both versions 2014, 2016. and LG Bridge.
All those methods have failed I have even tried to change the kdz files while the LG Bridge was downloading the official firmware for my phone, however I DON'T WANT IT AS IT HAS A LOT OF BLOATWARE.. As the LG Bridge never had a problem with installing the firmware I couldn't replace the KDZ even when I changed it name to the official one.
My question is, is there a way to flash different KDZ from the same phone, region etc ??
All help is appricated,
Thank you.
