[HELP] Can't flash KDZ files after FreeGee EFS restore

Please help. I can't flash kdz files anymore after trying FreeGee to install a custom recovery on my LG G2 D802.
I'm running stock 4.4.2 KitKat (SFR France 16GB D80220A_00) rooted with iOroot.

I also can't get it to Factory reset. When trying to install CWM through FreeGee it removed my Stock Recovery. Can't get to recovery, Can't force factory reset. When trying to factory reset through settings it does nothing and Terminal Emulator simply doesn't work, can't even write on it.
Is there any other way of flashing the KDZ file?
Need help.
Can someone point me to any directions?

[Q] Help! Flashing .kdz stopped working after TWRP

So, I've been using the .kdz method successfully to flash my D802 several times before, no issues at all.
I'm on stock 4.2.2, rooted and I installed TWRP, everything is working fine, but I decided to move on to 4.4.2 (stock) using the .kdz flash method and I just can't get it to work anymore... I've tried several times but I just get stuck on 49% all the time...
The flash tool says this:
13:35:04 : #################################################
13:35:04 : Indirect Internal / PC to Phone send end
13:35:24 : wParam : 13, lParam = 46

13:36:11 : ¿©±â´Â Retry ºÎºÐÀÔ´Ï´Ù
Any ideas?
I think I have really messed things up now...
I downloaded Cloudyfa's 2.4 ROM and stock KK kernel and installed using TWRP. Phone was working fine, then I used the .kdz method to try and flash again (stock KK ROM) and this time the flash completed fine. Phone started up but had loads of process stopping, so I did a factory reset and now all I get is the little android with the cube spinning. I can flash any .kdz again but as soon as the phone reboots, the android is there with the cube spinning...
Have I bricked it irreversably?
Never mind, got this working again now.... Flashed a JB .kdz and then up to KK .kdz and its all good

LG G2 D803 KDZ Fail 1% Telus/Koodo

Hello Everyone,
I have a Telus/Koodo D803 currently running CM12.1 and I'd like to revert to stock to test some signal issues. The problem is, the LG Flash tool fails at 1% or 2%. I'm using a Telus KDZ so it should match.
There are the last 6 lines of the log file.
00:32:18 : Step : TYPE_WPARAM_UPGRADE_ERROR
00:32:18 : CleanModelDll() : Free Model.dll
00:32:18 : _DetachDLL Call

00:32:25 : Page_Error ºÎºÐÀÔ´Ï´Ù
00:32:25 : ¿©±â´Â Retry ºÎºÐÀÔ´Ï´Ù
Any suggestions for getting this to flash? Alternatively, are there any threads for restoring the D803 specifically from a brick? That may also be helpful...
Thanks!

l7 bricked in a bit of a tricky way.

So i have an l7 bricked. It seems to boot to recovery mode only, but since it does at least that much it should be easy to fix right? Well no, after using every kdz flasher ever possible it still shows this:
Code:
03:45:38 : Launching SW update
03:45:38 : Unpacking KDZ
03:45:40 : KDZ file extraced
03:45:41 : Files were extracted.
03:45:41 : LGMobileDL Load.
03:45:41 : Port = -1
03:45:41 : Connecting to phone
03:45:41 : PHONE WAS NOT FOUND!
03:45:43 : ===FINISHED===
I installed every driver possible yet in device manager it doesn't show up at all. How the hell am i supposed to make it detect my phone?
Running win7 64 bit.

Try booting it in emergency mode ( and you have to set phonemode to emergency not diag) like this
take out battery
hold volume up button
plug in
yellow screen will come up (it is now in emergency mode)
I had my phone stuck in recovery, and the only way to connect i in any way to kdz was emergency mode, hope it helps
