Help!

I have a F400K model, I was able to root and flash the 2 custom roms (Sphinx /VTD) fine, but when I tried to flash back to factory stock, my phone now shows it's a F400L model for some reason. So trying to flash the F400K tot file doesn't work (It works with F400L though). Is there anyway to get back to the original F400K model?

From your first screenshot, I think you have the same issue as me, the phone is recognized since it wont get to that error if your driver is not working. I was able to flash F400L tot file on my phone even though I have an F400K model. Just posted and hopefully someone can help and provide details on what I need to do in order to flash the original F400K factory firmware on my phone.

Yes same thing happened to me, it turns out that its not a driver issue my phone accepted the F400L TOT file although my device is F400K it is strange.

my phone is stuck at factory reset status 2. Everything went fine until the last part and it failed...
EDIT: I installed the latest flash-tool and re downloaded the dll and tot files and its still failing at the very end....

EDIT 2:

I have tried again, and still nothing. It will sometimes get to 99% and then fail, and other times it won't make it past 11-12%. I re installed the latest drivers, flash tool, and re-downloaded the dll and tot files. Does anyone know how to unbrick it? The most it will do is get to factory reset status 2, but then if I run it again after it fails it won't find my phone, and it only boots into download mode. It's a never ending loop of that or factory reset status 2 no matter what I try. I would really appreciate any help. I have a F400S and I downloaded all of the correct files from the other posts. My phone crashed after flashing a ROM and now well, here I am.

After factory reset stays 3 don't unplug the cable and it should reboot and startup that's the ending step.

Hi there! Thanks for you reply :) I waited long enough for a reboot and I decided to unplug the cable, remove the battery and thank my lucky stars it rebooted up well... I managed to update to the latest version .. Version F400k10g.. (Since I'm in Korea). I read somewhere on the LG G3 forum that you can only unplug after " Factory reset status 3 ".. But I read that after I took the "risk" :)

Hi there! Do you have the correct .dll and stock version for your phone? Try using a newer version of the flash tool.. I used version 1.8.6.527. Make sure you set COM ( Under "Device Manager" ) to COM 41. Good luck !!! :good:


No luck... :crying:

I'm still getting the "Model Information Check FAIL!" Notification.
The Model I'm using is labeled "Not for sale"

I updated the flash tool to verison 1.8.6.527 and checked the COM port to be 41

I'm actually not sure I have the correct .dll and tot-files. Is there a list for them?

Any suggestions :(

Make sure of your model number!!! Then post the model number and I'll check online for the correct .dll and tot files.


Go under " Settings, About Phone, Software Information ".. :)

If you can't get into your system .. check your phone package.. On the box, it should have your model number.
