Can you please share (or you can just edit your post):

1. Your LG G3 model/variant

2. Kitkat Firmware version you extracted from

3. Your Lollipop version currently running

4. Did Download Mode work for you?

Hi [MENTION=6132698]ozaq1[/MENTION],

Actually I uploaded a video which you can download. The video download link, as well as the step-by-step, is in Post #153. That should help you. :)

I understand why you want to be as exact as possible on the firmware version to download, due to the multitude of models/variants of the LG G3. That's fine and actually it's good that you're doing your homework (I have done the same thing before I took the plunge).

Basically:

1. Download the "latest" Kitkat firmware for your LG G3 variant. This is where you'll extract the Kitkat Images.

2. Download the "latest" Lollipop firmware for your LG G3 even if you don't plan to use it.

Though the LG G3 D855 is the "International" model, I understand that there are many "variants" of it. The best practice that I would suggest is to look up the full model/variant name in the box and use that information when Googling for the firmware. Also, there are websites where you enter your IMEI (serial number) of your LG G3 and it will show you which firmware to download. This will be more exact.

Tip:

Kitkat firmwares have the number "10" on it. Lollipop firmwares have the number "20" on it. The letter after that means: higher letter = newer version.

Example: "10A/B/C/D" = that's a Kitkat firmware. "20A/B/C/D/E/F/G/H/I" = that's a Lollipop Firmwarre. In the case of a Kitkat firmware, "D" is "higher" than "C" so that means "D" is the "latest". Same logic for a Lolllipop Firmware. It's also possible that different LG G3 variants don't have the same "highest" letter available. For example, the "latest Lollipop" for my D858HK (dual-SIM variant) is "D". For the D855, depending on your specific model/variant, the latest Lolliopop is either "H" or "I".

Hi [MENTION=6529004]eldragon0[/MENTION],

I walked him through the "No Downgrade" method. Again, the "Imageprep" script is nothing but an automated version of the "No Downgrade" approach.

All three approaches (Kitkat Downgrade, No Downgrade, and Imageprep - automated No Downgrade) assumes that you are on a stock/official ROM. So if you are currently running custom ROMs, please reflash your device.

It's okay to update your device via OTA to the latest Lollipop. I did the same thing since at that time, there was no full firmware (KDZ) available yet. I used Imageprep.

The important thing here is, if you want to use Imageprep, you have a downloaded copy of the latest Kitkat full firmware (KDZ) where you can extract those needed image files.

Hi [MENTION=2872179]deankk[/MENTION],

Imageprep method, right? You will extract the image files from a

KITKAT

firmware (KDZ). And yes,

KITKAT

even if your LG G3 is currently running on Lollipop.
