Hi,
I've a LG optimus G Korean version (F180L). I'm facing issues to update official firmware in my mobile. While I try updating firmware using LG mobile support tool , I get error 'Not enough free disk space'.It's a brand new mobile and have lot of free space. I searched the forum for resolving this issue, but I couldn't find suitable solution.

Then I tried updating the firmware using KDZ tool as per instructions in this thread:
http://xdaforums.com/showthread.php?t=1861854

I entered into software mode by power button and volume up key simultaneously and upon LG logo pressed volume down key twice and then connected the device. I got a message as in the attachment(software mode),I don't know korean hence assumed it to be software mode. Then upon flashing I got the message as in attachment(flash error).
Can someone help me flash an english firmware in my mobile.

TIA

The screen says:
This is a state for service center's backup and upgrade.
Usual users, please dont use this state and leave it by holding the power button for 8 seconds.
Something like that.

Your logs says:
Port= -1
and PHONE NOT FOUND.

I bet you didnt install the drivers properly or you didnt choose the proper port

Thanks mate . My win 7 laptop didn't like the phone . Tried with xp laptop and LG support tool worked like a charm.
Still I've Korean firmware only. Is it possible to flash an English firmware in this phone ? If yes , plz give me the firmware DL links if anyone have got. The DL links in firmware thread have been removed .

Contemplating trying to flash .kdz to downgrade firmware and regain root. Battery life seemed better when rooted, with 50+processes frozen (Titanium) and cpu profiles set (setCPU).

Before flashing the .kdz, which PC Connection mode do you select for the device (charge only/ mtp/ lg software)?

I didn't flash it using kdz tool, just updated firmware using LG mobile support tool and I used LG software mode for that.

I tried downgrading firmware via flashing .kdz but keep getting the PORT -1 error, not sure what I'm doing wrong...

- PC running Vista
- downloaded and installed LG USB driver using LG Mobile Support Tool, message indicates successful
- turn off device, reboot into service mode (hold power + vol up)
- connect device to PC via USB
- Device Manager, no LG modem listed **I think my problem lies here somewhere?**
- run Windows Enabler as admin, click in tray so "ON" is displayed
- run KDZ_FW_UPD_EN as admin, Type = 3GQCT
- navigate to appropriate .kdz file, press "launch software update"
- unpacks .kdz, then PORT -1, DEVICE NOT FOUND error occurs

any advice or insight would be appreciated. and Happy Holidays to everyone as well!

EDIT:solved. need to put device into Download Mode. power off. insert usb. hold power/ vol up/ vol down. release buttons when Download Mode icon apperars on screen. proceed. Cheers to boakun and l0ng0ne on the ICR channel.

Yes, I have a Korean device, since I live in South Korea. The firmware is Korean, with language set to English. When you set the language, literally everything is translated. I downloaded the firmware from LG servers using my own IMEI prior to upgrading to the latest ota that broke root for me.

Here is the method that I have successfully used several times.
- put device into Download Mode. power off. insert usb. hold power/ vol up/ vol down.
release buttons when Download Mode icon apperars on screen. proceed.
- Device Manager >> modems >> disable LG modem
- run Windows Enabler as admin, click in tray so "ON" is displayed
- run KDZ_FW_UPD_EN as admin, Type = 3GQCT
- navigate to appropriate .kdz file, press "launch software update"
- unpacks .kdz, writes to device. Be patient.

    It has been already discussed several times. Yes, you can flash, no danger in bricking, but you may end-up with non working wi-fi, no lte connection,even no network connection.
    If you would read more carefully, you'd see there are differences on modem,regarding LTE frequencies.So, before doing that, start documenting. In some cases it was a succes, in other cases they had problems i mentioned above. You decide if it's worth the trouble or not.
    PS : a simple search would enlighten you.

    Hi guys , my LG optimus G is a F180L , it has the same characteristics of the italian model (e975) . Can I change firmware with kdz or is it Dangerous?

    Hi mateI have sucess. done converting ..
    i can tell u how to do it when i get time .. swnd me PM will get back to u ..
    thing is about wifi ; your wifi WILL work but u need follow proces exactly LTE network will NEVER work cos in F180L devices is only one band frequency implemented JUST for Korea country where that band is used ..
    In EU they using different bands ..
    So we HAVE TO wait untill future smartphones WILL have all supported and used Lte / 4G frequencies implemented same this was with 3G in past..
