still no advise?

still cant update

My first advise would be to get a dictionnary. My second advise would be to LGNPST back to stock rom then do the OTA.

Like Chad said, maybe flash back to stock. Here's a link to find the KDZ for your phone: http://lg-phone-firmware.com/index.php?mod=Lg+Optimus+G&paese=Tutti&id_mod=20

well so now.. im confused. can i have a third opinion?
also is this guide accurate in flashing the kdz for lgog?

please help me i used the kdz updater software, and it crashed at unpacking kdz. now my phone is in download mode, and no matter what i do i cant exit it

Flashing with kdz updater will erase everything.
Using Lg mobile tool, it will not.However, to be safe, copy sensitive data on pc and backup your apps with Titanium or any other app.After backup, copy the backup folder on pc too.
Only after you've done this, proceed to next step and flash stock rom. @nuker, why the hell would you a software designed for another phone'??
There is already a tutorial here,sheesh.I guess you deserve it, like everybody rushing into things without reading before.

lg optimus radio not working..helpp
guys i need ur help..
here s wat i did and messed up
i m a beginner in this andriod field so need guidence
i own an lg optimus G e970 at & t version on ics
i rooted it.... installed slick JB on it http://forum.xda-developers.com/showthread.php?t=2084431
but forgot to install the modem via recovery.... so when i turned my fone ON, i had carrier network signals available but wifi was not working....
so i didnt know anyway to make it work as i wanted to install terminal emulator and go into recovery from there (since my fone wouldnt goto recovery by power and volume down key.... only thing i knew was to flash an lg fone with a kdz file via marvin tool (R n D tool)
so i downloaded a KOREAN kdz for f180L and tried flashing it on my e970 via R n D tool...it was successfull but when my fone rebooted, it was country locked (required some password at the beggining)
so then i started looking for the other kdz,s available online (as i was specifically looking for kdz for at & t LGOG) but found that it uses tot file for flashing via LGNPST ( so i ignored it by thinking that i would go for kdz but couldnt find it)
(BY THIS TIME I HAD NO IDEA THAT MY RADIO IS DEAD)
then i found a brazilian kdz for e977 and flashed it to my fone via R n D tool and my fone booted up.....everything working but no network signal showing a sim error icon in status bar....i rooted it and installed at & t rom via zip via cwm n got n at & t rom but radio still not working
i tried installing e970 modem.zip and tried flashing tot via LGNPST but it doesnt work for me as LGNPST always give me errors.
when i backtracked everything, i found my mistake: people said that if u would flash a korean rom on a non-korean fone, u would loose ur radio.... thats the stupidity i did and now i n dammmnnnn frustated about it.....
even read about some efs file but no use...
pleaseeeeeeee helllppppp

You can't use lg mobile tool when you are on custom rom. The phone will be detected,but when you will choose to flash stock it will give you an error.
The only way is kdz updater.

If that .kdz file is bigger than 1gb, kdz updater will not work. Simply as that.
After searching around,i found there is a way to bypass official LG mobile support tool checks.
It's a litle more complicated,as you need to install small server and you have to edit hosts file in windows, but it will do the trick. You need to do this in order to make the app thinking it's downloading the rom from lg server.
here is the tutorial
http://forum.xda-developers.com/showthread.php?t=2085344
It's for the L9,but i think it will work F180 too....

it's not working. Even if it's file downloaded earlier with LG Mobile Support tool - it crashes during file extraction. Tried this with previous version of LG MST (this from thread You mentioned). Don't know why - tried only with one *.kdz.
BartxGamer - You can try this, but LG Mobile Support tool will update to new version, and it's hard to say - will it work?

You're wrong. I always go back to stock rom with this. If Phone is recognized with newest firmware, then You have to choose from options "Emergency firmware" and find ROM using IMEI.

there is an "IF" there.You got lucky, not working for everyone .What do you do if the phone is not recognized?

OR we will wait till official android 4.3 for F180k will be released. Than we should be able to update, i guess.
Yep, IF phone is recognized. But what if not? I tried it twice. And it stopped after checkint battery stats. You could only restart update or exit. And it writes, phone is nit connected.

Absolutely not, but you will remain as f180 and have to delete the asserets line everytime you flash or update a rom, mod, recovery

Hmm... I never had to do that. Like i said, I rooted and unlocked straight from F180, then flashed multiple e975 ROMs multiple times via CWM with no problems whatsoever. The device is always identified as E975. Didn't have to do anything extra. Just sharing my experience...

Hmm I'll try again confirm later, done same in early days of my device and it was f180 so i had to remove assert line every time.

Tutorial needed for flashing stock eur rom
Hi there,
I have the Korean version of the Optimus G (F180s20n) and read about converting it to a european stock rom. I would very much do so, but can't make heads or tails from what I've read (although I have quite some experience in flashing the HTC HD2).
I was wondering if there is a step by step tutorial which describes everything in this thread?
Would very much appreciate it.
Thanks a lot!
