[LG Optimus G (International)] j0e74:
****UPDATE****

I manage to install the brazilian version of Claro firmware (originally my E977 came with Movistar Centroamerica), but there this thing system only reads 25Gb in the whole, afaik it had 32Gb before I broke the bootloader... Does anyone knows why this?

I rooted with framaroot apk.

Then I unlocked the bootloader with FreeGee apk and installed custom recovery.

Please help

Hi i do all the steps properly, and i right after i click update software it going into not reponding mode whats the problem?
[LG Optimus G (International)] j0e74:
Don't forget to install **msxml.msi** which is inside de KDZ folder you unziped.

Other thing to consider is that I tried to download my service provider .kdz file, but it exceeded 1 Gb and KDZ UPDATER seemed not to tolerate that... so I had to download other .kdz

For example, mine was telefonica centroamerica, but I had to install claro brazil... then I rooted it and unlocked it to change to a custom rom.

Hello i am stuck in bootloader and volume buttons not working, how do i get in recovery or downloadmode.

I have searched google trying to get the laptop recognize my phone.

But the laptop sees the phone as android with no drivers.

Please if someone can help me out.

Thanks in advance.
[LG Optimus G (International)] atifsh:
In stock bootloader page doesn't change when you press volume keys. Just press volume down once and than power.

If your volume keys are bad, goto download mode and flash kdz.
[LG Optimus G (International)] Felrhoul:
Solved it with flashing image file with fastboot.

Thanks for the reply
[LG Optimus G (International)] pjsolanki:
Brother if you're a newbie just press and hold the volume up and down keys and open the lg support tool on your computer then connect the phone to the pc. now go to option update recovery and hopefully you'll be back to the stock.

OMG man you saved me. I tried to root my wife's phone and got it soft bricked http://xdaforums.com/images/smilies/mad.gif

Thanks to you got it back to life within an hour. I had to download KDZ file from LG directly. But everything worked on E973, from Telus.
[LG Optimus G (International)] Sofacykel:
Had some hiccups with the LG Updater but that was due to the XML Parser (included package) not being installed, and.. well, Windows 8 being Windows 8. Worked flawless on my Windows 7 machine.

I was seriously about to poop out an elf when I bricked this unit. Turned on my PC and looked for a guide on XDA, and lo' and behold here I am.

Thank you very much for taking your time to make this guide.

To everyone else:

The IMEI and S/N are usually on your contracts, boxes, but also on a tiny label on the phone. I couldn't read it, even with hefty lights on it, but what I found was that if you shine light through it (from behind) it turns out pretty readable.

Remember to install the XML Parser (msxml) included in the updater zip.

To turn on your phone i Download Mode: Volume Up + Volume Down, but don't press the power button! This isn't an HTC or Samsung phone (took me a lot of time to figure this one out...). Just plug it in while holding the volume buttons.

Remember to install the LG United drivers, otherwise your phone won't be recognised in Recovery Mode.

That is all. Thank you all for one of the best online communities this world has to offer.

So after installing CWM Recovery 6.0.4.7 via Freegee, in recovery mode I performed the following steps:^

1) Did a wipe data/factory reset;

2)installed the latest CM 11 nightly ROM;

3) flashed Gapps package (PA gapps or something like that)

4) flashed the 4.4 kernel with that package, I can't recall the title now.

My device is E977.

The issue is that now the phone is stuck in bootloader screen (Google logo with unlocked padlock on the bottom). CWM Recovery still works thoug, what can I do now to boot normally with CyanogenMod ROM? Onçy reflashing original KDZ firmware?

EDIT: nevermind, I really messed the files, this kernel has nothing to do with CM ROM, and the gapps package was the wrong one, it was forJB 4.3 while I flashed 4.4.2 ROM. I reflashed the stock ROM and redone the process, CM is working fine here. Sorry for being a noob and not reading the FAQs, I learnt the lesson now.

[LG Optimus G (International)] Shadownn:
Say hello from venezuela.. this post is old but i get the same problem on my phone.. i get the solution... well i think the problem is that bootloader where get the option " START, POWER OFF, Enter Recovery or FASTBOOT." , cuz before i have another bootloader (Not say START, POWER OFF, Enter Recovery or FASTBOOT) and i can install this kdz. well the solution is simple .. when your phone reboot and get the bootloader you select POWER OFF and fastly you enter on DOWNLOAD MODE (not disconnect the phone) later the program software update continue with the update..

Explanation : I not a expert but i see in the program he call a fuction "call fn_StartUpgrade" and here reboot the phone.. if you wait many time get error cuz i imagine the program dont can get download mode again.. where i think "if i put the phone so fast and get Download mode manualy" and PFFF work..

well i dont not why it happened .. expert can explain more?

Desperate.. Stuck in bootloop, windows can't identify device

I'm lost here. I was running Mahdi and AxxionKat ROMs for months, but could never get a GSP lock. So I flashed a stock ZV9 ROM, and that was fine. I then went through the system menu and downloaded an OTA ZVB update. When I clicked install, the phone restarted in recovery, and I haven't been able to get it out. Tried re-flashing Mahdi, and the stock ZV9 ROM, and still end up in recovery every time.

The real issue now, is that my PC (Windows 7) can no longer install the drivers for the phone. I have installed the most up to date drivers from LG multiple times, and get nothing. I tried manually assigning the drivers to the "unkown device," and this failed. I know that either Mahdi or AxxionKat changed my phone name in settigs to "LGE-Gee" instead of "LS970." Could this be the problem? Either way, WHAT DO I DO?! PLEASE!!! SOMEBODY!!!!
