you have to turn off the phone,then do as i said.

But again, what did you do exactly that messed up your phone?Please, more details, as much as you can.If you can't enter download mode,i'm afraid it's a hard brick.

If you turn off the phone and plug the charger in, does it show the charging animation?
[LG Optimus G (International)] Szwarcu:
I already wrote that my phone is dead. I can't turn it off because i can't even turn it on :P

I Root'd. Everything was fine. I was playing Dead Trigger for like an hour. Then i decided to unlock bootloader.

I unlocked, restarted, and still everything was fine. Then i decided to enter the recovery to make a backup, but I couldn't. Phone just started normaly.

So i found this

su
dd of=/dev/block/mmcblk0p3 seek=6144 bs=1
reboot

this supposed to reboot and enter recovery mode but instead phone died after that ....

I can't seem to get the KDZ downloader to work. Is there any way someone can post a mirror to a KDZ for the E970?
[LG Optimus G (International)] Szwarcu:
install msxml which is inside a folder with KDZ
[LG Optimus G (International)] kimitza:
And why didn't you made the normal nandroid backup, in CWM?i don't know why you people like to complicate simple things.

enter recovery,make the backup, reboob and that's it.

Fastest solution for you, JTAG it.Go to a service and that's it.it will cost you,but....

Help to unbrick my LG E975

I need help.

I flashed my korean F180L with E975 kdz and then restored baseband to have signal.

I forgot and restored factory seettings in my setting menu and now the phone doesn´t boot and can´t put in download mode.

Since I press the volume - it appears the messages:

Secure booting error!

Cause: boot certification verify

Can anyone help me please?
[LG Optimus G (International)] kimitza:
turn off phone, then press vol up+vol down.while pressing these 2 buttons,plug the micro usb cable.this way you will enter in download mode.after that, use kdz updater to flash whatever rom you want.

as long as the phone starts,you can enter download mode.

---------- Post added at 10:45 PM ---------- Previous post was at 10:41 PM ----------

if you couldn't enter cwm, it means you didn't unlocked the bootloader.and don't tell me you did, because i can make a video with the same problems you had.i would bet all my money on it.i know because it happened to me the first time i rooted my e975.freegee was not available yet,so i wanted to see how much i can do without it.but i never tried adb commands,since i know how dangerous they are,not to mention i don't master adb that well.now, jtag it.

When the log got to "Call nf_startUpgrade" my phone kept returning to the FREEGEE recovery start page and then i got an error prompt. To fix this i quickly unplugged the phone form the pc at this point. In a hurry i powered the phone off and connected it again in download mode!

For those people who has the error while using kdz updater use a < 1gb kdz, the weight of the singapore kdz is 965 mb and it works (only for E975[k,R],E976,E977,E987), someone corretc me if i'm wrong because all that models have the same specs except the lte band and thats not a problem
[LG Optimus G (International)] cwaffles:
The wipe script did absolutlely nothing for me.

Turning the phone off, holding Volume Down Key + Power/Lock Key at the same time allowed me to go to factory reset and make the phone bootable.

unbrick optimus g e077

Do this steps only for unbrick ypur LG optimus G E977

1 Make sure you have LG United Drivers already installed, otherwise download from below

2 Download Lg pc suite

3 Put your Optimus G into Download Mode by switching it off, attaching the usb cable to the phone, holding both the up and down volume buttons at the same time and lastly inserting the usb cable into the computer; wait for the drivers to finish loading if doing it for the first time.

4 whe you phones conect to pc suite then go to software update and select the las option (recovery mode)

5 Click check in the first option. the program will close and a new one will open,wait for the flash process to finish.

6 you must have a internet conection, the whole process takes an hour or less. the phone will reboot when finish.

I had the same problem and solved it this way. I'm from Puerto Rico and my phone is optimus g E977 claro pr
[LG Optimus G (International)] LRC1710:
is there any other way to reboot into download mode? I just wanna go back to stock firmware but I cant get it to download mode, I turn off the phone, hold both volume up and down, connect the usb cable, nothing happens, the phone suffers to boot normally, bu after a few power button pressing it boots and I can use my rom normally, but impossible to get to download mode, HELP!

hi when you restored the original rom with the lg pc suite the rom that you got on your phone was the operator mobile? the claro rom?

cuando restauraste la rom original con el lg pc suite tuviste de nuevo la rom de tu operadora? la de claro? o tuviste una rom android sola sin modificaciones de operador? yo quisiera tener una que no tuviera nada de movistar soy de Venezuela y tambien tengo el E977
[LG Optimus G (International)] LRC1710:
The OP doesnt specify if this wipes all your device, I did it, and now I lost everythinhg, my photos, my music, my conversations and every other piece of information I had on my phone, thank god I had almost everything backed up, but please add to the OP that this WIPES EVERYTHING IN YOUR DEVICE, is very irresponsible for you not to put it...
[LG Optimus G (International)] chadouming:
Step 11 and 12 talk about wiping, I think it means the device will be wiped when the op says :

Your phone will auto reboot when wiped and (hopefully) boot as per normal.
[LG Optimus G (International)] tommyrumbler:
and the OP is responsible for wiping all data in your device, this after helping save yourASS from having a bricked device? i see you got helped but didn't even pressed "THANKS" button. and the OP you say is irresponsible? W O W !
[LG Optimus G (International)] koquipr:
in my case (claro) original rom
[LG Optimus G (International)] LRC1710:
First, this didn't unbrick my device, the only thing I gained from this method is losing all my data on my phone, second of all, yes it is irresponsible not to specify something as crucial as this in the OP, I had 20gb of internal storage LOST! thank god I backed up most of it before, but it is important that they put so in the future people wont lose their stuff, if this method works for them, for me it didnt work, no harm feelings or anything...

Btw why can't we flash a kdz that is more than 1gb? I see is a main issue all over the internet, hopefully they'll make a fix for it, most firmwares now are 1gb+

Stuck on down Download Mode...

Hi everybody!

First of all I would like to thank all of you for all the tips you give here.:good:

Second, I bricked my E-975 yesterday when I tried to install a custom ROM.

Rooting with Motochopper was a walk in the park and installing ClockworkMod's Rom Manager was also easy enough.

The problem started when I tried to reboot my phone in "Recovery Mode", got the LG logo and a message saying:

"Secure Booting Error!

Cause: boot certification verify"

Now I have tried all the tips and steps in this thread and so far I have managed to start the phone in Download Mode.

I get to step *6 and everytime I will get the same message: Phone Not Found! :(:confused:

I have tried all the other tips here but nothing seems to work...

As additional information my phone is an LG-E975 European (Swedish) modell.

Can anyone please help me or do I have to take my phone to the shop and get it repaired?

Thanks in advance
[LG Optimus G (International)] xodeus:
As long as you can get your phone in download mode then you should be able to flash.

Then I think it's a driver issue on your computer. Try to reinstall the LG drivers. Reboot and try to connect your phone again. Wait for the drivers to install properly and try to flash again.

[LG Optimus G (International)] Scott Chenoa:
I have reinstalled and rebooted my laptop several times now but it makes no difference.

When you say "Wait for the drivers to install properly", how do you mean?

Right now my phone is connected and in Download Mode, I have downloaded all the files from post 1 again and tried to follow every step as good as I can and now I'm thinking maybe I am too old (50 yrs) to understand all this new technology or if it's because I'm Swedish and not quite understand everything in the English language :confused:

Anyway, I will try and try and try until I get it right.

Just talked to a repairshop in Sweden, replacing the motherboard will cost about 2000 SEK, that's about 200 Euro :(
[LG Optimus G (International)] Scott Chenoa:

I did and everything went like a dream.

I got the same error ; just restart your PC , and try again . KDZ updater worked just fine after that . IF you are planning to root the device and flash with custom rom try this :

* Flash with E97510E.kdz (India version)

* Root with Motochopper method

* Run freegee (dl from play store) on phone - Reboot into recovery and flash the rom of your choice.

Tried this method few times and works flawless.

LG Optimus G E977 - Blank screen boot sequence

Hello Guys!

How r u doing?

Please pardon me if i write something wrong, I´m from Brazil and english is not my mother language.

This is my first post here and i have a big problem with my LG Optimus G E977 - Brazilian version

So, after some error trying to change the recovery from CWM to TWRP with Freegee, my LG Optimus was corrupted...

No, I´m not blaming anyone. I accepted the risk... I just want a little help.

So it stuck on the LG Logo and i flashed a rom with the KDZ updater. And it works now, more or less... i will explain:

So, Here is the situation:

It boots up normally, but can´t see a thing,

No Lg Logo, no fastboot, no recovery, nothing, while it boots up, only the sounds ....

Finishing the boot, i hear the sound of the rom starting, still no screen, only sounds, then the front buttons flash, still no screen :crying:

So i press the power button twice, then the screen shows :D .And after that, it works normally, no bugs, no glitches, rooted , everything ...

If i Shutdown the phone, it shows the shutdown sequence, no problems at all

I can get to download mode, although i still dont see a thing in the screen, i only know it´s on download mode because the computer views it on LGPSNT or KDZ updater, already tried teeny bin or flashing the rom again with kdz, still no boot sequence show...

There is other thing too: This rom i´m using is of a diferent vendor of this original LG, for some reason the KDZ file i have from his original vendor doesn´t install, already tried to download it 3 times, always KDZ error on file extract.

Can anyone provide me with a solution? Much thanks to u all

:good:
[LG Optimus G (International)] ggesteira:
Fala jonnhy eu se fosse você faria os seguintes procedimentos.

1 - root novamente

2 - destravar o bootloader com o fregee

3 - instalar o mesmo recovery que estava antes

4 - fazer um full wipe (factory + cache + davlik) e format system

5 - deixar em modo download e conectar no LG suporte tool e fazer a recuperação, aí você vai pegar a versão stock 10b novamente.
[LG Optimus G (International)] hv6478:
MESSAGE TO ALL

I've seen on a couple occasions that this was the case for others as well. This guide is amazing, very clear and very accurate, except for ONE main thing. In the options of the KDZ Updater, you must choose "EMERGENCY", NOT "CS_EMERGENCY", otherwise it ALWAYS results in the error "MOD UpTestEX MFC Application has stopped working."

The application WILL show "Not Responding" as it starts, but don't worry, it will continue properly and do what you need. Wait ALL the way until it says wParam=2001, IParam=1 *EVEN THOUGH THE PHONE WILL START UP BEFORE THAT, IT IS NOT FINISHED YET, YOU MUST WAIT UNTIL wParam=2001, IParam=1 IS DISPLAYED BEFORE EXITING THE APP OR DISCONNECTING YOUR PHONE*

With these steps I was able to get this going in a flash (no pun intended)!

P.S. I used to be around the forums a lot when I had an HTC One X, but it saw its demise a while ago and I have just now been able to get back to Android. I'll try to help when I can, but I am by no means an expert, just a nerd lol.

Happy saving guys!

LG unbricking project coming soon. Currently unbricking phones when someone donates too the project.
[LG Optimus G (International)] hv6478:
I now seem to be having a problem.

After I flashed 4.2.2 AOKP for the E970, my phone got locked on a blank screen right after the LG logo. I managed to get it into download mode and thought that would be just fine, but it got stuck at the LG screen afterwards (unlike any other time, data partition issue as it seems). I managed to get it into recovery mode, plugged it in, ran the wipe.bat, in a second or 2 the phone reboots and goes to the exact screen in that picture.

I have no idea what else to try, having trouble finding any info on it otherwise. I can't seem to get back into TWRP (although I was able to a little while ago, oddly enough). When I was in TWRP before, I would constantly get failures when trying to install a ROM or restore a backup.

Hopefully someone can help or has been faced with this before too!

---

EDIT:

Missed the part about factory reset. I've tried to enter it with volume down + power so many times but have not been able to get it. Is there any special trick to it?
[LG Optimus G (International)] tommyjoesanders:
adb reboot recovery. Hopefully you have usb debugging on
[LG Optimus G (International)] hv6478:
I can't even boot into any system, but USB debugging was definitely on in the system before this happened (although I doubt that makes a difference since the KDZ file was written to the phone already). I don't know how else I could connect the phone through adb and send it commands.
[LG Optimus G (International)] tommyjoesanders:
I know your phone isn't bricked. But you may want too think about flashing back too factory using the firmware. too avoid any more issues. just a thought. I don't use KDZ for this method I use LGFlashTool with official firmware and official DLL.
[LG Optimus G (International)] MitoTakatori:
What can I do if the PC does not detect my phone? I can enable it in download mode. But the PC cant detect it. I already installed the drivers.
[LG Optimus G (International)] tommyjoesanders:
If you have the firmware and can get it into download mode, just flash firmware . Just look at unbricking guide based on your phone model
[LG Optimus G (International)] Jonhny:
Tried, but ...

Obrigado por responder! Thks!

Tried these steps, but can´t see the recovery screen, but it looks like the phone is in the recovery mode... cause it does not boot up.

Tentei esses passos, tudo certo, 100% e não obtive nenhuma, mensagem de erro, mas não consigo ver a tela de recovery, no caso CWM, mas parece que ele está na recovery, porque ele fica travado e não boota normalmente

Tentei acessar o recovery pelo Rom Manager, mas sem sucesso...

Alguma dica?
[LG Optimus G (International)] hv6478:
It may be detecting. After you plug it in, go to Device Manager (right-click Computer > Manage > Device Manager for Windows 7) and check if there is a section called "Modems". If so, expand it, you should see an LG device there, if you do you're good. I recommend right-clicking that device and clicking "Disable" before doing the KDZ method, seems to help.

---------- Post added at 01:27 PM ---------- Previous post was at 12:55 PM ----------

I had tried that already, when I got stuck at the LG screen after. I couldn't seem to get to the stock recovery. I decided to simply try it again, got to the same LG screen, and I was abnle to force it off then into stock recovery!! Performed a factory reset, now back to stock 4.0.4, fresh start!

I find the KDZ_UPD method works fantastically. Just gotta remember to have drivers installed, turn on Windows Enabler (double click then go into the system tray and double click the icon there, you'll see an "On" overlay), then run it with "EMERGENCY" as opposed to "CS_EMERGENCY".

The nice thing is, usually that methoid alone works (if your data partition isn't corrupt). But, if it is, and the auto-wipe doesn't work, this factory reset method is basically fail-safe.
[LG Optimus G (International)] Balano:
I have the E975. I get port or device not found during kdz flash.
