Big problem
Hi! i have a Lg c660 and i'm very sad for this. I have been rooted and then installed ROM MANAGER to make back-up. I changed the backup name, and then i clicked ok. my phone has restarted and no started to make back-up, only LG logo appear on display. I tried emergency mode with kdz but i received error, probably was not correct ROM, I tried to restart the phone, i pull out battery and usb cable and then the phone no start. I was with him at service and a guy repaired the phone with JTAG. Now, the phone rules perfectly, but is locked on fly mode. I can't unselect fly mode. the guy from service said probably is f**ked up the ESF or EFS (i don't know exactly) which include file with GSM network and parameters, Imei, and i can't use the phone to speak at him, only without sim. How can I fix this problem? The phone was bought from Italy.
I'm sorry for my bad english, is not my mother tongue.

what do you mean?
I thought I always start in emergency mode.
well that is what i am doing.
I'm beginning to think that the cable is bad.
PROBLEM SOLVED
1-. The transfer cable driver was installed, otherwise i could not start transfer data:silly:.
2-. The problem was the other driver was not installed (no remember the name). So after successful installation KDZ want to recognize the phone and the driver that i mentioned was no installed, so is pops up error even after install the ROM.
3-. i tried to start the phone and always got stack in the LG logo over and over again .
4-. I did not know this after i downloaded all the diver from here ( search google lg c660h soporte). So i installed the error was disappeared .
5- After no error, the star up still displaying LG logo over over again, so searching i noticed that i was not doing the right hard reset. So i did it (VOL DOWN + HOME + POWER), wait for the android logo and eureka :fingers-crossed:!.
Summarizing
install the proper diver.
do the hard reset.
Cool , saved my phone..
Here's what i did :
install msxml on pc
disable lg modem in device manager
run kdz-fw-upd.exe
choose :
type : 3gqct
phonemode : DIAG
from "kdz file" section choose the KDZ file "V10H_00.kdz"
go to emergency mode in phone "return-up-power button together"
connect usb cable
perform lunch...
Good luck ...

Somebody here sujal's post: http://forum.xda-developers.com/showthread.php?t=878537
Did the same thing I did, then our phones crashed. Anybody got a solution?
Here is where I posted my problem: http://forum.xda-developers.com/showthread.php?t=883314
hey.. I just took it to the LG service center after I got tired of trying for 10 hours straight. They have promised me a brand new phone by thursday. My advice would be that you do the same. If they ask you how it happened and stuff, then tell them that you tried to upgrade to the newer firmware and then that happened. Just don't let them know that you rooted your phone. Good luck!
I got the same situation before while using ROM Manager and Clockwork Mod. All I saw was just the LG blinking at the start up screen.
I brought it to the LG Service and told them that the power was not working. They kept my phone for 24 hours and called back and said that I had upgrated the firmware. I lied to them that I didn't
By the way, they still made the prepairation for you.
PS: I think your situation is that I suppose you read this thread: http://forum.xda-developers.com/showthread.php?t=883314 carefully or if you are not sure what you are going to do, please, take it to LG Guarantee Service.
I really wanted to fix this by myself, but if I cant, I'll be doing the same. The Rom Manager really sucked.
This exact same thing happened to me, I Installed ROM Manager and Clockwork Recovery, then the phone rebooted on its own, and then was stuck on LG Boot logo. I haven't set up custom recovery yet at this point to create a back up, so I thought I was screwed. But I have successfully recovered it.
To recover your phone:
Follow the instructions on the sticked threads about flashing original firmwares: Setup KDZ (or whatever updater), grab your original firmware file, boot into Emergency Mode (I think the key combination is Up+Back key, not sure on top of my head) let the updater flash your firmware, and voila!~
Hope this helps.

Did u follow the exact instructions given here? http://forum.xda-developers.com/showthread.php?t=883314
I didn't have those errors happen to me but I noticed on your 3rd last line it says LoadCDMAPhone() Error, and wondering if you didn't set your phone type as 3GQCT in KDZ Updater. If The_Error's guide doesn't work, I may have to say you're SOL, and should try to return/exchange the phone if you can or send to LG for "warranty" repair.
The clockwork mod does not work on our phone, I was suppose to install this but tried to search if it is compatible with O1 and found out it doesn't.

Try to recovery your phone by LG mobile support tool
1. Download LG mobile support tools from LG web site. http://www.lg.com/us/support-mobile/lg-P769
2. Boot your phone to SW upload mode
3. Start LG mobile support tool.
4. Connect your phone with usb cable. LG mobile support should detect your phone model. If not please reinstall LG usb drivers.
5. In LG mobile support tools, select "Customer support" > "Recover phone"
4. New dialog popup ask for IMEI or S/N. Your IMEI should already fill in textbox just click first button.
5. Wait for LG flash program to load kdz from their server and flash your phone. It should work.
Just put on the Chinese android!!!
All that did was put on the chinese android i need a way to flash it

Once i enter in the correct KDZ file i press start it says unpacking then the prgaram stops working
I have tried this on other computers also
If u can give me a step by step version on how to use the KDZ updater program that would help
My phone is the LG P765 or P760 running Android 4.0.4

Whenever i try to update the recovery using the LG mobile support tool it doesn't recognize my phone. My phone can only access S/W Upgrade mode. I have CWM installed but i can't seem to get access to it. It keeps getting stuck in LG logo but does't go past there.

Then try the method from the link I gave. When u use offline method you 'force' LG mobile support tool to flash kdz file of your choice - it is enough that LG MST sees any phone it can flash - it cannot check online (through IMEI I suppose) phone details.
So first download the stock .kdz of your choice,
In case of program I used and linked, you
- change two files in LG MST on your computer,
- open R&D Test tool
- select kdz file you downloaded
- press 'normal web upgrade test' button, leaving the rest as default
- wait for LG MST which opens and starts the flashing with kdz file you choosed before
Thus it is no point to let LG MST to check your phone in that method.
Before I tried it, the phone, with 'security error' message was not recognized by the PC or LG MST, even in s/w mode.

U've got it in this post as I mentioned and linked before
Hi, first of all i think my issues had already been solved
but for other LG smartphones, not D618.
My problem occurred when I playing around with hidden menu, and I hit reset button on the FOTA menu,
and then my phone restart and stuck in a screen that I never seen before, the screen show three line of text:
● FOTAFS_Open/cache/fota/log/FSUA_LOG_000.txt, 0, No such file
● FOTAFS_Create/cache/fota/log/FSUA_LOG_000.txt, 66, No such file
● FOTAFS_Close 0
So I googled about that and I found on a Vietnamese forum that it can be fix using LG FlashTool. But the problem is the tool need a correct .dll file for each device and I can't find anywhere the exact .dll file for LG G2 Mini D618. So if anyone could provide me the file I will be very thankful coz my phone been dead for 1 day.
I already tried flashing the kdz file, but no luck.
I tried to sideload stock recovery via adb but adb didn't detect my device.
Please help me solving this
Can you turn the power on your d618 for now? and what the displayed of the screen?

Now my phone turn back on to normal, I finally took it to the LG service center, and they replaced my motherboard.
So if any of you guys experienced the same, I'm telling you there's no software solution to fix this, it seems because I rooted the phone and somehow it lock the motherboard when it trying to perfomed a FOTA update.
Recently I brick my lg p500 while reboot in amon ra thunder G recovery . due I have stock ROM already installed I just unrooted phone and went to service center at Bharuch India. They told me it is easier for them to repair and make it working . because we have no opportunity to use now kdz and there no way to save it .
So anyone please tell me the minimum cost of repair asked by lge repair center.
Here they asked me to give 250 INR. I was shocked in greb my phone and ran away from shop because I have not even 10 INR. :crying:

I found after finishing installation my phone was take more time to wake from screen off . I understand that I made a great done .because nothing like this was happened before in stock ROM . I tried to reboot it but stuck at my own added custom animation . as usual I try to go to recovery and delete this animation file . but now I stuck recovery start up text BUILD :RA THUNDER GNM.
God of android come here to help me please
I do not have 250 Rupees to pay them .?
Why can't you use kdz?
I think that you may be able to use it with the bootloader.
Edit: I found out what you need to do.
First, you need to boot to emergency mode.
Instructions are here, it's the same for the Optimus One, so no need to worry.
http://www.ehow.com/how_12314778_boot-emergency-mode-optimus-t.html
Update: Here are more complete instructions.
Make sure you have installed the LG drivers, and you have the kdz file (full image, not just modem).
How to Flashing LG Optimus One back to Original Firmware
Turn off your cellphone
Press and hold Volume[+] + Power + Back buttons, until your Optimus boot in emergency mode
Connect LG Optimus One to PC (via USB)
tips: maybe it`s a little strange to do, but you can try to shake the phone if it can`t detect.
Run KDZ_FW_UPD.exe
Select Type : 3GQCT
Select PhoneMode : DIAG
tips: if this option failed try EMERGENCY or CS_EMERGENCY
At KDZ Files section, select firmware that you already download
Click launch software update button
tips: someone say that it`s good idea to shake your optimus one with gently to avoid stuck.
Wait until it`s done, unplug the usb cable
Press and hold Volume[-] + HOME + Power buttons
See the firmware version, congratulation you did it.

Why can't you use kdz?
I think that you may be able to use it with the bootloader.
Edit: I found out what you need to do.
First, you need to boot to emergency mode.
Instructions are here, it's the same for the Optimus One, so no need to worry.

Update: Here are more complete instructions.
Make sure you have installed the LG drivers, and you have the kdz file (full image, not just modem).
How to Flashing LG Optimus One back to Original Firmware
Turn off your cellphone
Press and hold Volume[+] + Power + Back buttons, until your Optimus boot in emergency mode
Connect LG Optimus One to PC (via USB)
tips: maybe it`s a little strange to do, but you can try to shake the phone if it can`t detect.
Run KDZ_FW_UPD.exe
Select Type : 3GQCT
Select PhoneMode : DIAG
tips: if this option failed try EMERGENCY or CS_EMERGENCY
At KDZ Files section, select firmware that you already download
Click launch software update button
tips: someone say that it`s good idea to shake your optimus one with gently to avoid stuck.
Wait until it`s done, unplug the usb cable

Yes, I did so half a year ago, to update my LG Optimus P500H.
Unfortunately there was no update in Israel, and it's firmware was at one of our cellular providers (Pelephone), so I had to use this method to flash a different country's unlocked firmware (some european firmware, I forget which) with the same bands support in the modem, before flashing CM7.1 and TWRP.
It's just been a long time, that's why I didn't remember how to do it.

It should work with with all P500's, restrictions or no restrictions, it doesn't matter.
I will test on this Sunday. When my laptop comes to home. By the way if it works I promise I will give you 100 Rupiya as donation.
