Hi everyone, i'm new in the forum, my name is Edoardo and I'm from Italy.
Yesterday i tried to unbrick my LG P760, and I did it, getting in the Security Error screen.
So i tried to flash the default firmware with KDZ (V20C),i set emergency, boot the SW Upgrade mode on my phone and then clicked on launch update.
my phone stays on for a while, and when kdz says unpacking kdz, after about a minute the phone power off.
i tried with lg mobile support tool, at 15% same problem.
for the unbrick i used this on Win7: http://forum.xda-developers.com/showthread.php?t=2411265_
and it worked.
what should i do now? the phone was rooted, and with CWM recovery. the night before the total brick (if it matters) my contact numbers disappeared, so i shutdown the phone, and then power on, with the result of a black screen with this text:
-----------------------------------
Secure boot unsuccessful!
Cause:
-----------------------------------
Sorry for my english.

Hi, i've a strange (but i hope common and resolvable) problem.
After all, i say that i searched through the forum (with the search function) but with the solution that i found and tried i didn't solve anything.
I start saying that i got a p500 with a broken sdcard reader board (it simply doesn't have a microsd 'cause doesn't recognize).
That phone some days ago just shut down and went stuck on the LG Logo.
I tried at first the hard reset (home+vlm down+pwr), nothing happens.
I tried then the recovery mode and try to update with lg updater, and didn't work, lg doesn't recognize the phone on the updater (but on the main screen of the BBc app does).
After some tries, (dumb tries, for example leaving it without battery for some hours), and searching, i did two ways:
-KDZ Firmware update way, selecting 3gqtc and diag on lg logo, or recovery (and recovery sc) on recovery screen, nothing done.
-LGMDP for installing fastboot and CWM and v20e. It completes the operation but nothing changes, the lg is still stuck on the lg logo.
The last thing that i noticed is that one time, powering on the phone, button's leds flashed about 4-5 times. but if i try to re-do the action, doesn't get anymore.
I would know if there is another way to exit from this stuck-screen.
I hope opened the topic on the right section.

When you say recovery and recovery sc, you mean EMERGENCY and CS_EMERGENCY, right?
So, you tried selecting these options while on the black menu of recovery (like the Clockworkmod one) or on the yellow screen saying Emergency Mode!! ?
In case you were on the recovery, try the following: remove the battery and, while holding the volume up and back keys, connect the phone to USB. After that, try using KDZ selecting EMERGENCY.
But in the case you were correctly on the emergency mode and just used the wrong words here, then I'm sorry but I don't know what else you could try to solve your problem (wait and see what other ideas people will come up with).

Yup, sry it's late night and i got confused with words.
I'm can go on the yellow screen and "EMERGENCY MODE" is texted on center.
And on KFC Used both modes of emergency (even diag).
I tried to do this without battery, but the result is the same. When it reboots stucks up on the lg logo. =(
Uh, i forgot to post the errors of kdz:
Upgrade error
WParam: 100
LParam: 500

Okay long story short, I attempted to install transparent cm7.2 status bar and phone bricked (fastboot). I fixed it and installed other phone model's cwm with windows cmd command (stupid, I know). After this I'm always stuck at lg screen. Can't get into recovery either. Lg update tool does not find the phone, neither does cmd.exe. I sometimes get the ''colored snow screen'' or whatever I should call it. But it doesnt change the fact that the phone can't be recognized by anything.
What should I do? I ran out of ideas. I can't turn the phone in any mode, it always starts with the lg screen.
bump
bump. dammit, am i really screwed? I managed to get a notification about new hardware installing yesterday but none of the driver stuff I had worked so I left it the way it was and did not install anything afterwards.
I've just entered Emergency Mode!! with volume up+down+plugging into usb. Some driver got installed but there's still no lg stuff in device manager
Completely bricked.
Doesn't turn on at all.
Okay, any excuse I can tell the phone suppliers?
cek recovery
whether you have flash before CWM recovery?
if you might have tried to go to CWM pressing the power + vol down
if you managed to do as they pleased
The phone is a brick. It doesn't turn on in any way. Completely dead. If I could get to CWM I wouldn't be asking for a story to tell the phone suppliers xD
You can use KDZ Updater and also download original lg firmware. All can be found here in this forum.

HELP PLZZZ.....
My son got a LG Optimus P769 for Christmas and tried to uprade to Jellybean 4.3 and managed to get his phone Boot locked (When you turn it on the LG logo goes on and off repeatedly. We can connect to it thru fastboot, but screen is reflected and we can set the phone into S/W Upgrade Mode but we can't figure out what to do from there. Is the phone a lost cause or can it be fixed?
Here is a rough list of what he did:
Used cyanogenMod 10.2 to upgrade to Jellybean 4.3 (Got LG logo with security error when phone turned on).
Used fast boot to erase recovery.img, boot.img, chose option 5 and option 7. (Got flashing LG logo bootlock no security error.)
Here is a rough list of what we tried:
Used fast boot to erase recovery.img, boot.img, chose option 5 and option 7. got flashing LG logo bootlock no security error
Tried to use LGMobile support tool, but it freezes on analyzing phone step.
Tried to use KDZ_FW_UPD_EN to load V20F_00.kdz but get Phone NOT FOUND Error.
Please let me know if there is something else I can do. Thanks in advance.
Use the Lelus fastboot to flash ICS u and x. Good luck!

Hello!
Firstly, i would like to apologize for my English(its not my native language).
Anyways, as mentioned in the title, i get the red triangle after trying to get to the recovery mode(stuck at LG logo when turning the phone on).
I think i have tried almost all the methods, but none of them seem to work(I can get my phone to S/W Upgrade state).
When trying to install the new KDZ with LG Flash Tool, everything is fine until the LGMobile Support Tool launches, after that the errors start to pop up.
Errors i get:
Wait until software extraction is complete(stuck).
Something is wrong with PC, press retry.
Any ideas how to bring my old phone back to life?
Hi all
I have an LG H220 that I am trying to fix.
It boots straight into download mode.
Using the LG flash tool 2014, and a KDZ of the original firmware, it starts doing the firmware update, and the phones screen says "Firmware update, 0%" and shows a Com port. It also shows "rooted" in red letters.
It sits there for 5 minutes or so, and then the LG flash tool says "error, try restarting the phone and trying again".
I can enter factory reset but the phone always ends up booting straight to download mode.
Any help would be appreciated.
