[Q] Can this Unbrick method be aplied on L9? - LG Optimus L9 P760, P765, P768, P769

so im on a hard brick (no light buttons, no vibration, no s/w mode) when i tried to root the device with ics and p768g, the thing is that even dead like it is, the LG moible suport tool detect the device, read imei but in the middle of the upgrading process, i get a conection with device error, so i plug out and in and the process keep going and eventually it ends but everthing is the same, no boot.
i found this link http://forum.cyanogenmod.com/topic/71825-hard-brick-to-hell-and-back-guide-to-recovery/ of another device but the concept can be aply to the L9?
thnks in advance

Chances are you're not actually hard bricked. It sounds like your drivers aren't installed, try installing them again (which I admit, was a huge pain in the ass for me). Also, try removing your phones battery while its unplugged, hold the volume up and down buttons (or power and volume down. I forgot the combination for this phone) then plug it into your PC. This should start s/w upgrade mode.

[Q] How bad can brick be?

I've read some people who have tried rooted there phones have completely bricked the phone to the point they cant restore it? Is this really possible? Because i have had my phone for some time now, and am thinking of rooting but dont want to break it...
Thanks
If you get the Phone ---> Computer screen and you have locked hardware access, there is no fix for it right now (unless you're lucky and somehow get adb to work).
If your phone can get to download/recovery mode from a powered down state (using the physical buttons) then its pretty much unbrickable.
Edit: I have locked hardware access and I rooted my phone. It seems pretty low-risk as far as I can tell.
it really only happens to people who can't properly read instructions right or when they're flashing things labeled 'BETA'.. i would personally attempt to get into download mode using physical buttons, if you're able to do that and you know how to flash back to stock using Odin.. you're fine, search the forum for instructions on getting to Download mode.
Being rooted will have NO risk of bricking your phone.
It's flashing custom roms and such that poses the risk.
I'm glad my Vibrant isn't hardware locked like the newer ones. I got the Phone--Computer error when flashing the gps fix/beta rom. Luckily, it was super easy to fix, but if I couldn't use the volume buttons it's impossible.
So, if you want to get root to do things like share your wifi or have adblocking on your phone, you'll have no real risk, but flash at your own risk.
Edit:
See if you can get into download mode by using your hardware buttons.
Turn your phone off
Plug into USB on your computer
Wait until battery status comes up
Hold down both volume keys and power. When powered up, stop hitting power.
If you get into download mode, your chances of actually bricking your phone are significantly lower than they would be if you couldn't. Not 0%, but definitely a lot better odds going in your favor.
The software really should've been called Loki because it's a tricky bastard and just likes to randomly screw you over.
EDIT2:
OK, Turns out the way I suggested you get into download mode is the hard way (it was how I learned to do it).
The EASY way is to plug your USB cable into the computer but NOT the PC.
Turn off your phone.
Hold down both volume keys and plug the USB in.
The phone should power up in download mode without you even needing to hit power.
ok but is there a difference between download and recovery
- Recover shows you a nice menu with a few options.
Allows user to use menus with the use of his Vol +/- and power button
- Download shows a HUGE triangle with an android digging with a shovel and says download
Normally used to flash with ODIN

Reading and understanding instructions will almost always prevent this ..... taking some time to research the basics is a plus....
ROOTING never causes bricking .,..,.,. USER error is the culprit 100% of the time ....
"completely bricked the phone to the point they cant restore it"
You said it .,.,. this is what is ment by bricked *no boot at all*.. only way to fix on some devices is by the use of Jtags(See xda-WIKI). Only android device that has this option so far is the G1 ( don't know if they got it 100% working yet )... Not being able get into download mode because of locked hardware buttons is not bricked... just got to find a work around ,or find out how they are locking the buttons ...

Bricked P768 after downgrade for ICS

hi guys, I think my P768 is bricked = '(
he was V10A, I installed v20a on it, I installed the root and cwm. then I flashed back V10A accidentally and now the device is stuck in the recovery screen. The lg updater tool does not recognize it in recovery and when I do power + vol up it also does not work (because of jb i think it) ... I also did hard reset several times, it reboots back to recovery screen, and the flash still doesnt working...
I'm desperate, what do I do?
Edit;nevermind what I wrote before.
Turn off your phone, remove the battery, while holding vol+ &power plug usb cable to the computer, you'll see sw mode, put the battery back in ...
Use original LG tool(lg pc suite). Make sure your hosts file is clean
thanks for the help, but i tried and the tool said "problem with communication between cell phone and pc"... i'm sure that all drivers are installed
sorry for my bad english =/
====
well, i did it and at 15% of analisys the tool said "the usb cable and your cellphone are not connected... please connect and press restart" =/ (i used pc suite also, it didn't recognized anything)
=====
after losing a few hours of sleep worked perfectly in the online tool ... I almost cried with emotion lol, thanks for the Force!!
I have exact issue with 15%. How you sorted it out?
Sent from my Nexus 7 using xda app-developers app
well, remove the exceptions for lg in hosts file, after this restart the pc...
after this power off the phone and connect pressing vol up for s/w upgrade mode. open LGMOBILE SUPPORT TOOL (the same as previously), above the screen click in custtomer support or options, i dont remenber, and look for something similar to emergency flash... after this follow the screens, is simillar to offline flash

[Q] Phone soft-bricked, battery dead

After an unsuccessful CWM flashing attempt, my phone it getting the infamous "SECURITY ERROR" message. Now, I tried the offline KDZ method, but like many other JB users, the flashing got stuck at 15%. So, finally I decided to use the online flashing method using the new LG Support Tool. But the sad part is that I am suffering from a low battery issue.
So, does anyone know how to charge a soft bricked Optimus L9?
Any help would be highly appreciated.
I'm just guessing but you could try removing battery for 15-20 sec then inserting it and connecting your phone to charger. If that doesn't work, try installing x and u using fastboot that try same process with removing battery...
You can always use another phone to charge your battery

I tried the fastboot method too, but I face a problem while doing it. The OAMP device which shows in the devices manager keeps disconnecting and reconnecting. So then I unplugged the USB and clicked on "show hidden devices" and then installed the drivers by clicking on the OAMP shown there. But when I plug in the USB again, the same reconnecting starts happening. Do you know a solution to this?
You should follow this post...
Connecting and disconnecting of OMAP device is normal, but it is important that it's recognized in device manager...
FINALLY UNBRICKED....
Sincere thanks to all those wonderful people who have made so many tutorials. I failed to do the offline KDZ flash as well as the fastboot method (as I have mentioned above). But anyway, I did unbrick my phone. I flashed using the online method as follows:
Download the latest LG Mobile Support Tool.
Connect your phone in "Software Upgrade" mode (by holding the Vol UP button while connecting the USB).
In the LG Tool, click on "Options > Recovery". Getting the recovery to open is a confusing task. You have to fiddle around with the USB Drivers options a bit.
Now, let the LG Tool do it's magic [In my case, it downloaded a 592MB file]
CAUTION: When the upgrade tool is in it's last stage, the phone will restart at around 93%. When it restarts, you quickly need to press and hold the Vol UP button to again enter the "Software Upgrade" mode, otherwise the upgrade will not succeed and you will get an error. If you get that error message, don't worry, the Tool will tell you how to "RETRY" (don't worry, no file will be downloaded from the internet this time )
REGARDING THE BATTERY ISSUE:
When my phone got bricked it was at around 65%. Now, when I finally unbricked it, I am seeing 83%!! So, either the phone charged when it was connected in the "Software Upgrade" mode, or it charged when I plugged the charger in the wall socket for half an hour. In any case, if your battery is dead (and phone is bricked) try to charge using a wall socket first. When you do this, the phone will automatically switch on and you will again get that sad "SECURITY ERROR" message. Just switch off the phone when you get this. Let the phone be plugged in for some time to let it charge. [NOW I AM NOT SAYING THAT IT WILL CHARGE AS I HAVE MENTIONED THE TWO POSSIBLE WAYS ABOVE, but hey, it's worth a try!] If your phone switches on, good job! Otherwise, try to charge via the USB by connecting to your PC/Laptop by going into "Software Upgrade" mode.
I just hope that the above points will help some unlucky soul who was stuck like me Remember, never give up!
Thanks to all for the tips my optimus was running fine at about 65 percent charged and just shut off. I bought a new battery charged all night in the wall still nothing. I can't get my computer to see it. when i hold power and vol down I can hear the computer make sounds like it recognizes it though

I don't think so, just now did it and I can here the computer making sounds like it recognizes it but nothing shows on the phone
p.s. guessing my board went bad, no worries though just first time I ran into something I couldn't fix if the cpu would read it or any software I might have a chance
If you still have warranty you should take your phone to service, if not then try installing fastboot drives and flashing x and u then try offline kdz flash...

well I did the fastboot option i found but not sure if I did it right, I downloaded the omna files but not sure if the right ones but I did get the screen to show a faded out lg symbol not sure if that means anything
Use fastboot from here. You have here how to install fastboot drives. Then follow instructions from this page.
Read instructions carefully and you should be able to successfully unbrick your phone.

[Q] device bricked with no access to recovery

Hey all.
So my friend cried to me as I am the "expert" guy in my friends circle about his phone not functioning. I've tried to search about it, of course, but I am a total noob at phones that aren't Nexus so I'm sorry if I make stupid mistakes.
He told me he was trying to move from Stock to CM11 and that caused to device not booting up (shows a picture of a dead android) and recovery not accessible (says something like "this mode is for data backup.."). He claims he had Root and custom recovery but I'm not sure about his BL status..
When trying to hard reset, it shows a "thinking android" but quickly after it tries to boot and gets to the dead android again. I also tried to connect it to the PC with an LG software but it doesn't recognize it..
I'm pretty much out of ideas and the fact that this phone is not familiar to me doesn't help at all.
Thanks very much in advance, any help will be great.

Hi MasterLinuxer, you could try this:
From cmahendra's guide (FAQ: Frequently Asked Questions) http://forum.xda-developers.com/showthread.php?p=40483954
Download LG Mobile Support Tool and do the following steps:
..1. Remove the battery and the USB cable from phone.
..2. Without the battery, plug the USB cable and connect the PC to the phone with USB cable.
..3. Press and hold (VolumeUp) key and press (Power) key for 2/3 secs. You should see "S/W Upgrade" on the screen after a few seconds.
..4. Re-insert the battery in the phone.
..5. Start LG Mobile Support Tool(B2CAppSetup.exe), let it find the phone (and load drivers) and start the software update.

[Q] Is this recoverable?

So after playing around with some ROMs, flashes and stuff, I managed to brick my LG Optimus G e970. The phone turns on, but nothing shows on the screen, not even if I try recovery mode. I can prove it turns on because when I plug it in to my computer, it responds to the turning on and off of my phone (checking drivers etc.), but I can't see it in My Computer. It seems the only way I can turn it off is by unplugging the battery. Does this sound like something that could be potentially fixed, or is my phone riparoni? Im going on a trip soon, so I may not be able to try out/reply to answers. Just thought I'd ask and see what pops up. Thanks in advance.

Can you get the phone to boot into download mode? This is accomplished by the by switching the phone off, holding both the up and down volume buttons at the same time and lastly inserting the USB cable into your computer. If you can get there then you should be able to return the phone to stock by using a program called LGNPST. Links to both the stock ROM, and instructions for how to use LGNPST can be found in this forum or you can simply Google it. After restoring to stock you can once again begin the process of rooting and unlocking the boot loader of your phone to install custom ROMs, or you can just stay with the stock AT&T Jellybean ROM if you want.
Your golden same thing happened to me.
Hold the power button for a long time until your 110% sure it's off.
Hold VOLUME DOWN and VOLUME UP and POWER until you see download mode.
Download LGNPST and if you need help finding the proper stock .bin to flash I can help. It's super easy process.
