Bricked P768 after downgrade for ICS - LG Optimus L9 P760, P765, P768, P769

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?

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

Help me fix my phone?

Afternoon guys, so today, I finally found my phone. I moved out this previous weekend and I left it at my old place, my friends figured it'd be hilarious to post something on Facebook or send people texts from my phone, but locked themselves out, and then apparently attempted to restart in recovery mode. Now it's stuck on the LG logo, it's not seen by my computer by LG's software, or KDZ, and I don't want to take it back to the shop and get it replaced because it has all of my stuff on it (And it was rooted with Cyanogenmod installed) Anyone have any other suggestions? Do you think the store will find out or even care if I had Cyanogen installed?
Cheers, Chris.
Also, I apologize in advance if this thread is in the wrong place.
1.does it boot in recovery or not. If it does there is no problem
2.Have you tried wiping dalvik cache and data.
3.you can flash another rom it boots in recovery
Attempt Further
Try all SWISS ARMY methods ;-)
Can you get into RECOVERY???
If so try wiping CACHE,DALVIK,BAT STATS then reboot..else
You can use option MOUNT USB STORAGE(when connected to pc)
and COPY files from sd to pc.
After that Flash a new ROM after a HARD RESET

No, doesn't boot at all, stuck on the LG logo.
I haven't wiped any caches, I don't have a clue how.
I can get it into Emergency Mode, but KDZ isn't finding the phone, with the modem disabled. The LG software wont update, says there's a problem with the connection between the phone and the computer (My guess would be that it doesn't like Emergency Mode). Does it want a recovery image to be on the SD card?It'd be my first point of call, but I don't have an SD card reader on hand, but if that's all it wants, I could probably find one around.
I usually work with computers, not phones, and to my understanding, this could all be resolved by resetting the bios/removing the CMOS battery for 5 minutes, is there a way to do this on my phone?
do you have lg united drivers because kdz updater picks up the phone even while booting and also if phone is off .
dont use the computer scienve in phones..
what mode are u using in kdz updater
thank me please....

HARD RESET is like removing CMOS battery... but it reverts phone back to ORIGINAL STATE n you will lose all your data and apps..
So Backup all data in SD then PERFORM Hard Reset by:
Pressing Home+Vol.Down+Power
(CAUTION:HARD RESET DELETE ALL USER DATA

I've read the other threads, and they all say that it's usually the Modem driver, but I've made sure that it's disabled, and the battery's out, so it's getting power from the USB, so I don't think it can be the cable.
u didnt explain what is happening
1when you press power button it gets stuck on lg or what
2 when you press vol up + home + power what happens
you didnt tell correctly

Its like removing CMOS battery of your pc.
But in PC, BIOS Settings are reverted to DEFAULT and OS is not harmed.
Here, Your phone will appear as if you just powered it up after FLASHING CM7

One thing you can always do is brick your phone and take it to lg ppl and say i was playing a game suddenly my phone switched off do this only if in warranty!
or
DO NOT PLUG IN YOUR PHONE UNTIL STEP 3!
1. Went to system restore in windows(you'll find it under Backup and Restore in the Control Panel) and restore your computer to a state before installing any drivers for your phone.
2. After everything had completed, installed LG Mobile update. There is an option to install general USB drivers for your phone, DO NOT do it! Go to Customer Support > Application, Manual & USB driver download. Input your IMEI number from behind the battery in the back of your phone(or just select the "Read your phone" option if you can get it to read your phone). It will search and return the correct drivers for your exact phone. Download and install your USB drivers.
3. Keep your phone disconnected from your PC, and start up LG mobile update again. Connect your phone, LG mobile update should verify the connection by trying to connect to your phone, checking software versions, etc. It will connect even if you are stuck at the LG screen.
4. If everything checks out run KDZ updater and flash your phone back to original specs.
try this this uses lg updater instead of kdz updater
have you flashed a .32 kernel on .35 rom or vice versa?
Press thanx if i helped you..

[Q] Bootloader Encrypting Error | L9 P760

Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.
I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open

I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

[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.

[SOLVED] Need to flash System partition through fastboot

Hello.
I recently sold this phone and went to factory reset. no problem. However, i forget i deleted the STOCK home app. THere is no launcher on the device so LG Setup Wizard simply crashes when finished setting it up. There is NO ADB since the setting has been erased. I need to re-enable it in settings but can't get that far since LG Setup Wizard keeps crashing..
I think i'm screwed.. what a stupid way to brick..
Device is: LG Optimus L9 P769 T-Mobile variant. Thanks guys!
you should be able to put your device on download/emergency mode and flash a kdz file with lg tool, you tried it?
if don't try yet, take out your battery, hold + volumen botton and put your battery again holding even + volumen key, and conect your to your computer, it must show the yellow screen with the legend download/emergency mode, and in your computer must be install the drivers, to exit the download/emergency mode just take out the battery or hold the power button, and for flash a kdz file, search a tuto, there are many, and many videos to make it easy . All this process let your device as new, all applications and configurations
I am aware of that mode but when attempting to flash that way before, after upgrading to jellybean, it would never flash for me. So I didn't even try it. I'll give it a shot though. I also was able to download one of the cwm backup zips posted in the other thread and extracted the system partition then created a .img image out of it and will try both your method and flashing that img file when I get home from work. Thank you for your post!

SOLUTION
Installed the ICS uboot.
Booted to SW Upgrade mode via plug USB, hold volume up button, place battery into device
Launched KDZ update tool and it connected and went smoothly!
If you have the JellyBean uboot, it won't connect in SW Upgrade mode if booted manually.
