LG OPTIMUS L9 P769 20H
(ROOTED)
 
You can search the All Things Root forum on how to unbrick the phone. I think this may be the most discussed of the threads on the issue:

http://androidforums.com/optimus-l9-all-things-root/774474-deleted-framework-res-apk.html

I'm sure there are more threads on other forums like XDA or the other Phandroid forums on phones with similar issues of being stuck in the boot logo. If you have no way of getting into that S/W download mode on your phone, it may be bricked for good. Good luck, and if you manage to fix this, DON'T install Chainfire 3D on JellyBean again!

i am trying to flash V10D_00.kdz into lg support tool or r&d test tool (sorry I'm nooby with this) but it seems that when i connect my phone into s/w mode or download mode , my computer dosent reads it i just says usb device not recognized. the lg support tool or r&d test tool stops at 15% to connect my phone.

Please i need help ASAP , im still paying for this phone and theres no point of paying it if i can't use it.

sorry for my bad english
 
I've never had to go through that process with this phone so I wouldn't know what to suggest. Perhaps for that it would be better searching for other LG phone threads that have similar issues with the LG Support Tool.

Click to expand...
well i deleted them all , but the drivers i had was
-Lg mobile driver
-Lg United Mobile
-Lg VZW_United_WHQL

do i need a certain driver to get my phone to recognize my phone to pc
because it only connects when its in lg logo when i turn it on but when i put it into download mode it dosent
 
So i stupidly installed chainfire 3d restarting my phone to a boot loop, i tried doing a hard reset still it restarted back to boot loop , I tried flashing a stock rom/kdz for my phone into lg support tool/r&d test tool, but every time i put it into s/w upgrade mode my pc dosent recognize it, it just says Usb device Not recognize , it also says device driver software was not successful , and i did
try installing my phone driver from here (LG P769 Support: Find Manuals & Warranty Info | LG USA) but yet it still dosent recognize it. I think this is the only problem thats blocking my way to unbrick my phone. I don't know if I'm installing the wrong driver or my phone.

If you know the right driver for my phone can you please reply with the link, I would be appreciated for your help.

my phone is also locked boot loader.

sorry for my bad english
 
Hopefully having your multiple threads about the same issue merged together and put in the correct forum will help.

Good luck:)
 
It's fair to note that this phone is losing the attention it had for the past two years or so. Many people have moved on to other phones, so it will become more difficult to get timely responses as the weeks pass.
 
Hello everyone I am very new to this area of computing (and this forum). However I have still ended up in the same hole as you guys are describing although it happened for a completely different reason. (BTW: I am rooted)

one day I tryed to play the android game NOVA 3 on my Nexus 7 on the highest graphical setting so I went and researched how to do this. I was pointed towards some kind of app called 'ChainFire 3D', Once I pressed the install button inside this app the Nexus 7 switched off and the next time I tried to turn it on I got the X logo of death (boot loop). I then tried to enter recovery and I got the annoying 'no command' error. I cant seem to remember how I rooted this thing but I do have access to the fastboot stuff ONLY (inside cmd).

if there is anyone who has any idea how to go about fixing such an issue without wiping everything on my nexus could they please get back to me ASAP.

ill tell your all the information i did with this phone
 
Hi @alohaillest,
did you try this (from other forum) ?
Did you install recovery? If yes, go to recovery mode, mount /system, run adb shell from computer and type these command:

Code: 
su

cd /system/lib

sh ./cf3d_uninstall.sh

It'll run that script and uninstall CF3D from your phone.

Cheers. Good luck.

Been months since even trying anything with this phone after figuring out it has encrypted bootloader so don't remember all the errors trying to flash kdz's off top of my head so can't help you on that exact problem.. Little more work but worth a shot.. Haven't personally tested it but good feedback on XDA.. Make sure to follow all the steps.. Skim through the thread for any updates and what not.. Might get around the LG Support Tool Issue.. Already bricked so can't really hurt..

[BIN]{LGFlashTool} Unbrick/Unroot/Flash ANY (P769, MS769, P760) in Download Mode - xda-developers

actually, just noticed the driver part too (was on phone so just saw the 15% and an error).. try uninstalling the drivers, then run the driver install from lg again.. maybe it will pick it up..

EditEdit: Might want to read around in XDA L9 forums.. they are still alot more active
