[Q] Stuck at LG logo - LG Optimus L9 P760, P765, P768, P769

Hi all!!
Yesterday i tried to install android 4.4 but the procces didnt succeed, it stuck at. LG boot logo. So i decided to restore my backup in ckockworkmod,it started the process then stopped at the phase "restoring /system" . I waited about a half hour, and because it didnt take the much time before, i took out the battery. I read somewhere that formatting the system partition in cwm could help, so i did that. Then i retried restoring my backup. It stuck at the same phase. Later i downloaded the official kdz, and decided to flash it. I could bring the phone in update mode, but the process stopped at 15% at lg update manager.
At the moment i can get into clockworkmod, but cant restore /system . The update mode is also okay. I dont know that fastboot works or not. I havent tried it yet. Please help me thanks in advance

@trapistasajt
You will need to get fastboot working and use lelus's fastboot script to flash the "u" and "x" loaders for the device and then perform the offline or online flash
http://forum.xda-developers.com/showthread.php?t=2292828
Also as you found out you cannot flash custom roms without ulocking the bootloader first and you cannot use the L9 CWM bootstrap recovery for Locked Bootloaders, too flash custom roms.

try this online flash methode with B2CAppSetup

i had the same probleme and i fixed it .

My bootloader is unlocked. I tried the fast boot method, but it doesnt go further than "Waiting for omap...." . So, i couldnt go into fastboot (probably my fault). Yesterday i sent it to the service. If they notice that my varranty is void (because of the unlocked bl) and send it back, i will try it once more. I would be very thankful if someone could write a noob friendly-fastboot guide. As i read, lots of people are struggling with the same problem. Thanks in advance!!!

You have to use LGMobile Support Tool (Install drivers from it first) Then enter in download mode conecting the phone to pc pressing vol+ and the rest its automatic.

It didnt go further than searching for "omap device", so i couldnt load fast boot, as i said. my phone is still in the service
If they 'll send it back to me, because of unlocked bootloader, i wil try it once more. Any suggestions?

I dont know about fastboot.
LG Mobile support tool let you download the correct drivers. Then connect your phone while u keep pressing vol+ and it enters in SW Upgrade mode. Then just click "additional features" and "upgrade error recovery"

It shows something about firmware ir will restore. Ir will flash the latestbfirmware from original carrier release.
For example i actuallybhave v20L but my original carrier only released v10a. It will restore to v10a

None of them works, other ideas?

This fastboot method worked for me in 5 min, pay close attention to the instructions and it works!
http://androidforums.com/optimus-l9-all-things-root/807569-guide-security-error-fix.html
Spent days with LG update tool which if you read the log has no url for files to download.
Good luck!

I got my phone back from the service. They didnt repair it, because my varranty is void. I tried the methods mentioned above.
First, I tried flashing kdz, (with the solution for post-jb problem), but i couldn't get into S/W mode, which was available before the service.
Second, since i couldn't load S/W mode, the LG upgrader wasn't successfull, too
Third, fastboot still not work.
I am sure, that im not the only person with this problem, since it happened during installing @artas182x 's JB 4.4 rom. Please @artas182x or somebody write a noob-friendly guide/suggestion which may help to unbrick my beloved phone. Thanks!!!!!

I followed the steps given on that thread

But on this step in cmd

it shows < waiting for device >
i too got such problem.
while holding down back +Vol down connect your phone to pc .It will enter into emergency mode.Then your Computer might detect it.
Can anyone of u help me ???? My phone is still stuck with Fastboot mode
Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
Hope this is of some help to you.
Finally, Recovered my phone by flashing KDZ through Emergency mode.. No other method worked..

I had the same worries coz my pc did not detect my device at all..
I was trying to get pass the Fastboot mode.. But in the cmd when i tried to erase and re-install recovery it said waiting for device.. Luckily and finally after many tries i could enter emergency mode. Only then the phone got detected but fastboot didnot work there.. The Only way out was to Do the KDZ flash. I flashed the indian GB V20b and did a hard reset now. Flashed recovery and for now have left it with the stock rom..
I wonder now this problem arises due to custom roms.

this problem was cuz didn't perform the steps carefully.
This can called bricking but not fully . As it can be recovered.
Bricking is when your phone is as useless as a brick.

[Q] [HELP] LG Optimus L9 P769 (TMO) Soft-Brick

OK, I will start off by saying I have (nearly) completely screwed myself.
I have a P769 (TMO; does this mean BK?).
I followed this (http://forum.xda-developers.com/showthread.php?p=38677123http://forum.xda-developers.com/showthread.php?p=38677123) to root the device and successfully made it through (using V20D KDZ).
Then then tried to flash this ROM (http://forum.xda-developers.com/showthread.php?t=2335984). Unforunately, I did not have an unlocked bootloader and now I am receiving a Security Error at boot. Even more unfortunate is that I did NOT do a backup so I am truly in a bad place now.
I tried to run through the first step of rooting but the software will not detect the phone as being connected and tells me to connect the USB cable. I have installed the drivers that are in that post but admittedly I may have updated them after rooting.
At this point I only have access to fastboot so I am trying that method but I cannot find any system.img files to be able to flash the system partition.
What do I do now? Can anyone help me? I have exhausted every Google search and XDA search. I may be missing something but I feel I am in a very bad place now and need to get this phone back up and running.

I am still getting the security error even though other threads said I should be able to get rid of it.
Is it possible to create a custom update.zip to flash with?
When I do the recovery it returns my phone as a P769BKGO if that helps with anything.

I am running 32-bit Windows 7 Professional Service Pack 1. I tried flashing V20D_00.kdz (using the offline flash) as well as the V10G_00.kdz and V10E_00.kdz.
Using the offline flash method I constantly get the error of cannot connect to phone no matter how many times I restart the PC or phone and unplug USB.

All caps, correct.
Should I do fastboot and then run the offline method?
I did do the fastboot then tried the recovery phone option from the support tool.
I did find a recovery I made that included (for some reason) only the recovery and boot.

Don't worry about stock recovery it's useless, just flash ics xloader and uboot http://forum.xda-developers.com/showthread.php?t=2292828 option #5

I'll reboot and then try that again. I'll check back afterwards.
Should I do anything extra like start the offline flash from scratch as far as drivers? I'm not even sure where to begin in regards to what drivers/files to remove.
Thank you! Thank you! Thank you!
Now I just need to figure out the screen calibration.
Also, what can I do with this now? Do I need to unlock the bootloader to load custom ROMs without getting a security error?
Sorry for my lack of knowledge. My last phone was a Bionic and that was the easiest phone to root and add a ROM to.
unfortunately i find myself in this situation
gettin security error after what i assume was me trying to flash on a locked bootloader
anyway, i can't figure this out, the whole flashing fastboot and what not
i read through the readme and installed the drivers for the "other/unknown" device that pops up
this is what i try to do next
open up start.bat
enter 5 and hit enter
remove battery from phone (as instructed) and hit any key
boot phone into sw upgrade (holding vol up and plugging in usb cable)
device seems to be picked up and i see the "wait 5 seconds" (german?) and the image is revered horizontally on my phone
now after 4/5 seconds it says "waiting for device", which then i put the battery in
but NOTHING happens after this, it hangs at "waiting for device"
can someone please tell me what i'm doing wrong?
otherwise i think i'm left with a totally effed lg optimus l9

Odds are, you are doing nothing wrong. Check your android version, if you are on 4.2+ (JellyBean) you can't unlock your bootloader quite yet. Here is the thread you should keep track of at the moment http://forum.xda-developers.com/showthread.php?t=2277639&page=152

I've found that the process completes if you put the battery back in , right after you reconnect the USB.

Nope! I had to do a warranty exchange. I was copying the system image then I thought it finished so I unplugged the phone. May I tried my best to get the phone back but I could only get into fastboot mode, but hey lesson learned. Though I did see this tool that someone here was trying to use to flash bin and fls files in 3 minutes! But it only works for p790 Optimus black. Which sucks because I could get my phone into an inverted S/W upgrade mode (yeah I know it's on the real one) but it only lasted for about 3 minutes then shut down so doing the offline fix just took too long. I would get to about 23% install and the phone would just turn off. . so close! LOL
EDIT: YEAH got the phone to finally work! No exchange now, take that LG! Just kept trying there offline fix

How did you get the flash to work? What error did you get when the phone would turn off? How did you get the inverted S/W mode?
My phone only got to 17-20% before getting an connection error using the offline booth method, this was with both JB and ICS u-boot/boot/recovery .imgs from the P769 ROMs--should I try the steps in unlocking the bootloader to at least get to a bootable state?

How did you solve this? I am at the same steps, I get into mirrored software mode and then I attempt the offline fix. I have even started the offline fix early to save time. And yet it will only stay on for 2 and a half minutes or so and then shuts off. The farthest i have been able to get it to go is 41%. I have tried fastboot mode to try and send boot.img and it just says that it cannot find the boot partition. So it looks like my only option is the offline fix but it doesn't have enough time to complete. I have tried about 20 or so times how many tries did it take for you? Did you do anything special to get it to finish? any advice on how to get it to finish? Spent about 6 hrs last night trying to get this phone back up and running and this is where i am stuck. Its lame cuz i woke up to the phone like this it was fine when i went to bed. And was for months.

Unable to connect to phone in SW mode.

ok, I used pimp my rom and well one little setting in the GPU area caused it to blackscreen.. so I decided to just clear the phone hard reset.. but no luck.
so now im stuck, LG comes up and SW does.. but I can not get the PC to clear the phone it keeps saying usb disconnected please connect.., I was using the Metro PCS rom.. 10D I believe, but anyways anyone that can step me in the right direction would have my gratitude.. ive tried the lelus method.. and just not working right.. maybe its the drivers.. but I made sure all of them are installed..

Leave your phone on while performing the offline flash, don't put it in s/w mode first. Your phone will go into s/w upgrade mode on it's own. Oh and use my modified/hex edited 11th bin

have you check if the kdz is named properly (all caps) eg. V10G_00.kdz
if it's like this v10G_00.kz it will not work.

Plesae left your phone turn on and put it in LG software mode. Then in R&D Flash tool select DIAG mode instead of EMERGENCY. You phone should boot to S/W update mode automatically.

OK. Two options to solve this problem.
1. You can use LG Mobile support tool to recover your phone. Load it from LG website select recover phone from menu.
or
2. Flash ICS u boot & x-loader via fastboot. Please refer to to fastboot tool at http://forum.xda-developers.com/showthread.php?t=2292828 after that your computer should reconize your phone in S/W update mode and you can flash kdz.

I mean in fastboot script by Lelus, there're option to flash ICS u-boot & x-loader. Did you flash it on your phone? Because on JB KDZ flash tool cannot detect our phone. It work fine if our phone have ICS u-boot / x-loader.

How to fix partion problem !

How to fix partion problem !!!
After countlss hours of messing with the LG P769 This is how i got into S/W mode to work !:laugh:
ASSUMING you know how to install fastboot drivers there are instructions on the forum ...so follow those guide note fastboot drivers work best on windows 7 windows 8 was giving me hard time ...
1.install fastboot drivers
2.run lelus script at the same time hold vol+ button once the script shows the OMAP device close the script and immediately put the battery back in .The LG phone will boot into S/W mode !
Make sure you write down your imei or serial number AND make sure battery is fully charged . then
Now simply use the LG software tool or the KDZ offline flasher look around the forum for how to guides
Thats it

Then try enter in lelus fastboot mode, ad then flash x-loader, uloader, boot.img and recovery.img from stock rom for your device type model. Then repeat steps 1 and 2
Where can I find the lelus script?

Sorry for reviving such an old thread, but oh well...
Your procedure doesn't seem to work with my device. Just to make sure we are using the same driver packages, can you post a link to the fastboot driver you have successfully used?
My L9 is always showing this "partition doesn't exist" error message, no matter what I try. Lelus's script seems to do the job and the phone is detected as a fastboot device, and can even be detected in LG Flash Tool (using a 910K cable), but flashing will stop after a little over 2 minutes, because the phone disconnects. During all of my attempts, the screen stays black.
Any hint?

Can you boot into recovery? We now have a custom recovery for locked bootloaders (and CM roms). If you can get into recovery, I would try some adb commands to mount the partitions.
No, no recovery. Just to make sure that I'm not doing it wrong, what is the key combination to boot to recovery?
I have also tried:
Code:
fastboot boot some_recovery_image.img
It says ok, but the phone just hangs at the black screen and becomes undetectable as a fastboot device, until I pull the battery. So, unless the some_recovery_image.img is unsuitable for my P760 (which may be!), there is something seriously wrong I think.
Or maybe I can try the same command with the custom recovery for bootloader locked phones... Where can I find it?

Your EMMC partition is wiped or fried... you really need a JTAG service or a Box like octopus because your L9 is Hard-bricked...
Thanks for your opinion. Yet, I still want to hear from others.
I'm running into more and more problems with the L9 as their me grows.
-Fastboot doesn't work under Windows 8.1 and 10, but under the now obsolete(for me) Windows 7, unlike my other devices, which are fine with Win 10.
-ADB seems to work, but requiring the device to be still able to boot.
-I always boot to recovery from within Android as long as the L9 ain't bricked. After a failed rom install, during which the sd card failed(could no longer write or be formatted afterwards, the last time stamps of files and folders were set during the failed install) I discovered a problem with TWRP(Artas182x's and Edwin's), which may have been present since a long time: Trying to invoke TWRP via keypress will brick the device!
So, if my P760 no longer boots, there's only download mode available, sort of the final line of defense.
-There's sort of a trick if even download mode fails: After a failed attempt unplug phone, force switch-off, if the phone is in brick state. Then switch on, force switch-off again, and only then attempt download mode again. And have patience while holding down the vol button, it might take up to 20 seconds for the phone to switch itself on into download mode. (A single forced powerdown will cause Fastboot NOT to work the next time)
But I'm absolutely clueless about the recovery issue, for now TWRP is semi-working, can only be accessed via Android, as long as the phone is fully working.
W/o Fastboot, I now have flashed stock rom several times and rooted it with Kingo rooter just to be able to run Flashify to install TWRP. If Flashify is the culprit for the TWRP issues, I could need a recommendation for a better working app.

Tried OMAP flasher ? It needs memory configuration file in order to work with our device
No, I didn't. I have sold the phone for spares.
Inviato dal mio LG-D855 utilizzando Tapatalk
I never needed the OMAP drivers and tools. As they are ancient, they will probably make even more problems with newer Windows versions.
I could by no means invoke Fastboot on this device with Windows 8.1 and 10, Seven worked. So you had to go for Download Mode instead to recover to stock rom, then root with the Kingo tool, then install TWRP via Rashr or Flashify, the most time consuming way to recover from the frequent bricks.
And the LG Flash Tool 2014 always needed several attempts to get the job done. The latest official recovery tool from LG works in D/L Mode, but will always download the rom image anew.

Help_bricked my TMobile LG G2 :(

Hi guys. I got the Tmobile LG G2 and it was running on Android 4.4.2 LG G2 D80110c. Then I changed the dpi by editing the build.prop via root explorer up but when the device reboots, it shows system force close and I basically cannot do anything. I realized that my TWRP recovery hadn't installed successfully and also I think download mode is not working. Computer recognizes the device when it is on... Can someone please tell me how to unbrick my device? Is there a way to install TWRP at the current condition of the phone? I think I cannot use lg flashtool because that requires the phone to be in download mode, while mine can't get in download mode...please help! thank you!
Edit: also when I try to hard factory reset the device it shows: ERROR: boot certification error and it gets stuck in black screen.
What I can think of is a way to manually install TWRP via adb or manually flash a kernel that supports custom dpi, but the only problem is that I don't know how to do that...

theres several things you could do.. try srk tools to try and fix twrp, or fix download mode using nuke download.. i dont know how to i just know theres a way to do it.. if other fails and it doesn not go into download mode then you must short circuit the motherboard.... then look at thread g2 hard brick fix..
here but try other first as this one you have to open phone..

also what is nuke download? Thanks in advance.

I don't think my phone is hard bricked. USB debbuging is on and computer recognizes the device when it boots up. I simply don't know how to install twrp via adb commands or alternative methods ... or how to manually flash a custom kernel that would allow normal device boot up when dpi is changed.
