Security error and cant lelus or flash - LG Optimus L9 P760, P765, P768, P769

SO dont know why but i have the security error under logo. NOTHING WORKS.. tried to use lelus to go back to ics but i cant get into the Lg Software mode or whatever to even do adb or abd (spelling)... Even going into S/W Upgrade mode my comp says its not plugged into the phone.. I.. AM... OFFICIALLY STUCK.. i've tried everything and all methods... I cant get into cwm to run a nandroid or nothing... If I get to Mobile Support it just keeps repeating "Connecting to device" over and over again

I have all the necessary drivers installed.... this is getting tough

this is still a problem.. really need help here.... its as if the s/w update or usb drivers arent installed but they are sooooo idk... im stuckk

Hi aarongotgame, did you try with a back USB 2 port (no USB 3), or with another OS (http://revryl.com/2013/08/06/install-unsigned-drivers/) , or another USB cable?
or perhaps with sammyz's LGFlashTool method? http://forum.xda-developers.com/showthread.php?p=52582562
Cheers. Good luck.
Edit: Or this way http://forum.xda-developers.com/showthread.php?p=50729855
** In LG Mobile Support Tool Navigate to Update/Tools and there select upgrade recovery.
Cheers . Good luck.

I have had the same thing by the same procedure to unlock bootloader and flash cwm ... :crying: :crying: :crying: help us
Try this: http://forum.xda-developers.com/showpost.php?p=36688645&postcount=808
PS.: If you can't get your phone in emergency mode (step 5) you can put in download mode instead. To get it in download mode press and hold volume down and up while you connect your usb cable to your pc
the phone does not go into any recovery mode (emergency) indeed, the PC recognizes it as USB\VID_05C6&PID_9008&REV_0000
Yet another brick. There should be a counter for this.
How do I reset the counter?
the samsung is reset with a simple jig... and lg phones?
same problem

same problem ... on l7 ( does anyone unbrick his phone?
Flash the stock firmware

No solution to this problem
I've tried everything.
The phone simply doesn't connect.
USB\VID_05C6&PID_9008&REV_0000
This is what I get when I connect the phone by USB.
I just cant get into emergency, DIAG or emergency CS
KDZ the phone connects and then I get a message afterwards PHONE NOT FOUND.
everytime I install the drivers by LG support tool, it keeps giving me the option to install the driver, like I havent done it a hundred times over.
I think there should be a driver somewhere that can be installed but the only people that have this driver are LG tech's. So they can bill you after
send the phone in cause you rooted it. So the one billion dollar question is witch hero will find a way to unbrick this device. We only need a way
to get a driver to install and we are home free. Or maybe the only other option is throwing the phone for sale on internet for spare parts:cyclops:
HELP PLEASE HELP find a way to unbrick this phone. Believe me I flashed and bricked alot of different phones and there was a way out but in
with this phone it seems impossible!!

And there is no mode to put it in in because te volume buttons don't do crap, the home button also, the only time that the phone does show up is when windows tells me it has an unknown device that I for the love of god can't find a driver for. I tried SDK, the LG drivers, but no dice:crying::crying::crying::crying::crying:

Try reflashing the rom again and use it for some time without trying to unlock the bootloader. First be sure the rom is flashed perfectly and working fine. If everything works ok, you can go ahead with other experiments (of course at your own risk.) By the way, someone was saying Telcel might have not added the bootloader unlock feature in this rom. Just a possibility.
EDIT: The symptom you have mentioned "phone keeps connecting and disconnecting" known behavior (see post 7th point), while installing fastbook mode drivers. Seem your phone has come in fastboot mode (but still locked) and no fastboot drivers yet installed. Installing it is really very tricky. Follow that post carefully.

Which rom you had before? Was it rooted and cwm on? Can you start phone in CWM mode (VolumeUp+Home+Power keys)? If yes, you can flash your cwm backup and be back on your previous rom.
I hope both of you people took nandroid backup (on external sdcard) before flashing.

But can you bring phone in SW upgrade Mode?
I think part of the problem was following the omap4boot. It flashes files to the phone which are not for our phone. I have done the same thing.
When I use the "Phone Tester" app from Play Store, under system info, it says the device is a "U2". This is wrong.
Screenshot here
I dont have any access to fastboot mode anymore as far as i can tell. I cant install clockworkmod on my phone now. Im trying to understand what changed by following the omap4boot guide.

Have patience and do not panic. This phone is really unbrickable, if not physically damaged.
I am not sure what is the status of your phone right now. But keep the fastboot thing aside and give priority to restore phone and make it properly working.
Remove all LG programs from pc, remove all LG drivers from pc and Restart PC. Now install latest LG PC Suite, and put phone in SW Upgrade mode and connect to pc and let all LG drivers install itself.
Do not let windows install any WDM drivers by clicking on this link while drivers are loaded. Do this always for any phone any device you connect to pc. Correct drivers already installed with PC Suite will load quickly.
Now run PC Suite and select Emergency Firmware Recovery option. Now LG PC suite should download fresh ROM and recover your phone.
================
If this fails, keeping phone in SW Upgrade mode, you can still try same with B2CAppClient as shown in 5A part of this thread. Click on "Start Updating"
================
Above both are online method and will need faster internet so rom is downloaded.
In the fastboot thread it clearly says to say no to the prompt that asks you if you want to flash u-boot. If you replaced your u-boot you need to get an original copy of the u-boot for your phone. I think Lelus has a post somewhere, but I don't know if its for your phone specifically. Search for Lelus x&u.
P.S. I've done same thing before and you should definitely be able to enter fastboot and get it sorted out again.
---------- Post added at 05:45 PM ---------- Previous post was at 05:38 PM ----------
I can't seem to find the u-boot x-loader fix Lelus uploaded for someone. You have to look or maybe PM him.

Great. Glad I could help. :highfive:
See, I told you "Have patience and do not panic. This phone is really unbrickable, if not physically damaged. "
I always talk with screenshots Ok, which method it worked? PC Suite or B2C? Which rom it flashed V20A?
You can easily root any locked bootloader JB with Lelus method, if you are familiar to flashing with offline fix. Will be safer+quicker to newbies.

Hi Joseph CZ, perhaps you could try with adb via USB (from SDK tools), I'm not sure, though.

you can try cmahendra sir's 2 in 1 guide or if you can, go service centre, tell them that a update (0TA) showed, AND THEN this is happening. they will.install software for you. as warranty is over, they might charge (5$ here) for software work. I did a hell lot deep **** then you, kept working 6 hours, but wasn't able to fix the phone,went service centre and now typing via same phone.

man service centre, like you have for Nokia, Samsung etc, you can Google LG mobile service centre around your locality,.
doesn't matter it's metro or p778,768,765,760 etc etc etc.
as your warranty is over, you have no fear of them saying warranty void, as ultimately they will charge for the software transaction.
and I know how it feels to see your phone dying on you.
JUST DONT LET THEM KNOW THAT YOU KNOW ABOUT ROOTING /BL/FASTBOOT .act like a dumb and tell them that you were trying to update your software by the wifi (software update OTA) and now this happened.
sweet talks makes way everywhere.

Hi @Aristodikos1, you have an option for installing the drivers in the LG Tool (up- left corner). If the on line tool sees your L9 that's enough, just follow the steps : Update / Tools / Upgrade recovery.

Cheers. Good luck.

[Q] soft brick after downgrading to v10g

Hi all,
Thanks in advance for any help. I originally was attempting to root my phone following this guide here http://forum.xda-developers.com/showthread.php?t=2277639. I was able to use the software update tool several times to flash to V20B and V20D. After a few tries, I read on the authors forum to flash to v10g as I was having some issues (got the CWM L9 Recovery tool installed, and after booting to it, got stuck on encrypting). So I flashed down to v10g. After that, phone wouldn't boot. So have attempted to use the upgrade tool to flash back to V20D or B and have tried following this thread http://forum.xda-developers.com/showthread.php?t=2085344. Even though I can get the S/W Upgrade screen, the software upgrade tool keeps stopping at 15% and tells me the cellphone is not connected. Even though I had gotten it to work before at this same method, I re-installed the drivers and even tried the whole process on a 2nd computer with no luck. I'm guessing the downgrade to v10g is the cause of the issues I'm having, but do not have any idea at this point how to fix it. I have spent hours searching the forums, but have not found a solution yet, so any help or links to posts that could help would be appreciated.
I have the P769.
And if you happen to know why I get stuck on encrypting after using and rebooting from L9 recovery tool, that would be an added bonus. (found it, looks like it was busybox x, will try when I get phone back up).
I have tried on computer running Win 7 64 bit and Win 8 64 bit.
Thanks!

I actually found that post while at work and will be the first thing I try. I also may try fastboot if that does not work. I will report back tonight if it works.

Hi willevans, if you patched your hosts file for the off line kdz flash method, remember to erase the two lines added.
Good luck.

I followed your directions. It seems like we have made progress but am still having issues. It did install some updated drivers, and with the online LG support Tool, seems to find the connection, but stops due to an error at 15%. I also noticed that the screen goes black on my phone and S/W upgrade is no longer displayed. Don't know if there is a timeout were it does this or it is shutting off because of the update process and not coming back on.

I do not see that option. Let me confirm that we are running the B2CAppSetup (LG Mobile Support Tool) and not the UpTestEX_mod2_marwin (R&D Test Tool) program at this point.
Nvm, it looks like with the update, even running the R&D Test Tool, it takes you to the LG Mobile Support tool which will crash if you have it blocked. Same results when not blocked, stops at 15%.

The only options in the LG Mobile Support Tool is: Options and Help in upper right hand corner. Under options is country/language and Upgrade Recovery. On lte left side shows my model once it is connected and gives me greyed out install usb driver option and start upgrade. Those are the only options.Here is an image of what I have.

Still stops at 15%. I have also tried running fastboot. I get about halfway, but when it comes to the part to reconnect to the phone, it just hangs.
Well, using fastboot, I have got the LG tool to now progress past the analysis part and get to the actual update part, but now stops at 15% there. Progress, but am at a loss at what to try at this point.
To sum up, phone will not boot at this point. Can get to S/W upgrade mode on phone. Phone stops at 15% at update portion.
I have tried the offline and online update methods, along with fastboot (get through the entire steps on the computer, but at end screen shows LG logo with fastboot in corner, don't know if this is normal).
I have tried a few more solutions to no success. Luckily, my phone was still under warranty with T-Mobile for about 2 weeks, so sent it in since it wouldn't turn on (unless you did S/W upgrade mode). Hopefully, they wont notice why. Thank you for your suggestions Bojo.

Finally i managed to get the phone in SW upgrade mode, then i tried to flazh the kdz following this tutorial http://forum.gsmhosting.com/vbb/f77...h-any-lg-factory-rom-kdz-offline-fix-1736209/
Everything ok, the program recognize the phone and start to flash, but as before the phone turns of and the process fail.
Considering that the phone stop working after turn it off removing the battery, there is the posibility that the battery or the phone is damaged ?
Hi andr_oid, the link you've provided is just a copy of "our" @cmahendra's link http://forum.xda-developers.com/showthread.php?p=36351786
You could try with other battery, but I think that's not your problem.
