Hi Joseph CZ, you could try the "upgrade recovery" option.
Cheers. Good luck.

Hi Joseph CZ, here you go:
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.

Hi Joseph CZ, I'm happy to help.
I'm not sure of what you are asking for, do you want to move/copy your files from SD to internal? Can you elaborate it?

Hi Joseph CZ, perhaps you could try with adb via USB (from SDK tools), I'm not sure, though.
I think the easiest way is rooting and moving what you want...

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.
Ill try that

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.
I'm not on my computer right now.

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?

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.

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.

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.

My phone is stuck on the dead android logo with the red triangle. I have no recovery I was on stock rom when it suddenly crashed
I have had my bootloader unlocked but flashed a new kdz in the past.
When I try to flash a new kdz everything on the computer says its successful but my phone boots right back up to the dead android with red triangle. Please help. Also omap4boot does not work for me and adb devices are not detected nor fastboot.
Install drivers again to see your phone on computer.

It turns out I really didn't fix anything, I just got omap4boot to work. What you have to do is install it the second time from device manager after you get pass the part where it asks you those questions with the response of y/n
I was trying to install a custom ROM and did not know I needed an unlocked bootloader, as I used ROMs on a S4 without doing any extra work.
Anyway, so when I attempted that, my Optimus L9 rebooted and gave me the LG logo with the "Security Error" words below it. It's stuck on that now. I tried using the LG Mobile Support Tool, but it gets stuck on downloading new software. The progress bar disappears quickly, so I'm sure it's not downloading.
I tried leaving it to download for around 45 minutes, but it was stuck on the same screen when I came back, with no progress bar. It can't be that it's taking long, I have decent Internet (150/75). I'm afraid of leaving it for hours as the device does heat up.
Is there ANYTHING I can do? I tried calling LG and the woman who was there to help me was rude and treated me like an idiot, only to give me the solution of sending it in. PLEASE help me!!

It's always best to include your device model when asking questions like this. There are four models of the L9 and the all have different quirks.
A factory hard-reset or use the 'Recovery' option in the LG Support tool. Only things I can think of at the moment with a lack of details.
Did you back anything up? If not, not much else to do other than try what I've suggested.
This post may also be of some interest.
Advice::
Never assume anything. Research is your friend I had an LG Optimus One, was easy to mod, root, etc. I bought this L9 ( P769 ) on the assumption that it would be similar. Boy was I wrong. However, I did the research before attempting to do anything with the L9.

I really regret doing what I did :crying:. It's definitely a huge lesson for me.
My model: LG Optimus L9 MS769 (back cover says P769?)
If a factory hard-reset means holding the home button, voIume UP button, and power button, then I already did that but I did not reach the robot.
In the LG support tool, after I enter S/W upgrade mode, it says the software version is V10D and that there is an upgrade available. When I start the upgrade, it goes through the first step but when I get to the second step, it doesn't download I think. I have an image but I can't link to it since I have under 10 posts.

Their network is horribly slow. I've heard of people waiting 2 hours. In addition the tool appears to freeze. However, it's still operating.
I don't prefer this method because of the time.
Learn how to use the unofficial fastboot & offline flash.
Or just keep waiting for that program to finish.

So it's normal? The reason I thought otherwise was because when I searched, I saw 0 people with the stuck/long download issue and figured it was just me. I didn't want to risk my device even further as I am aware that it has been soft-bricked, so there is a little hope available. Should I let it sit for 3-4 hours and let it over-heat?
I attempted the fastboot method but my device was not showing under the Devices section. I do not have a "Other Devices" section when I get to the step.
I am trying the offline flash method now, although I can't find a working V10D KDZ.

Do you see an entry in Device Manager for TI Board ( I think )? It's TI something or other, lol. Sorry brain fart.

I don't understand the device heating up. When attached to PC via USB my P769 is in slow charge mode unlike if attached to a wall charger.

No entry in TI Board or anything similar either .
And I don't understand either. I'm letting it sit on the download process now and it's slowly getting warmer.

At this point you don't have anything else to loose. I honestly can't say yes or no. I think all pertinent partitions will be updated to the newer version. I've never used this method so I cannot say 100%.

As in LG Support Tool? No I don't think it will since your phone has been altered with unofficial methods. I could be wrong tho.
Just realized something else strange, IMHO, my P769 came with Android 4.1.2 ( JellyBean ) and you say you were on stock ICS?
Just out of curiosity was it a WalMart purchase? They're still advertised as having ICS 4.0.4. Last update I got was to from V20G to V20H which is what I'm on now.

I mean that in order for the KDZ flash to work you must do some edits in the host file so that you can do the offline fix, I did it but it won't work as the tool crashes while connecting to the device.
My device also came with 4.1.2. It did not come with ICS. But when I open the support tool it says V10D. I bought my L9 from an official MetroPCS store

UPDATE: I'm trying to use the fastboot method and I think I get why the device isn't showing up. When I initially plug it in (no battery), it appears under Other Devices but then the list refreshes and it disappears. Anything I can do?

Yep. Hurry up and right click on it before it disappears and select "Update Driver". You need to manually point Device Manager to the usb_driver folder in the fastboot tools folder. You may have to do that a couple times. If successful, unplug USB from device wait a couple seconds and plug back in. This will reinstall the drivers just in case they didn't take the first time.

I got fastboot to work!!! I got the inverted screen and all. Now the problem is that I can't flash the phone . I keep trying a KDZ I downloaded. The supporter tool provided in the zip keeps trying to connect to the phone, the UpTest one loads the new Support Tool and it crashes, and the KDZ UPD tool gets stuck on unpacking KDZ and says no phone found.

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.

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.
