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.

From a quick glance at the kdz it looks like v20a for p768 doesn't have the code to unlock bootloader.

CRAP!!, i had a bad feeling you'll say that, well i have to dig around and wait til someone other than a noob like me, gives it a shot and nails it, so it can give me a noob-proof tutorial, THANKS mate, keep up the GREAT WORK YOU DO for XDA!
I was wondering how to this.
I was flashing Killjoy's performance scripts (see http://forum.xda-developers.com/showthread.php?t=2411161). After flashing the file and choosing to reboot, for dumb reasons I chose to disable recovery flash when it asked to reboot. Now, when I go to LG setup, once I'm done, I get the message that "lg setup wizard has stopper working" and loops me back to the start of the setup. Please help!:crying:
I know L9 is virtually unbrickable. I just need to be pointed in the right direction and I know I can bring it back!
Edit: Issue resolved!
Did you by any chance uninstall it using titanium backup or similar? Try to get a logcat.

Yea, this is the case. Can't get out of it. I really don't know how in the world did it uninstall itself. I didn't use Titanium Backup at all. After flashing the killjoy zip file, I chose to reboot. I then got a warning:
"ROM may flash stock recovery on boot. Fix? THIS CAN'T BE UNDONE" I then get 3 options to chose from: "No", "Yes - Disable recovery flash, "++Go Back++
I chose yes, and then all went haywire. Is there a way I can determine my phone's connection type via computer? I tried flashing V20D using the KDZ offline method, but it won't progress. It says "Phone not connected." Last I recall, I left the connection on media sync (MTP, I think it's its acronym). Since I'm on JB, I know it needs to be in LG Software Mode.
I have faced this issue too, even if I entered into SW Upgrade mode manually, KDZ did not detect my phone :/
However, I had success using the official LG updater software (connected my phone in SW upgrade mode).

Was your phone recognized by your computer? Because mine isn't. Think you can tell me more or less the steps you took to make it work?
Here's what I've tried so far:
1. downloaded most updated LG drivers
2. downloaded official LG mobile support tool
3. ran it, no effect.
4. downloaded LG pc suite, based on troubleshooting.
5. tried lg mobile support tool again, no good. Said connect PC to internet (???)
6. tried LG mobile support tool from shtttps from offline flash method, no good.
7. Put phone on SW upgrade mode (removed battery, volume up, put battery back in) and retried offline flash method again, halts at 15%. Says that phone isn't connected. It was set on DIAG since it's JB software.
8. Tried recovery update, but phone isn't recognized even if I put IMEI number in.
Thanks!
Flash a ics kdz... should work..

Normal boot to system. LGUP will automatically to boot your phone to Download mode or you can manual enter download mode like the older method.
2- it doesn't have that 2% stuck problem does it ?? coz man that problem is like my nightmare :crying:
- you must use tot firmware to solve it but your data will be lost. or
- if you can enter download mode flash this file https://www.androidfilehost.com/?fid=24052804347825409 via TWRP

Sure. You have to install driver LG before. Depend on your computer for com ports. Not exactly COM41 , you will get another ports number such as COM17,COM20 or COM5.
When you installed dll, it start about 3 sec that is correct.
thx i will give a try at night.

I didn't understand from your post.
I can only open fastboot mode but can't detected by PC and second I open emergency mode.
When I don't do any thing phone boots normally as shown in PC detected all modem and other due i installed all drivers properly but reality is phone sticks at Build : RA - THUNDERG -3.0.6-GNM
So I cannot do access any of above

I was trying to update busybox through just their free apk (available on play store) . so I was installing it I select advance option and also choose non recommend applets . I found after finishing installation my phone was take more time to wake from screen off . I understand that I made a great done .because nothing like this was happened before in stock ROM . I tried to reboot it but stuck at my own added custom animation . as usual I try to go to recovery and delete this animation file . but now I stuck recovery start up text BUILD :RA THUNDER GNM.
God of android come here to help me please
I do not have 250 Rupees to pay them .?
Why can't you use kdz?
I think that you may be able to use it with the bootloader.
Edit: I found out what you need to do.
First, you need to boot to emergency mode.
Instructions are here, it's the same for the Optimus One, so no need to worry.
http://www.ehow.com/how_12314778_boot-emergency-mode-optimus-t.html
Update: Here are more complete instructions.
Make sure you have installed the LG drivers, and you have the kdz file (full image, not just modem).
How to Flashing LG Optimus One back to Original Firmware
Turn off your cellphone
Press and hold Volume[+] + Power + Back buttons, until your Optimus boot in emergency mode
Connect LG Optimus One to PC (via USB)
tips: maybe it`s a little strange to do, but you can try to shake the phone if it can`t detect.
Run KDZ_FW_UPD.exe
Select Type : 3GQCT
Select PhoneMode : DIAG
tips: if this option failed try EMERGENCY or CS_EMERGENCY
At KDZ Files section, select firmware that you already download
Click launch software update button
tips: someone say that it`s good idea to shake your optimus one with gently to avoid stuck.
Wait until it`s done, unplug the usb cable
Press and hold Volume[-] + HOME + Power buttons
See the firmware version, congratulation you did it.
If you don't have the files, I'll post links for you to download them.

Yes, I did so half a year ago, to update my LG Optimus P500H.
Unfortunately there was no update in Israel, and it's firmware was at one of our cellular providers (Pelephone), so I had to use this method to flash a different country's unlocked firmware (some european firmware, I forget which) with the same bands support in the modem, before flashing CM7.1 and TWRP.
It's just been a long time, that's why I didn't remember how to do it.

Although it has not been tested, there is no reason it shouldn't work. The worse that could happen is you're stuck in the same situation.
Firehose exists for g6 now? Would this allow me to safely pry at LG's bootloader without permanent bricks? Would love to take it into my own hands but couldn't afford the risks before. I'm using a Canadian H873

Yep. Have at it. But, like always, I don't recommend purposely bricking.
I should mention that you don't need to use the xml stuff.
In QFIL in one of the top menus, there's a partition option, where it reads the gpt from the phone and you can select them and flash individual files. So you can flash directly bootloader
or whatever you need from your proper kdz source.
Lot's of people have wrecked there partition table trying to unbrick. That is why I included them.

Did you try it yet?
I'm also trying to fix a dead Canadian H873 (Videotron Carrier). Had tried my hand in the past at creating the patch.xml and rawprog0.xml (one method had me peek at the gpt files using an excel/libreoffice spreadheet) but failed for various reason also not having a proper programmer file didn't help any.
For those that encounter issues with either the programmer file failing or getting sahara fail FHLoader, something like cannot find system file try this:
1. Make sure to reboot phone and hit download to phone in QFIL right away. On my device sahara seemed to be timing out quickly.
2. For the second error using the QFIL included with QPST 2.7.474 fixed it.
Sadly i tried to refresh the phone using the backup files i was given with it but now it doesn't get detected. Holding power button the phone vibrates and nothing else happens. Tread lightly.
So good news the programmer file works (tried it on a H873 Videotron variant), bad news do it right the first time or else.
Time to start searching for a way to force it back into edl.

To clarify i used a backup of the files i had on hand for the device and not the files provided by OP.
Hi everyone, I have just bricked my G6, hard brick I think ( does not charge, cant get into download mode, cant hard reset either, only show Qualcomm qloader 9008"). This happened after I tried cross flashing it from LS993 to H872 ( I now know that a NO NO ). Can someone here help me on how to get it back to life ? I ve read quite a lot of different topics but the more I research the more confused I am. Some say I need to restore to stock firmware, but there is no stock firmware for LS993... Any help would be greatly appreciated and I hope you have a very great day
Read my method, download the files, read it again, and follow the steps.

I did but I am still so confused. Can you please tell me which firmware should I download and the firehose to use too. I think I understood most of the post here, except those 2 things: kdz and firehose.
