I have a LG Optimus L9 P769 (T-Mobile). It came with ICS 4.0.4, but did the OTA to get it updated to V20F JB. Shortly after, I found the LGPwn.apk and used that to root. I used Titanium Backup to remove bloatware. I have yet to go any farther with modding.
Ok, before rooting, I connected my phone to my Dell with Windows 7, installed the drivers for all 4 modes available in my phone. I installed LG drivers and PC Suite for the PC. Connection worked perfectly.
As I continued to learn, I installed ADB on my PC. This is when I noticed that my PC no longer recognizes my phone. LG PC Suite can't see it, nor can ADB. My assumption was that it was due to root. So in an attempt to remedy, I used Titanium Backup to put everything back in place that I had removed from the phone. Then went into SuperSu and did full unroot. Rebooted the phone, rebooted the PC. No change.
I uninstalled all LG drivers and LG PC Suite and then reinstalled again. Rebooted phone and PC again. Tried 4 different USB cables. All to no avail. Does anyone have any ideas or suggestions that I could try to get this PC to see my phone again? No rush and not a big deal. I can always re-root...but without ADB, I don't see much hope for much more than that.
(I did search the forums, and to my dismay, didn't find a solution that seemed to help. Doesn't mean there isn't one or I didn't overlook one. Thanks in advance.)
(Also, I have tried this with USB Debugging on and off.)
I managed to get my android back (thanks T3HGOOGL3G33K). I haven't tried to connect to my PC yet. I will update once again when I have had time to test it.
Ok...so I had to do all the work on my PC, save it to my SD card, and then flash using CWM by Artas182x. I uninstalled and reinstalled all LG drivers again and rebooted my PC. Now, the PC is seeing the device, but saying it can't install the drivers for such as MTP, Charge only, Camera, and LG Software. ADB isn't seeing it either when I use "adb\sdk\platform-tools\adb devices". IDK!
I recommended trying another USB port or check the connection. It sounds like the cable isn't connecting to your phone properly.

Thanks @Kuma. I'll try a different port and see if that helps. My goal is just to familiarize myself with adb. (Windows now sees the phone, just doesn't install the drivers. That's why adb can't see it I am assuming.)

@Kuma...I don't know what I did different, but I tried a different cable in a different USB port and to my surprise all drivers loaded right away. Thanks again. I swear I have done this. Maybe I just had to stand on one foot...lol.

Hello fellow android-users. I have a problem. A problem that I can not figure out. My problem is the fact that no matter what I do I can't root my optimus v. I have tried literally everything and still can not root it. On the phone I've tried all known versions of Visionary, Z4root, easyroot, and universal androot. On the computer I've tried SuperOneClick but it always gets stuck on "waiting for device". I have searched so many forums and cannot find a solution. I think I could root it from the computer if it weren't for these bland general drivers I get installed on my computer every time I install drivers then plug my phone into the computer via usb. I have tried plugging it in to 3 different computers and always get these drivers. I have also tried 2 different usb to micro-usb cables (thinking that the one that came with the optimus might be charge only).Down below I have attached the drivers that always come up and what I think I should get (I screenshooted this from a youtube video).And all the lg android,virgin mobile, and usb drivers I have installed in various orders and mixed and matched but still no good. Also I have never had the phone get a usb notification when I plug it in.And yes I have Usb debugging turned on on the optimus. Although I have tried taking it off just for the heck of it.
Thank you for your time and consideration.
P.S. All i want to do is root it so that I can remove the bloatware and overclock it a bit.
Additional Information: Yes this is also posted on android central but I'm posting it here in hopes that maybe you all can help.
Additional Additional Information:I have tried every driver in every combination for the optimus v with never any luck.I have also installed linux on my computer If I will need that.Is there anyway to root it manually from the device itself, because that appears to be the only way. Here is a link to the official thread:forum(dot)androidcentral(dot)com/showthread.php?p=889790
If you try to connect via adb shell, does it successfully get you a "$" or "#"? Or does it say device not found?
This may seem odd, but try turning the phone off and doing the procedure for permanent root. Some have reported that turning the phone off fixes connectivity issues.
i rooted mine 2.2.2 with gingerbreak, very easy, install root and bobs your uncle
Try Gingerbreak..........works all the time
I downloaded the Gingerbreak v.1.2 app and when I press root I get "rooting....... running exploit..... This may take a few minutes! Device will reboot on success!" and I wait and nothing ever happens. And if yall are talking about the gingerbreak exploit on superoneclick I can't even get my computer to recoqnize my phone the right way.I've never had the usb notification thing pop up on the phone.I have downloaded every single driver for the phone and have installed and uninstalled them soooooo many times with no success.And I have had usb debugging on and tried rebooting several times with no luck. All i want to do is gain root acess to remove bloatware and overclock a bit.
Try all 3 versions of gingerbreak
Alright I already tried v.1.2,and 1.1, but it won't hurt to try 1.0.
remove any antivirus tht u have installed and try again
Alright I'll try that and get back to you
I tried it and it made no difference.Thanks for the suggestion though.
your sureshot is to downgrade ur device to froyo2.2. and then perform the root
Did u enable usb debugging mode? oO
josinpaul: My device is already froyo.The optimus v comes with froyo and I have not touched the OS. Also, how I would I do that if no computer can even recognize the device? (Not trying to be a jerk, just wondering if you could change the OS without being connected to the computer.)
ccdreadcc: Yes I have usb debugging on.And yes I have tried rebooting while I had usb debugging on and while it was connected to the computer via usb with no different results.
Keep your memory card unmounted ,I think here is the problem.

If you mean go to settings in the phone and unmount it then I already did that and it didn't make a difference.If you mean don't mount the sdcard when the usb notification comes up on your phone, then I have no choice.I can't get my phone to even get that (the usb notification).It's charge only when I plug it up to my computer and I have installed all of the drivers and tried everything (and yes a million times, I have usb debugging turned on).That's the whole point! I can't get the drivers to recognize the phone.I have tried it on 3 computers with 2 different micro-usb cords with never any success.
I wonder if your phone really is in USB debuging mode despite what it says. Here is a program to verify that you have rooted your phone. Gingerbreak should work on all firmware/android versions. What android version are you on? Many of the methods do not work on 2.2.1 or 2.2.2. If you go to settings/about phone you should see what you are running.
PS When you did Gingerbreak, was the APK installed on the phone or the SD card? Gingerbreak is mentioned in a number of threads. Have you check this thread? http://forum.xda-developers.com/showthread.php?p=13086954
Verify your root with https://market.android.com/details?id=com.joeykrim.rootcheck
I am not rooted.That's what I'm trying to do.I checked my version and it is 2.2.1.And i have always tried running gingerbreak from my phone, but it just says "rooting" forever.
Upgrade to 2.2.2 and give it a shot?
Or jst try after a hard reset o)
How would I upgrade it to 2.2.2 if i can't connect it to my computer?
Anyone have a solution for the ever recurring FOUND NEW HARDWARE?
I'm using windows vista.
already installed drivers for lgp500 but every time i connect the device via usb. my pc wont recognize it. and wont even automatically find the drivers even though i already install all the drivers needed.
Any workarounds?
* I want to change my base band but lgeblahblah wont seem to detect it.
help pls. i want to change my baseband but my pc wont recognize my phone
i had to re-install the lg drivers twice before it started working
one time my sdcard went bad
i assume you have usb debugging turned ON and are hitting "usb connect" when the drivers have updated the phone.
I went with Andy's phoenix rom, he coded in his rom modifications to fix that. Of course Bluetooth still is not working however I use earphones with mic integrated.

if problem is still alive ...
Don't know if you've tried this, but if not:
1.) get LG PC Suite IV for P500, and install it.
2.) connect your phone to PC, and wait
3.) if LGE Modem installed, go to Device Manager, and set it to tilted or disabled.
( sorry, i'm hungarian, and using hungarian windows too, don't know how this option called on english or other language )
After that, if no other drivers was installed for your phone, should be detected, and installed now. Anyway when you update or downgrade firmware using kdz method, flashing will not start until you disable lge modem in device manager, and you will get only errors, so maybe it will help with installing drivers too. Method tried with GW620, GT540 (my last two phones) and P500 too.
I had issues with these drivers the first time I tried using them. I suggest going to LG Mobile Support, getting their software program, it will ask for your phone model and download all the necessary drivers. Don't have your phone connected, it tends to want to upgrade to the LG's latest ROM.
So I have searched everything and and am having a small problem with rooting my phone. The batch file runs and when I select to Restore My Data it initially (on the phone) says Restore Starting... then immediately says Restore Ended with nothing happening to the phone, even after sitting for a few mins. Rooting isn't new to me either I just don't understand why this isn't working properly.
Thanks for any and all help.
Do you have usb debugging enabled and when the phone is plugged in to the computer and you have it on "mtp" mode and not charge only?
Sent from my Optimus G using XDA premium
Yes and yes.
Hmm I had issues the first time with running the bat file for root. I had to use a different computer for it to work. Also when you plugged the phone in while in mtp mode did all the drivers install should have been the drivers.
Sent from my Optimus G using XDA premium
Yea all the drivers were installed properly, I can access everything I need to on the phone from the computer. I'll try it on a different pc and see what happens.
This phone does seen temperamental at times while rooting. If suggest maybe hitting up the IRC for more help. You may be on the new update which will require you to lgpnst to older firmware then root.

Computer wont recognize my device anymore. I have downloaded every set of drivers from this forum, from the samsung website, I even tried downloading kies but it wouldnt recognize it either.
It worked before I did the following and now it doesnt.
First I rooted my phone with route 66 everything was going fine until I made the huge mistake (not knowing) and downloaded rom manager so that I could do a nandroid backup. Well as we all know now, you cant do that. So I got the deadly uellow verizon triangle saying unauthorized software bring it to the store. So I went through the xda forums and found the one that told me how to fix it. I used odin with the alternate restore and got it back up and running. So I wanted to go back and use adams one click unlock and root. I got everything downloaded and ready. I put my phone in developer mode and plugged it in. It starts trying to find the drivers and then it flips from debugger mode to media mode everytime. It starts seeing it as everything but a samsung phone. It says found camera and even cd rom but not the phone. I have read through everything and tried everything I could think of but I am at a loss. PLEASE HELP

Turn off your phone, connect to your computer with the USB cord and turn back on your phone. It should start the drivers and connect to your device.

I tried that, it is still not seeing it like it is supposed to. I was able to get Odin to recognize it so that I could flash the rooted stock again but I can't get Casual Jailbreak to work. I'm not sure if it is because the drivers or not but I am guessing it has something to do with it. Every time I plug it in, it starts searching for drivers and then always switches from usb debugging mode to media mode. The checkmark is still in usb debugging but I don't think it actually is. You can watch it go from device as installer to media.
Are you using the driver install app (zadig i think its called) to install the heimdall driver on top of "gadget serial". Looking at your other post it seems like a driver issue. One thing ive noticed is, if odin can see the device then heimdalll cant and vice/versa. So if odin can see it you have the wrong driver, if you are infact installing the heimdall driver my second question is, does windows xp x64 use driver sig enforcement like win7 x64 does? if so you probably need to disable it. Just throwing my $0.02 out there.
Are you using the official USB cable? I had an aftermarket cable that had worked for months, then decided to quit working. It works with other devices just not the Note2. Changed to my original cable and all is well.

If it sees the device in the dumb verizon cd mode thing and ptp than it can see adb. Its not the cable. however i would try setting the usb debugging first than set it to camera mode. adb should still be able to pick it up
Thank you everyone for your help, I finally got the drivers working and the bootloader unlocked

I have searched (I have 12 tabs open as I type) these forums. I see a few similar cases but I am not finding a solution. I have use CMHENDRA's guides but I am having no luck. (It is my daughters phone so I will give you what information I know) BTW, I contribute in the Note II galleries, I have rooted and flashed HTC One X, Several Nexus 7's, my Note II, Galaxy SII, Galaxy S, HTC Sensations, Nexus 4 and a few older ones. I can currently see all those phones on my laptop. Not the L9.
I believe my son tried to flash CWM for my daughter. She is notoriously rough on phones and he was trying to make sure she was protected. The phone boots into the LG Security Error screen. I can get it to boot into S/W Upgrade mode. I have completed or can complete all the steps to most of the guide. I CANNOT get my Win8.1 laptop or my sons Win7 laptop to recognize the phone to complete any of the guides. B2C, Fastboot, etc. I can see various entries in the Device Manager, I uninstall and reinstall with Driver Signing turned off. I have now reached the point where I have done so many things that I have probably confused myself.
When it did get the security error, the software had been set to USB Debugging and Unknown Sources was allowed. The firmware was 20H. B2C cannot get the phone information (I know it is probably the drivers as is everything else).
Any help, ideas, etc. would be great. I would love to be a hero for my daughter.

I can't get mine to work either. Closest thing I've gotten is using omap4boot-for_optimus-v1.21
its different from some of the others, in that its a blue background and it doesnt actually list the p769. However, after selecting option 5, and following onscreen instructions, I was able to get my front capacitive buttons to light up, but nothing else. I can't enter S/W upgrade mode, I can't get LG recovery tool to recognise my phone, I am absolutely **** out of luck. I dont know if using omap4boot-for_optimus-v1.21 will help or hurt you, but im just explaining my experiences.
Have you installed the omap driver for fastboot?
Thanks for your replies. Windows 8.1 is installing the OMAP driver and when I try to update it, Windows says it has determined that I have the best one installed already or some BS like that. That seems to be the last piece of the puzzle. I am not getting it to use the fastboot commands and when I am in the LG upgrade thing, it cannot connect on the first of the three calls so it says to check the USB cord and connection. ( I have tried 5-6 cords including the OEM cord ).
Thanks again for your help. I will uninstall the OMAP drivers when I get home and see if I can't get the ones I downloaded to install.
I don't have Windows 8.1 so I'm not sure how to address the driver issue. I reer as wel.commend you uninstall the driver, both of them. The one under Android Phone in the device manager and the one called TI Boards in the device manager.
1. Uninstall all OMAP drives (Two of them)
2. Disconnect from the internet (to preventing Windows update from selecting its own driver.
3. Follow steps to fastboot. When connecting your phone have device manager open and right click the device that is flashing on and off (you will see the device manager refreshing and stuffs. It will dissappear after about two seconds but if you get the right click in and the option to install the driver, do it, point to the fastboot driver.
4. Disconnect phone after driver install and pull the battery.
5. Fastboot again, using option 1.
6. Quickly install same driver on the new device in device manager. Be quick.
7. Disconnect, Pull battery
8. Fastboot again
9. Flash ICS U and X
10. Make sure your LG drivers are installed.
11. Reboot PC.
12. Now you should be able to get into SW UPGRADE MODE with the plugging in of the USB
Should not lock up at 15%, make sure you have drivers installed for this.
13. Should work and reboot to home screen automatically.
14. If you really must, fastboot again and install JB U and X
