I used superoneclick and rooted my virgin mobile lg optimus v phone, i havent loaded anything onto it, or changed a thing.
I just want to unroot it....just in case.
please, if someone could help out a foolish newb. it'd be greatly appreciated
That's temporary root. Turn it off and on and you're back to the start.

Temporary?!? I'm curious to know why you said that because I used SuperOneClick to root my phone and it hasn't reverted back. Is SuperOneClick not supposed to be able to root the Optimus V?
u should have used z4root it's even unrootable...!!!!
Hey dude. i tryed to follow the instructions on the forum. didnt work.
watched THIS video on youtube, and it was done fast.
make sure when you click the root button and you open cmd and type adb shell make sure it returns with a # symbol, not a $.
hope this helps.. if you need u can msg me.

Hello, I have a lg optimus l9 p769 runninc ics 4.0.4 its V10g and i need rooting assistance. I have tried many rooting software but none are working. I tried superoneclick, z4root and many more. I recently tried Root With Restore by Bin4ry and i tried both Runme.bat and Runme_L9.bat when i run as an admin, and i press root, it gives me all errors, when i run normally, I get to the part where im supposed to press restore on my phone, and when i press it it says "restoring..." and three seconds it says restore complete and it doesnt reboot or anything.
Unfortunately I'm a super noob at this stuff, I dont need root to flash roms i need it for apps.
If im doing anything wrong please inform me, I read in places that you have to unlock bootloader and stuff but i dont know what or how.
It'd be great if someone could post some steps and guidance.
Thanks

Please read few threads before posting new thread. It is not practical for us to reply every newcomer to ask for reading.
I've already looked at all those forums. I'm not concerned with flashing ROMS. All I need is simple root access and I've tried all the methods yet to no avail. If I can get cwm recovery without root and then flash the root. Zip file it might work but I can't find any forum that explains it.

Also I got really close with root with restore. Only problem was that my phone says Restoring... Then 3 secs later it says restore complete. No reboot no nothing. Any thoughts?

On P769 V10G, You cannot use old rooting method from Bin4ry, it only for some model and version (most 10A, 10B, 10C). You can only root your phone with cmahendra guide. And there are no easy one-click method to rooting our phone for now.
Ok I'll try that method. Thanks

The commands written in your guide won't work. I ran as an administrator but it says 'C:\' isn't a internal or external command, operable program or batch file.

this doesn't always work, but try moving the files to a different drive and replace c:/ with whatever the drive letter is. otherwise, wait till we get jelly bean and use that one click method.
Alright ill try that. Btw do you know when jb will come out for our phone?

I followed cmahendra's guide step by step http://forum.xda-developers.com/show....php?t=2173465 to root my P769.
Ive got a P768e, contracted with star hub singapore. Could someone please tell me which KDZ to use for rooting?
Sent from my LG-P768 using xda app-developers app
you can use the lelus method in this thread http://forum.xda-developers.com/showthread.php?t=2173465
and you can root any rom with this method !!!
The kdz part is confusing
Could you guide me through that?
Sent from my LG-P768 using xda app-developers app
Basically, when you want to root, you first send some files to your phone with ADB, but this isn't the rooting done. you have to reflash the kdz but replacing one of the update files with a modified one. This runs a small script which puts superSU and the binaries in the right place so you then have root access when the kdz flashing is complete. The offline flasher doesn't do anything to your data partition so your only refreshing the system directory.
I think that's how the lelus root method works, I may need to be corrected.
As long as you follow the guide precisely, rooting is easy, it's the prerequisites that put people off I think.

Use the offline kdz method to get back on 10G rooted. Search for lelus' screen fix and apply.
Basically follow links here http://forum.xda-developers.com/showthread.php?t=2198114
Skip the flashing offline kdz of euro 20b, do the rest.

You can also use Smartflashtool and just pick the .fls file. Works without any problem Way faster and easier

Can you elaborate on this? I've tried to use the Smartflashtool to fix this problem and haven't had any luck.
Havent used it in a long time, but in fact you only need smartflashtool (sft), the fls file you extacted from the kdz file and that's basically it. Reboot your phone in download mode and open sft. In there change to the correct tab, choose your fls (dont remember which field, since it is REALLY long ago) hit start and it should update your baseband.

Great idea but how do you get past the magic number does not match issue? If you have the model.dll file for the p769 could you please forward so I can replace the one I have. Mine is for the 940

Like I said, I only inserted the fls file and there was no magic number error.
Maybe check the p970 forum, there is another version of SFT. Maybe it was this one, that worked.
Well that would be great if we could get that to work for our phone because it take like three minutes to flash. This would be an alternate to the offline flash.
P769v20h- 'tis the season to give thanks so push the button already!
Ok again:
It works to flash the BASEBAND ONLY!
It does NOT and I repeat N O T work for the full firmware.
For this to work we would need a new modell.dll, which we probably can only get from LG itself, or a REALLY good reverse engineer here on the forum. But I really doubt anyone wants to do this. I was also talking to xonar_ and he is like an android god to me. He confirmed, that it's very hard, up to impossible to get this to work. I also tested a pack made by him, but it also wouldnt work. If anyone is interested, go ahead an contact him. He is a really nice guy and explains everything very much in detail, if you nicely ask for

Fixed my touch screen on LG P769
I am now able to fix my wonky touch screen finally. Thank God.
After spending the whole day Saturday to unlock the bootloader and install custom rom, I finally gave up after 24 hours. Next I wanted my phone to be in working condition by Sunday night.
I just flashed the stock kdz (V20h) for t-mobile usa. I had this one originally. My display was okay (after initial switch off and on) but touch was still not good.
After that I just did root my phone and installed Super Su. as mentioned in other threads
Then followed the command to cat v6.bin into some firmware file, as mentioned in other threads. It feels so good to get the touch screen working again.
The display is still mirrored when phone boots, but first time i switch off the screen and on again, and it's fixed.
I will edit this post, later with more details and links later.
Also, I did a Factory Data reset, after flashing v20h kdz. But I believe it was not required. In fact, it was very difficult to enter passwords for wifi, google play account etc with the wonky touch screen.
Sounds like you got it under control. Here is a zip file Kuma made that I use when I try to unlock bootloader. Sometimes I have to install it twice but it's the fastest way to get back to normal

Sounds like you made a serious error and didn't do any research before proceeding. Did you install the LG drivers prior to doing anything with the phone? If not, you have just bricked your device. L9RecoveryInstaller.apk is the ONLY way at the moment to successfully install CWM on the P769 if the bootloader is locked. I don't have all the answers myself as I'm fairly new to this device, P769, myself. There may be someone here with a little more insight as to how to fix your issue, but if you didn't install LGs drivers beforehand, I'd say your device is bricked. Sorry.
You'll need to use fastboot to flash ICS u and x. Then go into upgrade mode by holding volume up and plugging the phone to the computer. Upgrade mode should pop up and you're ready to flash any kdz using the offline flash method.

security error should appear when some system mod was been wrong (sorry bad english)
you should re-flash the firmware with kdz(this time flash a firmware with cwm and root included)

L9 P769 is a much different creature than the other P76X variants. CWM CANNOT be installed on the recovery partition unless the bootloader is unlocked. There are very few people here who have managed to unlock the bootloader on this device ( P769 ). Any attempt to modify the bootloader, boot partition, or recovery ends in "LG Security Error". As per my previous post, the only way to get CWM on this device with a locked bootloader is with the L9RecoveryInstaller.apk.

Do you have busybox installed and or do you have multiple copies of busybox installed?
If you don't have busybox, install it from the Play Store. Make sure it installs to /system/xbin.
If you have multiple copies, which I did when I had this error, use the busybox installer to uninstall all copies of busybox and then use the installer to reinstall busybox to /system/xbin.
You may need to run L9RecoveryInstaller again. It will say there is a recovery installed just reinstall anyway.
Reboot and try again.

Cm11 is available, yes some people can unlock the bootloader. Theres a few threads about removing tmobile bloatware, along with solutions to the other questions I answered. Simply search your question and you'll find a solution. THEN if you can't find the solution by searching make a thread to ask about it. Goodluck if you try unlocking the bootloader, its quite a journey!! If you can't unlock it or the process scares you out of trying search Kuma ROM. Goodluck!

Hi, I'm in a similar boat as the OP, successfully rooted the device but didn't realise I needed an unlocked bootloader to flash a recovery. Now I get Security Error.
Now, I keep seeing "ICS x and u" on this forum, and have no idea what it is. Yet people keep saying it like it's obvious.
Is this it? http://forum.xda-developers.com/showpost.php?p=44144663
If so, obviously I can't follow the steps because my phone won't boot up past the splash screen. And said phone isn't recognized by ADB at the moment, because I can only figure out how to boot it into S/W update mode.
Currently I can't even use the L9RecoveryInstaller.apk, because, again, can't boot up. Help?
