Hey everybody, first post. Anywho, I rooted my phone on version 4.0.4 and I used the lelus method, and once I got the phone to root everything was fine. I wanted to update to jb so I went into busybox or superuser, and unrooted and it gave me an error, and of course I don't remember the error. My root access is gone but things that were in the root like a custom boot animation are still there, i'm not sure if thats normal but now when I try to update to V20f and get an exclamatory android and a reboot. I already tried a factory reset and hard reset but I still can't update. Thanks!
Have you tried using the lg support tool? Thats how i updated without wiping everything. After that tuns, ifyou are trying to still have root, run lgpwn.apk,and lg-recovery-installer.apk. works like a charm

I woke up this morning with an OTA update on my P769 USA version. I have not ever rooted my phone yet and have been waiting it out for some roms to come out and clockwork mod. My phone has the 10e firmware that can be hacked to unlock the boot loader. My problem is my phone downloaded a new OTA update, 10g. If I reboot my phone its going to install the update and I'll be screwed out of being able to root the phone when I want to (locked boot loader). How do I keep this update from trying to apply itself on reboot? I don't have root access. Can it be rooted w/o having to reboot to thwart this update? Can I delete the update file? I'm really trying to avoid having to reboot the phone now. (The system update apply/reboot pop up is driving me nuts!) I never agreed for this update to download! WTF?!

The update will not automatically install when you reboot. Root your device using the many instructions in this sub-forum. Use the search.
No it won't but u can root ur phone. All L9 models can be rooted
Or you can just update himself(optimus L9) and flash it back to the rootable roms using KDZ offline flash
Or start phone in CWM mode, take nandroid backup and reflash V10E, root it and restore V10G nandroid backup.
Dont know if this work perfectly or not, but just suggesting.
PS: I just wonder what Update it would be after V10G? Is it JB for P769?
Or you can let two month old topics stay dead.

Two potentially useful posts in an old thread goes a much longer way than some snappy quip posted almost solely for thanks.
Oh, look. I'm being about as useful as you right now. Time to go outside.
Thread Closed, OP if you wish to reopen, just send a PM. Thank You.
ok, so im not a total newb when it comes to rooting but here is my question(s).
recently got the jellybean update on my t-mobile l9 and was wondering the simplest way to root it?
do i have to unlock the boot loader to root it??
all i really want to do is be able to remove some of the t-mobile bloatware.
please and thank you to all who help.
also ive briefly glanced at Lelus root/offline flashing method, is all that work needed to simply root the device??
if so, could someone link me to the EXACT files i would need, not the "look in this thread for your version"
(if i break the wifes phone, or lose here saved games, she will kick my butt lol)
my device is the following
tmobile
lg l9
p76920d
android version 4.1.2
I second this motion! And no one mentioned is the lelus root method will work with V20D

Lol, yes all of that is needed to root the device and as of right now, you have to have root before upgrading to jelly bean. So if you really wanted to root her device. you would have to flash 10g (ice cream) for her device (p769).
If all you want is to disable some bloatware trying going to apps in system setting and see if you can disable it.

You would need to downgrade to V10G using the Lelus method (which isnt hard at all just follow the directions carefully) and then root the phone. After that you could update to a rooted version of V20D ad then you would be set.Everything you need is in the Development forum.
i agree with grey use the V10G Method then use the CWM BackUp with radio flash through CWM Recovery by artas182x always remember to make a backup of data from your backup app and as well backup your sd card to the computer and please give thanks to the devs they have helped us alot in this development section and they deserve the credit if i have helped you can always give me thanks but the real credit goes to the devs and people that help our glorious community

I'm on p769 10g rooted and everything works. No CWM installed. Don't want to brick or damage it. Suddenly started getting system update messages but can't update because i need root. Is this the link for me to follow if i want to upgrade and root JB Root?

Just install voodoo OTA rootkeeper and open and press protect root. After that you can safely take OTA. Also if OTA fails you're not bricked, pull battery and it will boot back into ICS. The reason we can't directly root 20D is because we don't yet have the KDZ file from LG.

I protected root in voodoo, sys update restarted the phone, red triangle/some kind of error and then phone restarted by itself back to normal.
I wish they come on the bloat is so massive

Then you have 2 options to go from here (or 3? I guess). Either use the offline flasher to flash 10g again(use the lelus root method so you don't lose root.) this should make everything default and OTA should go thru. Afterwards don't forget to do voodoo again. Or install CWM and update with one of the clean rooted backups available. @artas182x CWM for locked bootloader works great. I know you said you don't wanna mess around with CWM but there is very little risk involved, just be sure to backup your current rom first. If you backup all your apps and app data in titanium beforehand you can restore them back to the clean JB after all is said and done. I'd personally go the CWM route as it is much faster.

i'm on 10g rooted with voodoo now. Flash 10g again?
CWM i didn't install because wasn't sure if 100% working or still buggy for p769. CWM is a better option. Backup is not critical. I had trouble restoring with titanium before so i don't mind reinstalling apps. Updating to JB is not critical either unless it brings some improvement in speed/ram management. Update notification was incessantly bugging me every 5 minutes that's why i wanted to get rid of it but its no longer a problem. Disappeared. Will i be able to CWM a rooted/unlocked bl JB for p769 eventually or should i do the rooted JB now and wait until bl can be unlocked in the future? Or, possibly new rooted unlocked bl roms in the future?
I have P769 20D ( locked BL ) rooted by KDZ method long time ago. Now, I wanna update to 20F OTA. I installed rootkeeper, downloaded the OTA then restarted the phone . The phone showed the Android logo, updated for around 25% bar and showed the red triangular ! .
1) Is there anyway to complete the update ?
2) As for unlocking the BL, is there also any better method for P769 recently beside the wonky and mirrored touchscreen one ?
Thanks
1) OTA update requires no CWM, all boatware in place (basicly the system image has no change at all) to work. Chances are you did some thing to existing system partition so OTA fails. The easy way for you to update is to flash KDZ again. Better now you can update to 20H directly instead of 20F.
2) No, not yet.
Easiest thing is to flash this in cwm.

OK where to start... Have a P769 T-Moble v 20f. I rooted it previously with LGPwn.apk. Still had locked bootloader. I was trying to switch the storage and somehow screwed that up to where my phone would only say encrypting reset phone. Flashed with a rooted recovery from a post I found here and got my phone working again, but I have no root now and LGPwn.apk doesn't seem to work for me. any ideas or help would be awesome. I do have CWM and it still apparently works.
Kinda a noob so bare with me lol.
I just bought a lg l9 p769 and after a quick search on how to root without a computer, I used lgpwn.apk and installed supersu and all was well intill my gf did the OTA update to 20H. Now no matter how many times i run lgpwn and repeat the process it wont root! When i launch lgpwn.apk it says "lgpwn has been denied superuser permissions" ive uninstalled everything multiple times and factory data reset, and still nothing!! Plz help
Still no luck on rooting again with the 20H OTA updat.e a real headache especially since i dont own a laptop
