Do the same thing you did before to obtain root, worked for me on LG 4X.

Try to fix promission again.

Root Loss After V20H Update
It's not good for u and I am sorry for u, but on the other side of that coin I'm glad I found this b4 I updated, because I would've been in the EXACT same spot. Good luck on getting out of ur mess!

Also, I was curious if u could use something like Voodoo to keep/restore root after such an update?

Same thing here! The method won't work with the v20h. Any workarounds?

OTA has been stopped. T-Mobile found bugs. Flash the complete KDZ and you should have no problems.
This happens when you disable auto rotation. If you keep auto rotation enabled it will fix the problem. Annoys the hell out of me, wish there was a way to fix it. This isn't an issue with jb though, but I went back to ics because of the jb battery drain

Yes i have auto rotation off thx for the tip. I though jelly bean gave you more battery
Sent from my LG-P769 using xda premium
this is my first LG phone, for flashing KDZ does ones phones needs to be rooted? unlocked bootloaders?. my phone is bone stock.
Battery life has been reported as worse in JB. For me this is true.
You can flash a KDZ on the device in any state. Root or Unlock is not required.
Jason you can flash kdz without root and without bootloader

Thanks guys
I have read alot of thread about jb update. Alot have said better battery life. better response . better stuff. But on some other i read it worsen your battery life. Now when i flash a rom i wait a week before battery settles in. So if i flash jb kdz and find it worse the ics can i flash ics back the same way i flash jb. This would be a downgrade ? Im on p76910g

Lg p769 root help

I am still having problems trying to root can anyone make a video on how to root this. Im tired of ics
Sent from my LG-P769 using xda app-developers app
Trust me, once you get on jb you gunna want ics back.
The battery life is terrible and can't use volume booster or any other equalizer for that matter.
Plus the only difference look wise is little things like signal bar and tickers/switches in settings.
As for apps, same variety except you can get Google Now.
But that's just my opinion

Why are you being lazy, all you have to do is read. I corrected my post on your other thread with the information you needed. Another thing, you should have just replied in your old thread with more details (on the problem you are having) instead of making a new thread.

How are you guys doing this are you using kitchen or android sdk. I am a noob when it comes to this stuff, but I have done a little research. Most of the guides I come across are using custom Roms for the example.

Thank you!!!!!!! This is at least great news after my epic fail with trying to unlock the bootloader of my P769. I can't wait for the themes! Can I recommend Holo? Pleeeeeease....lmao.
Everything runs great except that Goggle Keyboard kept force closing. I fixed it by using ES File Explorer to reinstall it but it happened again when I rebooted. I wound up removing it. Great job, though.

[Q] Unlocking Bootloader on P769

I have been reading up on how to unlock the bootloader on my p769, and I tried this method: http://forum.xda-developers.com/showthread.php?t=2198114. However, when i tired doing the adb command it restarted normally, without unlocking the bootloader. Then, I saw this comment (#45) http://forum.xda-developers.com/showthread.php?t=2474689&page=5. I took out the battery from my L9 and it said "S/W: V10B". Does this mean because it came with ICS out of the box, I can unlock the bootloader? If so, what method do I have to do? This? http://forum.xda-developers.com/showthread.php?t=2277639. This? http://forum.xda-developers.com/showthread.php?t=2198114. Or follow this guy's comment (#46)? http://forum.xda-developers.com/showthread.php?t=2474689&page=5.

I had ICS out of the box, Lady and I are two of the people that everyone knows are unable to unlock the bootloader. ICS out of the box has NOTHING to do with unlocking the bootloader. I can confirm that.

I just discovered that a hard reset while on 20b may cause a semi-lock of the bootloader. What a joke by LG if this is true. We may be locking up the bootloader ourselves with adb reboot oem-unlock!

Well played, LG. So what's the other option?
I'm going to do everything as stated in the video. When I get to the point that the boot screen freezes, I'll just re-flash the kdz. I'll let you know how I do tonight.
That message was intended for P760 users but I'm willing to assume that it applies to all L9 phones.

I'm working on doing this myself. I don't understand..how come it works for some but doesn't others? Everything went smooth for me until the adb reboot oem-unlock command. My phone just rebooted..no unlock screen as saw in the video. I'm not 100% sure but I'm thinking this could be because I didn't have a Sim card in the phone, I only had WiFi. I'm unlocked however and have a At&t compatible net10 Sim I just received. I'm thinking of trying now that I have a Sim card but I had read that some people believe it MUST be a T-Mobile sim which I do not have. Has anyone that just reboots with no unlock after the oem- unlock command been running a T-Mobile Sim card? To me it seems that if these other L9s are able to be unlocked we certainly should be able to as well. I believe its a fine detail we are missing somewhere along the line that allows some while not allowing others. Does anyone have a extra T-Mobile Sim they would be willing to donate to test with or sell very cheap for testing see if maybe it must be a t mobile Sim card. Another thing that came into question was the USB drivers. When I tried to install the ones provided with the bootloader unlock for noobs file I was unable to install them because I already had drivers installed. It stated these were a newer version and needed to be uninstalled to install the ones provided. I did not do this. I just proceeded with the newer drivers I already had installed. Just a few thoughts.

[support] That darn bootloader

Hello.
I know what you are thinking.
Oh no, not another n00b bootloader thread.
Sorry, but sadly it is.
I'm on stock JB 10D MetroPCS MS 769 10d.
I was reading through the Internet, but I'm hard of eyesight and the strain is really starting to stress me. I've never had a phone that seemed harder to unlock(the bootloader). I see many threads and it is really tempting to get a newer rom that will save my battery and all of my troubles.
The only problem is, each tutorial I come across has lead me in a million different directions. Some are dated back from June of this year. I would like an updated method, and of course being the newbie I am, I don't want to try an old method and turn this phone into a paperweight.
I have researched that the T-Mobile ROMs will work on this monstrosity. I know about 2nd init, clockwork mod, have unlocked the bootloader on a tablet. Have been following DROID since Froyo.
I need a sure fire way to do this. I'm sure some of the new guys around here would like a sure fire method.
Let me just brief.
I am familiar with Clockwork mod recovery.
I know basic Terminal Emulator commands.
I run Linux
I know given the right instructions how to Unbrick
My device is currently rooted using the Chinese method, was able to properly install SuperSU and get rid of the Chinese version.
I am aware that the process somehow involves firmware with an inverted screen.
There are so many guides and tools, I've used LG Support tool before, and my final question is...
How the heck do I unlock the bootloader on an MS769 Optimus LG with stock L9 10D firmware?
And yes I've tried the search feature and just got even more confused.
Sent from my LGMS769 using Tapatalk
.lAfter doing some research, I've got everything done up to flashing the 20B firmware this is the point of no return for me. The only thing I haven't done is ADB, but that comes with software mode right before the flash. I'd like to go over this with somebody to see if I have everything set correctly.
Also I need a good copy of the 10D and the European 20B kHz.
... And I'd love to be able to get my paws on the Metro radio... Just in case... For jellybean of course.

Unfortunately there is no simple way to unlock the bootloader, I also have the Metro PCS LGMS769 and managed to unlock the bootloader with a little trial and error and as of the time of this post im running PenberRom5.
Keep in mind that no matter how badly you might screw your phone up, as long as you have a pc and an internet connection you can always restore your phone back to factory settings using the LG Support Tool.

Awesome. Thanks guys. I had trouble with flashing kdz files so I had to go over the tutorials with a fine toothed comb, seems I did not have the small server in the right folder on the root of my C:/ drive. I got 10f flashed, that was my "safe" tester. As long as I can get into software update mode it should be no biggie.
Thanks to you guys as well. Couldn't have asked for better support than on XDA. When I am sure that my internet connection will be reliable, I'll go ahead and follow that guide.
Moving my apps to the SD Card would be really nice. This phone is not very well endowed as far as Internal Storage goes. lol
So yeah to repeat I got KDZ flash working, at least on the "municiple" laptop in the folks house lol. I know what I have to do.
First off, I'm dual booting this old piece of crap laptop I have, it barely runs Windows 7...but it works.
