Stock recovery for locked bootloader - LG Optimus L9 P760, P765, P768, P769

New l9 (p769) user, I realized there's no point in having cwm if your on a locked bootloader ( can't unlock bootloader one bit, on v20D) and I'm just wondering if anyone had the stock recovery so I can flash the official ota? And no matter what I can't get fastboot to work which I understand has to do with bootloader. Thanks!

Cwm is very useful even if bootloader is locked. Why do you need stock recovery for? Just update ota? And fastboot works with lock bootloaders. If you have an issue just ask me.

It doesn't let me flash the ota? I've been trying and all it does is pretend to flash about halfway and reboots..

Did you modify anything? Build.prop... Or put any mods?

No just flashed the cwm installer and that's it, the stable version. It's rooted and I haven't flashed no zip or anything

So you can't update ota... Hm, just offline flash 20f then.

Can I flash the v20f cwm backups that I saw stickied? Wipe and flash?

Well I'd rather just apply the ota as it is without having to do that since lack of laptop at the moment, is there a way I can get the stock recovery and push it via terminal?
Again thanks for the help!

you don't need to flash anything, just follow http://forum.xda-developers.com/showpost.php?p=40871273&postcount=62

So backing up and installing the 20D backup provided will get me the stock recovery?...confused cause the link you posted was talking about removing cwm, nothing about applying the 20f update. I'm on v20d right now...
Thanks!

Okay, here we go:
1. CWM works with v20D or v20F. If you want to do OTA then you need to follow the link, that Lelus gave you, to the instructions to delete cwm from your phone.
2. If you want to flash the v20F rooted CWM backup that is on the sticky then all you have to do is download it to your sd card then get into cwm and flash the zip file.
3. I would suggest you get cwm working and backup your current ROM before you do anything just in case you run into trouble you can do the "etch-a-sketch" start over by reloading (flashing) your backup.
Good Luck!!!

Ok I deleted all remnants of cwm, renamed the file, and tried to apply the update, still no dice. Can I just restore one of the stock 20f roms stickied using cwm?

Can you accept OTA with root and s-off ?

Noob question. Can you accept the ota with s-off or will it cause issues or possible brick? I haven't had my tbolt very long and it was already modified when I bought it.

You can accept it, but then you will lose root.

If your ROM was developed, ummm, "properly", it should have OTA updating disabled. Of course, not all are...

Yea it has been disabled on the Rom I'm running, I was just curious if it would cause problems if I took the update. I'm still learning the ins and outs of rooting. But I understand what your saying, I've seen some time that the ota push was not disabled.

I believe it will fail at the bootloader stage when it encounters a non-stock recovery.
I'm running stock n all I did was flash stock recovery via boot loader then download n install the ota, then flash cwm recovery via bootloader then flash the su zip then boom rooted ota

Googling stock recovery did nothing for me. I loaded killa sense 3.7, flashed the ota enable zip, but no luck. Error. I guess that elusive stock recovery is needed.

Is your bootloader locked? Do you have a custom recovery installed? You must have a locked bootloader and not have flashed a custom recovery.. In other words bone stock

First things first, must have unlocked bootloader. Second flash recovery.img thru mobile terminal or adb. DO NOT USE L9 Recovery Installer.apk. It will not work. It must be a mirrored recovery, that is a sure fire way to tell you have the right one. Then flash rom thru MIRRORED CWM as well as Gapps and u should be good to go. You can also flash The OC UV zip as well. Good Luck

Root?

Can we root Jelly Bean yet for the tmobile variant yet? Like any easy ways preferably....

Lelus method is the only way currently. A hex-edited bin file for P769 Jellybean was uploaded by cmahendra in his thread. So take a look

Ah I misunderstood the OP I think. I was assuming that he was currently stock and unrooted.
Yeah if you already have CWM you can flash a rooted backup.

Hey friend
You can unlock your bootloader using fastboot method then it will be easier to flash recovery in kernel and if you flashed it successfully then you are done.
As after that rooting is just child play Earlier I have owned other android but I guess LG is the easiest and safest phone to root
Sent from my LG-P765 using Xparent Pink Tapatalk 2
If you don't want to do all the u boot and whatnot then just do the Lelus method with the hex file. It's not too easy but not very hard either. Hmm. . .I wonder if we could use the original root method that we used for 10e? Boys that was easy!
