Use it wisely my friend and once you root and get custom recovery, I would advise you to make a backup before changing anything else!
Good luck!

i mean on flash stock roms,not root and unlock bl.

Any chance to someone build app for restoring l9 ?

Be Careful!!

Hello everybody!!
I want to warn you because of an update for l9!
you can download it but when you install it, it will only boot into recovery and nothing else works anymore!!
all the best

Thank You. Which L9 model is this for?
it is for the lg p760 model
Notice!
To do a FOTA Update, the Phone must use Stock Recovery! But when you have installed CWM there is no Chance for Update. You have to use the KDZ Updater.

How would we get back to stock recovery before FOTA?

I think there is a thread with instructions or we have to flash the kdz file.

i got the same problem as well. The only way to make it work was with recovering the phone and not with the offline method, i was able to use only the normal recovery tool from lg :crying:
I had the problem and i did it with offline kdz flash and sw upgrade mode :laughing:

Using that method would kill root. You would have to root again.

Yes thats right but you can root it again or?

Root?

Can we root Jelly Bean yet for the tmobile variant yet? Like any easy ways preferably....
Sent from my LG-P769 using XDA Premium HD app
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
Hi, can't we root by flashing via cwm? As I have rooted by that method
My phone is l9 jb

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.
Sent from my LG-P769 using xda app-developers app
As I have unlocked bootloader, then flashed cwm using cmd in fastboot mode and rooted using update.zip via recovery

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

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!

You do not need and unlocked bootloader to root. Easiest root in your situation would be the app LGPwn.apk which you can find in this post: http://forum.xda-developers.com/showthread.php?t=2338816
Thanks for your answer ill try tommorow and will report

You could extract it from your kdz. First kdz to bin and fls, then extract the bin to .img files. Grab the recovery.img and have fun

Did you unlock your BL? Which recovery did you install? 2nd init?
Sent from my LG-P760 using xda app-developers app

Try to offline flash/unbrick your phone, by flashing the correct kdz it, or unbrick it with the lg update tool.
