Can I flash roms to my L9 with a locked bootloader? - LG Optimus L9 P760, P765, P768, P769

I successfully rooted my L9 and flashed TWRP recovery. I DID NOT unlock the bootloader though. Do i have to unlock the bootloader to start flashing roms? Thx in advance!

I have same question....any response
Thx

Normally, it's needed to unlock the bootloader in order to install roms, but is possible to do it without unlocking the bootloader. Look at my guide: http://forum.xda-developers.com/optimus-l9/general/guide-install-custom-roms-locked-t3249828

I have SE Live With Walman, and it's rooted with doomlord's rootkit, however my phone doesn't allow bootloader unlocking. So, i was wondering if there's any rom that doesn't require unlocked bootloader and costum kernel.

[Q] BL question

I updated to v20f via OTA update first. Then rooted using LGPwn method. Is there a sure way to unlock the bootloader, or no? New to the forum, sorry if posted in the wrong area.
A sure way no, for example: i followed the instructions to unlock bootloader but still its locked
But many people followed and successfully unlocked the BL. The only way to know is try it yourself. At moment im with locked BL and rooted, waiting for a new way to unlock it

[Q] finally unlocked but can i install roms now from cwm installed withlocked bl

but i installed a CWM recovery for locked BL when i had only root and no BL unlocked
i rooted it with some sort chinese program found on these forums
and then installed CWM but bootloader was locked
my question is can i install custom roms with this CWM recovery or do i need to get a new one

I have 2 questions:
1.can i root my lg p768 with locked Bl cause i just wanna tweak it on the stock rom (V20C)
2.if the answer to 1 is yes so what is the difference between having locked or unlocked BL (what are the benefits)

1. Yes.
2. L9 with Unlocked Bootloader can install custom roms and/or kernels
2.5 Unlocking the bootloader is like winning the lottery....lol.

but i also saw a thread called Locked BL recovery installer
so can't i use it to flash CWM and then flash roms?
here is the thread:
http://forum.xda-developers.com/showthread.php?t=2095825
and this thread is what brought me here to ask the same question again:
if i can root my phone and flash recoverry on it without unlocking my BL so why should i unlock it?
Yes you can root your phone with CWM on locked BL but there is no possibilty of changing ROMs in future.

So you mean an unlocked BL gives me the ability to flash roms?

Yes that is correct. However, re-locking the bootloader is currently not possible which means your phone will be out of warranty, so proceed with caution.
