P769 stock tmobile v20f on unlocked bootloder? - LG Optimus L9 P760, P765, P768, P769

I am wondering if there is a way to load the stock rom (tmobile v20f) on the P769 on a unlocked bootloader. I unlocked the bootloader, installed the new cwm and CM 10.2 so far and would like to go back to stock. When I download the v20f cwm recoveries from here and restore my backup from before I unlock the bootloader, I get the mirrored image. Is there anywhere I can download the cwm backups for stock tmobile v20f that I can just restore without losing the bootloader unlock?? Thanks!!

You won't lose the bootloader unlock. There's no way (so far) to re-lock the bootloader. You just need to flash the screen fix. Or just turn off and on the screen every time after reboot, so the screen will fix it self.

I need to know how to get ROM manager to work on my phone so I can boot into recovery and flash backup roms and stuff. How do I install a clockworkmod based recovery manually? Does my bootloader need to be unlocked is there an easier method to unlock bootloaders for lg l9 p769? [/ATTACH]
You can't get CWM recovery with ROM manager,

Didn't work for my rooted P76920d
I'm guessing I have to flash a .kdz that has recovery already on it?
You never really specify which correct busybox you have to have installed anyway, I think that may be it. What busybox do I install? Smart or nonsmart?

Honestly you shouldn't even have ROM manager unless you have an unlocked boot loader and its useless for our phones also if you want to install a recovery without unlocked boot loader try artas bootstrap and if you have unlocked flash the cwm or twrp image

I stopped using ROM manager, it was always useful for other phones but not this one.
At first I installed artas recovery. It didn't work, no flashing LED. Then I installed a different busybox. Now I get LEDs but when I press volume down button it stays stuck in the LG logo and I have to reboot. So I still don't have recovery with artas after switching busyboxes but LEDs flash so that's a start.
I'm just going to try to unlock the bootloader, I need recovery to work.
EDIT: Nevermind, I was using 1.3 version so I deleted the sys files and upgraded to 1.5. fixed, thanks.

[Q] New unlock bootloader method? [P769]

Today had unlocked bootloader, made everything and ended up in V20F with official unlocked bootloader, but, for noob's reazons I can't flash cwm. flashed V20D for root and install recovery for locked bootloader, and there, flashed cwm.zip (http://forum.xda-developers.com/showpost.php?p=44300426&postcount=358) installed succefully, reboot and then it gave me security error. Got into S/W And realized that it wasn't unlocked.
After some researching, found that the unic way to save my phone was by official LgMobile Support, it didn't recoignaized my phone.
Dindn't gave up and tried crazy things, flashed cwm in unofficial fastboot, then p760 JB uboot and x-boot(Lelus fastboot http://forum.xda-developers.com/showthread.php?t=2292828), then I reboot into CWM touch without problem! Thought about getting
unlocked bootloader and flashed CM10.1 Unofficial, and it flashed , reboot and had LG bootscreen inverted, but everything else okay, so I don't know
if this can help to anybody, maybe can be a new method to unlock without making crazy things.
By the way, as you can notice English is not my native languaje, so sorry if I made mistakes.
you forgot this one
http://forum.xda-developers.com/showpost.php?p=44161955&postcount=310
this will fix the inverted lg logo at boot, flash in cwm
all you needed was to flash the u-boot.img for 20f in fastboot, you would have had no security error.

[Q] Bootloader unlock required for TWRP flash?

Hi guys,
So I have an Xperia Z2 running the rooted stock 4.4.4 firmware. I just did a Nandroid backup and am feeling adventurous. My bootloader is locked, as it's possible to root the Z2 without unlocking it. I found out about the CM12 nightly 5.0 ROM and was wondering, if I flash that through TWRP (which I currently have installed), do I have to unlock my bootloader? Or do I not since I'm already this far in without unlocking it? And I'm correct to assume if I restore my Nandroid backup that restores my old ROM right?

hallo guys , i want to know if there is any possibility to install recovery on stock firmware with locked bootloader.

Relocking bootloader

I unlocked bootloader in official method. I flashed twrp and magisk. but after the latest Global beta, I've somehow lost both TWRP and magisk. that said, my phone is no longer rooted and the stock recovery is back. now i want to relock my bootloader. I never installed any custom rom. My question is, how to relock bootloader, and, if i do relock will all my data get wiped? like system reset or something? if so, is there any way to avoid that while relocking?
flash an official miui fastboot rom using mi flashtool and choose the option to clean and lock.
as far as I remember there is an option to keep data but you can backup everything to your PC before flashing
