Hi. I have a problem with my p760. After update of CyanogenMod i get "security error", so i used LGModbileSuppeor to recover it. Now everything works fine except I can't install CWM because I'm getting security error again.
I'm installing CWM via Omap4Boot because I can't get into fastboot via reboot oem-unock. Is there any way to install CWM again ?
No you cannot install CWM from fastboot since your bootloader is locked. First unlock your bootloader, try V20b europe open kdz. It works best for unlocking bootloader.

The problem is that my bootloader is unlocked and I'm geting Security error
EDIT:
I tried to install recevery again. Of course i get "Security error". So i decided to install ics xloader and uboot then v20h europe open via kdz. When i finished my bootloader status changed to locked, so i have to find a way to unlock it again.

Hi,
I flashed V20D on my P768 after recovering from some weird other problems(hidden message below). Now whenever i try to flash recovery using fastboot or flashify, i end up with a security error. I have to flash the stock recovery to make it normal again. (backed up using flashify)
Hi,
My p768 has an unlocked bootloader. I was running CM10 on my device. I tried to install MIUI from this http://en.miui.com/download-197.html .
Once the installation finished, my phone got stuck at the LG logo. I couldn't enter recovery. I tried to flash recovery again using fastboot. I did that, but ended up with the security error. Then I tried http://forum.xda-developers.com/showthread.php?t=2585161 this method. After i flash the uboot, boot and recovery, my phone is unable to go to the sw upgrade mode. The lg logo comes, but the distorts into different colours, or some white lines come up, and i am unable to do anythng with it. This is what is happening--

Could anybody please help me out with this?
Any help would be appreciated.
EDIT--
I managed to get it working using online upgrade.
The phone has a 20D firmware.
The problem now is that I can't install recovery. If i flash any recovery using fastboot, the phone boots up properly, but if I try to go into the recovery mode, i get the security error. And then it stays. To recover, I have to go to fastboot mode and push in the recovery being used here 'http://forum.xda-developers.com/showthread.php?t=2585161'
I also tried CMahendra's latest way to root the device and install a recovery (http://forum.xda-developers.com/showthread.php?t=2779985). Even this led to the same security error thing.
I am trying to flash a different KDZ, but once i press the button to start the upgrade, the software crashes. Also, I have a new version of the LG tool.
EDIT--
I was doing the shttps thing wrong
But now i have a different problem. Whenever I flash recovery, I end up with a security error.
Flash ics u-boot and x-loader in fastboot and again you will be able to go into s/w mode.

Hello,
I tried to unlock bootloader of LG L9 P760 using this guide:
http://forum.xda-developers.com/showthread.php?t=2221102
but I didn't succeed.
I tried this method while having V20i rom, then I flashed V20B EUROPE OPEN and tried once again, still without the results.
I even managed to root the phone using this method:
http://forum.xda-developers.com/showthread.php?t=2439667
but entering "reboot oem-unlock" command in terminal emulator didn't make any results either.
The phone just normally rebooted every time.
Is there anything else I can try to unlock bootloader? I'd really like to install Cyanogenmod on this phone.

So based off of what you have said:
-Your bootloader is still locked (you haven't said 100% for sure that you are unlocked)
-You may or may not be rooted as well (again, you haven't said if you are or are not)
-You want to run stock recovery, which is the recovery that Moto ships with the device, which is entirely useless for custom ROM flashing
This is the guide you need to root and unlock http://forum.xda-developers.com/showthread.php?t=1302423

Keep going with the guide. Go to the fastboot oem unlock step and go from there

Hey, it's works, now i just flashed cwm. and everything looks fine. Thank you for your help.
Like the title says. I am rooted and have insatlled RR MM and TWRP is also installed. I am able to do stuff from TWRP.
But when I check bootloader status from fastboot, I see it's locked.
I had unlocked the bootloader UNOFFICIALLY.
How do I unlock it again? The unlock command gives me Invalid token error.

Go with official unlock. It takes a few days from the request, and you won't have any problem
Hi!
What happens if you don't have permission to unlock bootloader and you still try to do it using fastboot oem unlock on Xiaomi Phones?
I have already got the permission and I've rooted my phone, so I didn't really try it because I was simply afraid. Has anybody tested that?
Also, if I relock my bootloader again using fastboot oem lock, will I be able to unlock it using fastboot oem unlock or will I have to use MI tool?
Aaaand the last question - I haven't installed custom rom or TWRP - I booted TWRP using fastboot boot xxx.img, then installed SuperSU package. Is it dangerous to lock bootloader with phone rooted? Recovery is still stock, so ....
