but it just reboot
HOW CAN I DO TO UNLOCK BOOTLOADER
sorry i am bad english
P769
I did it after OTA upgrade to 20b about a year ago (p760), there should be an item in the fastboot menu, no adb required so far, but later, for Recovery and/or superuser app.

I bought a unlocked and rooted AT&T LG Optimus G E970 from ebay. I tried to install CMW/TWRP recovery on it by adb and fastboot commands. When I typed "adb devices" the device model and serial number message showed on PC. But when I typed "adb reboot bootloader" or I manually press Volume+ and power key same time it couldn't be going to fastboot mode anyway. It just going to Android system. What is correct method and how do I do to get it into fastboot mode so that I will able to install recovery package? Is there any way to check bootloader? However, I read some different instrutions online for manually rebooting device to fastboot mode. I don't know what is right instruction for my phone. Thanks a lot!

Unlocked and unlocked bootloader are not the same thing. You can download the Feegee app from the market and then unlock the bootloader and install a recovery all in one go.

Download and flash 20a eu open via offline flash method then wait for 1 hour with sim inside
Then install fastboot drivers on your pc the procedure bit complicated.
Search xda u'll find the procedure to install ti omap fastboot drivers for Optimus L9.
Then follow the unlocking procedure it would work
I have a little isssue with the bootloader...
Sometime ago, i have unlock the bootloader easily, no problems.
But now, i have checked if it is unlocked, and it is no longer
So i have tried to re-unlock it, and fastboot display that's okay and my phone reboot into recovery.
I have rebooted it into bootloader mode, typed "fastboot oem device-info" and nobody is true !
What do you think about this ?
Ps: Sorry for bad english
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.
Thanks for your reply, but it doesn't work
I have only my old recovery (who is twrp in is latest version, no problems with that )
But suddenly i wondere if unlocked bootlooder is useful if i have already an recovery
Finally, i have followed the mega unbrick guide.

So you typed "adb reboot bootloader" in command prompt and it just does a normal reboot?

Yes, then I tried with the keys (Volume - and power) without results
Which version are you currently on I know some of the earlier software did not allow fastboot. With rs988 we had to be on version 11d before we could boot into bootloader
