i tryed to unlock

well i tryed to unlock with no sucess. i flashed to v20b euro like everyone else. tryed all different kinds of things nothing worked. i have the p769bk. i assume its the new version. the only thing that happend to me when i did the oem unlock command is it would reboot to a black screen. i wonder if anyone else had that same problem with it rebooting to a black screen. i tryed to push up on the volume rocker to see if it would unlock anyway no luck there. i had to hold the power button down for 10 secs then press the power button again to get it to boot back up. so im curious if anyone else had the problem with the booting to black screen. sometimes it would boot to the black screen sometimes it would just reboot normally.

That's exactly what my friend has, I still can't unlock it.

Hmmm....so JB is somehow blocking adb reboot oem-unlock? Even if you downgrade? Wow....that's just messed up!
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
The system re-writes on boot up. I changed a few things concerning the bootloader, fuse, persist files and when I get out and reboot the files are erased and re-written as before. Check the default.prop. It says something about usb for "charge only" so I said to hell with that and I deleted the whole line. Root Explorer did the trick and there was a backup made of the original. when I rebooted the phone and went back to default.prop my changes were changed and it was back to original. I think there is some code in the system files that will automatically write if it sees any changes from original programming. I can't even change anything in /sys/firmware file. . I wanted to add a folder named "fuse" in there. It was creation failed. The system has some fail safes on it and we need to find where they are. AND most likely they will be protected so we need to figure out how to manipulate them as well.

SIDEBAR: IMO that villain guy is a hoax.

Didn't switch carriers but I have an idea. How about somebody host their apns file (from a already unlocked T-Mobile phone) and someone who can't unlock copy it to their phone (after backing it up). If it works we can confirm T-Mobile for blocking the unlock blob.....

Okay, so ive been following the youtube video on how to flash to v20 or whatever, and when i go the normal upgrade test, and choose the country, and when it starts doing the phone update part, it eventually tells me to recharge my phone to continue, and to restart it once its charged.. but my phone is at 100% battery.

Recover fastboot

If you have installed LG official v10I, v10N or some other version that does not have fastboot, you should downgrade using LG Utils and LG Mobile Update. (google for it)

The software checks your battery, at is suppose to not running if you have less then 10% battery. Unfortunately there is some buggy logic and it also reject 100% battery (some how it take 100 % as 0 %). Just let the battery go down a bit then retry.

Okay thank you, I got passed that, but I ran into another problem.. I flashed it, and my phone is all backwards, for some reason when use reboot to recovery app, when it reboots, it just goes into android os.. why is this? I have no internet connection now.. hope everything is okay..

You have to make sure phone is rooted. Install busybox. Install l9 recovery app. Run app. Reboot to recovery. Flash radio zip. Flash touch fix.

[LG Optimus L9 P760, P765, P768, P769] will0899:

Ok your making progress. Download the radio.zip in the op. Flash it. Then download the cwmtouchfix. Flash that and your screen should be fixed, and you should get signal.

there's a "device not recognized" or something like that bubble that pops up and I hear the connection sound when I plug the device in, however the disconnect sounds just about one second after that, so I don't have long enough to go into device manager and check drivers.

dd is linux command to either dump or overwrite a partition. I would recommend overwriting the system.img with dd and then once it's complete, power off the phone (by holding the power button for 10 seconds) then flash(with fastboot) the boot.img & recovery.img (flashing the x&u is not important for the rom to operate). Afterwards perform a hard reset, if it doesn't boot.

You will lose root if you do this, but you can use the old skool binary root method.

NOTE: system.img must be on your sdcard, lol duh

:eek: No way.....

lol yeah. I think I still have an old cwm backup saved somewhere on my system to, that's if I still have a backup of the one I deleted.

ok so I was wondering...

Can't I just restore 20b from cmahendra's thread using the L9 Recovery if I'm already rooted and have it installed? Then just add the bin files to my sd card and try to unlock from terminal emulator without messing with kdz'z and adb from command line?

I have a p769 shipped from metro with 10b. From what I understand I have a decent chance of unlocking it. But since I'm already rooted and have L9 recovery, I thought this might be a quicker way to do it but I'm not sure if it would even work.
