ask for help on unlock bootloader

I have followed all these steps and have redone it twice.

But I can't get "adb reboot oem-unlock" working.

I wait for an hour before I kick the command.

Could you please give me some hints what should I do now?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
I wonder if some devices are rebooting to fast, and are not catching the oem-unlock command. I spoke with someone that tried to unlock and the command did not work, so he had his device replaced. On his new device he is able to issue reboot recovery, but on his previous device, the command would only reboot.

NOTE: IF YOU ISSUE THE COMMAND

(reboot recovery) ON A STOCK RECOVERY, YOUR STOCK RECOVERY WILL PERFORM A HARD/FACTORY RESET!!! You have been warned.

I remember that the root script, back on ice (10e) needed a delay, because some devices were rebooting to fast and didn't catch the command.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
Sorry that will not work, I just looked into it and this is what while happen if you do it.

Or at least I think

SET ADB=c:\l7cwm\adb
%ADB% wait-for-device
%ADB% push emmc_appsboot.bin /data/local/tmp/emmc_appsboot.bin
%ADB% shell su -c "dd if=/data/local/tmp/emmc_appsboot.bin of=/dev/block/mmcblk0p5 bs=4096"
%ADB% reboot

on our device dev/block/mmcblk0p5 is the divxkey partition

I will have to look up the what is the mmcblk0p5 for L7.

Update: that is the bootloader partition for L7, so it will not work. We can't flash that.

Hey, I might have a faster and some what safer way to unlock the bootloader. What about restoring a V20B euro cwm backup, then flash the x & u (for 20B) with a flashable zip. boot up, wait 30 (i would wait way longer) and then issue the adb reboot oem-unlock. Of course I can't test it myself to confirm if it works. It should, because only the x, u, boot, recovery, and system are replaced, the other partitions contain mostly blank data. Plus there will be no need to flash the radio.zip

Adb reboot recovery works fine on my phone. Used the command several times for reset and when I signed cwm with the LG sign tools from the 3d.

Edit... girl just bought same phone. Tonight I will not even boot it straight software flash to open. This will rule out driver conflicts on my window version, adb version issues and more if it works using same exact tools I'm using on this phone. If it don't I will begin issuing unlock command from Ubuntu for both devices.

I installed the L9Recovery.apk after flashing 20b euro. I selected reboot like in the video but the screen stayed black for 10 minutes. I took out the battery and put it back... I used the recovery button combo but it didn't work. I rebooted and noticed the flashing leds like I had before. I pressed the volume down and it took me to the 2nd init recovery.

hmm see if you can do it again but press up and see what happens, remember it took me 3 days doing the same thing over and over and over what i missed? who knows, why it didn't unlock on the first times? don't know.. but it did eventually work again. I kept it simple the SAME over and over i didn't go all out looking for other ways...so what i'm trying to say is maybe keep trying the normal method of flashing 10 then 20 open wait etc iff you get tired of that one then and only then look for other ones, for some reason some get it right away but the ones like me who got them after a few days or tries we keep doing the same procedure over and over.

good luck!

Well I cant unlock the new phone either, what a shocker =-( Im going to have to assume this is bc my service at my house is so bad I cant even register on the tmobile network. I think the sim at least as to be registered on a network, best I get is emergency calls only. Think I will flash the new phone again and carry it with me tomorrow with the new , non activated sim. Then it should activate on the network and I can bring it home and try to unlock it again. This has been my common denominator except for when I flashed the radio on my original phone (I have gotten signal that way very few times). Also to note, the new phone came with 20d from the factory....
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Lol, what do you mean edit the build.prop?

The build.prop is inside the system.img. I'm talk about restoring a 20b euro cwm backup. Then, flashing the x & u (while still in cwm).

The backup already contains the boot, recovery, & system needed.

So if the unlock doesn't work, they will boot back into 2init recovery, restore their cwm backup, and fix the touch screen.

Out of curiosity, I decided to go to the LG support site and chat with a rep.

Rep: I'm sorry. We do not provide information that may void your warranty.

Me: My warranty has already been voided. I'm a customer requesting this. Please help me unlock the bootloader.

Rep: I am only a rep and can speak for LG when I say that information cannot be given. Not to say that it is not possible... you just need to search the internet. It can be unlocked.

I don't recall, I can look at that partition tonight. Took other phone in town with me, still can't unlock it. I requested a few files from someone, I will compare them with mine when I get them. In the code guru thread I though the NV references were to the NV partition. However it appears the bootloader uses nvalues to refer to efuses, exactly how the smartreflex is implemented.

[LG Optimus L9 P760, P765, P768, P769] SomeGuyInOz:
No, that can't be true. When I unlocked mine, I had no cellular radio signal at all, only wifi. That's because, when I flashed to P760 Euro 20b, I didn't bother flashing the P769's radio.zip. So I had no cell signal at all, since the radio in our P769 is not compatible with the P760. I was connected to my wifi network, so the phone did have an active internet connection (I also had the phone and screen set to stay on/not sleep). I don't know if that mattered... Also, note that my SIM card was NOT a T-Mobile SIM. I have noticed a couple of other people were using non-T-Mobile SIMs as well. I doubt that matters, but who knows??

Hey, does anyone know why we are supposed to wait at least 30 minutes before issuing the adb oem-reboot command?? I waited 40 mins, but I don't know why that makes a difference.

Cyanogen Mod 10.1 has made the effort worthwhile and I almost enjoy this phone more than my jailbroken iPhone 5! :p Keep trying, kids!

[LG Optimus L9 P760, P765, P768, P769] asciix:
I tried unlocking using this method, but after trying a week I just gave up. I literally tried everything, like going from 10G -> 20B, factory reset and fastboot erase system before flashing 20B (as you stated to try in the other post), with / without SIM, with / without wifi & data. It just wasn't happening. The only thing I didn't try was fasboot oem format, but I have a feeling that won't work as well.

I am under the impression that this method just doesn't work anymore on phones bought within the past few months.
[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
Agreed, i bought this phone last month.

Notice that these phone's actual model numbers are p769BK, not p769 which could lead as to why they dont work.
[LG Optimus L9 P760, P765, P768, P769] asciix:
Also, thought I'd mention I noticed a strange behavior with this phone. After waiting 30+ minutes and issuing the adb reboot oem-unlock command, and IMMEDIATELY pulling the usb cable from the phone as soon as it turns black, the phone will reboot and display the LG logo. Just about the timing the fastboot should kick in, about 1 or 2 seconds, the phone just shuts down. If you leave the cable in and issue the command, the phone will just continue booting it's normal routine. If you unplug the usb immediately, but issue the command before waiting 30 minutes, the device will just reboot normally.
[LG Optimus L9 P760, P765, P768, P769] MoonMaster345:
The more and more i read things like this, the more i think its because like someone said before, The phone is rebooting too fast.

Maybe we should try to edit the build.prop like it was mentioned before, to slow it down. also we should time the time it takes from an adb reboot on an p769 and a p760 just to see if there are any differences. of course both have to be on the same firmware say v20f or v20h

I only bought my phone about 3 weeks ago, brand new from Best Buy in Costa Mesa, CA.

I bought a SIM unlock code the same day and unlocked the bootloader the next week when I got home to Australia, following instructions in this forum

So I doubt the age of the phone is the problem... It could just be random???

I think it could be easy to miss info because this forum is so big and the info is kind of scattered throughout with random links to other forums and posts, sometimes with outdated files or info. I wish I had recorded and documented my unlocking process properly so that others could see it. I guess I didn't really expect it to work for me first time! I still wonder if some people might be making one tiny mistake, or whether there is actually a slight difference in some hardware...

Lol, about time bro, you have been chilling for a good min. So how long did you wait before issuing the command, and did you flash the radio fix before unlocking?

Did you leave your wifi on? Did you follow the old tutorial more so than the video one?
