[Q] Unlocking Bootloader on P769 - LG Optimus L9 P760, P765, P768, P769

I have been reading up on how to unlock the bootloader on my p769, and I tried this method: http://forum.xda-developers.com/showthread.php?t=2198114. However, when i tired doing the adb command it restarted normally, without unlocking the bootloader. Then, I saw this comment (#45) http://forum.xda-developers.com/showthread.php?t=2474689&page=5. I took out the battery from my L9 and it said "S/W: V10B". Does this mean because it came with ICS out of the box, I can unlock the bootloader? If so, what method do I have to do? This? http://forum.xda-developers.com/showthread.php?t=2277639. This? http://forum.xda-developers.com/showthread.php?t=2198114. Or follow this guy's comment (#46)? http://forum.xda-developers.com/showthread.php?t=2474689&page=5.

I have ICS out of the box so I'll be trying this out as well later today. Hopefully this method works. Maybe because I'm part of the lucky people who has ICS from the box, I'll be able to get CM10.2.

Chances of ul the bootload has Nothing to do with ICS out of box

Didn't work for me.. I give up.. i just got this phone 2 days ago and im about to sell it..

I'll try again. This time, I'll be using the P760 drivers found here http://www.driverscape.com/download/lg-p760.
I'm also going to install busybox v8.9. I'm going to try flashing the T-Mobile ICS 10G, then 20B to get that out of the way. If it doesn't work, I'll try euro 10G followed by euro 20B.
I'll be doing this tonight and keep you posted.

I had ICS out of the box, Lady and I are two of the people that everyone knows are unable to unlock the bootloader. ICS out of the box has NOTHING to do with unlocking the bootloader. I can confirm that.

I just discovered that a hard reset while on 20b may cause a semi-lock of the bootloader. What a joke by LG if this is true. We may be locking up the bootloader ourselves with adb reboot oem-unlock!

Well played, LG. So what's the other option?

I'm going to do everything as stated in the video. When I get to the point that the boot screen freezes, I'll just re-flash the kdz. I'll let you know how I do tonight.
That message was intended for P760 users but I'm willing to assume that it applies to all L9 phones.

I'm working on doing this myself. I don't understand..how come it works for some but doesn't others? Everything went smooth for me until the adb reboot oem-unlock command. My phone just rebooted..no unlock screen as saw in the video. I'm not 100% sure but I'm thinking this could be because I didn't have a Sim card in the phone, I only had WiFi. I'm unlocked however and have a At&t compatible net10 Sim I just received. I'm thinking of trying now that I have a Sim card but I had read that some people believe it MUST be a T-Mobile sim which I do not have. Has anyone that just reboots with no unlock after the oem- unlock command been running a T-Mobile Sim card? To me it seems that if these other L9s are able to be unlocked we certainly should be able to as well. I believe its a fine detail we are missing somewhere along the line that allows some while not allowing others. Does anyone have a extra T-Mobile Sim they would be willing to donate to test with or sell very cheap for testing see if maybe it must be a t mobile Sim card. Another thing that came into question was the USB drivers. When I tried to install the ones provided with the bootloader unlock for noobs file I was unable to install them because I already had drivers installed. It stated these were a newer version and needed to be uninstalled to install the ones provided. I did not do this. I just proceeded with the newer drivers I already had installed. Just a few thoughts.

Verizon Bootloader

I am about to upgrade my phone, and Im eyeing the Play, however, will the bootloader be unlockable(or bypassable) on the Verizon variant? Since I got a DROID2, that's a must have feature. Any help would be thanked greatly.

People are trying to work on getting the bootloader unlocked, despite SonyEricsson not willing to give any help to the CDMA variant folks (R800x). The document you pointed gives pretty much the universal variant of how to unlock and root for all of the R800 series _EXCEPT R800x_ (which is what Verizon carries). Since you can't unlock the bootloader, you can't currently flash a new/different ROM.
So for now, people are working on it, albeit slowly. Don't expect a unlock/root method in the next day, but it will happen eventually. I know I'm eagerly awaiting it.
I'll work on that too when I get the phone.
I believe Verizon's phones aren't unlockable because Verizon wants total SW control over device.
I'm patiently waiting as well.

It was a leak, we need a new leak from Motorola, this was not a hack at all so we can't just reuse something.
First of all, THANK YOU everyone for taking some time to answer every question. I really appreciate it. I have been reading, and reading for hours...my eyes are starting to bleed.
So... there is NO WAY we can get a better Android than the 2.3.5?
My build number says 4.5.1A_SUN_USC_19.0, that means I cannot unlock the bootloader, isn't it?
Is there another way (hack?) to improve the performance of the cellphone? I have root it, just to change some files I couldn't, e.g. the sound of the camera.
And finally... is it THAT bad being stucked on 2.3.5?

Some people are trying to use kexec, which is a way to bypass the bootloader and install a rom. it will take some time though. I'm not stuck on 2.3.5 so i cant comment on that.

Thank you, I'll search about "kexec".
The reason I was asking if I was stuck on 2.3.5 was regarding to my build number. I don't know how to conclude it's an ota or not.
You can attempt the Pudding Bootloader unlock, it is unlikely to succeed, but it may be possible. You do risk bricking the device though.

Unlocked bootloader
Well, it appears that I am still the only Photon owner around with 2.3.5 and an unlocked bootloader. Unfortunately mine was some sort of freak accident that it happened. I can run run custom recovery and flash all day long. Unfortunately if I install a ROM with any other version (or maybe it's the kernal) it will not work. It will boot up fine but nothing will connect at all. I've tried almost all of them........

[Q] A new software update is available

So this morning the Easter bunny left me a present... My AT&T LGOG says software update available. Does anyone know if the bunny dropped off Jellybeans or just another egg?
I was trying to get a screenshot of the useless message, but the update tried to install and the phone rebooted. Then the firmware update screen reported a failure. After reboot my phone still works on ICS. I'm going to take a backup now and be safe as long as the update doesn't update recovery/bootloader...
Turns out my screenshot worked after all.

I'm on stock & rooted. Not unlocked.
Update notification went off this morning; read some of this thread; told it to let me know again in 8hrs.
Just went off again, I said ok, whatever, told it to update. It rebooted, & now it's just sitting there at the white, "rethink possible" screen.
Key combo reboot actually got it into the "software update" screen, but that then error'd at 1% complete. Error was something like, "01X03fed." It disappeared too quickly while I was typing this. Rebooted again, fully this time, and a, "Installation interrupted" warning is showing.
Hopefully the update notification will be gone, too...

[Q] Messed up while trying to unlock bootloader on P769

Please, I need help!
As the title says, I messed up during the process of flashing. I realized I didn't install the recovery apk and was stuck with an P760 software (V20B) that had a mirrored appearance and a very wacky touch screen. So I tried fixing things by myself. BIG MISTAKE. I've flashed back and forth between softwares, and performed hard resets. I read in another thread how one could fix the wacky screen with flashing v10g. I did so, but my phone remains in the startup screen and doesn't progress any further. What did I do wrong?
So, I then decided to flash back to v20F. Now, I'm consistenly getting error messages such as "sorry the process .com.phone.android/or gapps/or core has stopped working." Something like that. Anyway, the pop-up message is so constant that I can't get out of the phone setup screens because these notification pop up as soon as I dismiss them.
Please help! Not having a phone for vital calls sucks! If there is other information regarding what I did, please ask! I'm a total noob but I recall exactly what I did.
PS: Tried finding that v10g flash thread but search engine is down, at least when I checked a couple of minutes ago.
Did you try the unbrick offline method. There's a couple of threads here just look around...

I am just guessing here. From what I read about LG, they remove fastboot after an update. Since mine shipped with jb, I think I can't get to it because it's been removed.
I could be wrong, though. I'll keep trying but I don't think I'll ever be able to unlock.

[support] That darn bootloader

Hello.
I know what you are thinking.
Oh no, not another n00b bootloader thread.
Sorry, but sadly it is.
I'm on stock JB 10D MetroPCS MS 769 10d.
I was reading through the Internet, but I'm hard of eyesight and the strain is really starting to stress me. I've never had a phone that seemed harder to unlock(the bootloader). I see many threads and it is really tempting to get a newer rom that will save my battery and all of my troubles.
The only problem is, each tutorial I come across has lead me in a million different directions. Some are dated back from June of this year. I would like an updated method, and of course being the newbie I am, I don't want to try an old method and turn this phone into a paperweight.
I have researched that the T-Mobile ROMs will work on this monstrosity. I know about 2nd init, clockwork mod, have unlocked the bootloader on a tablet. Have been following DROID since Froyo.
I need a sure fire way to do this. I'm sure some of the new guys around here would like a sure fire method.
Let me just brief.
I am familiar with Clockwork mod recovery.
I know basic Terminal Emulator commands.
I run Linux
I know given the right instructions how to Unbrick
My device is currently rooted using the Chinese method, was able to properly install SuperSU and get rid of the Chinese version.
I am aware that the process somehow involves firmware with an inverted screen.
There are so many guides and tools, I've used LG Support tool before, and my final question is...
How the heck do I unlock the bootloader on an MS769 Optimus LG with stock L9 10D firmware?
And yes I've tried the search feature and just got even more confused.
Sent from my LGMS769 using Tapatalk
.lAfter doing some research, I've got everything done up to flashing the 20B firmware this is the point of no return for me. The only thing I haven't done is ADB, but that comes with software mode right before the flash. I'd like to go over this with somebody to see if I have everything set correctly.
Also I need a good copy of the 10D and the European 20B kHz.
... And I'd love to be able to get my paws on the Metro radio... Just in case... For jellybean of course.

Unfortunately there is no simple way to unlock the bootloader, I also have the Metro PCS LGMS769 and managed to unlock the bootloader with a little trial and error and as of the time of this post im running PenberRom5.
Keep in mind that no matter how badly you might screw your phone up, as long as you have a pc and an internet connection you can always restore your phone back to factory settings using the LG Support Tool.

Awesome. Thanks guys. I had trouble with flashing kdz files so I had to go over the tutorials with a fine toothed comb, seems I did not have the small server in the right folder on the root of my C:/ drive. I got 10f flashed, that was my "safe" tester. As long as I can get into software update mode it should be no biggie.
Thanks to you guys as well. Couldn't have asked for better support than on XDA. When I am sure that my internet connection will be reliable, I'll go ahead and follow that guide.
Moving my apps to the SD Card would be really nice. This phone is not very well endowed as far as Internal Storage goes. lol
So yeah to repeat I got KDZ flash working, at least on the "municiple" laptop in the folks house lol. I know what I have to do.
First off, I'm dual booting this old piece of crap laptop I have, it barely runs Windows 7...but it works.
