[Q] What ADB was used to unlock the bootloader? - LG Optimus L9 P760, P765, P768, P769

Hello everyone, as we all know several people have/had problems unlocking the bootloader @dicxz80 might be on to something here.
Please share what Android Debug Bridge version you used to unlock (or tried to unlock) the bootloader with.
I used Android Debug Bridge version 1.0.31
If you don't know how to check, it's easy. Just go to your adb location (with cmd) and type
Code:
adb version
Hopefully this will give us some more information.
I noticed most of the adb(s) I got from L9 forums have "Android Debug Bridge version 1.0.29"
I'm not sure if the ADB version a made difference, but it's worth checking.
Oh and my P769 is unlocked

Specific adb builds do not allow for adb root.... type adb root and see what it says

Right, and this has to do with . . .?
I'm just wondering if the adb version played a role in successfully unlocking the bootloader.
Thanks for the info though.
CM 10.1 P769

Just pointing out differences in various builds. It could be possible that the unlock command needs to be passed in adb shell with su acces on some versions. I don't think its likely though possible.

[Q] Is this root method any different?

1. I'm new here. Xperia Mini is first Android. I really have no idea on what should I do.
2. I've just read trough all replies in
Revolutionary - zergRush local root 2.2/2.3 [22-10: Samsung/SE update]
And I'm wondering, does this way of rooting affect the DRM and TrackID, and all that stuff, as SE site says? I really don't want to lose any functions permanently on my phone, but I want root access, so I can mod small things, and especially install apps like WifiKill.
So, does this root break stuff , as said on SE unlock site?
AFAIK, unlocking the bootloader can erase the DRM keys. Rooting is a different thing. Originally, you could only root after unlocking the bootloader. Apparently this new method can bypass that? But I'm not 100% sure.

Okay, I'm downloading ADB at the moment. Since either it works or can't do any harm, I'm glad to try it.
TrackID works, i don`t use FB so i can not confirm that it works too.
My BL is (re)locked with S1 Tool and the phone was fresh flashed with .335 by wotanclient.
And, yes, by the way, my firmware is 4.0.2.A.0.42 (Android 2.3.4)
And I'm unclear with this:
The binary is available from here: zergRush binary.
The exploit source is available here: Revolutionary GitHub.
Usage:
You will need adb shell to execute this exploit. We need shell permissions.
Push the binary onto /data/local/ and execute these commands in a shell:

1. is binary any different from exploit source? I guess we don't need exploit source at all?
is ADB shell same as ADB? How can I get shell permissions?
why do you not use this script:

Wow, this seems alot easier!
I guess I still need ADB (it needs adb drivers) ?
Wow,running that batch file, I have SU, does this mean it's rooted?

[How-to]Unlock/Re-lock Nexus 10 Bootloader

First Of all Thanks to AndroidCentral for this!!!
I am not responsible for any bricked device
Try at your own risk!!
Now Lets go and unlock the nexus 10!! :laugh:
Requirements"
Fastboot
Android SDK
Downloads:
fastboot (windows): http://cdn.androidcentral.com/sites/androidcentral.com/files/uploads/tools/fastboot-windows.zip
fastboot (mac): http://cdn.androidcentral.com/sites/androidcentral.com/files/uploads/tools/fastboot-mac.zip
Now lets unlock!!!! :highfive:
1.Power off your Nexus 10, and reboot it into fastboot mode by holding the volume up button, volume down button and power button.
2.Plug your tablet into a full speed primary USB port on your computer. If you're using Windows, you'll see the pop-up about drivers being installed and initialized.
3.Open the terminal or command prompt on your computer, and navigate to the folder you have placed the fastboot program in. if you have already done this before you might not get any prob in doing all this stuff!!
4.At the command line, type in (without any quotes) "fastboot devices". You should get a device ID returned, which lets you know that fastboot can see your Nexus 10
5.it is really important to get the ID of the device or else you cannot go further
6.After you have got the ID just type(without qoutes) "fastboot oem unlock" in your command window.
7.Look to your tablet, where you'll have to verify the process. Remember that there's no way to undo the data loss that will happen the instant you say "Yes".
8.When the tablet reboots, you're done. You're free to install custom software, modified boot images, custom recovery.
Enjoy your unlocked nexus 10 !!!
IF you want to RE-lock your bootloader
1.All the steps are same
2.on the 6th step just change the code from "fastboot oem unlock" to "fastboot oem lock" and also flash back to STOCK images (if changed) or else it wont boot
3.This will relock your bootloader so that only authentic, signed images from Google can be flashed to the phone.
Enjoy!!!
Any idea if this sends anything to the google servers? I know when unlocking the T700 it sends the serial to ASUS to void the warranty. Not sure if this was the case with any nexus device or not (also I realize this isnt out yet). Just figured i'd ask if you had any past experience with the N7 or prior nexus device

No, it doesn't send anything to Google, that's why they give you the option to relock the bootloader .
can this be done on linux using fastboot included in sdk?

You will probably need to run fastboot as root, though.

Re-lock
You should also mention in the OP that in order to re-lock you should flash back to STOCK images (if you have changed anything) otherwise the device will no longer boot.

Apologies but is there an online guide? Iv'e got no idea what I did before when I was on my Nexus One, I reckon I might as well delete the SDK and reinstall both SDK and Eclipse sO I can root with a clean system.

It would appear it is a lot simpler now as you can download a sdk / eclipse bundle from here

Why do you say that? I have my Galaxy Nexus locked again with a custom ROM and kernel and it works fine. Ive never seen mention of this non-booting thing if the bootloader is locked when running something custom
I unlocked the bootloader but now the tab will not start? I starts to the X of JB and then nothing happens... Help
---------- Post added at 10:56 PM ---------- Previous post was at 10:18 PM ----------
I have the Solution :good:
If you have the same problem - Go into Stock-Recovery and make a "Factory Reset" then reboot the system.

It's may be wrong, I'm basing it on my XOOM days where it wouldn't boot it you relocked with anything other than stock. If that's different now, feel free to ignore me

I know that when an update comes out I have to relock the bootloader, but if I unlock it after the update does it wipe the device again

Flashing kernel via adb fasboot flash...possible?

Hello, this is a question for the seasoned Linux users.
I have a broken usb x10, with root, unlocked bootloader.
Can I flash Amins kernel via fastboot as following?
open debug on.
adbwireless connected with my pc
go to my adb via android sdk
en type a fastboot command to replace the FXP kernel that i currently have.
Is this possible?
I can't imagine how a broken usb can withhold so many x10 users from flashing a kernel.
No, its not possible, may be you should take a look here :

Thanks bares for the link.

Maybe from terminal emulator,you must root your phone,in terminal emulator type "su" and give it root rights then type reboot oem-unlock.I dont know this will work...
Tried the "su" thing here... normal reboot
would be awesome
yeah wish I could do that, unlocking BL is so much, I only rooted mine.

[Q] Unlocking bootloader questions

I just noticed I have twrp w/o a unlocked boot loader. Will someone help me on what to do? I seen this guide which made no sense and adb I think can unlock my boot loader, but just in case, can you guys tell me what to do so I won't brick my tablet?

Installing TWRP from these forums leverages an exploit that bypasses signatures. Unlocking the bootloader opens advanced recovery capabilities and is (currently) recommended for some of the ROMs under development. However, there are risks to executing the unlock procedure that you need to weigh. A good understanding of each step and how to recover from mistakes is essential. Windows can present an additional challenge as fastboot drivers are notoriously fussy.
If you don't understand the unlock guides that have been posted I suggest you save this for another day. You won't be missing anything unless you just HAVE to be on one of the early CM12 builds.
Hello all. I have had adb working for a while, but fastboot is not recognizing my devices. I am doing fastboot -i 0x1949 devices and it turns up nothing. I have a thor. I am on windows 8.1 64 bit. Any ideas which driver I should install? When I go to device manager in fastboot, I see the Kindle with a caution triangle. Any help would be appreciated.

You can try these drivers (not sure if they will work in win 8.1 though).
