unlocked P768 bootloader before ?! - LG Optimus L9 P760, P765, P768, P769

Hi all,
I did upgrade the 768 to official jellybean (mexico) and has been since trying to unlock bootloader and root but in vain!
all tools or command I use just restart my phone instead of prompting me to press VOL_UP to unlock. I have read about putting phone on (LG mobile/ charge only) and leaving phone running vid on wifi for 30min, but still I get the same result.
So I am here asking if anyone unlocked the 768 before? What exact steps did u do?
Before anyone asks: yes USB debugging is enabled and drivers are installed.
I hope you can help me! thanks!

Telce Mexico LGP768G V20A kdz isn't unlockable. Try Vietnam LGP768 V20A kdz , you definitely should be able to unlock your bootloader on it.

if you wish to root , you do not require unlocked bootloader.

Look amigo, from what i understand you require to unlock the bootloader only if you want to install custom Roms on your phone and as far as I know there are no such custom Roms for our model p768 because of the 8mp camera, además you dont need to unlock the bootloader to succeed rooting your phone.
I have rooted my phone and did not unlocked bootloader, what i done was reading a lot this 2 guides:
http://forum.xda-developers.com/showthread.php?t=2173465 with this one start following instructions from step 0)
http://www.htcmania.com/showthread.php?t=537162 but since your native language is spanish I recomend this one guide better!
Anyhow here is my email [email protected] and if you like you can add me on skype with this email [email protected] I am Mexican and be more than glad to help rooting your phone.
Saludos!

Correct you are amigo, but what i have read is that if you install a custom Rom for p760 on our devices p768 the camera will stop working, so many have tried and cuz of that they went back to stock Rom, do you know if that issue has been solved. ?

Guys, do you anyone that has succeded?, have you read about our devices p768!?, the question remains, what is the point of unlocking bootloader if there are no custom Roms for our devices!!??, I havent read or heard from anyone that they have succeded installing a custom rom witho loosing the camera of the phone, are you willing to sacrifice the camera of your devices!?, there is a way to unlock the booloader of our devices ny the way, it involves going to a stock Rom version that allows BL unlocking and then back the the proper version or the custom Rom , but again and again "8 mp" camera will not work, at least thats what i have read here and there.

T mobile G2

Hi fellas i am new to this forum n wanted to ask a question i even searched fr it but couldnt find the thread
I live in india and have bought imported T mobile G2 frm ebay n it says it is unlocked to work with all sim cards........
so does it mean that it is already rooted and i can directly install mocado roms
or i have to root it again to install htc firmware(the seller said that it has been imported from germany n was unlocked there using some meathod before shipping)
so pls help
pls help
The SIM lock has nothing to do with the "rooted" status of the phone - they are independent of one another.
If you need to root the phone and/or install custom ROMs, follow one of the many guides that are available.

Dave

thx bro n unlock is permanant??or is like iphone?
If you mean the SIM lock, yes if you unlock the phone it remains unlocked.
If you mean rooting (jailbreaking), then the answer is no. If you flash an unrooted ROM, you will lose root access on your phone and have to root again.

so aftr rooting i can also update my phone with official htc firmwares
n how modaco firmware is better thn htc's firmware

[Q] Root for 2.3.3 4.0.A.335

Hi guys,
i've bought the SK17i in Italy and this have the firmware 4.0.A.335 I need a lot root it and a easy tutorial for that (better if is videotutorial) I wait ur answer thanks a lot Tyrigi.
Same here.
there is only one way to root your mini at the moment.
its really complicated and there are no videos about it.
so i guess you should probably wait until there is a easier root solution
you can easily unlock the bootloader for getting rooted. it's not as difficult as you think.

Nice accessory !
Where did you bought it ?
I really miss the old xda....
Hello, i just bought an sk17i mini pro Orange branded. Of course i want to root it and I found a lot of solution, specially one on this board .But finally it doesnt work, my bootloader cant be unlocked because of brand. It's just here :
http://forum.xda-developers.com/showpost.php?p=16659481&postcount=33
I found a 2nd solution on this board again but i don't understand if finally a branded sk17i bootloader can be unlocked or not. Some people say yes, and others no. I want to post a message but it 's in development area so i have to wait 10 messages.....and tis is my first one
http://forum.xda-developers.com/showpost.php?p=18013064&postcount=44
Hy!
I have a same problem... I tried a lot of thing, but... If in your Service Menu it say "Bootloader unlock allowed: No", you can't do anything.
Every method need to boot Fastboot mode. If your phone is branded, and not allowed to unlock bootloader, you cannot start the Fastboot mode... Now.
The Branded SK17i Team waiting for the solution
pls try the s1 tool method. it's a little complicated. but you can do it. and the you will not lose your DRM.
I tried it... I can't enter Fastboot mode.
I think s1tool TP method is only work if your Bootloader unlock allowed: Yes...
tell me exactly what you did to enter into the fastboot mode?
@irumbustalin, do you mean s1tool can unlock branded sk17i?
If not, as soon as Orange unsimlock my phone, will i be able to root it after?
Thanks a lot,
Sorry but UP UP!

[Help] Unlock bootloader in L9 P769

Hello, I know there are tutorials about unlocking the bootloader, but in the case of the P769, is the most difficult of all, so give you some data to see that tutorial or steps should I take to unlock it without problems:
- L9 P760 T-Mobile, 4.1.2 Jelly Bean, V20H (and says that according to LG software, already has the latest version), root and recovery (CWM)
As I said, I have seen many tutorials, but too confusing, and according to what I read, the V20H is an open verison, and not if I can skip the process of installing the kdz V20B (which looks to open the bootloader)
Please I need to unlock the bootloader, confirming what I want most of all if you need to install v20b kdz or not? or at least a simple tutorial for unlocking, thanks.

I hate to bust your bubble but if your P769 ( USA T-Mobile ) was made after March 2013, if memory serves, the bootloader is NOT unlockable. I think the MetroPCS P769 can be unlocked however but don't quote me on that. The only way, if at all possible, is the lengthy process you've already mentioned. For the P769, there is no such thing as a simple tutorial for unlocking the bootloader. Most of the P769 users, myself included, have moved on to other devices because of the inability to unlock the bootloader.
I should also mention that there are tons of threads related to this. Research and XDA's search feature are your friends. XDA prefers it's members to search and search again before creating redundant or duplicate threads.

I understand, I just like to confirm that with the long method (install v20b kdz , wait 30 minutes-1 hour, use the commands in ABD) chance of unlocking the bootloader? O is permanently blocked?
And if it is impossible to unlock, Even I can install roms for phones with locked bootloader?
Now I have understood that it is difficult to unlock in this model, but at least I want to know if there is even a possibility. Thank you

Yes you can flash ROMs for locked bootloaders assuming you have 2nd-init recovery installed.
The chances of unlocking your bootloader are extremely slim at best.
