I sold my s4 clone for $200 just so I could get this email hone after falling in love with it. I feel cheated lol. My bro told me I would have problems unlocking the bootloader If I bought the T-Mobile varient. I thought I did enough research before buying it. I'm thinking alright well I just won't go through T-Mobile. I will go prepaid. Went to Walmart told them I wanted the L9 on Walmart family mobile. (I was in a rush the night I bought it.) Anyways... Did not even realize that Walmart family mobile is through T-Mobile lol. Booooo. I have been so tempted to just break this POS. Then the hubby will feel bad and I can get a new phone haha. Buuuut I can't bring myself to do that. Sucks growing up lol because 5 years ago give or take ;) I would of done EXACTLY that. I'm so over this phone.

It's my thread so I don't care... Don't meet/converse with many people from SC. I'm originally from Aiken, SC. myself. Apparently my daughter is keeping the Carolinas in the blood tho... She lives in NC.

Anyway, for what it's worth, sorry for the headaches received from this device. Looks like LG's gonna lose alot of customers of this phone... Sucks to be them...

I don't think it is only model based the troubles we are having unlocking it, as I have a p760 and I haven't managed to unlock it yet, though I know that [MENTION=1656585]- shifu -[/MENTION] has the same model as me and he did manage to unlock his phone by just issuing the unlock command via adb... I have a Tim p760 by the way...

I think I'm seeing a pattern here. It seems that the TMobile L9's are the ones that are most difficult to unlock the bootloader for. Good ol' TMobile...
[LG Optimus L9 P760, P765, P768, P769] stunts513:
What does T-Mobile have against us making our phones better... I mean this model phone is very difficult to brick from the way I look at it, I got this model because it has very similar hardware to my kindle tablet(almost exactly like the first gen kindle though), and those things are very difficult to hard brick because they show up as an omap device we can reflash the boot loader from if worst comes to worst. Can't see there being a ton of rma's on a device with that kinda durability.

I have no idea what TMobile's issue is. Hell, I'm on a prepaid plan with Simple Mobile. Simple Mobile doesn't care one way or the other. I bought my L9 used also, so I really feel like I should be able to do whatever I want with my device. It's really pissing me off TBH. I actually like this phone, minus the obvious bootloader issues. I've wanted to put my fist thru this damn phone over TMobile so many times it isn't even funny, but it's not the phones fault...

Sick and tired of being told what I can/can't do with stuff that I bought with my money. Money that's literally made by my blood and sweat... Nobody else's...

If that's directed towards me, I haven't been able to do much more research on the subject. There is already a second-init recovery. A Second-init ROM would be implemented in much the same manner.

It would involve some (small) soldering skills - not a problem for me. I dont really understand (google translate again) if a software of any kind is involved :confused:

Wait is that a fastboot cable(otherwise known as a Motorola factory programming cable)? The looked like he was connecting pin 1 to pin 4 in that picture. I'm kinda wondering if anybody has tried a fastboot cable on this device before, I come mainly from the kindle forums, and we always have to use one our devices that are also omap based if we brick it to the point we get stuck at the boot loader, only exception being the 8.9" model that doesn't work with a fastboot cable.

Looks like 100% of tested non-unlockable phones were unlocked! Every phone was flashed with V20C using service cable and octopus box. After flashing the official unlock procedure was applied (Phone on for > 30 min, connected with cable, adb reboot oem-unlock command).

Don't know if that matters but some users indicate that thay were having active internet connection (ie. while youtube was playing a video for 45 minutes they issued unlock command via adb)

[LG Optimus L9 P760, P765, P768, P769] lino08:
Does this mean that you have to flash v20c firmware using this modified cable and the offline fix method and than you will be able to unlock? Or you do need the octopus box?
[LG Optimus L9 P760, P765, P768, P769] Sp4rrow:
V20c was flashed using octopus box and service cable afaik but it is possible to do 'remote flash' but user has to have a phone connected with service cable.

And the P760 doesn't have an encrypted boot loader either. Any P769 model produced from 2013 on has an encrypted bootloader.

And how do you figure LG is not responsible? It's LG's key that is used to encrypt the bootloader as well as the recovery and kernel.

really do think the newer models are unlockable.

I hope someone finds another way to unlock it.

Maybe someone with a unlocked bootloader could backup all the partitions and create a kdz

to use with the offline flash?

It isn't that easy I'm afraid...
[LG Optimus L9 P760, P765, P768, P769] Sp4rrow:
The new unlock way succeeded in all the phones tested. It's simple. The phone MUST be flashed with open v20b or v20c USING Octopus box and service cable. This method somehow overwrites existing bootloader with unlockable one. After that it's possible to unlock phone using old oem-unlock command.

It's possible to remotely flash your phone by someone who has the box. Phone must be connected with service cable.

If you can't unlock your phone just ask at your local gsm service point about flashing phone using this method.
[LG Optimus L9 P760, P765, P768, P769] CoolAAA:
So to find another way to unlock it we would need this.

A.Get a dump from someone who is at the Unlock screen

Or

B.Get the source for our u_boot and modify it to be able to go to bootloader

is this right

I can probably get my cousin to let me unlock his phone and before i unlock i will dump it.

His phone was made before 2013 so i think it will work.

Actually the N5's boot loader can be relocked and you can even reset the tamper flag and of course unroot it.

Also I found this email from Google....

Thank you for contacting Google!

Warranties and RMA are still covered *regardless* if a device was rooted.

We are not trying to prevent customers from unlocking the bootloader and installing a new operating system that allows for "rooting".

Android has always provided customers the ability to do that on Nexus devices, and encouraged other OEMs to do the same. So in that sense we are not against "rooting."

This being said, we can't guarantee full advertised/promised functionality if the source code for the Android OS has been modified as the functionality may have changed.

I doubt this would work on P769 without major porting and unfortunately I am not familiar with LGs (I come from Sony Xperia board). If I could get CM10 based rom that is confirmed working on unlocked P769, I will try to make it work with stock kernel and on locked bootloader. So far I haven't found the suitable JB 4.1.2 rom. Keep in mind all higher roms (10.1, 2 and 11) won't work with JB 4.1.2 stock kernel, because LG hasn't released higher stock kernel for this phone.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
@shinobisoft do you think you can compile CM10 for the p769. I think a 2nd init is the best route. I know the p760 has a device tree but not sure about the 769. I don't have a good enough computer to build from source (plus I still need to learn how, lol). Porting the current 760 CM10 might work, but building from source is a lot better. I'm currently analyzing artas182x work. However I don't have (can't find) the p760 10h boot.img, so I can compare what they did to get it running. Sorry for going off topic.

Something else I've been thinking about is maybe if we modify the ramdisk (via 2ndit) we might be able to mimic the Euro 20B ramdisk. So we won't have to deal with the crazy touchscreen. Not much difference found in the v10E & v20B ramdisk.

Lol I might just make my themed stock a 2nd init. I hate that stock has pushing files directly to the system (with adb) disabled in the default.prop.

Hi guys,

I've just read someone talking about encrypted bootloader.

Now I have a question..

As V20B europe was theoretically supposed to unlock the bootloader in p760. Do you think it is possible to find the key somewhere in its code?

or just to find the encryption command in lastest version in order to remove it and to create a flashable .zip to be installed with cwm?

I guess It's a stupid idea but sometimes easier things are always last things to be checked :)

Yes, but only a limited recovery. The bootloader will still be encrypted and locked and we'll still be using the stock encrypted kernel too. 2nd-init is not a cure for the problem, only a temporary solution.
