A lot of people are asking which recovery they need to install with the un-locked bootloader.
This is compatible with all L9 variants that have unlocked bootloaders.
Here is the original link.
https://plus.google.com/app/basic/stream/z13pxhrrjv3sjtoe423wjzkagyveej4wa04
I have attached the image.
Here are the instructions:
1.) Follow instructions in first post from this thread: http://forum.xda-developers.com/showthread.php?t=2119090
2.) Flash CWM with this command: `fastboot flash recovery recovery-clockwork-6.0.2.9-p760.img`

3.) Pull battery and re-install.
4.) press "Vol-Up + Home + Power" till recovery is loaded.

Unlocking the LG Optimus L9
The L9's (p760) update to Jellybean from LG started rolling out today. It has a ton of new stuff for people who are interested in keeping the stock ROM,
and another new thing that's of interest to us: the bootloader is now unlockable.
How?
Step 1 - After installing the JB update (I don't know if there are any leaks, but it so avoid them. The real update is out),
make sure you have a SIM in your phone and let it stay on for at least 30 continuous minutes. This is important!.
If you skip this step, you may end up with a permanently locked device.
Step 2 - Enable USB debugging in the developer options, and run " adb reboot oem-unlock " from your PC.
Step 3 - You'll land at a confirmation screen like the one in the first photo of this post. Read it, and follow the instructions there.
Step 4 - If your device unlocked, you'll be in fastboot mode. The phone will helpfully tell you about it (Second photo). Congratulations,
your bootloader is unlocked and your L9 can run unsigned boot images.
Step 5 (optional) - While you're at it, stay in fastboot mode and flash CWM from http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.2.9-p760.img
with " fastboot flash recovery recovery-clockwork-6.0.2.9-p760.img "

You should be able to flash it over stock recovery. Don't flash the recovery for locked bootlaoder. I don't think it works when bootloader is unlocked.
After flashing pull battery and re-install. Press "Vol-Up + Home + Power" till recovery is loaded.
So I unlocked my blog and I am trying to flash recovery I use prada I got the point where it says put the battery in after 5 seconds then it says pull sub cable and plug in when I get LG screen. I get mirror image of LG with fast-food ov in the corner I. At this point I try to flash recovery but when try to boot to recognize very it's not working am I missing something here.
I flashed 20b unlocked bl flashed back to 10g rooted fixed touch screen stuck on trying to install recovery

[2in1GUIDE][JB] Unlock Bootloader and FASTER Root L9 Method
I personally used the touch cwm image in cmahendra's guide. Works well, im still mirrored.
If you have unlocked bootloader and root ( that's a must) it is much easier to use Nandroid Manager (free from market) to flash any compatibile recovery image (6.0.3.1 is the newest touch version or non-touch) just from the phone from *.img file . I've tested it took 2-3 min .
i installed all the fastboot drivers ..still when my phone is in fastboot mode ..it simply doesnt recognize the device..it shows a error stating the usb device attached has malfunctioned and doesnt recognizes it. :crying: I have installed android sdk ....please help searched in google and running out of option ...guys help me out....i really want to root my first and the best android phone again :crying:
does it work...
which model no. do u have..
will it work for p765 v20a

My phone is only restart system after adb reboot oem-unlock .... what I do wrong ?
after installing the recovery, how do I access it? is there any specific "turn on" + KEY combination?

Easiest way is to pass adb command from command prompt. ADB reboot recovery or you can use ROM manager to boot into recovery. If you absolutely need to boot with key combo. Hold vol up + home button and power button when phone vibrates release power it should boot into recovery

fastboot is not just for unlocking your bootloader. fastboot will allow you to flash almost every partition on your device, especially now that your bootloader is unlocked. Flash CWM with fastboot. Then you can use CWM to install CM, AOKP, AOSP roms that are already rooted. Don't know how many there are for your device tho. There's all kinds of information around here for using fastboot. Search is your friend

Theoretically yes. If you have a Terminal Emulator app on your device, type the following two lines. Each line is a separate command.
Code:
su
reboot fastboot
That should put you in fastboot mode, then allowing the fastboot executable on your system to communicate with the device via the fastboot protocol. The 'su' may not be necessary.
Otherwise you'll have to use adb. Make sure device is booted normally. Doesn't matter what mode it's in, ie; Charge Only, MTP, LG Software, etc... Type the following in a command prompt window...
Code:
adb reboot fastboot
If you don't have ADB installed, you don't need the entire Android SDK, just the platform tools. There are several packages floating around here that contain just the fastboot executable and the adb executable with it's support libraries. Support libraries are for Windows only.
Somehow, trying to install TWRP via fastboot, I've soft bricked myself.
I can boot into fastboot mode and that's about it. My bootloader says it's still locked even though I've attempted to unlock it via the fastboot oem unlock command.
So I'm kinda stuck at the fastboot mode screen or the 1+ screen.
Any idea's?
I'm soft bricked too.
Unrooted using KingRoot and then tried to install the 2.1.3 update.
It failed and now I can't get into the system. What should I do? Can I unlock my bootloader in this state?
Try fastboot boot ( name of twrp recovery file).img

Yep, can get into fastboot. Should I first just boot TWRP using fastboot boot, and then
1. Wipe system, 2. Install OTAs?
Edit: Unable to fastboot boot, says Device not unlocked
Edit 2: fastboot oem unlock works! Let's try flashing recovery.
The following procedure will only work if you have a microSD card with adapter for a computer. You need to download the stock rom and save it to the microSD card then place it back into the X.
Ok guys, you should still have stock recovery if twrp didn't flash. Go to this thread http://forum.xda-developers.com/showthread.php?t=3244996
Click the link to download otas, only download the one with this file name ( OnePlusOxygen_14_OTA_003_all_201510241934 ). You can flash this file through stock recovery. It should preserve your data. I personally did this while I still had a locked bootloader.
If you can't do this now, just turn the phone off and leave it charging for a while. Then just try to turn it on, or try to get into recovery.

Sorry for bothering you, I managed to unlock my bootloader and flash recovery. I'll flash stock OTAs now and it should boot up fine.
Thank you so much for your time
How did you manage to unlock your bootloader? I cannot even get into stock recovery...It's either fastboot or nothing!

Bad news. You'll need to do a remote support session with OnePlus to have your phone reflashed with their Qualcomm tool.
Sorry for OT, didn't want to create another thread!
Here's what I did
1. Unlocked the bootloader
2. Flashed eng.stk TWRP recovery
3. Flashed OxygenOS 2.1 OTA 003
4. Flashed OxygenOS 2.1.3 OTA 004 + OTA 005
5. Rooted using SuperSU
6. Installed eng.stk blu_spark kernel
SOMEHOW, I still have my modem and IMEI partitions!
Does that mean I just need to
1. Flash stock ROM
2. Relock bootloader
To reclaim warranty?
Edit: I wiped /system before flashing OxygenOS

So what does?
Usually when installing a ROM, /system needs to be wiped.
If /system wipe does not lose my IMEI partitions, I could just reflash stock ROM and my warranty is back?
Edit: Are you sure a bootloader unlock doesn't void warranty?
It was true for OPO, same goes for OPX?

I own an Alcatel 3(5052A) shipped with Android 8.1.0. It has a Mediatek MT6739 chipset. I managed to do fastboot oem unlock to unlock the bootloader and flash the official Resurrection Remix GSI successfully but when I attempt to flash Magisk patched boot image I get a fastboot error.
Code:
FAILED (remote: Only system partition can be flashed)
Does anyone know a method to unlock flashing for the other partitions?
I already tried 'fastboot flashing unlock_critical' to no success.
Thanks.
The same on alcatel 1
Im having the same issue at flashing twrp on alcatel 1 :crying:
Ya, me too, having the same issue. It says " Only system partition can be flashed", what does that even mean??? I've unlocked the bootloader Alcatel 1 & yet I get this error.
Is it something to do with the firmware we're on??

If you have your boot.img file go look up mtk-su (I've used this before it's a really good tool). if you don't already have root access then you can use that and run the following in the root shell:
mtk-su gives you a temp root shell for that session and your free to do as you please with it so hopefully that helps you guys
dd if=/sdcard/boot.img if=/dev/block/<path to boot>
Also if you need to try these both:
fastboot oem unlock_critical
fastboot flashing unlock_critical
And you should be good to go
Ensure you place boot.img under /sdcard or similar to where you'd like to flash

This means even with the bootloader unlocked the OEM has still restricted flashing other partitions. It's a custom implementation they have in place

Yes their Bootloader's are able to be unlocked. If that's the case your able to flash a custom recovery because signature verification is disabled in this state. You'd probably have to build the source code to be able to flash if not already available

Looking at said site it don't seem to be legit
So I found this thread and my long dead hopes of dropping a twrp into my device twitched, I mean after so many road blocks I'm surprised my hopes even budged but anyway here goes.
AOSP v32 android 8.1 installed on my Alcatel 5033A su version so I have root... ish
I can't write anything to the system and it stays there (after moving if it goes it's removed on reboot) and that's if I remount to RW cause otherwise even with root moving anything fails, all along I've been flashing my recovery with flashify and keep breaking recovery only to try fastboot method after realizing I can install a TWRP built for MediaTek MT6739 Chipset but that's how I saw the problem, it seems to be the same I get this error too >only system partition can be flashed<.
fastboot oem unlock_critical
fastboot flashing unlock_critical
Tried these codes and yeah I was able to do the unlock but afterwards I typed
Fastboot flash recovery <path> do you see my suffering T_T do you see cause I see no (-u)
rubbed it in my own face to see if I'd laugh too didn't even realize I typed this like three times without -u
So on reboot I see the start button checked logs on my pc I'm back at square 1 this phone is cursed like someone from the dev team just sat chanting for hours just to make my life miserable.
