Hi!
I recently bought an AT&T Optimus G E970 (unlocked) and have rooted it using framaroot.
Now, when I try to unlock the bootloader using Freegee app from playstore, it FC's and phone reboots. the AT&T power-off animation is not present in my phone. When I try to boot into bootloader by pressing Vol. Up + Power key as given here http://forum.xda-developers.com/showthread.php?t=2001655 , the phone boots normally but not into bootloader.
Phone came with Jellybean 4.1.2. Last time when Freegee app finished downloading the .xml file, the phone got soft-bricked and I have to use LGNPST method to restore it using the stock firmware .tot file.
I'm not sure what is wrong with the phone. Is there any other method to unlock the bootloader offline?
I think this is what you need:
http://forum.xda-developers.com/showthread.php?t=2230994
It still uses LGNPST, but it gives you an alternative to flashing the entire stock .tot.

Tried both of them. Got stuck at LG logo in the first one and then at Google logo in the second one.
Then I tried the .tot file afterwards and got out of the mess. Still unable to boot into bootloader using Vol Up + power.
Problem solved!!
1. Installed Busybox.
2. Reinstalled FreeGee
3. FreeGee downloaded the xml files and img files.
4. Installed CWM 6.0.4.7
5. Bootloader finally unlocked!
Now time to flash Paranoid Android

My bro accidentally clicked on OTA upgrade. I have bootloader unlocked , rooted P765 with cwm 6.0.2. I searched this forum for solutions and got some.Unfortunately none worked for me.
http://forum.xda-developers.com/showthread.php?t=2247371 - this method did not work . my phone also has some issues with USB i guess. Everytime i connect to pc , i get device not detected error. screes attached.
http://forum.xda-developers.com/showpost.php?p=40423549&postcount=2 ----this did not work. same as above.
i also tried with exitrecovery.zip . It ran successfully from CWM but everytime i boot, phone still goes to CWM recovery mode.
exitrecovery has following code
busybox echo -ne "\066" | busybox dd bs=1 seek=4107 count=1 conv=notrunc of=/dev/block/mmcblk0p8
I did trial and error with mmcblk0p till 1-20 with no success.
Here comes the saddest part...I also went to LG service centre. He also couldn't help.That guy told me motherboard is dead due to rooting.
I am sure that my p765 is very much alive.
I can go to Software upgrade mode on my phone, but my pc doesnt recognize it. I have latest LG drivers installed on my system.
NOw i think only way out of this could be a script to flash from CWM. Please help me!!.
I tried flashing other roms like Superlumina,Avatar. Also tried Ubuntu touch with no success. Still goes to CWM.
I am on JB India V20A.
Thanks in advance.

:crying: any scripts like exitrecovery to flash?? dying here seeing the state of my phone!

You need to install fastboot drivers: http://forum.xda-developers.com/show....php?t=2119090
Turn off the phone and remove the battery. Download THIS and exctract it to C:/. Open device manager in windows (Rigt click on Computer > Manage > Device manager) and connect your phone without the battery to pc via USB cable.
'This' link is broken... u have the files brother?
SOLVED
I connected my phone in Software upgrade mode. Same error pop up- USB device not recognised.
Selected 'Options' from LG User support tool and clicked 'Update recovery'. Entered my mobiles serial number.
AFter around 3 hours of download, my device is detected on my system!!! I seriously did not do anything on my system.
AFter the download was complete, the update was installed. My P765 is BACK!!!!

I'm a new member to this forum. Need your help.
My P765 got stuck up with CWM recovery after an OTA update. I flashed some custom rom's but still it does end up in CWM recovery only.
Could you please upload the CWM zip to flash the stock recovery. So that I can get to back to my P765.
I have been searching in all the forum. Finally found this to get solution. Thanks in advance

The following will work with all OTA boot loops to recovery. The guide is for p765 but it will work with all variants. If you flashed a custom ROM trying to fix the problem, please restore your stock rom backup. Also, if you still have artas182x locked bootloader recovery (or you removed any system apps), the update will fail, but you will be of the loop
what kdz are you currently on? I made the zip but i need the extracted p765 recovery.img.
If you have the kdz please extract the recovery.img (look at my signature on how to extract it).
i could give you the p760 20b recovery.img but I think it would be best to use the recovery.img of the current kdz you are on (to be on the safe side).
Note: if this doesn't work, you will need to use the unoffical fastboot. So you might want to get fastboot setup before trying this. Actually, you probably won't need fastboot, but you will need to restore your custom recovery.
Or use the longer method (takes more time, depends on your download speed), LG mobile support tool.
Once you get the stock recovery.img for your kdz, Open the p765_stock_recovery.zip and copy the 3-recovery.img into the zip file.
Note: Don't change the name of the recovery.img or it will not work
The recovery must be named 3-recovery.img
Place it on you sdcard and flash with cwm and reboot.
Or sideload into your phone with cwm and your computer
Code:
adb sideload p765_stock_recovery.zip

I just used casual to root and unlock my note 2.i have root and it booted up on twrp but I want to check if I am unlocked bootloader. Is there a way I can check? In my about phone my status says normal
If the bootloader was not unlocked it would overwrite any changes you make to recovery and system files. So as long as you can reboot without losing TWRP or any custom ROM you've installed you're golden.
Unlocked Bootloader?

It's been a while for me since I rooted my phone, and I don't know if I unlocked my bootloader either... I have never installed a custom ROM, I only rooted so I could tether. But now that the new OTA update keeps trying to install itself, I need to fix this because it's extremely annoying. I read a thread that said I need to flash this: http://forum.xda-developers.com/showthread.php?t=2578458, but it said that I need my bootloader to be unloacked, and therein lies my question...
Am I thinking this through the correct way?
If you just want to stop the update notification fteeze SDM 1.0

That is the correct thread. Easy way to check is to boot into recovery and see if there is a custom recovery installed. Power down your device, hold down the volume up + verizon button, then power up. Hold volume up + verizon button until you see the galaxy note 2 splash screen. If it boots into TWRP than you're still good. But you will probably want to update to the latest version of TWRP before you go installing any new roms.

Thanks Jiggabitties, I updated TWRP and downloaded official firmware.md5 file and the Mj9 DeOdex file to my pc. Should I transfer those files to the sd card in my phone and install from the TWRP menu? If so, I do the official firmware file first, right? Then the deodex...?
Thanks for all your help man

The firmware update is done in ODIN and the ROM is done in TWRP.

Yes start by transferring the files to your SD card.
The firmware package from that thread is meant to be flashed via ODIN. If you are not comfortable in flashing firmware via ODIN then use this in it's place... https://www.dropbox.com/s/lz29kvrvzfttfpu/MJ9ModemParams.zip This is a TWRP flashable version of the firmware.
Place the MJ9 Deodex and the modemparam.zip I linked to above on your SD card. Flash the ROM file first, then the modemparam.zip. Then clear cache/ dalvik and reboot. That should be all you need to do. If when you boot you don't get service, then you will need to go ahead and flash the firmware vid ODIN. Some users have no issues with the flashable version that I linked above, some users do.
I recently rooted my phone. That worked no problem. I then tried to install CyangenMod through BobZhome ROM's. I can't post the link but it's easily found on google. I tried installing his CM11. I used the CWM file he included and used the app he suggested. I loaded the file on to my SD Card and click on reboot to recovery in the app. My phone said Security Error under the LG symbol as it's booting. I've read many people that have the same problem. But my phone isn't able to do even the basic things they tried. I tried hard resetting it. It showed up with the logo and Security Error. I can't even put my phone into S/W mode. It just loads up the same logo and Security Error screen. I don't know what else to do.
You need to install fastboot and flash the uboot and xloader for your phone model, and whatever version of android your phone shipped with(If you don't remember, use ICS).
http://forum.xda-developers.com/showthread.php?t=2119090
Then once that is finished, you need to download a version of android for your model.
http://forum.xda-developers.com/showthread.php?t=2107971
Finally "Offline flash" the kdz file you downloaded.
http://forum.xda-developers.com/showthread.php?t=2085344
The reason this happened is that you have a locked bootloader, this needs to be unlocked in order to flash custom roms. It is especially hard for this phone.
Hi! I've managed to brick my device (d610ar) badly, i think
the device doesn't boot normally (message "Secure booting error! Cause: boot certification verify.", and i am stuck there), can't charge it with the wall charger, and the only thing that works is download mode; but flashing a kdz with LG FlashTool (the way i went back to stock a few times) says flashing and at 2% (or 3% sometimes) it says that doesn't find the device, that i have pull out the battery to reconnect my device again and when i do that it does the same thing on a loop, asking to do it again later..
the funny thing is that it appears on device manager on windows, on com port 11 for example, but the FlashTool doesn't recognize it..
so, i can't flash any kdz and doesn't boot.. i've read around here in xda to enter fastboot to fix it, but.. can this device enter fastboot? i couldn't do it, tried adb too and couldn't make the device visible..
i, before this happened, had multirom installed, rebooted to recovery and deleted secondary roms to install in primary rom cm12.1.. there started to happen strange things when rebooted normally to configure it..
after a while trying to boot found around here in xda too that i could enter twrp recovery via hardware keys to reinstall again, so got into it and installed a flashable zip to come back to stock KitKat directly, that have worked for me before..
after that rebooted and i can't do anything else than download mode..
i kinda figured that the problem must be that multirom injected the boot sector after installing the stock flashable zip, and when i did that restored the stock aboot and abootb (these, modified carefully, allowed us to unlock bootloader and flash recoveries, etc, etc.. ; by the way, many thanks to the devs that discovered it and made the guides!)..
now i have read the instructions for flash via fastboot the stock boot.img and so pass the security verification, but i can't enter it..
so, what do you think that could be the next step? or is it really hard bricked and i should forget about it? i'm really hoping to recover it but i don't know what else to do..
sorry for the bad english, not my primary language
thanks for reading and i am hoping to hear some suggestions!
He is not hard bricked you need to flash stock boot and reunlock bootloader if you have custom recovery still installed, but go first with the eazy way search xda about lg flash tool stuck at 2% there some guides to help you get kdz flashed
Thank you very much!

Thank you very much! You made me realize why wasn't working..
Because of you, i started to search threads related with the "flashtool stuck at 2%" and one of the things to look at was a txt file to see what was the problem.. there i found out that the lg FlashTool recognized my device as LGD618..
That's when i realized that i must've messed up when i flashed a lollipop flashable zip for the D618(a while ago), "converting" my cellphone on that model.. so when i connected on download mode and put the LGD610 kdz the comparison of cellphone model and binary model didn't match..
Solution was to flash LGD618 kdz, boot up normally, install towelroot, install supersu, edit a line on build.prop
from persist.multisim.config=dsds to persist.multisim.config=none
rebooted and that's it.. everything works perfectly now! i won't be doing stuff to it for a while
probably will stay stock like that, because now i will be using an OnePlus One in a few days and the G2 mini will be used by my mother, i think..
Thanks again! You saved my device for being bricked forever
i glad i could helped you :good:
I tried installing kitkat having installed lollipop and did not work, also I tried installing lollipop and nothing. Well I think this update lollipop are adding some kind of lock to disallow downgrade or upgrade by KDZ. I try other methods, unlocking bootloader, and install a aboot.img, bricked my phone. I recommend that you do not attempt to unlock the bootloader and install any system image that is not official, or may end up with a dead device.
so.. i have an Lg d618 rooted and running official L 5.0.2
i wanted to flash a custom recovery so i started with patching bootloader using this thread

then i installed TWRP using this thread

Followed you from the other spot...
It sounds like Flashify plunked recovery on your boot/kernel partition (assuming your recovery you described is still stock - that is - Andy laying down with the front panel open). So, I would suggest to ADB push your official L 5.0.2 boot.img while in TWRP and flash that (to boot), and you should be golden.
Also, from my perspective it's hard for me to say your bootloader is acting up, as I have a different LG device and it's bootloader does not have fastboot. It's front-end is only a shim that makes you factory reset to get into recovery mode (it's only function).
Hope this helps.
