Can't flash bootloader - LG Optimus 2x

I have bought a new LG Optimus 2x and it's still on 2.3.4 GingerBread
Battery drain is terrifying,I'm talking 100% over in 3-4 hours with little or no use
It probably has locked OLD Bootloader and it's on v20
I am unable to install Recovery and unlock bootloader
First I tried Upgrade with LG Support Tool,it crashed
I tried installing CWM/TWRP,I tried Rooting it(with All-In-One Toolkit) and I tried repartition it with ICS bootloader-IT FAILED
I then tried NVFlash and SmartFlash-FAILED
The problem I constantly get is NVerror 0x0 and command failure:bootloader download failed
*EDIT*
I tried Update Recovery in LG Support Tool and after the 2nd time trying it worked
I am currenly running ICS with NEW Bootloader but with OLD Bootanimation
However I still can't install RECOVERY nor Bootloader
I have LG Drivers Installed and APX Drivers installed
P.S. With my old 2X everything worked just fine
Please Help and thanks for reading

phone stuck on lg logo but can install the rom

hi i have a lg optimus 2x korea and i cant boot into custom rom.i installed cwm recovery and clear cache, data and successfully installed my custom rom but when i rebooted the phone i was stuck with the lg logo.can someone fix this.thanks also i forgot to backup.so how is their a method to return to stock
Try wiping everything and flashing ROM again. Give it a 2nd chance. Else you can download another ROM (in pc etc), put it in micro sdcard and flash it.
You can go to stock by using smartflash(search in Development section), but believe me its more pain n the ass to do that!! besides you lose you root and recovery too.

Use LG update tool to update to the latest country ROM and then you can get back root, custom ROM and so on....best always is the LG update tool which wipes all in a safe and best way
Try and try as I might, I can't get the LG software to recognize the phone no matter what I do.

Flashing Recovery

Hello, i just bought an LG Optimus 2x p-990, the first thing i did was updating to official ICS, but similar to my previous phone, i cant stand the stock rom and wanted to flash a custom one (havnt decided yet witch rom i want). After some trouble i finally rooted my phone, but now im stuck at trying to flash a new recovery. When i try flashing it through rom manager it says the device hast an official recovery yet, and when i try flashing this (http://forum.xda-developers.com/showthread.php?t=1098745) (note: i have usb debugging on and when i run it super user notifys that was given permision to shell) the cmd prompt opens for some seconds and closes again, and when i try to boot into recovery it goes to the stock recovery that wipes my phone.
Maybe this has been answered in here but believe me when i say i searched for the answer extensivly.
Hope i can get some help.
make it simple,install rom manager then install recovery..
I explained that i can not do it. ROM manager says the device is not listed and when i try to manually install the recovery it says permission denied.
Download and install nvflash driver(often called ATX) and install it. Then dl AIO all in one tool,from there you can install Cwm(can also be nvflashed) You can't use rom manager as it's not compatible with the new bootloader and partition table

[Q] LG SECURITY ERROR - Bootloop on Optimus Black

I had rooted my Optimus Black right from the first week i had bought in May 2012. Tried all the possible custom ROM's out there. Huexx's Zeus ROM was my favourite. But due to power problems (abrupt restarts and excessive heating during charging) I had to give my Black to service center for repair. I made sure that I switched back to stock ROM before I give it back to the service center.
Since then, I have been unable to ROOT it !!
Tried all the possible methods to root it:
CWM Injection, Smartflash resulted into BOOTLOOP's when i tried to flash older V10 and V20 firmwares. Only firmwares that worked were V20 F and V20 G.
This got me really frustrated as I just couldnt ROOT IT.
Today I flashed European V30 with the intention of ROOTING it with Unlockroot.
This time i was successful in ROOTING.
I installed Rom Manager, Flashed CLockwordmod Recovery. Rebooted into recovery and was greeted with a "LG Security Error" !!!! The phone just wont start.
What is going on ?? Is my bootloader locked ?? I dont know ??
Can someone please help me ??
Official ICS has bootloader locked.
lg putted a "crc check" on the bootloader so if its modified like your case, it gives a security error

Does that mean I am stuck on STOCK firmware from now on ?? This sucks.
I also came across things like for the Optimus G and Nitro.
Cant anything be done regarding this matter for the Black ?
Removing the very essence of andriod OS by LG by resorting to such stupidity really DISGUSTS me.
Please Dev's, come up with something. STOCK LG roms suck ass.
yes you cannot have cwm with that rom (atleast this easy)
flash another rom with smartflashtool
Download THIS and use THIS tutorial .. you`ll get Gingerbread rooted. After this install rom manager and you can install custom rom.

Tried it but FAILED.
STUCK on LG logo with the bottom lights blinking. Waited for more than 10 mins but just stuck there.
As I had mentioned earlier, can boot successfully through only stock firmwares like V20 F, V20 G and V30. Cannot flash patched roms and neither can I flash old V10 firmware as it results in BOOTLOOP.
:crying:
Help Me !

A lot of people flash a patched V20 and they forget to flash the Superuser and that results in a bootloop.At least it happened to me when I first rooted my OB in ancient times.Maybe this is the case.
P.S.:Got some tacos today?

EXACTLY !!
IT WONT BOOT AFTER FLASHING PATCHED FIRMWARE. STUCK ON LG logo with blinking bottom lights (strange but true).
Tried Rom Converter 2 and 2.1, Injection Method, everything.
Patched V20S, V20O does not work.
also CANNOT boot succesfully throuh a Stock V10 (so that it becomes easy to root).

I have tried all possible methods in the above links. Does NOT work. It wont boot through a patched firmware. Seems like LG has put some sort of a LOCK for the BOOTLOADER. Only STOCK V20G, V20F and V30 work.

Did you start smartflash as admin? Disable anti virus program and firewall maybe?
Sent from my LG-P970 using xda app-developers app
Hi
This happens if you flash original v30b with smart flash and the only way to go back to GB is flash a patched v20 version....
And it directly first boots into CWM...now dont restart....just flash your backup from your memcard,this will bring your phone back alive....
You can try copy any other zip version in your memory card if u dont have backup....
The problem is original v30 formats the phone in some diff format.....
Flashing it back with CWM...brings it back alive....
If you already flashed patched version then u can try to enter CWM by console...adb reboot recovery......else do as mentioned above....

[Q] Clockworkmod doesn't work on ICS

Hello
I could not find a way to make the clockworkmod working on my mobile..
I am using a P990 phone (German version made in Korea). I am running the official 4.04 lg room (v30a) - (it has 7 partitions). Using the AIO-P990-ToolKit_v5.6 I tried to apply the recovery ICS-cwm-6.0.2.5 (provided in the tool) and the latest one ICS-cwm-6.0.3.1.
following the steps provided by the AIO I applied the recovery the first time... it says that was successfully.. while booting in the recovery mode it doesn't open and start looping... (only the LG logo appears)
I executed the same steps once again. Then in says that was applied successfully, but te SW upgrade logo never becomes black. then I disconnect the cable and started in the recovery mode. It opened the recovery. I applied the root, looked fine...
while applying the Cyanongem 10, it said that was fine, but while bookting the old lg rom is back. Seems that it was not able to write the files inside the phone. I did the wipe in all the caches, and it did't book anymore....
I restored the original firmware (with AIO) and it is back. I tried once again with the new cwm version... it never works!
What can I do to change the rom in my mobile?

Hi!
You made a misstake when you flashed cm. You flashed a cm for old bootloader and partition layout while you were on v30a which is on new bootloader and partition layout.
Please use AIO-toolkit to repartitionate your phone to old bootloader and partition layout, and flash your cm you have downloaded.
Or
Repartitionate your phone to new bootloader and partition layout and download a cm which is for new bootloader and partition layout and flash that.

Help me revive my Optimus :'(

Dear friends,
My optimus 2x is giving me hard times from the very first step of rooting and installing custom firmwares.
My Optimus is from FIDO Canada. When I bought it, it had stock 2.3 V25H in it. I rooted it via AIO Toolkit and then the bad time began.
When I restarted after rooting, LG logo appeared for 3 seconds and then a black screen forever. Restarted again and again but nothing happened.
Then I changed bootloader to ICS and flashed Domination via recovery, restarted and the device never booted again even in recovery.
Downloaded V30a kdz for fido via lg and smart flashed it. Device started normally and welcome screen appeared, but touch wasn't working at all.
Thought it's a kernel problem, flashed different kernels and bootloaders and nothing happened.
Please help me ASAP as I am dying to use my phone.
Regards
Try installing stock ics with the all in one toolkit from spyrosk, I that will work for sure.
Maybe you can try after to root and install recovery from the toolkit.
