Okay,
So I suspect a few of you are going to want to jump on the NVFlash train that Paul is easing out of the station at the moment. NVFLash is the Nvidia utility for writing to the ROM on your Tegra2 phone, reading details and otherwise critical low level functions. For all intents and purposes this is akin to fastboot for many devices (although not the same as).
Whilst I'm not 100% certain I believe this is the only way to install a custom recovery on your Optimus 2x (when one is released) and therefore, if you hope to install a custom ROM, you will need to get NVFlash up and running.
Below are the simple instructions and links to the necessary files.
** WARNING **
NVFlash is a powerful utility that works at a very low level on your phone. There are few safety mechanisms built into a tool like this because it is intended for use by people with suitable training. NVFlash can not physically damage your phone but it can render it inoperable. It is unlikely to create an irrecoverable situation but it does have the power to create a situation that you can not recover from yourself requiring factory maintenance. Warranty coverage for your phone is not assured after using NVFlash. Please proceed with the use of the tool carefully and at your own risk. Neither myself nor XDA-Developers can be held accountable for any consequences from the use of NVFlash on your phone.

Get Software
Grab the NFVlash utility from here: http://djmcnz.batteryboss.org/stuff/NVFlash.zip
Extract the contents of that archive to a single directory
Grab the NVidia boot-recovery driver from here: http://djmcnz.batteryboss.org/stuff/nvmobileboot.rar
Extract the contents of that archive to a different directory
Prepare Phone
Power down phone
Remove battery
Hold VOL_DWN+VOL_UP & plug in USB connection from computer (note, your phone will not visibly respond but it will boot to APX mode quickly)
Open Device Manager in Windows and you should see "APX Device" listed with an error
If not, rinse and repeat
Install Driver
Right click on the APX device
Select 'Update driver software'
Select 'Browse my computer...'
Select 'Let me pick...'
Select 'Have disk'
Browse to directory to extracted the *driver* software to above
Select 'NVIDIA USB Boot-recovery driver for mobile devices'
Accept any warnings, including the big red alert (you may need to disable UAC)
Now in Device Manager under 'USB Controllers' you should have an 'NVIDIA USB Boot-recovery driver for mobile devices'
If not, uninstall the driver, reboot rinse and repeat
Testing
Navigate the the directory you extracted the NVFlash archive to
Run a harmless command such as "nvflash --sync"
You should get something back like:

This is as far as i get, is there a physical error on the phone or am i doing something wrong?
Any help would be greatly appreciated.
Try maliacrete thread dated 6/5/11 title big mess up after update. I tried it and it surprisingly work. Inatruction was in german tho..but np..google chrome can solvr the language issue. But beware..you'll end up with a brand new fone..
Newbie on the block.
Sadly the LG is not recognized by smartflash whatsoever.
Plugging the phone in while holding voldown yields no results, nothing on screen and nothing smartflash can see.
is the phone irreversibly bricked?
Have you change/swap the usb port as well like robbie said in the instruction? What i did was..i change the port, it still didnt recognise, the only thing pop up was lg logo..then i kind of give up and stop holding the vol key.
(Make sure u r on the 'ROM copy D/L' smartflash tab)
Now try the step again untill you see the lg logo (make sure batt off), then let go vol down key, then re-press the key..by now..the S/W loading pict should be seen n smartflash must be able to detect ur 2x n will fill the blank. Now press start on the smartflash, sit back n let the rest done by smartflash. Once complete, unplug, batt in, and restart as normal. A new born 2X should be ready to see what lies ahead of him/her..
Im still trying to recover all my setting, data n app manually. Btw..dont forget to bckup after cwm.

is your phone an LG O2X or is it a T-mo G2X ?
Yeah, you just mentioned 2 phones in your post. the O2X P990, and the G2X P999. So we're guessing the problem is knowing which tools and ROMs work for your exact model.
Btw, there's a separate G2X forum if that's the phone that you have. This is exclusive for the P990.
Friends..i am beginner+ to this forum.. i got stuck in a bad problem(bootloop) below. Please help me to save my O2x
Thanks in advance and appreciate all your help ..!!
Reason for bootloop:
===============
Flashed temasek CM7 and it worked perfectly.
Then flashed Horsepower 2X extreme kernel and it came up and worked.
Then when i re-started the phone, it enters into BOOTLOOP and stuck there forever.

Power it off, remove battery, hold vol- and insert USB cable.
If it shows something about SW Update on the screen, then just smartflash a stock ROM, then start again. Saves dicking around.
sw upgrade boot doesn't work either
Thanks for ur reply Rusty...!!
I tried SW upgrade boot also, it didn't work .. flashes lg logo and turns off... if i keep on holding vol - button, it blinks again and again.
I think i bricked my phone.. Internal sd-card /emmc,/cache)is not recognized/mounted.
It's pretty much impossible to brick it. NVFlash will fix it.
When you tried, was the phone plugged directly to the motherboard or through a hub/front ports? Direct is best.
Yes, i tried through serial port and tried with other port also, didn't enter S/W upgrade screen.. (Mine is Dell XP15 - win7 )
Have installed latest LG drivers and nvflash drivers are latest and showing up in device manager also..!!
Through nvflash it stucked - bad data or hangs for hours..!! (have tried changing data cable too)

Before giving up, borrow some time on a desktop computer, connect directly to a port on the motherboard, try again. Use a USB2 port.
Re- Use a USB2 port.
When i connect to usb3 ports, it detects APX device and 'NVIDIA USB Boot-recovery driver for Mobile devices' appears in device manager.:angel:
But when i try usb 2 port, it prompts as unkown device(usb device not recognized) -[ Lg drivers work with usb 3 ports] and not able to proceed further.
I have always used usb3 ports for rooting O2x and all- it went fine, should i still need to debug on usb2 unknown device issue ?
Nvflash worked..enters sw upgrade screen
Friends, nvflash works successfully and files sent successfully and phone enters S/W upgrade screen.
If i release usb cable, put the battery and power on with vol-down, it again enters into CWM and not S/W upgrade screen.
Need to know what are the next steps to do , also what are the files that i have to put in sdcard ?
addition to this.. adb also working..
Friends,.. now nvflash works and i am to do some basic ADB commands also..!! [Smartflash not working - due to phone not entering s/w upgrade]
C:\Users\Senthilnathan\AppData\Local\Android\android-sdk\platform-tools>adb shell

Need your help - What are next steps i should do ? What are the files i need to download to make my O2x work? :fingers-crossed:
Well if you can ADB in recovery, I guess you should download a ROM, stick it on your SD card and flash it.
OR
Remove battery, hold vol down and plug in USB cable to get the S/W Update mode, then you can smartflash.

Hi vsnstarguy,
I have a situation like yours. My device is dead and nothing shows on screen. I've tried that methods, nvflash, smartflash but my device is realy dead and I got the same status like you:

Hekp me!
I've opened a thread about this but nobody could help me yet!
Thing is, most people manage to get passed that point. If you've plugged directly into the motherboards USB ports, have you tried another computer?
@cl06 - nvflash and adb works..!!
@cl06 - Dude, is you phone p990 or p999 ? you seem to be trying with p999.
Nvflash p990 correctly, it will work.. (got this from Rusty thread)
or navigate it to your nvflash folder for p990 and try below command--
nvflash --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 14 cwm-int.img
In above nvflash command - after download for p999 it will be 5 for p990 it will be 14.
For some intermittent issues, i changed usb cable and now nvflash works but im still in bootloop for which our friends here will help us
I have LG Optimus 2X P990 which was working normally till last two months.
In last two months it get slower and slower and now wont turn on and wont flash.
When I connect it to PC - PC recognize it and I can start flash process, but it always stuck
at the same step :
