give me the exact thing you are trying to do. what you've done....have you flashed cwm at all? have you tried the one click method? are you positive you're following the instructions exactly? have you tried flashing stock recovery and starting over? when you hold down both vol. buttons and plug in your phone, do you hear the windows device connected sound? does it show in device manager in this mode? have you tried reinstalling the apx drivers?

Get Software

Grab the NVFlash 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 you 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

Make sure your phone is still plugged in to the computer! (some people, wow.)

Navigate the the directory you extracted the NVFlash archive to

Run a harmless command such as "nvflash --sync"

You should get something back like:

I have done all above you stated.I am currently trying to put the stock p999 rom onto the phone.I got the phone from my roommate after he got a iphone 4 it had i think its called cryogen mod 7 nightly on it,So i flashed it to stock using a oneclick method using nvflash(what i failed to do was see it was for the p990).So after it rebooted to stock rom i was happy till i saw it was stock rom for p990 which my phone thinks it is now.I get no radio signal,I rooted the phone and installed cwm on it and tried to use the p999 stock rom on it,It seems to go thur but stops at a progress bar when booting up,I tried this method that was a no go.The only thing that seems to work is the oneclick nvflash putting it to the p990 stock ,Im rele just trying to figure out a way to revert it back
[T-Mobile LG G2x] schmit:
So if I'm following you correctly, you are successfully able to get to CWM by holding Vol down and the Power button.. Then you're just about there...

If you're able to get in there... and are you are able to push the stock rom for the p999, you should be good to go.

Before you do the push of the p999 stock, are you going through a wipe first? On the first menu, there is a wipe option or 2, make sure you do those. Then on the advance menu, there are a cpl more.. make sure you do those. Then when done, I typically shut down and boot again into CWM via Vol dwn + power. Once in, then push your p999 stock rom.

If that's not working, then it's out of my league..
[T-Mobile LG G2x] Mvengeance:
I will try that I have not been wiping the phone before trying to push the stock rom in

Hopefully that will work all this LG bloatware and uk apps not my cup of tea,My phone went english on me thanks all for your help ill keep trying
[T-Mobile LG G2x] schmit:
So you have the stock p999 rom AND you are able to boot into CWM via the Vol Down and Power buttons? Assuming that's the case, then you're 90% the way there.

If doing all the wipes doesn't work, then download the stock rom again from these forums. My first attempt on flashing a zip file... it appeared to go through a few times, but never worked. I had to download a new copy. Others have had to do this too.
[T-Mobile LG G2x] crazythunder:
we are talking about the ROOTED stock rom, correct? you keep saying stock rom. the only stock rom i know of is in a bin file format, which i guarantee you're not flashing. if you are talking about the rooted nandroid backup, are you trying to flash that zip file? i hope not. please be as detailed as possible to the steps you are taking. can you access your sdcard from pc? if so, format the internal memory,the one that's 5.44 gb's.
[T-Mobile LG G2x] Mvengeance:
its the rooted stock rom and if i restore to the back up i made i can access my sd,

Someone else mentioned i would have to flash my baseband since it currently says unknown
[T-Mobile LG G2x] schmit:
Thanks for jumping in crazy. Ya, I get the terminology mixed up between a backup and the stock recovery..

If you used the OneClick CWM method as explained here: http://xdaforums.com/showthread.php?t=1056847 Then all you have to do is the last step called: Restore LG G2x Stock Recovery

[T-Mobile LG G2x] schmit:
Well, there are those that know more about this than I.. But that link I sent you is what most will use on a g2x.. So go through the process.. make sure you have the right drivers, etc. Then try the stock recovery in that link too. See how it goes. Outside of that.. someoen more advanced will have to help ya. Don't forget to do the wipes though..
[T-Mobile LG G2x] Mvengeance:
thanks for your help yea i tried the one click,Gave me that error the nvflash was giving me before
[T-Mobile LG G2x] crazythunder:
have you tried starting over by using this thread? http://xdaforums.com/showthread.php?t=1057849

and before doing that, uninstall all lg and nvidia drivers.
[T-Mobile LG G2x] Mvengeance:
An update it been fixed I flashed the baseband from tmobile onto it and it reverted back to stock right down to the 4g speeds..Thanks all that helped =]
[T-Mobile LG G2x] crazythunder:
where did you get the baseband?
[T-Mobile LG G2x] Mvengeance:
i actually got it from here

http://xdaforums.com/showthread.php?t=1037120

I used smartflash since my phone thought it was the p990 it worked,Then reverted to stock used the oneclick nvflash link you posted,rooted the phone and installed the leaked gingerbread.
[T-Mobile LG G2x] crazythunder:
i had a feeling that's what you did because i know there is no .zip baseband yet for the g2x. good move. i'm glad you got it fixed.

Sorry about that, the command was wrong and has since been corrected in the OP.

[T-Mobile LG G2x] DECIM8:
Yeah.... it flashed fine after noticing that the file name for the image was incorrect. I bet there are a few people getting very frustrated by this typo. I should have read the latest posts before trying to flash though, would have saved me some time.

jrharvey could u help me i have everything extracted for the ext4 support n tyen when i copy n paste it says no such command or something

3.1.0.1 worked like a charm, thank you to everyone who helped put this together.
[T-Mobile LG G2x] sarni84:
aluton how did u do it after u extracted it
[T-Mobile LG G2x] Lootes:
I had already flashed my device via the NVFlash method, so I already had all of the base files in the correct place.

I downloaded the new ext4 .img file and placed it in my NVFlash folder, no extraction, just placed the entire file in the folder. Pulled battery and plugged in USB while holding both volume buttons. Checked device manager to ensure it registered the device. Open command prompt to my NVFlash folder and cut and pasted the code from the OP.

Which file are you extracting?

On a separate note, something different I have noticed, is that now when I power with volume down to get into recovery, I get the initial LG logo, then I get a second LG splash screen, and then it goes into recovery. With 3.0.2.7 it went into recovery after the first LG logo screen.
[T-Mobile LG G2x] sarni84:
aaahhahhha yea baby omar ur guide worked awesome i was overlooking putting a file in a certain spot all is good
[T-Mobile LG G2x] sarni84:
aluton man dude this was a pain i did same exact same thing as u but u know what i typed start in command then copied n pasted n it worked

[T-Mobile LG G2x] tenbeau:
Thank you for this guide. I followed it to the letter and after finishing I realized that I had flashed the recovery to the external again and not the internal as I had intended. I notice in this sticky that there is only the external recovery listed and only the external commands listed. Is there any chance that the command line for the internal recovery could be posted? Also does having this 3.1.0.1 recovery give me both ext3 and ext4 recovery? Any and all help and info is greatly and warmly appreciated.

[T-Mobile LG G2x] jlevy73:
It appears that if you're going from ext4 to ext3 with new recovery, in certain situations can prove troublesome. I was going from cm7 +morfic to EB104F and never got past the LG screen. Nandroiding from an ext3 backup didn't work. Finally got Faux's AOSP rom to boot so not quite sure what's up. Have to do some more investigating when I get back home later tonight.
[T-Mobile LG G2x] KiNG OMaR:
Yeah seems like it is being a PITA going back and forth between nandroids/kernels/roms. But what can you expect, it's an unofficial build after all :(
[T-Mobile LG G2x] Jay2487:
Everything seems to work perfect but I get to the end and it says fastboot.bin not found bootloader failed. I have the ext4 recovery in the nvflash file but when I try to EXTRACT it to that file winzip says it's not ISO format? What program do I need to use? 7zip fails too, what am I doing wrong?
[T-Mobile LG G2x] KiNG OMaR:
Just drag and drop the .img file into the NVFlash folder :)
[T-Mobile LG G2x] Jay2487:
ahh so don't have to extract, finally got it to work, thanks!

For those that tried twice and couldn't get it. Keep pounding away, I did the exact same thing a dozen times and it kept failing, I did it once more and boom it worked.

SAD DAY

The new optional CWM 3.1.0.1 (UPDATED 5/24/11) bricked my cell :( It stays at lg and doesn't do nothing. Thankfully you made it easy to go back to stock. so i did that. cell reset and i was able to get into my cell. I then flashed the optional CWM 3.0.2.7 recovery and that worked fine.. Re flashed the new the optional CWM 3.1.0.1 (UPDATED 5/24/11) ext4 Compatible Edition: and it is bricked again.. not saying it is your fault by any means. just wondering if anybody else had this problem? im going back to the 1st ext4 recovery until something else happens in the communtiy lol... Just wanted to put the info out there

Thanks

*Edit just flashed the new recovery using gunnman's program... Still would like this way fixed cuz i like this way. I can reflash any recovery just have to have the image.. thanks again.
[T-Mobile LG G2x] crazythunder:
if you did all that, you were never "bricked". stop scaring people with false information. to my knowledge, noone has "bricked" their g2x,.....yet.

Wrong phone NVFlash help

Okay, I am a complete retard and if someone can help me I would be mighty grateful!! PLEASE HELP!!!

so from the beginning, I am trying to put NVFlash for recovery of my phone. My G2x

I got the NVFlash files from this site

well, it will not let me post outside links untill I post 8 times. but I installed the LG 2x ROM. LG-P990

followed instructions to the T, come to find out what I flashed to my phone is

LG 2X ROM

well it worked, did a great job at it too!!

wifi works, camera works, how ever I get no network connection to T-Mobile...

now I relized I put the wrong NVFlash on my phone, so I followed this thread to the T as well. No matter what I do, or what image I try to flash I ALWAYS end up with this error

"failed Executing command 14 NvError 0x12000

command failure: partition download failed"

I just bought this phone 2 days ago and I am very disappointed with my lack of common sense, and I cannot figure out a way to fix this. I know there is a way you can push a update using adb, but I cannot find any good walk troughs. Please, if anyone has any idea of what I can try next please try and help me. I am very competent when it comes to electronics and following instructions. and I do not want to be out 500 dollars, and I could break my phone and get it replaced for 130$ but I do not want to do that either....I would really really appreciate some hep. Thank you in advanced

[T-Mobile LG G2x] KiNG OMaR:
Most common fix is holding volume up + down through the whole process.

If that still doesn't work, try booting into recovery anyways, some people have said even after getting that error the recovery would stick. Hold volume down + power until you see it say "ANDROID" and then you can let go.

If that doesn't work might I suggest using a different USB port?

Also, I've heard of higher success on a Windows 7 PC.

If all else fails... try the one click recovery flasher ;)

Oh I see your problem. I just flashed the recovery because I didn't have the time to do it before. All you have to do is unplug the phone and hold down both volume keys and redo the command:

won't boot into correct recovery

For some reason unknown to me I am unable to go to the correct recovery I want to use 4.0.0.2. every time I try to boot into recovery from rom manager it goes to 3.0.2.7 , I want to go to 4.0.0.2 auto from recovery. What can I do to fix this?
[T-Mobile LG G2x] KiNG OMaR:
The guide was originally written to flash the 3.0.2.7 recovery. I just haven't gotten around to update it, been busy with school and life :(. Scroll down the OP and look for the instructions to flash 4.0.0.2. All the files should already be set up since you flashed 3.0.2.7 so just download the new recovery image, place it in the NVFlash folder and run the commands in the OP.
[T-Mobile LG G2x] sbch97:
Thanks for the quick response, I followed all the instructions and was able to flash 4.0.0.2 and I am able to get to that recovery by way of the power up and vol button, but still rom manager goes to 3.0.2.7 when I reboot to recovery from rom manager I also setup rom manager to "manual flash override" but it acts like 3.0.2.7 is still there instead of 4.0.0.2, do u think it is possible to have 2 recoverys? and if so how would I get to where there is only one recovery? thanks
