Problem Rooting - T-Mobile LG G2x

Hello,
Hopefully everyone is having a great night. I'm having a slight issue rooting my phone and have searched for a solution, all to no availability.
Anywho, I've been following the official G2X GB Root thread (http://forum.xda-developers.com/showthread.php?t=1056847) and have gotten to the part of flashing NVFlasher. Everytime I start up the program and plug the USB cable into my phone (with both volume buttons held) and run the flasher, my screen's backlight comes on (screen is still relatively black) and I don't get the S/W message that I should be getting.
I've tried on my desktop and laptop and have gotten the same results from both. Does anyone have any idea on what it could be?
Thanks in advance.

When you hold both buttons while phone is off, and plug in USB, you'll only hear the noise from your computer when something is connected.
The phone will look like it's still off. When the computer makes the noise you can let go of the buttons, then run nvflash.
That's if you installed the apx drivers.
If you're still lost then have a friend/pay someone to do it for you.

Hmm I read that you have to keep the volume buttons pressed until the flash completes.
Anywho, it seems that the flash has worked. It's just nothing was displayed on the screen. I rebooted the phone while holding volume down and low and behold, I was sitting in CWM.

If you upgrade your ROM with KDZ or official method, you can try this method to flash and root your phone at one time.
When flashing kdz, LG update tool will extract files to %ALLUSERSPROFILE%\LGMOBILEAX\Phone. If we replace recovery.img with CWM recoery before it write recovery, CWM recovery will be available when finished flashing, so that we can root the phone easily.

How to unbrick the soft bricked Captivate

NOTE:
So far this has been the only sure fire method I've found to 100% get around any brick situation regardless of firmware, etc. This only works for the captivate, not any other galaxy s variant.
Situations: phone-!-Computer / no download mode
Black Screen / RST_STATUS 0x0
Procedure:
1. Remove the battery, external SD card and SIM card.
2. Wait 10 seconds.
3. Open odin3
4. Connect usb cable.
5. Hold volume up + volume down + Power.
6. Insert battery.
7. Release POWER BUTTON ONLY.
You should now be in immediate download mode.
Please forgive me if this is duplicate some where, but I tried every procedure I could find on google to no avail, then accidentally found this method just before I was going to box it back up and see if my buddy at AT&T would make me eat it or not.
My situation was: Launched Odin3 to flash H3 firmware, died twice in the middle, and on the third time locked up half ways just at the beginning of factoryfs.rfs -- Then the phone did nothing. Blackscreen is all. Interestingly enough, while in the state if you hold volume up + power, it will give a hw diagnostic screen. Beyond that I could get no where. Just a black screen, no acknowledgement when connected to PC, no charging indicator, nothing.
If this is a dupe Im sorry but this method I could not find and hope to make it readily available to people who may think their phones bricked.
Update 12/22/2010:
How to BRICK the phone / WARNING!!!
If for whatever reason you decide to use Odin to flash a stock GTI9000 ROM and manually add the kernels and modems using a "pure" 2.2.1 sammy rom. BEWARE.
Researching a lot, it seems the consensus is that the sbl in the 2.2.1 versions of the GTI9000 has *hard* download mode crippled.. Meaning if there is a software screw up YOU CANNOT USE A USB JIG OR ANY OTHER METHOD OF GETTING THE PHONE IN DOWNLOAD MODE!!! To fix it you'll need a new one or JTAG to replace the bootloader.
As far as I can tell, beyond getting completely rid of the AT&T logo, there is no need to flash boot/sbl to get the "purity" of the 2.2.1 sammy roms.
Extract all files from the tar EXCEPT boot/sbl and re-tar and flash just those to avoid overwriting the stock captivate boot loader.
Also, it does not appear the boot/sbl from the captivate 2.2 leak suffers this same problem.
For any one iffy on bricking their phones, stay away from roms that remove COMPLETELY the AT&T logo on boot. This generally means the boot loader has been messed with any you may be screwed if you soft brick the phone. Most CWM roms dont overwrite the boot/sbl, but some can and do. Watch yourself.. if it the AT&T logo goes away COMPLETELY, I recommend flashing JF6 with One click while the roms alive using adb reboot download and try another rom.
thanks!
worked...took a few tries but some trick with this captivate to get it into download mode.. i was totally bricked too, diag screen with PC/Phone icons and exclamation mark. for me 1.) plug usb, 2.) hold power and vol up/down and connect battery (it fell out) and i was in download mode
I guess a similar procedure was on the odin3 one click thread, but there is something different in your procedure, it's not my case but it would be nice if some people confirms this as this may be useful and if it really works it should be included in odin thread
What worked for me was: Pull the battery, sim and micro sd card. Open odin on the PC. Insert the battery. Hold vol up and down then with the buttons held connect the usb cable. Just remember to plug in the usb cable with the vol up and down held in and odin must be open on the computer.
I also ran into the vol up plus power red text screen. Interesting to note that one of the fields will change depending if the usb cable is connected or not.
mine is dead
mi samsung captivate was working great but, suddenly it go black and only the touch bottom have light, when i plug it in the a/c it show is charging. i'm mac user and a read that i ned to use odin3 but it not work on mac. how i can unbrick the phone???
is rooted with one click lag
the dbdata was modif to
thats all
HEEEEELLLLLPPPPPP
Odin will not open on the mac?
Cant you use a virtual machine and use Odin on a Mac that way?
Or else take the odin 3 single click for JF6 and use on a friends Windows Computer.
Please help - unable to flash back with Odin3
I have pretty much tried it all at this point and am trying to figure out what I'm doing wrong.
I followed the directions just in case get to the big yellow triangle with the droid shoveling and the screen stays at "downloading, do not turn off target..."
Of course I had Odin3 open already but its not seeing my phone, USB drives are installed am using Odin3 ver. 1.30.
Any help would be appreciated, TIA!

Best way to get download mode is use adb and type adb reboot download.
Or follow the volume up/down held with odin open on the computer, then you plug in the usb cable to the computer.

Just sharing the info! Makes you think twice about trying something else don't it?
does not seem to work because as soon as my battery touches the contacts it goes to the diag screen. do I have to release the power button in super human speed times there?
looked at all threads here, looked elsewhere -- there are some that are not fixable. Wanted to add that in case others come here and think that they might be the only ones that can't get it to work.
Ended up sending mine off to Samsung to reset today. :/
I love you! I called AT&T to send me documentation to sign and it was going to cost me 125 dollars to get it replaced even with warranty. And you fixed it !
i have tried just about every single method detailed in these forums, and nothing works.
Trying what OP suggested just sends me to the battery charging animation screen.
Anybody have any ideas ?
file analysis
I keep can get to the download screen and I hit start and it does the same thing everytime it just does File analysis i cant figure what i am doing wrong here somebody please help me
I think the issue was it had something to do with 64 bit windows 7 i just re did the stock rom one click solution and it worked fine

Thank you for sharing your experience.
I don't have a Captivate yet but am doing research on it and hopeful of getting one. I am confused about one thing.
Every where that I have read about how to enter Recovery mode or Download mode on the Captivate using the 3 button method, it says holding down both Volume UP + Volume Down (plus Power button) will enter Recovery mode. But you say it enters Download mode which is confusing to me. As I recall, to enter Download mode you must press the Vol Down only (plus Power button). Could it be because the phone won't go into Recovery mode, it goes into Download mode instead? Am I missing something?
Thank you!
Download mode is for updating the phone's firmware.
Remove battery, plug in the usb cable to the phone, open ODIN on the computer (need usb drivers installed before hand) on the phone hold volume up and down then plug the phone into the computer. Your phone will say DOWNLOADING. This method works even if you run into problems and the phone refuses to boot properly.
Recovery mode is for installing Update.zip. The method is tricky but involves holding volume up/down and power, the phone will show ATT then go black. It will repeat that but after the second time it goes black let go of power.
If that doesnt work, android debug tools ADB reboot recovery will work even better.
Or root the phone and use Clockwork Rom manager to boot into recovery, just press the menu item.

Thank you askpcguy! I understand the difference between Download and Recovery modes.
So the procedural difference here is having the battery in + Power button, versus battery not in (use USB cable instead) and no Power button. Can the phone get power from the PC via the USB cable? This seems to differ from what the original poster said about download mode. Perhaps OP could edit his original post for clarification? Or am I still missing something? Thanks to all
The phone does get power from the USB cable.
The difference is one procedure uses the USB cable (download mode) and the other does not (Recovery mode).
The volume up+down method does not use the power button, the phone is powered on into download mode once you plug in the USB cable.
We say pull the battery to get the phone powered off. If a firmware flash stalled or doesn't complete, pull the battery and try again!
I now understand the precedural difference.
Thank you askpcguy!

[Q] Can't get into S/W!

Two weeks ago I had an ICS rom installed and was tired of the poor battery life, so I tried to unroot my phone and bring it back to stock to start over later. I got the stock 2.3.3 installed and decided not to unroot and just use the rom.
I followed this guide: http://forum.xda-developers.com/showthread.php?p=14159600#post14159600
But I didn't actually use SOC to unroot, because I wasn't sending my phone back to TMobile.
Today I was looking to see if there were any ICS roms that I might like to try out and found HFS. I downloaded it and tried to boot into CWM (Power + Vol down), and instead of going into CWM, it did the little android install splash screen, and just wiped my phone. So I installed RomManager and tried to install the rom through that. It rebooted, and did the same thing. So I "fake flashed" CWM through RomManager, and it booted into CWM finally. I thought I was in the clear, so I factory reset, wiped everything, and installed the HFS rom. It ran all the way trhough and installed successfully, until I rebooted. Now it's stuck on the white LG logo. I can't boot into CWM! It just goes to the android update splash and restarts.
To make things so much worse, I can't even boot into S/W update! I remove the battery and hold both volume buttons and plug in the USB. It does nothing. No lights, no driver installation prompt on my computer. Nothing...
What can I do at this point?
You need to re-install CWM, when you went back to stock it probably reverted your recovery to stock as well
Alright, I can get into s/w update by holding only the down arrow... But now I can't get NVFlash to acknowledge that my phone is plugged in. I've installed the LG drivers, ADB drivers and the LG Modem drivers. It doesn't ask for the APX drivers, although I've installed them in the past...
What do?
Just making sure, you are removing the battery, holding down the VOL up/down while you are plugging it in W/O the battery?
Yes I am. But it doesn't work if I push both, then plug it in. I only push the bottom and it boots into S/W
FYI, never, and I mean, NEVER use ROM Manager to flash CWM Recovery. That's like asking for a brick.

Re-read his question. In order to get into apx mode you must remove the battery, keep it out, and, while holding the volume up AND down buttons, plug in the phone. If you already have the drivers installed itbwill not prompt for them. Just. Flash cwm with nvflash.

My apologies for any misunderstanding as my answer was really short. But what I meant to say was, when I remove the battery and push both volume buttons down, then plug it in, I wait for 3 minutes and it still does nothing. But if I remove the battery, hold only the volume down button, it will boot into S/W. But when I use this method, it doesn't show up in the device manager as anything. I only get the sound of connecting a USB device, other than that, it's just not recognized by my PC. I've tried to run NVFlash anyway, and it says USB not connected. I'm at a complete loss...
Well I actually had a problem like this ( the not found usb part ) ehen I "bricked" my phone and what I did was I kept trying this for about 5 minutes and it worked. So my advice ie to check if you have the USB driver installed then keep trying to NVFlash.
If I helped you, push the thanks button for goodness sakes!

Galaxy S 4G Issue

I hope i'm in the right board for this, if not i'm sorry, but i've run into a major issue recently.
While working on installing MIUI on my Galaxy S 4G from Tmobile I hit a point where it turned offand absolutely nothing is happening. I don't remember when exactly this happened but I think it was after something with odin.
It's not detected by Kies or anything, it's just off and nothing can get it to turn back on. I left it on the charger and went to sleep last night, this morning it still isn't doing anything.
Any help would be greatly appreciated.
In the state that it's in, I believe the phone will still boot into Download Mode, even though nothing appears on the screen. Odin will still recognize the device if it is booted into download mode.
Just open the back cover and remove the battery. It is also recommended you remove the SD card and SIM card. Put the battery back in, and connect the usb cable while holding the power up button, and plug it into your computer. Open up Odin and it should recognize the device still. If it doesn't, try these steps again until it does.
Since you were trying to flash MIUI, we should be safe to assume you're running Gingerbread on your SGS4G, so you can download a stock, Odin flashable ROM from here. Flash that using the PDA in Odin, let it reboot, and you should be fine again.
If you have any further questions that need answering, refer to the SGS4G community.

Thanks for the help, currently i'm attempting to get Odin to recognize it with no success. I've gone through the process about 3 times and will continue till I hopefully get some results. If it makes any difference I don't hear the sound of windows detecting a new USB device anymore like i use to when I would put it into download mode.
As far as I remember, Windows doesn't make a sound when booting into Download Mode. I just realized I made an error in my previous post. You need to be holding the volume up button when you plug it into the computer. In some cases you will need to hold the power button at the same time. Try giving it the volume up + power on button when you plug into your PC. Make sure you're holding the button combo long enough for the SGS4G to power on and into Download.

[Q] Did i just brick my first phone.......?

was installing ARHD 7.0, which ive done several times and now the phone wont boot after a reboot. i can vol/pwr up to get to the splash screen, but cannot get into fastboot/hboot or back into twrp. any ideas?
Belay my Last!
Fortunately I found a post from the M8 thread and was more or less, a timing issue on my part. Thanks to Tikerz for his post/reply
Quote below:
"When you plug it into the computer does the computer make a ding sound that it's connected? If so, then press power and volume up until the disconnect ding sound which indicates it's rebooting and then immediately press volume down and see if you can get into fastboot. The timing is tricky so I've found using audio cues from computer can help if the phone is messed up."
I had to do this also. It will work. I thought for sure I had bricked my M8. But if u hold power and volume up at same time time screen goes black..then let go of power and volume up and hold volume down till u see fastboot. From there u can fastboot flash RUU package. I say that cause I personally found that restoring a backup of re-flashing ROM didnt work..at least for me.

LG G2

ok, so after rooting and trying to install CWM, my phone will not boot, only blinks red light. I think when i was trying to flash img files over to the phone, i lost connection and wasnt able to transfer the bootloader.imgs to the phone. Following this, when i plugged it in, i would get numerous drives trying to open, but said they needed to be formatted. I then tried the UBUNTU method, which led to my phone not even being recognized... but my question is, why is it so tough flash a recovery to the phone now? I remember when I had my S3, it was much easier to do this....i have a lg g2 if that helps....i have tried all the guides, and like i said, all i get now when i hold the power button and volume down, is 8 blinks of the red light...has anyone had this problem, if so what did you do to solve the problem?
Can you get into download mode?
Power completely off.
Plug the Usb cable into a computer.
Hold vol-up while plugging in the Usb to the phone.
If you can get that, then you can use LGFlashTool to reset.
