I thought my phone might have been hosed, but fortunately I was able to revive it using the initial directions along with using XP Mode via VirtualPC in Windows 7 Pro - 64 bit. It required reattaching USB during the process a couple of times when it disconnected, but it worked well once I understood that you have to reattach the USB as soon as possible. That said, I wasted many hours trying other methods in Windows 7 itself before trying the method that actually worked, so it took a lot longer than I wanted.

I hope others don't lose hope, as it seems harder to fully brick the phone than I had thought. It's frustrating regardless that the software is so buggy though, that's for sure.
[T-Mobile LG G2x] gaww:
Not so much the hardware - but the software. The LG Updater across the board on many devices is know as a "bricker". LG, like the maker of another Korean tech product I have, seems to be way behind the curve in the software segment in supporting their products - backed up by practically nonexistent customer and tech support.

When you get your new phone, either try right away again to update it (and it it fails - get another), or take advantage of all the alternate ROM's on XDA and then stay totally away from the LG Updater.

Maybe try with a different computer.

In any case, you should be able to get a replacement from TMo.

You can tell then the LG Upgrader did it. They had been telling people to use it, but now may be backing away from that, as they have had to deal with an increasing number of replacements because of it.

Thank you TMo - damn you LG.
[T-Mobile LG G2x] cpom1:
Thanks for this guys. Definitely helped.
[T-Mobile LG G2x] JosephSmith000:
Ok i went to the tmobile store and they ordered a replacement for me. The problem is that my phone is rooted, so will that be a problem when I send my old g2x back? Would they bother to check when the refurbish tech try to fix my old phone?
[T-Mobile LG G2x] dachinaman:
I did just that and got my replacement today with the 2.3 already installed
[T-Mobile LG G2x] JosephSmith000:
Was your phone rooted though?
[T-Mobile LG G2x] gaww:
I returned one rooted G2x. Could not get back into it to change it, It had been reverted to stock Recovery and froyo however.
[T-Mobile LG G2x] JosephSmith000:
I've tried putting my phone back to stock Froyo, but the program keeps saying USB not found. I believe the tech at the store did also tried putting my g2x back into stock Froyo, but he also failed. Hard reset doesn't work, the screen is always stuck on the s/w upgrade. Is there anything I can do before sending my phone back to lg?
[T-Mobile LG G2x] gaww:
If you have CMW Recovery, you could take out the SD and copy a stock ROM onto it (it can be found in development forum) and flash it. I had found that even with the S/w screen lock, you could do things to the unit like flash a different ROM (but of course it would not boot up - still on S/W screen)..

If you do not have CMW, then go to the One-click recovery thread and follow the instructions there - especially the installation of the PX drivers. Even when I could no longer connect with the battery in through USB, I could use NVflash.

Select external SD mode. Then you can flash the ROM you put on it. It should indicate a successful ROM flash, but it will still be stuck on the S/W screen.

After flashing the Stock froyo ROM (assuming you get this far), I would use the recovery tool again to put the stock Recovery back on. This is what they might notice first, as pushing the vol. down/power on buttons will quickly show what recovery is on it.
[T-Mobile LG G2x] JosephSmith000:
Ok i am a complete noob at this as this is my first android phone.

Is this thread you're referring to?

http://xdaforums.com/showthread.php?t=1056847

Ok so first I'm supposed to follow the instructions on "Nvidia NvFlash APX Driver", right?

Also That doesn't have instructions on how to flash stock Froyo, just stock recovery. Sorry for asking for these dumb questions, but can somebody give a detail list of steps to do?
[T-Mobile LG G2x] gaww:
You are almost there - that is the tool.

1. Flash APX drivers.

2. run the Recovery tool, and select the External SD option.

3. Download the stock froyo ROM (labeled thread in Dev. Section) and copy to your SD card.

4. Open your new Recovery (vol down/power button at same time.

5. Select install zip from SD card, and find the stock ROM.zip where you copied it to in 3. above and flash it. Don't worry about wiping anything first - you will not actually be able to use it, as you are stuck in S/W screen.

6. If all the above has been done, then run the recovery tool again and load stock Recovery.

You are now ready to return the phone.

Again - probably just loading the Stock Recovery might be enough. If you never flashed a new recovery, you might be OK as is if you are still stuck in the S/W LG Loader screen (?)
[T-Mobile LG G2x] JosephSmith000:
Thank you so much for this. I will give this a go once I get my phone back from the store. Much appreciate!
[T-Mobile LG G2x] gaww:
One thing I have noticed with my LG Updater phones was in addition to a messed up baseband, for some reason the IMEI number in settings/about also was wiped. As a result, when trying to restore it, at times the LG Updater would go into emergency mode and ask for serial and IMEI numbers. It would then indicate "fatal error".

My guess is that because of the wiped IMEI, it could not proceed past a certain point where it looked for the number. If your is similarly gone - I believe you will also not be able to recover it.
[T-Mobile LG G2x] JosephSmith000:
Crap, so what happens if that is the case? I thought I wouldn't be using lg updater to restore..

I'm getting my phone back today, so I have yet to try it.
[T-Mobile LG G2x] JosephSmith000:
ok i think my phone's restored to stock recovery move. i did not, however, restore to stock froyo because my sd card is missing. calling the store again to find out what the heck happened to that.

it happened quite fast, it only took about 2 seconds, and the last message said something about stock img successfully sent. so is that it? is my phone in stock recovery mode? and yes, i am still stuck on s/w upgrade. that's a good thing, right?
[T-Mobile LG G2x] gaww:
I think you are ready for a replacement phone from TMo (do not go after one from LG) . Tell TMo that you are stuck in the S/W screen, and that the local store tried to work on it and could not free it up. You will probably now end up with a replacement device that already has the new GB ROM and the updated baseband.

Tell then all the time you have spent and they might overnight it to you like they did mine - got it the next day.
[T-Mobile LG G2x] JosephSmith000:
Does the phones get sent back to lg eventually? They already ordered a replacement for me.
[T-Mobile LG G2x] konflikt1911:
ugh this sucks!!! I didnt get my g2x from tmobile I traded my atrix for it I wonder if I call them would they help me. the only computer i know of in the world with xp is my work computer which im on now and i have no admin privildges so i cant install anything on it to fix it :(
[T-Mobile LG G2x] konflikt1911:
did you get your g2x from tmobile?
[T-Mobile LG G2x] JosephSmith000:
I bought it at a tmobile store, so I guess.
[T-Mobile LG G2x] JosephSmith000:
Sell it on eBay and get some cash back at least.
[T-Mobile LG G2x] konflikt1911:
thank heavens i dont have to. Just got off the phone with tmobile and it was covered somehow they knew i had one even though i signed my contract with a mytouch 4g. They are overnighting it out to me, ill have it tomorrow. Then I will be sending back the defective phone :D:cool:
[T-Mobile LG G2x] JosephSmith000:
Just wanted to confirm that I'm in stock recovery mode. When I put the battery in, and pressed the power + down vol buttons, I get this picture except that there's no text on the bottom, but instead a progress bar. then it just goes back to the s/w upgrade.

http://lh6.ggpht.com/5SmyeRE-C_vgq_...f9kjwt20ydMEDwTrJrIXZ6szMjuuaV_5uFDINg=s128-c
[T-Mobile LG G2x] gaww:
I would suggest you call TMo and try.

I had gotten mine from them, but have gotten two replacements without having to prove that I bought it from them (they only asked for SN and IMEI). They are very away of the LG Updater - stuck on S/W screen issue and nave been very fast in supplying a replacement.
[T-Mobile LG G2x] gaww:
If it is the box with the yellow arrow - yes. You can do what you did above again, but when you get that screen (picture with progress bar), press the home button and it should then do a factory reset wipe and then open up the blue text stock Recovery screen.

It may not respond to reboot - so just pull the battery. But this means you have stock Recovery and you have wiped your device.
[T-Mobile LG G2x] JosephSmith000:
Well the arrow looks more orange than yellow if that makes a difference. I pressed the home button, and selected factory reset then it says formatting cache and data, and the screen goes to the same picture above but with no progress bar or text. It is also stuck on that screen. Is that what it's supposed to happen?
[T-Mobile LG G2x] gaww:
It sounds like you have a messed up stock Recovery - so you are OK.

Just get a replacement now from TMo. It will probable come with GB 2.3.3 on it and the new July baseband. They send it in a box with a return paid UPS sticker for sending your old unit back.
[T-Mobile LG G2x] JosephSmith000:
Got my replacement last night with gb installed :)

Thank you for saving my ass!

update: i flashed stock recovery on my phone again, put the battery back in, and pressed the power + down volume buttons. the same picture/screen appears, and when i pressed the home button, something different happens: it first says formatting cache, data, and misc. finally the blue text screen appears with all those options. when i select reboot, it just goes to the same android and the box picture but nothing happens.

That sounds more like what you originally described, so hopefully my phone is now wiped.
[T-Mobile LG G2x] gaww:
You have stock recovery, and it is wiped. Put it on the return box (make a copy of the label/tracking number just in case) and wave goodby.

Now you can put CMW recovery on your new one, and you will be able to make nandroids and restore them without root. If you want root, flash the rooted stock 2.3.3 ROM from the development thread before you load a lot of apps, as it erases most of them. Then you can install apps like titanium backup (which needs root) and also make backups of your installed apps.

Good luck and happy flashing. And always make fresh nandroids (at some pint you can erase the old ones) every time before you step out to a new ROM and/or kernel.

Virtual Machine works, too

Just wanted everyone to know that a VM of Win XP will work, too! Just did it with mine via VirtualBox (running Win 7 x64).
[T-Mobile LG G2x] JosephSmith000:
Thanks for all the advice. Just spending time playing with the new firmware then I'll flash CMW. So glad this nightmare is over!
[T-Mobile LG G2x] PseudoChris:
I spent hours trying to get this to work on Win7 or XP Mode and I'm pretty sure its impossible with those (as the post states).

However, I purchased my G2x (via upgrade @ Costco) and aside from the $79.99 (after T-Mo MIR) they were also willing to replace my phone after it bricked on the LG update.

I followed the steps on the LG site for updating this time around and it was flawless.

But before heading to Costco, I contacted LG and they said they'd replace it. (you just need to pay for shipping to return your phone)

Basically, if you don't have XP. Just exchange it via manufacturer warranty or retail warranty wherever it was purchased. It will save you a lot of time and effort.

why is this for?

Hello Guys,

I just connected my phone to system and the lg update tool said there was an update(gb ofcourse i believe). But before i did any thing i checked out the forum and i found this thread. So the bricking during GB update happening when we update via software tool itself or is it for specific phone (i.e. rooted, etc). Btw mine is just rooted via one click method, nothing more. Any confirmation is appreciated as i wanted to update it. Thanks once again
[T-Mobile LG G2x] jboxer:
Unroot your phone first and remove all root programs before running the update. Since the update unroots it you don't want apps you cannot use stuck in your system partition.

Then close down all running programs on your computer and disable any anti-virus programs and your firewall.

Run the LG Updater and install the drivers via the updater program to make sure you have the most up to date drivers.

Then when it returns to the updater plug your G2X into your computer and let all the drivers install (about ten or so) before proceeding.

Then when the updater tells you the update is available click start update.

The program will then download the update. This will take a while.

After the update is download and validated the update will beging and your phone will reboot into Software Update mode at 4%.

When your phone reboots into software update mode another drivers will be installed. This is the first point the update might fail. On mine it did and it told me to remove the battery, etc, but instead I just unplugged the phone and plugged it back in, and then told the updater to restart. I was lucky and it proceeded to work.

The update resets the usb connection on the phone three times. Your computer will beep and the phone will reconnect to the computer. The approximate spots are 46% and 76% (goes back to 75% after it reconnects). This is normal and just let the updater do its thing.

If at any time it tells you to remove the cable, battery, reinsert the battery and turn on the phone, try to simply unplug the usb cable and plug it back in and click restart update first. If that doesn't work then do the battery pull as suggested.

If you phone is stock and you follow these instructions, your phone should update with no problems. If it does get soft-bricked there is a guide on this forum to get the update to flash but at that point you can only use Windows XP SP1 or 2.
[T-Mobile LG G2x] daenris:
So, I suspect my phone is beyond help at this point, but thought I'd check before replacing it.

Like a month ago I performed the LG update and everything went fine and I've been running GB since then. A few days ago, the phone locked up and was unresponsive to any buttons, so I had to pull the battery. After that, I was unable to get it to start at all. I suspected maybe it was overheated so I let it sit for awhile. Eventually I was able to start it back up, but after another 15 minutes or so it locked up again. After that, it would not start for several days. I was on vacation so couldn't do any further digging.

I got back from vacation last night and immediately started following the steps from the OP in this thread. The phone will still be recognized by my computer in APX mode. At first, everything went fine and the one-click recovery seemed to work. At that point, as indicated in the original post, I was able to boot back into the existing system at that point.

Unfortunately, after about a half hour it again locked up and I had to pull the battery. The phone is still recognized by my computer in APX mode, but every time I try to run the one-click recovery it hangs at the "waiting for booloader to initialize" and never proceeds past that point.

Any suggestions on other things to try, or should I just swap out the phone as defective?
[T-Mobile LG G2x] jboxer:
Did you overclock to a high speed for an extended period of time? If it got too hot, that can actually damage the circuits inside the phone.
[T-Mobile LG G2x] daenris:
Nope. No overclocking or anything. The phone was completely stock, and then updated with the official LG gingerbread update.

In any case, I eventually gave up yesterday and went to get a replacement phone since I couldn't even attempt to use nvflash to recover mine since it wouldn't get past "waiting for bootloader to initialize."

I HAD WIN 7 and it worked through the above method!!
[T-Mobile LG G2x] brian_desmond:
I tried to "unbrick" my G2X for literally 3 days straight using this method...

Right when I was about to give up for good it dawned on me that the LG Modem driver in Device Manager may have been conflicting with the USB driver thus causing the KDZ to be unsuccessful resulting in the dreaded "PHONE NOT FOUND" message...

I simply disabled the LG Modem driver in Device Manager, reconnected my phone, and the KDZ worked and 5 minutes later I was snackin' on some Gingerbread.

If you can't seem to get any result other than "PHONE NOT FOUND" when running the KDZ try disabling that LG Modem driver in DM. That could be your problem.

I really hope that anyone still experiencing the SW UPGRADE issue gets it resolved, I felt your pain for 72 hours straight, you can do it!
[T-Mobile LG G2x] Gryncc:
So there is no way at all to upgrade it on win7
[T-Mobile LG G2x] jboxer:
If you are not in a soft-brick situation you can use LG Updater with Windows 7. If you need this procedure to fix a soft-brick then it is recommended you do it on a Windows XP machine. Some people have reported success using a virtual Windows XP session in Windows 7. The software to run Windows XP within Windows 7 is free from the Microsoft website for free.

The GB release with July 15 baseband are official LG and TMO releases so there is no reason to downgrade the baseband for RMA purposes. Just flash everything back to GB 2.3.3 stock and you are good to go. They expect phones to be updated to GB.
