[T-Mobile LG G2x] mmapcpro:
I just did this. I'm on a windows 7 64bit pc. I updated to GB only to obtain the baseband, then intended to restore my CM7. These are the steps I took:

1) Nandroid my cm7 nightly

2) Restore to stock using TGA_Gunnman's nandroid and wiped data/factory reset immediately AFTER restoring stock, and prior to turning phone back on

3) Turned phone on, skipped google login

4) Enabled Debugging mode and then unrooted with superoneclick (I know some people say this isn't necessary, but since installing the update was going to unroot my phone anyway, I didn't see the harm in taking this 30 second step.)

5) Turned phone off and pulled out the battery

6) Started up nvflash (I already had the APX drivers installed...if you don't already, you need to follow the instructions on this thread:

7) Pressed and held volume up and down keys simultaneously, waiting a few more seconds and then plugged in USB cable (USB cable was already connected to PC's USB port)

8) Selected "Flash Stock Recovery" and continued to hold the volume keys down until the flash completed and said "press any key to continue"

9) Pulled out USB cable, released volume keys, re-inserted battery, and booted up, again skipping google login

9a) Increased screen time-out duration to 30 minutes because it was annoying me everytime it would go dim after 30 seconds, lol

10) Plugged in USB cable to my phone and followed the steps in the OP exactly (installing msxml.msi FIRST before the kdz tool).

11) Update tool turned phone on for the first time (update process took 5 minutes) and then I exited the LG software and KDZ tools once boot up was 100% complete.

12) Repeated the above steps 5, 6, and 7 but this time I selected "Flash Clockworkmod External support"

13) NVflash didn't recognize my phone, probably because I plugged it in too fast after pulling the battery. So I pulled out the usb cable, waiting 30 seconds, then pressed and held the volume keys for 5 seconds, then plugged USB back in and selected the flash option again. This worked.

14) Pulled out the USB cable, released the volume keys, re-inserted the battery, and booted into CWM by pressing and holding the volume down button and power button simultaneously until the 2nd splash screen appeared (ANDROID in green letters).

15) Restored my CM7 nandroid and fixed permissions (not sure if this is necessary, but it's become a habit of mine).

16) Booted up and took screenshot.

17) Plugged in USB cable and wiped internal SD of all stock android installed stuff.

End result: Successful baseband update with preferred CM7 environment.

edit: test gps and it got lock, accurate to 36 feet within 12 seconds (which is a personal record for this phone and this area)...it took about another minute or so to get it accurate to 9-12 feet. I don't know about this 'instant lock indoors" thing I kept seeing people post...I waited about 2 minutes for lock indoors and I finally stopped caring.

Thank you so much OP!
[T-Mobile LG G2x] Pecata:
Yes, it worked. Thanks so much! The LED notification app doesn't work on it without root and the camera app kind of sucks, but otherwise it is nice to finally have Gingerbread.

Thanks again!

Whats up all! My first post but I've been the game since my beloved G1. Update went perfectly on my dwp g2x. Thanks for this method because my nandroid backup/rooted version was good but didn't feel complete without the baseband. Soo far i have no complaints with this update.

When i tried the fix in XP mode still got stuck(crashed) for some reason. So i downloaded VMware Workstation installed XP SP2 and bam update went through.But i didn't go to the the other options you did I just loaded file and clicked launch software update and was stuck on those 2 lines and waited then it went through.Thanks.

Running win7. I have followed the instructions for installation of software and no joy. Here's my step by step.

Installed msxml.msi

run KDZ software

browse and pick v21e_00.kdz file

click on read phone info

click upgrade start

lg software lunches and it gets to the a 100 percent uncompressed and indicating to not disconnect usb cable and battery until upgrade is complete then the software crashes

I've tried to run it under compatibility mode for win xp pack 2 and 3 with the same results. I have also run it as an administrator and no luck.

What gives?
[T-Mobile LG G2x] JJDolfan92:
Same Exact thing happens to me. I tired on both Windows 7, and an XP Machine I have aswell and still it crashes when it gets to the Download part. Where it tells you to not disconnect your phone or whatnot. Is there a fix because this is SUPER Frustrating, and my phone is stuck in S/W Mode I Can't do ANYTHING right now.

[T-Mobile LG G2x] ciscojmd:
From what I was told by tech support tier 2/3 on Sunday morning. This LG update wasn't supported by T-Mobile, it was only supported by LG. Per the conversation and many questions asked, if anything goes wrong it voids your warranty with TMo. Not with LG since it was their software. From what he said, in no way was this "the official way" of an update for Tmo...
[T-Mobile LG G2x] laratasucia:
yes lg updater software was installed. As I mentioned, once I run the KDZ software and browse for the file and hit update, lg updater launches and goes thru all the way until it warns you to not disconnect the usb cable or the battery.....
[T-Mobile LG G2x] JJDolfan92:
Same, I have done everything just like him. I am having the same issue aswell.
[T-Mobile LG G2x] swuln:
Did you download the latest LG updater ...I believe they updated the drivers... That's what I did cause I read somewhere it needed to be updated.. I myself had no problems at all...
[T-Mobile LG G2x] swuln:
I was also running windows 7 ultimate 32 bit...
[T-Mobile LG G2x] swuln:
Don't know if its been mentioned but I also shut down any other Apps running like antivirus things like that.. You could also try a different USB port...

Frustration IV

Running win7. I have followed the instructions for installation of software and no joy. Here's my step by step.

Installed msxml.msi

run KDZ software

browse and pick v21e_00.kdz file

click on read phone info

click upgrade start

lg software lunches and it gets to the a 100 percent uncompressed and indicating to not disconnect usb cable and battery until upgrade is complete then the software crashes

I've tried to run it under compatibility mode for win xp pack 2 and 3 with the same results. I have also run it as an administrator and no luck.

yes lg updater software was installed. As I mentioned, once I run the KDZ software and browse for the file and hit update, lg updater launches and goes thru all the way until it warns you to not disconnect the usb cable or the battery.....

Another update to my freaking atemp to get this phone back to life.

I have tried the procedures described above in a laptop running xp sp 2 and now the lg software get stock at 30 percent after i lunch the KDZ program.

I have tried it multiple times and on different usb ports. I also made sure that the modem and the serial ports are different under the device manager to avoid conflict between the two.

I have restarted my laptop everytime i try it again.

I am ran out of ideas.....
[T-Mobile LG G2x] Scyth3:
Are you using the stock recovery? And was the OS the stock 2.2 release?
[T-Mobile LG G2x] laratasucia:
I've done stock recovery and clockworkmod as well.

The phone had the v10f update and was rooted.
[T-Mobile LG G2x] laratasucia:
I had that problem when i was trying to install the tool on a win xp machine.

I was able to fix the problem once I installed sp 2 .net framework.

Not sure if that applies to win 7 machines.
[T-Mobile LG G2x] SL:
If one has root the phone and installed CWM, most of the files, drivers that are needed is there.

I find the instructions pretty clear if someone has done the above.

I did it on Windows 7 and have no problems whatsoever

MAKE SURE YOU DOWNLOAD LG UPDATER program and it will install all the drivers from LG - B2CAppSetup.exe
[T-Mobile LG G2x] jcboiz:
Hello!!! Will this in any way void an warranties with either LG or T-Mobile? Thank you in advance...

+1 for this, stupid LG tool froze every time I used the "Read Phone Info" button. Had to use XP and the "Launch software update", even that took 4 tries.
[T-Mobile LG G2x] laratasucia:
Im afraid i have tried this as well and the kdz tool crashes after the second log entry. I think it says unpacking .kdz file.

Im starting to believe i might have donwloaded a bad file or something like that.

Ill update after i try.

Im running win 7 sp 1
[T-Mobile LG G2x] laratasucia:
Ok making some progress here.

I donwloaded the KDZ update tool again and I was able to get pass the unpacking .kdz file but it crashes right before the installing process.

I also noticed that if I run the program as an administrator it crashes when it tries to unpack the .kdz. I have also tried to run it under compatibility mode under xp sp 2 and 3 with the same results.

This is all if I just run the KDZ tool and not through the lg update tool.

If I try to do the update tool, the results are the same. It get to the point where it reads to not unplug the usb or battery and then it crashes.

So close.... I can taste it
[T-Mobile LG G2x] Scyth3:
Did you install msxml?
[T-Mobile LG G2x] laratasucia:
Correct me if am wrong, but once installed it doesn't need to be done again.
[T-Mobile LG G2x] Scyth3:
Correct -- but you should also reboot the computer if you just did a fresh install of it.
[T-Mobile LG G2x] erikiksaz:
did you install net framework 3.5?

Congratulations to all that have used tool this and succeeded. I have not had any such success.

My problem when the LG Upgrader first failed and also now is a "fatal error - cannot proceed with the update" message. There apparently is no way around it. have tried W7 and XP machines, but same results.
[T-Mobile LG G2x] laratasucia:
I am on the same page.

I have tried procedures using just the KDZ tool and the one using KDZ and the LG updater tool and I am still stuck with a phone that says S/W update.

For those that were lucky enough to get any procedure to work, can you be more specific than to mention "it work for me" or "it took only 5 1/2 mins" to help others still working on this problem.

Thanks

[T-Mobile LG G2x] laratasucia:
This is the last few lines of the log for the LG updater tool after it launches from the KDZ tool. Unfortunately I am unable to post the whole log as the program is unresponsive.
[T-Mobile LG G2x] gaww:
Did your log show a line containing the "encountered fatal error - cannot continue the upgrade..." ? If not, there is still hope for you with this procedure.

I got out of the S/W screen another way, but it ended up leaving me without a baseband, and neither XDA nor modeco.com have a procedure to handle that.

I used Paul's "disaster recovery" process to flash a 990 ROM. It works great, but besides flashing the ROM (and baseband), it re-partitions the G2X like a 990.

Step two was to use SmartFlash to flash the LG999 firmware (not the ROM), which would have restored everything except one issue. You want to flash both the CP.bin and AP.bin files. It flashed the larger AP.bin by itself fine, but would not do the CP.bin - which I believe has the baseband. I ended up with the partitions and ROM restored to stock, but no working baseband.

If I could do it over again, I would go straight to Smartflash and try just flashing the AP.bin file. This may free up your device. But if the LG Updater messed up your baseband, then you will not have network connectivity.

Again - if you have not run into the "fatal error" message - I would continue to try using the tool you have been using. I actually got the furthest by opening the "read device info" at the lower left of the main screen, and then telling it to start the upgrade from the next screen. Give that a try if you have not done so yet.

It is official. I have given up....

This is the first time an electronic piece of equipment has beaten me. I am not proud of this situation.

I have just called T-mobile and they will be replacing my phone by tomorrow. (that's what I call customer service... Sprint, At&t has a lot to learn from this company)

I wish good luck to those still out there trying to figure out this problem.
[T-Mobile LG G2x] jdaclutch:
That's what I did 10 mins ago, my replacement is on the way. Hoping that my new g2x will have the new leak/fake official gb with new baseband on it.
[T-Mobile LG G2x] gaww:
I am in same boat. I have the replacement and had to return original before deadline.

I do not know if you could tweak the O2X disaster recovery to avoid it flashing new baseband. It may not help in any case, as I think the LG Upgrader corrupted the G2X baseband, and there is no way currently to restore the G2X baseband - period!
[T-Mobile LG G2x] gaww:
I doubt it will, but if so, open a new thread in "general" to let everyone know.

G2X Stuck in S/W upgrade screen

I tried the method mentioned in the OP for my lgp999dwp on a PC running Windows Vista. At 4% update it gave me an error message popup- something about the file device location. The only option was to press "OK". AFTER that, the software told me to remove the cable, battery and then reconnect them. It repeated the same thing 3 or 4 times before telling me to call customer service. Now the phone is stuck in the S/W update screen. A master Reset didn't help either. Please help me!

A Note for Canadians on WIND

Works perfectly.

Just a note for Canadians who are being directed here from the WIND forums - this process works perfectly but makes your formerly WIND branded phone a "T-Mobile" branded phone running on a "4G" network and installs a load of bloatware as well.

It's interesting to note that Canada's WIND digital 3G network is apparently the T-Mobile's "4G" - really?
[T-Mobile LG G2x] phburks:
My understanding is that T-Mobile markets their HSPA+ network as 4G based more on how its network speeds compare to other wireless operators here in the USA, rather than on whether the technology is truly 4G or not. It seems to be up for debate what truly constitutes a 4G network. It makes no difference to me though. As an end user all I care about is how my phone works and how fast my network speeds are. They can call it whatever they want.

[T-Mobile LG G2x] coreycollins3066:
I had a stock Froyo 2.2.2, not rooted. I used the LG update tool since it was listed on T-Mobile's website. I assumed it was the T-Mobile approved update since T-Mobile OTA update is already complete.

After running the update, completely through to 100% complete, the phone restarted. After it restarted, it doesn't recognize the SIM card and has a ? for the battery. In the settings, it doesn't list a baseband and doesn't have a IMEI number. The LG updater tool blows.

I am going to try the method using the KDZ tool and V21E file tonight. Hopefully I can get GB to work.
[T-Mobile LG G2x] jboxer:
You sure you have a G2X and not an O2X? Use KDZ method to reflash if you have G2X.
[T-Mobile LG G2x] Sei911:
Thank for this great post. This will come handy one day.
[T-Mobile LG G2x] coreycollins3066:
If this was directed towards me. Yes, it is a G2x LG999DW T-Mobile.

Everything went through fine with no errors. I loaded the drivers, WIN7 32bit recognized the phone and installed the drivers. The LG update tool didn't have any errors. I downloaded and installed 2.3.3 with no issues. It said the process was complete and the phone restarted.

That is why I'm confused on how I ended up with 2.3.3 with no BASEBAND and a question mark on the battery icon. It looked as if the update worked perfectly. So now, I'm going to run the KDZ program and see if that works. I'll try it first in WIN7, then XP through VMWARE if WIN7 doesn't work. If that fails, I'll repartition my drive and boot up XP.

I feel you... I'm in the EXACT same boat. Did a 100% "successful" update, reboot the phone and NO baseband and ??? and 999 for battery level.

has there been a fix for this yet?

any help will be appreciated i hate using my back up phone :(
[T-Mobile LG G2x] gaww:
I was in your boat, and ended swapping out my phone (after flashing stock recovery back).

There is not a new tool on the Dev section that i would have loved to have tried back before i returned my phone. If you are still bricked, i would give it a try. It is done with NVflasher, and would restore your phone with the updated ROM and possibly baseband (which is what you need).

It is not certain that this will work in all instances, but that is what we are trying to determine. It's fixing a few more bricked phones and posting results would benefit all.
[T-Mobile LG G2x] bmann_420:
Theirs also a new method in the dev section with all files needed if you've totally corrupted your phone. I'd give a link but I'm on my phone =\ but if all else fails, after reading that thread, I would definitely try it.

slycogg knows his stuff and i believe him when he says *nvflash* method will not restore baseband on the g2x.
