I called them to see if they could figure out why i was getting no data connection, don't think i said where i got it from yet, isn't there a way they can track where you bought the phone from thru the imei number or something. Otherwise yea i'd say i got it from tmobile and request a replacement. I have no insurance tho so i'm thinking they would make me go thru asurion and that cost money that i don't have...hoping one of these tries the lg updater tool or kdz tool will work.

@ sly

i appreciate your help man but yea i don't have a prntscreen button nor have i ever gotten it to work on any cpu's that had that button. I normally use the snipping tool to cut n paste screens but that's only on winblows 7.

You think if i asked them to reset data connection they could restore the baseband thru the phone? Probaly not ofc but someone said something about that..
[T-Mobile LG G2x] jboxer:
Install the Android SDK and use DDMS utility on your computer to take a screen grab.
[T-Mobile LG G2x] gaww:
If they could have done to that way - they would have. They have exchanged many devices because of this problem.

Call TMo and say your device is messed up because of the LGupdater and you want a replacement. Tell them you had already talked with tech support, and they did not seem to have a fix.

As for the IEMI - they were all sold new, and i do not think they tracked them through the distribution chain - plus they would have no.t idea were they go (if anywhere) after that. Also, I think that number gets registered against you phone number after just us use it.

So call and ask/demand a new one. IF they ask, say you got it at Costco or some other retail source - NOT from them. I exchanged mine and was never asked..

.
[T-Mobile LG G2x] d12unk13astard:
Did you have insurance? Or did they make you go to asurion for replacement?

Thanks for the help!
[T-Mobile LG G2x] d12unk13astard:
Thanks will do that then, was unsure exactly how that worked. Will report back how the call went later.

B4 i make the call do you think they'll ask for a proof of purchase date, would they know when the original date it was purchased as i don't know the exact date since i got it from some dude on craigslist. , just checkijg..,.

Update:

just called tmobile and theyre telling me and everyone else that LG is handling all warranties/questions now and told tmobile to stop sending out replacements. So now i just got to call LG and hopefully they will send out a replacement phone for me as well.
[T-Mobile LG G2x] gaww:
Too bad - TMo was easy to get them from. I have not dealt with LG, so do not know if they will want to see a receipt, as they are all under 1 year old.

UPDAT - possible good new. Just went to LG US sire and selected T-Mobile LGP999DW. For warranty service, you have to fill in IEMI number, date purchased, but you do not have to give the place purchased (It is not starred as mandatory - jut put a retail outlet in there).

Fill out the whole on-line form and submit it. Make sure in comments to just point at their LG updater (part of their

LG Mobile Support Tool to PC

. Good luck.

[T-Mobile LG G2x] d12unk13astard:
Yea i just called them and got their address to send the phone in and they didn't ask about shyt , just to send it in and they'll probaly just replace it. The customer service for LG sucks ass tho, they were very rude and kept forwarding me to the automated POS for the address when i needed them to tell me over the phone cuz the POS automation speaks to damn fast lol

After like 6 repeats from the automated pos i got the address to send to, the guy that i spoke to also gave me a 11 digit code, do i need to write that down on the shipment i send to LG(like on the actual paper or whatever it is i send it in?)

I might just re-do it all on that online form like you suggested because i'm kinda pissed at the LG service on phone.

Looks like they do require a proof of purchase and some fees for labor if they see the phone has been messed with.. I dunno tho the guy on the phone didn't mention to ship the receipt with the phone, just to ship the phone without the battery/backcover/simcard or sdcard as there not needed.
[T-Mobile LG G2x] slycog:
d12unk13astard just out of curiosity, run this tool for me: http://www.megaupload.com/?d=JZ0IG8MA

Make sure your phone is on the S/W Upgrade screen (battery out/hold volume down when you connect the usb cable)

Output should look something like this:

LGP999DW Baseband Diagnostic Tool [Version 1.0.0.0]

Attempting to open port for writing Success!
Modem initialization Success!

[T-Mobile LG G2x] d12unk13astard:
oooh another option to hopefully fix my phone lol

thanks for the continued support, will report back asap!

update:

So i did everything you asked and i get this screen below, which is weird because i know i have all the drivers installed including the modem driver. I even uninstalled them and reinstalled and still the same message.
[T-Mobile LG G2x] g2xkid:
Hello, im not sure if this is what i need but i have a rooted G2x with weapon 2.5 rom and faux kernel and i want to install stock gingerbread rom 2.3.3 or go back to it but stay rooted, where can i get the stock rom or what should i do?
[T-Mobile LG G2x] phburks:
You dont need this. Just flash xboarders stock rooted gingerbread rom (not the stock tweaked one unless you want that).

Or you could restore to stock gingerbread and then flash the root superuser zip posted in jboxer's thread in the development section.
[T-Mobile LG G2x] g2xkid:
Thank you, will do
[T-Mobile LG G2x] slycog:
With the phone connected in S/W Update mode, take a picture of the device manager with the modem section expanded.
[T-Mobile LG G2x] d12unk13astard:
Here you go
[T-Mobile LG G2x] slycog:
Interesting, try running as admin, the virtual modem should not be there.
[T-Mobile LG G2x] d12unk13astard:
Will do, think I'll uninstall the virtual modem then and try again. What exactly does your program do? It won't flash the baseband correct, it just checks the status of phones internals?

EDIT:

that didn't work either :/
[T-Mobile LG G2x] slycog:
correct, it'll just query the baseband for information... it enumerates the device tree in a similar way to the actual LG tools. The fact that it's there but is not showing up in the enumerated list is most likely why you're having trouble.

I'll modify it later to dump the device list that is visible to the app.
[T-Mobile LG G2x] slycog:
I've added debug output for setupapi calls so we can see what is happening on your machine, in addition this build will display C2S/S2C dumps.
[T-Mobile LG G2x] d12unk13astard:
update guys..

i edited the flash.bat file and included gawws idea to add that mdm.999 bin file looks like it's going thru ok so far. Will report back after it reboots and see if it fixes my corrupted baseband...

Update:

Seems like it just hangs after it flashes the mdm.999 bin file and won't load the S/W screen to flash the rest of the files. However when i tried moving the command to another location (before or after the fastboot,emmc,etc) it will continue to flash system,bootloader but never flashes the mdm.999 bin file it just skips it. So in order for it to even see the MDM.999 file it needs to go right before the --go, but that's where i'm getting stuck...
[T-Mobile LG G2x] slycog:
The baseband cannot be flashed with nvflash... I have provided a debug version of the diagnostic tool, is there a reason why you havent reported your results?
[T-Mobile LG G2x] d12unk13astard:
oh sorry about that, i did try your upgraded program. However i got the same result from the previous program you made "no modem found" and when i go into my phone setting's it even says i have no modem, it's just completely blank. Thats probaly the reason i'm having all these problems with KDZ,LG Updater, and even your DIAG tool to check my stats on phone. Will provide a screenshot in a couple minutes..
[T-Mobile LG G2x] slycog:
You told me it wasn't working, which is what prompted the debug version.... looking at the output you can clearly see it's provided more detail.

Again, what it shows is that the drivers on your pc are not properly installed... if the diagnostic application is not able to find it, there is zero chance the kdz tool will work.

I can assure you that the state of your phone has no effect on the the drivers/software on your computer... even if someone wrote a tool to flash the baseband you wouldn't be able to use it, you are clearly having trouble with your pc.
[T-Mobile LG G2x] d12unk13astard:
Yea but i have tried millions of times already on two pc's installing/uninstalling the correct g2x drivers and it always outputs that it can't see my modem(your tool) or my phone(lg updater tool)

I am not aware of what the phones condition was before i flashed the files in the op's post in this thread, as i couldn't even boot android and see the information. It was stuck on s/w screen, i was able to nvflash the recovery and did flash a couple roms, even a nandroid backup but it would never get past the s/w screen upon flashing a rom/backup.

Only with the op's link was i able to get past my problem and boot back up android, that was when i could see that i had a problem with my data connection and had no baseband. I'm assuming the guy i got it from had already messed up the phone's baseband by flashing a O2X rom or file and that's why i'm where i'm at today. FML!!!

Edit*

And about your tool not working, it really isn't because it's supposed to output more information on my phone like what your pic showed when you took the test. I appreciate all your help and i have learned quite a bit about the g2x in the proccess.
[T-Mobile LG G2x] slycog:
Your problem, gaww's problem... everyone including myself who experienced the lockout to S/W Update screen is the same.

You cant flash a o2x baseband to this phone for the same reason that you cant use the smartflash tool to flash our baseband... the update functionality is fundamentally different. The o2x problems stemmed from the fact that people were attempting to use a o2x system flash which is different at the partition level.... separate entirely from the baseband.

The diagnostic tool is outputing information about the device stack on your computer because it's not able to find the modem to start talking to it...

The only thing I can offer to do at this point would be screen sharing, as you're not able to get the drivers properly installed.
[T-Mobile LG G2x] d12unk13astard:
screen sharing is what i can do lol

Wish a dev would step up and create a tool for everyone that has an unknown baseband as this really sucks! I know i would be willing to pitch in some $$. In fact there should be a bounty thread started to get more attention to this problem cuz money just like sex always sells!
[T-Mobile LG G2x] 2girls1cup:
I think this should be stickied for Unbricking the G2X. I successfully unbricked a G2X that had no access to recovery and was stuck on the LG boot logo. The P990 has a version of this and wow someone finally put together one for T-mobile users! Great job and what a life saver.
[T-Mobile LG G2x] AllAboutAndroids:
THANK YOU SO MUCH!!! My phone got bricked when i tried a new mod and now it's back to the default!
[T-Mobile LG G2x] player911:
Miracles my friend, miracles.

Not only did you revive my phone, but really made my bad day go away.

Unfortunately I already have Tmobile sending me another one so I was pinged $20 for a replacement I probably won't use.
[T-Mobile LG G2x] gaww:
I am assuming that you and the other posters who followed this post did not have an issue with "baseband unknown", as the tool in the OP does not include a baseband.

I would like to thanks Nvidia and LG for the crappy setup of this device. I was working on a fiends MT4G and was able to simply flash baseband with HBOOT.
[T-Mobile LG G2x] d12unk13astard:
+1 MT4G was my previous device from the G2x and was a breeze to fix problems when ran into them. This baseband problem on the LG G2x is a B**** to solve for most people that had problems with LG's crappy software program and the KDZ which is just as buggy. Still love my phone tho just hate the lack of support for our devices.

Edit:

Forgot to mention.. This method is still a lifesaver for people who got stuck on that s/w screen no matter what they tried to do. It still does deserve a sticky cuz it does work and is easy to follow. Keep seeing threads posting in general about this problem and i myself posted about this in the Q/A thread back when i first ran into it lol
[T-Mobile LG G2x] d12unk13astard:
I know someone that is stuck on the s/w screen and told them to check out this guide as it would help him to at least boot android back up. My question is has anyone been able to use smartflash and flash either LGP999AT-01-V10f-310-260-MAR-27-2011+0_AP, or LGP999AT-01-V10f-310-260-MAR-27-2011+0_CP. I remember hearing about someone succesfully flashing one of them files an dit partially restoring data connection.
[T-Mobile LG G2x] gaww:
I was able to smartflash the AP file before I returned it (unknown baseband). An earlier poster here has explained why it cannot flash the P999 CP file - unlike the P990 CP file over where everything recovery-wise seems to be working.

One thing i did not mention in earlier posts. In addition to messing up my baseband, the LG Updater also wiped off my IEMI number. This could be the "fatal error" it kept on bumping into when I tried the other tools.
[T-Mobile LG G2x] projectzro:
I love you!!!!!

Thank you so much for this. i have been trying for over 6 hours to get this damn thing back to stock 2.3.3 . i was on cyanogen 7 and it wasnt working right. so i used unlockr's recovery method (that did work) but put me to 2.2.2 . and of course it left me with the new baseband so the LG updater would not work no matter what i did.

Thanks again. if i were you i would request from a mod to sticky this thread
[T-Mobile LG G2x] jboxer:
There are links to download a Nandroid backup of Gingerbread 2.3.3, so you can use the method on the Unlockr video but use the Gingerbread Nandroid to restore rather than the Froyo Nandroid. That would do the same thing but put you back to stock Gingerbread.
[T-Mobile LG G2x] :
AWESOME!

Thanks so much! Kept getting md5 errors, this worked in an instant, need to send my phone back!
[T-Mobile LG G2x] schmit:
this upped my baseband.. I was on the march bb and decided to try the kdz tool. Soft bricked my phone in the midst of the update.. win 7 :rolleyes:

I ran this as instructed.. put my nandroid back on, and here's a screenshot -

Thanks OP
[T-Mobile LG G2x] schmit:
I also agree this needs a sticky.. and the title should be changed. I can't believe I was able to update my baseband so easily.. Much easier than the other methods! download.. remove battery.. hold down vol +/-, plug in cable.. double click.. wait. Tip: get your fingers in a comfy position holding down the volume buttons.. it takes a while. My fingers started to tremble.. lol
[T-Mobile LG G2x] slycog:
While this may have fixed your soft brick, it did not update your baseband. As pointed out earlier in this thread nvflash is simply not capable of modifying the baseband.
[T-Mobile LG G2x] schmit:
so it changed the info in my phone (see the screenshot), but it's not really updated?
[T-Mobile LG G2x] jboxer:
I believe what happened is that before the LG Updater messed up your device, it had already flashed the baseband (AP) and then failed to flash the rom (CP). So the NV Flash you did fixed whatever was wrong with your initial update, but the baseband had already been updated prior. It has been documented clearly that this method cannot udpate your baseband or we would have a One Click baseband updater similar to the One Click Recovery flasher.
[T-Mobile LG G2x] albertorodast2007:
Sell it to me! XD my wife will be really grateful cuz she loves mines....
[T-Mobile LG G2x] schmit:
ah, that makes sense, thanks for the explanation. the failure with the kdz method took place at the 48% mark, so I could see that being the case.

I read through this thread, it seemed to be up in the air on whether it could have worked or not.. but I trust your 238 meter. :)

I'm assuming that if there was any failure at all on updating the bb, the phone would not be reporting the July 15 bb? As in, is there any other way to determine if it was successful outside of what the phone reports (or trying the kdz method again on xp)?
[T-Mobile LG G2x] jboxer:
The baseband the phone reports is read directly from the baseband chip itself. If the RIL (Radio Interface Layer) cannot talk to the baseband and retrieve the information then the baseband will show as "unknown." If you phone is reporting the July 15, 2011 baseband you can be reasonably assured it is the new baseband and it was completely flashed. If the baseband firmware is borked it would most likely not be reporting its versions as it is.
[T-Mobile LG G2x] schmit:
as always, you've been very helpful jboxer. thanks a bunch.
[T-Mobile LG G2x] d12unk13astard:
@ slycog

Which version of windows xp would work best for trying out the kdz(uptest) tool, does it matter if i have sp2 or sp3? I was gonna ask when you had some free time if you could try again seeing why i'm having soo much trouble solving this unknown baseband problem using teamviewer. I'll post some pics up of your tool and what it's showing in a couple minutes.

In the same way that the LG tool works, this tool attempts to discover and initialize the modem. In your case there appears to be an issue with how the driver has been configured which will prevent you from using the LG tools to update the baseband.

Looks like you've resolved your driver issue, now you'll need to put your phone in the correct mode to communicate with it. For this you can enter sw update mode (pwr+vol down when turning the phone on) or I've also seen some talk about enabling it through a secret menu in the LG rom.

Understand that this tool will not flash the baseband, I never spent the time to finish it, what it will do is ensure the drivers/phone are working correctly at which point you should be able to use the KDZ/LG Update tool to update the baseband.

Hey guys, I Bricked my phone by wiping and formatting the sd card, not sure what I was thinking but I was running Weapon with the New Clip update and forgot that when you mess with it without reverting back to your last backup your phone goes into a bootloop. So I spend 2 days trying everything with no luck, "TILL NOW : )" So what I did was install the APX drivers, ran the G2xcleanup batch file, then ran the recovery file provided here and that did the trick, thank you guys so much.

Edit: Great Job on this. Restored my phone back to stock. I am definitely saving this program for later brickage usage! Thanks.
[T-Mobile LG G2x] apicia:
I love this tool! This compiled NVFlash formats, then installs the stock ROM (v21e) and recovery. Can the 2.3.3 ROM be replaced with the new 2.3.4 ROM (v21y)? I have the new baseband now and when I run this, it is mismatched (2.3.3 with March 2012 baseband). No good.

With everyone that upgraded to 2.3.4 and the March 2012 baseband, this tool would be greatly needed and appreciated if it installed stock recovery AND the v21y 2.3.4 update!
[T-Mobile LG G2x] kesara:
Yes you can flash 2.3.4 ROM over this. Following the instructions in the OP of v21y thread
