welcome to XDA- I would say try it with out root. you could CWM a the unrooted stock 2.3.3 that was origanly posted by xboarder56. i am not sure if it is still being hosted. I just achived it myself. most custom 2.3.3 are rooted. as far as i can tell you just need to be on a 2.3.3 rom that is like or near stock like Eaglesblood 1.09(?) or weapons. The best thing i can tell you is read read and search. then when you think you know it re-read. ;) i am still new to this and it was not a walk in the park.

ok I am itching to run this but want to donate my knoledge to every one before playing and forgetting.

i did this on P4m 2.66 with 1.25g ram. windows xp pro 32 bit sp3 (fresh install). (dell inspiron 5150)

no antivirus. windows firewall off. Downloaded the .kdz file (thank you overground) and the KDW tool ( http://xdaforums.com/showthread.php?t=1287236 [thank you adixtra]) follow most of that guide. along with this thread. the setting that worked for me was CDMA and DIAG. ( started to get pissed and was pushing any thing) ran the upgrade using the upgrade button just below where you load the .KDZ file....ok i am done. i will be back later...first thaks to the OG's sticking around kwes, jboxer and core memory. ( one day i hope to as smart as you :D) OP thank you as well for starting this thread. I will try to stick around in here to help people out. ;)

I'm afraid I might brick the phone.

I think I know how to unroot its just

The procedures that confuse me.

[T-Mobile LG G2x] nickcuban:
This is driving me up the freaking wall. Once every other day or so it tells me that the OTA is available and somewhere along the way it has a problem and stops. So I have tried on several different occasons to get the updater way for it to work and it NEVER gets past hitting update now. EVERY time it opens the LG updater and says no update needed. I have followed the directions over and over with no luck. This seriously makes me want to sell this damned phone and buy the Nexus... or even go back to the POS known as the Motorola Cliq. That phone sucked, but at least it didn't freeze all the time.
[T-Mobile LG G2x] DupleX01:
It's	LG update tool issue. It's forcing to update itself to prevent using Kdz method. However, can be deceived using a fake server.

Please, follow the instructions in this thread to setup the fake server, then use the regular Kdz method. Will work like a charm even on Windows7.	Make sure when you start the Kdz, select your preferred kdz file, then "read phone information" and on the popup choose "start upgrade".

My antivirus is telling me that I am installing a trojan with this method...
[T-Mobile LG G2x] Rafase282:
Then let the trojan fix your phone
[T-Mobile LG G2x] DupleX01:
Your antivirus is somehow right, it's traffic hijack. However, it is necessary to prevent LG tool from communicating with its servers. A soon as you have done fixing your phone, just go ahead and remove it. In addition you can check the source codes of the tool as well, if you are paranoid.
[T-Mobile LG G2x] alias503:
I can say it will work. It is pain. Every thing in the last few post are corect about the antivirus preventing the updating to happen. There are so many small variables in any type of program that can cause it not to work. Even them endless little mico$oft updates screw stuff up. Keep at it. It will go through. If you can use a XP standalone 32 bit. I know that works.

Sent from a phone... do you really need to know more?
[T-Mobile LG G2x] gpmartinson:
thanks

I did install it withthe hijack method. Took several tries and eventually got it to download and install. Unfortunately, there is no way I can recreate this process without trial and error and error and error. Lovein the new baseband and am hopeful that devs will hop on the new platform too.
[T-Mobile LG G2x] DupleX01:
Glad to hear that it worked!

Yeah, let's hope the best.
[T-Mobile LG G2x] mzsurvey2000:
Just as an FYI.....I was stuck with the same problem as you.....it would get past the T-Mo G2X screen, get to the LG screen, then bootloop between a blank screen and the G2X screen. (This was after doing the above method that you mentioned.)

To get out of the bootloop, I did a battery pull. Then I pressed Vol-Down and Power and held it until I got the "Android + Box" screen. Then it loaded fine. That helped to restore the phone to the OS. Then I reflashed the kdz using the methods described at the beginning of this post. I now have 2.3.4 on my wife's phone and it has been working fine so far!

Hope that helps.

another success story

First big thanks to the poster, very easy instructions to follow. After a couple of days finally got it to work and was able to upgrade my phone to 21y. I have three computers at home and all have Win7 loaded, lucky for me only one that work and enabled me to upgrade was the comp with Win 7 32bit operating system. If you want to upgrade make sure you are using comp with 32bit operating system also known as x86 and follow the instructions.

Thanks :)

[T-Mobile LG G2x] mt3g:
You can try to pull battery and sim card and just let it sit for a few minutes and then put it altogether again reboot that way. If the update tool didn't work maybe uninstall everything and reinstall, maybe update to a different baseband.
[T-Mobile LG G2x] ratza66:

This is a last resort that I can find in this forum on how to bring back your baseband. Whatever you do don't use Windows 7 64bit OS, for some reason it's not working with fiddling with LG firmware. Use Win 7 32bit or XP 32bit

If you did not get the OTA update how would you find it?
[T-Mobile LG G2x] nick7920:
window 7 pro and HellFirePhoenix_V2.1_32912

here is what I did with window 7 pro.

I had window firewall / Ms security essentials ON and did not get any port or window errors. just make sure you run as administrator wherever needed to be run.

I rename the .vbs without space to shorter name.

open cmd window run as administrator and run the .vbs.

once change was made to host file, I opened myself and checked if it was done.

I had HellFirePhoenix_V2.1_32912 and it would fail after 20% of Analysis. (error with message to restart phone). tried couple of time with same error.

I had my backup of old stock rom, I flashed that back.

update was done without any problem.

after that I install OneClickRecoveryFlasher and install rooted version of 21Y.

so far every thing seems to work fine.
[T-Mobile LG G2x] mario0choa:

You know you can take screenshots by just holding power and pressing the home key?
[T-Mobile LG G2x] apicia:
I never received the OTA upgrade. I have stock recovery on this phone. My other G2x got the update and I was impressed. Wondering how I should go about getting this G2x to 2.3.4. Hope the 14th was a true rumor.

Edit: Might just install CWM, like on my SGS2, but all the NVflash links are dead and the other tool the formats is corrupt. Can't find a way to flash CWM right now.
[T-Mobile LG G2x] mario0choa:
Why not doing through the normal route: Root (singleclick), install ROM Manager, flash recovery?
[T-Mobile LG G2x] apicia:
Used NVFlash to flash CWM on the phone. I heard that method does not work all the time.
[T-Mobile LG G2x] cricketAC:
Because thats a fake flash and with this phone if you flash with ROM manager and something goes wrong while flashing. You are literally out of luck.

CWM is the way to go.
[T-Mobile LG G2x] d12unk13astard:
Ya but look at my battery on g2x had no time 2 post even if I could have taken a screenshot.

Played with ICS for a while. It's pretty good and a few devs between here and rootz. I returned to stock ROM and recovery. I will try to get that OTA. Maybe LG Updater will work tomorrow like suggested.

I was having this issue for a while until I put my phone back to 21e Stock from ICS and it updated perfect after that.
[T-Mobile LG G2x] cervantesjc:
Would this method work to downgrade to an older baseband?
[T-Mobile LG G2x] WrenchGuy:
I couldn't get the OTA update to work...turns out my used "stock" phone had CWM installed (which I did not know, never used it) so the update process would stall.

I decided to familiarize myself with rooting, etc on this phone and after some work got it returned to completely stock, even stock recovery was intact.

At that point I decided to try the OTA again and it had vanished, no update available, so I waited for the the 14th and used the LG update software and got it done that way.

So far the update shows some minor speed and stability improvements, battery seems to be the biggest.

However, knowing now that LG and T-Mobile have really dropped the ball, and that Nvidia refuses to release a driver for devs, this will be the very LAST Nvidia phone/tablet product I ever buy, likely the same for LG unless they really show some better care for their customers. (there is no excuse besides incompetence why this phone does not have an official ICS update)

Still not sure what to think about T-Mobile...good prices and decent service but last to the dance in every technology.
[T-Mobile LG G2x] apicia:
This is where they dropped the ball. Why not update with ICS? Why not release drivers? Because... they want you to buy a new phone. Problem is that when we give this phone to the wife or kid and buy a new one, we won't buy an LG. Give us ICS. Give us driver releases. Then, we will buy another LG for there great support.
[T-Mobile LG G2x] edekalil:
Ok I think I am figuring this out. The instruction.docx will not open up when tring to update . Is there a way to download it sepratly? Once I get it I should be able to do the upgrade to the baseband for real.
[T-Mobile LG G2x] ecdy:
Success! Actually I used the info and files at

http://www.androidtotal.com/how-to-...al-android-2.3.4-v21y-update-t-mobile-lg-g2x/

which seem pretty similar to what is posted here. The instructions are not 100% correct but close enough to figure out. Tried using LG's foul updater on the web many times with no success but this method worked.

Incidentally, you have to make sure that USB debugging is on. No SIM card or SD card is needed in phone, though.
[T-Mobile LG G2x] edekalil:
I finaly figured it out and am now updated through the offline method.Thanks to all.
[T-Mobile LG G2x] meoshe:
I had trouble with this method with cm7 installed, I personally just used a stock rooted backup and it started working even with cwm nvflashed still. Also I used windows 7 64bit and verified the local host line to make sure the vbs script worked.
[T-Mobile LG G2x] projectzro:
F!@# IT!

i just gave up. I keep getting the crash screen just as it goes to upgrade the phone. it will unpack everything and set it up but when it tries to flash the phone it just crashes. i have tried EVERYTHING and followed all the instructions. why the **** cant LG just use NV Flash and be done with it. even when you use this to legitly upgrade your phone (never rooted or anything) it took me 5 hours just to upgrade my phone after i JUST BOUGHT THE DAMN THING!

besides i would still like to stick with custom roms, and AFAIK there arent any for the new baseband yet.

thank you for the guide though. i love phone but i want to kick the CEO of LG in the balls... just sayin
[T-Mobile LG G2x] mr_imaging:
Not sure if everybody knows this already, but as of May 14, LG's update tool is working again for upgrading to V21Y. So it is not necessary to download the different tools described in the OP. I installed the LG drivers and ran the mobile support tool from Windows 7 64-bit and did not have any problems. The update has addressed a lot of stability issues for me, it's worth a try.
[T-Mobile LG G2x] stevew84:
Oh wow really? Where do I download the LG Update Tool? Is that the B2C something or other program? Is the updater that LG Support tool, listed here?

So now I just plug it is USB and run the tool and be done with it?

you need to be on stock recovery i believe too!!!

running the updater on a 2000 compaq presario w/ XP. computer speed probably slowed this down a bit, but overall it took 30:37 for the update. it hung up at 4% for about 12 minutes, then all of a sudden started going and creeped its way along. off to flash owain's dominator, finally. :-)

Yea the only way this method works is making everything stock and ext3 file system.

[T-Mobile LG G2x] DsturbD:
ive read where others have gotten it to install without being stock, but that is through the lg update tool and using the kdz file. to do over the air you have to be stock (at least thats how it worked for me, rom and recovery)

That said, if I want to roll back as described, I use the OP process?

Perhaps this is obvious, but I want to be clear, as I am planning to fully restore go start to use some of the 2.3.4 ROMs, and getting away from CM for the time being.

Just a noob question. What benefits and risks are there to updating baseband? I have a really old mid-2011 baseband on my phone currently.
[T-Mobile LG G2x] cricketAC:
Better signal, battery life and instant GPS lock. It also helped some ppl get less or no reboots as it was the case with this phone before.

Risk, it's pain in the Beeep to upgrade your base band. Only the brave will try. ;)
