Ok.. I am very confused right now... when I connect the phone to the LG installer..it detects my phone and it says that my version is V21Y but my phone says V21e in "about phone"... is this normal?

Did you ever update the baseband to v21y baseband and then downgrade to v21e rom? It is possible the updater is looking at the baseband to determine the version of the rom.

Updater froze

Do the .kdz update on a computer running Windows XP. The offline update works with Windows 7 or Windows XP. Instructions must be followed exactly. Drivers must be installed and every .exe program used in updating must be set up to run as administrator.

I followed the instructions through. The updater freezes everytime at what seems to be the end of the "Download" process. This is what windows says the problem is:
Problem Event Name: APPCRASH
Application Name: LGUserCSTool.exe
Application Version: 1.5.4.8
Application Timestamp: 4f0d2d7f
Fault Module Name: Star_Model.dll
Fault Module Version: 1.0.0.8
Fault Module Timestamp: 4e5db4f9
Exception Code: c0000005
Exception Offset: 00039ba5
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 1033
Additional Information 1: 0a9e
Additional Information 2: 0a9e372d3b4ad19135b953a78882e789
Additional Information 3: 0a9e
Additional Information 4: 0a9e372d3b4ad19135b953a78882e789

Not that I know what any of this means. Crazy. Any ideas?

It may be a corrupted .kdz file. Download it again and retry.

    Original Post

    I started up the LGMobile Support Tool and selected supported model. When I scrolled down, it shows new firmware, V21y, for the LGP999DW, LGP999DWDU, LGP999DWP but still shows V21e for the LGP999WA.

    Update 4/20/2012

    The V21Y_00 update (LG T-Mobile branded Android 2.3.4) is not available anymore through the LGMobile Support Tool and LG has removed the direct download link to the V21Y_00.kdz file. Instead, thanks to another member, overground, it is now available from http://www.mediafire.com/?obr7717n1ebj2qa
    Get it while you can in case LG files a DMCA complaint against Mediafire.

    Yeah, seems LG has removed the update from their servers.
    I've uploaded V21y here = http://www.mediafire.com/?obr7717n1ebj2qa
    @CoreMemory: Feel free to put the link in the OP.


    IMPORTANT!

    A lot of peeps have had trouble installing the V21Y_00.kdz file. There are many variables which can cause installation failure which are due to "operator error" and/or computer idiosyncracies. This thread and others have information about various methods used to overcome update problems so, if at first you don't succeed, read the thread(s) and keep trying.

    As well, this update will install a new baseband and an LG and T-Mobile branded Android 2.3.4 ROM. LG has made some serious changes to the baseband which prevents other ROMs, except for a modded version of the same Android 2.3.4 ROM or the newest versions of CM7 and some other ROMs (which you can find by searching for compatibility with V21Y/March baseband), from working with in-call audio which is the audio for using the phone as a phone - to make and receive phone calls and for the people on each side of the connection to hear each other. So, if you want to install modded ROMs, other than the a modded version of the V21Y Android 2.3.4 ROM installed by this update or one such as CM7 which is compatible (Weapon isn't), don't update. If you do install it you can revert back to V21e by downloading it and using whatever method you used to successfully install the V21y update.

    Before you update to V21Y, save a CWM backup of your existing ROM which you can use to revert back to the installation you now have after you reinstall V21E (including the V21E baseband). You can't use CWM to reinstall V21E, you must use the KDZ updater with the V21E kdz file then use CWM to restore your previously installed V21E modded ROM and Kernel. Good Luck!

    If you want to revert to V21E Android 2.3.3 and the compatible baseband, get the V21E kdz update file here: http://www.2shared.com/file/WVH0y09f/V21E_00.html

    INSTRUCTIONS

    There's usually no need to revert your phone back to a stock ROM. If you use the following method, you can install any G2X/P999 .kdz update file (V10f, V21e, V21y, etc.) over almost any ROM, including modded ones. If you want to eliminate a potential update problem, revert to a stock ROM first. If the update didn't work, and you bricked your phone, you need to revert back to a stock ROM which you can do by following the instructions here: http://xdaforums.com/showthread.php?t=1248644&highlight=unbrick+phone

    I successfully used Windows Virtual PC in XP Mode to install the .kdz file but you may be able to install it in Windows XP and Windows 7 (32 and 64 bit), as others have successfully done, by using LG_KDZ_FW-Update_OfflineFix as follows:

    First,
    From the OP by adixtra at http://xdaforums.com/showthread.php?t=1287236
    1. download: LG_KDZ_FW-Update_OfflineFix (OFFLINE INSTALLER DOWNLOAD)
    2. download: KDZ_FW_UPD_EN (DOWNLOAD FLASHING PROGRAMS)
    3. download: ROOT USING SuperOneClick
    DO NOT DOWNLOAD ANY OF THE OTHER FILES THERE!

    Alternative to downloading the #1 and #2 files listed above,
    here's a link to instructions and files, by spyrosk, which includes almost everything (except for SuperOneClick and the .kdz update file) which installs and runs by using an included VB Script
    : http://xdaforums.com/showpost.php?p=22189294&postcount=30

    You will still need the .kdz file of your choice to use with it.

    Second,
    Download the V21Y_00.kdz upgrade/update file which, although LG has removed the V21Y_00.kdz file from their server, thanks to another member, overground, it is now available from http://www.mediafire.com/?obr7717n1ebj2qa

    Third,
    From the OP by Kairi_zeroblade at http://xdaforums.com/showthread.php?t=1566681
    download CWM-Based Recovery 5.0.2.8


    Fourth,
    Carry out the steps in adixtra's OP at http://xdaforums.com/showthread.php?t=1287236 with the V21y_00.kdz file you downloaded by selecting it from wherever you downloaded it to.

    It takes about 10 minutes to complete.

    Fifth,
    Afterwards, you will have to root it with SuperOneClick and install CWM if you want to use it for backing up, restoring, etc. (saving your butt) otherwise if you restore it will be the stock v21y installation.

    XP MODE Instructions

    If you don't succeed with Windows 7 or Windows XP (which it should have), it may work with XP Mode in Virtual PC. The LG Modem drivers have to be installed in Windows 7 first then, after you get XP Mode operating, carry out the steps again. After you connect the phone to the computer, you will have to attach the phone's USB port in XP Mode from the XP Mode USB menu. During the update process, the phone's USB port will detach, you'll hear an alert sound, and you must reattach the USB port again from the XP Mode USB menu. That will happen a few times until the process completes. Here's instructions from Microsoft about how to install and use Windows XP mode in Windows 7 http://windows.microsoft.com/en-US/windows7/install-and-use-windows-xp-mode-in-windows-7.

    Also,

    Have a look at Enyah's thread for information about how others have successfully updated to V21Y_00.kdz http://xdaforums.com/showthread.php?t=1610597

    Have a look at Rafase282's post too, it repeats some content from my thread and others' but has some additional content http://xdaforums.com/showpost.php?p=26935107&postcount=3

    I am hesitant about whether devs will support the new baseband. Anyone hear if there is active develoopment to make ROMs that support this?

    I'm working on one. Still a ways to go but shouldn't be too much longer to get it stable.

    Did you read the posts above yours? It appears LG pulled the update. Download the KDZ from the OP that CoreMemory so generously provided and use the KDZ Updater on a Windows XP machine to perform the udpate.

    Thanks jboxer for the credits.

    so why does this BB not work with ICS roms, but the older BB does?

    if i go back to stock to get this BB and then flash an ICS rom and it doesnt work, is there a way to put the old BB back on the phone so i can use ICS?

    i dont like this update. bought the phone yesterday with it already on, didnt know about the call sound being f''ed up. until i got a call today. now i have to go back to the stock rooted rom in this forum... :( i miss miui

    This has already been CLEARLY covered many many times but I'll entertain you guys...

    The new Baseband is perfectly fine. Really. There's NOTHING wrong with it.

    What's WRONG is that it is NEW. Get it? NEW? .. That means developers haven't had time to implement compatibility for it into existing Roms.

    Which means if you install CM7 or CM9 or even Tsugi or Weapon or ANY ROM THAT HAS NOT BEEN UPDATED TO USE THE NEW BASEBAND, then you are going to have problems. Simple. Clear. Covered lots of times.

    Now, as far as a solution... there are instructions all over the forums which I won't link to since you can use search, to revert back to the July Baseband. Yes, that will even work on a brand new phone that come preloaded with the new Baseband.

    Good luck!
