I'm wondering if it would be good for Core Memory to put a warning in the OP that this baseband won't work for voice calls in any other ROMs?
I flashed it and now I have to flash back to V21E because I still want to use my ICS.
(I know, it's my fault for not reading more first, but it would probably save a lot of time and hassle for other idiots like me.)

Good find on the open source site Kwes! This, combined with the Tmo Rep statement on their forum, bodes well that v21y is probably just waiting on Tmo testing/approval for update.

Like I said before someone go itchy fingers.This happends a lot with LG rom releases. LG releases it before the carrier signs off on it, The carrier gets angry tell them to pull it and then a couple of days later tells LG to go ahead and deploy it. I would not be surprised if people actually on TMO start getting OTA update available soon.

Hey kwes.. here's something that's weird. When I got the update, I got it directly from the too... then I used the 2.3.3 superoneclick to root. Then I installed the touch key lights apps whereas you can adjust your touchkey brightness..

Well, I was having some probs so I did a wipe and installed your 2.3.4 rooted from from the dev section. After installed, I installed touchkey lights, and it now says that touchkey lights is not compatible with the new gingerbread update.. and it doesn't work. ???? That makes no sense whatsoever...

My updater still shows V21e as the current version and won't update to V21y, but it's recognition of the V21y software is something I take as a good sign it will be back soon.

It is just reading that from your build.prop. That means nothing about LG releasing it. It will show whatever the build.prop shows.

Haha well I somehow got my recovery bugged so I can't do/test nothing until I can get one to install about to try v21e kdz and hope it installs one for me. It no longer recognizes my device as a apx device so I can't nvflash it says its a lg USB modem lol. Hopefully I can fix it. If not looks like I'm gonna get me a new phone.

So i finally got this kdz tool to work on my girls laptop, i created a partition to put xp sp3 on it. My baseband was unknown before the kdz flashed v21y and even after successfully flashing the new update my baseband remains to be corrupt/unknown??

I thought somewhere in this update it was supposed to flash a working baseband for my phone, should i try the v21e kdz or is there something i missed?

I had that happen too from messing around with my phone after I updated to v21y. I ran another v21y install and it worked even though it showed LG USB Modem.

When the KDZ updater is run, it decrypts the V21Y_00.kdz file into the LGMOBILEAX folder in the ProgramData folder at the root level of the C drive.
The result was the Star_Model.dll and V21Y.wdb files. The KDZ updater decrypts the V21Y.wdb file into .img, .bin and other files which are directly flashed to the phone. There arent any AP.bin or CP.bin files used.

I decrypted the V21Y.wdb file with LGExtract-0.2.1 which resulted in providing a folder named BIN which enclosed the 0,1,2,3,4_Split_Data.img files, android_fastboot_emmc_full.cfg,ext3_fastboot.img,fastboot.bin, P999_MDM.bin, recovery.img, Star.bct files.
It looks like a full NV flash recovery can be done with those files. Do you have those files, want those files, or will you do what I did to get them?

Did you reboot your phone? If you did and it still doesn't show the baseband, redo the flash.

Just wanted to thank everybody on this thread for all the helpful tips, finally got my baseband back.

    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

    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!
