No. Mine is stock and staying that way. Probably go to sell it soon. It is early afternoon where I am. I am not up late.

I might do it tomorrow.

I just used GetRIL on my phone. It says the baseband doesn't match although it shows correctly in About Phone. I wonder when they're going to update their RIL database.

I knew you are selling your G2X but where can you sell it to a trustworthy person? If you do over the internet, you're taking a risk.

Updated last week to V21y through lg software. Was great for about 4 days. It started locking up, rebooting and causing issues. I did not have rooted so i flashed the rooted rom. It also lasted about 4 days. Now my phone is continuously locking up and has rebooted several times. Have not been out of the house for several days. Have been using wifi calling. Went to the store last night and had no signal whatsoever. I rebooted phone and got 1 bar for about a minute. My wife that was sitting right next tome had 4 bars of g. This update did not change much. It did the same as reloading the rom when you call t mobile for support. Going to try ice cream sandwich. Wish me luck.

You'll have to revert your baseband if you want your calls to work. CM and devs don't have ICS working with the newest baseband yet in terms of calling.

I haven't had problems with V21Y but I'm waiting for the flood of complaints by customers who get the OTA update. If there are many, I wonder what T-Mobile will do (nothing????).

The problem is beyond ril files. They changed ril files in source too which in turn changes lots of jar and framework files. Simply swapping them out does not work. Already tried it through source and through the final rom.

For an OTA you need stock recovery. Use the one click recovery flasher to flash recovery back to stock.

Pardon my ignorance - when I rooted I did not use super-one-click as it did not work with the G2X once it was upgraded. Can I still use the one click recovery flasher to flash back to stock?

I've been on the T-Mobile G2X forum and seen a few people that have gotten the OTA and their phone not working. Doing a hard reset (not just a factory reset) has seemed to correct the problem.

They're not talking about super-oneclick, it's the one-click nvflasher.

So is it really worth un rooting and updating? I'm sure the update has Google video chat correct? I read a lot of pages and it seems it might be worth it, I hate freezes, but I still haven't decided lol :-\

If you want to use GB and/or ICS modded ROMs (other than a modded GB 2.3.4 V21Y update), no.

failed update

I tried to update from 2.3.3 to 2.3.4 but it failed. the updater actually got pass the 4% after I put my phone into s/w mode. I think it got up to 36% before it had a communication error. I pasted the results below. So my phone is still on 2.3.3 but now I can't call. More accurately I can call but all I hear is static. What can I do to make my phone functional again.

As I learned from other posts, the update starts with the baseband. So there's a chance that you have already on the new baseband, regardless the failed update. That's why the static noise instead normal voice.
Would you please, check your about phone info?
If so, simply flash kwes1020's rooted 2.3.4 ROM from the dev section.

Just run the KDZ method and update to 2.3.4. You already have the new baseband so you need the get 2.3.4 on your phone. As has been stated before, when you get a comm error all you need to do is unplug the usb cable, plug it back in and press restart. It would have continued and finished the update. Do the KDZ method and when you get a comm error just pull the usb cable, wait, plug it back in, wait and press restart.

As an alternative, since you already have the new baseband, install CWM recovery and then flash a zip file of the new rom and you will be good to go.

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.

I tried every which way to update my phone only to have it tell me I'm up to date. So, I'm assuming I have the lg p999wp or something. Apparently, only 3 out of 4 models have the update. So, unless there's something I'm missing, which I doubt since I searched the forums with as "v21y update" and none of the posts work, I guess I'm beat until they decide to release it for my model.

The offline update, the one with the http server running which intercepts communication with LG, should work because the updater only looks for "P999".

Here's a few lines of code disassembled from the Star_Model.dll which show that.
push SSZ1003E068__P999_MDM_bin


push SSZ1003E8B4_P999


db 'P999_MDM',0


db 'P999',0

The updater checks the baseband also. If the baseband already been updated the updater will refuse to update the rom.

    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

    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!
