I tried to downgrade LG P500 from 2.2.1 to 2.2 by following these steps.
Install msxml.msi from the uncompressed directory
Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT
Select PhoneMode : DIAG
In KDZ file : Choose the ROM file you downloaded (V10G_00.kdz file)
Press Launch software update and wait (It will be 10 minutes or so). In your phone it will appear "Emergency mode". Wait until it reboots.
The phone never rebooted. When I manually try to reboot, it comes to Android screen and never gets past it. Has anyone faced this issue?
Thanks.
FIRST TRY TO PRESS THE POWER BUTTON FR FEW SECONDS WHEN ITS SHOWING THE ANDROID SCREEN IF IT LOAD STHEN ITS FINE ORELSE TRY THIS
IT does happen so in order to get it working make sure that u have enable usb debugginng and disable lg modem driver .
Restart ur pc
hold volume up and home button and connect to ur pc via usb
flash using kdz flasher choosing your rom file in diag/emergency/cs emergency(any 1)option
after it succeed flashing it will show battery getting charged but it never turns on on its own so manualy turn on the mobile.
Note : Do not disconnect usb from pc till the android loads up in ur mobile
if all doent work just gv it back to service they will get it repaired
Solution!
As many have stated, pushing the v21E_00.kdz via the KDZ_FW_UPD program does work. It's just touchy.
This is a step by step guide to get you back in to working shape.
Note: You MUST do this via a PC running Windows XP. Running Vista/7 in compatibility mode is not going to work, period.
Edit: As an alternative, a virtual environment running XP will do the job. Those steps are up to you.
Part 1: Download the files you will need below.
V21E_00.kdz
KDZ_FW_UPD_EN
One-Click-G2x-recovery-flasher-06-16.rar
LG USB Drivers G2x
Part 2:
1) Install the LG G2x USB drivers to your WinXP machine.
2) Extract the entire contents of the One-Click recovery in to a folder and keep it handy.
3) Remove the battery from the phone. Hold both volume buttons and plug in the USB cable. If you are asked for a driver, look in the APX folder where you extracted the One-Click recovery archive.
4) Run OneClickRecoveryFlasher.exe and flash the stock recovery. Wait for the process to finish and close all windows and unplug the phone.
Edit: It's been reported that some users have been able to boot in to their old rom after this point. If you can, you're done. Go
back and put CWR on and flash whatever you want. If you are still stuck, continue this guide.
5) Put the battery back into the phone and turn it on. You will be back at the S/W Upgrade screen. This is where you want to be! Now plug the USB cable back in to the phone. If everything is up to snuff you should have no driver problems at this point.
6) Extract KDZ_FW_UPD_EN.7z in to a folder. Inside is a msxml.msi. You need to run and install this first!
7) Run KDZ_FW_UPD.exe.. Leave the type set to CDMA and the phone mode set to DIAG. DO NOT CLICK ON "Read phone information"
8) Click the folder icon and load the V21E_00.kdz
9) Click launch software update (and pray!)
What you will see:
The log window will immediatly show:
22:41:02 : Launching SW update
22:41:02 : Unpacking KDZ
Then it will stop for a while.
After this you will most likely see:
22:41:16 : KDZ file extraced
22:41:21 : Files were extracted.
22:41:21 : LGMobileDL Load.
22:41:21 : Port = 5
22:41:21 : Connecting to phone
22:41:33 : Check Phone mode = 1
It will pause again before you see:
22:42:08 : Phone type check.......
22:42:08 : LGMobileDL.DLL Loading....
22:42:08 : _SetAuthMark Fail
22:42:08 : AuthMark°¡ Á¤È®È÷ Phone¿¡ Write µÇÁö ¾Ê¾Ò½À´Ï´Ù!
22:42:08 : _SetAuthMark Fail
22:42:08 : LoadCDMAPhoneData() Error
22:42:08 : _DetachDLL Call
22:42:08 : _DetachDLL Call End
22:42:08 : Param : Path = C:\Documents and Settings\All Users\Application Data\LGMOBILEAX\Phone\V21E.wdb
22:42:08 : Param : moduleDir =
22:42:08 : Param : waitTime = 33000
22:42:08 : Param : UsbHighSpeed = 0
22:42:08 : Param : PhoneMode = 1
22:42:08 : Param : BinVersion = V21E_00
22:42:08 : Param : AuthMark = 0
22:42:08 : Call fn_StartUpgrade
Finally after another pause you should start to get spammed by the following message:
22:42:41 : CDMA: wParam = 2007, lParam = 0
22:42:41 : Model Dll Msg Not Found(2007, 0)
You will even hear the USB disconnect/reconnect sound several times.
The sound and spam will continue until the lParam counts to 100.
It should look like:
22:46:25 : CDMA: wParam = 2005, lParam = 100
22:46:25 : Model Dll Msg Not Found(2005, 100)
22:46:25 : CDMA: wParam = 2001, lParam = 0
22:46:25 : Model Dll Msg Not Found(2001, 0)
After it gets to 100, your phone will reboot to the LG logo before going
blank. After a few moments of the blank screen you will get the TMO G2x splash before being dropped back in to your working phone.
Be patient as this takes a while. If at any point the program freezes for more than a few moments, it's most likely going to fail and you will need to try again.
Hope this helps. =)
Thanks to everyone who helped figure this out.

Will either 32bit or 64bit XP work?
U can use win 7 just get a program called XP mode its a virtual win XP
Sent from a guy living in a van down by the river
XP mode didnt work for me...device disconnects during upgrade and xo mode maes you reattach usb devices...which hangs the upgrade softwa
Ahh the links for V21E_00.kdz are all dead..on ALL of the forums
Step 3 not wprking for me. Wont even turn on while holding volume butons then install usb. Where do we get the drivers and what ones do we need? Do we install them on the phone or cumputer? How do we do this? When on click on the link for step 3 to dpwnload it brings up page saying not found. When I go to the xda page for step for to download it brings up a bar code type deal. This makes no sence. Step 5 through 10 I have pretty much done but everytime I press update software it either freezes the window or blanks the window. Or says it cant read my phone. Nor does my computer read my phone anymore. And when it does it mentions something about how the device in the usb port has manfunctioned.
Sorry for all the weird and noob questions. But the truth is the only reason I even attempted this update was b/c it was 4 easy steps which I followed to a T according to LG's website. I even read through then twice just to make sure. I am not a cumputer guy so if someone can help me out with this in simple terms that would be great. I am highly irrated at this situation that the manufacture would release a update and it fail for so many people. Now I have a awesome phone stuck on S/W screen

If your phone is stock and not rooted (or you haven't flashed an alternate recovery) step 3 can be skipped. Drivers are to be installed to the PC and make sure you scroll down to the T-mobile portion in the linked page. Just download this: http://s3.amazonaws.com/lgforum.com...nal/LG _USB _Drivers_All_4.9.7.zip?1298055768 and this: http://s3.amazonaws.com/lgforum.com...Mobile_Android_USB_Driver_v2.2.zip?1303408893
Unzip both and install to PC.
Just a note: It took me at least 3 attempts to get this going. Kept freezing at something (not exact) like: Model Dll Msg Not Found(3501, 1)
I'll try to get a mirror up for the .kdz file soon.
I know it says it won't work on Win7, but the upgrade doesn't fail... The program just stops responding and pretty much force closes. Is that what you meant by won't work on Win7?
I'm running XP and I still can't fix it. Doesn't launch the .kdz file unless the phone is disconnected (freezes when it's connected). When i try to plug it in after it says it has been launched, it does not recognize my phone.
SUCCESS!!!!
Although it's very frustrating when something goes wrong, I actually welcomed the new experience. After all, you do learn from your mistakes
Uploaded V21E_00.kdz and fixed the link in the OP.
This doesn't work. How many times do I have to post this in various forums before anyone hears me. I can't be the only person running XP and following the simple step by step instructions that can't get this to work.
I try a different way thinking that if I just run cwm recovery and install the old .rar file it will be fine. Didn't work, asked in the development section about this, and I get sent back to a post about this method that I have tried 100 times. I have uninstalled everything reinstalled everything. IT DOESN"T WORK!

You can use XP mode to do this, and yes the USB driver will detach. Just re-attach it and the flasher will kick right back in where it left off. I had to do this just twice during the procedure. As long as you stay on top of it you will have no problem.

IT DOES WORK! You should not be installing any .rar file via CWM. I think your problem is what you're doing with that .rar file. It needs to be extracted and run from your PC. CWM recovery has nothing to do with this...but you'll need to put it back when you're done. From the OP:
2) Extract the entire contents of the One-Click recovery in to a folder and keep it handy.
3) Remove the battery from the phone. Hold both volume buttons and plug in the USB cable. If you are asked for a driver, look in the APX folder where you extracted the One-Click recovery archive.
4) Run OneClickRecoveryFlasher.exe and flash the stock recovery. Wait for the process to finish and close all windows and unplug the phone.
OneClickRecoveryFlasher.exe is in the NVflash folder.
is there a way to put the phone in s/w upgrade modE? im not bricked just want to be able to upgrade this for the baseband
Can I get step by step instructions for someone stuck with sw screen that has a completely stock phone. I have tried the above steps about 50 Times with same results. I don't know what I am doing wrong.
Phone Not Found
I have tried these steps a number of times so far and everytime I run KDZ it goes through the motions and says that the Phone is Not Found.
Anyone else get this?

I only tried the .rar file after trying the steps in this message 50 times. I figured I needed try something new. I am on a third machine.
I have already flashed back to stock recovery. So, I guess I just need to install all those files to this machine and try everything again.
Hello! I tried to update my LG Optimus Me P350 with KDZ Update tool, but the update was unsuccesfull and now the phone is stuck in emergency mode. I can't use any combination of buttons, even when i connect to my pc, this thing remain stuck in emergency mode. What can I do?
Same for me :-(
I found a solution and it's working:
1.Download KDZ updater and uncompress it
http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html
2.Install msxml.msi from the uncompressed directory
3.Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)
4.Turn phone off somehow (remove battery etc.)
5.Install drivers properly•Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
•Install the LG drivers by selecting the update manager from the lg site
•Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
6.Press and keep pressed "Volume up"+"Return" and connect USB cable to phone
7.Yellow screen with text emergency mode should appeared
8.Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
9.Run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT (I have one report that CDMA mod works too)
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
10.I Recommend do not switch phone off. There was some people, which done it and after they were not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....
11.In KDZ file : Choose the ROM file you downloaded in the first step
12.Press Launch software update
13.Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
14.Make sure that all update was done successfully. Phone should restart itself automatically
15.Disconnect the USB cable from the phone
16.Press the three button combo for HW reset of device i.e volume up + home + power button
