the error is: "upgrade error WParam : 100 LParam : 502"
By the way, the reason i need to flash the original ROM is to try and get dir of the start-up Emergency Mode error. Meaning, if i shut down the phone, and turn it on it gets intro Emergency Mode. I have to pull the battery out for like 15 - 20 minutes to boot again normal. You can imagine this is annoyng. Once booting, the phone runs perfect...

Maybe you have some opinion on this one?
Thanks!
Did you ever figure it out? I am having the exact same issue (phone goes to Emergency Mode) and the exact same error when trying to flash with Kdz.

I had the same
Code:
upgrade error WParam : 100 LParam : 502
on a Windows 7x64 fresh install I think its caused by a bad ROM flash which happens to clash with drivers.
KDZ->Read Phone Info always gave device not known errors then crashed.
I chose to use another PC to make sure driver issues were gone (PPL say that win7 works but I changed to a Vista laptop for a better result) Here is what i did:
**Use a Windows XP 32-bit PC for best results**
1. Use the LG Support tool Run as administrator to DL latest drivers
-
2. Reinstall 3 drivers in order from C:\LGP500\USB_Driver and C:\LGP500\USB_Driver\LG_SmartPhone.
-a. LGUnitedMobileDriver_S4981MAN32AP22_ML_WHQL_Ver_3.2.1.exe (version will vary)
-b. LGWindowsMobile_USBDriver_WHQL_ML_Ver_1.0.exe
-c. LGSmartPhone_ModemlinkDUNDrive_WHQL_ML_Ver_1.0.exe
Restart if required
-
3. Download crecked's Original LG Firmware.exe and get your .KDZ
-
4. Download Software update KDZ and install msxml.msi as administrator
-
5. Remove Sim, MicroSD, and battery.
-
6. Connect the phone and boot it in emergency mode (still no battery)
-
7. Goto device manager and disable Modems->AndroidModem
*MUST RESTART PC HERE!*
-
8. Check ALL modems are disabled in task manager and then set KDZ_FW_UPD.exe to always run in compatibility mode for Windows XP SP2
-
9. Ensure Phone is in yellow emergency mode and no battery... (USB connect noise as soon as plugged in)
-a. Run KDZ_FW_UPD.exe as administrator (MUST be XP SP2 compatible) and set type: 3GQCT and PhoneMode: EMERGENCY.
-b. Select your previously downloaded KDZ file from using the program in step 3, and Launch!
-
10. If finished then wait 2-3mins and turn on phone (if not already booting), Insert battery, and close KDZ. Initial startup may take 10 mins
**Again, Win7x64 did not work for me (even in XPSP2 compatibility mode which is a MUST) so I used Vista 32-bit but XP 32-bit is preferable**
Thanks guys, this forum was amazingly helpful and a huge learning experience for me, mods can feel free to delete this post, or even move it to where it should be I just wanted user DarkAgent, and RUwin to know, and to have the result searchable so others can receive the same amazing tips I had!

I hear a humor that when the phone is in emergency mode and it's conected to pc and the pc is not recognizes it you have to shake you phone to get it working... see if it is true...
