Just make sure you have the proper drivers installed...I thin the driver file start with BCA something from LG.
I have done if for so many people......takes abt 15 minutes.

Just wanted to say thanks. My Wind Mobile 2x is now on the July 15 baseband. Had one hiccup where it said lost communication but i just removed the cable, plugged it back in and hit restart on the tool and it successfully completed.

Everything is going smooth so far, but when I click "upgrade start" in the read phone information dialog box I get the error

"Please install CSMG B2C client TOOL Select Tool -> B2C Client Setup menu."

Did a little searching but all I found was some russian thread about the o2x and some jerk spammed a thread with this problem and was threatened with a banning

Any ideas about this? Pretty sure I have all the drivers installed and actually I just found out I get this error even when my phone IS NOT plugged into the pc. What the Eff?

Ok got it to work. Here was my process:

Uninstall everything related to mobile phones (except the android SDK)
-Uninstalled LG United Mobile Driver
-Uninstalled msxml.msi
-Uninstalled motorola and other phone drivers (flashing roms for friends)

Reinstalled all relevant drivers and downloaded B2Cappsetup.exe from (http://www.mediafire.com/?nyt1jdkmycd). The latter I dropped into the kdz dir and opened but then closed. (not sure if important)

I then followed the instructions in OP and BAM, it worked!

Note: I also did this on a win7 machine. With WeaponG2X flashed and CWM 5.0.2.0 flashed. It still worked flawlessly (Jul 15 2011 baseband woo!) but it did flash stock recovery (wish LG would keep its dirty hands off my recovery!!)

Here is a paste of my update log, probably not useful, but I like to be thorough!

Edit: I like the time travel at the end there, timestamp goes from 18:14 back to 18:11. What the hell LG!?

I just flashed everything back to original and managed to use the LG updater tool. The process sucked, but it worked.

Is it possible that I make a back up of my current rom and then restore it after the update?Am I going to loose CWM after using that method and if I do, how do I get it back?
Thanks

If you have CWM installed, just do a backup.
Then install the baseband..

re-install CWM after the baseband update.

restore via CWM and you will have everything Wind, except the baseband.

Thanks for the fast reply! So I`m currently running CM7 with CWM 5x; and planning to flash the baseband on win7 pc. From what I understand, I don`t have to go back to stock to perform the update, and win7 should not be a problem for the process. How do I flash CWM back? With Nvflash? Also will my phone remain rooted? I`ll appreciate your help. Thanks

Just fopllow the thread above.
You reflash CWM with NV falsh.

When you falsh your baseband, make sure you have the LG drivers loaded, the KDZ file and the V21e file....follow the instructions.....takes 20 minutes at most and you are all done.

If you flash a rooted rom via CWM, it will be rooted.
