CDMA 2.7, I am going to try the demo and see if that helps.
Read also returns the same error. It connects fine though.


EDIT:
Figured it out!
Don't connect to the modem port.
I should have read the directions more slowly.

Okay... I've uninstalled any LG drivers I previously had installed, installed the drivers you uploaded.



Turned on USB Debugging on my phone and plugged it in. Device Manager shows this:



I right click, "Update Driver Software" => "Browse my computer for driver software" => "Let me pick from a list of device drivers on my computer"... This brings me here:



Unchecking "Show compatible hardware" gives me a lot more options, including a couple of references to the "HTC Dream" (which I believe is another name for the T-Mobile G1, the first widely available Android phone)... But nothing about USB Serial.



The only thing I have showing up under ports is a "Printer Port (LPT1)." What am I doing wrong? Any clue?

Same exact results here as above, can't get the USB Serial drivers to show up anywhere after uninstalling and installing the new drivers that were uploaded...
I've tried it on Windows 7 Home 32bit and also Windows 7 Ultimate 64bit with the same results (of course i'd already tried the install with the other drivers on both machines... Should I dig out an XP machine to try this on?
Has anyone with an un-rooted Optimus V gotten this to work?

I hope after all this trouble (assuming i get it to work) it actually does help with all the 3g data outages like i've been promised

You didn't uninstall the Android Sooner Single ADB Interface Driver. Right click on it and select Uninstall. When it asks you to confirm, check the box to delete the drivers. Then follow the directions I posted to manually add the correct driver.

I guess he did reference me.
Hmmmm, really? OK... Yes, it was spread out (in one thread, not multiple). But you gave no mention where you obtained the info from. But thanks for cleaning it up, cause it did help a few people get going.

God, I hate Windows. There's no Mac-native or Linux-native programs that can do this, are there?

At this point there was nothing to right click on, which I assume means that when I uninstalled the drivers through the "Uninstall Programs" control panel it left some files behind that were mucking up the process. So I went ahead and reinstalled the driver's from LG's, website, reconnected my phone to get the "Sooner Single" to show up, then right clicked on it, chose uninstall and make sure Delete was selected.

Then I went in the Uninstall control panel to make sure everything was deleted. Then I deleted anything that looked like it was owned by LG under C:\Program Files, C:\ProgramData and C:\Windows\System32\Drivers.

Then I installed your drivers, as linked in the first post and plugged my phone back in. And it showed back up as the "Sooner Single" interface, but had a "Device Cannot Start" error on it... Which I'm guessing means that driver was actually in your package. Right clicked, uninstall, make sure I check Delete... Unplug and replug my phone back in. This time I get an "Android USB Device" that the system was unable to find a driver for.

So I followed your directions.... Update Driver, Search my computer, etc. There appears to be both an "LG Electronics, Inc" entry and an "LG Electronics Inc" (without the comma) entry. One of them has two Serial Port drivers, and two NMEA GPS Port drivers, the other has three of each. I've at this point tried all five of the Serial Port drivers.

The ones from the group of three (I can't remember if that's the one with the comma or without) required me to reboot my computer when I installed them and then, after the reboot, had a "Device cannot start" on them. The other two managed to start, but when I hit the "Connect" button in the CDMA Workshop it says "Failed to open COMx"... I tried switching around between COM1, COM3, COM5 (making sure to always have the same port selected in both the device manager and the CDMA Workshop)... I tried messing with the baud rate setting, again matching them in both locations.

No go.

I'm doing all of this on two machines, btw... An installation of Windows 7 64 bit running under Parallels Desktop on my Mac, and an install of Windows 7 32 bit running on a friend's computer with no virtualization. Getting identical results on both. Well, I did discover that my friend's computer freezes up mid-POST if my phone is plugged into its USB port while it's rebooting, which was just a little bit of extra frustration to deal with.

Any more hints?

I'd really like to get this working... I've had data outages of several hours almost every day for 2-3 weeks now, usually during prime time usage hours (i.e. around noon, and around 4pm to 7-8pm.) Would love anything that would make the stop or even lessen it.

Wow Kate, ok. Install one of the drivers that is labeled "LGE Android Platform USB Serial Port", I don't think it matters which one. Then make sure no other com ports conflict with the com port you choose. To make sure, restart your computer after changing the port and verify it didn't change. You obviously have debugging enabled on your phone, otherwise the driver wouldn't even appear....Hmmm. I agree that windows makes all of this so much harder than it has to be. The problem with the drivers is a perfect example of how something so simple requires a full days worth of trial and error to fix.

Actually, the only part I got from your thread was the procedure to use the Demo version of CDMA workshop to get the MSL code. The rest a pieced together from XDA posts and forums:
http://forum.xda-developers.com/showthread.php?t=940612
http://mark.cdmaforums.com/QPSTSetup.htm
http://www.evanvaughan.com/default.a...EED25AA49D4B1C

I also didn't use pirated software to get the VM PRL. When you read from the phone using QPST, even though it gives an error, it does download the phone's PRL. You can then save that to a QCN file with the rest of the phone settings. You can then extract the PRL using QPST's Roaming List editor. You should know that the pirated copy of CDMA workshop that is floating around online has been flagged as containing a virus multiple times.

Again, you copied and pasted my entire post and gave no reference to me. I did not complain because this isn't anything besides a walk through.

I'm going to be posting a new PRL soon just for VM users that has all of the roaming features of 60676 removed and adds in the difference from 61007. Feel free to post it in your thread too.

I didn't? Maybe you should go read your post #3 again. You admit to me referencing you. I did mention it and went as far to call it "nice". That is more then you did for me.

Haha, I'm really not looking for a pissing match, and we both have links to each others threads. So I'm just going to leave it at that.

I posted the new PRL if you want to try it out.
