Hi All,
I tried to discuss my problem in a different topic, but i think in this topic i'll get solution to my problem.
Here is the case:
"Hi All,
I have some problem with the smartflash thing.
I installed the driver on my win7. I started the smartflash app, picked the battery, power, and volume down at the same time, put the cable on, and the smartflash cannot recognize the COM port...
The thing is, i did this procedure 2 mounth ago, and it worked. Yesterday i want to update my phone, but it didnt worked, except the factory reset
I did the LG PC Sync too, and it says, my phone is up to date... (my baseband is 0405)
Thank You in advance, and sry for my bad english

Afterwards do the procedure with the phone
Take bat out plug in cable put bat in press the button Don't open smartflash and it should still be closed..
Check if the phone is in se mode and check the device manager again u should have a device named lg usb serial port on a high com port it should be under usb devices. If you get and error on the driver or conflict goto the 1st post on this thered and download smartflash driver and update only the new lg usb device with him while the phone is still connected cz otherwise the device will desapear
That's about it if all is o.k open smartflash select on the right the driver and on the left the com port and you're done.
Good luck

Hi, i'm trying to root my stock LG Optimus 2X v20d Gingerbread with this: http://forum.xda-developers.com/showthread.php?t=1327599
I'm unable to connect to the computer in APX-mode. I tried connecting to the CPU at the front and the back (port on the motherboard) and whenever i tried to connect my Optimus 2X, nothing happens when i pressed both vol up+down when connecting to computer. I've been disconnecting and connecting the USB device over and over again but to no avail. Tried switching out the USB cables also did not work. No prompt to install the drivers appeared. I'm also unable to find any APX-related devices in Device Manager.
I have tried to list hidden devices in Device Manager to check if there's any APX-related drivers too, but still, to no avail.
I'm really out of ideas here. Can anyone help?
[EDIT] To add-on, i previously used MIUI before reverting back to stock froyo and then upgraded to stock gingerbread via LG's update tool. The reason is, my computer won't detect my MIUI in USB storage mode, but i remember that my MIUI'd Optimus 2X did connect to the computer as APX-mode before.
Did you remove the battery first? Won't work unless you do.

Yes i did. I took out everything (battery, sdcard, simcard).
but i remember that my MIUI'd Optimus 2X did connect to the computer as APX-mode before.

This should mean that the APX-driver already is installed, so in theory you should be able to skip step 2.
If however there's no "NVIDIA USB Boot-recovery driver for Mobile devices"-device visible then indeed APX-mode is not recognized.
Just to make sure you can try to do it on another computer and see if that registers an unknown device. If it does not, then well, something is broken.
Problem solved, rooted!
Woah, i nearly gave up until i decided to gave one last try to root this phone today. It worked!
Turns out that the connecting at the front works too (well, at least for me). This time, i only took out the battery (left the simcard/sdcard) in the phone and connected the USB cable to the O2X, and a pop up on APX appeared!

Hello people
I'm new here, in terms of asking questions and seeking help
I have the LG Optimus P970
A few days ago I made the update to ICS, and by proceeding with this page, hackmyandroid.com/optimus-black-p970-official-ics-update/3299
After that, not impossible to connect the phone to a PC, even the software update mode, it can not recognize, anyway to connect it just throws a slow charging.
Is there someone who knows what it is.
I'd love to go back to the old software, but there is no way to detect it pc
Sorry for my bad english
Thanks in advance
I forgot to say, before the update, and my computer still recognize the phone, connecting it over sony usb cable, now it is no longer recognized by the Sony USB cable, and I do not have original LG USB cable.
Perhaps this is the reason why a computer will not recognize the phone

Your problem can be the non original cable or........reinstall the drivers and try again

I have the original cable, but still the same problem.
I have all drivers installed, I can transfer files between the phone and the pc, I can use the LG suite,
But I can't see my phone on the ADB console, I can't use smartflashtool cause the phone isn't recoginized.
yesterday I tried with lg cable, and wall charger, in both cases, said slow charging the battery, I tried on three different computers, I tried to reinstall the drivers, like the software blocked communication with the phone, just charge the battery.
If there was a way to put the software through SD card, it might solve the problem.
even the software update mode, the computer does not see the phone
Bro! For the softwaretool like smartflash, You need to boot into download mode i.e., You need to switch off the phone, plug in the USB cable connected to the PC and instantly press the volume up button. Then the tool will recognise Your phone. Try it and check once!
I tried it, nothing happens,
I go to download mode, but computer does not recognize it again
behaves as if the port is destroyed

Try to boot your PC with disabled driver signatures, or use a 32bit windows system.
try entering download-mode the following way:
disconnect your phone from pc
remove battery
press and hold Vol-up
connect the usb-cable (still without battery)
Now the phone should be detected as a serial-cable device an you can use the smart flash tool.
would have to be sound,
no sound when I connect the phone to the PC
Solved my problem.
Seems like windows automatically installs driver to the phone, but it partially works.
Unistall all drivers for the phone, or try on a new computer.
Plug the phone and cancel the driver search by windows
Install drivers for LG (unplug the phone before)
Turn it off
Plug the cable and enter download mode
And there is the phone recognized on smartflashtool.
I'm flashing a new one right now, thank you.
You do not understand the problem
there's no sign, no sound when I connect the phone to a computer, any computer, drivers were or were not.
As if something in the phone blocked communication between the PC and phone

Connection Problem with Mackay 2.999
Hey Guys,
first of all, sorry for my not so good English
I'am at Mackay 2.999 with last Kernel of his build and can't connect the Phone to the Computer.
It only install the LGE Mobile Composite USB Device, the LGE Mobile USB Serial Port and the LGE Mobile USB Modem on connecting to the Workstation.
I had test it on many Computers but the Problem is all the same: I can't get on my Memory or ADB.
I also had testet all modes under the setting point (MTP/PTP/mass storage device) and with debbuging on and off.
On my Workstation is the Last Version of ADB (1.0.31) installed.
Did anyone know the problem?
Did no one know a result to this problem
Hmmm my PC also can't read my storage what I did is go to cwm and plugged in usb cable and pressed mount storage it seems to solve my problem. I also did a cache and dalvik cache wipe.
Hey, I have found the result to this problem. You must flash another Baseband. Use from Nooby the V30 Baseband and it is solved.
