Hello! I have a big problem. I'm trying to install a new baseband on my o2x but I just can't connect it to my computer. The phone starts charging when i plug the usb to the computer but I just can't enable usb mass storage (the menu never pops up, it only charges). The computer of course does not recognize the phone either. I tried plugging in my old HTC legend and the usb mount worked flawlessly. I'm currently running the MiUI pre release (celebration 2.0) on my o2x but I tried the latest cm nightly aswell as Slick2g-v4 and the problem remained. I installed the LG united drivers, rebooted both phone and computer but still no luck.. Any ideas?
I'm greatful for any help (already seriously considering throwing my phone in a nearby lake and getting a SII -.-)

if youd read the miui thread at development, there is a problem with mass usb connection, usually if your coming from cm, your ext sd is not linked correctly, _extsd something folder from internal, thats why your phone does not recognize your sd card, hence it cant mount
@droweed: Hey Even i'm facing the same problem on Optimus 2x CM7
I understand that the SD is not linked directly dats y its not getting detected..
So can u tell me what can be done or atleast point me in the right direction
Alright : / but shouldn't the phone be able to mount the internal sd at least?

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!
as title: when i connect my OB to PC by USB cable (in USB mass storage mode) the mass storage setup fails! (i use nova v8 rom, but until 2 or 3 weeks ago everything works correctly, and i don't change anything!)
anyone can help me?
Try reboot

ehm...i've already tried 2 or 3 thousand times XD
It might sound silly, but did you ensure that you have Debugging mode enabled on the phone ?
Check to see if Settings->Application->Development->USB Debugging is checked or not.
it's not checked
have you tried reinstalling your ob drivers?¿
Are you using the original cable?
Envoyé depuis mon P-970
i've reinstalled ob drivers many times
i'm not using original cable, but i tried 3 micro usb cables and no one works
mm but do you mean that some programs like pc suite doesnt recognise or just your pc doesnt recognise your ob?¿
i mean i cannot browse ob sd card with explorer

Hello everybody,
I've got a problem with my optimus black.
I flash this ROM http://forum.xda-developers.com/showthread.php?t=1984246, but I'm not satisfied of it and I'm want to reflash the V20N with smartflash tool.
But when I put my phone in S/W Upgrade mode my windows said USB Device not recognized.
I've done this twice:
- install/uninstall usb driver and LG Pc suite
- change usb cable
- change usb port
- change ROM
Nothing work I thing that my bootloader is corrupt because it's modified in the V28c.
Thanks for helping me

What version of Windows?
What version of USB Drivers? Try newer drivers.
Bootloader isn't be changed by flashing ROMs in CWM. ROMs only need to change from boot partition and upwards since thats all they need to change.

What do you mean by software mode ? You mean when the phone is wake up and i'm on Lg Home ? Because when I do it smartflash doesn't find my phone, but windows yes. I tried also to use the SOS recovery mode of B2C but it said that my software version was up to date so it did nothing.

I tried on windows 8 and 7. On twice I downloaded the newest driver 3.7.
I think a problem of bootloader because I flash the old version of V28c, with the .bin and .fls which had CMW inside, It was befor they release the .zip version. It's rewrite the bootloader no ?. And also because my phone doesn't wake up when I push on power button on the V28c, V20G, and CM10. I can only flash it because of rom manager and nandroid backup.
Thanks for help
Solved
After 2 day on this @"#[email protected]# phone, I find a solution work only on widows 7:
With the usb recognition I succed with this protocole,
1) Uninstall the Lg driver
2) Install the driver with B2C
3) Put the phone in S/W mode with the battery windows will say that it's not recognized,
4) Unplug the phone It will stay on S/W mode
5) Reboot Windows 7, and as soon as the desktop finish to load plug your phone
And miracle it's work. Sometime you need to do it 2,3, or 10 times.
Concerning the power bouton it still desn't work on V10A, V20N.... So I think it's broken, so I will exchange it with my operator.
Thank a lot for people who gave me some time.

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

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.
