[Q] USB mass storage not working anymore - LG Optimus 2x

Hi all,
I've flashed rusty's CWM, temasek's kang and vadonka's kernel all in a row... unfortunately now when I plug my O2X to my PC it's not recognized It appears in device manager with the yellow exclamation marks and I can't seem to get rid of that.
Any ideas?
Thanks!
EDIT: Ok, reinstalled all drivers and everything, now it's all pretty, but I still can't get usb storage to work. In cyanogenmod application settings if I have internal storage ticked it asks me to turn on usb storage but then nothing shows up in my pc. If it is unticked nothing shows up to turn on usb storage... Also, no matter if it is ticked or not I can't get the camera to work...

Tick and untick usb debugging while usb is plugged in and then in device manager, click on scan for hardware changes and whatever comes there with yellow mark, click on update sftware>update automatically and it should automatically load drivers

Thanks for your reply.
I've reinstalled everything and now it's detected ok, but I still can't use usb storage. And I can't get the camera to work. I edited the first post.

Well... had to use an actual external card... put in the new temasek's kang and the new vadonka's kernel LOC 48 DS, factory reset, flash ROM, another factory reset, flash kernel, and voila.
Now it's working again. Let's hope it stays that way

[Q] Problem with USB Storage

Hi, I got a problem with the usb cable...
Tried all usb ports, tried with other computers... nothing helps.
The computer detect the nexus one, no problems.
When I Turn On the usb storage its recognize the SD card, and I can get into the SD, also I can delete files but when I'm trying to copy files (to SD) seems like its start copying the files but then stops and its get out from the usb mass storage mode.
I tried this also:
http://forum.xda-developers.com/showthread.php?t=613217
Also, tried to uninstall the drivers with USBDeview [http://www.nirsoft.net/utils/usb_devices_view.html], and install again with the new drivers...
also reset the computer / nexus one ...
still same problem...
any suggestions ?
The problem might be with the cable ?
I tried it also with at least 4 other PCs, none of them detect the nexus via this usb cable, except of 1 that had the problem above.
I had the same problem as you with CM7, are you using Cm7 or any other custom rom?
If i put the phone in airplane mode the transfer was always succesfull and didn't get out the usb storage mode. Then i disabled it and tried it again and failed sometimes. I noticed that everytime it failed i got a message (notification) so i found out that the problem was in the notification. so when the app is on sd and android wants access to the app it will disable the storage mode en grant access to the sd.
This only happend on custom roms, after flashing stock rom everything was fine again.
If you have the same symptoms as me you can try to transfer a file in airplane mode and maybe, if you on custom rom, try a stock rom.
Hope this will help, goodluck
Thanks for answer mate.
I'm with Geo rom, I tried the Airplane mode but nothing change..anyway, I also tried 2 usb cables of friends who have Galaxy S, and it both works just fine!
Seems like the problem is with the cable, so I order 2 new cables.
Thanks again for the help!

Internal Memory and Memory Card not showing up on the computer

Hello guys,
I had CM7 running for a while because of its stability. However, I have used CM9 as well for a long time on my P990. Today, I was planning to revert back to CM9 and connected the phone to the computer but the internal memory nor the memory card shows up in my computer. I tried two different laptops and also reflashed cm7 which was already present in my memory card. Still no luck.
When I connect the phone, I get the bell, alert or whatever you want to call it from windows that it has detected that a usb device has connected. Though nothing shows up in my computer. USB Debugging is switched on. And I also press the notification on the phone which should allow me to transfer files between phone and computer.
Im out of ideas, please help.
Re-install the LG USB drivers, found here in the developers section.
I had the same problem when I flashed my phone and everytime I changed roms, I would have to install the drivers again.

And if reinstalling the drivers does not help for whatever reason, and if all that you're trying to do is to push the CM9 rom files from your PC to the SD on your phone, then try following the tip from XDA-TV using SSHDroid. It worked well for me.

The example in the video is with a Ubuntu machine, but you can follow the same steps for using PC with Putty and WinSCP.
And I haven't tried this, but another alternative is using adbwireless available through Play:

Cannot connect to Mass Storage Mode

Everything was normal till yesterday ,i mean when i connected my phone to pc by usb cable it used to ask if i want to charge or connect in mass storage mode
But today when i connected my phone it didn't gave any notification and just kept charging
i have tried changing the usb ports
tried re-installing the drivers
checking and unchecking usb debugging mode but still it doesn't work
any help will be appreciated :good:
First thing to do would be so to Settings > SD card and phone storage settings and try having mass storage only selected.
If you have rooted ur phone u can try mounting USB storage from the advanced menu of CWM in order to see whether it is a hardware based issue or an issue isolated to the ROM.
If you have the android sdk installed, check whether ur PC acknowledges that the phone is connected to the USB port by typing "adb devices" in cmd. This will tell you whether the PC actually knows that there is something plugged in.
Final thing to do would be backup in CWM and reflash stock ROM then revert to backup.

Can't connect to pc

Hey, Sorry if this has been answered before but anyways;
I just rooted my streak 7 and put on the ICS Beta5.0.1 ROM. Now when I plug it into the PC nothing happens, it still charges fine, but nothing in the way of seeing the storage device in My Computer.
Is this a common problem with this build? (I didn't see anything about it in the build notes)
If not any ideas on how to fix?
If it is, what are some alternatives to accessing the internal memory? I want to put on Gapps via CWM, but as far as I can tell CWM only reads update zips from the internal memory... (If I'm wrong about this please correct me)
Any help would be great
Cheers!
Not sure if MTP is broken on that build or you may have to install drivers again. No, the only way to install Gapps is from CWM or TWRP. On the other hand a factory "Update.pkg" can only be installed from a factory recovery, CWM/TRWP can't do it.
Whoops! All must be done from an external SD card!
You need to possible reinstall drivers.

So I went into device manager and uninstalled the device.
Unplugged and plugged back in and it comes up as an 'MTP USB Device' under 'Portable Devices'.
So from the ADB drivers zip I pointed it to install the MTP driver (tried the ADB fastboot driver too but it wouldnt allow it).
It starts installing the MTP driver but it fails. The reason it gives is: 'This device Cannot start. (Code 10)
What OS are you running even?

Win7 64
I've only tested 5.0.1 for a couple hours, but MTP isnt particularly reliable on it.
Put gapps on an external sdcard and flash from there.
Yeah CWM (V6) doesn't recognise my external SD card for some reason. tried a couple of different cards too...
Anyways I just flashed back to stock 3.2, reinstalled PC drivers, put Gapps on the internal flashed back to ICS and loaded gapps through CWM. All is good.
Still won't connect to the PC on the ICS rom, but that's okay for now. Got everything I need.
Cheers.

[Q] CM 10.1 MTP Problem

Hi,
First of all: I thought I could use USB mass storage in CM 10.1 before I installed it yesterday. Now I know that it is not possible right now and I have to use the MTP option. The problem here is that it does not work correctly and I don't know what to do. When I connect the P880 to the computer using USB I can access the P880 as "portable device(s)" as usual with MTP. Then I click it and it is always empty. I copy files on it which works just fine, but the next time I connect it to the PC the folder is empty again, although the files are copied into the /sdcard folder and they are still there (I see them on my phones Explorer). One thing to mention is, that I cannot copy folders onto the device which are already there (tried to copy "Music" folder and got an error). The error message then is: "Cannot copy Music\n The device has either stopped responding or has been disconnected".
Does anyone have the same problem?
Did you check whether ADB debugging has been turned off before using MTP?

It was on, but now it is off and I still have the same problem. I did not know, that such a thing happens when USB debug is turned on. Why should it?
For me it works fine with the 24.04.2013 build from CM website. :-s Just flashed it and works perfect, try flashing the latest CM.
that was the problem of first nightlies. swapping two memory storage and in the case u didnt have sd memory card, ur internal memory would be empty. updating to latest nighly will solve it.
I am never able to connect my phone via USB after upgrading to CM. So I use wifi file browser and transfer files.
