Help! Cannot go into mass storage mode - LG Optimus 3D

I was trying to test a new rom out and when i finished installing it everything just completely fails. When i connect my USB in, mass storage dosent appear so i cant add a rom that i know that works on my phone (and i dont have a backup) . Anyone knows a way to fix it?
Also, when i try to open settings it just crashes same with messages.

Do u have an externel sd card to put a rom on?

go to Settings -> SD Card & Phone Storage -> mass storage only
that should enable you to mount the memory as mass storage.

I'm having this same issue and I am using CM7 nightly. Is there a problem with this?
i keep on having the same problem and the hdmi wouldnt work either so i had to put i put it back to ota stock gb...and now usb mounting works but hdmi still no good
I have same issue with Cyanogenmod. When it happens go to Settings > Application > Development and turn on USB Debugging. Then it detects and mounts it.
Has anyone figured this out? My G2X won't mount to my computer. the phone recognizes that it's charging, but thats it. It doesn't even give me the usual mount settings. I've installed the LG Drivers and nothing.
Btw the phone is not rooted, and running stock 2.3.4
Thanks!

[Q] How to use both Internal SD and External SD

First I have to say thank you to all the developers for making many great ROM. Second, I am not good with android .
I just upgrade to hellfire sandwich and seem like whenever i choose using"internal storage" the phone will auto gray out the external SD card (8gb). When i uncheck that option, i can use the external SD card again. But I want to use the left over internal storage 5gb too... not just 1.5gb internal storage.
Is there someway to re-partition the internal storage together? or allow the phone to recognize all the partitions?
Another question is I cannot use USB mass storage anymore, that option is grayed out too, And the only option is MTP which work really slow but a bit better than PTP. I need some help because Android commander cant recognize the device and the transfer sped is pretty slow.
You should be able to access the internal storage by navigating in the file explorer of your choice to the mnt/emmc/ directory. As for the mass storagw, I don't know the answer, but I had that problem too while I was on ICS.
The best option I have found is to use cwm to add and remove things through storage. It works all the time. Since on 2.3.3 mounts where sketchy and I've never been a fan of mtp on ics this is what I've always done.
Your transfer rates are due to your SD card class. The higher the class the higher the read/write speeds.
Ics went to using mtp and ptp instead of USB mass storage. Except there's a few roms that have hacked ums in and got it to work or claim too.

Yes i can do that too, so there is no way to allow the phone using both... I want to let the phone install apps to internal, and use external as media storage.

Thank you, because i saw the option there so i just wonder if there is a way to enable it... but if it not supposed to be there then there is no help.
If you go to ../etc/ using a file explorer, you may edit vold.fstab using a text editor and change manually your SD cards mount points (dev_mount emmc "folder location" for internal SD and dev_mount sdcard "folder location" for external SD)

Ok, well in your SD Card you shoud see either _Internal SD or _External SD when you go into CWM, installing a rom partitions you SD card normally using EXT4. You can navigate to both through mnt in file manager. Normally it'll load into external. You can go back to mnt and go into internal through there. Now, you may have to unmount and remount so you have access to it. If your using hellfire 1.7 you need the updated harsh kernel to access USB storage. In 1.6, however, you shouldn't have that problem.

Mounting internal storage as USB mass storage

Hi Guys, is there a way to mount the galaxy s3's internal storage as a USB mass storage device? As you know, currently when you connect to the computer, there are only two options: MTP and CTP. I know there is an app that does this for the external SD Card but I need it for the internal storage.
Thanks!
I use an app called SambaDroid. Once you connect to your phone you can map it as a drive using Windows. I use SyncToy to back up my stuff regularly, and although it's a lot of steps, it works pretty well.
If anyone has found a less labor intensive method, I would love to hear it.

Hi everybody, i am a new member (a noob) so i really need your help. I am using a Samsung Galaxy Wonder GT-I8150, i rooted it and flashed the cm9 rom using cmw recovery 5. Now when i want to download something or take a picture (i installed a camera app because cm9's camera is not working) it tells me that i need to insert my sd card. I go back to cmw recovery 5 - Mounts and Storage - Mount Usb Storage, it says: Usb Mass Storage Device Leaving this menu unmount your sd card from your pc. I tried using this option while my phone is connected to the pc but nothing happens, any help plz?:crying:
Maybe, you should try to format sdcard.

It could be something as simple as your SD card being not properly inserted into the slot - maybe because you accidentally dropped it. Try opening the phone's back and removing the SD card and then reinserting it. make sure it properly sits in its slot. If the problem still persists, wait for someone with better knowledge to come along.
