Cannot connect to Mass Storage Mode - LG Optimus Black

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.

SD Mounting Issue

When I plug my phone into my computer with my USB cable it is not recognized. I have tried multiple computers to see if it might have been the computer, but this did not fix the issue. I also tried a friend's Hero with my computer and his connected fine...so it must be my phone.
I have also checked to make sure that Disk Drive is the default option when plugged in via USB.
I have also made sure that USB Debugging is on.
I have restored to a stable Nand backup with still no luck.
I am on Fresh 2.1.1 with the latest Sprint radio.
Any help would be much appreciated!

USB mounting problem

I connect my phone via usb after rooting. It just says USB connected. I cant choose to mount sd card. Anyone experiencing the same problem ?
You have to go to Settings -> About phone -> USB Settings and choose "Mass storage". Sometimes when I reboot my phone I have to select that option to get mount working again. Probably a bug.
Mine is already in mass storage mode.
Solved the problem by checking USB Debugging mode and downloading Samsung USB drivers for mobile phone.

[Q] Help, I cannot write to my external microsd [SOLVED]

I don't know why, I'm in mass storage mode and I expected to just be able to copy and paste files like in Samsung Wave (or any other phones) but I cannot do it in Galaxy S.
Never liked mass storage mode. Enable USB debugging mode instead. Go to menu ->settings ->Applications -> Development -> USB debugging. Once connected to the PC, pull down the notification menu and select connect.
Thank you. Tried it but it doesn't work too. The micro sd partitions do not appear even if usb mode (debugging) is connected already.
Am I the only one experiencing this?
did you pull the notification bar and choose to connect to ur comp? if ur on froyo, once you click " mass storage " you should then see a green android on the screen with the option to connect to the computer. if you dont see the notification, unplug the usb and try again.
SOLVED after updating my firmware to JPU. Thank you for the help guys! It was as I suspected. For some reason, my phone owned the external microsd's filesystem after formatting (I was using JP2 firmware). I formatted it again after flashing to JPU and voila, all problems fixed.

MTP issue

Hey,
I have a problem here, my device (SGN) isn't working properly in MTP mode, the thing is when I connect my phone to PC with a USB, SD card works fine and is read properly, the problem lies in the phone's internal memory, as soon as I open it up, the folders pop up which are in it, but when I open my "Music" (a folder in internal memory) my Windows explorer's top-bar shows green loading (as if it is reading files in it) but no files are shown up. And it was working fine in MTP mode this morning.
1. MyFiles in my phone reads all the files and folders properly as if there's no issue.
2. I have not rooted my device, it's the plain vanilla ROM, with no changes in it.
3. I tried to use my phone in mass storage mode, by going into "Settings > USB utilities > Mass Storage" and that way it works perfectly fine.
EDIT: Now it's not even detected when I connect it to PC in MTP mode, and there's no issue with my laptop as it is acting the same problematic way in my other PC.
Un-install the MTP USB drivers and reinstall it again. or try with other USB ports.

[Q] Enter USB Debugging with broken screen

Some time ago I dropped and broke my Samsung Galaxy S, I've since gotten a replacement but there are still some files on the internal SD that I want to recover. I should be able to do this with ADB - but USB debugging doesn't seem to be enabled on device.
I thought entering recovery enables this - but I'm basing this on my cyanogenmod 10 install on my working device, whilst I should have stock 2.3.6 installed on the broken one (this rom specifically).
I believe I have the stock SGS recovery, but I can't say for sure.
Anyone have any clue on what I could do to get usb debugging working either in the OS or in recovery?
depending on what CWM you have installed you can go in mount and storage and there mount USB storage....then it connects the internal SDcard to your pc.
On my windows pc, sometimes the internal sd card mounts to pc only with connecting the phone to it. I am not sure anymore under what circumstances i got this working. Perhaps it was in download mode or in recovery mode....also could be that this was when i only short press the power button when phone is down but USB connected.....and if i remember right it depended also on which driver were installed and that sure kies is not running....but perhaps you give it a try?
