    You deleted all of those things? Please tell me you chose selectively which ones to delete. If not, you deleted a lot of the core functionality for your phone, like the Phone.apk itself.
  5. nectariepv

    nectariepv Member

    No! not all! just the apps with "yes" (and not all those) like this:

    Calculator.apk
    com.android.calculator2
    yes
    61644
    Calculator app

    I think I accidentally deleted an app but I do not know which one. Because at some point my phone move very hard when I delete the apps and in the some point he asked me 2 times if I'm sure to delete the app.

    And do not know which app is for USB mass storage.

    Please help me! :(

    I found an interesting app: Root Toolbox. The menu has submenu "Mount" and when I squeeze it shows "USB Mount Option". Here i found: SD Dual-Mount, Unmount SD from PC, Dual-Mount EXT,Unmount EXT from PC.

    Does it help me?

    You have crippled a good bit of functionality of your phone and are going to experience a great deal of problems going forward as you have seen already.

    My recommendation would be a complete factory reset and do a good deal of research before actually removing anything.
  8. nectariepv

    nectariepv Member

    to reset from Settings menu?
    and if I reset the phone all the system app will reinstall alone
    by themselves?
  9. lunatic59

    lunatic59 Moderati ergo sum Moderator

    The system apps should be installed, but you will have to re-install any apps you added from the market.

    Now that you reset the phone, you should be able to connect it to the computer via USB. Can you verify that it works? I want to make sure your original problem has been solved before we move on.

    If you can connect the phone to the PC, you can browse the SD card with your computer. You'll need to re-download a file browser app in order to browse the SD card from your phone.

    I'm not sure I clearly understand all that you are saying. Please try to make your posts clearer, and ask specific questions if something isn't working.

    I reset to factory settings and I was able to connect to the internet but still can not connect to the PC via USB.

    I found an app named "Root Toolbox" and is there something like:

    USB mount option---Dual Mount SD, Unmount SD from PC, Dual Mount EXT.

    Is it useful?
  18. amlothi

    amlothi Well-Known Member

    Connect phone to PC. Then, drag down the status bar. Look for the notification that you are plugged in. Press it, and select to mount as USB storage.

    If that doesn't work, there isn't an app that's going to help you do it by some magical way.
  19. nectariepv

    Is it possible you need some special drivers for your device? I'm not sure. Mine just works.
  22. nectariepv

    nectariepv Member

    At first when I bought the phone the USB mass storage works fine. But when i deleted some sys app....:eek:
    I tried with all drivers.

    Friend, I understand your predicament. I bought my wife an optimus black , and rooted it in anticipation of some gingerbread rom.
    Then i found out that Mass storage couldn't work !

    Anyway, the problem is because of ROOT. When i unrooted the phone (i had rooted using gingerbreak), the Mass Storage worked again.
    At this point of time, there is not much benefit to rooting since there are so few ROMs/Kernels to flash.

    Hope this helps.
