    Hi, i receive this tablet (a gift) like a 2 months.

    resistive screen 7'' - Vimicro cortex A8 1 ghz (VC882)- 512 ram - 4gb memory (no sd card introduced)

    And have a big problem, the INTERNAL MEMORY is not detected by the tablet and by the PC too,
    when i go to settings > storage, the aplication is closed and prompt a error message (FC).

    i cant access to the content by a explorer like ES, when i try this a message tell me:

    "sdcard is unmounted or not present"

    In the gallery i cant view/add/etc. images. Buuut the tablet allow me to install apps from GETJAR market, this is a included market with the tablet...
    i can install apps from a pendrive + usb otg cable, but i cant download anything like images, audio, videos, apps, etc

    How i can fix this? I'm going crazy, please help me

    (note: my english not is so good, i speak spanish and google help me so much to translate this texts, sorry for the grammar)


    UPDATED!!! (26-03-2014)

    Hi folks! i back with good news to fix this problem if you have too :cool:
    Well i search a lot how fix that but without result.
    My solution for this problem is edit the vold.fstab file and create a folder inside of ext-card to emulate the internal sdcard.

    this is the original vold.fstab content for Coby Kyros MID7033:

    dev_mount sdcard /mnt/sdcard auto /devices/virtual/block/loop0 /nfdisk/fat.bin
    dev_mount external_sd /mnt/sdcard/external_sd auto /devices/platform/v8-sdio.0/mmc_host/mmc1

    #dev_mount idisk /mnt/idisk 1 /devices/platform/v8-sdio.2/mmc_host/mmc0
    dev_mount udisk /mnt/udisk auto /devices/platform/vc088x-ehci/usb1 /devices/platform/vc088x-ohci/usb2 /devices/platform/musb-hdrc/usb3


    and this is MY FIXED VOLD.FSTAB:

    dev_mount external_sd /mnt/sdcard/external_sd auto /devices/platform/v8-sdio.2/mmc_host/mmc0
    dev_mount sdcard /mnt/sdcard auto /devices/platform/v8.sdio.0/mmc_host/mmc1

    #dev_mount idisk /mnt/idisk 1 /devices/platform/v8-sdio.2/mmc_host/mmc0
    dev_mount udisk /mnt/udisk auto /devices/platform/vc088x-ehci/usb1 /devices/platform/vc088x-ohci/usb2 /devices/platform/musb-hdrc/usb3


    This vold invert the memorys, i mean sdcard now is ext_card, and ext_card is sdcard. With this u have a sdcard more bigger to install heavy apps and u can see the two storages in "settings"

    Very important!
    • Need Root access to edit system files
    so root with SRSroot using ALL METHODS button, that work for me.


    • Need a SDCARD plugged in on tablet to make this work!
    First plug the SDcard in a PC and create a folder named "external_sd"
    DONT DELETE THIS FOLDER!
    (if you delete this folder, you lost external sd)

    Then put again the SD on your tablet.

    • vold.fstab can be founded at /system/etc/vold.fstab.
    Edit this file with root explorer, Or use ADB commands if you know hot to.
    Give RW-R--R-- permissions to the vold.fstab file and reboot.

    i hope this fix that problem!

    The translation came out ok. I could understand you.

    We need some more details. Did you root the tablet and did you modify any of the system files after rooting? Tell us what you did to get you to this point.

    Spanish:
    La traducción salió bien. Yo podría entender.

    Tenemos algunos detalles más. ¿Te erradicar la tableta y se modifica alguno de los archivos del sistema después de enraizamiento? Cuéntenos lo que hizo para llegar a este punto.

    That spanish is not too good, the real translation :Necesitamos mas detalles, rooteaste la tablet y modificaste algun archivo del sistema, Dinos que hiciste para llegar a este punto.PS: I thinks that is the problem, i was having the same problem, ask for a new one and only install an "update.zip" without modify the system, and until now no problems

    thanks for answer, well no, i never root the tablet, i never modify anything from system, the problem just appear after i do the factory reset, and i do that because is the tablet of my girlfriend and she gift me, so i do the factory reset to have a ''fresh system'' to use, and maybe that is my worst error :(

    when i connect the tablet to pc and press the button ''activate usb storage'', the icon just still spin and the tablet dont do nothing.

    if u want i can pull some files from tablet by adb connection and post here, like vold.fstab or build.prop, because i read (in others threads) maybe i have problems there...

    @samirnge: I don't speak Spanish though to an extent I understand it back from when I was in high school. The translation came courtesy of Google, so if you can improve the translation, I'm sure they'd love to hear from you. ;)

    @SeniorM: If the tablet isn't rooted, you may have a hardware issue. But please do pull vold.fstab and your build.prop and post them so they can be eliminated as the source of the problem.

    That vold.fstab appears to be correct, which leads me to believe you have a hardware issue with the MicroSD card slot.

    Ok, it's been a long day in the real world, and it only hit me now that the solution to your issue is insanely simple.

    Devices running Android 4.x have two storage spots. The first, /mnt/sdcard, is soldered onto the motherboard and cannot be removed. Thus if you disassemble the tablet looking for it, you won't find it. The second, /mnt/extsd, is the MicroSD card slot.

    /mnt/sdcard is where applications store their stuff.
    /mnt/extsd is where you store your stuff.

    By default /mnt/sdcard is set to only allow the system and applications to write to the space in order to store system settings and configuration files. Your access is limited to reading and executing files.

    /mnt/extsd on the other hand is where the user stores all their paraphernalia; apps, pictures, documents, music, etc. Both you and the system have full access to the card and are able to do anything to it, including delete all the files on it.

    You cannot store your stuff on /mnt/sdcard as you do not have permission from the system to write to the space, even when rooted. Your stuff MUST be stored on /mnt/extsd. Therefore, the solution to your issue is purchasing a MicroSD card.

    before this problem appears, i can open some folders like "mnt/sdcard" and view content like ".android" folder and the other folders created by apps. But not now...

    Don't search for solutions. Just get the tablet exchanged, because this is sounding more and more like a hardware problem, not software.

    the 7033 reset is no where near the mic, it's on the back of the tablet between the charger and usb port.
