    Apad A8 imx515
    I updated my tablet firmware with [ROM] XAUMOD Firmware for 2 speaker APAD IMX515 (modded for Two Speaker, Clone) - modified by @tekowasky based on firmware for one speaker @xaueious.

    My tablet have 2 spekers, no screws, no camera, Freescale CPU 800MHz ARM Cortex A8 1Ghz RAM-512Mb, FlashROM - 4Gb -I think type is FRF85B.
    Additional is inserted TF card 8Gb as "extsd"

    After update procedure I encoutered one problem relating storage devices.

    Initial internal FlashRom 4Gb [which was accessed before as SDcard] can't be accessed at all after this update -only additional TF card [8Gb, [initial accesed as "extsd"] can be accessed now with new name SDcard.

    I have supposed that extsd name was reverted with SDcard but when I try to access [from FileExpert] extsd appear message "Can not access this folder".
    There is any posibility now to access built in storage FlashRom 4Gb or is lost forever ?? - ()

    Edit Later
    I found in file /etc/vold.fstab following lines.
    #dev_mount sdcard /mnt/sdcard auto /devices/platform/mxsdhci.0/mmc_host/mmc0
    #dev_mount extsd /mnt/extsd auto /devices/platform/mxsdhci.2/mmc_host/mmc2
    dev_mount sdcard /mnt/disk auto /devices/platform/mxsdhci.0/mmc_host/mmc0
    dev_mount extsd /mnt/sdcard auto /devices/platform/mxsdhci.2/mmc_host/mmc2
    dev_mount udisk /mnt/udisk auto /devices/platform/fsl-ehci.1/usb

    Commented lines [#] are initial allocation between devices and mounting points.
    But in my tablet folder /mnt/disk don't exist.
    Can anybody to advice me what to do ?? - is correct to change here dev_mount sdcard /mnt/disk .... with dev_mount sdcard /mnt/extsd.... and FlashRom content to be accesed from mnt/extsd???
    Could be bricked my tablet with this change ??


    Thank you in advance,

    Except a.m issue, modded firmware is very good - device run smoothly and touch shaking is dramatically reduced -at least for me.

    Apad A8 imx515
    Finaly I found solution to change permission for file /system/etc/vold.fstab.
    First, root tablet - I have used z4root [permanent root]
    Use Terminal aplication or ADB or QTADB (QTADB run under Windows) for Android/Linux commands
    I have used Terminal app.- bellow is shown Terminal session - black bolded words are commands.
    $ export PATH=/data/local/bin:$PATH
    $su
    # mount
    rootfs / rootfs rw 0 0
    tmpfs /dev tmpfs rw,relatime,mode=755 0 0
    devpts /dev/pts devpts rw,relatime,mode=600 0 0
    proc /proc proc rw,relatime 0 0
    sysfs /sys sysfs rw,relatime 0 0
    tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
    tmpfs /mnt/shm tmpfs rw,relatime,size=1024k,mode=777,uid=1000,gid=1003 0 0
    /dev/block/mmcblk0p2 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
    /dev/block/mmcblk0p5 /data ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
    /dev/block/mmcblk0p6 /cache ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
    /dev/block/vold/179:9 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
    # mount -o remount,rw -t ] ext4 [color="#FF0000] /dev/block/mmcblk0p2 /system [/color]
    # chmod 777 /system/etc/vold.fstab
    #
    Now vold.fstab is allowed to be edited - with ESNote for sample.
    Short description - first log as Superuser with su, than find /system partition with mount, than do /system as "rw"[read/write], than change permissions for file vold.fstab with chmod.
    I have changed in my vold.fstab line,
    dev_mount sdcard /mnt/disk auto /devices/platform/mxsdhci.0/mmc_host/mmc0 - mnt/disk wasn't in my device
    in
    dev_mount sdcard /mnt/extsd auto /devices/platform/mxsdhci.0/mmc_host/mmc0
    Save changes done in vold.fstab.
    Reboot device and FlashRom is now available with name "extsd".
    Problem was that "dev_mount sdcard" was pointed to an inexistent "mounting point" /mnt/disk
