Phoenix seems to be completing successfully. And the blue LED goes off after 4-5 mins...but nothing.


once the power indicator (blue light) automatically turn off..Remove SD Card and power MK802II again.

Try formatting the card completely then run Phoenix card and do the same step for flashing the image..if it still doesn't work try using a diff USB power..try using a USB 2.0 connection or use the USB power adapter..

Mine works ^^

Do you mean using the USB 2.0 connection to a computer to power it instead of a power adapter?

Yes, I have tried 4 times! Is it normal that the only thing on the device after is one folder called "LOST.DIR" and no system folders??

What directory are you looking in? Do you have an sd card inserted? It sounds like you are looking where your external sd card used to appear.

After flashing this new firmware, part of the internal storage is mounted at /mnt/sdcard (which is what /sdcard is linked to) and your sd card is accessible at /mnt/extsd. The only contents of /mnt/sdcard (until some applications write to it) will be LOST.DIR.

Here is my mount table from the new firmware with an sd card inserted.

Code: Select all
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600,ptmxmode=000 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/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
/dev/block/nandd /system ext4 ro,relatime,user_xattr,barrier=0,data=ordered 0 0
/dev/block/nande /data ext4 rw,nosuid,nodev,noatime,user_xattr,barrier=0,journal_checksum,data=ordered,noauto_da_alloc 0 0
/dev/block/nandh /cache ext4 rw,nosuid,nodev,noatime,user_xattr,barrier=0,journal_checksum,data=ordered,noauto_da_alloc 0 0
/dev/block/nandi /mnt/private vfat rw,relatime,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp437,iocharset=ascii,shortname=mixed,errors=remount-ro 0 0
/dev/block/vold/93:80 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/block/vold/93:80 /mnt/secure/asec vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0
tmpfs /mnt/sdcard/.android_secure tmpfs ro,relatime,size=0k,mode=000 0 0


The above is what the build-in filesystems look like with this firmware. If you insert an SD card, you'll also see an entry like

Code: Select all
/dev/block/vold/179:1 /mnt/extsd vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1023,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0


EDIT:

I have put the above at https://gist.github.com/3693508/ for easier viewing. I have also added filesystem sizes, which I'll paste below too.

Code: Select all
Filesystem             Size   Used   Free   Blksize
/dev                   406M    44K   406M   4096
/mnt/asec              406M     0K   406M   4096
/mnt/obb               406M     0K   406M   4096
/system                314M   254M    60M   4096
/data                  503M   147M   355M   4096
/cache                 125M     4M   121M   4096
/mnt/private            15M     4K    15M   4096
/mnt/sdcard              2G    28K     2G   4096
/mnt/secure/asec         2G    28K     2G   4096

I am simply plugging the device back into my computer. Before I did the recovery I had a full list of OS/Android folders. Now after the recovery process I only have that folder ("LOST.DIR").

Huh? That doesn't make sense to me.

Is this what you are doing?

    Flashing the new firmware onto your MK802 II
    Removing the SD Card
    Powering on your MK802 II
    Starting the 'FileManager' app from the home screen
    Selecting 'Local Memory'

Yes, if you are doing what I listed about you should only see the folder LOST.DIR. "Local Storage" in FileManager is showing you the contents on /mnt/sdcard, which is a new empty partition on your internal storage which this firmware update created.

If you want to browse the root filesystem, I recommend installing ES File Explorer and enabling "root explorer" and "up to root" in its settings.

After I flash the new firmware onto the MK802 II there is nothing on the TV screen.
