I just uploaded full 1GB from factory ROW region unit:

Config.ini looks like this:

Description=HDS-5 with Worldwide Background


DefaultTimeZone= +10:00

---------- Post updated at 01:45 PM ---------- Previous update was at 03:12 AM ----------

I found one more thing.
In the dump above, config.ini starts at 0x837C000 and ends at 0x837E93F.
There is no UBI signature in file header.
Other files on NAND starts with "UBI".

Also in I found:

   # Mount the rest of the jffs2 entries
   for FS in $(
      grep " jffs2 " /mnt/etc/fstab | \
      awk '{print $1 "#" $2 "#" $4}'
   ); do
      DEVNODE="$(echo "${FS}" | cut -f 1 -d \#)"
      MNTPT="$(echo "${FS}" | cut -f 2 -d \#)"
      MNTOPT="$(echo "${FS}" | cut -f 3 -d \#)"
      mount -t jffs2 -o "${MNTOPT}" "${DEVNODE}" "/mnt/${MNTPT}"
      #pkill -STOP jffs2_gcd     Don't do this, since the only jffs2 fs left is the tiny config partition so this has no performance benefit
   CONFIGJFFS="$(grep "^/dev/mtdblock${CONFIGMTD}" /proc/mounts | cut -f 2 -d ' ')"

and this..

   ## Bulk file installer functions.
   # Ensure that map types match.
   Chartmatch () {
      # Read the unit's Config.ini file
      ls "${CONFIGJFFS}"/Config.ini >/dev/null 2>/dev/null && {
         egrep -iqs "^havebackground *= *(1|true)" "${CONFIGJFFS}"/Config.ini && \
            UNITCHART="US Background"
         egrep -iqs "^havelakeinsight *= *(1|true)" "${CONFIGJFFS}"/Config.ini && \
            UNITCHART="Lake Insight"
         egrep -iqs "^havenauticinsight *= *(1|true)" "${CONFIGJFFS}"/Config.ini && \
         egrep -iqs "^haveusinsight *= *(1|true)" "${CONFIGJFFS}"/Config.ini && \
            UNITCHART="Insight US"
         egrep -iqs "^haveworldbackground *= *(1|true)" "${CONFIGJFFS}"/Config.ini && \
            UNITCHART="World Background"

Is it possible that one part of NAND is UBI and other part is JFFS?

Bleh, this weekend was a dead loss. Smilie

Yes it's possible. I don't know why they'd bother using both since it's stupid and jffs2 is all-but abandoned in favor of ubi, but it's possible. I'm still trying to get UBI flash images working.

Maybe it is easier to unpack/mount only JFFS part. That part I am interested most Smilie

Old 09-26-2011
Obviously, but one would have to find it first, which means cracking open the UBIFS part.

I can cut it off from "big" dump.

If you're positive where it begins and ends. I'm sure not.
