One more thing:

Code: Select all

cat /mtd_rwarea/passwd
root:saJvQKUdIxRW2:0:0:SamyGO secured Root::/mnt/bin/ash
Your "HOME" is empty (::) I believe this is because there you used NEW_HOME nad never defined it...
Therefore change this:

Code: Select all

        if [ ! -e /mtd_rwarea/passwd ]; then
                echo "root:saJvQKUdIxRW2:0:0:SamyGO secured Root:$NEW_HOME:$SYSROOT/bin/ash" > /mtd_rwarea/passwd
        fi
to this:

Code: Select all

        if [ ! -e /mtd_rwarea/passwd ]; then
                echo "root:saJvQKUdIxRW2:0:0:SamyGO secured Root:$HOME:/mnt/bin/sh" > /mtd_rwarea/passwd
        fi
then

Code: Select all

umount /mtd_rwarea/passwd
rm /mtd_rwarea/passwd
reboot and post the result of this:

Code: Select all

cat /etc/passwd
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on https://pastebin.com Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!

First of all you have /mnt/bin/sh:

Code: Select all

lrwxrwxrwx    1 root     0               16 Nov 11  2013 /mnt/bin/sh -> /mnt/bin/busybox
. Always use this. Don't use /bin/sh!!!
Secondly you didn't run and/or didn't inform me that this command failed:

Code: Select all

ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/opt/privateer/usr/sbin/dropbear
If you keep on giving me wrong information and not doing what I ask we won't get far... Fix it!!!
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on https://pastebin.com Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!

Yeah now I know... But If you would have done it at beginning we would already finished... Run this:

Code: Select all

rm /mnt/opt/privateer/usr/sbin/dropbear
ln -s /mnt/opt/privateer/usr/sbin/dropbearmulti /mnt/opt/privateer/usr/sbin/dropbear
ls -l /mnt/opt/privateer/usr/sbin/dropbear*
dropbear --help
ls /mnt/etc/init.d/
Post the results.

Reboot and check if ssh works :)
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on https://pastebin.com Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!

Permission denied, please try again.

ps aux | dropbear
You are doing something wrong... You had this error previously and no drop bear was even running... What do you use for password?
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on https://pastebin.com Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
