Nexbook AMlogic root WORK!

The init-pppd.sh is being setup as a service. To invoke
it, you actually has to start if from a shell, IE "start pppd_gprs".
(the name after service). That being said, I don't think "shell" has
the permissions to start that service. Although if you try, it doesn't error.

service pppd_gprs /system/etc/init-pppd.sh
user root
group radio net_admin cache inet misc
disabled
oneshot

I tried "start pppd_gprs" and didn't get an error, but I don't think it ran the startup script because the files are still not there.

I would like to take a look at the log file, just to be sure, though.

[eegorr]

if you look in the script, you see things like:
/system/bin/log -t pppd "init-pppd.sh SCRIPT=$SCRIPT"

that should log a pppd entry. I don't see anything.

if you "cd /sdcard"
then "logcat -d > logfile.txt"

You can view that file. To prove that is the log, you could also
do :

/system/bin/log -t freaktab "this is a test"

Then logcat -d should show it.

So just doing a logcat command wont work? It should... I did not think you had to be rooted to get the log!

I can run it.

shell@android:/ $ /system/bin/log -t freaktab "this is a test"
/system/bin/log -t freaktab "this is a test"

shell@android:/ $ logcat -d | grep freak
logcat -d | grep freak

I/freaktab( 8536): this is a test

Yep! I just typed logcat into the terminal emulator - no piping or anything.

[eegorr]

I can run it.

shell@android:/ $ /system/bin/log -t freaktab "this is a test"
/system/bin/log -t freaktab "this is a test"

shell@android:/ $ logcat -d | grep freak
logcat -d | grep freak

Are you running from adb?

[biffler]

ya, I execute "adb shell" to get a prompt

[Finless]

biffler, do you see anywhere in the log that the pppd script gets run?

Also can you guys see if you can edit the install-recovery.sh script in /etc/

Might be another way as this runs at the end of init.rc

Bob

[Finless]

Also you guys... try to find somewhere in /data you can write to so we can push su and superuser.apk there via ADB. We will need that if we are to use a script that runs from init.rc. SDcard will not be mounted during init.

Bob

[biffler]

no, it does not show in the log, so I don't think it is runnin. I believe that since the init.rc shows it disabled, it will not run on boot. Only if an authorized user starts it afterwards.

perms on the script:

shell@android:/etc $ ls -l install-recovery.sh
ls -l install-recovery.sh
-r-xr--r-- root root 418 2008-08-01 08:00 install-recovery.sh

Just found out I can run logcat from adb as well, just not from a terminal window on the tablet. I grep'd for pppd and nothing showed up.

I tried to edit install-recovery.sh and got no error when I tried to save it but the file was unchanged when I looked at it again.

[Finless]

This fricken thing is locked down hard! I am sure there is an exploit we just have to find it.

Again since I do not have the device I cannot see what the flash tool is capable of. boot.img is pretty esy to edit and pretty generic. This is where init.rc exists. I could make a boot.img. However if you cannot flash that by itself with the tool, it will be of no use.

Bob

[Finless]

I think I am going to bow out for a while until you guys find other ideas...

Sorry guys... I love a challenge but without this device myself I am guessing at this point.

If you find some new info PM me and I will see what we can figure out.

I won't be able to mess with it for a day or two either, currently stranded on the wrong side of a mountain pass waiting for it to reopen

I noticed the thread for the Latest Nexbook 9P stock ROM as of Nov. 2012, uses Bin4ry v15.zip to root. I also noticed over on xda, there is a v17 of this out. Root_with_Restore_by_Bin4ry_v17.zip. The title of the thread over there is "Root MANY ANDROID! [Upd: 22.11.2012]". It says "it should work on nearly all ICS/JB devices". Just checking if anyone has any opinion or experience with this method. I would hate
to brick the tablet. I know nothing about it, and am in no way suggesting using it.
