You also need to copy the su binary file into the xbin folder.

Make sure you set 644 permissions to Superuser.apk and 6755 on the su binary.

In Ubuntu, the commands are:


From your working directory:
mkdir mntsystem
sudo mount -t ext4-o loop system.img mntsystem
sudo cp Superuser.apk mntsystem/app
sudo cp su mntsystem/xbin
sudo chmod 644 mntsystem/app/Superuser.apk
sudo chmod 6755 mntsystem/xbin/su

[While you have the system.img mounted, you can snoop around a bit with sudo Nautilus]

sudo umount mntsystem

[This will save your changes and close system.img]

Good Luck!!!!!

In Ubuntu, the commands are: ....

Ok but a have windows 7 x64 not Linux ubuntu,
moby I share my system.img and You add root to my file?

[rrileypm]

I would be happy to help. Just send me a dropbox (or similar) link to the file and I can root it for you.

That being said, let me suggest that you create an Ubuntu virtual box using Oracles Virtualbox program. The distro I really like for developing is Ubuntu Studio...but just plain Ubuntu works just fine.

BTW, what device are you working with? Tablet...TV Stick...? What brand/model do you have?

[t_gumienny]

My device is tv-stick Mk809III

this is link for my custom system.img based on last MK802IV_AP6210_20130905_1080P firmware
Pleas add root to this, i would be very grateful
i Have 2nd problem with default luncher resolution.
My rom is on 720p karnel but luncher work in 1080 I dont know why,but it doesn't prevent for me.

[rrileypm]

Sorry, I'm not a TV Stick guy...have you looked at the threads for the ROM's already available for the Mk809III? There may be a solution somewhere in there. Perhaps even a HD kernel.

I'll root this system.img for you and post a link to it.

[rrileypm]

It appears there is not enough space available within this system.img to add any apps.

What I can do is increase the size of the file system to allow you some wiggle room, but if I do that, you will need to change the parameter file to accommodate the bigger system.img.

Are you prepared to do that? Or do you need help with that, too?

[t_gumienny]

Pleas only add root,
I think can handle it.
Thank's

OK, here is the link to your rooted...and expanded system.img

yhmm superSU show: "there is no su binary intaled and supersu cannot install it this is a problem!"

[rrileypm]

It appears that SuperSU just put out an update.

In Google Play Store, you can update the app...if you haven't already done so. The open the app and attempt to update the binary.

If that doesn't work, I'll add an alternate Superuser app.

[rrileypm]

I've redone the file and I'm uploading it, now.

I'll post a link when it's done. It is the CWM Superuser app.

Hopefully this one will work for you.
