whoa...quite simple...thanks bro...but i seemed to read somewhere that everytime our phone reboots, especially for Samsung phones, it will read everything back from the boot.img, so as this exploit is quite simple, will the root stick? sorry for the crudeness of the question...im quite a noob in android development as well..haha...

If using a root browser such as root explorer i make any changes to the files in the boot partition such as init.rc or default.prop then the changes will not persist after a reboot as the phone reads everything back from the original boot.img.

But if we change the the original boot.img(that is what we are doing here) and flash it then the changes will persist.

i see...thanks for the explanation...good job with the root guide for Ace Plus...

To qzem, yeah...im quite as much noob as most of the users here in xda...but maybe we have to do this in a Linux environment, cos i read somewhere for ROM making, its quite difficult to use Windows... now for me, rooting our Galaxy S Advance is quite probable, just that learning how to use Ubuntu just for making these exploits is quite unnerving... there are quite thorough guide for unpacking and repacking those .img files, but you have to be familiar with Linux...

First unpack the stock boot.img of your device.
Then open the default.prop file and set
ro.secure=0
ro.debuggable=1
persist.service.adb.enable=1
and save the file.
Now repack the boot image and tar it.
Then you can flash it via Odin
The changes give us root access to adb shell and we can push the su binary and Superuser.apk via adb.
But if you are lazy then run any of the available rooting tools which copy the necessary files via adb(eg Doomlord's toolkit)

How to unpack and repack boot.img? Is there any useful guide here. Can I pull boot.img straight from my phone or can I extract it from firmware (.tar file) on my pc, and how? Or do I need kernel source code, to compile insecure kernel? Thanks for your help!

now i have definitely run into some confusion here...your guide in remaking the boot.img is very clear, but the problem now is that i can't figure out where is boot.img located in Galaxy S Advance firmwares...all i have are system.img, cache.img, hidden.img, kernel.bin and modem.bin... is it in the kernel.bin? if so, how do i extract it?

Im not sure but i think unpacking tools are same as boot.img.There are many guides available online

i see...how do u manage to get CWM working for Ace Plus? do we have to root 1st for flashing CWM, cos i remember that it is not necessary... what are the files we need to port CWM to other devices?

Thanks for the CWM , now all we need is some custom ROMs , hope some developers step in....
