hello,

i have uninstalled uboot for pr 1.3 but still im getting uboot option when i restarting my device, and if i type root or else sudo gain root command in terminal i am getting an error message"root is not in the sudoers file.this incident will be reported."

please help me out of this, as i have to install android gingerbread n12 and im unable to do because of this..
thanks in advance..

The problem (to being with) is that uboot isn't a normal package - like the power kernel, it's a kernel image package. When you uninstall the package, the actual kernel isn't reflashed back to whatever you previously had.

So either reflash the kernel only from flasher (if you want the stock kernel), or install/reinstall power-kernel. The (re)install of kernel power or the manual flashing of the kernel would override the kernel with uboot prepended to it with either the normal stock or the normal power kernel.

I'm not sure if this would automatically fix your root problem - it it doesn't start by reinstalling rootsh.

As Mentalist Traceur said, just use flasher -f -k <zImage> -b either the stock kernel (if you still have the stock kernel headers installed -- I don't.) or extract a zImage from kernel-power-bootimg or kernel-power.

As for the root user problem, remove rootsh and sudser, and reinstall them using FAM/HAM.
Also, you can't gain root when you're already root. Are you sure you aren't already root?
