Install zImage on Android 2.2 devcie How do I install zImage on Android 2.2 device? I have one galaxy tab 7.0 and one NVIDIA Tegra 250 delvel kit.

I was trying to using fastboot on NVIDIA Tegra 250 but I failed.

I could load zImage using following command

fastboot boot zImage 


The device shows that it downloaded the image but nothing happened. If I forced to restart then the kernel wasn't updated.

As for the Gallaxy Tab, I was trying to load the zImage with odin. But the input format should be either .tar or something else not the zImage. 

I have been trying to figure this out for two weeks and I am still stuck. 
I will be very appreciated if you guys could help with that.

Thanks in advance..
The Odin-able kernels for my Galaxy S are simply the zImage in a .tar file.  But the zImage has a peculiar format, and I believe it's specific to Samsung devices.

I would assume that either the kernel you've compiled is the wrong format, or simply doesn't work and the system is restoring the stock kernel from the recovery image.
