I have a strange situation with a 2960s. After attempting to upgrade the IOS version to 150-2.SE4, the switch appears to load the image and boot normally, but then seems to fail and start over again to load the image (more slowly the second time). Eventually the boot process fails and leaves you in boot loader mode.
As background, the switch was upgraded from the boot loader mode using this syntax:
Just a guess -- I think your configuration register might be misconfigured. Each of the bits in that 0x3000 entry point need to set correctly otherwise the switch won't work correctly. Based on my research it looks like you need to set the least significant bit to on and it will load the image from flash. So the entry point would be 0x3001. Again, each of the 16 bits in that configuration register has a different meaning, so changing that least significant is only a starting point. Other bits could be misconfigured too. Hope that helps!
