Sadly, this gets repeated over and over:
If you upgrade past MDK, you can't bypass the bootloader, which means you can't install custom recovery or custom kernels.
Once you install a release, you usually can't install any prior release (the only exception is that MK2 can be downgraded to MJ7).
My Android devices:
vzw Samsung Galaxy S4 stock MJ7, now rooted!
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
