That assumes you don't also reflash the bootloader (e.g. because the vendor-provided one can't boot from removable media). If you reflash it with a new uboot and you've cocked that up, you could brick it.
How much extra would it cost manufacturers to design devices so that there's a backup boot loader in ROM which can't be overwritten?
My tegra2 had such a thing. It wasn't fun to use, but OTOH I repeatedly bricked my uboot. PS: because the instructions said to build uboot on x86 with ARCH=arm, but I was building it natively so omitted ARCH=arm... which broke it. By the time I knew, I'd given up and was stuck with android bootloader...
