The bootloader is "the thing" which enables you to download anything via ISP, so of it is "blocked", there is no way how to download anything via ISP and you need to resort to parallel programming (in a device programmer).

However, there might be a chance that you have switched on the "softICE mode" accidentally, which might happen if you choose by mistake P89C51RD2 instead of P89V51RD2 in FlashMagic. Search for "unsoftice".
