KLOTS provides an easy firmware flash feature. To install the leJOS NXJ firmware connect the NXT with the computer via USB and turn it on. Then select //Window->Preferences->KIELER->Lego execution->Firmware flash// and follow the instructions. You do not need to set the NXT brick in firmware-update mode, although doing so may help in case you are getting errors during the flash procedure. The whole process should not take more than a minute and after that the new firmware is permanently saved on the NXT's flash memory, so that the original Lego firmware is fully removed. If you want to remove the leJOS NXJ firmware and switch back to the original Lego firmware, you have to flash it on the NXT brick.
