[Q] boot loop after flashing baseband topic

tonight i decided to update my rom from Danvdh's 4.3 GPE to his 5.0 version. the update went flawlessly but i felt like wifi was a very slow. i decided to flash my baseband from mk2 to nh7. now, rather than seeing the lovely 5.0 bootup animation, my phone endlessly plays the tmobile bootup animation. i can't boot into recovery but i am able to boot into download mode

what was the problem with what i did? and what can i do to fix it?
