If your box is still able to enter maskrom-mode, it will continue to work. I uploaded a new version of the script that also flash the gpt partitions. I hope that's what I missed. You can download it from here: https://mega.nz/#!yLAR3AIZ!1RXrDS-1f_y2M50fSokz5PsLcNRXenAzlhPRU_n_C6o Otherwise, what tool did you use to flash the android firmware? (The script can't do it.)
