The values of all the .bsq files in the images folder are zero

Hi, friend. I'm trying to use this useful tools to detect land cover change in my study area, but in step 7, I found all the values in the images are zeros.
I checked, found that there are values in images downloaded from GEE in step 2, but in step 4, when I tried to execute 'python tsl_gee_stack_unpacker.py C:\mock\timesync\project\prep C:\mock\timesync\project\images timesync_legacy_demo', mistake happend. When the cmd windows showed 'unpacking files', I checked these temporary files, all there values are zeros. And the .bsq files generated after this step are zeros.
I am not familiar with python. Could you tell me the posible reason for this mistake? Which code or step should I change?
I have tried different crs ('EPSG:5070' and 'EPSG:4326') in GEE, but all of the images are zeros.
I also tried the image you provided in the GEE code, and don't know why the cmd window showed 'stopping program'...
BTW, the environment I used is python 2.7 in anocanda.
I am looking forward for your reply! Thank you!
