# This script works on macOS and Linux only!
#
# Usage:
#  1. DOWNLOAD tsschecker (https://github.com/tihmstar/tsschecker)
#  2. Unzip the zip file and change directory to the unzipped directory
#  3. Copy this file to this directory
#  4. Make tsschecker executable with `chmod +x tsschecker_<whatever>
#  5. SET SETTINGS BELOW
#  6. Run `python3 SHSH_saver.py` from the same directory

# ---------- BEGIN SETTINGS ----------
model = 'iPhone7,1' # your iDevice model

platform = 'NXXAP'
save_path = 'blobs'
