prepare a stock TF1.img (on macOS)
/dev/disk4 for me (use `diskutil list` to identify correct devices)
add ` && say done` to commands that take a while for audio feedback upon completion
download the official release or backup a fresh stock sd card
https://drive.google.com/drive/folders/1HfGCxkratM_zYiYfGWCrHZ1AynO3hIwU (last updated 2023-03-09)
flash the initial img to a new card
use gdisk to delete and recreate partition 4 (ROMS)
set End (sector) to +3G
full instructions https://pastebin.com/raw/YV1Va5JL
erase the ROMS partition in Disk Utility
rename partition 1 to MISC if necessary
zero all free space on the accessible parititions
diskutil secureErase freespace 0 disk4s1
diskutil secureErase freespace 0 disk4s4
delete all stock folders on the ROMS partition
delete all hidden macOS files and folders on accessible partitions
unmount and use dd to create a clean image (use rdisk* for faster raw reads)
sudo dd if=/dev/rdisk4 of=TF1-raw.dmg bs=1m count=1152
removing trailing null bytes
python3 -c "open('TF1.img', 'wb').write(open('TF1-raw.img', 'rb').read().rstrip(b'\0'))"
zip img file (macOS Compress contextual menu is somehow smaller than command line)
