This is a script used to unpack and pack the PUP dev_flash the team using tools fail0verflow, kakaroto geohot and, although modified a bit for better performance.
Instructions:
* Put these tools in a folder called flash-Des-Emp_dev
* You need to have unpacked the PUP
* Extract the files in the folder update_files.tar script
* Run the script and ready
Notes:
This script creates 3 folders dev_flash, dev_flash_temp dev_flash3 and the first two are simply dev_flash fully unpacked and the third is the creation of folders dev_flash .* files, this could change what you wanted (I AM NOT RESPONSIBLE FOR ANY DAMAGE THIS TOOL MAY CAUSE) and modify the script to skip to step packaging.
WARNING:
I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT THIS TOOL MAY CAUSE, SO BE VERY CAREFUL
