Should I download a lot of downloaded things every time I wangt to boot?

As I wrote in the title, I have this question.. Can I use the file that has been pyboot once to boot directly without downloading later?

It's a great tool to use, especially Vieux. I've used it more than 40 times (every time I brush my machine for some reasons...). In addition, I found a perfect one (it's a little trick, because if I don't, sometimes iTunes starts automatically and my device can't enter pdfu or some other problems) After installing those dependencies first, the device enters DFU mode manually when connecting to the computer, and then the computer logs off once. Before logging off, do not turn on iTunes, and then turn on the computer to directly perform degradation operation, and iTunes will not automatically start (my Mac OS is 10.14.3, so I can downgrade my device with Vieux, which has never been done again. When the machine is turned on, it will fail to report an error once in a while.)

You can download an IPSW to use with PyBoot if you don't want to redownload the files everytime. Just use -q instead of -i.
