He will learn eventually.

One time, I was experimenting with TimeMachine when it was first out, and I was trying to get Devhook to run. When I started the emulation, the ids that got written corrupted my ids and I could only fixed it with Pandora. :( So I went through Mediafire and found my 3.71 M33-4 nand backup. Flashed, and was safe. Nand dumps are serious things. Another friend whose PSP I hacked got his Wifi all messed up, and I couldn't find a nand/ids key backup to fix it all up.
