Hello! I believe They ask to flash because issue's do happen in most 6.5 ROM's if you just flash from ROM to ROM, I don't believe you must undo the hard spl... so no to that, and also deleting the youtube folder is really good thing to do. I can't really explain why but.... trust me if you don't your bound to run into issues mate =] hit thanks if this helped. oh yeah btw I usually just flash to sprint shipped and Don't let the cus run but that's only hen I'm in a hurry and never run into issues =] but if you have time on your hand take the time to let cus run and then go to start -> settings -> system and clear storage. or you can flash from ROM to ROM but you would have to do a hard reset after doing so and after hard reset do a clear storage as well so yeah more time wasted ;P
