I was prepearing a video about how to jailbreak iOS 7.1.2 on iPhone 4 (N90AP) using Pangu 7, but it seems that Cydia had some problems during the application stashing process. This step is also known as "Prepearing the FileSystem", after opening Cydia for the first time. When jailbreaking your iOS device, the most important thing to do before is to backup important data before doing the process. Using iTunes for backup usually do a good work.
In technical details, Application Stashing is the process where Cydia moves "/Applications" folder from the first partition (/dev/disk0s1s1) to "/var/stash/[random string]/Applications", which is on the second partition (/dev/disk0s1s2). After moving applications, a Unix symlink refeering "/Applications" folder to "/var/stash/[random string]/Applications" is made to trick the iOS system. The goal of Application Stashing is to free up disk space on the system partition (/dev/disk0s1s1) for Cydia packages, some iOS system tweaking and so.
I now have to restore (again) that N90AP.

![Futurama - Holophonor Sonnet for Leela [Piano]](https://i.ytimg.com/vi/nnynLpZVWno/mqdefault.jpg "Futurama - Holophonor Sonnet for Leela [Piano]
Here is a piano arrangment of the holophonor song played by Fry for Leela in the Parasite Lost (S03E04) episode of Futurama.
There are five softwares used in the making of this arrangement.
1 - Nero Recode (probably, I dont remember exactly): To extract the audio from the original video. Then, I cut all the audio except the holophonor part and exported to WAV format using audacity.
2 - AnthemScore: To reverse the song. This software allows me to see a visual representation of the actual song and guess notes, plus it uses an IA to automatically do a part of this work. The final product is a sheet music in MusicXML file format.
3 - MuseScore: To re-encode the MusicXML output of AnthemScore to a more versatile MusicXML format. I dont know why, but using AnthemScores MusicXML output in Synthesia doesnt work well, the BPM isnt the right one. Converting the file with Musescore will produce a MusicXML file that will be better with Synthesia.
4 - Synthesia: To get this nice piano roll and also to practice the song on a real piano.
Album : N/A
