Just finished my editor for Borderlands The Pre-Sequel Profile! X360 & PC
You need to open the profile.bin file (Profile data) and then open your xbox profile.
If you don't open your profile the editor will not compute the hash correctly.
1. Extract the Profile Data save (profile.bin). Make a backup.
2. Extract your xbox live profile (EXXXXXXXXXXXXXXX). Make a backup.
3. Open the Profile Data save (profile.bin) by pressing File/Open.
4. Open your xbox live profile that is associated with the save.
5. Edit the values and press File/Save.
6. Replace the original Profile Data (profile.bin) with the modded one.
