I understand that you have to flash back to OFW, then update and finally flash to Lt 1.9, my questions are: 1. What if you have a stock system that has the update, can you just go straight to Lt 1.9 or is it risky? 2.If you have an xbox with lt 1.1 but dont have the drive key, is updating then flashing a bad idea? 3. After flashing to 1.9 do past backups become non-playable? Thanks for the help.
