You can save your FSC's, search for how to delete, and you will find out what to save, I don't remember exactly right now, but there are 4 files they needs to be saved. /mnt/hbuser - data 0-3 and /mnt/Hbpersistence/normal - swt controler ...
For VIN, you will have to code CIC with your VIN, or flash it with your vin, or try Esys/Fsc extended/ write identifier VIN, if your car is F series.
