Backup Verizon Stock ROM & EPST

[mvincent]

Can someone point me to the correct instructions to backing up your own Verizon rom before making changes/upgrades on my xv6800?.

I assume for the ROM I need to unlock with Coke unlocker or something first ???? and then what do I use to actually dump the rom?

As for the EPST information, where is this stored as I want to copy this over in the event of loss.

Any assistance would be greatly appreciated. Thanks
