I followed the following instructions and created a backup.
Create BackupI always create backup just to be safe)
Turn off phone and turn on while holding x.(hold x before and after turning on the phone)
You should see Welcome to SPRecovery in the middle of the screen.
Using the D-pad select backup/restore(left is up and right is down to select use center button)
Select Advanced Nandroid backup
Select Set backup name and type a name pressing enter when done.(example: stockfullbackup)
Now select backup CACHE, MISC and RECOVERY.(this should make every option have an * next to it)
Select Perform backup
Once complete Reboot and backup your SD card to your PC.
The backup file folder was saved in nandroid folder, I took it out and put it in clockwork/backup, when i press x and power and restore, it says error while restoring /system/. I installed the BB .4 rom, but realized I had forgotten to make a copy of my apps, I wanted to load by previous nandroid restore, but I get the error message.
Did I royally screw something up? Is all my data lost?
