I have the verizon Galaxy s3. I first rooted and created a nandroid backup last week. Then proceeded to install CM10 unnofficial with kexec. created a backup of cm10 unnofficial then went back to stock without any issues. Today I ran a nandroid backup (still stock) then performed the EZ bootloader unlock, and installed the official CM10 nightly. Got JB setup to my liking then ran a nandroid backup of the official CM10 8-21 build. When i try to restore the stock backups it gets an error when trying to load the sytem. Any thoughts or ideas on this? I can restore the CM10 backup from today without an issue and it runs fine. I'm thinking I might have to flash the stock image and then advance restore all parts except the system from CWM. I have tried relocking the bootloader and trying again, no luck. I'm coming from Moto so familiar with SBF. But whats the process like on sammy devices?? I've gathered that I need Odin, but where do I get the full file for the verizon galaxy s3? Also does anyone have a full system dump from the s3 (mainly looking to pull a few apps from it)?
