As always, great tutorial. I've used it to make a backup, but thankfully never had to use it to restore. This does lead me to 2 follow up questions/scenarios:
1. The backup is provided you can get into CWM. What if the phone can't get into CWM and is "hard bricked"? Then I assume in this case you can't do anything, correct? What if you have the backup file on your PC as you suggested. Could you somehow through ODIN restore the backup file without access to CWM (provided the phone is recognized in ODIN)? Or would you have to use ODIN to restore, get it up an running, then install CWM, then use your backup to revert back? I guess it all comes down to if it's recognized or not in ODIN, if it is, then you're not really hard bricked; but if it isn't, your SOL?
2. If the phone can boot up, and let's say is stuck in a boot loop where it doesn't get into the rom, but can get into CWM, but the backup is corrupted. How would you transfer from your PC the backup without being able to "mount" the SD card to transfer it. Obviously with an external SD it's no problem, but what if you only use the internal?
Thankfully, I've never experienced any of the issues above, I'm just curious on the answers. Thanks guys.
