Don't waste your time!
If any of you see all these posts out on the net about unlocking the boot-loader of the Samsung Galaxy S3 mini SM-G730A do yourself a favor keep going on to the next article, you'll saving yourself allot of grief! All of them are full or bologna to put it frank! I have broke it twice now and am convinced it isn't worth the trouble. I have found that odin and the original image can be restored and put the phone back in working order. I have also been able to root the device with little trouble but that is it. Anything else and the unit just keeps rebooting in recovery mode and then you have to wipe it out again and start over. I, on the other hand, have been successful at rooting and unlocking my Motorola Atrix HD MB886 and it is working great. But the Samsung is a for sale or a drawer phone because it is not going to be unlocked anytime soon I fear.
