This is my first attempt at a post, so please go easy on me if I don't get it done quite right.
I post this as a warning to anyone who might attempt to use Kies 3 to revert to factory firmware.
I recently started noodling with flashing ROMs, etc. Prior to that my device had received the AT&T OTA Kitkat. During my experimentation, I ended up with my I747 in a soft brick - VERY scary to a person new to this type of thing. Of the many things I tried in an attempt to regain functionality, one was to connect to Kies 3 and let it try to revert my device to stock ROM. I downloaded and installed the latest version of Kies 3 on my PC. When I started it and connected the device, in download mode, it recognized that my device was connected to my PC, recognized my model number and serial number, and said it could do a recovery. All seemed well, so I agreed to all the dire warnings and told Kies to proceed. After it finished, I discovered that Kies was flashing an older version of firmware (I don't recall which one, but older than KitKat). I should have paid more attention to the firmware version Kies said it was going to install, but I assumed (I know, I know) Samsung's own software would be smart enough to not push old software that would brick at device that AT&T already had updated to Kitkat (or does Samsung do the updates on behalf of AT&T?).
Fortunately the soft brick after Kies was no worse than the soft brick before Kies, but I still find it had to believe that Samsung's own Kies (version 3) program pushed an older version that could not work with the current, up-to-date OTA on my phone. I had just downloaded and installed Kies, for the purpose of this recovery, so Kies was up to date.
Again I post this as a warning to other noobies who might try to use Kies 3 to return to factory software.
