Well, dang... I've tried everything I can think of and am stuck. If any of you have suggestions, I'll be forever in your debt.

So I was trying out a few ROMS on my I747. The last working one I had was LiquidSmooth Android (v2.1 I believe) but it was rebooting on me more often than I'd like, so I tried booting into TWRP to restore my last Nandroid of the rooted stock ROM I had been running fine. I know that Nandroid backup was a good one because I have restored it before. So anyway, I boot into TWRP and suddenly TWRP asks me for a password, which it has never done before. It almost looked like TWRP thought my device was encrypted, which it wasn't. But then when I hit "cancel" and tried to use the TWRP Factory Reset wipe, all of the attempts to mount the partitions failed! So I decided to let TWRP reboot the device, thinking something weird was going on with TWRP that would be fixed the next time I loaded it (DOH!) and I've been hosed ever since.

I am in a stange position with my I747 now. The OS won't boot at all. It forces the phone to try to boot into recovery, which is the latest TWRP. Unfortunately that just hangs at the "teamwin" screen and never goes on. First thing I decided to try was to flash a fresh TWRP thinking my TWRP had gotten mucked up. When got the latest TWRP tar from your Toolkit "recovery" folder (I am a donator from a day or two ago) it looked like it successfully flashed the TWRP to the phone, although I'm a bit worried maybe I don't understand Odin's output. Here is what it shows when I flash the TWRP:

<ID:0/007> Remain Port .... 0
<OSM> All threads completed. (succeed 1 / failed 0)

The phone reboots like the re-write of TWRP was successful, but then it just hangs at the "teamwin" screen again. So then I thought I'd try flashing CWM instead.. The output from ODIN looks basically the same, but when I reboot into recovery I again am stuck at the "teamwin" screen from TWRP! WTH?

Why am I still seeing the "teamwin" screen if I just flashed CWM and Odin says it succeeded? I'm guessing it has something to do with the "RQT CLOSE !!" line in the log above. Is that actually a failure message that I thought was a success message? It isn't real clear..

So then my last fall back was just to flash the whole stock ROM again. Sadly, that didn't seem to work either. It actually gives me a WRITE (Fail!) message. Here is the output of Odin when trying to write the stock ROM to the phone in Download mode. I'm trying to flash the files called "I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.tar.md5".

As you can see, the MD5 checks passed with no problems, but the actual writing of the code to the NAND fails immediately. At this point I have no idea what to try next.

And for the record, I also tried flashing back the original boot image from your Toolkit called "boot-stock-dlk3-SGHI747.tar". Here is what I get when I try to flash that with Odin.

Any suggestions anyone might have for what to do next would be most appreciated. Sadly, this is my only phone, and my employer pays for it. I need to get it up and running as soon as I can, if it is possible. Probably shouldn't have been messing with it in the first place, but I'm a tinkerer at heart.. What can I say?

Thanks for taking the time to read this and thanks for any tips any of you can share!!
