Question AT&T S III won't go past the SAMSUNG logo

I have successfully flashed via ODIN 3.07 the following:
* stock bootloader that downloads with the SAMSUNG Galaxy S3 Toolkit (C:\Program Files (x86)\Samsung\Samsung Galaxy S3 ToolKit\root\SGH-I747\boot-stock-dlk3-SGHI747.tar; 5,620 KB)
* stock recovery that downloads with the SAMSUNG Galaxyy S3 Toolkit (C:\Program Files (x86)\Samsung\Samsung Galaxy S3 ToolKit\recovery\recovery-stock-dlk3-SGHI747.tar; 6,310 KB)
* stock UCDLK3 ROM from this thread (I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.tar.md5; 1,166,061 KB), which I believe also includes modem, maybe even bootloader and recovery too.

Still, my AT&T S III will not go past the glowing SAMSUNG logo.

Any ideas?

UPDATE: Factory restore in stock recovery worked.
