AT&T Production Stock Firmware (I987UCJK1)
Here is an ODIN package for the stock firmware from the AT&T Galaxy Tab at release time. (I987UCJK1, not an engineering or preproduction ROM) It was tested by rotohammer on a T-Mobile Galaxy Tab. (Thanks for testing it for me)
It was created using the same method that the stock T-Mobile flash was created, so there is not a bootloader in this package.
Flash using ODIN by putting it into the PDA field, no pit or other packages required.
Thanks to rotohammer and all of the others participating in thread about creating a usable dump.
