Hello, I'm searching for 9070 service firmware. Works only download mode, flashing original FW didn't help, can't do wipes, recovery mode don't works.
If the download mode works then you are good. Just flash the JB firmware (single file) using odin.
Then if you want to go for GB then read the following guide: http://forum.xda-developers.com/show...php?p=36744120
The GB has 3 files to flash - you will find them here - keep searching.
