Hi.
I had same problem with dead i9100G,after resurection with Omapflash Tool no Download Mode,only Samsung Logo,after reset Device again dead.
I have successfull repair with this Guide:
Start Omap Tool and connect the i9100G without Battery,after successfull write SBL.bin
Code:
» Downloading 'Targets\Projects\espresso\Sbl.bin'
» Sending data (1310720 bytes) :::::::::::::::::::: [1310720]
» Downloading complete
» Elapsed time: 0:00.906 (1446710 bytes/s)
» cold_sw_reset
» Elapsed time: 0:11.500
Premere un tasto per continuare . . .
quickly disconnect USB Cable and put Battery in to i9100G and use USB JIG,you have now Download Mode and can flash with ODIN 3-Parts Firmware(Boot,PDA,Phone,CSC),only this Methode work by me on i9100G after flash wrong Firmware from i9100.
