I have strange problems trying to update to 14699 and i'm getting real desperate here...
basics: jtag jasper16 with currently 13599 kernel and dashlaunch 2.27 installed, all running fine.
so i wanted to ugrade to metro dash (14699) and built an image using xeBuild GUI v1.1
when i flashed the image by xell, the console always freezes at the xbox logo. still i was able to fire up xell(ous). so i rebuild the image again (excluding DL2.27) and flashed it again. no change.
I have also built an image using freeBOOT ToolBox Maker v2.9.1 with the same result.
Reverting back to 13599 via xell works fine.
