Firt of All, i like to thank all you guys for spend some time reading my problem, so let me try explain what happened with my Xbox 360.
I got a benq, so i got a Iprep to flash my xbox to 1.61, no problem until now, i got via sata card, iprep found my xbox, read the banks, so when this ereasing the bank 3, my home run out of eletricity for a seconds, and them of couse my xbox turn off in the middle of process of ereasing!!! I was tryied to reflesh using the same way, booting by USB like normal, and then when i ask to read, the process begun, but when the Iprep try to erease, it got some error of check sun ffffffffffffoooooooooo and abort operation, i was tryed just write without read anything, but got the same error. Looking for some other way, i try use Jungle Flash (i´m a noob in flashing) so, when i use JF, my PC frozen.
My xbox still bliking a red light in the right corner...

Forget to say, i was tryied update to Benq LT
