Problem Flashing Sigma X2 on SB5100

[sixteen]

Hi guys,

I obtained a virgin bin and flashed it to my SB5100. It worked fine. I next flashed Sigma X2 142 by fersca but I lost the lights on my modem. I couldn't get to the sigma page either. I flashed Sigma stealth version on top of it (Without flashing to virgin again) and it worked. I don't want the stealth version but 142 by Fersca. Does anyone know why that happened?

you brick the modem and it need debricking, i find sb5100mod work better for me tho, if you want help to debrick i can help.
