I am having the same issue - I have the HTC__044 and need new firmware to get the newest ROM.
I am S-On and CANT get S-off (s-off needed to flash firmware)...firewater does not work with my phone after multiple tries.
I tried getting Sunshine to work for s-off, but I need to be on a stock Sense ROM (I am on Viper 1.8) and don't have a stock backup. I can't find ANY stock ROM's online! Once I have supercid i was going to flash firmware, but without S off...I'm going nowhere (it seems)
anyone have an idea where I should start?
