I second the motion for more input from the people who have successfully flashed the SHARP LH28F008SCT TSOP.
I have read, like many others, all i can find about flashing the sharp tsop. I have also tried to adapt methods that were for other brand tsops. My setup is a V1.2 NTSC Xbox with a 1MB Sharp LH28F008SCT Tsop. I have solder joined the two WE point at the bottom and connected the two that are far from each other (LPC and P11 i believe). I have soldered two seperate wires from the top two points so i can "twist" them together shortly after i boot the xbox.
So far i have tried to :
1) flash using the Evox_Matrix bios in conjuction with Xecuter 2.1 Lite. By the way works with any of the other brand 1MB bios's. Problems i ran into was i was getting black screen. For some reason it didn't want to boot with the Evox_Matrix bios. Remember i have done this before on other brand TSOP's.
2) flash using Mech Assault Exploit. I first ran into problems with unsigend "default.xbe", fixed this problem and Evox would boot when loading the MechAssault saved game file from HDD. Problem i'm having with this is that the Sharp TSOP won't erase. It just sits there and the indicator bar doesn't move at all. As for the top bios enable points, i would have them touch and remain touching soon after i boot the xbox, load game save -> Evox loads -> continue onto flashing bios -> Evox detects bios (the TSOP definition in the evox.ini file had i "#" infront so i deleted the "#" to enable Evox to recongnize the TSOP) -> press "Y" to start the erasure process -> just hangs and sits there doing nothing.
Boy am i loosing alot of sleep and hair from this SHARP TSOP. Hope someone can save me!, and all the others who have or soon will come across these SHARPS.
BTW here is the evox.ini line that i use for the SHARP:
Flash = 0x89a6,"SHARP - LH28F008SCT",0x100000,0x20,0xd0,0x10
