Really, just flash the TSOP. It's the easiest solder job *ever* (will take less than 5 min) and you never have to worry about the thing getting corrupted. Since you're already soft modded it's painless. 1) Solder two points. 2) Flash BIOS via EvoX UI. 3) Profit! -hl718
Xbox-Scene has images of all the solder points. No need to look elsewhere. Once you've connected the two solder points, the TSOP flash is writeable. From there you just boot EvoX (with an exploit if you are running the retail flash, or directly if you're already soft modded) and use the built-in flash utility to flash the BIOS of choice to the TSOP. After that shutdown and reboot. Done. -hl718
Solder points varies with the version of the board so if you post pictures I can point you where you put the jumpers. :thumbsup:
Joining the two points purely with solder can be a bit of a pain. I prefer to strip off about 1 inch of wire, tinning it and then laying it across both points heating the wire and cutting off the excess. Leaves only what you need and nothing more. Also lowers the risk of lifting a trace through accidents and/or alcohol quite a bit.
Whatever you do just back up the eeprom first, Have you found out if it's a unit that has the TSOP chip or not? If it's not TSOP then just replace the dash directory contents with the dash of your choice, But indeeded if it's got a TSOP chip then go on and flash the sucker! PROS = It lets you use any hard-drive with the Xbox & Doesn't have to be "locked" or Married to the unit. ( which is why I said get the eeprom before you decide to hose that setup with slayer's auto installer ) If that happens then it's no biggie you can rebuild the harddrive as long as you've got the eeprom to use with XboxHDM ;-) CONS = NONE AT ALL!
