Ok so it looks like SPL-On/Off is tied to the board not the nbh. we obtained a vodaphone nbh that was newer then the mytouch nbh, with the spl .007. It flashed fine with a gold card, however i still have spl on, and i cannot downgrade to the mytouch because the version is older.
Damn so you got it flash????
I knew it!!! Can you post some more details and link to the file please.
Can you post your current SPL..
Try using the haykuro's SPL and Root procedure now...
