SSPL (or flashing any ROM 4 free)
This tool allow to flash your Trinity ROM bypassing CID and signature(*) check.
For flashing ROM copy SSPL-TRIN.exe to your device and run it. Standart bootloader prompt should appear on screen, check SPL version number: if it ends with ".ds" then everything is fine. (Re)attach usb cable and run firmware update utility.
In case if something goes wrong during flashing you should flash your device with ROM accepted by standard bootloader (and have another try if you wish).
(*) code must be formally signed i.e. contain properly-formated signatures on their places, however no checking are performed against them. Actualy unsigned code flashing was tested by flashing original signed nbh image with few bytes in header and extrom section modified, but patches were designed to accept any properly formatted crap as a valid signature.
