I'm away from home at the moment and using a family member's computer. I have no easy way to check the rgn or remake it, but If you'd like a bit more practice you can make the kit yourself. Here's a walk thru:

Download both the 2x5W v7.60 and the 465 V4.20 firmware:

Open the 465 fw with [Only registered and activated users can see links. ] and save the fw_all.bin somewhere convenient. Then open the 265W fw and load the 465 fw_all.bin in place of the existing. Check the HWID override panel and set it to 0827 then save the combined firmware as 082701000420.rgn. If it still wont boot after flashing the re-made fw, open the hybrid rgn again with RGN_Tool and add the 465 logo into the third field. Save again as 082701000420.rgn and try again.

Don't forget to do the hard reset before and after each flashing.
