I noticed a lot of questions on how to use the .NBH file and where to get the RomUpdateUtility(herein, RUU) is useless.
The NBH is the rom image file and without an unlocked SPL and the RUU is more or less useless for the average user.
You can use old RUUs from other/previous ROMs, but if you're like me you dont enjoy downloading 110mb for a 500kb file.
If you check the
tutorial page (who knew, right?) you'll find both the Diamond Unlocker and RUU utility.
For those of you who are lazy, here are direct links.
RomUpgradeUtility (RUU)
Diamond Unlocker
Thanks to TobeyChris for the original links... and NRGZ28 for a great rom.
Perhaps this deserves a mention in the Q&A? a lot of posts are looking for the RUU.
