Yes you need to relock before you can run the RUU.
Don't forget that when you load one of Scott's ROMS after you flash the ROM it automatically reboots into HBOOT and will attempt(after you press power) to load the matching kernel. Amon-Ra 3.10 does not support this action and will ignore it. So if you're on Amon-Ra 3.12 or better it will work. If you get stuck on your first boot...wait. If you get impatient after 5 minutes reboot and it should boot up this time.
Ok cool I might have to try that, I prob shouldn't burn my work day tweaking this thing lol!
I have 3.14 installed (blue text I think is .14) for Amonra so I should be good.... assuming that it will install the rom. Otherwise I have till 10pm tonight till my Sim card expires according to VZW since I swapped to a 3g phone for the time being. Oh the woes haha.
